摘　　要：由于HFCs类制冷剂对环境产生破坏,目前替代制冷剂的发展仍在不断探索中。采用第二制冷剂系统可以减少HFCs类制冷剂的充注和泄露,同时可以改善能源利用效率。文中主要回顾国内外近20年来第二制冷剂的研究状况以及二次回路制冷系统在商业制冷、家用空调与热泵以及汽车空调等领域中的应用,并提出近年来备受关注的两相载冷剂在蓄冷空调中的应用前景。The use of HFC refrigerants in direct expansion refrigeration system gaves rise to various environmental problems. There is an increasing interest in the development and applications of alternative refrigerants. The application of secondary loop refrigeration systems is possible to reduce refrigerant charges and leakage. Moreover,it can improve energy efficiency. In this pa- per,the research achievement of secondary refrigerants and its application in commercial refrigeration, residential air conditioning or heat pumping and automobile air conditioning in the last 20 years were reviewed. And also,the prospect of two - phase fluids used in the field of cool storage air conditioning was proposed.
