摘　　要：本文开展了对一种新型近共沸混合物的整机性能实验研究,该混合物具有零ODP值和低GWP值,可作为传统工质R502甚至是R404A的长期替代物。在同一整机性能实验台上做了该工质与R502、R404A、R507A及R290的性能对比实验。实验结果表明,新工质具有低压比、低排气温度、高容积制冷量、高COP的优点,在-40℃左右的低温工况下,比现在广泛应用的R404A更具有优势。A new near-azeotropic mixed-refrigerant was experimentally investigated. This refrigerant has zero ODP and low GWP values. Experiments were carried out to compare the performance of the new refrigerant with R502, R404A, R507A, R290. The results show that at -40℃ temperature range, the new refrigerant has better performance on the pressure ratio, discharge temperature, volumetric refrigerating capacity and COP than that of the others.
