Özet
The exergy efficiencies of the components (compressor I and II, condenser, evaporator and flash tank) of a two stage vapour compression refrigeration cycle were analysed with respect to evaporator and condenser temperatures for various refrigerants such a R1234ze, R1234yf, R236fa, R227ea and R134a. In the analysis, a computer program was developed by means of engineering equation solver (EES). The exergy efficiencies of components such as the evaporator, condenser, flash tank and compressor I increased while the exergy efficiency of compressor II decreased for the refrigerants used in the cycle for the evaporator temperatures ranging between -30°C to 0°C. The exergy efficiencies of the components such as compressor I and II increased while the exergy efficiency of condenser decreased, and the exergy efficiency of the evaporator stayed almost constant for the refrigerants used in the cycle for the condenser temperatures ranging between 40°C and 55°C. For all refrigerants, the highest exergy efficiencies (around 0.99) were obtained in the flash tank of the cycle while the lowest ones (around 0.15) were obtained in the condenser. © 2018 Inderscience Enterprises Ltd.
