Selection and Parameter Determination of Dehumidizer in Liquid Desiccant Air Conditioning System

Liquid desiccant dehumidification mechanism and dehumidifying process of CaCl2 solution and LiCl solution at different concentration and temperature have been analyzed. For the solution of dehumidification air conditioning system of office building, which located in Jinan, concentration range of CaCl2 solution with dehumidification ability ranges from 30% to 45% and temperature is below 40°C. The concentration range of LiCl solution with dehumidification ability should between 20% and 45% and temperature is below 55°C. According to the comparison of economical performance of CaCl2 solution, LiCl solution and mixture liquid (CaCl2 and LiCl), quality ratio with 1:1 of mixture liquid is better.
