| In the view of the problem that R22 which is used in room air conditioner has high global warming potential，a low global warming potential
hydrocarbon mixed refrigerant composed of R290 and R600a at a ratio of 95%/5% was proposed to replace R22. The environmental and thermophysical properties of R22，R290，
95% R290/5% R600a were analyzed based on REFPROP 9.1 and calculated under theoretical conditions. In the R22 room air conditioner of an explosion proof laboratory，performance
tests were conducted on three refrigerants under rated cooling and heating conditions and the data were analyzed. The results show that under rated cooling conditions，the input power of
mixed refrigerant is 17.31% lower than R22，and the cooling capacity is 85.85% of R22; under rated heating conditions，the input power of mixed refrigerant is only 80.58% of R22，and
the heating capacity is 8.72% lower than R22; under the two working conditions，the coefficient of performance of the mixed refrigerant is 3.82% and 13.26% higher than that of R22，
respectively; In addition，the performance parameters of the mixed refrigerants have little difference with R290，and the coefficient of performance is slightly higher than R290，especially
under heating conditions. In summary，the R290/R600a mixed refrigerant has excellent performance and has the feasibility of replacing R22 in the room air conditioner. |
