Résumé

The aim of this study is to develop a new compact heat pump unit for the residential air conditioning and the hot water supply integrated with the desiccant ventilation. The climate in the summer in Japan is very humid compared with that in European countries. Therefore, a dehumidification is essential. Here, the exhaust heat of the air-conditioner is available heat source for regeneration of a desiccant wheel. In this study, a new desiccant wheel made by the paper-base containing Wakkanai siliceous shale which is a natural meso-porous material produced abundantly inthe northern part of Japan has been developed. The performance of dehumidification of this wheel was evaluated under two types of experiments, a static test and a rotating test. The results of the static test showed that this wheel could adsorb moisture repeatedly by regeneration at 40ºC air. It was confirmed that 80% of the latent heat load can be removed from the outside air from the rotating test.
