关于恒温恒湿系统除湿的理论分析

Analysis of Dehumidification of Constant Temperature and Constant Humidity System

介绍了三种恒温恒湿系统除湿的方案:冷冻除湿、冷冻-吸收除湿、吸收-冷却除湿。通过对这三种除湿方案的理论计算和对比分析,得出吸收-冷却除湿方案是恒温恒湿系统中最佳的除湿方案,它有着显著的节能效果,而且可使系统的设备装置简便化。对于后两种方案(联合除湿),作者设想了一种在板式换热器的表面粘贴含有高分子功能材料的氯化锂吸收剂的吸收装置,利用压缩机排气高温来提供吸收剂的再生热,达到节能效果。

The paper puts forward three dehumidification projects of constant temperature and constant humiditysystem: frozen dehumidification, frozen dehumidification—absorbent dehumidification, absorbent dehumidification—cooling dehumidification. The absorbent dehumidification—cooling dehumidification is proved to be the optimaldehumidification by the calculation, which can save the energy obviously, and can make the equipment simplification.In the system of absorbent dehumidification—cooling dehumidification and frozen dehumidification —absorbentdehumidification, the paper designs a absorbent equipment which is a plate type heat-exchanger . And the lithium chlo-ride covers the surface of the equipment. The exhaust air that is discharged from compressor, which can save a lot ofenergy, supplies the regenerative heating of the lithium chloride.
