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 second type of absorption heat pump principle, the mathematical model of the second type of absorption heat pump is established, and the second type of absorption heat pump cycle simulation program is developed. The evaporation temperature, temperature, condensation temperature and absorption temperature The main evaluation index of the absorption heat pump performance coefficient ηCOP, cycle rate R, temperature rise ability ΔT and deflation range ΔX.The results show that: when the absorption temperature is constant, the cycle rate decreases with increasing evaporation temperature, the system of ηCOP firstly increases sharply and then decreases slowly; when the absorption temperature is constant, the cycle magnification increases with the increase of condensation temperature, the ηCOP of the system decreases slowly and then decreases sharply; when the evaporation temperature is constant, The magnification gradually increases with the increase of absorption temperature, and the ηCOP of the system slowly increases first and then decreases sharply.
