Abstract:

This paper reviews the achievement and development of the absorption-compression heat pump（ACHP） during the last 10 years，and four system models and choice of working fluids are introduced. As a new heat pump technology，compared with traditional heat pump systems，the ACHP system has a greater range of heating temperature and a higher coefficient of performance（COP）. Ammonia-water is widely used in the ACHP systems due to its excellent thermodynamic performance. Finally，the existing problems of ACHP systems and working fluid and its development trends are discussed.

摘要：

回顾了近十多年来有关吸收压缩式热泵的研究发展及主要研究成果，介绍了4种常见的系统模型以及国内外学者在系统工质选取上的倾向。吸收压缩式热泵系统作为一种新型的热泵技术，相比于传统的热泵系统，CAHP系统有着更大的供热温度范围和更高的能效比；同时由于优良的热力学性能，NH₃-H₂O在吸收压缩式热泵系统中被广泛使用。最后从系统和工质角度分析了吸收压缩式热泵系统存在的一些问题及可能的发展趋势，为后续的研究指明了方向。
