Buried pipe combined segmental efficiency heat exchange device

Abstract

The invention relates to a ground source heat pump, in particular to a buried pipe combined segmental efficiency-enhancing heat exchange device, comprising an outer pipe, a refrigerant pipe is arranged in the outer pipe, the outer pipe comprises a plurality of base pipes connected in sequence, and a A connecting piece, a refrigerant pipe supporting piece is arranged in the outer pipe, a downward guiding device is arranged on the outer wall of the outer pipe, a guiding head is arranged at the lower end of the outer pipe, the outer pipe is also connected with a downward pressure regulating device, and a connecting piece is arranged between the outer pipe and the inner pipe, The connection between the two base pipes is convenient, and the refrigerant pipe support is provided, which can make the connection between the refrigerant pipe and the outer pipe have high stability. The lowering guide device can ensure the stability during the lowering process. Before lowering, the base hole is filled with fluid to provide guidance and support during the lowering process. By lowering the pressure regulating device, the buoyancy generated by the fluid on the outer tube can be controlled, and then the lowering guide device, guide head, and lowering pressure regulating device can be used to ensure the lowering. Stable and convenient for construction.

Description

technical field [0001] The invention relates to a ground source heat pump, in particular to a buried pipe combined segmental efficiency-enhancing heat exchange device. Background technique [0002] Ground source heat pump and air source heat pump are commonly used air-conditioning system components at this stage, which are energy-saving, safe and environmentally friendly. [0003] Ground source heat pump is a device that transfers from low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electricity, etc.) in shallow terrestrial energy. Generally, the ground source heat pump consumes 1kwh of energy, and the user can get more than 4kwh of heat or cold. [0004] The ground source heat pump is a heating central air-conditioning system composed of a water ground source heat pump unit, a geothermal energy exchange system, and an in-building system, using rock and soil mass, stratum soil, groundwater or surface water as the low...

AI Technical Summary

Problems solved by technology

[0005] The ground source heat pump heating and air conditioning system is mainly divided into three parts: the outdoor ground source heat exchange system, the ground source heat pump host system and the indoor terminal system. The existing outdoor ground source heat exchange system mainly includes buried pipes, and the buried pipes include outer pipes. The outer pipe is provided with a refrigerant pipe, and the refrigerant pipe is protected by the outer pipe, which is convenient for installation. During the installation process of the existing underground pipe, due to the unstable connection method, the foundation hole needs to be excavated larger, or through more The correcting parts are used to straighten the outer tube, which is costly and interferes with the investment of phase change materials, which is inconvenient for construction and high construction cost
