외기온도 변화에 따른 집단에너지 공동주택의 최적 열공급제어 알고리즘 개발에 관한 연구

Abstract

In the present study, optimal heat supply algorithm which minimize the heat loss through the distribution pipe line in group energy apartment was developed. Variation of heating load of group energy apartment building in accord with the outdoor air temperature was predicted by the heating load-outdoor temperature correlation. Supply water temperature and mass flow rate were controlled to minimize the heat loss through distribution pipe line. District heating apartment building located in Hwaseong city, which has 1,473 households, was selected as the object building for testing the present heat supply algorithm. Compared to the previous heat supply system, 10.4% heat loss reduction can be accomplished by employing the present method.
