摘　　要：吸湿性溶液与空气的热质交换过程既有热量的交换又有质量的交换 ,提高该过程的可逆程度是提高溶液除湿空调系统性能的重要手段。在对溶液的性质进行合理简化的基础上 ,分析了溶液与空气的热质交换过程的流量比和过程需要吸收或释放的热量 ,得到在不同工况下 ,可逆过程所要求的流量比和应该补充或带走的热量。In the heat and mass transfer process between liquid desiccant and air, the flow rate and heat inject/exhaust are both important factors to approach a reversible process. Focuses on the conditions that can meet the requirement of the reversible process. Sets up an ideal model of the desiccant solution, based on the mass balance and energy balance, by solving which the flow rate ratio and heat balance results can be obtained. Recommends the result to be used for determining parameters of the liquid desiccant.
