Embodiment Construction

[0009] specific implementation plan

[0010] A ground source heat pump system generally includes a low-temperature heat source end, a ground source heat pump unit, and a cooling end. Cooling terminal equipment generally includes floor radiant or fan coil units.

[0011] During the heating process, the 7°C low-temperature hot water at the evaporator 5 end of the ground source heat pump unit 11 is discharged through the return water pipe 1 into the hollow pipe 3 of the concrete pipe pile buried deep in the ground, and the low-temperature hot water passes through the hollow pipe 3 of the concrete pipe pile The wall exchanges heat with the ground, and when the temperature rises to 12°C, it is pumped to the evaporator 5 end of the ground source heat pump unit 11 as a low-temperature heat source, thereby realizing the heating of the ground source heat pump system.

[0012] When cooling in summer, the high-temperature hot water at the condenser end of the ground source heat pump uni...

Abstract

A tubular pile type ground source heat pump system is applied to construction heating, comprising a low-temperature heat source end, a ground source heat pump set and a radiating tail end; the system can be used in winter and summer; during heating, low-temperature hot water at an evaporator end of the ground source heat pump set is discharged into a hollow pipe of a concrete tubular pile embedded underground through a pipeline, and then, low-temperature hot water is heat-exchanged with the ground through the tubular pile wall; after heated, the low-temperature hot water is extracted to the evaporator end of the ground source heat pump set to be used as a low-temperature heat source, thereby realizing heating of the ground source heat pump system. The tubular pile type ground source heat pump system is capable of heating in winter while cooling in summer, and can ensure heat balance of underground soil; simultaneously, the system can solve the problems that the groundwater system lacks water and a soil pipe system has large floor area, thereby saving energy and protecting environment.

Description

technical field [0001] The invention relates to a ground source heat pump system, in particular to a low-temperature heat source end of the ground source heat pump system. Background technique [0002] At present, the low-temperature heat source end of the known ground source heat pump system generally adopts an underground water system and a soil buried pipe system. Such a system is highly efficient, energy-saving, and environmentally friendly, and has been vigorously promoted and applied by the country. The groundwater system requires abundant groundwater resources, which cannot be used in water-deficient areas; the soil buried pipe system needs to occupy a large area of ​​open space, which is not suitable for application in high-rise buildings and buildings with small footprints, and its promotion is limited. [0003] In many areas of our country, the geology is loose, and buildings need piling. Prestressed concrete pipe piles are composed of hollow pipes (outer diameter...
