Copyright 2004 Carrier Corporation Form 38QRC-1PD

The 38QR Energy-Efficient condens-ing unit incorporates innovative tech-nology to provide reliable cooling andheating performance. Built into theseunits are features most desired by theindustry, including:• SEER(Seasonal EnergyEfficiency

Ratio) ratings of up to 11.0 whenmatched with Duct Free SystemFan Coils. All models are UL(Underwriters’ Laboratories); UL,Canada; ARI and CEC (CaliforniaEnergy Commission) listed.

• A wide range of accessories isavailable to meet a variety ofinstallation requirements.

• The 38QR can be installed within6 in. of an outside wall, on a roof,balcony, or on or under a deck.

Features/BenefitsSimple servicing andmaintenanceRemoving a single panel on outdoor units provides immediate access to the isolated compressor and control com-partment, allowing a service technician access to check unit operation without a loss of condenser airflow. In addition, 38QR units have a blow-thru design for the outdoor section which means that dirt accumulates on the inside sur-face of the coil. Coils can be cleaned quickly from the outside using a pres-sure hose and detergent without re-moving grilles or using fin combs.

Secure operationIf security is an issue, outdoor and indoor units are connected only by refrigerant piping and wiring to pre-vent intruders from crawling through ductwork.

Liquid line solenoid valve is an electrically operatedshutoff valve that is installed at the outdoor unit to stop andstart refrigerant flow in response to compressor operation.The valve maintains a column of refrigerant in the liquidline between compressor operating cycles and is requiredfor certain long line applications and to improve systemperformance.Low ambient kit is a solid-state head pressure controllerdesigned to control condenser fan cycling, and is activatedby a pressure sensor. It is specifically designed to controlfan motor cycles in response to saturated condensing pres-sure. This device maintains a constant saturated condens-ing temperature of 100 F ±10° F at outdoor airtemperatures between 55 and –20 F and can be used onall condensing units without changing the fan motor.Winter start control is an SPST (single-pole, single-throw) delay relay. The control bypasses the low-pressureswitch for approximately 3 minutes to permit start-upfor cooling operation under low load conditions at low-

ambient temperatures. Winter start control can also beused to provide low-ambient cooling at outdoor ambienttemperatures between 55 F and 40 F.Crankcase heaters are available for units with scrollcompressors. The heater clamps onto compressor oilsump. Recommended for low-ambient applications.A wind baffle is a sheet metal wrapper used to provideimproved unit operation during high winds.Wall mount brackets are mounted to the outside of thestructure to raise unit from ground level, or to mount theunit on a wall adjacent to a sloping roof. Wall mounts arealso useful in areas of heavy snowfall or where space is at apremium. Wall mounts can be used with any 38QR unit.Snow or ice stands — The snow or ice stand must beconstructed in the field using field-supplied materials.

I Determine the type of fan coil which bestsuits the application (refer to Systems Indextable on page 8).The 38QR can be matched with several types of fancoils with overlapping capacities to choose from.Select the system type which best meets the jobconditions. This example uses a nominal 2-ton fancoil.

II Determine cooling load requirements atdesign conditions.Required Load Conditions:Required Cooling Capacity (TCG) . . . .24,000 BtuhSensible Heat Capacity (SHC) . . . . . .16,800 BtuhTemperature Air Entering Condensing Unit . . . . . . . . . . . . . . . . . . . .95 FTemperature Air Entering Indoor Unit (EAT.) . . . . . . . . . 82 F db/68 F wbRequired Heating Capacity . . . . . . . . .8,500 BtuhIndoor Heating Design Conditions . . . . . . . . .68 FOutdoor Heating Design Conditions . . . . . . . . 0º Fdb — dry bulbwb — wet bulb

III Select system that satisfies load requirements.Enter the Systems Index table on page 8 at systemsfor 24,000 Btuh, and select the system that bestapproximates cooling and heating requirements.System 32C with a nominal net capacity of24,000 Btuh cooling and 22,600 Btuh heating isthe system selected. The system consists of a38QR-024C outdoor unit matched with one40QAE024 unit.

IV Determine if system selected satisfies coolingrequirements.Enter Cooling Capacities table on page 10 at highspeed and 95 F outdoor entering air temperature(EAT, air entering condenser). By interpolation, at68 F EAT, the system gross capacity is 24,900 Btuhcooling [(26,500 – 24,500) x (1/5) + 24,500], and15,740 Btuh SHG (gross sensible capacity). Adjustthe SHG in accordance with Note 2 of the Combi-nation Ratings table, using the correction factor foran 82 F edb (entering air dry bulb), and a 0.03 BF(bypass factor). The result is an adjusted SHG of16,877 Btuh. The total gross cooling capacityof 24,900 Btuh and the sensible capacity of16,877 Btuh satisfy stipulated cooling loadrequirements.

V Determine if system selected satisfies heatingrequirements.Enter Instantaneous and Integrated Heating Ratingstable for System 32H on page 20 at 0º F outdoordb. By interpolation, the system capacity is between65 and 70 F for integrated heating [–(7320 – 7710)x (2/5) + 7320 = 7476]. This is the value whichreflects the net room effects after defrost energy.This value is short of the required heating capacity,however, the 40QAE units have a standard electricheater which will work in conjunction with heatpump heating (booster heat mode).

VI Determine net cooling capacity and systemenergy efficiency ratio.Determine net cooling capacity (refer to CoolingCapacity table for system 32C on page 10). Nettotal cooling capacity must be interpolated asfollows: (26,000 – 24,000) x (1/5) + 26,000 = 26,400 BtuhTo determine the energy efficiency ratio (EER), sys-tem kW must be interpolated from the CoolingCapacity table for system 32C in the same manner:(2.47 – 2.40) x (1/5) + 2.40 = 2.41 kWThen calculate EER: Net Cooling Capacity EER kW x 1000

NOTE: The SEER (Seasonal Energy EfficiencyRatio) CANNOT be calculated for this system.SEERs can only be found as a direct result of testingat specified ARI conditions. See the ARI CapacityRatings on page 3.

VII Determine COP (coefficient of performance)at the design point.To calculate the COP at the design point, interpo-late capacity as in Step V to arrive at a capacity of7476. Interpolate the kW between 1.63 and 1.62to be 1.625. COP = 7476/1.625 x 3.412 ÷ 1000 = 1.48NOTE: The HSPF (heating seasonal performancefactor) CANNOT be calculated for this system.HSPFs can only be found as a direct result of testingat specified ARI conditions.

Unit selectionSelect equipment to match or be slightly less than antici-pated peak cooling load. This provides better humiditycontrol, fewer unit cycles, and less part-load operation.

Heating and cooling design loads must both be checked.To meet heating requirements, calculate heater in additionto heat pump capacity. Since indoor unit is off duringdefrost cycles, it is not necessary for electric heater to meettotal heating requirement. For units used in spaces with high sensible loads, baseequipment selection on unit sensible load, not on totalanticipated load. Adjust for anticipated room wet bulb tem-perature to avoid undersizing equipment. Heating load using outdoor air must be checked in addi-tion to cooling load. Heating load of outdoor air cangreatly reduce heating capability.

When selecting equipment that has outdoor air intro-duced into the unit, determine the mix conditions of roomair and outdoor air at design conditions. The coolingcapacity tables in this literature are based on 80 F edb. Toselect the proper equipment, adjust for actual dry-bulb andwet-bulb conditions with the required outdoor air.Unit combinations and coil mixed matchesThe 38QR unit is the only unit approved for use with theCarrier 40QAE and 40QKE systems, and can also be usedwith other fan coil units.Unit mounting (outdoor)Unit leveling — For reliable operation, units should belevel in all planes.Clearance — Provide adequate clearance for airflow. Seedimensional drawings for proper clearances. The heatpump units are designed for free-blow application. Airinlets and outlets should not be restricted. Outdoor fanexternal static pressure available is less than 0.1 in. wg.Unit location — Heat pump units should not be stacked.Defrosted condensate from upper unit will refreeze onlower unit. Units may be wall mounted, pad mounted atground level, roof mounted, or mounted on or under adeck. Be sure that water from roof does not drain directlyonto the unit. Units must be mounted so that snow will not obstruct air-flow and so that defrosting coil ice can drain freely fromthe outdoor unit drain pan. Snow and ice stands can befield fabricated to raise 38QR units to meet these condi-tions if necessary. Contact your Carrier representative fordrawings.NOTE: Accessory kits are available for wall mounting38QR unit.

If 38QR outdoor heat pump units are mounted near awall, the condenser air should discharge toward the wall.This will provide inherent coil protection and the best pos-sible sound and airflow performance.Metering devicesThe 38QR units use a piston type metering device locatedin the outdoor liquid service valve (for heating). Pistonsfunction as check valves in addition to being meteringdevices.NOTE: The 38QR split systems use Type “B” Chatleffstyle AccuRater® pistons. DO NOT mix Type “A” andType “B” pistons. See the Residential Long-Lines Applica-tions Guide for changes in piston sizes due to long lines.

Refrigerant linesGeneral refrigerant line sizing:

1. All charges, line sizing, and capacities are based onruns of 25 ft. For runs over 25 ft, consult the Resi-dential Long Line Application Guide for proper linesizing, charge and AccuRater refrigerant meteringdevice sizing.

NOTE: For runs less than 25 ft, some of the charge mayneed to be removed to obtain the correct system super-heat. The minimum line length should be 8 ft.

MAXIMUM LINE LENGTHS

2. Refrigerant lines should not be buried in the ground. Ifit is necessary to bury the lines, not more than 36 in.should be buried. Provide a minimum 6-in. verticalrise to the service valves to prevent refrigerantmigration.

3. Both refrigerant lines must be insulated. Use a mini-mum of 1/2-in. thick insulation. Closed-cell insulationis recommended in all long-line applications.

4. Special consideration should be given to isolatinginterconnecting tubing from the building structure.Isolate the tubing so that vibration or noise is nottransmitted into the structure.

5. The 38QR units are shipped with a holding charge ofR-22 refrigerant. Charge is based on fan coil withsmallest charge and 25 ft of line. See ARI CapacityRatings tables for system charges. Add additionalcharge by weight as necessary and check the chargewith a superheat calculator.

Wiring — Use only copper wires from the disconnect tothe unit terminal block. Aluminum and copper-clad alumi-num wires are not acceptable.

All 38QR heat pump systems provide 24-v power forthe outdoor unit from the indoor unit.

Fan coils should have a separate disconnect for indoorand outdoor units. In addition, cassette fan coils requireseparate disconnects for both the fan and the heater.
