• High-efficiency, variable-speed condenser fans (30RB080-390 with Greenspeed technology)
Features/BenefitsCarrier’s superior chiller design provides savings at initial purchase, at installa-tion, and for years afterward.Costs less right from the startCarrier’s AquaSnap chillers feature a compact, all-in-one package design that installs quickly and easily on the ground or the rooftop. The optional pump and hydronic components are already built in; this costs less than buying and install-ing the components individually. The chiller’s fully integrated and pre-assem-bled hydronic system installs in minutes. No other chiller in this class installs so easily and inexpensively. The preassem-bled and integrated hydronic module (available with VFD) utilizes top-quality components and pumps to ensure years of reliable operation. The AquaSnap unit’s high efficiency keeps operating costs down.
AquaSnap®
30RB060-390 Air-Cooled Chillers and30RB080-390 Air-Cooled Chillers with
AquaSnap® chillers make noise in the marketplace, not the workplaceThe AquaSnap chiller’s AeroAcous-tic™ fan is almost twice as quiet as the competition’s per cfm. Much of the noise reduction is in frequencies where noise is most annoying, which makes AquaSnap chillers ideal for sound-sensitive environments. When lower ambient temperatures allow part load operation or during scheduled night-time operation, the units operate with fewer fans and become even quieter. AquaSnap chillers are quiet during the day and even quieter at night.
The savings will continue to mountBesides costing less to buy and install, AquaSnap chillers are also more af-fordable to operate. Carrier’s AquaSeries chillers are our most efficient air-cooled models. The 30RB chillers provide full-load EER (Energy Efficien-cy Ratio) up to 10.3. The 30RB chiller provides an IPLV (integrated part load value) up to 14.3, while the 30RB chiller with Greenspeed® technology provides an IPLV up to 17.1. AquaS-nap chillers use ultra-quiet, high-effi-ciency rotary scroll compressors, oper-ated in tandem, trios or quads per in-dependent circuit for greater efficiency at partial loads.30RB chillers with Greenspeed technology feature a high-efficiency, variable-speed condenser fan option along with fine-tuned ComfortLink controls, which together provide pre-mium part load efficiency to facilitate reduced utility costs over the lifespan of the chiller. Additionally, the lower sound levels achieved at part load con-ditions can be very beneficial for sensi-tive acoustic applications.Electronic expansion valve (EXV) allows for precise control through all operating ranges, resulting in higher efficiencies.
Proven reliability that is built inThousands of AquaSnap chillers arealready in service around the world. This field-proven design is backed by a12-month warranty that includes the optional hydronic system (U.S. and Canada only). The compressors are maintenance-free and protected by an auto-adaptive control that minimizes compressor wear. Year-round opera-tion is standard, from –20 F (–29 C)
(with optional cooler heater and low ambient control) to 125 F (52 C).Rotary scroll compressors provide smooth, quiet and reliable operation.Multiple independent circuits are standard on all AquaSnap chillers for redundancy and greater reliability.
All-in-one packageAquaSnap chillers provide the most comprehensive chilled water circuit available for any air-cooled chiller.Included is a shell-in-tubedirect expansion cooler that may be remote-mounted. The cooler is also completely drainable with factory-installed vents and drains.Electronic thermal-dispersion flow switch is included with the cool-er. The switch is factory installed and tested and contains no moving parts for high reliability.Optional integrated hydronics package is more than just a pump, it is an entire chilled water system,including:• Single/dual pumps up to 15 hp
and 140 ft (42.7 m) head• Availability at constant speed or
VFD configuration• Regular strainer• Cleanout strainer• Flow regulator• Freeze protection to –20 F (–29 C)
dronics package provides faster, sim-pler and less expensive installation.
Environmentally balancedCarrier’s Puron® refrigerant (R-410A) enables you to make a responsible de-cision in the protection of the earth’s ozone layer. Puron refrigerant is an HFC refrigerant that does not contain chlorine that is damaging to the ozone layer. Puron refrigerant is unaffected by the Montreal Protocol. Puron refrig-erant is a safe, non-toxic, efficient and environmentally balanced refrigerant for the future.
Structurally soundThe base rail is industrial-quality 7 ga for maximum structural integrity. The zinc-dipped galvanized frame (with Ser-maGuard� coated screws) provides
the best protection on the market for corrosion resistance. With such a struc-turally sound base, no perimeter base rail is needed.
ComfortLink controls speak your languageThe ComfortLink controls communi-cate in plain English, making it as easy as possible to monitor and control each AquaSnap chiller while accurately maintaining fluid temperatures. The large scrolling marquee display acts as a window into the unit’s operation, providing easy-to-read information about chiller performance and over15 diagnostic functions. Carrier’s 30 Series chillers’ ComfortLink controls provide features such as chilled water temperature reset, demand limiting, compressor wear minimization and protection, temperature and pressure displays and diagnostic functions. These controls result in higher chiller reliability, simplified training and more productive service calls with corre-spondingly lower operational and maintenance costs.
Carrier’s exclusive handheldNavigator™ display provides conve-nience and powerful information in the palm of your hand. The Navigator display helps technicians to quickly diagnose problems and even prevent them from occurring.
All AquaSnap units are ready to be used with the Carrier Comfort Network® (CCN) system.
A BACnet* communication option is also available for the i-Vu® Open con-trol system or a BACnet building auto-mation system.
Novation® heat exchanger technologyThe Novation heat exchanger design with microchannel (MCHX) condenser coil is a robust, cost effective alterna-tive to traditional coil design. These coils are offered coated or uncoated to match coil protection to site condi-tions. The Carrier Electronic Catalog (E-Cat) can be used to determine whether or not corrosion protection is recommended for particular applica-tions in coastal/marine environments. Following the input of the requested data, the E-Cat program output will ad-vise the appropriate coil to be used.

Other factors described in "Selection Guide: Environmental Corrosion Protection" catalog number 04-581061-01 must also be consid-ered to determine if corrosion protec-tion is required. Microchannel coils are sturdier than other coil types, making them easier to clean without causing damage to the coil.
Due to the compact all-aluminumdesign, microchannel coils will reduce overall unit operating weight by 6 to 7%. The streamlined MCHX coil de-sign reduces refrigerant charge by up to 30%. The coil is designed with rubber iso-lation around the powder painted coil frame to eliminate galvanic couples, which can cause corrosion due to dis-similar metals.
Optional integrated heat reclaim packageFor applications with a simultaneousrequirement for chilled water and tem-pered heat water, the heat reclaimoption is an ideal solution. The produc-tion of useful hot water in conjunctionwith useful chilled water can lead tototal COP (coefficient of performance)values greater than 6.0.

Carrier’s NACO (North American Commericial Opera-tions) Packaged Chiller Builder Program provides quick,easy selection of Carrier’s air-cooled liquid chillers. Theprogram considers specific temperature, fluid and flowrequirements among other factors such as fouling andaltitude corrections.
Before selecting a chiller, consider the following points:Leaving water (fluid) temperature (LWT)• If the LWT is less than 40 F (4.4 C), loop freeze protec-
tion to a minimum of 30° F (16.6° C) below the LWTset point is required.
• If the LWT is to be between 15 F and 30 F (–9.4 C and–1.1 C) and the unit size is 30RB060-100, then bothsuction line insulation and low ambient head pressurecontrol (or 30RB chiller with Greenspeed® technology)must be included. For unit sizes 30RB110-390, opera-tion below 30 F (–1.1 C) is not available.
• If the LWT requirement is greater than 60 F (16 C), amixing loop is required.
Entering water temperature (EWT)• If the EWT requirement is greater than 70 F (21.1 C), a
mixing loop is required. The EWT cannot exceed 70 F(21.1 C) for extended operation. Pulldown can beaccomplished from 95 F (35 C).
Cooler flow rate or cooler delta-T• The cooler delta-T must fall between 5 and 20° F (3 and
11° C).• For larger or smaller delta-T applications, a mixing loop
is required.• If the cooler flow is variable, then the rate of change of
flow should not exceed 10% per minute. A loop volumeof greater than 3 gallons per ton (3.25 L per kW) isrecommended.
Cooler pressure drop• A high cooler pressure drop can be expected when the
cooler delta-T is low. A mixing loop can help to alleviatethis situation.
Water quality, fouling factor• Poor water quality can increase the cooler fouling.• Higher than standard fouling factors lead to lower
capacity and higher input kW from a given chiller sizecompared to running the same application with betterquality water (and lower fouling factors).
Operation below 32 F (0° C)• Low ambient head pressure control (or 30RB chiller
with Greenspeed technology) is required.• Consider wind baffles if average wind speed is greater
than 5 mph (8 kph).• Consider higher loop volumes, 6 to 10 gallons per
nominal ton (6.5 to 10.75 L per kW).• Loop freeze protection with glycol is strongly recom-
mended to a minimum of 15° F (8° C) below lowestanticipated ambient temperature.
• Cooler heater option is required if no glycol is used.• Chilled water pump control is strongly recommended;
otherwise override capability is required.• Consider the remote cooler option. Do not bury refrig-
erant piping.
Chiller idle below 32 F (0° C)• Loop freeze protection with glycol is strongly recom-
mended to a minimum of 15° F (8° C) below lowestanticipated ambient temperature.
• Cooler heater option is required if no glycol is used.• Chilled water pump control is strongly recommended;
otherwise override capability is required.• Drain the cooler — This will require a small amount of
glycol for residual water. Cooler heaters (if provided) willneed to be disconnected.
• Consider the remote cooler option. Never bury refriger-ant lines.
Highest allowable ambient air temperature is 125 F (52 C).Cooling capacity requirements• Do not oversize the chillers by more than 15% at design
conditions.• If close capacity control is required below the standard
minimum step of unloading, the minimum load controloption should be employed.

To select a chiller, use the Packaged Chiller BuilderProgram or follow one of the procedures starting onpage 41.
Optional heat reclaim checklist (projectsuitability for heat reclaim)• There must be a simultaneous requirement for chilled
water and hot water.• Hot water temperatures from the heating system must
be in the range of 68 to 120 F (20 to 49 C), with hotwater flow in the range of 2 to 4 gpm (0.13 to0.25 L per minute) per heating ton.
• The chilled water load must be in the range of 60 to190 tons (211.2 to 668.8 kW).
• The hot water load must fall in the range of 770 to2,650 MBH (1000 Btu per hour) (812 to 2795 nM/hr)per chiller.
Selection procedure
47
NOTE: There is minimal impact on chiller cooling perfor-mance and efficiency when the heat reclaim option isselected. As in all cases, performance data associated withthe 30RB heat reclaim chiller is to be determined from thecurrent version of the chiller selection program.
English ExampleI Determine 30RB unit size and operating
conditions required to meet given capacity atgiven conditions.Given:Capacity. . . . . . . . . . . . . . . . . . . . . . . . 126 TonsLeaving Chilled Water Temp (LCWT) . . . . . . .44 FCooler Water Temp Rise . . . . . . . . . . . . . . . 10° FCondenser Entering Air Temp . . . . . . . . . . . .95 FFouling Factor (Cooler) . . . . . . . . . . . . . .0.00010NOTE: For other than 10° F (5.6° C) temperaturerise, unit selection must be made using the chillerprogram in the electronic catalog.
AquaSnap® pump selectionSeveral pump sizes are available for each AquaSnap chillersize to provide flexibility in matching water system require-ments. A dual pump option is also available for primary/standby operation. The Carrier Packaged Chiller BuilderProgram must be used for pump selection. Pump packagesare available in both constant speed and VFD configura-tions.NOTE: The pump option is not available with units withoptional heat reclaim.
Proper water system design is critical; cooling loads,water pressure drops and proper water line sizing must beaccounted for in order to ensure proper system operation.Incorrect or incomplete analysis/design of the water loopcould lead to low water flow, loss of water temperaturecontrol, and excessive cycling of chiller compressors.
PUMP IMPELLER SIZES
*Option Code refers to the Hydronics Option (position 11) in themodel number. See the 30RB nomenclature on page 4 for optionidentification.
NOTE: Pump Selections are chiller size dependent. For example,dual pump “C” on a 30RB170 chiller is not the same as dual pump“C” on a 30RB130 chiller. The pump option is not available withoptional heat reclaim. 30RB chillers with Greenspeed® technologyare not available for size 060 and 070.

MicroprocessorThe ComfortLink microprocessor controls overall unit oper-ation. Its central executive routine controls a number of pro-cesses simultaneously. These include internal timers, readinginputs, analog to digital conversions, fan control, displaycontrol, diagnostic control, output relay control, demandlimit, capacity control, head pressure control, and tempera-ture reset. Some processes are updated almost continuously,others every 2 to 3 seconds, and some every 30 seconds.The microprocessor routine is started by switching theEmergency ON-OFF switch to ON position. Pump controlof external pumps (where so configured) or optional internalpump, will energize the cooler pump to the internal (orCCN) time schedule (or input occupied signal from externalsystem).
Where dual pumps are utilized only one pump will beoperated at a time. The control will start the pump with theleast hours. When the unit receives a call for cooling (basedon a deviation from chilled water set point), the unit stagesup in capacity to maintain the cooler fluid set point. Thefirst compressor starts 1 to 3 minutes after the call for cool-ing. The ComfortLink microprocessor controls the capac-ity of the chiller by cycling compressors at a rate to satisfyactual dynamic load conditions. The control maintainsleaving-fluid temperature set point shown on the scrollingmarquee display board through intelligent cycling. Accu-racy depends on loop volume, loop flow rate, load,outdoor-air temperature, number of stages, and particularstage being cycled off. No adjustment for cooling range orcooler flow rate is required, because the control automati-cally compensates for cooling range by measuring bothreturn-fluid temperature and leaving-fluid temperature.This is referred to as leaving-fluid temperature control withreturn-fluid temperature compensation.
The basic logic for determining when to add or remove astage is a time band integration of deviation from set pointplus rate of change of leaving-fluid temperature. Whenleaving-fluid temperature is close to set point and slowlymoving closer, logic prevents addition of another stage.
If 1° F per minute (0.6° C per minute) pulldown control hasbeen selected (adjustable setting), no additional steps ofcapacity are added as long as the difference between leaving-fluid temperature and set point is greater than 4° F (2.2° C)and rate of change in leaving-fluid temperature is greater thanthe selected pulldown control rate. If it has been less than90 seconds since the last capacity change, compressors willcontinue to run unless a safety device trips. This preventsrapid cycling and also helps return oil during short on periods.
SensorsThermistors are used to control temperature-sensing inputs tomicroprocessor. Additional thermistor sensors may be used asremote temperature sensors for optional LCWT (leavingchilled fluid temperature) reset.• Cooler leaving chilled fluid temperature (T1)• Cooler entering fluid (return) temperature (T2)• Outside-air temperature (T9)
Two refrigerant pressure transducers are used in eachcircuit for sensing suction and discharge pressure. The
microprocessor uses these inputs to control capacity andfan cycling.• Saturated condensing temperature• Cooler saturation temperature
Control sequenceOff cycle — If ambient temperature is below 36 F (2 C),cooler heaters (if equipped) are also energized.Start-up — After the control circuit switches on, the pre-start process takes place, then microprocessor checksitself, starts pump (if configured) and waits for temperatureto stabilize. The controlled pulldown feature limits com-pressor loading on start-up to reduce demand on start-upand unnecessary compressor usage. The microprocessorlimits supply-fluid temperature decrease (start-up only) to1° F (0.6° C) per minute.Capacity control — On first call for cooling, micropro-cessor starts initial compressor and fan stage on leadcircuit.
As additional cooling is required, additional compressorsare energized.
Speed at which capacity is added or reduced is con-trolled by temperature deviation from set point and rate oftemperature change of chilled fluid.
The Main Base Board (MBB) responds to the supplychilled water temperature to cycle the compressors tomatch cooling load requirements.
Minimum load control valve is energized by the MBB.Valve allows hot gas to pass directly into the cooler circuiton the final step of unloading, permitting the unit to oper-ate at lower loads with less compressor cycling.
Additional informationDetailed information on controls and operation is availablein the Controls, Start-Up, Operation and Troubleshootingguide included with each unit. Packaged Service Trainingprograms are also available. Contact your Carrier repre-sentative for more information.High-efficiency variable condenser fans (30RBchillers with Greenspeed® technology only) — Allfans on a circuit run at the same speed and are controlledby a VFD with special CCN software to maintain SCT (sat-urated condensing temperature) set point. The set point iscalculated from operating conditions and adjusted to themost efficient operating point. The high-efficiency variablecondenser fan option uses Danfoss VLT 102 variable fre-quency drives, each with a display. Drives are connectedto the LEN communication bus. Fan speed is determinedby the chiller controller and communicated to the drive toprovide excellent part load efficiency and reduced soundlevel operation over the life of the chiller. Dual chiller control — The ComfortLink controllerallows 2 chillers (piped in parallel) to operate as a singlechilled water plant with standard control functions coordi-nated through the master chiller controller. This standardComfortLink feature requires a communication linkbetween the 2 chillers and, in the case of parallel chillers,requires an additional thermistor and well for each chiller.
Controls

Dynamic ComfortLink controls — Dynamic Com-fortLink�controls keep the chiller on line during periods ofextreme operating conditions. If the entering fluid temper-ature is 85 F (29 C) or higher and the saturated suctiontemperature is 50 F (10 C) or higher the maximumoperating pressure (MOP) feature limits the suction to keepthe chiller online. The control automatically starts thechiller in the unloaded state to eliminate the potential ofcompressor overload due to high head pressure or low suc-tion pressure. The controller will equalize run time on eachcircuit through the lead/lag feature. If a circuit becomesdisabled, the control will automatically set the active circuitto lead, keeping the chiller online at a reduced capacity.
CAPACITY CONTROL STEPS*
*Capacity control steps may vary due to compressor sequencing.
Standard ComfortLink controls with scrollingmarquee display — A four-digit alphanumeric displayshows all of the ComfortLink control codes (with 60-char-acter expandable clear language), plus set points, time ofday, temperatures, pressures, and superheat. Additionalinformation can be displayed all at once with the accessoryNavigator™ display.Navigator display — An optional 4-line, 20-characterper line display an also available as a field-installedaccessory.Low-temperature override — This feature preventsLCWT from overshooting the set point and possibly caus-ing a nuisance trip-out by the freeze protection.High-temperature override — This feature allowschiller to add capacity quickly during rapid load variations.Abnormal conditions — All control safeties in chilleroperate through compressor protection board or controlrelay and microprocessor.
Loss of feedback signal to the MBB will cause the com-pressor(s) to shut down. For other safeties, microprocessormakes appropriate decision to shut down a compressordue to a safety trip or bad sensor reading and displaysappropriate failure code on the display. Chiller remains insafety mode until reset. It then reverts to normal controlwhen unit is reset.
Low-pressure safety — Safety cuts out if system pres-sure drops below minimum.High-pressure cutout — Switch shuts down compres-sors if compressor discharge pressure increases to641 psig (4420 kPa).Compressor anti-cycling — This feature limits com-pressor cycling.Loss of flow protection — Proof of flow switches arestandard and installed on all 30RB chillers.Sensor failures — Failures are detected by themicroprocessor.
Temperature resetThe energy management module (EMM) is required for 4to 20 mA reset of LCWT in constant fluid systems. Resetby return fluid, outdoor-air temperature, or space tempera-ture does not require this option. Reset reduces compres-sor power usage at part load when design LCWT is notnecessary. Humidity control should be considered sincehigher coil temperatures resulting from reset will reducelatent heat capacity. Three reset options are offered, basedon the following:Return-fluid temperature — Increases LCWT set pointas return (or entering) fluid temperature decreases (indicat-ing load decrease). Option may be used in any applicationwhere return fluid provides accurate load indication. Limi-tation of return fluid reset is that LCWT may only be resetto value of design return fluid temperature.Outdoor-air temperature — Increases LCWT as out-door ambient temperature decreases (indicating loaddecrease). This reset should be applied only where outdoorambient temperature is an accurate indication of load. Anaccessory thermistor is required.Space temperature — Increases LCWT as space tem-perature decreases (indicating load decrease). This resetshould be applied only where space temperature is anaccurate indication of load. An accessory thermistor andthe energy management module accessory is required.
For details on applying a reset option, refer to unitControls and Troubleshooting literature. Obtain orderingpart numbers for reset option from the PackagedChiller Builder program or contact your local Carrierrepresentative.
Accessory controlsDemand can be limited by controlling the chiller capacitythrough the demand limit control (the energy managementmodule is required for this function). This factory-installedoption or accessory interfaces with microprocessor to con-trol unit so that chiller’s kW demand does not exceed itssetting. It is activated from an external switch or a 4 to20 mA signal.
The standard ComfortLink controller is programmed toaccept various accessory temperature reset options (basedon outdoor-air temperature [std], return-fluid temperature,or space temperature), that reset the LCWT. An accessorythermistor (T10) is required if outdoor-air temperature orspace temperature reset is selected. The energymanagement module (EMM) is only required for tempera-ture reset that is initiated by a 4 to 20 mA signal.
Demand limitIf applied, limits the total power draw of unit to selectedpoint by controlling number of operational compressorsduring periods of peak electrical demand.
The energy management module is required for either 2-step or 4 to 20 mA demand limit.
Electronic expansion valve (EXV)The EXV controls refrigerant flow to the cooler for differ-ent operating conditions by moving an orifice to increaseor decrease the flow area through the valve based onmicroprocessor input. The orifice is positioned by a step-per motor through approximately 3,600 discrete steps andis monitored every three seconds. The EXV maintains anapproximate 8° F (5° C) refrigerant superheat entering thecompressor.
DiagnosticsThe microprocessor may be put through a service test (seeControls, Start-Up, Operation, Service, and Troubleshoot-ing literature). Service test confirms microprocessor isfunctional, informs observer through display the conditionof each sensor and switch in chiller, and allows observer tocheck for proper operation of fans and compressors.
Default settingsTo facilitate quick start-ups, 30RB chillers withComfortLink controls are pre-configured with a defaultsetting that assumes stand-alone operation supplying 44 F(6.7 C) chilled water.
Configuration settings will be based on any optionsor accessories included with the unit at the time ofmanufacturing.
Date and time are set to U.S.A. Eastern Time zone andwill need reconfiguring based on location and local timezone. If operation based on occupancy scheduling isdesired, this will also need to be set during installation.
Ice dutyComfortLink controls have the capability of reduced leav-ing fluid temperature operation for thermal storage, or iceduty. On unit sizes 060-100 the optional energy manage-ment module includes input contacts for the “ice done” sig-nal generated by the thermal storage control system. Theice duty feature may be configured to start on an externalinput command or by the ComfortLink standard internalscheduling function. Ice duty may be used in combinationwith any other standard features offered by the energymanagement module and ComfortLink controls.
The production of ice, which is stored for peak coolingdemands, can significantly decrease energy costs. The unitproduces ice (normally at night) by supplying ice storagetanks with low temperature cooling fluid. The chiller takesadvantage of reduced ambient conditions at night for ice-making mode, so the capacity suffers a lower penalty forthe low leaving fluid temperatures.
At peak cooling demands the chiller and the stored icemay share the cooling load to reduce operating costs. Thethermal storage system may potentially reduce the size ofthe chiller plant required to meet demand loads.
Heat reclaim optionThe heat reclaim option is available for 30RB060-190chiller applications in which the customer has a simultane-ous need for chilled water and tempered hot water.Whether or not the heat reclaim mode is in operation, thechiller always controls the leaving chilled water tempera-ture set point. When in the heat reclaim mode, the tworefrigerant circuits are independently controlled, whichmeans that one circuit can be in the standard cooling modewhile the other circuit is in the heat reclaim mode. Thispermits two heat reclaim control stages (100% heatreclaim if both circuits are in heat reclaim mode andapproximately 50% heat reclaim based upon the size ofthe operating circuit). The intermediate stages are obtainedby cycling between the cooling-only mode and the heatreclaim mode. When the heat reclaim mode is enabled (local mode, cus-tomer remote contact or CCN control), and the return(entering) hot-water temperature is below the customer-adjustable set point, one circuit is switched to the heatreclaim mode. In this mode, the chiller is operating with awater-cooled condenser on one circuit and an air-cooledcondenser on the other circuit. Depending upon hot-watertemperature requirements, the second circuit may also beswitched to the heat reclaim mode (providing full heatrecovery in this mode of operation). The hot water temper-ature is controlled by the cycling of each refrigerant circuitbetween the air-cooled and heat reclaim modes. When thehot water set point is satisfied, the chiller will transitionback to the cooling-only mode and operate as a conven-tional air-cooled chiller. The heat reclaim option is provided with an additionalfactory-installed board. The functions controlled by thisboard include control of:• a customer-supplied heat reclaim condenser pump• a customer-supplied 3-way valve• a factory-supplied heat reclaim condenser heater• a series of solenoid valves. Changeover from the cooling-only mode to the heatreclaim mode involves the generation of a signal to startthe heat reclaim condenser pump and pump flow verifica-tion via the condenser water flow switch. If the condenserwater flow switch contacts remain open for more than aminute after the signal has been sent to the pumps, the cir-cuit remains in the cooling mode and an alarm isgenerated. When operating in the heat reclaim mode, proper headpressure must be maintained. In order to accomplish this, a3-way water valve must be field-installed and located within40 ft (12.2 m) of the heat reclaim condenser. This valvewill facilitate cold water start-up (water temperatures below59 F [15 C]), and it also will be able to maintain properhead pressure during heat reclaim operation. The mini-mum position of this water valve must be set at 20%, andthe maximum position of the valve must be set at 100%. A0 to 10 vdc control signal from the heat reclaim board willbe used to control the position of the valve.

Chiller location and clearancesDo not locate near sound sensitive areas without properacoustic consideration. For applications requiring mount-ing a chiller on a building rooftop, consideration should begiven to using rubber-in-shear or spring isolators to mini-mize structure-borne transmission. Unit must be level wheninstalled to ensure proper oil return to the compressors.Clearances must be provided around chillers for airflow,service and local code requirements. See dimensionaldrawings for specific unit clearance requirements. Ensureadequate clearance between adjacent chillers is main-tained. A minimum of 10 ft (3048 mm) is recommended.Chiller fan discharge must be at least as high as adjacentsolid walls. Installation in pits is not recommended.
Minimum clearancesThe recommended minimum clearance to ensure properairflow through the condenser coils and to allow fan main-tenance is as shown below.
Acceptable clearance on the cooler connection side orend opposite the control box of the unit can be reduced to3 ft (1 m) without sacrificing performance as long as theremaining three sides are unrestricted. Acceptable clear-ance on the side with a control box can be reduced to 4 ft(1.3 m) due to NEC (National Electric Code) regulations,without sacrificing performance as long as the remainingthree sides are unrestricted. Clearances between chillers indual chiller applications may be reduced to 6 ft (1.8m) with-out sacrificing performance provided the remaining sidesare unrestricted. For acceptable clearance with layoutinvolving more than 2 chillers, please contact applicationengineering.
Oversizing chillersOversizing chillers by more than 15% at design conditionsmust be avoided as the system operating efficiency isadversely affected (resulting in greater or excessive electri-cal demand). When future expansion of equipment isanticipated, install a single chiller to meet present loadrequirements and add a second chiller to meet the addi-tional load demand. It is also recommended that 2 smallerchillers be installed where operation at minimum load iscritical. The operation of a smaller chiller loaded to agreater percentage over minimum is preferred to operatinga single chiller at or near its minimum recommended value.Minimum load control should not be used as a means toallow oversizing chillers. Minimum load control should begiven consideration where substantial operating time isanticipated below the minimum unloading step.
Piping duplex units — The 30RB duplex chillers (sizes315 - 390) are shipped and rigged as 2 separate units. Theunits must be piped in parallel. If units are to be alignedend-to-end, minimum spacing of 42 to 48-in. (dependingon local codes) between chillers is recommended to provideadequate service access and piping clearance.
Multiple chillersWhere chiller capacities greater than can be supplied by asingle 30RB chiller are required, or where stand-by capa-bility is desired, chillers may be installed in parallel. Unitsmay be of the same or different sizes with this piping ar-rangement. However, cooler flow rates must be balancedto ensure proper flow to each chiller. Unit software is capable of controlling two parallel unitsas a single plant by making use of the dual chiller controlfeature. Refer to the Controls, Start-up, Operation, Serviceand Troubleshooting guide for further details. The accesso-ry Chillervisor System Manager can be used to ensureproper staging sequence of up to 8 chillers. Refer to theaccessory Chillervisor System Manager installation instruc-tions for further details. If the dual chiller algorithm is used, and the machines areinstalled in parallel, an additional chilled water sensor mustbe installed for each module. For 30RB315-390, where itis understood that these are duplex chillers comprised of 2chillers to be installed in parallel, two factory-suppliedthermistors and wells are shipped in the control box of oneof the modules (for other 30RB chiller sizes which will beinstalled in a parallel piping configuration, a dual chiller ac-cessory kit is available). Install one thermistor and well perchiller in the common leaving water header. Parallel chiller control with dedicated pumps is recom-mended. The chiller must start and stop its own waterpump located in its own piping. Check valves are requiredat the discharge of each pump (when the factory hydronicpackage option is chosen, and dual pumps are select-ed, the check valves are automatically supplied). Ifpumps are not dedicated for each chiller, then isolationvalves are required. Each chiller must open and close itsown isolation valve through the unit control (the valve mustbe connected to the pump outputs). Refer to the chillerpiping configuration shown on the next page. If a series application is required, the master/slave con-trol feature cannot be used. Hydronic pump packages maynot be applied in series applications.

Series chillers Where a large temperature drop (greater than 20 F[11.1 C]) is desired or where chiller capacities greater thancan be supplied by a single 30RB chiller are required orwhere standby capability is required, chillers may beinstalled in series. The leaving fluid temperature sensorsneed not be relocated. However, the cooler minimumentering fluid temperature limitations should be consideredfor the chillers located downstream of other chillers. Use ofreduced pass heads may be required to keep water-sidepressure drop at an acceptable level. When chillers areoperated in a series arrangement, the use of a ChillervisorSystem Manager is recommended.
Cooler water temperature1. Maximum leaving chilled water temperature (LCWT)
for the unit is 60 F (15.6 C). Unit can start and pulldown with up to 95 F (35 C) entering-water tempera-ture. It is recommended that entering-water tempera-ture not exceed 70 F (21.1 C).
2. Minimum LCWT for standard unit is 30 F (–1.1 C).For leaving-fluid temperatures between 15 and39.9 F (–9.4 C and 3.3 C) an inhibited antifreezesolution is required. Application of chiller to 15 F(–9.4 C) is standard on unit sizes 30RB060-100 pro-vided that the unit is supplied with suction line insula-tion and low ambient head pressure control oroptional 30RB chillers with Greenspeed® technology.For unit sizes 30RB110-390, applications with leav-ing fluid temperatures below 30 F (–1.1 C) are notavailable.
NOTE: Water flowing through cooler should not exceed100 F (38 C).
StrainersIt is recommended that a strainer with a minimum of 20mesh be installed in the cooler fluid inlet line, just ahead of(and as close as possible) to the cooler.
Cooler flow/rangeRatings and performance data in this publication are for acooling temperature rise of 10° F (6° C). The 30RB chillersmay be operated at a different temperature rise, providingflow limits are not exceeded and corrections to systemguidelines are made. For minimum and maximum coolerflow rates, see the Minimum and Maximum Cooler FlowRates table. A high flow rate is generally limited by themaximum pressure drop that can be tolerated by the unit.The 30RB chillers are designed for a full load temperaturerise of 5° to 20° F (2.8° to 11. 1° C). Use the PackagedChiller Builder Program to obtain the rating if a tempera-ture rise other than 10° F (6° C) is used.Minimum cooler flow (maximum cooler tempera-ture rise) — The minimum cooler flow for standard unitsis shown in Minimum and Maximum Cooler Fluid FlowRates table. When system design conditions require alower flow (or higher rise) than the minimum allowablecooler flow, follow the recommendations below.a. Multiple smaller chillers may be applied in series, each
providing a portion of the design temperature rise.b. Cooler fluid may be recirculated to raise the flow rate to
the chiller. The mixed temperature entering the coolermust be maintained to a minimum of at least 5° F(2.8° C) above the LCWT and to a maximum of nomore than 20° F (11.1° C) above the LCWT.

NOTE: Recirculation flow is shown below.
Maximum cooler flow — The maximum cooler flow(approximately 5° F [2.8° C] rise) results in a practical max-imum pressure drop through cooler.
Return fluid may bypass the cooler to keep the pressuredrop through the cooler within acceptable limits. This per-mits a higher delta T with lower fluid flow through coolerand mixing after the cooler. The mixed temperature enter-ing the cooler must be maintained to a minimum of at least5° F (2.8° C) above the LCWT and to a maximum of nomore than 20° F (11.1° C) above the LCWT.NOTE: Bypass flow is shown below.
Variable cooler flow ratesVariable flow rates may be applied to a standard chiller.The unit will, however, attempt to maintain a constantleaving chilled water temperature. In such cases, the mini-mum flow must be in excess of the minimum flow given inthe Minimum and Maximum Cooler Fluid Flow Rates table,adjusted for glycol in the system, and the minimum fluidvolume must be in excess of 3 gallons per ton (3.2 L perkW). The flow rate must change at a rate less than 10%per minute. Apply a minimum of 6 gallons per ton (6.5 Lper kW) water loop volume if the flow rate changes morerapidly.
The 30RB chiller is available without a hydronic pump-ing package or with either of 2 variations of a hydronicpumping package. One of these hydronic options offers aconstant-speed pumping package, and the other offers avariable-speed drive. Traditional pumping systems incorpo-rate constant speed drives and waste energy by relyingupon throttling valves as the only means to control flow. Amore energy-efficient approach to this issue is use a vari-able-speed drive. The 30RB chiller is now available with anoptional variable-speed hydronic package with sensorlesstechnology to meet this market requirement.
The major cost of a pump over its lifetime will be energyconsumption and maintenance, and both of these factorswill be reduced using variable-speed pumping. Energy issaved by the combination of lowering the pump speed inconjunction with the resulting lowering of pumping systemresistance when conditions permit. Maintenance benefitsfrom the sensorless pumping system include the lack of theneed to maintain remote sensors as well as the beneficialeffects of lower speed/pressure on the pump and pumpbearings.
Another advantage associated with variable-speedpumping is reduced system noise in part load operationwhen the pump is running at lower speeds. The variable-speed pump package offered on the 30RB chiller is offeredboth in single and dual-pump designs. In the dual pumpcase, in which one pump is the back-up of the other, eachpump connection is fitted with an isolation valve whichallows one pump to be isolated for service with the otherpump still operating.
As already mentioned, the 30RB variable-speedhydronic package employs sensorless technology. Theterm “sensorless” means that no remote sensors arerequired for pump operation. The sensorless pump controlmonitors system requirements from pump speed andpower. The hydronic unit is provided with a pre-definedcontrol curve to automatically adjust speed at all operatingconditions. Pump performance and characteristic curvesfor multiple speeds are programmed into the speed-con-troller memory. The pre-programmed informationincludes power, pressure and flow throughout the entirerange of the pump. During chiller operation, the powerand speed of the pump are monitored. This enables thecontroller to establish the hydraulic performance, and toposition the pump's head-flow characteristic. Although thiscurve is pre-defined, it is also fully field adjustable. Thepump has a graphical user interface, and the graphic key-pad can also be used to allow manual pump speed control.
This variable-speed pumping system easily connects toBMS (Building Management System) systems (BACnet isstandard, and LON can be obtained via special order). Thepumps may be controlled directly by the BMS system. Thesensorless feature can also be switched off to allow the useof either a 0 to 10 VDC signal or a 0 to 20 mA signal.
For multiple chiller applications employing the variable-speed pumping package, such as chillers operated in a par-allel arrangement, the drives must be connected by controlwiring and set up to run the same speed. This is to preventsurging or hunting of the speed set point. One drive willact as the master while the other slave drive will run at thesame speed. The master drive may be controlled by a 0 to10 VDC signal, a 0 to 20 mA signal, or a BMS. The drivemust be configured to not use the sensorless function inthis arrangement.
A typical example of a chiller operating with a variable-speed pumping system would be the case when the userrequires the chiller to operate with a constant fluid temper-ature difference as the load is reduced. This can be accom-plished with the 30RB variable-speed pumping packagewith the understanding that the minimum allowable flowfor the chiller must be respected. Once that limit is

reached, the flow cannot be further reduced. To accom-plish this purpose, the minimum speed of the drive is pre-set based upon the chiller size that is being employed.
As a specific example, let us say the schedule calls for a100-ton, fresh-water chiller, and it is desired to have a con-stant 10-degree temperature difference in part load opera-tion (say 54 to 44 F). The schedule calls for 240 gpm atfull load based upon the desired capacity and the fluid tem-perature difference. A constant temperature difference inpart load operation is essentially the same as providingflow in direct proportion to chiller load. In the present
example, this means that 100% load will run at the sched-uled 240 gpm, 90% load will be 216 gpm, etc. down tothe minimum allowable flow for this unit size, which, in thecase of a 30RB100, is 120 gpm. The chiller in this exam-ple will therefore be able to run down to 50% load whileapproximately maintaining a constant 10 degree fluid tem-perature difference, and then the flow will be held constantfor all lower loads. Throughout the range in which flow isreduced (down to minimum allowable flow), the pumpspeed is proportionally reduced, resulting in pump energysavings.

Fluid loop volumeThe volume in circulation must equal or exceed 3 gal. pernominal ton (3.25 L per kW) of cooling for temperaturestability and accuracy in normal air conditioning applica-tions. In process cooling applications, or for operation atambient temperature below 32 F (0° C) with low loadingconditions, there should be from 6 to 10 gal. per ton (6.5to 10.8 L per kW). To achieve this volume, it is often nec-essary to install a tank in the loop.
Tank should be baffled to ensure there is no stratificationand that water (or brine) entering tank is adequately mixedwith liquid in the tank.
The piping between the chiller and the fluid loop volumetank can be done to allow the tank to be on the return sideof the chiller (tank piped to chiller inlet) or the supply sideof the chiller (tank piped to the chiller outlet). However, it isrecommended that the tank be piped to the return side ofthe chiller to buffer any changes in load to allow more sta-ble chiller operation.
Minimum time to power chiller beforestart-upIn order to ensure that the crankcase heaters are providedsufficient time to raise the crankcase temperature to therequired operating point, power must be applied to thecontrol circuit a minimum or 24 hours prior to chiller start-up. On 30RB chillers, the control circuit obtains its powervia a control transformer off the main 3-phase power sup-ply. Therefore, the main (3-phase) power is to be suppliedat least 24 hours prior to chiller start-up unless there arespecial means for providing control power.
Cooler fouling factorThe fouling factor used to calculate tabulated ratings is0.00010 ft2 � hr � °F/Btu (0.000018 m2 � °C/W). As foul-ing factor is increased, unit capacity decreases and com-pressor power increases. Corrections to published ratingscan be approximated by using the multipliers in the foulingfactors table.
FOULING FACTORS
Cooler and hydronic system freeze protectionFreeze protection for down to –20 F (–28.9 C) for thecooler and hydronic package is available as a factory-installed option. Since power is sometimes lost for extend-ed periods during winter storms, freeze protection provid-ed by heater tapes will be effective only if a back-up powersupply can be assured for the unit’s control circuit, heaterand cooler pump. If not protected with an antifreeze solu-tion, draining the cooler and outdoor piping is recom-mended if the system will not be used during freezingweather conditions.
Two conditions that must be considered when determin-ing antifreeze concentration are leaving water set pointand ambient freeze conditions. Both of these parameterscan help determine the recommended concentration level.Higher concentration must be used to adequately protectthe machine.NOTE: Use only antifreeze solutions approved for heat ex-changer duty.
For applications in which the leaving water temperatureset point is less than 40 F (4.4 C), a suitable inhibited anti-freeze solution must be used. The solution concentrationmust be sufficient to protect the chilled water loop to afreeze protection (first crystals) concentration of at least15° F (8.3º C) below the leaving water temperature setpoint.
If the chiller refrigerant or fluid lines are in an area whereambient conditions fall below 34 F (1º C), it is required thatan antifreeze solution be added to protect the unit and fluidpiping to a temperature of 15º F (8.3º C) below the lowestanticipated ambient temperature.
Select concentration based on either burst or freeze pro-tection as dictated by the application. If the chiller does notoperate during the winter, nor is a start-up expected, aburst protection concentration is recommended. This con-centration may not be high enough to pump the fluidthrough the unit. Burst protection is typically a lower con-centration that will provide better performance from themachine. If the chiller does operate during winter, a freezeprotection concentration is recommended. This concentra-tion will be high enough to keep the fluid in a conditionthat it can be pumped at low ambient conditions.
Consult glycol fluid manufacturers for burst protectionrecommendations and fluid specifications.
IMPORTANT: Glycol anti-freeze solutions are highlyrecommended since heater tapes provide no protec-tion in the event of a power failure.

High ambient temperature operationHigh outdoor ambient chiller start-up and operation is pos-sible for standard 30RB chillers at ambient temperaturesup to 125 F (52 C) at nominal voltage. In some cases,where return water temperature is expected to exceed60 F (15.5 C), an accessory kit may be required.
Low ambient temperature operationUnits will start and operate down to 32 F (0° C) asstandard.NOTE: Minimum load on chiller must be above the mini-mum step of unloading.
Operation to –20 F (–29 C) requires optional low ambi-ent head pressure control on the 30RB unit (no low ambi-ent head pressure control is required with the 30RB chillerwith Greenspeed® technology) as well as wind baffles (fieldfabricated and installed to all units for operation below 32F [0° C]) if wind velocity is anticipated to be greater than5 mph (8 km/h). Inhibited propylene glycol or other suit-able corrosion-resistant anti-freeze solution must be fieldsupplied and installed in all units for unit operation below34 F (1° C). Solution must be added to fluid loop to protectloop down to 15° F (8° C) below minimum operating ambi-ent temperature. Concentration should be based onexpected minimum temperature and either “Burst” or“Freeze” protection levels. At least 6 gal per ton (6.5 L perkW) of fluid volume is the recommended minimum for amoderate system load.
High-efficiency variable condenser fansHighly efficient part load performance is available withvariable speed condenser fan motors controlled by variablespeed drives. In most applications, the chiller will run atpart load conditions the vast majority of the time, and thisis particularly the case if the application has a 24/7 dutycycle. This option will lower utility costs while producing ascroll compressor design that is best-in-class in part loadefficiency. This is the essence of 30RB chillers withGreenspeed® technology. (High-efficiency variable con-denser fans are not available with sizes 060 and 070.)

ALTITUDE CORRECTION FACTORS
Condenser airflowAirflow restrictions on units with standard fans will affectthe unit capacity, condenser head pressure, and compres-sor power input. Correction factors to be applied for

Condenser coil protection (Enviro-Shield™)Refer to the environmental selection guides for more infor-mation. If the standard Novation® (microchannel) coil doesnot meet the corrosion requirements for a given applica-tion, additional coil options are available. For specific geo-graphical recommendations, please refer to the NACO(North American Commercial Operations) PackagedChiller Builder program.Aluminum fin/copper tube coils are constructed ofseamless copper tubes mechanically bonded to aluminumfins. The fins have wavy enhancements. These condensercoils are recommended with remote cooler applications.These coils are not recommended for corrosive environ-ments.Pre-coated aluminum-fin coils have a durable epoxy-phenolic coating applied to the fin prior to the fin stampingprocess to provide protection in mildly corrosive coastalenvironments. Pre-coated coils have an inert barrierbetween the aluminum fin and copper tube. This barrierelectrically disconnects the dissimilar metals to minimizethe potential for galvanic corrosion. This economicaloption provides substantial corrosion protection beyondthe standard uncoated coil construction.Copper-fin coils provide increased corrosion resistancecompared to aluminum fin coils. All-copper coils eliminatebimetallic construction to eliminate the potential for gal-vanic corrosion. Application in industrial environments isnot recommended due to potential attack from sulfur, sul-fur oxide, nitrogen oxides, carbon and several other indus-trial airborne contaminants.E-coated Novation® coils have an extremely flexibleand durable epoxy coating uniformly applied to all coil sur-faces. Unlike brittle phenolic dip and bake coatings, e-coatprovides superior protection with unmatched flexibility,edge coverage, metal adhesion, thermal performance andmost importantly, corrosion resistance. E-coated coilsprovide this protection since all coil surfaces are complete-ly encapsulated from environmental contamination. Thisoption provides the best protection for Novation coiltechnology.E-coated aluminum-fin coils have the same flexible anddurable epoxy coating as e-coated Novation coils. This op-tion provides better protection compared to standard orpre-coated aluminum-fin coils in many environments.E-coated copper-fin coils have the same flexible anddurable epoxy coating as other e-coated coils. However,this option combines the natural salt and environmental re-sistance of all-copper construction with the highest level ofcorrosion protection within the round-tube, plate-fin typeof coils.
Electrical/utility interestsUse of energy management practices can significantlyreduce operating costs, especially during off-peak modesof operation. Demand limiting and temperature reset are 2techniques for accomplishing efficient energy manage-ment. See Demand Limiting (also called load shedding) sec-tion below for further details.
Demand limiting (load shedding)When a utility’s demand for electricity exceeds a certainlevel, loads are shed to keep electricity demand below aprescribed maximum level. Typically, this happens on hotdays when air conditioning is most needed. The energymanagement module (EMM) can be added to accomplishthis reduction. Demand may be limited on unit by resettingfluid temperature, or by unloading the chiller to a givenpredetermined percentage of the load. Demand limit mayalso be driven by an external 4 to 20 mA signal. These fea-tures require a signal from an intelligent central control. Donot cycle demand limiter for less than 10 minutes on and5 minutes off. Duty cycling cycles electrical loads at regularintervals regardless of need. This reduces the electricaloperating costs of building by “fooling” demand indicatingdevices. Duty cycling of compressors or fans is not recom-mended since motor winding and bearing life will sufferfrom constant cycling.
Remote on-off controlRemote on-off control may be applied by hard-wired con-nection (see Controls and Troubleshooting literature) or byconnection to a Carrier Comfort Network® (CCN) system.
Optional hydronic system selectionSelect pump gpm from resulting chiller selection and totalpressure loss in the system plus the chiller internal pressureloss.NOTE: Maximum gpm (L/s), pressure and pump hp mustnot exceed maximum on pump curve.NOTE: Optional hydronic system is available in bothconstant-speed and VFD configurations, as described inthe Variable Cooler Flow Rates section.
Pump flow can be reduced by using the factory-suppliedtriple-duty valve up to 10%. Beyond that, impeller
trimming is recommended to reduce energy consumption.Follow local codes or ASHRAE 90.1 recommendations.Contact your Carrier representative for specific amount oftrim required.
The AquaSnap® 30RB chiller will require a field-supplied expansion tank when the optional pumping pack-age is provided.
The expansion tank is based on fluid type, temperaturerange, fluid pressure and loop volume.
Parallel chillers with hydronic packages require thatpump inlets be equalized to prevent pump cavitation.Pump expansion tanks must be removed and locatedtogether in the common pump suction header. All materi-als needed for expansion tank relocation are field supplied.Appropriate measures must be taken for freeze protection.NOTE: The hydronic package is not available on unitsequipped with the heat reclaim option.
Air separationThe AquaSnap 30RB chiller will require a field-supplied airseparation device when the optional pumping package isprovided.
Air must be controlled in a hydronic system if it is to per-form properly. Air can block the flow of chilled water to itsdestinations and can cause cavitation in the pump, whichwill aerate the pump and potentially cause pump failure.The air separator is sized according to the total flowthrough the system. The air separator should be locatedinside the building. There are several types of air separa-tors to choose from.

Heat reclaimWhenever a chiller is operating, the heat removed from thecooler fluid as well as the energy associated with the com-pression process must be moved to another location.Under standard operation, an air-cooled chiller moves andreleases this heat to the atmosphere. There are times,however, when it is beneficial to capture this heat and con-vert it into useful hot water. The heat reclaim option has been developed to serve thispurpose. Unlike many heat reclaim schemes seen on the

market, the heat reclaim option that has been developedfor the 30RB is full condensing. This means that thiswater-cooled condenser, which is in parallel with thestandard air-cooled condenser, is capable of capturing all ofthe heat available from the chiller condensing process. Theleaving water temperature can reach at maximum 131 F(55 C) under steady state and constant hot water flow con-ditions with an allowable hot water temperature rangefrom 68 to 131 F (20 to 55 C). To operate in the heat reclaim mode, there must be asimultaneous need for chilled water and tempered hotwater. Just as the chiller operates in standard duty, thechiller always controls the leaving chilled water tempera-ture. Consequently, the chiller will produce as much hotwater as possible while maintaining the leaving chilledwater temperature. To generate hot water, the entering hot water tempera-ture is compared to the hot water set point to determinethe number of circuits necessary to maintain the enteringhot water temperature. If the entering hot water tempera-ture is below the customer-adjustable set point, one refrig-eration circuit will automatically be changed over to theheat recovery mode to produce tempered hot water. In thismode, the chiller is operating as a water-cooled chiller withone circuit and as an air-cooled chiller with the othercircuit. Depending on the entering hot water requirements, thesecond circuit may also be switched to the heat recoverymode through the integrated controls. The entering hotwater temperature is controlled by the cycling of eachrefrigerant circuit from the cooling-only to the heat recov-ery modes. When the hot water set point is satisfied, thechiller will transition back to the cooling-only mode as aconventional air-cooled chiller. The number of cycles is lim-ited to 4 per hour. The leaving hot-water temperature is a function of theentering hot water temperature, hot water flow and chillercapacity. In the heat reclaim mode, the entering hot watertemperature, and not the leaving hot water temperature, iscontrolled. As a consequence, these applications are usefulfor make-up water or preheating of process hot watersystems that have alternative means of controlling thedesired hot-water temperature.Energy efficiency — When the heat reclaim chiller issimultaneously producing hot water and satisfying the cool-ing load, the overall total COP will be very high. As anexample of the benefits of a heat reclaim chiller with regardto total COP, if we look the performance of a nominal110 ton air-cooled chiller with heat reclaim we can see theenergy advantages based on the total COP.Chiller Performance at AHRI Conditions with HeatReclaim (104 F/114 F) in Operation:Cooling Capacity 96.3 tons (339.0 kW)Input Power 121.0 kWHeating Output 1,548 MBH (453 kW) 453 kW + 339 kW 121.0 kWCOP (TOTAL) = 6.5
Head pressure control — A form of head pressure con-trol is required while in the heat reclaim mode. In order tomeet this requirement, a 3-way control valve must be field-installed. Since the hot water temperature at start-up maybe very low, the 3-way valve is to be located as close to theheating condenser as possible so that this valve can quicklyaccomplish its purpose of maintaining the minimumrequired head pressure. In this regard, the 3-way valve is tobe located with 40 ft (12.2 m) of the heating condenser. The 30RB chiller uses an analog output to control thisvalve. See figure below. A minimum loop volume of 6 gal-lons per ton of heating (0.5 to 0.83 gallons [1.9 to 3.1 L]per MBH of heating) capacity is necessary. In some cases,this will require the installation of a hot-water buffer tank.
NOTE: Locate the 3-way valve as close as possible to thechiller to minimize head pressure control response time.Operating limits — With a properly installed 3-waywater valve, the minimum hot-water inlet temperature canbe as low as 40 F (4 C) during system start-up. The hotwater flow range is from 2 to 4 gpm per heating ton(0.13 to 0.25 L per minute). See the Heat Recovery Oper-ation Envelope tables on page 87 for the allowable rangeof chiller operating conditions when the heat reclaimoption has been selected.Freeze protection — The heat reclaim condenser is lo-cated within the standard chiller envelope. Therefore, thisdevice, as well as its associated water piping, must be locat-ed outdoors. A form of freeze protection must be provided.The heating condenser is provided with a heater that willaccomplish freeze protection down to 0° F (–17.8 C). If aunit controls the water pump/valves, allowing for flowthrough the condenser, the unit is protected from freezingdown to –20 F (–28.9 C). In addition, the same guidelinefor cooler freeze protection and preparation for wintershutdown must be followed. The Carrier warranty does notcover damage due to freezing. The piping, however, musteither be provided with heat trace or an antifreeze solutionmust be added to the hot water fluid. Adding antifreeze solution is the only certain means ofprotecting the unit from freeze-up if the heater fails or elec-trical power is interrupted or lost while temperatures arebelow 32 F (0° C).
