Ground source heat pump (GSHP) is a kind of device which transfers the low-grade heat energy to the high-grade heat energy by inputting a small amount of high-grade energy (such as electric energy). Generally, ground source heat pump consumes 1kwh of energy, and users can get more than 4.4kwh of heat or cooling capacity.
Ground source heat pump (GSHP) is a heating and air conditioning system, which is composed of water source heat pump unit, geothermal energy exchange system and building internal system. According to the different forms of geothermal energy exchange system, ground source heat pump system can be divided into ground pipe ground source heat pump system, ground water ground source heat pump system and surface water ground source heat pump system.
The concept of "ground source heat pump" was first proposed by Swiss experts in 1912, and the technology was proposed in Britain and the United States. The Nordic countries mainly focus on heating in winter, while the United States focuses on combined supply in winter and summer. As the climate conditions in the United States are very similar to those in China, it is of great significance to study the application of GSHP in the United States for reference to the development of GSHP in China, while the technology of GSHP in China started later than that in Europe and the United States. After the founding of new China, the climax of industrial construction came, and heat pump technology began to be introduced into China. With the energy shortage in the world and the strengthening of energy conservation and emission reduction awareness, the energy-saving advantages of ground source heat pump begin to appear.
In the next few years, China holds the attitude of energy conservation and environmental protection and sustainable development, and if the economy wants to maintain high-speed growth and the energy utilization rate wants to improve, it will encourage the promotion of various energy conservation and environmental protection equipment technology, so the market development potential of GSHP in the future is immeasurable.
