Ground temperature energy heat exchanger and mounting method thereof

Abstract

The invention relates to a ground temperature energy heat exchanger and a mounting method thereof. The heat exchanger comprises an inner tube made of heat insulation materials and an outer tube which is arranged outside the inner tube in a sleeving mode and made of heat conduction materials. An end cap is arranged at the lower end opening position of the outer tube to form closed structural matching, the lower end of the inner tube extends to the lower end of a cavity of the outer tube to form a communicated structure, a medium inlet is formed in the upper end of the outer tube, a medium outlet is formed in the upper end of the inner tube, media are conveyed to the bottom of the tube through the outer tube and are pumped to a ground source heat pump on the ground through the inner tube communicated with the outer tube for heat exchange, and therefore utilization of ground temperature energy is achieved. The heat exchanging efficiency between the outer tube and a stratum can be improved through the outer tube made of the heat conduction materials, and the inner tube made of the heat insulation materials can guarantee the heat preservation effect on the media after heat exchange. The heat exchanger is extremely high in heat exchange efficiency, and the number of ground source wells in a ground source heat pump air conditioning system can be reduced.

Description

technical field [0001] The invention relates to the technical field of geothermal energy application, in particular to a geothermal energy heat exchanger and an installation method thereof. Background technique [0002] As a huge, stable, controllable, clean and environmentally friendly energy, geothermal energy has been applied on a certain scale in some areas of my country at this stage. The development of geothermal energy is mainly through the ground source heat pump air conditioning system for heating and cooling. The principle of the ground source heat pump air conditioning system is to transport the medium to the ground for heat exchange, and extract the heat exchanged medium to the ground source on the ground. The heat pump unit and the ground source heat pump machine exchange heat with the indoor air-conditioning terminal system to realize cooling or heating of the building. [0003] In the existing ground source heat pump air-conditioning system, in order to obtai...
