Title:
GROUND HEAT EXCHANGER TO WHICH PCM FUSION GROUT IS APPLIED AND METHOD FOR INSTALLING SAME
Document Type and Number:
WIPO Patent Application WO/2015/141878
Kind Code:
A1
Abstract:
A ground heat exchanger, to which PCM fusion grout is applied, comprises: a pile, which has a hollow portion formed at the center thereof, and which is installed in the ground; a heat exchange pipe, which contains a heat exchange medium, and which is arranged in the hollow portion of the pile; and grout which fills the space between the heat exchange pipe and the inner surface of the hollow portion, thereby performing heat exchange with the heat exchange medium, wherein the grout comprises a first grout member comprising shape stabilized phase change materials (SSPCM). Accordingly, a highly-efficient ground heat exchanger can be provided.
