Abstract
<p>Tateyama Hut of the University of Toyama is located on top of Mt. Jodo (height 2839 m). Dew is often formed at an attic and on the floor of a storeroom: especially frost is formed in spring, and meltwater has a bad influence on a wooden building. Based on the measured temperature and humidity inside the hut, we try to find the cause of dew and frost condensation. In the summer, the temperature in the attic exceeded 30 °C and the humidity was 100 % during the day. To address this, we installed an extractor fan on the roof of the attic, which resulted in a decrease in humidity from saturation levels. Later, we set up an air supply and exhaust device with a sensible heat exchanger: dew dissolved in an attic and on the floor of a storeroom: and frost in the spring reduced. We report the time sequence of both temperature and humidity and discuss the effect of the air exchange system.</p>
