PERFORMANCE ANALYSIS OF VAPOUR COMPRESSION THERMOELECTRIC REFRIGERATION SYSTEM WITH NOZZLE AND DIFFUSER THROUGH INCORPORATION OF PHASE CHANGE MATERIAL

Abstract

Refrigerator has become an essential commodity rather than luxury item. It is one of the home appliance utilizing vapor compression cycle in it process. Performance of this system becomes main issue and many researches are still ongoing to evaluate and improve efficiency of the system. The impact of ongoing science and technology has created a variety of systems that can be used in producing refrigeration effect with the use of Thermoelectric module which produces energy which can be further used in generation of cooling or heating effect.

This study evaluates the influence of latent heat storage elements on the condenser temperature of a commercial household refrigerator. A standard wire and tube condenser is equipped with different heat storage elements and peltier module is placed at the evaporator. Phase change materials are used to reduce the condenser temperature as they are used to store latent heat. Peltier module increases the suction temperature of the evaporator. Nozzle is incorporated at the evaporator inlet and Diffuser at condenser inlet. Performance of this system will be analysed and cop will be estimated.
