NH3-NaSCN吸收-压缩式热泵热力学性能研究

摘要

Absorption - compression heat pumps were well accepted for industrial waste heat recovery. An investigation on NH3 - NaSCN absorption - compression heat pumps was carried out based on the first and second laws of thermodynamics and the effects of the heating temperature, heat source temperature and compression ratio on the performance were obtained, which provided a theoretical base for the optimization of NH3 -NaSCN absorption -compression heat pumps.%吸收-压缩式热泵在工业余热回收利用中有着非常广泛的应用前景。文章基于热力学第一和第二定律对以NH3-NaSCN为工质的吸收一压缩式热泵进行了热力计算和理论分析，得到了NH3-NaSCN吸收一压缩式热泵的热力学性能随供热温度、热源温度及压缩比的变化规律。本文的工作为优化设计NH3-NaSCN吸收-压缩式热泵提供了理论依据。
