Air Conditioning: Notes
WARNING: This page is about a different car, the 2002 Mercury Mountaineer and 2002 Ford Explorer. 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:
- A/C compressor (19D629).
- A/C condenser core (19712).
- A/C evaporator core (part of 19850 assembly).
- Suction accumulator (19C836).
- Connecting refrigerant lines.
The refrigeration system operation is controlled by the:
- Evaporator core orifice tube (19D990).
- A/C cycling switch (19E561).
- A/C compressor pressure relief valve (19D644).
- A/C high pressure cutoff switch (19D594).
The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.
The A/C cycling switch senses evaporator core pressure to control A/C compressor operation.
An A/C compressor pressure relief valve is installed in the compressor manifold and tube assembly (19D734) to protect the refrigerant system against excessively high refrigerant pressures.
An evaporator core orifice tube is installed in the condenser to evaporator line (19835) to meter the liquid refrigerant into the evaporator core.
