Working Principle of Condenser and its Types

High side equipment: The pressure of the refrigerant in the condenser is very little that at the compressor discharge. The pressure at compressor discharge is higher than at any other part of the system. Hence the condenser and other equipment in the system between compressor discharge and expansion valve are referred to as high side equipment.

Low side valve equipment: Since the refrigerant in the evaporator is at low pressure compared to that in the condenser, the evaporator and auxiliaries between the expansion valve and the compressor intake are often referred to as low side equipment. Read more
