Abstract
Environmental Condition : Relative Humidity (50±10%) was kept constant. Variables were air temperature (25, 30, and 35℃), air velocity (<10, 25, and 100 cm/s), and heat irradiation (0, 50, and 100 kcal/m^2h). 26 kinds of room conditions were made in artificial climate chamber. A 26 year old healthy, nude male was used as subject. Experiments were made in sedentary and activity condition. Thermal sensation votes and comfort votes were made. Mean skin temperatures stood 33.5〜34.0℃ when sensation votes came to "neutral", while the subject was sedentary. They stood a little less than those temperatures when neutral, while the subject was in activity condition. Through partial calorimetry calculation, heat, balance was found in good correlation with thermal sensation votes. The maximum point of comfort votes appeared where thermal sensation vote stood at the warmer side of the neutral. Partial sensation votes of trunck region, especially shoulder blade stood in good correlation with whole body thermal sensation votes. Operative temperatures in sedentary condition when thermal sensation votes were neutral, stood 28℃. They stood 25℃ in activity condition.
