摘　　要：R32由于具有环境性能优越,如ODP为零、GWP值小于R410A等优点,逐渐被认识到可以用于替代R410A。本文对R410A和R32的循环性能进行实验研究,结果表明,在不同的工况下,采用2种制冷剂时系统运行的压比基本相同,COP几乎相同。与R410A系统相比,R32系统的压缩机耗功略高,制冷量高,且排气温度高。总之,R32具有良好的热物性、环境性能及循环性能,具有极大的替代R410A的潜力。R32 has superior environmental performance,such as ODP is zero,GWP is less than that of R410A,etc.It has been gradually recognized to have potential to substitute R410A.Carries out the experimental study on the cycle performances of R410A and R32.The results show that the pressure ratios are almost the same,the compressor power consumption of R32 are slightly higher than that of R410A,the refrigerating capacity is slightly superior to that of R410A and their COP are very close,but the discharge temperature of R32 is higher than that of R410A under different working conditions.In a word,R32 has good thermophysical properties and friendly environmental performance,which make it as a potential alternative refrigerant to R410A.
