利用模型研究空气与水或吸湿溶液热湿传递过程的特性,得到两个相互独立的驱动力——焓差驱动力和相对湿度差驱动力。根据两驱动力的关系在焓湿图上确定了一个由空气进口等焓线、湿空气饱和线(或溶液等浓度线)、空气与水或溶液进口状态连线围成的三角形区域,不论流型、传热传质系数或流量如何变化,空气出口状态只能在该区域内变化,即为空气与水或吸湿溶液热湿传递过程的可及处理区域。应用可及处理区域分析了文献中除湿实验、再生实验的热湿处理结果,明确了实验装置所处的性能水平。
The model was used to study the characteristics of heat and moisture transfer between air and water or hygroscopic solution. Two driving forces, enthalpy difference driving force and driving force of relative humidity difference, were obtained. According to the relationship between the two driving forces, a triangular region surrounded by enthalpy lines such as air inlet, saturated lines of wet air (or solution concentration lines), air and water or solution inlet states is determined on the enthalpy diagram, regardless of flow Type, heat and mass transfer coefficient or how the flow changes, the state of the air outlet can only change within the region, that is, air and water or moisture solution heat transfer process accessible area. The results of heat and moisture treatment of dehumidification experiments and regeneration experiments in the literature are analyzed in the areas of application and treatment, and the performance level of the experimental device is clearly defined.
