With the development of science and technology, heat pump technology is gradually being widely used. A heat pump is a type of heat that can be extracted from a low-temperature heat source for heating, and its heat is much greater than the mechanical energy it consumes. In our country, heat source technology can be divided into three categories. Mainly by the low heat source points. Specifically, we study the classification of heat source technology. China's heat pump technology is divided into three categories: water source heat pump, ground source heat pump, and air source heat pump. Water source heat pump is the use of the Earth's water storage of solar energy resources as a cold, heat, air conditioning technology conversion. As the heating source of winter heat pump and summer air conditioner respectively, the water body takes the heat in buildings into the water and releases it to the water body in summer. Because of the low temperature of the water source, the water can be efficiently taken away to reach the summer The purpose of indoor cooling to buildings; and in winter, is through the water source heat pump units, from the water source, "extract" heat, sent to the building heating. Ground source heat pump is the use of shallow water on the surface of the earth (such as groundwater, rivers and lakes) and the soil source of solar and geothermal energy absorption, and the principle of heat pump, both heating and cooling energy efficient air-conditioning system. In winter, respectively, as a heat pump heat source and the summer cold source of cooling, that is, in winter, the heat in the ground to take out to increase the temperature, the supply of indoor heating; Summer, the indoor heat taken out to release Earth can go. Air source heat pump, also known as air source heat pump water heater. Air source heat pump technology is based on the reverse Carnot cycle principle to establish an energy saving, environmental heating technology. Air source heat pump system through the natural energy (air heat storage) access to low-temperature heat source, the system after high-temperature heat integration into a high-temperature heat source, used to take (warm) or supply hot water, the entire system heat collection efficiency is very high. All three of these heat source technologies utilize low-grade heat in nature, doing work on electricity, and then exporting high-taste heat for human use. At the moment when the country advocates the policy of energy saving and environmental protection, it provides favorable space for the development of heat source technology. The use of industry has also gradually developed.
