Outline of Final Research Achievements

In order to make a framework to predict dryness sensation from conditions of indoor thermal environments, models to predict heat and moisture transfer in and around skin, eye and airway were developed, and subject experiments were conducted to measure physiological and psychological responses of human to thermal environmental conditions inducing dryness of skin and mucous membranes. As the results, the surface temperature and moisture state of skin, eyes and airway calculated by the developed models agreed fairly well with the measured results obtained in the subject experiments. On the other hand, the psychological responses to an extremely low humidity conditions were not distinct. Therefore it was shown that the framework to evaluate the indoor thermal environments without dryness sensation should be based not on sensation of dryness, which was firstly assumed, but on the physiological variables of moisture state of skin and mucous membranes.
