通过理论分析、压缩机的量热试验及空调器整机性能试验，说明了Ｒ３２／Ｒ１３４ａ混合工质在一定的配比范围内是空调器中Ｒ２２的灌注式替代工质。
Through the theoretical analysis, the calorimeter test of the compressor and the performance test of the air conditioner, it shows that the R32 / R134a mixed working medium is a kind of pouring alternative medium for R22 in the air conditioner in a certain proportion.
