Performance Analysis of Vapour Compression Refrigeration System by using Azeotrops

The work has been carried out to evaluate the various thermodynamic performance parameters at different Evaporator & Condenser temperature for 0.5 tone of refrigeration cooling capacity with azeotropes as a refrigerants. In the present study R-500(R-12/R-152),R-502(R-22/R115),R-503(R-23/R-13),R504(R-32/R-115),R-407C(R-32/125/134a-23/25/52), R-410A (R-32/125-50/50), R-507A ( R-125/143a – 50/50) have been tried in place of R-22. The mixture of Refrigerant were chosen on the basis of available database of thermodynamic properties is generated using experimental and analytical data’s based on the Refrigeration equation available in refrigeration data book. The single stage vapour compression refrigeration cycle calculation have been performed to ascertain the suitability of these alternate refrigerants as substitute refrigerants for which shall be phased out in near future. This analysis will be helpful to determine the selection of components (Compressor, Condenser, Evaporator and Throttle valve.) used in commercial refrigeration applications.
