摘要
本文分析了水/二甘醇、水/乙二醇高温吸收式热泵工作原理及过程,并对热泵循环进行了变工况计算模拟,得出了系统性能系数COP,循环(火用)效率η,温升△T及溶液循环倍率FR随供热温度T_g,热阱温度T_c,浓溶液浓度x_3及放气范围△x的变化规律。
The Principles and Process of high temperature absorption heat pump with water/diglycol and water/glycol as mediums have been analyzed in this work. The heat pump cylces at different operation conditions are simulated by the mathmatic model. The system performance coefficient, the cycle energy efficience, the temperature boost, the solution circulation ratio related to the heat source temperature, the heat sink temperature, the concentration of concentrated solution, and the range of vent have been exammed.
