Air Conditioning: Notes
WARNING: This page is about a different car, the 2009 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
The A/C refrigerant system is a clutch cycling orifice tube type. The system components include the:
- A/C compressor.
- A/C compressor clutch field coil.
- A/C clutch disc and hub.
- condenser core.
- evaporator core.
- suction accumulator.
- connecting refrigerant lines.
The refrigeration system operation is controlled by the:
- evaporator core orifice.
- A/C cycling switch.
- A/C pressure relief valve.
- pressure cutoff switch.
The refrigerant system incorporates an A/C compressor controlled by the PCM through an A/C clutch relay.
The A/C cycling switch senses evaporator core pressure to control A/C compressor cycling.
An A/C pressure relief valve is installed in the compressor manifold and tube assembly to protect the refrigerant system against excessively high refrigerant pressures.
An evaporator core orifice is installed in the evaporator core inlet tube to meter the liquid refrigerant into the evaporator core.
