공동주택에서 바닥복사냉방의 연속운전시 실내 열환경 성능 평가에 관한 해석적 연구

Abstract

In this study, the operation strategy of the radiant floor cooling at continuous cooling operation is evaluated in terms of indoor environmental conditions through simulations using the TRNSYS. North faced rooms with low cooling load condition were operated by only radiant floor cooling system by cooling storage effect and rooms were operated by dehumidification and supplementary cooling device with radiant floor cooling system if there is high cooling load for representative room like living room. An indoor thermal environment analysis showed that radiant floor cooling systems can maintain a set room temperature with the exception of hot and humid periods. In this case, fixed internal cooling load by heat gain during continuously operated for cooling. It was also found that the north room cool within the comfort range during the whole cooling period since the room does not heat up as much as other rooms.
