Description

Efficient ground source heat pump heat exchange device

technical field

The utility model relates to a heat exchange device, in particular to a ground source heat pump heat exchange device.

Background technique

Ground source heat pump is a high-efficiency energy-saving system that uses shallow geothermal energy for both heating and cooling. By inputting a small amount of high-grade energy (such as electric energy or fuel heat energy), it realizes the transfer from low-grade heat energy to high-grade heat energy. It is mainly used in air conditioning systems as a heat source for heat pump heating in winter and as a cold source for cooling in summer. To realize this process, the buried heat exchange tubes of ground source heat pumps are buried underground to exchange heat with soil and surface water. At present, the underground pipelines used are mainly U-shaped pipes connected in series or in parallel. U-shaped pipes have less contact surface with the soil, and some schemes use spiral pipelines underground. This way the heat exchange effect will be better. However, in the process of landfilling, due to the structure of the spiral pipeline, it is difficult to apply sufficient force to the middle area of the spiral pipeline during the rammed earth operation, and the soil in contact with some areas of the spiral pipeline is in a loose state, so the loose contact will lead to spiral The pipe cannot effectively absorb formation energy. Therefore, improving the underground pipeline structure will help to improve the heat exchange effect of the ground source heat pump heat exchange device.
