摘要：
A theoretical performance analysis based on exergetic performance coefficient (EPC) criterion was carried out for a vapour compression refrigeration system for different refrigerants. The EPC criterion is defined as the ratio of exergy output to the total exergy destruction rate (or loss rate of availability). According to the results, the refrigerant R32 shows the best performance in terms of EPC among the other refrigerants (R410A, R143A, R404A and R125). The effects of temperature and pressure drops in the evaporator and condenser and of environment temperature on the exergy destructions and EPCs for the components of the vapour compression refrigeration system have been investigated in detail for the refrigerant R32.
