Effect of liquid desiccant properties on dehumidification cycles.

Author(s) : CHEN L., LI Z.


Desiccant-based dehumidification is an alternative way to vapour compression dehumidification in air conditioning. It has several advantages including not using Freon refrigerants and driven by low grade energy such as waste heat and solar energy. In a desiccant dehumidification cycle, the properties of desiccant determine the cycle range, operating temperatures of the absorption and regeneration processes, which affect the efficiency and the operation conditions of the cycle greatly. Very little studies were carried out discussing desiccants properties' affection on desiccant cooling cycles on a uniform basis. In this paper, a simplified dehumidification cycle model is set up. Effect of desiccants properties on the cycle is discussed. Based on the discussion, a visualized method for selecting desiccant is established.
