摘　　要：随着环保要求的提升,汽车空调系统替代制冷剂的研究显得尤为重要。文章选择低GWP环保工质R1234yf和Isobutane作为R134a的替代品和R134a进行性能比较。与此同时,将和其他性能相近的工质如R407C,R410A和R507A开展热力学评估。R1234yf具有和R134a相近的单位容积制冷量,压缩机无需做出较大改动。压比和排气温度较低。R1234yf作为新一代低GWP环保类工质,是替代R134a的较好工质。With more strict regulations for environmental concerns,the next generation refrigerant study for automobile air conditioning system is necessary.In current study,the low GWP refrigerants R1234yf and Isobutane have been evaluated for performance comparison with R134a.Other refrigerants,R407C,R410A and R507A are also investigated for performance evaluation.It can be found that R1234yf has close unit volume cooling capacity to R134a and there is no need for modification for compressor.It is highly recommended R1234yf as a good R134a alternative among the refrigerants investigated in this paper.
