Background
Geothermal energy is natural heat extracted from the earth's crust, from lava rock inside the earth, in the form of heat, which is extracted directly from the heat sources in the simplest and most cost-effective way. The average ground temperature gradient of China is about 3 ℃/100 meters. I.e. the ground temperature increases about 3 ℃ for every 100 meters downwards increase under the constant temperature layer. 1000-4000 meters underground, and the ground temperature is about 50-135 ℃. The temperature of the intermediate-deep geothermal resources is not enough to be developed and used for generating electricity, but can be a stable heat source for supplying heat to buildings. At present, the geothermal heat exchanger can obtain heat energy under the condition of not pumping underground water, but the construction cost of the geothermal heat exchanger is higher, and the geothermal heat exchanger is positioned in an underground deep layer, so that the installation and the maintenance are inconvenient, the operation cost is increased, and the popularization and the use of the technology are restricted.
