Study on the Dehumidification and Indoor Air Cleaning Performance of Rotary Desiccant Rotor

Abstract With the improvements of living standards, people’s demand for indoor environment is not only confined to thermal comfort, but also spread to health-oriented aspects. However, the indoor environment in major parts of China face challenges of atmospheric pollutions and building energy consumptions. In the present paper, a novel adsorption ventilation system which combines air thermal conditioning and indoor air cleaning was proposed. The proposed system utilizes the moisture and gaseous pollution adsorption potential of desiccant material to realize indoor air dehumidification and cleaning, and aims at improving indoor air quality and reducing energy consumption of building ventilation. Literature review study on the performance of desiccant rotor commonly used as adsorption equipment was conducted. An experimental system was designed and developed to validate the performance of desiccant rotor and investigate the key influence parameters. A system which combine the desiccant rotor with heat pump was discussed.
