摘　　要： 提出了水/二甘醇Ⅱ型吸收式热泵循环系统.从热力学原理出发,建立了描述该类热泵的数学模型,用实验对理论模型进行了验证,两者基本吻合.研究并分析了不同热源、热阱温度、回流比及溶液换热器传热效率对热泵性能的影响. This paper proposed an absorption heat pump cycle of the type-II using water/diglycol as the working pair. Based on the principles of thermodynamics, a mathematical model describing this heat pump was established. The theoretical model was tested experimentally, and the calculated results agreed with the experimental results. The effects of operating conditions, such as heat source and sink temperatures, reflux ratio and heat transfer effectiveness of the solution heat exchanger on the performance of the heat pump were studied and analysed.
