UNDERGROUND HEAT EXCHANGE SYSTEM USING UNDERGROUND CONTINUOUS WALL

摘要

PROBLEM TO BE SOLVED: To provide an efficient underground heat exchange system in which a new installation space for heat exchange pipes and an excavation work are not required by utilizing an underground continuous wall and an arrangement of the heat exchange pipes can be freely set corresponding to a required heat exchange capacity. SOLUTION: In the underground continuous wall 11 using a steel member 18, a feed pipe 15a of hot water and a cold water return pipe 15b as one example of a heating medium which can heat-exchange with a heat utilizing facility on the ground such as a radiation device 13 installed on a road surface 13a are installed through closed spaces 22 (water tank) of the steel member 18 provided at every predetermined intervals in a wall direction. By circulating hot water through the feed pipe 15a, the heating medium is directly or indirectly contacted with the steel member and the heat of the heating medium is accumulated on the steel member and the ground 1 or the heat possessed by the steel member and the ground 1 is taken to the heating medium. Thereby, the underground heat and the heat of the heating medium are exchanged. COPYRIGHT: (C)2004,JPO
