Air Conditioning: Notes

The refrigerant system components include the following:

• A/C compressor and clutch assembly
• A/C condenser core
• A/C evaporator core
• Receiver/drier desiccant bag
• Connecting refrigerant lines
• Thermostatic Expansion Valve (TXV)

An A/C pressure relief valve is installed in the A/C compressor to protect the refrigerant system against excessively high refrigerant pressures.

Refrigerant flow into the evaporator core is metered by a TXV.
