Product Data

Durable, dependable components Compressors are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent protection.

Direct-- drive multi--speed brushless DC blower motor is standard on all 50VT models. Direct --drive, PSC condenser--fan motors are designed to help reduce energy consumption and provide for cooling operation down to 40_F(4.4_C) outdoor temperature. MotormasterR II low ambient kit is available as a field installed accessory.

Thermostat Controls designed to work as a system with Carrier’s small packaged product.

Thermostatic Expansion Valve -- A hard shutoff, balance port TXV maintains a constant superheat at the evaporator exit (cooling cycle) resulting in higher overall system efficiency.

Refrigerant system is designed to provide dependability. Liquid filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier.

Puron Environmentally Sound Refrigerant is Carrier’s unique refrigerant designed to help protect the environment. Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. Puron refrigerant is in service in millions of systems, proving highly reliable, environmentally sound performance.

Easy Installation

Factory--assembled package is a compact, fully self--contained, heat pump unit that is prewired, pre--piped, and pre--charged for minimum installation expense. These units are available in a variety of standard capacity ranges with voltage options to meet residential and light commercial requirements. Units are lightweight and install easily on a rooftop or at ground level. The high tech composite base eliminates rust problems associated with ground level applications.

High and Low Pressure Switches provide added reliability for the compressor.

Indoor and Outdoor coils are computer--designed for optimum heat transfer and efficiency. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit. Copper fin coils and pre--coated fin coils are available from the factory by special order. These coils are recommended in applications where aluminum fins are likely to be damaged due to corrosion. They are ideal for seacoast applications.

Low sound ratings ensure a quiet indoor and outdoor environment with sound ratings as low as 72dBA.

Easy to service cabinets provide easy single--panel accessibility to serviceable components during maintenance and installation. The base with integrated drain pan provides easy ground level installation with or without a mounting pad. Convenient hand--holds are provided to manipulate the unit on the jobsite. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4--in. wide perimeter flange makes frame mounting on a rooftop easy.

Convertible duct configuration

Unit is designed for easy use in either downflow or horizontal applications. Each unit is easily converted from horizontal to downflow with the two duct covers, standard on 3 phase units and available as an accessory for single phase units. Downflow operation is easily provided in the field to allow vertical ductwork connections. The basepan utilizes knockout style seals on the bottom openings to ensure a positive seal in the horizontal airflow mode.

Cabinets are constructed of heavyduty, phosphated, zinc--coated prepainted steel capable of withstanding 500 hours in salt spray. Interior surfaces of the evaporator and electric heater compartments are insulated with cleanable semi--rigid insulation board, which

SELECTION PROCEDURE (WITH EXAMPLE)

1. Determine cooling and heating requirements at design conditions:

Given:

Required Cooling Capacity (TC) 34,500 Btuh..........

Sensible Heat Capacity (SHC) 26,000 Btuh............

Required Heatin g Capacity 60,000 Btuh...............

Condenser Entering Air Temperature 95°F(35°C).......

Indoor--Air Temperature 80°F(27°C) edb 67°F(19°C) ewb

Evaporator Air Quantity 1200 CFM..................

External Static Pressure 0.200 IN.W.C.................

Electrical Characteristics 208--1--60...................

2. Select unit based on required cooling capacity.

Enter Net Cooling Capacities table at condenser entering

temperature of 95°F(35°C). Unit 036 at 1200 cfm and 67°F (19°C) ewb (entering wet bulb) will provide a total capacity of 36,000 Btuh and a SHC of 27,400 Btuh. Calculate SHC correction, if required, using Note 4 under Cooling Capacities tables.

3. Select heating capacity of unit to provide design condition requirement.

In the Heating Capacities and Efficiencies table, note that the 036 size unit will deliver 34,800 BTUH at the ARI high temp rating point. To achieve 60,000 BTUH, accessory electric heat will be required. Use the Balance Point Worksheet to plot the load line with the unit capacity. The difference between the load line and unit capacity at the design heating temperature is the amount of electric heat that will be required.

Maximum cooling airflow — To minimize the possibility of condensate blow--off from the evaporator, airflow through the units should not exceed 450 cfm per ton.

Minimum cooling airflow — Minimum cooling airflow is 350 cfm per ton in cooling mode. Airlow can be lower in certain modes when humidity removal is an issue however, low airflow could result in indoor coil freezing and/or refrigerant floodback.

Minimum ambient cooling operation temperature —All standard units have a minimum ambient cooling operating temperature of 40_F(4.4_C). With accessory low ambient temperature kit, units can operate at temperatures down to 0_F (17.8_C).

Maximum operating outdoor air temperature for cooling is 125_F (51.7_C).

CONTROLS

Operating sequence

When power is supplied to unit, the transformer (TRAN) is energized.

On units with crankcase heater, heater is also energized.

Cooling — With the thermostat in the cooling position, the thermostat makes circuit R--O. This energizes the reversing valve solenoid (RVS) and places the unit in standby condition for cooling.

As the space temperature rises, the thermostat closes circuit R--Y. A circuit is made to contactor (C), starting the compressor (COMP) and outdoor--fan motor (OFM). Circuit R--G is made at the same time and starts the indoor--fan motor (IFM).

When the thermostat is satisfied, contacts open, deenergizing C. The COMP and OFM stop, and the IFM stops after the preselected time delay.

Heating — On a call for heat, thermostat makes circuites R--Y and R--G.

A circuit is made to C, starting COMP and OFM. Circuit R--G also is complted, energizing IFR and starting IFM after the selected time

50VT

delay. Should room temperature continue to fall, circuit R-- W is made

through second-- stage thermostat. If optional electric heat package is used, a relay is energized, bringing on first bank of supplemental electric heat. When thermostat is satisfied, contacts open, deenergizing contactor and relay; motors and heaters deenergize.

Defro st — Defrost board (DB) is a time and temperature control, which includes a field--selectable time period (dip switch 1 and 2 on the board) between checks for defrost (30, 60, 90, or 120 minutes). Electronic timer and defrost cycle start only when contactor is energized and defrost thermostat (DFT) is closed.

The defrost board is also equipped with a third dip switch for selecting Quiet Shift operation. The Quiet Shift operation turns compressor off at defrost initiation and termination. Unit is factory shipped with quiet shift turned off.

Defrost mode is identical to cooling mode, except outdoor fan motor stops and a bank of optional electric heat turns on to warm air supplying the conditioned space.

NOTE:

1. Compressor time delay occurs through the defrost control board.

2. Defrost control board has built in 5 minute compressor delay; once the compressor has started and then stopped, it cannot be restarted again until 5 minutes have elapsed.
