전통주택과 현대 공동주택 열적 특성 분석을 통한 분할난방시스템의 개발

??Korean people have been accustomed to live warm floor surface since long time ago by using floor heating system called Ondol. Thus, thermal environment that occupants feel in a room is effected not just indoor temperature but also floor temperature. Due to this specific life style of Korean, occupants can't feel thermal comfort in a room in the case that floor temperature is not in comfort zone although indoor temperature is in. Moreover, to adjust floor temperature that occupants feel comfortable, heating system is operated higher than general floor temperature and it could be increase energy consumption. Therefore, to solve these problems, we suggest partial radiant heating system that classified floor surface into different temperature and controlled each floor temperature at one time. The aim of this paper is to settle a concept of the partial radiant heating system and to present design process of this system.
