The refrigerant is a heat carrying medium which during their cycle (i.e. compression, condensation, expansion and evaporation) in the refrigeration system absorbs heat from a low temperature system and discards the heat so absorbed to a higher temperature system. The suitability of a refrigerant for a certain application is determined by its physical, thermodynamic, chemical properties and by various practical factors. There is no one refrigerant which can be used for all types of application

Hence, a refrigerant is chosen which has greater advantages and less disadvantages. Properties of good refrigerants are low boiling point, high critical temperature, high latent heat of vaporization, low cost .The standard comparison of refrigerants, as used in the refrigeration industry, is based on an evaporating temperature of -15oC and a condensing temperature of +30oC. This paper deals with experimental investigation by using R600a, R-22, and R-12 refrigerant in vapour compression refrigeration system and to calculate theoretically the value of Coefficient of Performance. This Comparison has done on vapour compression refrigeration system and compares COP with existing refrigerant at same load in normal temperature and Pressure condition.
