INTRODUCTIONZamil Air cooled scroll chillers (ALY series) are the heart of most central Air Conditioning systems for medium sizebuildings. They consist of one or more hermetic scroll compressors, air-cooled condenser coils with condenser fan(s) andmotor(s), insulated liquid cooler, expansion device, interconnecting refrigerant piping, oil & refrigerant charge, control panel,wiring and other auxiliaries.
ALY series, The new generation of air cooled packaged liquid chillers.
ALY series air cooled scroll chillers are available in capacity range 10 TR (35 kW) to 120 TR (422 kW) at AHRI conditions,in one single enclosure, utilizing refrigerant R-410A as working fluid with option of three different power supply ratings.
ALY series chillers have been designed and manufactured to meet the requirements of the Gulf’s severe climatic condi-tions and specifically for outdoor installation, on roofs or ground level. They are factory assembled, leak tested, evacuated,internally wired, fully charged with refrigerant. Each ALY chiller is fully factory tested before delivery and is ready forinstallation. All what required on site is to connect chilled water pipes and main power supply.
Scroll Compressor:The scroll compressor consists of two involutes or Archimedean spirals (Figure-1). One spiral is positioned inside the otherto form a series of recent-shaped pockets. During compression the upper spiral remains stationary and the lower one, beingeccentrically mounted on the drive shaft, describes an orbital rather than a simple rotary motion.
3
How a Scroll Compressor works:
Compression in the scroll is created by the interaction of an orbiting spiral and a stationaryspiral. A refrigerant enters the outer openings as one of the spirals orbits.
The open passages are sealed off as gas is drawn into the spiral.
As the spiral continues to orbit, the gas is compressed into two increasingly smaller pockets.
By the time the gas arrives at the center port, discharge pressure has been reached.
Actually, during operation, all six gas passages are in various stages of compression at alltimes, resulting in nearly continuous suction and discharge.
4
FIGURE- 1
Refrigerant enters the compressor at the suction connection and flows around the motor’s housing and enters at thebottom side through the openings.
Oil droplets separate from the refrigerant and fall into the oil sump.
All suction refrigerant passes through the electrical motor, ensuring full motor cooling.
After that the refrigerant enters the scroll elements.
COOLERSThe DX shell and tube cooler with removable ‘U’ shaped bundled tubes are made of internally grooved copper tubesexpanded into heavy steel tubular sheets. The cooler housing and baffles are constructed of steel and brass respectively.All coolers are fitted with vent, drain connection and water pipe connections as below:
1. Male pipe thread (MPT) connection for the models ALY010D - ALY060D.
2. Victaulic connection for the models ALY075D - ALY120D.
The coolers are insulated with heavy closed cellular foam insulation (3/4” thick).

Tandem Compressor:Models ALY020D to ALY120D use tandem scroll compressors. Tandem scroll compressors make possible great flexibilityin system design for a wide range of applications. Since each compressor may be operated individually, this designprovides simple, capacity reduction & maximum power savings and greatly simplifies system control. In any well designedsystem, this kind of design offers a much greater factor of redundancy than a single compressor and provides emergencyprotection for the product. In addition to greater reliability, one great advantage of the multiple compressor design over otherlarge horsepower compressors is the fact that in the event of compressor damage, replacement of either compressor in thetandem can be easily done.
FEATURESThese ALY series, packaged air cooled water chillers are designed to provide engineering excellence in comfort air condi-tioning and industrial cooling with a superior combination of energy saving, performance, application flexibility, ease ofservice & maintenance and withstanding extremely high ambient temperatures. These chillers incorporate a wide range offeatures including:
* Microprocessor controller, which monitors analog and digital inputs to achieve precise control & protective functions ofthe air cooled water chiller units. The microprocessor controller is complete with all the hardware and software neces-sary to control the chiller unit and ensures its efficiency and reliability.
* Compact unit design and open base design provides easy access and service to the major components and accesso-ries.
* High Energy Efficiency Ratio (EER) hermetic scroll compressors.
* Single point power connection to minimize job site installation cost and time.
* Completely wired control panel with the advanced microprocessor controller that provides all the necessary operationsand safety controls.
* Made ready connection for remote ON/OFF switch and General Alarm output.
* Compressor connections are Direct On Line (DOL) for all models (see electrical data).
* Low noise condenser fans, direct drive with rolled form venturi design to eliminate airflow recycling & short circuiting.
* Condenser fans are die-cast aluminum aerodynamic design, top discharge & provided with protective grille mounted ontop panel within the unit casing.
* All condenser fan motors are totally enclosed air over type (TEAO) with class ''F'' winding insulation.
CAPACITY CONTROLThe Zamil air cooled scroll water chillers incorporate stepped load shedding as required by most energy managementsystems. Modulation of capacity in response to system load requirements is affected by the microprocessor controllerwhich monitors the leaving water temperature.
Capacity control is achieved by cycling compressors ON/OFF and sequential operation of compressors which providesoptimal part load capacities for chillers with multiple compressors.See the following table for the standard and optional capacity control for each unit.

NOTES: 1. All compressors operate at 3500 RPM @ 60Hz.2. Sound pressure level : ±2dBA.
DESIGN REQUIREMENTSThe following design requirements must be known to select a package chiller.1. Required cooling capacity in tons2. Leaving chilled water temperature in 0F (LCWT)3. Chilled water flow rate in GPM4. Chilled water cooling range in 0F (water in temp. _ water out temp.)5. Design ambient temperature6. Minimum ambient temperature7. Altitude8. Electrical power supply
SAMPLE SELECTIONSelect an Air Cooled Packaged chiller for the following conditions:Required system capacity is 33 tons at 540F entering chilled waterand 440F leaving water. Design ambient temperature is 950F.Altitude is 2000 feet above sea level.Water cooler fouling factor is 0.00010. Power supply: 380V-3Ph-60Hz.
STEP-1: UNIT SELECTIONEntering the capacity performance data at given LCWT and ambient temperature.ALY035 chiller unit at sea level will produce 36.7 tons and 34.5 kW compressorpower input at 440F leaving chilled water temperature with 100F water temperaturedifference and 950F ambient temperature.
For the conditions required, the unit actual cooling capacity when corrected foraltitude (0.99) and fouling factor (1.0).Capacity = 36.7x0.99x1.0 = 36.3 Tons, which then exceeds the requirements.So the selection is correct.
STEP-2: CHILLED WATER FLOW (GPM):
Water GPM = Required capacity (Tons) x 24
= 33 x 24
= 79.2 GPM Cooling Range, ΔT 100F

Referring to pressure drop chart (page # 19), pressure drop at 79.2 GPM = 15.3 ft. of water for selected model.
STEP-3: ELECTRICALRefer to electrical data at 380V-3Ph-60Hz, the main power wire size for ALY035 is to be sized at a minimum circuitampacity (MCA) of 117 Amps and the main branch protection device is to be sized at a maximum over current protection(MOCP) of 175 Amps.
STEP-4: CHILLED WATER PUMP SELECTIONFor chilled water pump selection, add all pressure drop in the closed chilled water loop piping to the pressure drop calcu-lated in step 2.
STEP-5: LCWT CORRECTIONRefer to table-3: Add correction factor to design leaving chilled water temperature (LCWT) when chilled water tempera-ture range is above 100F and subtract correction from design leaving chilled water temperature (LCWT) when watertemperature range is below 100F.EXAMPLE:If LCWT rise is 12.50F, enter correction curve at 12.50F and read the correction factor of 0.2. The corrected LCWT is44+0.2 = 44.20F.
NOTE: 1. When the chilled water temperature rise is less than 80F, the high water flow rate will result to excessive pressuredrop. In such cases, contact factory for special selection of a cooler with wider baffle spacing.
2. Please refer to water pressure drop curves.

MICROPROCESSOR CONTROLLERCONTROLLER SEQUENCE OF OPERATIONFor initial start-up, the following condition must be met:
• All power supplied to the unit shall be continuously energized for 12 hours.
• All safety conditions are satisfied.
• Chilled water pump is running normal and chilled water flow switch contact is closed.
• Customer control or remote ON/OFF is switch to run mode, if any.
Staging ON and OFF sequence is accomplished based on controlled water temperature. The controller works to maintainthe required demand as constant as possible.
Below sequence of operation belongs to chiller unit with 2 scroll compressors. For 4, 6 & 8 scroll compressors chiller unitthe operation will be the same. Only that the capacity changes depend on the quantity of the compressor. For single scrollcompressor unit the capacity change to 100%.
COMPRESSOR STAGE - ON SEQUENCEIf the water temperature is above the temperature set point: The compressor with less running hours will start, and theunit is now at the 50% capacity. After such interval of time, and if the water temperature is still high compared to thetemperature set point, the second compressor will start. The unit now is at 100% capacity.
COMPRESSOR STAGE - OFF SEQUENCEAssume that the 2 compressors are running (capacity is at 100%). After such interval of time, if the water temperature isdecreases or below the temperature set point the compressor with more running hours will off. Now the unit is at 50%capacity. After such interval of time, if water temperature still below the set point temperature, then second compressorwill off.
FAN - ON/OFFThe fan will switch ON & OFF together with the compressor ON and OFF operation respectively.

APPLICATION GUIDELINESINTRODUCTIONThese guidelines should be considered when designing systems and their installation utilizing Zamil ALY series liquidchillers. Stable operation, performance and reliability of units is often dependent upon proper compliance with theserecommendations. When any application varies from these guidelines, it should be referred with Zamil Air Conditionersfor specific recommendations.
UNIT SELECTION/SIZINGUnit selection procedure and capacities are provided in this catalog for proper selection. The Zamil electronic selectionprogram may also be utilized for this purpose.
Over sizing chillers beyond a maximum limit of 5 – 10 % in order to assure adequate capacity or considering futureexpansions is not recommended. Over sizing adversely affects the operating efficiency due to erratic system operationand excessive compressor cycling which also results in reduced compressor life. It should be noted that, units operatemore efficiently when fully loaded rather than larger equipment operating at partial capacities. In addition, an oversizedunit is usually more costly to purchase, install and operate.
FOULING FACTOR AND WATER REQUIREMENTThe tabulated performance data provided in this catalog are based on a fouling factor of 0.00010 hr-ft2-0F/Btu (0.000018 m2-0C/W).As fouling factor is increased, unit capacity decreases and power input increases. For unit selection at other foulingfactors, apply appropriate correction factor from the table provided in this catalog.
These chillers are suitable for operation with well maintained water systems. Using unclean and untreated water mayresult in scale and deposit formation causing reduced cooler efficiency or heat transfer and corrosion or pitting leading topossible equipment damage.
EFFECT OF ALTITUDE ON UNIT CAPACITYThe tabulated performance data provided in this catalog are for use at or near sea level altitude application. At altitudessubstantially above sea level, the decreased air density will reduce condenser capacity and therefore unit capacity. For unitselection at these higher altitudes, apply appropriate correction factor from the table provided in this catalog.
HIGH AMBIENT CONSIDERATIONThese chillers are designed for year round operation over a range of ambient temperatures. As a standard, these chillerscan start and operate satisfactorily up to 1250F (520C) ambient temperature at rated nominal voltage.
WATER FLOW RATES AND COOLER PRESSURE DROPThe maximum and minimum water flow rates for all unit models and the pressure drop chart are provided in this catalog.The design water flow rate must be within this range. Design flow rates below the minimum limits will result in laminarflow causing freeze-up problems, stratification and poor control and flow rates beyond the maximum limits cause exces-sive pressure drop and severe tube erosion.
During unit operation, water flow rate must not vary more than ± 5% from the design flow rate. The water flow switch should becalibrated accordingly.
COOLER FLUID (WATER OR GLYCOL) TEMPERATURES RANGEUnit can start and pull down from 950F (350C) entering fluid temperature. The design leaving chilled fluid temperature(LCWT) range as mentioned earlier in the tabulated performance data is 40 to 500F. The design entering chilled fluidtemperature range is 50 to 600F. The design cooler temperature drop (ΔT) range is 8 to 150F.
The tabulated performance data provided in this catalog is based on a chilled water temperature drop of 100F. Units maybe operated at any desired temperature drop within the range of 8 to 150F as long as the temperature and flow limits are notviolated and appropriate correction factors are applied on the capacity and power input. The Zamil electronic selectionprogram can be very handy in selecting equipment at different temperature drops.
It should be noted that temperature drop outside the aforesaid range is not permitted as it is beyond the optimum range of controland could adversely affect the functioning of microprocessor controller and may also prove to be detrimental for the equipment.
30
COOLER FREEZE PROTECTIONIf the unit is located in an area where ambient temperatures fall below 320F (00C), cooler protection in the form of EthyleneGlycol Solution is required to protect the cooler and fluid piping from low ambient freeze-up. This glycol solution must beadded to the water system loop to bring down the freezing point of water to a difference of 150F (8.30C) below minimumoperating ambient temperature.
Using this glycol solution causes a variation in unit performance, flow rate and pressure drop, therefore appropriatecorrection factors from the aforementioned table in this catalog should be applied.
MULTIPLE CHILLER ARRANGEMENT OR PLANT CONFIGURATIONA multiple chiller system has two or more chillers connected by parallel or series piping to a common distribution system.Multiple chiller arrangements offer the advantage of operational flexibility, standby capacity and less disruptive mainte-nance. Also, they offer some standby capacity if repair work must be done on a chiller from a set of duty chillers. Startingin-rush current is reduced, as well as power costs at partial-load conditions.
A multiple chiller arrangement should be provided if the system load is greater than a single chiller capacity, standbycapability is desired, large temperature drop (greater than 150F) is desired or application calls for splitting the totalcapacity for better part load operation.
In designing a multiple chiller plant, units of same size should be preferred over different sizes to facilitate balanced waterflow. It is mandatory that cooler flow rates must be balanced to ensure proper flow to each chiller based on its respectivecapacity. As mentioned above, two basic multiple chiller systems are used: parallel and series chilled water flow.
Zamil recommends the parallel arrangement for design temperature drops (ΔT) up to 150F and the series arrangementbeyond that i.e., 16 to 200F. Complete design details on these parallel and series chilled water flow arrangements can befound in the ASHRAE handbooks and other design literature which should be referred by the designer in preparing hisdetailed designs.
PIPING ARRANGEMENTS AND PLANT LAYOUTOur chillers are suitable for incorporating in ‘Two Pipe’ single temperature systems or ‘Four Pipe’ independent loadsystems. The system piping circuit (load distribution circuit) should be basically parallel piping either Direct Return orReverse Return system with a good pumping arrangement.
The method of circuiting and pumping is a judgment decision by the designer. The designer must weigh the pros andcons of cost, nature of load and configuration of building, energy economics, flexibility, installation requirements andothers to determine the best arrangement for his project. In all cases, it must be ensured that the design water flow isconstantly maintained through the chillers at all stages of operation.
UNIT LOCATION AND INSTALLATIONThese chillers are designed for outdoor installation and can be installed at ground level or on a suitable rooftop location.In order to achieve good operation, performance and trouble-free service, it is essential that the proposed installationlocation and subsequent installing procedures meet the following requirements:
• The most important consideration while deciding upon the location of air cooled chillers is the provision for supply ofadequate ambient air to the condenser and removal of heated discharge air from the condenser. This is accomplishedby maintaining sufficient clearances which have been specified in this Catalog around the units and avoiding obstruc-tions in the condenser air discharge area to prevent the possibility of warm air circulation. Further, the condenser fansare propeller type and are not recommended for use with ductwork or other hindrances in the condenser air stream.Where these requirements are not complied, the supply or discharge airflow restrictions or warm air recirculation willcause higher condensing temperatures resulting in poor unit operation, higher power consumption and possible even-tual failure of equipment.
31
• The unit’s longitudinal axis should be parallel to the prevailing wind direction in order to ensure a balanced air flowthrough the condenser coils. Consideration should also be given to the possibility of down-drafts caused by adjacentbuildings, which may cause recirculation or uneven unit airflow. For locations where significant cross winds are ex-pected, an enclosure of solid or louver type is recommended to prevent wind turbulence interfering with the unit airflow.When units are installed in an enclosure, the enclosure height should not exceed the height of the unit.
• The location should be selected for minimum sun exposure and away from hot air sources, steam, exhaust vents andsources of airborne chemicals that could attack the condenser coils and steel parts of the unit. Avoid locations wherethe sound output and air discharge from the units may be objectionable.
• If the location is an area which is accessible to unauthorized persons, steps must be taken to prevent access to the unitby means of a protective fence. This will help to prevent the possibility of vandalism, accidental damage or possibleharm caused by unauthorized removal of panels or protective guards exposing rotating or high voltage components.
• The unit must be installed on a ONE-PIECE, FLAT and LEVELLED {within 1/2'' (13 mm) over its length and width} /CONCRETE BASE that extends fully to support the unit. The carrying or supporting structure should be capable ofhandling complete operating weight of the unit as given in the Physical Data tables in this Catalog.
• For ground level installations, it must be ensured that the concrete base is stable and does not settle or dislocate uponinstallation of the unit which can strain the refrigerant lines resulting in leaks and may also cause compressor oil returnproblems. It is recommended that the concrete slab is provided with appropriate footings. The slab should not beconnected to the main building foundation to avoid noise and vibration transmission.
• For rooftop installations, choose a place with adequate structural strength to safely support the entire operating weightof the unit. The unit shall be mounted on a concrete slab similar to ground installations. The roof must be reinforced forsupporting the individual point loads at the mounting isolator locations. It must be checked and ensured that theconcrete base is perfectly horizontal and levelled, especially if the roof has been pitched to aid in water removal. Itshould be determined prior to installation if any special treatment is required to assure a levelled installation else itcould lead to the above mentioned problems.
• Vibration isolators are necessary for installing these chillers in order to minimize the transmission of vibrations. Thetwo types of vibration isolators generally utilized for mounting these units are Neoprene Pads and Spring Isolators.Neoprene Pads are recommended for ground level normal installations jobs where vibration isolation is not critical andjob costs must be kept to a minimum. Spring Isolators are recommended for ground level installations which are noise-sensitive areas or exposed to wind loads and all roof top installations. For critical installations (extremely noise andvibration sensitive areas), follow the recommendations of structural and acoustical consultants.
• Based on the specific project requirements, choose the type of vibration isolators best suited for the application.Carefully select the vibration isolators’ models / configuration based on the respective point loads and place eachmount in its correct position following the Load Distribution Data and Mounting Drawings provided in this Catalog.Refer to the Schematic Mounting Layout drawings provided in the IOM manual of these chillers for further details in thisregard.
COOLER PIPING CONNECTIONSThe following pertinent guidelines are served to ensure satisfactory operation of the units. Failure to follow these recom-mendations may cause improper operation and loss of performance, damage to the unit and difficulty in servicing andmaintenance:
• Water piping must be connected correctly to the unit i.e., water must enter from the inlet connection on the cooler andleave from the outlet connection.
• A flow switch must be installed in the field piping at the outlet of the cooler (in horizontal piping) and wired back to theunit control panel using shielded cable. There should be a straight run of piping of at least five pipe diameters on eitherside of the flow switch. Paddle type flow switches can be obtained from Zamil which are supplied as optional items.
• The chilled water pump(s) installed in the piping system should discharge directly into the unit cooler. The pump(s)may be controlled external to the unit - but an interlock must be wired to the unit control panel (as shown in the wiringdiagram) so that the unit can start only upon proof of pump operation.
32
• Flexible connections suitably selected for the fluid and pressure involved should be provided as mandatory in order tominimize transmission of vibrations to the piping / building as some movement of the unit can be expected duringnormal operation. The piping and fittings must be separately supported to prevent any loading on the cooler.
• The cooler must be protected by a strainer, preferably of 20 mesh, fitted as close as possible to the liquid inlet connec-tion, and provided with a means of local isolation.
• Thermometer and pressure gauge connections should be provided on the inlet and outlet connections of each cooler.Pressure gauges are recommended to check the water pressure before and after the cooler and to determine if anyvariations occur in the cooler and system. When installing pressure taps to measure the amount of pressure dropacross the water side of the cooler, the taps should be located in the water piping a minimum of 24 inches downstreamfrom any connection (flange etc.) but as near to the cooler as possible.
• Drain and air vent connections should be provided at all low and high points in the piping system to permit completedrainage of the cooler and piping as well as to vent any air in the pipes. Hand shut-off valves are recommended for usein all lines to facilitate servicing.
• The system water piping must be flushed thoroughly before connecting to the unit cooler. The cooler must not beexposed to flushing velocities or debris released during flushing. It is recommended that a suitably sized bypass andvalve arrangement is installed to allow flushing of the piping system. The bypass can be used during maintenance toisolate the cooler without disrupting flow to other units.
• The following is a suggested piping arrangement at the chiller for single unit installations. For multiple chiller installa-tions, each unit should be piped as shown:

CHILLED FLUID VOLUME REQUIREMENTThe volume of water in a piping system loop is critical to the smooth and proper operation of a chilled water system. Ifsufficient volume of water is not there in the system, the temperature control can be lost resulting in erratic systemoperation and excessive compressor cycling. Therefore, to prevent this effect of a ‘Short Water Loop’ ensure that totalvolume of water in the piping system loop equals or exceeds 3 Gallons per Nominal Ton of cooling capacity for standardair conditioning applications and 6 Gallons per Nominal Ton of cooling capacity for process cooling jobs where accuracyis vital and applications requiring operation at very low ambient temperatures and low loading conditions.
For example, chiller model ALY080 operating with a design water flow rate of 180 GPM for a standard air conditioningapplication would require 80 (Nom. Cap.) x 3 = 240 Gallons of water in the piping system loop.
To achieve the aforementioned water volume requirements, it may be necessary to install a tank in the piping system loopto increase the volume of water in the system and therefore, reduce the rate of change of return water temperature. Thistank should be provided on the return water side to the chiller and the tank should be baffled to ensure that there is nostratification and the entering stream thoroughly mixes with the tank water. See recommended tank design schematicsbelow:

LIFT
ATTENTION TO RIGGERSHook rigging sling thru holes on the lifting plates, as shown below.Lifting plates or holes in base rail are centered around the unit center of gravity.Center of gravity is not unit center line.Ensure center of gravity aligns with the main lifting point before lifting.Use spreader bar when rigging, to prevent the slings from damaging the unit.
CAUTIONAll panels should be in place when rigging.Care must be taken to avoid damage to the coils during handling.Insert packing material between coils & slings as necessary.
