Refrigeration become a very important field of science and has number of applications in different field. The performance of the refrigerator depends upon the refrigerating effect. To improve refrigerating effect it is necessity to increase the difference between the evaporator temperature and surrounding air temperature where the refrigerator has to dissipate heat. In this paper temperature variation in whole year has been analyzed and observed that in the winter season a refrigerator perform best as compared to the summer season.



Coefficient of performance, refrigeration effect, condenser, evaporator, expansion valve, compressor.
