Photothermal conversion regenerated desiccant sheet, desiccant element and desiccant rotor using the sheet, and air conditioning system using the element or rotor

摘要

A conventional desiccant air-conditioning system using light energy such as sunlight has a problem in the efficiency and the regeneration temperature and is not satisfactory in terms of performance. The purpose of the present invention is to provide a desiccant sheet capable of conducting the absorption and desorption of moisture by effectively utilizing the thermal energy that is obtained from light energy such as sunlight, and further to provide a desiccant element and a desiccant rotor that use the sheet, and a desiccant air-conditioning system using the desiccant element and the desiccant rotor. The purpose of the present invention is achieved by containing a moisture absorption and desorption material and a photothermal conversion material as essential components in a desiccant sheet. Here, the moisture absorption and desorption material and the photothermal conversion material are preferably in direct contact with each other in at least parts thereof, or in a state of close proximity to each other through a resin.
