摘　　要：基于第二类吸收式热泵原理,建立了第二类吸收式热泵关键过程的数学模型,开发出第二类吸收式热泵循环模拟计算程序,研究了蒸发温度、发生温度、冷凝温度和吸收温度对吸收式热泵主要评价指标性能系数ηCOP、循环倍率R、温升能力ΔT和放气范围ΔX的影响.结果表明:当吸收温度一定时,循环倍率随着蒸发温度的升高逐渐减小,系统的ηCOP先急剧增大,然后缓慢减小;当吸收温度一定时,循环倍率随着冷凝温度的升高逐渐升高,系统的ηCOP先缓慢减小,然后急剧减小;当蒸发温度一定时,循环倍率随着吸收温度的升高逐渐升高,系统的ηCOP先缓慢增大,然后急剧减小.Based on the principle of absorption heat transformer （AHT）, a mathematical model was established for the key process, while a calculation program was developed for the cycle simulation, so as to analyze the effects of evaporation, generation, condensation and absorption temperature on the main performance evaluation indexes of AHT, such as the coefficient of performance r/coe, the circulation ratio R, the temperature enhancement ability AT, and the deflection ratio AX, etc. Results show that, for a given absorption temperature, the circulation ratio reduces with rising evaporation temperature, while the ηCOP of system first increases sharply and then reduces slowly; for a given absorption temperature, the circulation ratio increases with rising condensation temperature, while the ηCOP of system first decreases slowly and then decreases rapidly; for a given evaporation temperature, the circulation ratio increases with rising absorption temperature, while the ηCOP of system first increases slowly and then decreases rapidly.
