Air Conditioning: Notes
WARNING: This page is about a different car, the 2007 Ford Pickup, 2007 Ford F550 Super Duty, 2007 Ford F450 Super Duty, and 2007 Ford Cab & Chassis. 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 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.
