Ground source heat pump (ground source heat pump) is a kind of high efficiency and energy saving air conditioning system, which can make use of the shallow underground geothermal resources, which can both heat and refrigeration. The ground source heat pump can transfer low temperature position heat to high temperature by input a small amount of high grade energy. The ground energy can be used as heat source of heat pump heating and summer air conditioning in winter respectively, that is, in winter, we can take out the heat from the earth's energy and raise the temperature to provide indoor heating. In summer, we can get the indoor heat and release it to the ground energy. The main advantages of the ground source heat pump system are:
1, high efficiency: general air conditioning to air heat transfer called air cooling heat pump, the disadvantage is that the weather is hot or cold most need cold or heat when the efficiency decreases. The ground temperature is basically constant throughout the year at 16 degrees Celsius, which is slightly higher than the average temperature in the region 1 to 2 degrees, which makes the heat pump both at high efficiency in refrigeration or heating conditions.
2, saving energy costs: operation in winter, COP is about 4.2, the input 1KW power, can obtain 4KW heat, summer running, COP up to 5.3 1KW, input power, cooling capacity of 5KW can be obtained, the energy efficiency is 3-4 times of electric heating and heat exchanger does not need to remove; Cream, reduce the frosting and defrosting energy consumption. Energy saving is about 50% than that of conventional air - source air conditioning.
3, environmental protection: there is no burning process in heat supply, avoid exhaust pollution, save the cooling tower for cold, avoid noise and mould pollution.
4, comfortable: because the ground source heat pump for heating and cooling are accomplished through the cold and hot water pipe near the fan, the air conditioning and heating than conventional air conditioning to be more gentle, not easy to catch a cold heat.
5, save the area: eliminating the cooling tower, the boiler and the coal and slag field, saves land resources, resulting in additional economic benefits, and improve the building's external image.
6, safety: no burning equipment, so there is no hidden danger of explosion, fire and poisoning.
7, the life of the unit is long: heat pump unit is heat exchange under good low temperature well water for a long time, which can greatly prolong the life of the unit.
