抄録

The variation of the relative humidity in the room where the dehumidifier is operating was theoretically and experimentally investigated. In case of the closed room with constant temperature and no ventilation, the theoretical results are as follows : 1) The relative humidity decreases exponentially with time, and finally reaches the stationary value. 2) Initially, the quantity of dehumidificated water per unit time is larger than the moisture release from the interior finish, and finally becomes equal to it. 3) Large moisture release from the interior finish as plywood brings gradual decrease of humidity and higher stationary value, and small one as vinyl brings rapid decrease of it and lower stationary one. These theoretical results explains well the experimental ones. Secondly, the adsorption type dehumidifier using silicagel was operated in a small closet and the variation of relative humidity was observed. The theoretical analysis for this variation of relative humidity that is different from the case of being operated the usual type dehumidifier was performed.
