지역난방에 의한 공동주택의 외기예측

The objectives of this study are to find the optimal control method for apartment house with district heating system experimentally. An experimental facility consisting of small sized district heating system including heat exchangers and floor heating room have been built. The facility enables to compare the results of various control methods. This study have experimented about set point control method, outdoor reset control method and predictive optimal control method on the supply water temperature of heat demand side. Results show that 4.2% of outdoor reset control method, 11.6% of predictive optimal control method were able to save heating energy more than typical supply water temperature control method. And the predictive optimal control method have showed most effective method control.
