OVERVIEW

The air conditioning (A/C) system transfers heat from the vehicle interior to the outside atmosphere to provide the heater assembly with dehumidified cool air. The system is a sealed, closed loop, filled with a charge weight of R134a refrigerant as the heat transfer medium. Oil is added to the refrigerant to lubricate the internal components of the air conditioning (A/C) compressor.

To accomplish the transfer of heat, the refrigerant is circulated around the system, where it passes through 2 pressure/temperature regimes. In each of the pressure/temperature regimes, the refrigerant changes state, during which process maximum heat absorption or release occurs. The low pressure/temperature regime is from the thermostatic expansion valve, through the evaporator to the air conditioning (A/C) compressor; the refrigerant decreases in pressure and temperature at the thermostatic expansion valve, then changes state from liquid to vapor in the evaporator, to absorb heat. The high pressure/temperature regime is from the air conditioning (A/C) compressor, through the condenser and receiver drier to the thermostatic expansion valve; the refrigerant increases in pressure and temperature as it passes through the air conditioning (A/C) compressor, then releases heat and changes state from vapor to liquid in the condenser.

Some vehicles may be fitted with a 4 zone climate control system. See AIR CONDITIONING .

A/C COMPRESSOR

The air conditioning (A/C) compressor circulates refrigerant around the system by compressing low pressure, low temperature vapor from the evaporator and discharging the resultant high pressure, high temperature vapor to the condenser. On 5.0L vehicles, the air conditioning (A/C) compressor is driven directly from the pulley. On 3.0L and 3.6L diesel vehicles the air conditioning (A/C) compressor is driven via an electro-magnetic clutch.

The air conditioning (A/C) compressor fitted to 3.0L TdV6 diesel vehicles is a variable displacement unit. The secondary accessory drive belt, driven by the engine crankshaft, drives the air conditioning (A/C) compressor via a pulley and an electromagnetic clutch. Operation of the clutch is controlled by a power feed from the automatic temperature control (ATC) module.

The air conditioning (A/C) compressor is a 7 cylinder swash plate unit with a minimum displacement of 1.6 cm 3 /rev (0.10 in 3 /rev) and maximum displacement of 163 cm 3 /rev (9.95 in 3 /rev). The automatic temperature control (ATC) module automatically adjusts the displacement of the air conditioning (A/C) compressor between the minimum and maximum values, to match the thermal load of the evaporator. By matching refrigerant flow and the thermal load of the evaporator, the automatic temperature control (ATC) module maintains cabin comfort while also considering fuel economy.

To protect the refrigerant system from unacceptably high pressure, a pressure relief valve is installed in the outlet side of the air conditioning (A/C) compressor. The pressure relief valve is set to open at 3.5 to 4.1 MPa (508 to 595 lbf/in 2 ) and vents excess pressure into the engine compartment. The pressure relief valve closes again when the pressure decreases to 3.1 MPa (449 lbf/in 2 ).

The clutch of the air conditioning (A/C) compressor incorporates a thermal cut-off fuse, which disconnects the power feed from the automatic temperature control (ATC) module if the temperature increases to 182 ± 5 o C (360 ± 9 o F).

The air conditioning (A/C) compressor fitted to 3.6L TdV8 diesel vehicles is a variable displacement unit. The secondary accessory drive belt, driven by the engine crankshaft, drives the air conditioning (A/C) compressor.

The air conditioning (A/C) compressor is a 7 cylinder swash plate unit with a minimum displacement of 5.5 cm 3 /rev (0.34 in 3 /rev) and maximum displacement of 171.4 cm 3 /rev (10.4 in 3 /rev). A control valve in the air conditioning (A/C) compressor automatically adjusts the displacement (i.e. flow of refrigerant), between the minimum and maximum values, to match the thermal load of the evaporator. By matching the refrigerant flow to the thermal load of the evaporator, the variable air conditioning (A/C) compressor maintains a relatively constant evaporator temperature of approximately 3 to 4 o C (37 to 39 o F).

To protect the refrigerant system from unacceptably high pressure, a pressure relief valve is installed in the outlet side of the air conditioning (A/C) compressor. The pressure relief valve is set to open at 3.5 to 4.1 MPa (508 to 595 lbf/in 2 ) and vents excess pressure into the engine compartment. The pressure relief valve closes again when the pressure decreases to 3.01 MPa (437 lbf/in 2 ).

The pulley of the air conditioning (A/C) compressor incorporates a mechanical torque limiter, which disconnects the drive plate from the compressor shaft if torque increases to a level that indicates imminent compressor seizure.

The air conditioning (A/C) compressor fitted to 5.0 V8 petrol vehicles is a variable displacement unit. The secondary accessory drive belt, driven by the engine crankshaft, drives the air conditioning (A/C) compressor via a pulley. Operation of the compressor is controlled by an electronic control valve working in conjunction with the automatic temperature control (ATC) module.

The air conditioning (A/C) compressor is a 7 cylinder swash plate unit with a minimum displacement of 1.6 cm 3 /rev (0.10 in 3 /rev) and maximum displacement of 163 cm 3 /rev (9.95 in 3 /rev). The automatic temperature control (ATC) module automatically adjusts the displacement of the air conditioning (A/C) compressor between the minimum and maximum values, to match the thermal load of the evaporator.

CONDENSER AND RECEIVER DRIER

Note. 5.0L V8 version shown other installations similar

The condenser transfers heat from the refrigerant to the surrounding air to convert the vapor from the air conditioning (A/C) compressor into a liquid. A receiver drier module, integrated onto the left-hand (LH) side of the condenser, incorporates a filter and a desiccant to remove solid impurities and moisture from the refrigerant. The receiver drier module also functions as a reservoir for liquid refrigerant, to accommodate changes of heat load at the evaporator.

The condenser is installed immediately in front of the radiator.

The condenser is classified as a sub-cooling condenser and consists of a fin and tube heat exchanger installed between two end tanks.

The receiver drier removes solid impurities and moisture from the refrigerant, and provides a reservoir for liquid refrigerant to accommodate changes of heat load at the evaporator.

The receiver drier is attached to the two stub pipes on the right end tank of the condenser. A collar, located on lands on the stub pipes and secured with a bolt, attaches the stub pipes to the receiver drier. A clamp secures the body of the receiver drier to a bracket welded to the right end tank of the condenser. The inlet and outlet ports of the receiver drier are the same size, so care must be taken to install the receiver drier the correct way round on the stub pipes; to assist with installation, the inlet port is identified with the word IN etched into the receiver drier.

Refrigerant entering the receiver drier passes through a filter and a desiccant pack, then collects in the base of the unit before flowing through the outlet stub pipe back to the condenser. The desiccant and the filter are non-serviceable; the complete unit must be replaced when a change of desiccant is required.

THERMOSTATIC EXPANSION VALVE

The thermostatic expansion valve meters the flow of refrigerant into the evaporator, to match the refrigerant flow with the heat load of the air passing through the evaporator.

The thermostatic expansion valve is a block type valve located behind the heater assembly, and attached to the inlet and outlet ports of the evaporator. The thermostatic expansion valve consists of an aluminum housing containing inlet and outlet passages. A ball and spring metering valve is installed in the inlet passage and a temperature sensor is installed in the outlet passage. The temperature sensor consists of a temperature sensitive tube connected to a diaphragm. The bottom end of the temperature sensitive tube acts on the ball of the metering valve. Pressure on top of the diaphragm is controlled by evaporator outlet temperature conducted through the temperature sensitive tube. The bottom of the diaphragm senses evaporator outlet pressure.

Liquid refrigerant flows through the metering valve into the evaporator. The restriction across the metering valve reduces the pressure and temperature of the refrigerant. The restriction also changes the liquid stream of refrigerant into a fine spray, to improve the evaporation process. As the refrigerant passes through the evaporator, it absorbs heat from the air flowing through the evaporator. The increase in temperature causes the refrigerant to vaporize and increase in pressure.

The temperature and pressure of the refrigerant leaving the evaporator act on the diaphragm and temperature sensitive tube, which regulate the metering valve opening and so control the volume of refrigerant flowing through the evaporator. The warmer the air flowing through the evaporator, the more heat available to evaporate refrigerant and thus the greater the volume of refrigerant allowed through the metering valve.

EVAPORATOR

The evaporator is installed in the heater assembly between the blower and the heater matrix, to absorb heat from the exterior or recirculated air. Low pressure, low temperature refrigerant changes from liquid to vapor in the evaporator, absorbing large quantities of heat as it changes state.

Most of the moisture in the air passing through the evaporator condenses into water, which drains out of the heater and through the floorpan, to the underside of the vehicle, through two drain tubes.

REFRIGERANT LINES

To maintain similar flow velocities around the system, the diameter of the refrigerant lines varies to suit the two pressure/temperature regimes. The larger diameters are installed in the low pressure/temperature regime and the smaller diameters are installed in the high pressure/temperature regime.

Low and high pressure charging connections are incorporated into the refrigerant lines near the front RH corner of the engine compartment.
