Buried pipe combined type segmented synergistic heat exchange device

Abstract

The invention relates to a ground source heat pump, in particular to a buried pipe combined type segmented synergistic heat exchange device. The device comprises an outer pipe, a refrigerant pipe is arranged in the outer pipe, the outer pipe comprises multiple sections of base pipes connected in sequence, a connecting piece is arranged between every two adjacent base pipes, a refrigerant pipe supporting piece is arranged in the outer pipe, a lowering guide device is arranged on the outer wall of the outer pipe, a guide head is arranged at the lower end of the outer pipe, the outer pipe is further connected with a lowering pressure adjusting device, the connecting pieces are arranged between the outer pipe and an inner pipe, connection between every two base pipes is facilitated, the refrigerant pipe supporting piece is arranged so that the stability of connection between the refrigerant pipe and the outer pipe can be high, the lowering guide device is arranged so that stability in the lowering process can be guaranteed, the lowering pressure adjusting device is arranged, before lowering, a base hole is filled with fluid, guiding and supporting are provided in the lowering process, buoyancy generated by the fluid to the outer pipe can be controlled through the lowering pressure adjusting device, then it is guaranteed that lowering is stable through the lowering guide device, the guide head and the lowering pressure adjusting device, and construction is convenient.

Description

technical field [0001] The invention relates to a ground-source heat pump, in particular to a ground-buried pipe combined segmental efficiency heat exchange device. Background technique [0002] Ground source heat pumps and air source heat pumps are commonly used air conditioning system components at this stage, which are energy-saving, safe and environmentally friendly. [0003] The ground source heat pump is a device that transfers low-grade heat energy to high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy, etc.) from shallow terrestrial energy. Usually 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 a system in a building, which uses rock and soil, stratum soil, groundwater or surface water as a low...
