In recent years, with the decreasing resources of petroleum, coal and other resources, as a new type of heat exchange technology, ground source heat pump has a broader prospect of use. Its success makes use of renewable solar energy or ground energy reality. Now what is the ground source heat pump, what are its characteristics? Ground source heat pump First, what is the ground source heat pump Ground source heat pump is a shallow ground energy through the input of a small amount of high grade energy (such as electricity) from low grade heat to high grade heat transfer. Usually source heat pump consumes 1kWh of energy, users can get more than 4.4kWh heat or cold. The concept of "ground source heat pump" was first proposed by Swiss experts in 1912, and the proposal of this technology originated in Britain and the United States. The Nordic countries mainly focus on winter heating, while the United States focuses on the supply of winter and summer. Because the climate conditions in the United States are very similar to those in China, studying the application of floor heating pumps in the United States has implications for the development of ground source heat pumps in China. Second, the characteristics of ground source heat pump 1, renewable energy technology: As the ground source heat pump is the use of the Earth's surface shallow geothermal resources (usually less than 400 meters deep) as a cold source of heat, energy conversion heating and air conditioning systems. Surface shallow geothermal resources can be called geothermal energy, refers to the surface soil, groundwater or rivers, lakes absorb solar energy, geothermal energy and low-lying latent heat. Superficial surface of the earth is not limited by resources, resources and so on. This near-infinite renewable energy stored in the shallow superficial earth makes geotech a clean, renewable form of energy. 2, economic energy: Ground Source Heat Pump is a cost-effective energy-saving technologies. The ground source heat pump COP value reached 4 or more, which means that the energy consumption of 1KWh, users can get more than 4KWh of heat or cold. 3, significant environmental benefits: the operation of the plant without any pollution, can be built in residential areas, there is no burning, no smoke, no waste, no need to piling up fuel waste sites, and not long-distance transport of heat. 4, low maintenance costs: Ground source heat pump mechanical moving parts are very small, all parts are not buried in the ground is installed in the room, thus avoiding the harsh outdoor climate, compact unit, saving space; high degree of automation, no People keep.
