Description

technical field [0001] The invention relates to a ground source heat pump system that balances winter and summer loads and overcomes thermal short circuit, and belongs to the field of energy and air conditioning technology. Background technique [0002] The ground source heat pump system (hereinafter referred to as ground source heat pump) with buried pipe heat exchange is known as the most promising air-conditioning technology in the 21st century, which is characterized by energy saving and environmental protection. Geothermal heat exchangers can be arranged horizontally or vertically. Vertical geothermal heat exchangers have attracted widespread attention due to their advantages of less land occupation and stable performance. According to the different forms of buried pipes, there are generally single U-shaped pipes, double U-shaped pipes, casing type and other forms; according to different buried depths, they are divided into shallow buried (buried depth ≤ 30m), medium bu...

AI Technical Summary

Problems solved by technology

The air conditioning system under these modes is not a pure ground source heat pump, but half ground source heat pump and half solar energy heating, and the energy saving and environmental protection advantages of the ground source heat pump have not been fully utilized

[0007] 2. Thermal short circuit problem of underground vertical pipe heat exchanger

At present, the way to eliminate thermal short circuit in engineering applications is to add a pipe divider between the U-shaped pipes to separate the two pipes as much as possible. The diam...
