Abstract
A novel air dehumidifier using HCOOK solution has experimentally been tested to be feasible and effective. Air flow rate and its relative humidity have big impacts on air dehumidification. The decrease of relative humidity could be over 25% using a strong HCOOK solution to desiccate highly humid air (>75% RH). However, it does not dehumidify efficiently the air with a relative humidity lower than 43% even if strong HCOOK desiccant solution is used. In highly humid spaces, such as bathroom, swimming pool, or kitchen, air dehumidification using a liquid desiccant is very efficient.
