摘  要:在热泵热水系统中 ,对新混合工质R4 17a进行了理论制冷循环分析和灌注式替代R2 2的循环性能对比试验研究 ,结果表明混合工质R4 17a的制热量稍低于R2 2 ,但性能系数COP、压缩机排气温度和功耗等循环性能指标均优于R2 2 ,实验过程中R4 17a工质性能稳定 ,运行正常 ,不需更换润滑油。In the heat pump heating system, the theoretical cycle analysis and a drop in experimental investigation on the performance of new fluid R417a as substitute of R22 were carried out. The results show that heating output of R417a is slightly less, but its power consumption decreases by about 10.58%, and COP is higher than that of R22. The discharge temperature of R417a is lower than that of R22. The system With R417a operates in a normal way and its lubricant doesn't need to change.
