Ground heat exchanger used for ground source heat pump air conditioning system

Abstract

The invention provides a ground heat exchanger used for a ground source heat pump air conditioning system. According to structural factors of pipes themselves and interaction factors between the pipes and geothermal resources and through structural improvement and optimization, the heat exchange performance of the ground heat exchanger is enhanced, and the heat exchange efficiency between water flows in the pipes of the ground heat exchanger and the geothermal resources is increased. The ground heat exchanger is used in the ground source heat pump air conditioning system, the service life of the ground heat exchanger can be prolonged, the energy efficiency of the ground source heat pump air conditioning system is increased, energy consumption and the fault rate of the system are lowered, and therefore the problem that an existing ground heat exchanger structure is prone to causing low heat exchange efficiency, high fault rate, low energy efficiency, non-obvious energy-saving benefits and the like of the ground source heat pump air conditioning system is solved.

Description

technical field [0001] The invention relates to the technical field of air conditioning and heating, in particular to a ground-buried pipe heat exchanger used in a ground-source heat pump air-conditioning system. Background technique [0002] With the development of the economy and the improvement of people's living standards, the heating and air conditioning of public buildings and residences has become a common requirement. Coal-fired boilers as traditional heating in China not only have low energy efficiency, but also cause serious pollution to the atmosphere. Therefore, coal-fired boilers are being phased out in some cities, while oil and gas-fired boilers have high operating costs. The ground source heat pump air conditioning system is an alternative way to solve heating and air conditioning that has great advantages both technically and economically. [0003] The ground source heat pump air-conditioning system is a high-efficiency, energy-saving and environmentally-fr...
