Abstract: Refrigeration is the process of removing heat from a substance under controlled condition. Process consist of reduction of heat and maintaining the temperature of body below the general temperature of its surrounding. Refrigeration is a device which is used for cooling of food product in domestic and commercial application. For utilization of heating and cooling purpose used of vapour compression refrigeration system (VCRS) is done. The paper focus on determining the value of coefficient of performance (COP) of the refrigerator by using refrigerant. Refrigerant is substance or mixture used for absorbing heat from the environment and provide refrigeration or air conditioning when combine with other components and subsequently reject that heat from the system. They are usually in fluid state. But in most cycle it undergoes phase transition from a liquid to gas and back again. VCRS consist of four stages i. e. (expansion, compression, condensation and evaporation) which helps to carry heat medium for refrigeration. COP has to be calculate for finding good refrigerant in refrigeration system. Refrigerant should have low boiling point, high critical temperature, and high latent heat of vaporization which makes these properties as a good refrigerant. Determination of the value of COP is done on VCRS by using refrigerant in normal temperature and pressure condition.
