Method for slowing down heat interference of underground water source heat pump

Abstract

The invention is applicable to the technical field of clean energy equipment, and provides a method for slowing down the heat interference of an underground water source heat pump. The method for slowing down the heat interference of the underground water source heat pump comprises a heat pump unit communicating with a first hoistway through a first pipeline and communicating with a second hoistway through a second pipeline, and a heat barrier well arranged between the first hoistway and the second hoistway and communicating with the first pipeline or the second pipeline, wherein the heat pumpunit, the first hoistway and the second hoistway communicate with liquid driving equipment; the first hoistway, the second hoistway and the heat barrier well are arranged in an aquifer; the heat pumpunit, the first hoistway, the second hoistway, the heat barrier well and the aquifer form water flow circulation; and the heat barrier well and the heat pump unit divide the water pumping flow, and change the pumped and irrigated groundwater flow field to delay the occurrence of the heat interference. The method for slowing down the heat interference of the underground water source heat pump provided by the invention has the advantages of low investment cost, low interference resistance, convenience in adjustment, high energy utilization rate and convenience in small-field popularization andimplementation.

Description

technical field [0001] The invention belongs to the technical field of clean energy equipment, and in particular relates to a method for alleviating heat interference of an underground water source heat pump. Background technique [0002] As a high-efficiency, energy-saving, and environmentally-friendly air-conditioning system, groundwater source heat pumps have been widely used at home and abroad. The combination of heat pump systems and aquifer energy storage technology can improve the operating efficiency of units. Thermal interference is the phenomenon that the cold and heat in the recharge well enters the pumping well, which leads to a gradual decrease in the operating efficiency of the unit. Especially for sites with limited area, the distance between the pumping and irrigation wells is small, and the degree of thermal interference becomes more serious. The current solution to the problem of thermal interference is mainly to introduce auxiliary cold and heat sources an...
