摘　　要：建立开式吸收式热泵内冷型吸收器实验台,以CaCl2溶液为吸收剂在该实验台上对比不同操作参数、外部参数和装置尺寸下,从HAT循环高湿排烟中回收水的性能。实验表明:提高进口溶液浓度、液气比、冷却比和降低进口溶液温度可提高水回收率;进气含湿量增加会提高水回收率,而进气温度增加会降低水回收率;吸收器高度存在最优值,此时水回收率最大。还分析了产生这些影响的原因,并从实际应用出发给出了这些参数的限制条件和使用范围。An internally-cooled absorber in the open cycle absorption heat pump experimental facility was devel- oped. It uses CaCl2 solution as the absorbent. Based on the experimental facility, a relation between the different parameters and the performances of the water recovery from the HAT cycle exhaust gas was studied. The results showed that improving the liquid-gas mass ratio, the concentration of solution, the cooling water and gas ratio, and the temperature the humidity of exhaust gas can increase water recovery rate. Reducing the temperature of exhaust gas and the temperature of solution can also increase water recovery rate. The absorber has an optimum height at which water recovery rate reaches maximum. The reasons were also given.
