Basic Refrigeration Cycle
The following figure shows the basic refrigeration cycle.
▪ Difference between discharge temperature and high pressure saturation temperature is referred to as discharge super-
heated degree.
▪ Difference between suction temperature and low pressure saturation temperature is referred to as suction superheated
degree.
▪ Difference between condenser exit temperature and high pressure saturation temperature is referred to as subcooled
degree.
Superheated degree must be calculated at the evaporator exit. This prevents wet compression. Refrigerant flow from the
evaporator must be adjusted using the expansion valve so that only superheated vapor can flow into the compressor.
