1. Introduction to ground source heat pump system
The ground source heat pump system uses the shallow underground geothermal resources, i.e., soil source geothermal heat, as the main cold and heat source, electric energy as auxiliary power, and circulating water as heat exchange medium. In winter, the heat pump absorbs heat from the 18℃ soil to produce 45℃ hot water for floor heating. In summer, the heat pumps discharges heat to the 18℃ soil to produce 7℃ cold water for fan coil cooling, realizing air conditioning refrigeration. At the same time, the heat pump owner can use the waste heat to provide domestic water, thus realizing the integration of floor heating and air conditioning.

3. Advantages of ground source heat pump system
In today's society, environmental pollution and energy crisis have become the top priority threatening human survival. How to solve this problem has become a topic for all mankind. In this context, green buildings with environmental protection and energy saving as the main features and corresponding air conditioning systems have emerged, and the heat pump system is the emerging central air conditioning system that meets these requirements.

★ Renewable energy utilization technology
The surface soil and water bodies are not only a huge solar collector, collecting 47% of solar radiation energy, which is more than 500 times the energy used by humans in a year, but also a huge dynamic energy balance system. The surface soil and water bodies naturally maintain a relative balance between energy reception and dissipation. This makes it possible for ground source heat pumps to utilize the nearly unlimited solar energy or ground energy stored in them. Therefore, ground source heat pumps utilize a clean renewable energy technology.

★ High efficiency and energy saving
The groundwater temperature fluctuates slightly throughout the year and the value is relatively stable. The seasonal performance coefficient of the heat pump unit has the characteristics of a constant temperature heat source heat pump. This temperature characteristic makes the ground source heat pump 40-60% more efficient than traditional air conditioners, and the energy saving effect is obvious.

★ Stable and reliable operation
The groundwater temperature is relatively stable throughout the year, and its fluctuation range is far smaller than the change of air. It is a good cold and heat source for the heat pump unit, making the heat unit more reliable and stable, and also ensuring the efficiency and economy of the system. There are no difficult problems such as air source heat pump and winter defrosting, which overcomes the disadvantages of conventional air conditioning caused by changes in external temperature, such as high power consumption and poor effect.

★ Significant environmental benefits
Geothermal heat pump use electricity, which is a clean energy source in itself, but when generating electricity, it consumes primary energy and causes the emission of pollutants and carbon dioxide greenhouse gases. Therefore, the energy-saving equipment itself has less pollution. A well-designed ground source heat pump unit reduces electricity consumption by more than 40% compared with air source heat pumps and more than 70% compared with electric heating.

★ Automatic operation
Ground source heat pump units have stable working conditions, so a simple system can be designed with fewer components, simple and reliable unit operation, and low maintenance costs; the degree of automatic control is high, and the service life can be up to more than 20 years.

In summary, geothermal heat pump systems stand out as the best choice for home heating and cooling due to their exceptional efficiency, environmental benefits, long-term cost savings, and durability. While the initial investment is higher, the long-term benefits make GHPs a smart, sustainable choice for homeowners.
