생활특성과 착의량에 따른 바닥복사난방 공간의 열쾌적 범위 및 에너지 사용량에 관한 연구

Abstract

Abstract - The purpose of this study is to provide the thermal comfort range according to the residential style and clothing level at radiant floor heating space, and co mpare the annual energy consumption and energy cost for each condition. Lower neutral point temperature has been stood for floor sitting style than chair sitting style, which appears that the thermal sensation w as affected by local heat transfer between floor surface and the human body. The result of research indica tes that neutral point temperature was in inverse proportion with the clothing level. It is interpreted t hat the increasing of clothing level results decrement of heat loss from human body, and is available to ach ieve same thermal comfort at lower room temperature. It was analyzed that the floor sitting style is mo re economical residential style than the chair sitting style, because the energy consumption of the floor sitt ing style is saved by 6.0% in average to compare with that of the chair sitting style. It is analyzed th at energy consumption has been decreased by 13.5% with the clothing level of 1.2 Clo than with that of 1 .0 Clo, and decreased by 18.0% than with that of 0.8 Clo, which explains that the energy saving can be achieved with the variation in life habit to increase the clothing level.
