摘　　要：研究回收排风潜能的新型液体除湿空调装置,通过回收排风潜能,降低系统中直接蒸发喷淋水的温度,使除湿处理后的空调送风得到降温加湿,达到空调房间所要求的送风温度.同时,空调排风的利用降低了再生空气介质的温度和含湿量,提高了再生溶液的浓度.实验证明,在上海湿热的夏季里,该装置用温度为80℃左右的热源驱动,可以直接获得18℃、相对湿度90%的空调送风;系统的热力系数为0.8,电效比为8.6,节能效果明显.A new liquid desiccant air conditioning device is introduced, which utilizes the potential of discharged air to lower the temperature of the direct-evaporating sprayed water in the system, and to humidify and reduce the temperature of the dehumidified supplying air, and leads to meet the requirement of the supplying temperature of air-conditioned chamber. At the same time, the use of the potential of discharged air drops the temperature and humidity of regenerating air and as a result, a denser regenerated solution is attained. The results of experiment prove that in the sweltering summer of Shanghai, the temperature of heat source is 80 ℃, and the temperature and relative moisture of supplying air handled are respectively 19℃ and 90 % ; the COP of the system is about 0. 8 and the EER about 8.6. So the system bears a satisfactory energy-saving ability.
