B-17 地域冷暖房における新しいエネルギーサービスの可能性に関する検討

抄録

District heating and cooling (DHC) is expected to be a promising energy-saving measure. However, DHC has a number of problems in relation to building-side system, for example decreases in the temperature difference between the supply and return water carrying cooling and heating energy. The main reason is that the DHC plant and air conditioning systems of buildings are separately operated. Thus, this study proposes a new energy service in which the operator of the DHC plant controls air conditioning systems at the same time. We revealed that energy conservation measures at the demand side would decreases energy consumption by 4% by using a simulation model.
