In 1950s, Europe brought in the first high tide of researching ground source heat pump, however, the price of energy is low, and so this system is not economical one and results in no promoting. People didn’t pay attention to this technology until the fist energy crisis. A large number of enterprises began to research, produce and package split heat pump. In this time, Europe had established level buried pipe soil source heat pump, which is usually used to supply heating. Although Europe is the most advanced area in developing ground source heat pump, it had also experience a long way for the experts didn’t know the technology to install, and the workers were not familiar with the principle of heat pump. With the development of science and technology, the law is stricter in formulating energy consumption and environmental pollution, and the ground source welcomes its new development. And some governments offer some subsidy and protection policy to broaden the use range of ground source heat system.
The advantages of ground source heat pump
1.Energy-efficient and stable
The temperature of geothermal energy or shallow ground’s heat source is relatively stable, and the temperature difference between soil and air is 17 degree and it is a good heat source of heat pump and cold source of air conditioner. This character makes the ground source heat pump is more effective than traditional air conditioner. In addition, it will reduce the emission of pollutant.
2.One machine can be used in many ways.heat pump for pool can supply heating, refrigeration and supply domestic hot-water. One system can take place of the original two sets of system: boiler and air conditioner.
3.Movement components in the process of ground source heat pump operation are much less than those in normal systems and it is installed in the room which results in reducing damaging and erosion.
4.The material of ground source heat pump is polyethylene plastic pipe, and its working life can reach 50 years.
Future development of ground source heat pump
The energy of ground source heat pump system comes from natural energy. It will discharge no waste gas, waste water or waste residue, and can be called as green air conditioner. It is considered to be the most effective heating and cold supply system which is friendly to environment, and can be used in any area, no matter in severe cold area or tropical area. It can be widely used in office building, hotel, school, hospital, restaurant, villa and houses.
