Air Conditioning: Notes

The refrigerant system components include the following:

• A/C compressor and clutch assembly
• A/C condenser core
• A/C evaporator core
• Suction accumulator
• Connecting refrigerant lines
• Evaporator core orifice

The refrigerant system incorporates an A/C compressor controlled by the PCM through an A/C clutch relay. An A/C cycling switch is used to cycle the A/C compressor off when the pressure in the low-pressure side of the refrigerant system falls below an acceptable level.

An A/C compressor pressure relief valve is installed in the A/C compressor to protect the refrigerant system against excessively high refrigerant pressures.
