近年来，在蒸汽压缩制冷系统中，尤其是在热泵中，使用混合物作为工质受到越来越多的关注。本文从不同类型的二元溶液的理论背景开始，解释为什么某些混合物适用于各种应用；然后介绍多组分混合物的行为。然后根据公布的试验结果，描述了可能的溶液的特殊影响，例如不混溶液体、共沸混合物，尤其是卤代烃的非共沸混合物。本文回顾了预测性能和实验观测性能之间不一致的可能原因，并提出了系统改进建议，以获得最大效益。 单位:双引文:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

In recent years, increasing attention has been devoted to using mixtures as working fluids in vapor compression refrigeration systems, especially in heat pumps. This paper begins with theoretical background on the different types of binary solutions, to explain why certain mixtures are useful for various applications; it will, then introduce the behavior of multicomponent mixtures. The special impact of possible solutions, such as immiscible liquids, azeotropic mixtures, and especially nonazeotropic mixtures of halogenated hydrocarbons, is then described based on published test results. A review is presented of possible reasons for the disagreement between predicted and experimentally observed performance, followed by suggested system modifications to obtain maximum benefit.Units: Dual
