Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ground source heat pump, in particular to a ground source heat exchanger installation structure and a ground source heat exchanger installation method. BACKGROUND

[0002] The ground source heat pump system takes rock-soil, underground water or surface water as low-temperature heat source, and is a heating and air conditioning system composed of a water source heat pump unit, a geothermal energy exchange system and a building internal system. According to the form of the geothermal energy exchange system, the ground source heat pump system is divided into a ground source heat pump system, an underground water ground source heat pump system and a surface water ground source heat pump system.

[0003] In actual application, the ground source heat pump heating system is mainly divided into three parts: an outdoor ground source heat exchange system, a ground source heat pump main system and an indoor terminal system. Among them, the outdoor heat exchange system needs to be buried underground. Due to the increasing shortage of land resources, in order to implement the ground source heat pump system, the outdoor heat exchange system needs to be closely combined with the building and buried under the building foundation, and enters the garage through the side wall or garage floor.

[0004] In the actual construction process, the connection mode and the wall-penetrating mode of the horizontal pipe of the outdoor ground source heat exchange system may have great differences. Due to the internal civil defense partition of the building, the inconsistent elevation, the position of the cold and heat source room and other reasons, the project design personnel cannot access the building in the layout of the horizontal pipe of the outdoor heat exchange system. Therefore, in the process of construction, due to the backfilling of the foundation pit and other construction, the horizontal pipe may be bent and collected. In order to reduce this risk, many existing methods are to abandon the part of the heat exchange hole which may affect the horizontal pipe, thereby reducing the heat exchange capacity of the outdoor heat exchange system of the ground source heat pump and reducing the proportion of renewable energy in the cold and heat source supply of the project. SUMMARY

[0005] The main purpose of the present application is to provide a ground source heat exchanger installation structure and a ground source heat exchanger installation method, so as to solve the technical problem that the horizontal pipe of the heat exchanger is easily damaged due to the backfilling of the foundation pit and other construction in the installation process of the ground source heat exchanger in the prior art.

[0006] In order to achieve the above-mentioned purpose, according to one aspect of the present application, a ground source heat exchanger installation structure comprises: a ground heat exchanger arranged outside a building body; a horizontal connecting pipe in communication with the ground heat exchanger and extending in a horizontal direction from the outside of the building body; and a cantilever beam support installed outside the building body in the horizontal direction and used for supporting the horizontal connecting pipe.

[0007] In one embodiment, the ground source heat exchanger installation structure further comprises a flexible paving layer, which is paved on the top of the cantilever beam support and used for contacting the horizontal connecting pipe.

[0008] In one embodiment, the ground source heat exchanger installation structure further comprises a horizontal through-wall pipe connected with the horizontal connecting pipe, the horizontal through-wall pipe penetrating from the outside of the building to the inside of the building.

[0009] In one embodiment, the ground source heat exchanger installation structure further comprises a sleeve pipe member penetrating the building, the horizontal through-wall pipe penetrating the building from the inside of the sleeve pipe member.

[0010] In one embodiment, the horizontal through-wall pipe is perpendicular to the horizontal connecting pipe.

[0011] In one embodiment, the horizontal connecting pipe comprises a horizontal output pipe and a horizontal return pipe, the horizontal output pipe and the horizontal return pipe being connected with the ground loop heat exchanger respectively.

[0012] According to another aspect of the present application, a ground source heat exchanger installation method is provided, comprising: S10: arranging a ground loop heat exchanger on the outside of a building; S20: connecting a horizontal connecting pipe with the ground loop heat exchanger, and extending the horizontal connecting pipe horizontally from the outside of the building; S30: arranging a cantilever beam support on the outside of the building, and supporting the cantilever beam support under the horizontal connecting pipe.

[0013] In one embodiment, it comprises: in S30, laying a flexible layer on the cantilever beam support, and contacting the flexible layer with the horizontal connecting pipe.

[0014] In one embodiment, in S20, it further comprises: penetrating a sleeve pipe member on the building, arranging the horizontal through-wall pipe connected with the horizontal connecting pipe, and penetrating the horizontal through-wall pipe from the outside of the building to the inside of the building through the sleeve pipe member.

[0015] In one embodiment, it comprises: in S30, arranging the size of the cantilever beam support according to the required support area of the horizontal connecting pipe.

[0016] When the horizontal connecting pipe connected with the ground loop heat exchanger is arranged to extend along the outside of the building, even if the outside of the building still needs to be constructed, such as pit backfilling, etc., the horizontal connecting pipe is not easily bent and damaged by the stress of the pit backfilling due to the support of the cantilever beam support under the horizontal connecting pipe, effectively protecting the horizontal connecting pipe, reducing the risk of gas collection after the horizontal connecting pipe is connected to be bent up and down, and ensuring the stable and efficient operation of the ground source heat exchanger system. In addition, the technical solution of the present application can also effectively avoid the situation that part of the ground loop heat exchanger is cancelled because the horizontal pipe cannot be connected to the building nearby.

[0024] Figure 1An embodiment of the ground source heat exchanger installation structure of the present application is shown, which comprises a ground heat exchanger 10, a horizontal connecting pipe 20 and a cantilever beam support 30. The ground heat exchanger 10 is arranged outside the building body b. The horizontal connecting pipe 20 is connected with the ground heat exchanger 10 and extends horizontally from the outside of the building body b. The cantilever beam support 30 is installed horizontally outside the building body b and is used to support the horizontal connecting pipe 20.

[0025] When the horizontal connecting pipe 20 connected with the ground heat exchanger 10 is arranged to extend horizontally outside the building body b, even if the outside of the building body b still needs to be constructed, for example, pit backfilling, etc., the horizontal connecting pipe 20 is not easily bent and damaged by the stress of the pit backfilling due to the support of the cantilever beam support 30 on the lower side of the horizontal connecting pipe 20. The horizontal connecting pipe 20 is effectively protected, the risk of gas collection after the horizontal connecting pipe 20 is connected upside down is reduced, and the stable and efficient operation of the ground source heat exchanger system is ensured. In addition, the technical solution of the present application can also effectively avoid the situation that part of the ground heat exchanger 10 is cancelled because the horizontal pipe cannot be connected to the building.

[0026] It should be noted that the ground heat exchanger 10 arranged outside the building body b includes the outside in the horizontal direction of the building body b, and also includes the outside in the vertical direction of the building body b, that is, the ground heat exchanger 10 can also be arranged below the building body b.

[0027] As shown in Figure 1 , as a preferred embodiment, the ground source heat exchanger installation structure further comprises a flexible paving layer 40, which is paved on the top of the cantilever beam support 30 and used to contact with the horizontal connecting pipe 20. On the one hand, the flexible paving layer 40 has a larger contact area with the horizontal connecting pipe 20, which can more effectively support the cantilever beam support 30; on the other hand, the flexible paving layer 40 can also effectively absorb some stress received by the horizontal connecting pipe 20. Preferably, in the technical solution of the present embodiment, the flexible paving layer 40 is a fine sand layer. As other optional embodiments, the flexible paving layer 40 can also be an elastic rubber or plastic paving layer.

[0028] As shown in Figure 1 , in the technical solution of the present embodiment, the ground source heat exchanger installation structure further comprises a horizontal wall-penetrating pipe 60, which is connected with the horizontal connecting pipe 20. The horizontal wall-penetrating pipe 60 penetrates from the outside of the building body b to the inside of the building body b. After the horizontal wall-penetrating pipe 60 penetrates to the inside of the building body b, it can be connected with the vertical pipe or other direction pipes and equipment.

[0029] More preferably, in the technical solution of this embodiment, the ground source heat exchanger mounting structure further includes a sleeve 50, which is installed on the building body B. The horizontal through-wall pipe 60 passes through the interior of the sleeve 50 and the horizontal connecting pipe of the building body B. The sleeve 50 can protect the horizontal connecting pipe 20 and prevent the horizontal through-wall pipe 60 from being scratched by the building body B.

[0030] like Figure 1 As shown, in the technical solution of this embodiment, the horizontal wall-penetrating pipe 60 is perpendicular to the horizontal connecting pipe 20. As another optional embodiment, it is also feasible to design the horizontal wall-penetrating pipe 60 and the horizontal connecting pipe 20 at an angle.

[0031] In the technical solution of this embodiment, the horizontal wall-penetrating pipe 60 is also connected to the horizontal connecting pipe 20 via a vertical pipe, which is conducive to achieving pipeline jump. As an embodiment not shown in the figure, the horizontal wall-penetrating pipe 60 can also be directly connected to the horizontal connecting pipe 20.

[0032] Optionally, in the technical solution of this embodiment, if Figure 1 As shown, the horizontal connecting pipe 20 includes a horizontal output pipe 21 and a horizontal return pipe 22, which are respectively connected to the underground heat exchanger 10. It should be noted that the width and length dimensions of the cantilever support member 30 should be reasonably designed based on the number and distribution width of the horizontal output pipes 21 and the horizontal return pipes 22.

[0033] In the technical solution of this embodiment, the ground heat exchanger 10 is arranged in a vertical direction. As other optional embodiments, the ground heat exchanger 10 can also be arranged horizontally or inclined according to design requirements.

[0034] The present invention also provides a method for installing a ground source heat exchanger, the method comprising:

[0035] S10: Installing the underground heat exchanger 10 outside the building b;

[0036] S20: Connect the horizontal connecting pipe 20 to the underground heat exchanger 10, and extend the horizontal connecting pipe 20 horizontally from the outside of the building b;

[0037] S30: A cantilever beam support 30 is set on the outside of the building body b, and the cantilever beam support 30 is supported below the horizontal connecting pipe 20.

[0038] The application of the installation method of the ground source heat exchanger, when the horizontal connecting pipe 20 connected with the ground buried pipe heat exchanger 10 is arranged along the outer side of the building body b, even if the outer side of the building body b still needs to continue construction, such as foundation pit backfilling and the like, since the cantilever beam support 30 supports the lower side of the horizontal connecting pipe 20, the horizontal connecting pipe 20 is not easily bent and damaged by the soil and stone stress of the foundation pit backfilling, the horizontal connecting pipe 20 is effectively protected, the risk of gas collection after the horizontal connecting pipe 20 is connected in an up-down bending manner is reduced, and the stable and efficient operation of the ground source heat exchanger system is ensured. In addition, the technical scheme of the application can also effectively avoid the situation that part of the ground buried pipe heat exchanger 10 is cancelled due to the fact that the horizontal pipe cannot be connected to the building body.

[0039] Preferably, in S30, the flexible layer 40 is laid on the cantilever beam support 30, and the flexible layer 40 is in contact with the horizontal connecting pipe 20. On the one hand, the flexible layer 40 has a larger contact area with the horizontal connecting pipe 20, and can more effectively support the cantilever beam support 30; on the other hand, the flexible layer 40 can also effectively absorb some stress received by the horizontal connecting pipe 20. One way to lay the flexible layer 40 is to lay a fine sand layer on the cantilever beam support 30, and another way to lay the flexible layer 40 is to lay an elastic rubber or plastic layer on the cantilever beam support 30.

[0040] Preferably, in S20, the method further comprises: threading the sleeve member 50 on the building body b, arranging the horizontal wall pipe 60 to be connected with the horizontal connecting pipe 20, and allowing the horizontal wall pipe 60 to pass through the sleeve member 50 from the outer side of the building body b to the inner side of the building body b to be connected with the horizontal connecting pipe, so as to protect the horizontal connecting pipe 20 and avoid the horizontal connecting pipe 20 being scratched by the building body b.

[0041] In S30, the size of the cantilever beam support 30 is set according to the required support area of the horizontal connecting pipe 20, so that the cantilever beam support 30 can effectively support the horizontal connecting pipe 20.

[0042] It should be noted that in the technical scheme of the application, the horizontal direction and the vertical direction not only include the mathematical sense of horizontal and vertical, but also include some angle deviation from the horizontal direction or the vertical direction caused by construction factors.

[0043] It should be noted that the technical scheme of the application is especially suitable for the installation of the ground source heat exchanger of the underground building staggered structure, can solve the problems that the horizontal connecting pipe 20 is easy to collect gas or is easy to be damaged in the secondary construction process, enters the inner side of the building body b at a suitable position, reduces the risk of conflict with the inner side functional division of the building body b, and improves the feasibility of the implementation of the ground buried heat exchanger at different foundation pit elevations.

[0044] From the above description, it can be seen that the technical scheme of the present application can avoid the horizontal connecting pipe 20 being easily damaged due to the involvement of the split-level structure of the underground building, so that the split-level structure of the underground building can use the ground source heat exchanger, the stability of the ground source heat exchanger installation is ensured, the use range of the ground source heat exchanger is increased, and the utilization of renewable energy in construction projects is increased.

Thus, other examples of the illustrative embodiments can have different values. It is to be noted that like numbers and letters refer to like elements throughout the several views of the drawings, and that the use of or insertion of a reference number in one drawing does not preclude its use in another drawing.

The terms "first", "second", "third", etc. can be used herein to describe various elements, but do not imply a particular order or order of use, unless otherwise specified.
