为了寻找既具有良好的循环性能又具有环境友好性的替代制冷剂，本研究以R32和R290作为替代工质，与R22和R410 A进行对比。在一台小型分体式家用空调器上，采用焓法对一台直径为5 mm的翅片管换热器进行了实验研究。结果表明，在额定冷却条件下，R32和R290的COP分别比R22高26.8%和20.4%，比R410 A高7.3%和2.1%。在额定加热条件下，R32和R290的COPHR均比R22高11.0%，比R410 A高5.3%。R290和R32的系统在制热模式下与R22和R410 A的系统具有相似的能力，但在制冷模式下的能力差异较大。从充注量的角度考虑，R290是小型翅片管换热器空调器中性能最优的上级替代制冷剂。
In order to find alternative refrigerants which exhibit both favorable cycle performance and environmental friendliness, R32 and R290 were utilized to contrast to R22 and R410A as substitutes in the present study. The experiments were conducted with a 5 mm finned tube heat exchanger based on the enthalpy method in a small split household air conditioner. The results showed that in nominal cooling conditions, the COPRof R32 and R290 were 26.8% and 20.4% higher than R22, 7.3% and 2.1% higher than R410A. And in nominal heating conditions, the COPHRof R32 and R290 were both 11.0% higher than R22, 5.3% higher than R410A. The systems with R290 and R32 have similar capacities to that with R22 and R410A in heating mode, but a relatively huge difference of capacities in cooling mode. In consideration of charge amount, R290 could be considered as the most superior alternative refrigerant in air conditioners with the small finned tube heat exchanger.
