On the basis of analyzing the thermodynamic properties and cycle performance of pure refrigerants, the paper optimizes their concentration while screening NARMs used in wide variable-temperature heat source. The practical applications of NARMs, such as R22/R123, R123/R125 etc., are studied in geothermal heat pump, seawater heat pump, air dehumidification system and dual-evaporator domestic refrigerator. The results show that the NARMs can match the limitation of a pinch point at the air-side exit of heat exchanger, reduce the unreasonable heat transfer temperature difference, and improve the COP of system. The above conclusion is proved by measuring the cycle performance of R12, MP39 and R11/R22 in a two-evaporator experimental system.

其次，本文在工质热物性和变工况循环性能分析基础上，筛选和优化了适应外部大变温热源约束条件的非共沸混合工质及其浓度配比；讨论了相变温差较大的非共沸混合工质（如R22/R123、R123/R125等）在地热源供热热泵、海水源供热热泵、双门冰箱和热泵空气除湿的应用，计算分析表明制冷与热泵系统采用相变温差较大的非共沸混合工质有利于弱化传热过程的&窄点&的约束，减小传热过程中的不合理温差，提高系统COP值；通过建立双蒸发温度循环系统试验装置，对R12、R22/R11和R22/R152a/R124循环性能进行实验研究，结果与理论分析一致。
