A study on application of ventilation and air-conditioning system using desiccant material and solar thermal energy to real building-outline of system and results on system performance of field survey in summer

In recent years, various forms of highly unusual weather and record disaster consistent with global warming occur worldwide. In order to solve this problem, it will be extremely important that we will use a renewable energy more positively in buildings in future. Therefore, to promote the use of solar thermal energy in building industry, new ventilation and air-condition system used solar thermal energy for not only hot water supply but also floor heating and desiccant dehumidification was developed. The developed system was installed in a house for three years to improve the system and consider a method, which was successful. The measurement carried out in the summer of 2013 in the best condition lead us to understand the efficiency of the thermal collecting and storage system, the ventilation and air-condition system with desiccant material and floor cooling system.
