Ground source heat pump technology is a building energy-saving and energy supply technology that is worth promoting. Ground source heat pumps make full use of the earth's energy in both shallow and deep layers of land, including natural energy sources such as soil, groundwater, and surface water, as winter heat sources and summer cold sources. Then, ground source heat pump units supply cooling and heating to buildings. It is a new type of central air conditioning system that utilizes renewable energy sources (energy-saving and environmentally friendly) for both heating and cooling. At present, the widespread promotion and use of buried tube geothermal heat pump technology is considered the best way to fully utilize shallow geothermal energy. However, if geothermal energy is extracted or released without restrictions, it will lead to a thermal imbalance. So, how to make reasonable and effective use of this resource is the direction that every practitioner should work together towards. So, next, we will give a brief introduction to the design of ground source heat pump systems and every step in the construction process.
