Experimental investigations of vapour compression refrigeration system using electrohydrodynamic (E.H.D.) effect

Abstract

The Vapour compression refrigeration system is most commonly used in a domestic refrigerator, Cold storage, and other cooling devices such as air conditioning. For the improvement in the performance of the vapor compression refrigeration cycle, several improvement methods have been successfully used. Such techniques are classified as Passive, Active, and combined active and passive techniques. In passive techniques, fluid additives or some special geometrical shape such as rough surface, inserts, fins, etc., is required. On the contrary, an active technique requires some external force in the form of electric field, acoustic, or vibrations. In the present research, the electrohydrodynamic (E.H.D.) effect is used to enhance the performance of a vapour compression refrigeration system. In this study, the condenser of the vapour compression refrigeration system is experimentally evaluated for the impact of an electrical body force. By evaluating the result of C.O.P with and without the electrohydrodynamic effect. It is found that the theoretical C.O.P. of vapour compression refrigeration system increases by 10% with the application of the electrohydrodynamic effect.
