Thermodynamic Performance Evaluation of Single Stage Vapour Compression System Equipped with Liquid Vapour Heat Exchanger Using Eight Ecofriendly Refrigerants for Reducing Global Warming

This paper presents a detailed theoretical exergy analysis of single stage vapour compression refrigeration system using refrigerants R-410A, R-407C, R-600A, R-290, R-32, R-134A, HFO-1234yf, HFO-1234ze. For exergy analysis a mathematical computational model is developed in engineering equation solver (EES) for calculating coefficient of performance (COP), exergetic efficiency, exergy destruction ratio (EDR) and the effect of evaporator temp, effectiveness of liquid vapour heat exchanger on COP, EDR, and exergetic efficiency is presented. Among the refrigerants taken HFO-1234yf and HFO-1234ze shows the promising results because of ultra low global warming potential (GWP) and zero ozone depletion potential (ODP).
