原始语种摘要: This paper present the thermodynamic performance evaluation of two stage cascade vapour compression refrigeration system using Energy-Exergy method. The comparison were made of three systems of stage cascade vapour compression refrigeration in terms of their thermodynamic performances such as first law efficiency in terms of system overall coefficient of performance (COPOverall) and second law efficiency in terms of exergetic efficiency and system exergy destruction ratio (EDR_system) which is the based on exergy of fuel or exergy of product. The comparison were made for above three systems because system-1 (consist of HFO-1234ze in high temperature circuit and R134a in low temperature circuit) while System-2 (consist of HFO-1234ze in high temperature circuit and R1234yf in low...
