공동주택에서 바닥복사냉방의 간헐운전시 열성능 평가

Abstract

In this study, the operation strategy of the radiant floor cooling at intermittent cooling operation is evaluated in terms of indoor environmental conditions through simulations using the TRNSYS. The result of this study show that simulations on various situations while intermittently operated for cooling in an actual apartment building, the operation strategy is proposed that system and control method for cooling are varied with period. Specifically, when there are no people in the room, rooms were operated by only radiant floor cooling system by using cooling storage and people are occupied, rooms were operated by dehumidification and supplementary cooling device with radiant floor cooling system. In the intermittent cooling, it is possible to operate the radiant floor cooling without other supplementary cooling device if pre-cooling using the large thermal capacity of structure was conducted. And it has the advantage over the PAC economically if we are considering initial cost.
