Abstract: Refrigeration is the process of removing heat from a low temperature reservoir. The refrigeration system use liquid refrigerant as the medium which absorbs heat from the space to be cooled. Then it reaches compressor, where it is compressed to high pressure resulting in a high temperature as well. This refrigerant is then passed through the condenser and then through expansion valve, resulted decrease in temperature and pressure, then reaches the evaporator and cycle continued. This paper was experimental investigation and provide proof that COP of a refrigerator is increased by installing the diffuser in the inlet of the compressor and by adding nano particles in to the refrigerant of the system.
