对自然工质HC2 90和HC1 2 70进行了在小型家用空调系统中灌注式替代HCFC2 2的循环性能实验研究 ,结果表明实验条件下两种自然工质系统的制冷量、COP和压缩机排气温度等循环性能指标均优于HCFC2 2。实验过程中两种自然工质性能稳定 ,未观察到与材料不兼容的现象 ;工质的可燃性在精心的实验操作中亦未构成困难
Experimental study on the cycle performance of natural refrigerant HC2 90 and HC1 2 70 in pot-replacing alternative HCFC2 2 in small household air-conditioners showed that the refrigerating capacity of two natural refrigerant systems, COP and compressor exhaust Cyclic performance indicators such as temperature are better than HCFC2 2. During the experiment, the properties of two natural working fluids were stable and no incompatibility with the material was observed. The flammability of the working fluid also did not cause any difficulties in the careful operation of the experiment
