PERFORMANCE ANALYSIS OF VCR SYSTEM WITH VARYING THE DIAMETERS OF HELICAL CONDENSER COIL BY USING R-134A REFRIGERANT
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
Vapor compression machine is a refrigerator in which the heat removed from the cold by evaporation of the refrigerant is given a thermal potential so that it can gravitate to a natural sink by compressing the vapor produced. Majority of the refrigerators works on the Vapor compression refrigeration system. The system consists of components like compressor, condenser, expansion valve and evaporator. The performance of the system depends on the performance of all the components of the system. The design of condenser plays a very important role in the performance of a vapor compression refrigeration system. Effective new designs are possible through theoretical calculations, however may fail due to the reason that the uncertainties in the formulation of heat transfer from the refrigerant inside the condenser tubes to the ambient air. Hence experimental investigations are the best in terms of optimization of certain design parameters. The main objective in the present work is an attempt is made to verify the performance of existing condenser design to helical shaped condenser design and varying the length of the helical condenser coil to verifying the effect on the performance of a domestic refrigerator capacity 165lts, R-134a as refrigerant, hermetic sealed compressor. It is expected that the helical shaped condenser installation may give optimum results. Finally it is observed that by changing the conventional design to Helical shaped condenser the performance of the refrigeration system is increased.
