Abstract |
To those who spend most time within a room, comfortable indoor environment is a very critical element to job performance and health. The comfort technology, which is for enhancing comfort in human living, relates with various factors to ensure human activities ef-ficient, comfortabe, safe and satisfactory. Experiments were performed in environmental chamber. Experimental conditions were combinations from three temperatures of 18, 22 and 26C, and two relative humidity levels of 45 and 60%. Air-flow was controlled to 0.1 m/s through the experiment. Four male and four female university students participated in the experiments. They had normal blood pressure and their body temperature was under 37℃. From the experiments for evaluating thermal sensation to the air-heating conditions, relation-ships among TSV, CSV, SET*, PMV were analyzed. Results can be summarized as follow-ings; Thermal neutrality SET* of man and female was 24.8℃. In air-heating condition, SET* values for thermal comfort zone were 23.0~26.5℃. These values were higher than the values from ASHRAE. |
