| 摘 要： | 本文对机械压缩热泵两种工质（Ｒ２２、Ｒ１３４ａ）的操作性能进行了热力学分析和比较，探讨了影响热泵循环效率的因素．结果表明，在使用Ｒ１３４ａ作制冷剂时，其质量流量和能量消耗都较Ｒ２２低，而操作性能和循环效率都较Ｒ２２高．这对降低热泵的能量消耗，提高热泵的效率有一定的指导意义．

| Abstract: | The serviceability of two working fluids(R22, R134a) used in mechanical compressed heat pumps was analyzed and compared. The factors that affect cycle efficiency of heat pumps have been investigated. It can be found from result that R134a is a good working fluid compared with R22, because its flow rate and energy conservation is the lower, and its serviceability and cycle efficiency is higher. The research work has a better referential value to the design and application of heat pumps. |
