YORK INTERNATIONAL 3

General Description

UNIT DESCRIPTION

The YORK CurbPak is designed for rooftop applications.The design flexibility and quality construction of theCurbPak sets it apart from the competition.

OUTDOOR FEATURES

The CurbPak is specifically designed for outdoor appli-cations. The outdoor design features of the CurbPakallow it to withstand the most severe environments.

A rooftop unit is only as good as its roof. The CurbPakroof is sloped to eliminate standing water and its corro-sive effects. In addition, the roof panels are fastenedthrough standing seams and attached to the side walls.This eliminates the need for any screws through theskin of the roof, thus eliminating this as a possible sourceof leakage.

On the YORK CurbPak, the roof overhangs the side-walls and doors, allowing runoff water to drop freely,eliminating corrosive “streaming” down the sides of theunit.

The sidewalls are also free of exposed holes, and jointsare caulked and covered with U-shaped seamcaps toassure a tight, reliable seal. Internal stiffening assuresa high resistance to wind loads.

All outside air and exhaust air openings are protectedfrom the outside elements by rain hoods. The rain hoodsassure that no wind-blown moisture can penetrate theunit casing. The rain hood design features a full-length,drip lip that prevents moisture from being drawn in theoutside air intake.

The CurbPak coil IAQ drain pan is sloped to minimizestanding condensate, and offers a full two inches of in-sulation to give the pan the thermal protection it requires.

STRUCTURAL PERFORMANCE

The CurbPak housing has been designed for maximumdeflections 1/200 of panel length. Design criteria sys-tem static pressure include snow loading of 30 pound/sq. ft. and wind load of 100 m.p.h.

QUALITY

CurbPak units are constructed entirely of double wallpanels – including the floor panels! Panels are insulatedwith a full two inches of insulation. Perforated lining isavailable in most segments to meet a variety of appli-cations.

The double wall design provides the highest quality ofunit construction, while preventing erosion of the insu-lation fibers into the air stream.

Access Doors

The CurbPak access doors are also double wall con-struction. The doors feature a full-length stainless steelpiano hinge. The use of positive action handles preventlocking if door is accidentally shut. These handles areused in unit sizes 65 through 400. For walk-in unit sizes460 through 1030, all door latches have a single handlewith multiple latch points.

FLEXIBILITY

For maximum flexibility the CurbPak is based on a seg-mented design concept. The unit construction however,is unitized. Each unit is engineered and built as a singleassembly for greater unit integrity.

The segmental design concept permits the designer tooptimize and customize segments that will best meetthe application. The unit is then engineered and built asa single piece, not a collection of pre-designed and pre-built modules.

CurbPak units are designed and built to ship as a singlepiece except sizes 860 and 1030. This minimizes in-stallation time and cost. Units can however be shippedin multiple pieces to accommodate various shipping andjob site requirements.

Fans

Double-Width, Double-Inlet (DWDI) fans and SingleWidth, Single-Inlet (SWSI) plenum fans are availablefor supply and return air fans. The plenum fan segmentscan accommodate multiple duct outlets, thus reducingthe amount of field duct work and transitions.

All of the CurbPak fan assemblies are internally iso-lated. Seismic isolation is available as an option.

FACTORY INSTALLED CONTROLS AND ELECTRICAL OPTIONS

YORK has the capability to furnish units with factory installed single-point power motor starter panels, disconnects, marine lights, sensors,actuators or complete unit automation. Factory installed wiring greatlyreduces installation time and cost.

Factory installed inverters, the YORK Air-Modulator, provide the mostefficient and cost effective VAV control in a complete factory package.Factory mounted inverters not only save field labor, but it also assuresproper fan balance for vibration free operation. While most fans arebalanced for a single speed, fans with inverters are factory balanced tooperate over the entire RPM range.

VARIABLE AIR VOLUME APPLICATIONS

Factory mounted variable frequency drives (YORK Air-Modulator) andvariable inlet vanes are available with the YORK CurbPak for VariableAir Volume Applications.

YORK Air-Modulator (AM):

YORK’s Variable Frequency Drive, the AM, offers the most efficientmeans of fan control for variable air volume systems. The Air-Modulatorvaries the speed of the fan to match the VAV load requirements.

The AM takes maximum advantage of the relation between fan speed andfan horsepower. With the AM, any reduction in fan speed results in acubic reduction in fan horsepower. For example, a 10% speed reductionresults in a 27% fan horsepower reduction!

The AM offers the following benefits over variable inlet vanes and dis-charge dampers: • Extended Equipment Life – soft start of motor and fan. • Quieter Fan Operation – fan operating at reduced speed and constant

line of efficiency. • Eliminates need for motor starter panels. • Improved system control and response – DDC controls with LED

digital display. • Proven reliability.

Variable Inlet Vanes

Variable inlet vanes are another method of energy efficient fan control.While the fan runs at a constant speed, the inlet vanes modulate the airentering the fan. This produces a reduced air volume resulting in loweroperating horsepowers.

END DEVICE FACTORY COMMISSIONING

Every end device that is Factory-mounted and wired willgo through a detailed automated commissioning processto ensure that every end device functions properly beforethe air-handling unit leaves the factory. As part of thiscommissioning process, a report will be generated andthis report will ship with the unit. The extensive commis-sioning the end devices go through at the factory wouldbe virtually impossible to duplicate in the field.

Through Cables on Shipping Splits – On all air-han-dling units with shipping splits, cables with field connec-tors will be supplied. The operator connects the auto-mated commissioning tester to the segment being testedand then connects test plugs to the through cables. Theautomated commissioning tester then performs a test toverify that there are no “open” or “shorts” in the throughcables and that all polarity is correct. On verification ofthis test, the automated commissioning tester recordsa pass condition.

Components Include:• 120VAC to 24VAC transformers (3)• Relays for fan start/stop & low-limit reset circuit• Circuit board for field & factory terminations• Low-limit reset button• Knockouts will be provided for customer wiring• Hinged front cover can be lifted off after opening 2"

AT – SOUND ATTENUATOR

Sound Attenuators are rated for two flow conditions,FORWARD and REVERSE. Forward flow occurs whenair and sound-waves travel in the same direction, as ina supply air duct or fan discharge. Reverse flow occurswhen sound-waves and air travel in opposing directions,as in a typical return-air system.

Because Attenuation values are generally higher in thefirst five octave bands in the reverse flow mode, com-pared to the forward flow mode, more economical si-lencer selections can often be made on the return-airsystems. These phenomena are illustrated below.

Under FORWARD FLOW conditions, high-frequencysound is refracted into the duct-silencer walls.

Under REVERSE FLOW conditions, sound is refracted awayfrom the walls and toward the center of the duct-silencer.

DESCRIPTION

Electric heaters are of “open coil” construction, with 80%nickel, 20% chromium coil elements machine crimpedto stainless steel terminals and amply supported on ce-ramic bushing isolators. All internal wiring of controls,contactors, etc., is complete including a 120V, 60 Hzcontrol circuit transformer. Field wiring input terminalblocks are provided for code sized (125%) copper (only)conductors. Largest terminals are for 500 MCM copperconductors, so heaters requiring over 304 amps/phasewill have two or more parallel terminals per phase.

Standard electric heaters include terminals for field con-nection of 120V control circuit transformer, and fusesper N.E.C. and U.L. (on heaters exceeding 48 amps).Field wiring diagram is mounted on inside of terminalbox cover. The terminals are clearly marked and knock-outs are provided per the latest N.E.C.

Heater Segments have disc automatic thermal cut-outsand a load carrying disc manual reset cut-out for eachcircuit. A differential pressure air flow switch with veloc-ity pick-up tube can be field set to sense minimum airflow.

MINIMUM AIR FLOWS

Electric heaters differ from steam or hot water coils inthat the heat output is constant as long as the heater isenergized. Therefore, sufficient air flow must be pro-vided to prevent overheating and nuisance tripping ofthe thermal cutouts. The minimum required velocity isdetermined from the graph on the basis of entering airtemperature and watts per square foot of cross seg-mental heating coil area.

EXAMPLE: Determine whether the minimum air veloc-ity requirement is met for a 108 kW heater installed witha CP400 Air Handling Unit. The unit is operating at 18,000cfm at a maximum inlet temperature of 65°F.

1. Heating Coil Area = 33 sq. ft.NOTE: Heating Coil Areas are found on page 38.

2. kW per sq ft. = 108 kW = 3.3 kW / sq. ft. 33 sq. ft.

3. Use top curve (below 80°F inlet air). Find 3.3 kW persquare foot on the vertical axis. Read the minimumface velocity required, which in this case is 205 feetper minute (fpm).

4. Air Handling Unit Face Velocity =

18,000 cfm = 545 fpm

33 sq. ft.

Since 545 FPM exceeds the minimum velocity require-ment of 205 FPM, this installation is satisfactory forheater operation.

IG – INDIRECT FIRED GAS HEATER

DESCRIPTION

Indirect Fired Gas Heater section consists of the stain-less steel primary and secondary heat exchanger withthe power burner design. The basic design allows thepower burner to inject the correct ratio of air and gas intothe primary heat exchanger where the main combustionoccurs. The heated products of combustion then passthrough the multiple secondary tubes heating each tubefor maximum heat transfer. The products of combustionthen pass to the inducer draft fan and through the flue.The air is heated by passing around the primary andsecondary tubes for optimal heat transfer. The heater isdesigned for 80% efficiency.

The furnace is U.L. approved but not the unit and comeswired with all necessary safety controls and valves in-stalled. The controls vary based on the BTU level and

Insurance Requirements selected. These units are de-signed to handle Natural Gas as a standard and can beselected to operate on LP Gas. The gas pressure avail-able at the unit of either type needs to be consideredwhen ordering the equipment.

APPLICATION / SELECTION

The nomenclature indicating the size of the heater refersto 10,000 BTUs. Example: the Size 25 that can be se-lected in a CP-44 refers to 250,000 BTU output.

Equations:

BTU Output Required =cfm x 1.08 x Temperature Rise Required

BTU Input = BTU Output ÷ .80

TURNDOWN OPTIONS AND GUIDELINES

The CurbPak furnaces are available with the followingburner firing arrangements.

ON/OFF FIRING: The burner in the on position firesat full rating

TWO-STAGE: The burner fires at 50% capacityon Low fire and 100% capacity onHigh fire

3-1 MODULATION: The burner will modulate for 100%- 33% of full fire

10-1 MODULATION: The burner will modulate from100% - 10% of full fire

When choosing the proper turn down three issues shouldbe considered.1. Greater modulation provides improved temperature

control. If the furnace is modulated to its minimumfire position, and controls determine there is too muchfurnace capacity, then the furnace is staged on andoff, on carefully chosen time delays, to satisfy thelight load heating requirements. The 3-1 option is gen-erally sufficient particularly if design temperature risedoes not exceed 30-40 degrees.

2. The greater the range of modulation the greater thecost.

3. Experience requires that a furnace should not turndown to a temperature rise less than 5-8 degrees.

Greater modulation decreases the flue stack tempera-ture at low fire, increases the amount of condensa-tion, and can decrease the life of the heat exchangereven though all CP furnaces utilizes a 430 stainlesssteel primary and 409 stainless steel secondary heatexchanger tubes along with condensate drains. Thesegrades of stainless steel have been selected for theideal combination of thermal and corrosion protection.The condensate line must be adequately sized,trapped, along with drainage of the condensate perlocal code.

TEMPERATURE RISE VERSUS FIRING RATECONSIDERATIONS

1. Furnace design temperature rise is less than 25 de-grees: Only Single or Two-Stage furnaces are recom-mended.

2. Furnace design temperature rise is 15-49 degrees:The 3:1 option is the only modulation option availableand modulates down to 5-16 degrees temperature rise.

3. Furnace temperature rise is 50-70 degrees: The 3:1burner is strongly recommended instead of the 10-1furnace.

4. Furnace temperature rise is 70-100 degrees: Both 3:1and 10:1 Modulation can be considered.


INSURANCE OPTIONS & LOCAL CODE REQUIREMENTS

There are two types of pipe trains available on powerduct furnaces. The insurance options for these pipe trainsare as follows:

a. IRI – Industrial Risk Insurersb. FM – Factory Mutual

GAS PRESSURE REQUIREMENTS

The CurbPak furnaces are designed to handle a widerange of inlet gas pressures as listed below. Exact val-ues depend on the required options and capacity of thefurnace. These limits must be adhered to in order to ob-tain safe and reliable performance. Please allow this tosupersede all previous data.

If the gas pressure exceeds the furnace maximum thenthe field must provide a pressure regulator to reduce theinlet pressure to acceptable levels.

Engineering Data

All IRI gas trains are provided with atmospheric vents onthe vent valve piped to the exterior of the unit. Local codesand project requirements vary. For this reason, salesmust carefully review the requirements that apply to thearea where the equipment is to be installed.

If the inlet pressures fall short of the furnace minimumthe field must provide a booster pump to increase inletpressure to acceptable levels.

The YORK pressure range is competitive, however, notethat the extra turn down, associated with a 10-1 burnerrequires a greater inlet pressure.

Unit SelectionSELECTING A CURBPAK AIR HANDLING UNITCurbPak air handling units permit selection of compo-nents to meet individual job requirements. The wide se-lection of basic segments, optional components, coils,and accessories, enables the design engineer to obtainoptimum performance and temperature control.

Selection of the optimum system for each individual ap-plication requires only the following simple steps:Step 1 - Select Unit Size Based on Coil Face Velocity.Step 2 - Choose the Segments Required for the System.Step 3 - Select Coils from the YORK Computer Selection Program.Step 4 - Calculate the Total Static Pressure (TSP) of the Unit.Step 5 - Select Fan & Determine Fan Brake Horsepower (BHP) &RPM.

STEP 1SELECT UNIT SIZE

Minimum Coil Area = cfm Maximum Coil Face Velocity

Select the unit size that has the minimum coil area avail-able. Cooling coils are typically selected at 500 fpm, whileheating coils are typically selected at 700-800 fpm.

The Quick Selection Tables on page 13 should be usedto determine unit size.

STEP 2CHOOSE THE SEGMENTS

Select the various segments required to satisfy the sys-tem. This includes fan, coil, filter, inlet and any other seg-ment required for the particular application.

STEP 3SELECT COILS

Select the heating and/or cooling coils by using theYorkWorks Coil Selection Program.

STEP 4CALCULATE THE TOTAL STATIC PRESSURE

Utilizing the schematic diagrams on pages 42-43, de-fine the items that must be included to calculate thestatic pressure for the supply and/or return air fan. TheInternal Static Pressure (ISP) is the sum of the air pres-sure drops for the internal components.Determine the face velocity of all the components.

Face Velocity = cfm Area

The Air Pressure Drop tables on pages 41-55 should beused to determine the static pressure of each componentbased on component face velocity.NOTE: The listed filter pressure drops are for clean fil-

ters. The approximate pressure drop of dirty fil-

ters is twice the air pressure drop of clean fil-ters. The best estimate is an average of the two(2) values.

The TSP equals the sum of all the internal static pres-sures and the external static pressure (TSP = ISP + ESP).

STEP 5SELECT FAN

The Fan and Motor Data tables on pages 18-20 showsthe available fan sizes in each unit size. Based on the fansize, cfm and TSP, enter the appropriate fan curve andread BHP and RPM.Account for belt and drive losses by adding 3-6% to thefan BHP. Select the appropriate motor size to accommo-date the fan BHP.

Air Pressure Drop

SYSTEM EFFECT FACTOR (SEF)

The performance of fans is determined with a straightduct on the fan outlet. This duct configuration was usedin testing to develop the fan performance curves. There-fore, when the fan is applied without sufficient outletduct, the SEF must be accounted for to use the FanTables, Form 100.10-EG1.1. This does not apply toducted outlet fans with a minimum length of straightduct that measures three times the fan diameter. Thefan velocity APD table on page 49 contains values forsystem effect at various velocities.

The air pressure drop tables are presented to accountfor the difference between the return and the supply air.This is almost always the case since air is exhaustedfrom kitchens, rest rooms, etc.

Use examples and schematic diagrams on pages 42and 43 as a guide to calculating the Total Static Pres-sure for use with the fan curves. Modify the examples tosuit the actual application.

VELOCITY PRESSURE DROP

AMCA Standard 201 is the basis of all static calcula-tions and fan applications in the CurbPak. This stan-dard details the velocity pressure drop that occurs withunducted DWDI fans (return air fans). AMCA fan rat-ings are done with an outlet duct of 3 fan diameters inlength.

The velocity pressure drop is based on fan outlet veloc-ity and must be taken into consideration with return fanapplications and supply fans that are not followed bythe minimum AMCA recommended length of straightduct.

PIPE CHASE ENCLOSURE

LD06280

Drain connection opposite pipe chase is standard.A header panel covers entire segment.

NOTE: All pipe chases are factory assembled. Typically pipe chases for unit sizes65 to 215, will be factory-mounted. Pipe chases on unit sizes 250 and abovewill ship loose for field mounting.

COIL CONNECTION LOCATIONS (For reference only)

LD00060(r)

NOTES: 1. All coil connection locations begin at a reference point 6.5" above the bottom of the base of the unit for cooling coils in SC, MCand LC segments, and 3.0" downstream the entering air side of the coil segment. For heating coil segments, the reference point is5.75" above the bottom of the base.

2. Sizes 65 - 305 with multiple coils in the same segment, coils are adjacent to one another with no space in between.3. Sizes 350 - 1030 allow 3.0" space after cooling coils and no space after heating coils.4. Condensate connection is 1-1/4" MPT, schedule 40 pipe. Connection is located 2.625" above the bottom of the base of the unit and

at the midpoint of the coil segment.5. Pipe chase is not in air stream. Access to unit cannot be achieved through pipe chase because of header cover panel.6. Wall thickness of pipe chase, header covers, return bend panel are 1 inch with insulation.

* Usable working clearance depth is approximately 18".
