Application of Ground Source Heat Pump Technology in New Building

The use of heat pump technology, "extraction" groundwater input load of solar buildings or to heat buildings in the "transfer" to the ground, to achieve winter heating, summer cooling ...... Chinese Academy of Sciences Guangzhou Institute of Energy scientists have developed a high-temperature ground-source The success of the heat pump has been applied to a building of more than 10,000 square meters, marking that this "national science and technology team" of the Chinese Academy of Sciences has also joined the emerging ground-source heat pump industry. In recent years, ground source heat pump (or water source heat pump) (different from the air heat pump water heater , air source heat pump water heater and solar heat pump water heater ) technology and industry gradually rise in our country, but the current heat pump unit can only output 50 degrees Celsius hot water heating, heating equipment terminal only with fan coil heat, the majority of users use radiator heating difficult to apply.

Under the support of Chinese Academy of Sciences and Ministry of Science and Technology, Chinese Academy of Sciences Guangzhou Energy has developed many high-temperature ground-source heat pumps (different from air-to-heat pump water heaters , air source heat pump water heaters and solar heat pump water heaters ) , You can directly connect the heating radiator, or by the heat exchanger to provide 60 degrees Celsius domestic hot water.

It is understood that this set of equipment has been successfully run in the Chinese Academy of Sciences foreign experts apartment for more than two months. In order to make the building "know what it is," the building area of ​​10,000 square meters originally used only three sets of heating and cooling equipment: the heating network heating, central air-conditioning unit cooling, oil-fired boiler throughout the year to supply domestic hot water, not only investment Large, large footprint, high operating costs, and fuel pollution of the environment. Now, ground source heat pump system to replace the original three sets of systems, but also save 70% of the original energy, heating costs are also saved by half.

Xing Keqiang, Assistant Director of the Bureau of Agency Services of the Chinese Academy of Sciences, said the Chinese Academy of Sciences plans to further promote this technology. The CAS Graduate School of Chinese Medicine at Yuquan Road will adopt this technology on several buildings.
