Problems solved by technology

[0003] The ground source heat pump system has the following problems: First, the burial of its underground heat exchange system (buried pipe system) will occupy a large amount of land, which will add more difficulties to the areas where the land is already tight, and it is not easy to promote it on a large scale; The initial investment in the construction of the heat pump system is large, and the drilling construction cost of the buried pipe accounts for a considerable proportion; the third is that the construction quality of the buried pipe cannot be effectively guaranteed in the current conventional bored pipe

Embodiment Construction

[0025] The ground source heat pump buried pipe system of the present invention buried in the enclosure structure of the underground diaphragm wall will be described in detail below with reference to the accompanying drawings.

[0026] The general underground diaphragm wall enclosure structure 1 can be defined as: using various digging machines, with the help of the function of the mud wall, digging out a narrow and deep trench underground, and pouring appropriate materials in it to form an anti-corrosion trench. A continuous underground wall with seepage (water), soil retaining and load-bearing functions.

[0027] Usually the underground diaphragm wall enclosure structure 1 is mainly used for: 1. water conservancy and hydropower, open-pit mines and tailings dams (pools) and anti-seepage walls of environmental protection projects; 2. building basements (foundation pits); 3. underground structures ( Such as underground railways, underground roads, underground parking lots and un...

Abstract

The invention discloses a ground source heat pump system with a ground heat exchanger buried in a diaphragm wall retaining structure, comprising the ground heat exchanger (2) and the diaphragm wall retaining structure (1); wherein, the ground heat exchanger (2) is pre-buried in the diaphragm wall retaining structure (1); both ends of the ground heat exchanger (2) are exposed out of the diaphragm wall retaining structure (1). The system occupies less floor area and features low construction cost and good heat transfer effect.

Description

technical field [0001] The invention relates to a ground source heat pump buried pipe system, in particular to a ground source heat pump buried pipe system buried in an underground continuous wall enclosure structure. Background technique [0002] Ground source heat pump is a high-efficiency energy-saving air conditioning system that uses underground shallow geothermal resources (also known as geothermal energy) for both heating and cooling. The ground source heat pump realizes the transfer of heat energy from low temperature to high temperature by inputting a small amount of high-grade energy (such as electric energy). The ground energy is used as the heat source of heat pump heating in winter and the cold source of air conditioning in summer, that is, in winter, the heat in the ground energy is "taken" out, and after raising the temperature, it is used for indoor heating; in summer, the heat in the room is taken out and released Go to the ground energy. Usually the groun...
