Abstracts: Refrigeration may be define as a producing and maintaining temperature below surrounding temperature The system maintained at lower temperature is known as refrigerated system while equipment is used to maintain this lower temperature is known as refrigerating equipment. According to clausius statement of second law of thermodynamics to transfer heat from low temperature body to high temperature body external work must be supplied. Modification: To improve the COP of the system by use of evaporation cooling in condenser.
