液体除湿空调系统的研究分析

在液体除湿过程中,空气与溶液之间发生的传热、传质作用是相互影响的,空气中的水蒸气分压力与溶液表面上的饱和蒸气压力差为两者之间的传质作用提供动力。由于除湿溶液喷淋在填料表面的同时,能够对流经填料之间的空气起到除尘过滤的作用,从而降低了空气中颗粒物的浓度,提高了进入室内空气的品质。但因空气和除湿溶液在填料表面直接接触进行传热传质,容易发生除湿空气夹带液体进入室内,因此对除湿空调系统做了湿式除尘以及泡沫夹带进行相关理论分析。

Analysis of Liquid Desiccant Air Conditioning System

In the process of liquid dehumidification,heat transfer and mass transfer between air and solution are influenced mutually.Water vapor partial pressure in the air and the saturated vapor pressure difference on the surface of the solution provides the driving force for the mass transfer between the air and solution.The desiccant solution has the effect of dust removal filter to the air between packing,while it is sprayed on the surface of the packing,and the concentration reduction of particulate matter in air,raising the indoor air quality.But for the air and dehumidification solution,the heat and mass transfer on the filler surface directly,which is prone to dehumidification air with liquid entraining into the room,therefore the wet dust removal and foam entrainment for desiccant air conditioning system are analyzed theoretically.
