Abstract

Abstract: In cold environment, local radiant heating can improve thermal comfort. In this paper, the local radiant heating equipment was used to heat subjects' ankles and backs separately at an ambient temperature of 12.5°C and 14.5°C, with the radiant power of 200W, 300W and 500W. The number of subjects was 20.The subjects' thermal comfort changes were collected through a subjective questionnaire. The results show that local radiant heating can improve human thermal comfort. The effect of radiant heat source located on the back of human body is better than that on ankle. Local radiant heating in cold environment has energy saving effect.
