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 theworld. The first thing that is desired in a refrigeration cycleis increasing the Coefficient of Performance (COP). Hence,the use of methods that enhance the efficiency of thecompressor in the refrigeration cycle can help us a lot togarner this aim. The aim of this paper is to investigate theeffect of forced flow on the condenser and compressor of ahousehold refrigerator on the COP. In this experiment, arefrigerator using the R134-a refrigerant with a capacity of9 ft is used, cooling the condenser by an 110W fan. In eachexperiment, 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-134awere used for determining the thermodynamic properties atdifferent points of the system.
