The construction industry to promote ground-source heat pump technology can effectively save energy

Reporters from the end of Shenyang in the first session of the China Ground Source Heat Pump Technology Application and Development Forum, experts at the meeting pointed out that the application of ground source heat pump technology has become a hot topic of building energy conservation, will be vigorously promoted in the construction industry.

Ground-source heat pump technology is an energy-saving and environmental protection technology that has emerged as the global energy crisis and environmental issues are highlighted. Ground-source heat pump is based on surface energy (including soil, groundwater and water) Surface water, etc.) as a heat source, a heat pump air conditioning system that transfers low-grade heat energy to high-grade heat transfer by inputting a small amount of high-grade energy such as electric energy. Ground source heat pump heating in winter, the surface heat "take" out, supply indoor heating, while storing underground cold, to prepare for summer; summer use of air conditioning, the indoor heat "take" out to the surface In the underground storage of heat for winter use. So ground source heat pump is a renewable energy technology.

According to reports, compared with the traditional air conditioning and heating systems, ground source heat pump has many advantages such as renewable use, low operating costs, small footprint, water conservation, environmental protection, high degree of automation, safety and reliability.

It is understood that our country from the 80s of last century to carry out research in this area, in recent years, this technology has become a hot topic in the study of building energy efficiency, and began to be widely used in engineering practice. Since 1996, 20 million square meters of ground source heat pump application projects have been completed in Beijing, Liaoning, Shandong and Hebei.

It is estimated that each promotion of 10 million square meters of ground-source heat pump technology, can save 560,000 tons of standard coal, emission reduction 7.5 billion cubic meters of flue gas emission reduction particulate matter 25,000 tons, 13,400 tons of sulfur dioxide emissions , While also reducing the amount of coal stored per year heating, greatly ease the transport pressure.
