| 摘 要： | 选取典型状态点计算了空气与水或溶液进口状态相对位置不同时的热湿处理结果，依据传质效果的不同及全热换热与传质方向的异同，将空气与溶液的热湿传递过程在焓湿图上划分为A～D区，空气与水的过程分为A～C区，分析了各分区中的热湿传递特点及获得较优传质效果的流型，确定了各分区的界线。利用可及处理区域和热湿传递的分区结果分析和优化设计空气的加湿过程和溶液的再生过程，指出应将热量投入给水或溶液来获得更好的加湿效果或再生效果。

| Abstract: | The effects of heat and moisture transfer process are calculated on some typical points having different positions from the inlet in air-water or -hydroscopic solution system. Based on the effects and the direction of mass and total heat transfer as well as the correlations between them, the mass and total heat transfer process can be divided into four zones for air-hydroscopic solution（zone A—zone D）, and three zones for air-water（zone A—zone C） for air-water. The transfer characteristics for heat and moisture in different zones are analyzed, the flow pattern of better effect of mass transfer is obtained and the boundary lines between the zones are determined. The process for air humidification and solution regeneration are optimized with the help of reachable handling region as well as the results of heat and moisture transfer, indicating that heat should be put into water or solution rather than air to get better air humidification and regeneration. |
