Many parallels can be drawn between the cooling system and the air-conditioning system. With a thorough understanding of the cooling system, air-conditioning becomes easier to comprehend.
The basic difference is that refrigerant has a much lower boiling point and goes through changes of state which produce much higher system pressures. This is why the components and servicing equipment are made to contain high pressures.
