A/C System - Manual

The A/C refrigerant system is a clutch cycling orifice tube type. The system components are:
^ A/C compressor.
^ A/C clutch.
^ A/C condenser core.
^ A/C evaporator core.
^ suction accumulator/drier.
^ connecting refrigerant lines.

The refrigeration system operation is controlled by the:
^ A/C evaporator core orifice.
^ A/C cycling switch.
^ A/C compressor pressure relief valve.
^ A/C pressure cut-off switch.

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.

The A/C cycling switch senses A/C evaporator core pressure to control A/C compressor operation.

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

An A/C evaporator core orifice is installed in the A/C evaporator core inlet tube to meter the liquid refrigerant into the A/C evaporator core.
