The purpose of this study was to find the effect of thermal sensation scale to calculate an accetable temperature range. ASHRAE Std. 55 addressed "Thermal comfort is that condition of mind which expresses satisfaction with the thermal environment" It means that it so difficult to measure the thermal comfort. Because, It is the research about human mind. Until the present, many reasearch used ASHRAE 7-point Thermal Sensation Vote scale to measure the thermal comfort. In this paper, same temperature conditions were evaluated by 7-point scale and 9-point scale, and acceptable temperature ranges were calculated by each scale and then compared by.
The results of this study were as follows; The acceptable temperature range was narrower in using 9-point scale and 80% of acceptable range which was calculated by 9-point scale was lower than that was calculated by 7-point scale about 0.7℃.
