There are five main components in the climate control system:

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.
