中高温热泵系统循环工质的研究
Research on cycle working fluids for moderate and high temperature heat pump systems
摘要：
为提高中高温热泵系统的性能，对R22/R236ea和R22/R236ea/R141b两种非共沸混合工质进行了多工况的理论计算与实验测试，结果显示采用后一种工质的系统性能优于采用前一种工质的系统，后一种工质完全可以满足中高温热泵系统的需求。

Abstract：
In order to improve performance of the systems， calculates and tests the cyclic performance of R22/R236ea and R22/R236ea/R141b in different working conditions. The results show that the performance of the system with the latter mixture is superior to that of the system with the former mixture and that the latter mixture can well meet the requirement of moderate and high temperature heat pump systems.
