Product Data

C10108

Fig. 1 -- 38AUQ -- 07--12 shown

Gemini split system heat pump systems save energy and provide outstanding heating and cooling all year with:

S All-season comfort in any climate

S High energy savings capability

S Suitability for new construction or replacement

FEATURES/BENEFITS

System indoor and outdoor sections offer outstanding performance in either the cooling or heating mode

Heat pump system energy savings opportunity

Electrical energy consumption is always a prime concern when selecting an air-conditioning system for a commercial application. An easy, effective way to save energy is to install a heat pump. When building plans call for a heat pump, consider a matched Carrier 38AUQ/40RUQ heat pump system. These systems not only offer highly efficient cooling, they also provide a clean, safe, efficient source of heat. In fact, they are capable of delivering more than 3 units of heat energy for each unit of electrical power consumed.

Heat pump uniqueness

The outstanding performance of these heat pump systems is due to the heat pump’s ability to absorb and transfer heat — from outdoors to indoors for heating, and from indoors to outdoors for cooling. System indoor and outdoor sections operate as evaporators or condensers, depending on whether heating or cooling is required. The heating cycle starts with the outdoor coil absorbing heat from the surrounding air (even outside air at extremely cold temperatures), and ends with the indoor coil releasing or rejecting heat to the air around it.

38AUQ application versatility

Whether for a new application or replacement, these Carrier split system heat pumps offer time-proven performance for year-round comfort in any climate. With matching 40RUQ air handler, the units standard cooling operation ranges up to 125_F (52_C) and down to 35_F (2_C) ambient temperatures. If lower ambient cooling temperatures are required, Carrier’s Motor Master controller will allow operation down to --20_F (--29_C) ambient temperatures.

FEATURES/BENEFITS (cont.)

Rugged long life compressor

The 38AUQ outdoor units are equipped with a scroll compressor for superior efficiency and long life. Crank case heaters are available where required and each circuit is further protected by a suction line accumulator to protect during the defrost cycles or unique applications plus provide important oil management, all resulting in higher reliability.

Controls for performance efficiency

These units offer the building owner operating controls and components designed for performance dependability.

The highly efficient hermetic scroll compressors are engineered for long life and durability. The compressor includes overload protection and compressor vibration isolation for further enhancement of quiet operation. The high-pressure switch protects the entire refrigeration system from abnormally high operating pressures. A loss-of-charge switch is also provided to protect the system against low charge conditions.

Each unit utilizes the the Comfort Alertt diagnostic and troubleshooting control system. This protects the units operation and provides valuable diagnostic information such as:

-- System Go LED indicator -- Fault LED indicator -- Compressor fault LED indicator -- Phase loss protection -- Phase reversal protection -- Anti short cycle protection

The 24-v--75VA control circuit transformer permits quick, easy wiring of standard and programmable 24-v thermostats.

The 24--v--75VA control circuit transformer also comes with a re--settable circuit breaker for extra protection.

Latest safety standards are assured through UL (Underwriters’ Laboratories), UL -- Canada and ETL (Electrical Testing Laboratories) approval .

The 38AUQ units utilize a reliable defrost board with field configurable timed defrost cycles. The defrost board may be easily configured for defrost cycles of 30 to 90 minutes, depending upon the application.

Motor failure due to electrical overload is prevented by temperature and current sensors. Coil quality and performance are enhanced by copper tubes and aluminum fins, which provide maximum heat transfer. The coil is circuited for subcooling. A large heat transfer surface offers additional efficiency.

Innovative Carrier 40RUQ indoor units are custom matched to 38AUQ outdoor units for superior system performance

The 40RUQ Heat Pump air handler has excellent fan performance, efficient direct-expansion (DX) coils, easy installation, and a unique combination of indoor air quality features. Its versatility and state-of-the-art features help to ensure that the heat pump system provides economical performance now and in the future.

Easy installation and service — The 40RUQ multi--position design and component layout helps to get the unit installed and running quickly. The direct-expansion (DX) coils have factory-installed thermostatic expansion valves (TXVs) with matching distributor nozzles. All 40RUQ units also include factory-installed check valves and piping for heat pump duty with matching 38AUQ units.

The 40RUQ units can be converted from horizontal to vertical operation simply by repositioning the unit. Drain pan connections are duplicated on both sides of the unit.

Fan motors and contactors are pre--wired. For easier service, the filters, motor, drive, TXVs, check valves, and coil connections are accessible by removing a single side panel.

Indoor-air quality (IAQ) features — The unique combination of IAQ features in the 40RUQ Series indoor units helps to make sure that only clean, fresh, conditioned air is delivered to the occupied space.

In the Cooling mode, direct-expansion (DX) cooling coils prevent the build-up of humidity in the room, even during part-load conditions.

Standard 2-in. disposable filters remove dust and airborne particles from the occupied space.

Thermal insulation contains an immobilized anti-microbial agent to inhibit the growth of bacteria and fungi. The anti-microbial agent is registered with the U.S.

Environmental Protection Agency (EPA).

The pitched corrosion-free drain pan can be adjusted for a right- or left-hand connection to provide positive drainage and to prevent standing condensate. Each unit contains two separate drain pans which are provided for either vertical or horizontal fan coil positions.

The 40RUQ accessory economizer can provide ventilation air to improve indoor air quality. When used in conjunction with Carrier Comfort System thermostats and CO2 sensors or PremierLink controller, the economizer admits fresh outdoor air to replace stale, recirculated indoor air.

Economy — The 40RUQ Series air handlers have low initial costs, and they continue to save money by providing reduced installation expense and energy-efficient performance.

Quick installation reduces installation costs, and TXVs, check valves, and heat pump piping are factory-installed.

High-efficiency, precision-balanced fans minimize air turbulence, surging, and unbalanced operation, cutting operating expenses.

The economizer accessory precisely controls the blend of outdoor air and room air to achieve comfort levels.

When the outside air enthalpy is suitable, outside air dampers can fully open to provide “free” cooling.

A U Q

Rugged dependability — The 40RUQ units are made to last. The die-formed galvanized steel panels ensure structural integrity under all operating conditions. Galvanized steel fan housings are securely mounted to a die-formed galvanized steel deck. Coil housings are galvanized steel, and coils have aluminum fins mechanically bonded to copper tubes. The condensate drain pans provide corrosion-free performance.

Coil flexibility — Model 40RUQ coils have galvanized steel casings; inlet and outlet connections are on the same end. The coils are designed for use with Puron (R--410A) refrigerant and have 3/8-in. diameter copper tubes mechanically bonded to aluminum sine-wave fins. The coils include matched, factory-installed TXVs with matching distributor nozzles. Check valves and heat pump piping are also included in all 40RUQ units.

Duplicate piping access holes on both sides of the unit eliminate drilling; condensate connections for both vertical and horizontal installations are also provided on both sides of the unit.

Factory--installed options

Alternate fan motors and drives are available to provide the widest possible range of performance.

Prepainted steel units are available from the factory for applications that require painted units. Units are painted with American Sterling Gray color.

Field--installed accessories

CO2 sensors can be used in conjunction with the economizer accessory to help meet indoor air quality requirements. The sensor signals the economizer to open when the CO2 level in the space exceeds the set point. A Carrier Comfort System programmable thermostat can be used to override the sensor if the outside--air temperature is too high or too low.

Condensate drain trap includes an overflow shutoff switch that can be wired to turn off the unit if the trap becomes plugged. Kit also includes a wire harness that can be connected to an alarm if desired. The transparent trap is designed for easy service and maintenance.

Discharge plenum directs the air discharge directly into the occupied space; integral horizontal and vertical louvers enable redirection of airflow. Accessory is available unpainted or painted. Field assembly is required (only applicable for vertical application).

Economizer (enthalpy controlled) provides ventilation air and “free” cooling if outside ambient temperature and humidity are suitable. It can also be used with CO2 sensors to help meet indoor air quality requirements.

Electric resistance heat coils have an open--wire design and are mounted in a rigid frame. Safety cutouts for high temperature conditions are standard. Terminal block for single--point power connection is included.

Two--row hot water coils have copper tubes mechanically bonded to aluminum plate fins and non--ferrous headers.

Overhead suspension package includes necessary brackets to support units in horizontal ceiling installations.

Carrier’s line of thermostats provide both programmable and non--programmable capability with the new Debonairr line of commercial programmable thermostats. The TEMP System controls offer communication capability with staged heating and cooling, and the Commercial Electronic thermostats provide 7--day programmable capability for economical applications.

Return--air grille provides a protective barrier over the return--air opening and gives a finished appearance to units installed in the occupied space. Accessory is available unpainted or painted.

One--row steam coil has copper tubes and aluminum fins.

The Inner Distributing Tube (IDT) design provides uniform temperatures across the coil face. The steam coil has a broad operating pressure range; up to 20 psi (138 kPag) at 260_F (126_C). The IDT steam coils are especially suited to applications where sub--freezing air enters the unit.

Subbase provides a stable, raised platform and room for condensate drain trap connection for vertical floor--mounted units. Accessory is available unpainted or painted.

Factory--installed options Alternate fan motors and drives are available to provide the widest possible range of performance.

Prepainted steel units are available from the factory for applications that require painted units. Units are painted with American Sterling Gray color.

Staged Air Volume (SAV) system saves energy and installation time by utilizing a Variable Frequency Drive (VFD) to automatically adjust the indoor fan motor speed in sequence with the units cooling operation. Per ASHRAE

90.1 2010 standard section 6.4.3.10.b, during the first stage of cooling operation the VFD will adjust the fan motor to provide 2/3rd of the total cfm established for the unit. When a call for the second stage of cooling is required, the VFD will allow the total cfm for the unit established (100%).

During the heating mode the VFD will allow total design cfm (100%) operation and during the ventilation mode the VFD will allow operation to 2/3rd of total cfm.

Compared to single speed indoor fan motor systems, Carrier’s SAV system can save substantial energy, 25%+*, versus single speed indoor fan motor systems.

*Data based on .10 ($/kWh) in an office application utilizing Carrier’s HAP 4.6 simulation software program.

The VFD used in Carrier’s SAV system has soft start capabilities to slowly ramp up the speeds, thus eliminating any high inrush air volume during initial start--up. It also has internal over current protection for the fan motor and a field installed display kit that allows adjustment and in depth diagnostics of the VFD.

This SAV system is available on models with 2--stage cooling operation with electrical mechanical controls.

The SAV system is very flexible for initial fan performance set up and adjustment. The standard factory shipped VFD is pre--programmed to automatically stage the fan speed between the first and second stage of cooling. The unit fan performance static pressure and cfm can be easily adjusted using the traditional means of pulley adjustments. The other means to adjust the unit static and cfm performance is to utilize the field installed

Display Kit and adjust the frequency and voltage in the VFD to required performance requirements. In either case, once set up, the VFD will automatically adjust the speed between the cooling stage operations.

Field--installed accessories CO2 sensors can be used in conjunction with the economizer accessory to help meet indoor air quality requirements. The sensor signals the economizer to open when the CO2 level in the space exceeds the set point. A Carrier Comfort System programmable thermostat can be used to override the sensor if the outside--air temperature is too high or too low.

Economizers -- temperature dry bulb controlled --

LONG LINE APPLICATIONS

An application is considered Long Line when the refrigerant level in the system requires the use of accessories to maintain acceptable refrigerant management for systems reliability. Defining a system as long line depends on the liquid line diameter, actual length of the tubing, and vertical separation between the indoor and outdoor units.

For Heat Pump systems, the chart below shows when an application is considered Long Line. Beyond these lengths, long line accessories are required:

Accessory Description and Usage (Listed Alphabetically)

1. Compressor Start Assist -- Capacitor and Relay Start capacitor and relay gives a “hard” boost to compressor motor at each start up.

Usage Guideline:

Not required on this unit since compressor always starts unloaded.

Available if required by local codes.

2. Crankcase Heater An electric resistance heater which mounts to the base of the compressor to keep the lubricant warm during off cycles. Improves compressor lubrication on restart and minimizes the chance of liquid slugging.

Usage Guideline:

Required in low ambient cooling applications.

Required in long line applications.

3. Evaporator Freeze Thermostat An SPST temperature--actuated switch that stops unit operation when evaporator reaches freeze--up conditions.

Usage Guideline:

Required when low ambient kit has been added.

4. Isolation Relay An SPDT relay which switches the low ambient controller out of the outdoor fan motor circuit when the heat pump switches to heating mode.

Usage Guideline:

Required in all heat pumps where low ambient kit has been added.

5. Low--Ambient Pressure Switch A long life pressure switch which is mounted to outdoor unit service valve. It is designed to cycle the outdoor fan motor in order to maintain head pressure within normal operating limits. The control will maintain working head pressure at low--ambient temperatures down to 0_F (--17.8_C) when properly installed.

Usage Guideline:

A Low--Ambient Pressure Switch must be used when cooling operation is used at outdoor temperatures below 55_F (12.8_C).

Suggested in all commercial applications.

6. Liquid--Line Solenoid Valve (LLS) An electrically operated shutoff valve which stops and starts refrigerant liquid flow in response to compressor operation. It is to be installed at the outdoor unit to control refrigerant off cycle migration in the heating mode.

Usage Guideline:

An LLS is required in all long line heat pump applications to control refrigerant off cycle migration in the heating mode. See Long Line Guideline.

Suggested for all commercial applications.
