Fundamentals of refrigeration
Refrigeration engineering describes the removal of heat from an enclosed space which is to be cooled. In a compression refrigeration system, refrigerant flows through the four main components compressor, condenser, expansion valve and evaporator, thereby undergoing various state changes.
