Investigating the performance of a household refrigerator considering the effect of forced air convection on the compressor and condenser of it

Household refrigerators have a major cooling share in the world. The first thing that is desired in a refrigeration cycle is increasing the Coefficient of Performance (COP). Hence, the use of methods that enhance the efficiency of the compressor in the refrigeration cycle can help us a lot to garner this aim. The aim of this paper is to investigate the effect of forced flow on the condenser and compressor of a household refrigerator on the COP. In this experiment, a refrigerator using the R134-a refrigerant with a capacity of 9 ft is used, cooling the condenser by an 110W fan. In each experiment, space contained air with a temperature of 31 C, and after turning the system on, it was gradually reduced. Also, the CATT software and Mollier Tables of R-134a were used for determining the thermodynamic properties at different points of the system.
