摘　　要：介绍了一种新型混合制冷剂的性能研究结果。这种新型混合制冷剂对臭氧层没有破坏作用,而且具有极低的全球变暖潜能值。研究结果表明,与R12相比,制冷量和输入功率均有所下降,但COP值上升,压缩机的效率提高,寿命试验表明采用该制冷剂的压缩机具有良好的可靠性。The research results of the performance of refrigerator compressor with a new mi xing refrigerant have been introduced. The new mixing refrigerant has no ODP and its GWP is very low. The results indicate that its refrigerating effect and ene rgy consumption are lower than that of R12, but its COP is higher than that of R12. At the same time, the result of life test indicates that the compressors with this mixture have good reliability.
