Embodiment Construction

[0013] The concept of the present invention will be described below in conjunction with the accompanying drawings.

[0014] See attached figure 1 , indicating the structure of the U-shaped combined elbow: use three or more PE, PR or other hard plastic elbow fittings that can be heat-welded, and the bending angle of a single elbow fitting can be between 35° and 105°, with Homogeneous material tubes form a U-shaped combined elbow, and the outer diameter of the combined elbow is 150~300mm; insert the straight tube of the same material as the elbow into the two outlet ends of the U-shaped combined elbow, and the gap is connected by thermal welding.

[0015] See attached figure 2 , indicating the U-shaped combined elbow cage structure: use a plate with a width equal to or greater than the diameter of the combined elbow and a length equal to or greater than the total length of the combined elbow, and simmer it into a radian consistent with the outer diameter of the combined elbow ...

Abstract

The invention refers to a kind of vertical embedded pipe laying method for ground source heat pump. It uses U pipe underground vertical embedded pipe way to solve the settings of circular pipes, it includes steps of drilling, pipe embedding and backfilling; it uses two or more than two single knee and U type compound knee made up of the homogenesis material pipe as the knee part of the circular pipe. The invention solves the problem of leakage of the ground source heat pump circular pipe, and the problem of mechanical embedding.

Description

technical field [0001] The present invention relates to the laying method of the circulation ground pipeline used for working medium cooling or heating in the ground source heat pump air conditioning system; vertical laying method. Background technique [0002] Ground source heat pump is a new air-conditioning refrigeration and heating technology that emerged in the 1980s abroad. Ground source heat pumps can be divided into underground water source heat pump systems, surface water source heat pump systems and soil source heat pump systems; and ground source heat pumps can be divided into two types: horizontal buried pipe type and vertical buried pipe type. Because the vertical buried pipe construction occupies a small area, it is mostly used by people. For example, the Chinese Patent Publication No. CN1415910A, dated May 7, 2003, an invention patent titled "Underground Tube Heating and Air Conditioning System and Its Application", discloses a ...
