摘　　要：制冷剂R290和R32是R22的主要替代物,受到了许多研究者的青睐。本文先建立了小型房间空调器制冷系统模型。然后在该模型的基础上,对R290、R32替代R22时,制冷系统性能(包括冷凝压力、蒸发压力、吸气压力、排气温度、压缩机功耗、制冷量、COP)的变化进行了研究。结果表明,R290和R32在房间空调器中替代R22有着较大的潜力。The refrigerants R290 and R32 are the main alternative of R22,and they have been favored by many researchers. Firstly,the model of room air conditioning refrigeration system is established. Then,the changes of the HAVC performance including condensing pressure,evaporating pressure,suction pressure,discharge temperature,the power consumption of the compressor,refrigerating capacity and COP,when R22 is substituted by R290 or R32,are studied by the model. The results show that R290 and R32 has much potential in the replacement of R22 in the room air-conditioners.
