A/C Refrigerant System

The A/C refrigerant system is a clutch cycling orifice tube type. The system components include:
- A/C compressor
- A/C clutch
- A/C condenser core
- A/C evaporator core
- 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 transducer


A/C System:






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.

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