Study on the Evaluation of Thermal Comfort and Discomfort Based on Cognitive Temperature Scale of Occupants

Abstract

This paper clarifies the domain characteristics of the "not uncomfortable" state as being a result of thermal adaptation in heating rooms under two unsteady thermal environments in winter, based on the cognitive temperature scale.1. If thermal comfort descriptions by the subjects change from "uncomfortable" to "not-uncomfortable" or to "comfortable", then cognitive temperature has risen. This result was similar for thermal sensation. From this result, the existence of "not-uncomfortable" state becomes clear.2. The cognitive temperature was higher than room air temperature when described as "comfortable". Therefore, the difference between the cognitive temperature and room air temperature can be used to estimate thermal adaptation.
