Study of Hygrothermal Regulation Using Moisture Generated in an Interior

Abstract

Many residences with high thermal performance are equipped with sensible-heat type heating equipment that generates no moisture. To preserve air quality, therefore, such residences require ventilation at scheduled intervals, resulting in the problem of dry room interiors. Humidifiers used for simple hygrothermal regulation require approximately 150 W of electricity, encouraging additional energy consumption. In this study, we simulated a hygrothermal distribution that does not consume energy, using moisture generated by drying wet laundry in a room. There was no damage due to condensation formed on windows or other moisture condensation in the room next to the heated room.
