복합형 태양열 가열기를 이용한 태양열 제습냉방시스템의 흡습제 재생성능에 관한 연구

Abstract

The current issues in the world are energy crisis and global warming. Saving energy is needed to solve energy crisis problem. In past decade, air conditioning has been widely applied in human life especially in residential, office and industrial area such food, electronics, etc. Until now, the use of air-conditioner for improvement of dwelling place is increasing. Therefore, the electric power demand and supply of energy is also increasing. Solar dehumidification/air-conditioning system was proposed by many researchers to solve this problem. This research focuses to increase the regenerating performance. The desiccant absorbs water in the air through the dehumidification process. And through the process, the desiccant loses the absorption potential. The desiccant needs restore the absorption potential through regeneration process and it can be used for dehumidification. This study confirms regenerating performance according to the operation mode using the hybrid solar heating and according to the desiccant flow rate and flow rate of air. The paper analyzes the mass transfer rate and the heat transfer rate through the relative humidity and temperature between inlet and outlet. This is a useful information to the regeneration system of the solar dehumidification/air-conditioning.
