Multi-well-in-one water source heat exchanging method and geothermal well

Abstract

The invention discloses a multi-well-in-one water-source heat exchanging method and a geothermal well. The ground surface is divided into a ground surface shallow water layer, a watertight layer and a ground surface deep water layer by arranging the geothermal well with a certain depth; the geothermal well is divided into an upper part, a middle part and a lower part under the ground surface; the upper part corresponds to the ground surface shallow water layer; the middle part corresponds to the watertight layer; the lower part corresponds to the ground surface deep water layer; water on the ground surface deep water layer is conveyed into an exchanger by a water sucking pump through a pipe and conveyed into the ground surface shallow water layer by the exchanger; and water on the ground surface shallow water layer is directly drained into the ground surface deep water layer by a water draining pump. The method and the geothermal well have the advantages that: 1, the water pumping and recharge problems are solved by only one geothermal well, and the geothermal well has a reasonable structure, and is convenient to construct and low in cost; 2, valuable water resources are saved; and 3, the flexible construction is ensured, and different numbers of geothermal wells can be arranged according to different ground surface conditions.

Description

technical field [0001] The invention relates to the construction field, in particular to a water source heat energy exchange method and a geothermal well for realizing the method. Background technique [0002] With the continuous development of cities and the continuous improvement of people's living standards, the heating and cooling of buildings is becoming more and more important. The traditional heating and cooling methods not only waste resources, but also bring serious environmental protection problems; the method widely used now is to use Natural laws, environmental protection methods that do not waste resources, such as the use of solar energy, geothermal and other green resources, are more and more widely used. The method of using geothermal resources generally uses the temperature difference between the deep layer and the surface of the earth, uses water as the medium, and supplements it with electric energy to achieve the purpose of heating or cooling. The tradit...

Problems solved by technology

The traditional water source heat exchange method is to set up multiple geothermal wells on the surface, which are used to collect geothermal heat and discharge water respectively. Since this structure requires the construction of multiple geothermal wells, it not only wastes a lot of manpower and material resources, but also takes up valuable urban space.
