INTRODUCTION

The ACCL series air cooled condensing units from GE Air Conditioners are designed to provide engineering excellence in comfort air conditioning and industrial cooling with a superior combination of energy saving, performance, application fl ex-ibility, ease of service & maintenance and ability to withstand extreme ambient temperatures. These units can be combined with a wide variety of evaporator coils and blower packages to provide quite and dependable comfort. These units can be installed on a roof tops or at ground level.

The ACCL series are designed to use environmental friendly HFC R-407c refrigerant. HFC R-407c has zero ozone depletion zeotropic blends of HFC refrigerants. It closely matches the properties of R-22 and used in many air conditioning applications.

Scroll Compressor:

The scroll compressors are consists of two involutes or Archimedean spirals (Figure-1). One spiral is positioned inside the other to form a series of crescent-shaped pockets. During compression the upper spiral remains stationary and the lower one, being eccentrically mounted on the drive sha� , describes an orbital rather than a simple rotary motion.

INTRODUCTION

How a Scroll Compressor works:

Compression in the scroll is created by the interaction of an orbiting spiral and a stationary spiral. 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 all times, resulting in nearly continuous suction and discharge.

FIGURE- 1


5

INTRODUCTION

Refrigerant enters the compressor at the suction connection and fl ows around the motor’s housing and enters at the bot-tom 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. A� er that the refrigerant enters the scroll elements.

Semi-hermetic Compressor:

These Semi hermetic reciprocating compressors are accessible –hermetic type. Compressor and motor are enclosed in a hermetically sealed housing, without sha� seal. The compressors are equipped with an oil sight glass through which the oil quantity and its conditions in the crankcase can be observed. These compressors can be disassembled in the fi eld for service.

Refrigerant-cooled motor –compressors have an oil pressure lubrication system. This system is supplied by a positive displacement oil pump, working in either direction. It is protected by a screen and is made accessible for quick oil pressure checking by a Schrader check valve. The use of oil pressure control safeguards the lubrication system. These compressors can be provided with capacity control (optional). The use of unloading provides optimal part load capacities.

STANDARD SPECIFICATIONS, OPTIONS & ACCESSORIES

H. MICROPROCESSOR CONTROLLER

These condensing units are provided with a microprocessor control board incorporating the following features:

BALANCE LOADING OF COMPRESSORS : The unit’s electronic control automatically operates lead/lag sequence of compressors. This is to load the compressors evenly over long periods of operation. If required however, compressor 1 can also be set to always lead. In this case, compressor 1 always starts first and stops last. (Selectable through dip switch setting on control board).

PUMP DOWN FUNCTION: In units equipped with pump down system, the controller provides the time delay between solenoid’s opening and compressor starting to equalize the pressure in the system necessary for compressor to startup. (Selectable through dip switch setting on control board).

COMPRESSOR ANTI-RECYCLING PROTECTION: The controller has a built-in 3 minutes minimum off timer for com-pressor. This is for compressor protection in case of accidental manual re-set or immediate re-cycling of thermostat due to load demand.

COMPRESSOR LOCK-OUT FUNCTION: If any of the unit’s safety control trips due to abnormal conditions, the electronic controls locks out the compressor after a pre-determined timing preventing a re-start unless attended by a qualified service technician. The unit can be re-started through thermostat re-set after ensuring safe system conditions.

FAULT DIAGNOSTICS: In case of system fault, LED’s on the board emits a flashing signal indicating where the fault is. This is to guide the service technician in identifying the fault.

DIGITAL I/O’s: The unit’s control board is compatible to operate with a DDC controller or any standard 24V A.C. ther-mostat commercially available.

SEQUENTIAL CONTROL: With input signals from the thermostat, the motors in the equipment is started in sequential order: supply fan – condenser fan – compressor; at a pre-determined timings.

I. COMPRESSOR OVER LOAD PROTECTOR

The compressors has built-in thermal protector for its protection against high winding temperatures. Motor starter control is equipped with an external overload relay as an additional protection against overload.

J. UNDER VOLTAGE MONITOR (UVM)

This device protects the motors in the unit from faults such as; under or over voltage, unbalance & phase reversal of the power supply. When the device sensed such faults, it will cut-off the supply in the control circuit thereby cutting off power to the motors. The voltage monitor will re-set automatically when power is brought back to it’s normal conditions.

K. CRANKCASE HEATERS

Each compressor has crankcase heater. The compressor crankcase heater is always on when the compressor is de- energized. This protects the system against refrigerant migration, oil dilution and potential compressor failure.

L. FILTER DRIER

Refrigerant circuits are kept free of harmful moisture, sludge, acids and oil contaminating particles by the fi lter drier. Cartridge (sealed type) is standard for model ACCL020 - ACCL055 and for all other models replaceable core fi lter drier is provided.

M. SIGHT GLASS

Moisture indicating sight glass (supplied loose) to be installed in liquid line in the fi eld. Easy to read color indicator shows moisture contents and provides a mean for checking the system refrigerant charge.

OPTIONS & ACCESSORIES

A. CAPACITY CONTROL

On semi-hermetic compressors, capacity control is achieved by cycling compressors on /off and cylinder unloading. The use of unloading provides good part load capacities.

B. HOT GAS BYPASS CONTROL

Hot gas bypass is available as an option on the lead circuit to permit operation of the system down to 80% of its unloaded capacity. Under low ambient condition, it controls temperature by eliminating the need to cycle the compressor on and off , ensuring narrow temperature swing and lengthen the life span of the compressor.

C. ADVANCE MICROPROCESSOR

Advance microprocessor control can be off ered to achieve precise control and safety functions of the condensing units. Microprocessor is simple to use, push button keyboard allows to access the operating conditions, control set points and alarm history clearly displayed on a multi-line backed illuminated LCD panel. Also it’s compatible with building manage- ment system and adoptable to LON protocol.

D. FAN CYCLE SWITCH HEAD PRESSURE CONTROL (FCS)

The capacity of air-cooled condensers varies with the diff erence between condensing temperature and condenser entering air temperate (ambient temperature). It increases as this diff erence increases. For a given capacity, a drop in the ambient temperature will lower the condensing temperatures and if the ambient temperature drops below a given limit, head pres-sure control is required.

Control shall be set for a minimum of 95°F (35°C) saturated refrigerant condensing temperature, or to suit the specifi ed application.

E. PUMP DOWN SOLENOID VALVE (PDS)

A pump down solenoid valve may be installed in the liquid line. When the room thermostat is satisfi ed, the valve closes and the compressor continues to run until a substantial portion of the refrigerant has been pumped out from the evaporator. The low-pressure switch will cycle off the compressor at a predetermined evaporator pressure.

F. ADJUSTABLE HIGH PRESSURE SWITCH (HPS)

Field adjustable high pressure switch provides safety protection in the case of excessive discharge pressure. Typical factory pressure settings are shown in table below.

G. ADJUSTABLE LOW PRESSURE SWITCH (LPS)

Field adjustable low pressure switch provides safety protection in the case of low suction pressure and loss of refrigerant charge. Typical factory pressure settings are shown in table below.

H. CIRCUIT BREAKER

Protect against compressor & condenser fans branch circuit fault. When tripped (Manually or automatically), the breaker opens the power supply to the compressor and control circuit through auxiliary contacts.

I. PRESSURE GAUGES

Suction, discharge and oil (semi hermetic compressor only) pressure gauges.

J. DISCHARGE LINE MUFFLERS

Discharge line muffl ers are installed to eliminate noise due to refrigerant pulsation.

INSTALLATION & START-UP INSTRUCTIONS

SAFETY CONSIDERATIONS

Improper installation, service, maintenance or use can cause explosion, fi re, electrical shock or other conditions which may cause personal injury or property damage. Check with your nearest GE dealer/sales offi ce for information or assistance. Warning: Before installation or servicing the system, always turn off main power supply. Electrical shock can cause personal injury or death.

SCROLL COMPRESSOR ROTATION

Scroll compressors are designed to operate in single direction only. Hence, care has to be taken to ensure correct rotation when the system is operated. Verifi cation of correct rotation is by observing that the suction pressure drops and discharge pressure rises when compressor run. Reverse rotation results in abnormal sound, as well as, substantially low current draw and by interchanging power supply wire L1 & L3 will correct this problem.

INSTALLATIONSTEP-1: Check equipment and job site

Unpack unit and move to fi nal location taking care not to damage the unit. Remove screws holding the unit to wooden pallet and a� er removing wooden pallet, refi x the screws.

STEP- 2: Installation on a solid, level mounting pad

When installing, allow suffi cient space for airfl ow clearance, wiring, refrigerant piping and service. Allow proper clearance (refer to installation clearance diagram) all around and no obstruction above unit for proper airfl ow. Double the service access when multiple units are installed at one location. On roo� op applications, locate unit at least 6” (152 mm) above roof surface. Place unit above a load-bearing wall, isolate unit and piping set from structure. Use 4”x4”x1” thick rubber/cork mounting pads. Arrange supporting members to adequately support unit and minimize transmission of vibration to building.

STEP-3: Piping connections

Outdoor units should be connected to indoor units using fi eld-supplied piping of refrigerant grade and correct size. The liquid and suction line diameters can be determined from the physical data table. For piping requirements beyond 50 � (15.24 m), obtain information from your nearest GE dealer/sales offi ce.

It is advisable to size piping according to recommended ASHRAE methods. Install piping according to refrigeration standard practice. Run refrigerant pipes as directly as possible, avoiding unnecessary turns and bends. Install refrigerant pipes care-fully to prevent damaging the suction pipe insulation and vibration transmission to the structure.

Compressors are already charged with the required amount of lubricant. There is no need to charge in the fi eld. Make sure that no air & moisture enter the system as easter oil are hygroscopic in nature. The whole system should be leak tested and evacuated before charging the refrigerant.

Outdoor unit connected to factory matched indoor unit

Outdoor unit contains holding charge only. The correct system refrigerant charge for operation is given in the unit name-plate & physical data table when connected with up to 25 � (7.62 m) of fi eld-supplied piping. Check refrigerant charge for maximum effi ciency.

Sweat connection

Use refrigerant grade piping. Service valves are closed from factory when shipped and ready for brazing. A� er wrapping the service valve with a wet cloth, the piping set can be brazed to service valve using either silver rod or silfos rod brazing material. When brazing completed, refrigerant piping and indoor coil are now ready for leak testing. This check should also include all fi eld and factory brazed joints.

Warning: Relieve all pressure before refrigerant system repair or fi nal unit disposal to avoid personal injury or death. Use service ports and open all valves.

STEP 1: INSTALLATION

A) Please ensure power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements.

Caution: Operation of the unit on improper power supply will result in damage to the unit.

Note: Use copper wires of proper rating for all fi eld wiring.

Warning: Before servicing or installation of the unit, always TURN OFF all power to the unit. There may be more than one disconnect switch. Ensure all of them are turned off . Electrical shock can cause personal injury or death.

B) Ground & power wires

Connect power wires to terminal block per wiring diagram. Connect ground wire to the ground lug inside the control box.

C) Control wiring between outdoor & indoor unit

Use 16 gauge color-coded wire between the indoor and outdoor units (control wiring).

STEP 2: START-UP

1) Energize crank case heater for a minimum of 12 hours prior to the system start-up. To energize crank case heater only, set thermostat to OFF position and close electrical disconnect switch to the outdoor unit.

2) Fully open liquid/suction service valves.

3) Close electrical disconnect switch to energize the system.

4) Set room thermostat to desired temperature.
