Technical Field

[0002] Geothermal heat pump technology, also known as ground source heat pump (GSHP), is a system that uses ground source energy (including soil, groundwater, surface water, low-temperature geothermal water and tail water) as a cooling source for heat pump cooling in summer and a low-temperature heat source for heating in winter. The development path of this technology began with the principle of heat pump cycle. Based on the second law of thermodynamics, it consumes a small amount of electrical energy to drive the heat pump unit to work, realizing the heat transfer from the low-temperature heat source to the high-temperature heat source. As an important part of the geothermal heat pump system, the geothermal energy exchange system is responsible for transferring the underground low-temperature heat energy to the heat pump unit or receiving heat from the heat pump unit and discharging it underground. With the advancement of technology, geothermal heat pump systems have developed into various types including buried pipe heat exchange systems, groundwater heat exchange systems and surface water heat exchange systems to adapt to different environmental conditions.

[0003] At present, geothermal heat pump technology has been widely used and developed around the world. Geothermal heat pump system plays an important role in the construction and industrial fields with its high efficiency, energy saving, environmental protection, pollution-free and good stability. The energy efficiency ratio of geothermal heat pump system is much higher than that of traditional heating and cooling methods. According to statistics, the energy efficiency ratio can reach 3-5, that is, 1 unit of electricity can generate 3-5 units of heat or cold. In addition, the application scope of geothermal heat pump technology is constantly expanding, from the initial heating and cooling to hot water supply and other fields. In China, the installed capacity of ground source heat pumps has shown a rapid development trend in the past 20 years, with an annual compound growth rate of up to 130%.
