摘　　要：以构建的用于开式吸收式热泵的竖直管降膜吸收器实验台为基础,以价格低廉的CaCl_2溶液作为吸收剂,通过实验研究确定各参数对吸收过程中传质的影响。实验发现:提高吸收剂浓度、液气比、冷却比和吸收塔高度可增强吸收效果;气体湿度和气体温度的增加会降低吸收效果;冷却水和吸收剂的流动方向也会影响吸收效果。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。A falling film absorber in the open cycle absorption heat pump experimental facility was developed in the paper. The cheaper CaCl2 solution was used as the absorbent . The absorber was studied to analyze the key parameters impacting the performances of the absorption. The experimental results show the relation between the water recovery rate and the key parameters, such as the liquid-gas mass ratio, the concentration of absorbent, the flux of cooling water, the flowing direction of cooling water, the humidity and temperature of flue gas, the height of absorber. The reasons analysis were also given. The study can give a reference for the absorption design.
