Advantages of Ground source heat pump
(1) ground source heat pump is a renewable energy utilization technology
Ground source heat pump (GSHP) is a heating and air-conditioning system which uses the shallow geothermal resources (usually less than 400 meters deep) on the earth surface as the cold and heat sources for energy conversion. Shallow geothermal resources on the surface can be called geothermal energy, which refers to the low-temperature potential thermal energy stored in the surface soil, groundwater or rivers, lakes that absorb solar energy and geothermal energy. The shallow layer of the earth's surface is a huge solar collector, which collects 47% of the solar energy, more than 500 times of the energy used by human beings every year. It is not limited by region and resources. This kind of renewable energy stored in the shallow layer of the earth's surface is almost infinite, which makes the earth energy become a form of clean renewable energy.
(2) ground source heat pump is an economic and effective energy-saving technology
The temperature of ground energy or surface shallow geothermal resources is relatively stable throughout the year. It is higher than the ambient air temperature in winter and lower than the ambient air temperature in summer. It is a good heat pump and air conditioning cold source. This temperature characteristic makes the ground source heat pump operation efficiency 40% higher than the traditional air conditioning system, so it needs to save energy and operation cost about 40%. In addition, the constant temperature of the ground energy makes the operation of the heat pump unit more reliable and stable, and also ensures the efficiency and economy of the system.
(3) remarkable environmental benefits of GSHP
Compared with air source heat pump, the pollutant emission of ground source heat pump is reduced by more than 40%, compared with electric heating, it is reduced by more than 70%. If combined with other energy-saving measures, energy conservation and emission reduction will be more obvious.
(4) ground source heat pump can realize multi-purpose of one machine
Widely used ground source heat pump system can be used for heating and air conditioning, and also for domestic hot water. One system can replace the original two sets of devices or systems of boiler and air conditioning; it can be used in hotels, shopping malls, office buildings, schools and other buildings, more suitable for heating and air conditioning of villa houses.
(5) low maintenance cost of ground source heat pump air conditioning system
Ground source heat pump is very durable, its mechanical moving parts are very few, all parts are not buried in the ground or installed indoors, so as to avoid the outdoor bad weather, the underground part can guarantee 50 years, the ground part can guarantee 30 years. Therefore, GSHP is maintenance free air conditioning, saving maintenance costs. In addition, the unit has a long service life of more than 15 years, compact unit, space saving, high degree of automatic control, and can be unattended.
