原始语种摘要: This paper present the thermodynamic performance evaluation using Energy-Exergy method for cascade vapour-compression refrigeration system by using for HFO-1234yf (2, 3, 3, 3-Tetrafluoropropene) in the low temperature circuit and HFO-1234ze (trans-1, 3, 3, 3-tetrafluoroprop-1-ene) in the high temperature circuit. Both HFO refrigerants have ultra-low Global Warming Potential (GWP) with zero Ozone Depletion Potential (ODP) and comparison was made of the computed results using HFO refrigerants with HFC-134a refrigerant as possible alternative replacements in low temperature refrigeration circuit in the range evaporator temperature variation between -35oC of -50oC. A numerical computation has been carried out for calculating first law efficiency in terms of system coefficient of performance...
