Air conditioning: Notes

There are five main components in the climate control system:

• evaporator
• receiver drier
• compressor
• condenser
• expansion valve.

The system is filled with a suitable quantity of refrigerant and oil. The role of the oil is to lubricate and seal the compressor (piston and cylinder).

A fluorescent leak-tracing agent is added to the refrigerant. The leak-tracing agent makes it possible to trace leaks using UV light.
