UNDERGROUND HEAT EXCHANGE SYSTEM USING PERMANENT DRAINAGE

摘要

The present invention relates to an installation structure of an underground heat exchange pipe which is capable of continuously utilizing underground water drained through a permanent drain system as a thermal source by horizontally arranging an underground heat exchange pipe on the ground by using a drain plate of the permanent drain system. The present invention provides installation structure of an underground heat exchange pipe including a drain plate (2) installed to be placed below a basement of a structure; and protrusions 21 formed on a lower surface of the drain plate (2) so that underground water flows through a gap formed between the ground and the drain plate (2) by a height of the protrusions (21), thereby forming a drain path (20), wherein the heat exchange pipe (1) is closely arranged to a transverse side surface of the drain plate, and when the underground water flows through the drain path (20), the heat exchange pipe (1) makes contact with the underground water, thereby performing heat exchange. According to the present invention, since the heat exchange pipe is installed by using the drain plate through which underground water flows, heat can be supplied to the exchange pipe through the underground water continuously input, so that the ceasing of heat supply is prevented, thereby continuously obtaining high heat exchange efficiency.
