Outline of Final Research Achievements

In order to evaluate thermal environment, power consumption evaluation and air quality evaluation of the desiccant system, a desiccant system was built in the laboratory. In summer season, the number of floating fungus during the operation of the desiccant system was investigated, and furthermore, changes in thermal environment due to humidification and power consumption were evaluated in winter.
As a result of comparing the desiccant system and conventional air conditioning system, heating and humidification performance were confirmed. Indoor absolute humidity was larger than the outside air by about 2.0 g / kgDA.From this result, it was confirmed that no-feed water humidification was performed in winter. However, an effective reduction in power consumption was not seen. In addition, decreasing of the number of fungus was confirmed by dehumidifying ventilation system in the summer season.
