Stainless steel corrugated pipe ground heat source heat exchange system and setting method thereof

Abstract

The invention discloses a stainless steel corrugated pipe ground heat source heat exchange system and a setting method thereof. The system comprises an overground heat exchange device and an underground heat exchange device, wherein the underground heat exchange device comprises a ground source hole arranged under a ground foundation and a heat exchange piece arranged in the ground source hole; the heat exchange part comprises a stable filling part and at least one heat exchange system unit, each heat exchange system unit comprises a stainless steel corrugated pipe section, a polyolefin material pipe section and a stainless steel bent pipe section; the stainless steel corrugated pipe section and the polyolefin material pipe section are arranged in parallel in the vertical direction of theground source hole; one end of the stainless steel bent pipe section is connected to the lower end of the stainless steel corrugated pipe section in a butt joint mode, and the other end is connected to the lower end of the polyolefin material tube section in a butt joint mode, and communicates with the stainless steel bent pipe section and the polyolefin material pipe section; and the stable filling piece is filled in the ground source hole, so that the sealing stability of the heat exchange system unit is achieved. According to the stainless steel corrugated pipe ground heat source heat exchange system, the heat exchange area is greatly increased, and heat exchange amount is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction tools, and more specifically relates to a stainless steel bellows geothermal source heat exchange system and a setting method thereof. Background technique [0002] The existing geothermal "source" system "pipe" generally uses PPR, PE-XDN light pipes, and some use PPR corrugated pipes, but such "material" structure, "low heat transfer coefficient", fluid pipes use PE- XDN20×2, the thermal conductivity is 0.38W / K, the existing geothermal heat exchange system has problems such as insignificant heat exchange effect and poor heat conduction effect. [0003] Chinese patent document (announcement date: September 2, 2015, announcement number: CN104880104A) discloses an underground bellows heat exchange device for a ground source heat pump heat exchange system, which belongs to the field of heat exchange equipment, especially involving underground buried pipe heat exchange Equipment, the device of t...
