Abstract: Recently, the district heating and cooling (DHC) system has attracted attention for energy saving. Although regional conduit, which contains a large amount of water, is considered as a kind of heat storage tank, an inner flow state has not been minutely analysed. In this study, by development of a regional conduit model, spatiotemporal change of internal energy is estimated. Simulation results show that the temperature change at small diameter pipe before customer receiving facilities is half of the whole temperature loss in regional conduit. This implies that optimal management of receiving flow rate is necessary.
