COMPARATIVE STUDY OF EXERGY LOSS OF REFRIGERANTS DURING CONDENSATION PROCESS OF VCR CYCLE
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 5, Issue 4
Abstract
In this proposed work, analysis of change in exergy of various refrigerants who are having zero ozone depletion potential based on their properties is made by comparing the required outputs. The study is based on second law of thermodynamics in which the relation between exergy and Carnot COP of a VCR cycle is established to optimize the properties like pressure and temperatures of the specific system like condenser. The study was carried out with the starting point as the exit of compression process assuming condensation of the gaseous refrigerant without any pressure drop. Various values of change in exergy during condensation calculated for various temperatures, below saturation temperature ie. in sub cooled region of the liquid. The data plotted to obtain curves and mathematical model is proposed from data so obtained to calculate one parameter by just knowing the value of the other. Thus a relationship is establish between the degree of sub cool at the end of the condensation process to the exergy destruction for various refrigerants to compare outcome of results. In addition, a relationship between exergy drop and COP is established to optimize second law analysis of the system for different refrigerants for constant pressure condensation process in a vapour compression refrigerant cycle.
