Air Conditioning
AIR CONDITIONINGThe A/C refrigerant system is a clutch cycling orifice tube type. The system components are the following:
- A/C compressor
- A/C clutch
- A/C condenser core
- A/C evaporator core
- Suction accumulator
- Connecting refrigerant lines
The refrigeration system operation is controlled by the following:
- A/C evaporator core orifice
- A/C cycling switch
- A/C pressure cutoff switch
The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch. The A/C cycling switch senses pressure in the suction accumulator to control operation of the A/C compressor.
An A/C compressor pressure relief valve is installed in the A/C manifold and tube to protect the compressor against excessively high refrigerant pressures. An A/C evaporator core orifice is installed in the evaporator inlet tube to meter the liquid refrigerant into the A/C evaporator core.
