Technical Field

According to different forms of geothermal energy exchange systems, the ground source heat pump system is divided into a buried pipe ground source heat pump system, a ground water ground source heat pump system and a surface water ground source heat pump system.

In practical application, the ground source heat pump heating system mainly comprises three parts: the system comprises an outdoor ground source heat exchange system, a ground source heat pump host system and an indoor tail end system. Wherein, the outdoor heat exchange system needs to be buried underground.

In the actual construction process, the connection mode and the wall penetrating mode of the horizontal pipes of the outdoor ground source heat exchange system may have great difference, and when a project designer arranges the horizontal pipes of the outdoor heat exchange system according to the building structure condition, part of the horizontal pipes cannot be upturned nearby to be connected into the building due to various reasons such as civil air defense zoning, inconsistent elevation, positions of cold and heat source machine rooms and the like in the building, so that the risk of turning over and gas collection of the horizontal pipes can be caused due to construction such as foundation pit backfilling in the construction process. In order to reduce the risk, many existing methods are to abandon part of heat exchange holes which may affect the horizontal pipe, so that the heat exchange capacity of the ground source heat pump outdoor heat exchange system is reduced, and the occupation ratio of renewable energy sources in project cold and heat source supply is reduced.

On one hand, the contact area of the flexible laying layer 40 and the horizontal connecting pipe 20 is larger, so that the cantilever beam support 30 can be supported more effectively; on the other hand, the flexible layup 40 may also be effective in absorbing some of the stress effects received by the horizontal connecting tubes 20. Preferably, in the technical solution of the present embodiment, the flexible laying layer 40 is a fine sand layer. As other alternative embodiments, the flexible ply 40 may also be a rubber or plastic ply having elastomeric properties.

The sleeve member 50 may play a role of protecting the horizontal connection pipe 20 to prevent the horizontal connection pipe of the horizontal penetration pipe 60 from being scratched by the building body b.

As shown in fig. 1, in the solution of the present embodiment, the horizontal through-wall pipe 60 is perpendicular to the horizontal connecting pipe 20. As other alternative embodiments, it is also possible to design the horizontal through-wall pipe 60 at an angle to the horizontal connecting pipe 20.

It should be noted that, in the technical solution of the present invention, the horizontal direction and the vertical direction not only include the horizontal direction and the vertical direction in the mathematical sense, but also include some angular deviations from the horizontal direction or the vertical direction due to construction factors.

It should be noted that the technical scheme of the invention is particularly suitable for installing ground source heat exchangers of underground building staggered floor structures, 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, and the like, enters the inner side of the building body b at a proper position, reduces the risk of conflict with the inner functional subarea of the building body b, and improves the feasibility of implementing the buried heat exchangers at different foundation pit elevations.
