Document Type and Number:
WIPO Patent Application WO/2018/105629
Kind Code:
A1
Abstract:
Provided is a ground heat exchanger that improves heat-transfer efficiency from the earth, is smaller in size, occupies less surface area, has reduced installation costs and operation costs, and can be installed in a narrow piece of land. A large-tube horizontally-inclined convection-type ground heat exchanger according to the present invention is characterized in that: said ground heat exchanger is a straight metal tube embedded in the ground in an inclined and horizontal manner; both ends of said straight tube are respectively closed off by two end surfaces perpendicular to the long axis thereof; an upper portion of an upper end surface provided to the higher of the two end surfaces and a lower portion of a lower end surface provided to the lower of the two end surfaces are respectively provided with an upper-portion heat medium port and a lower-portion heat medium port; the cross-sectional area of the interior of said straight tube is 314 cm2 or more; the ratio of the distance and height difference between the upper end surface and the lower end surface is in the range of 3:1 to 100:1; and a concrete layer or mortar layer is provided around said straight tube.
