Ground source heat pump technology introduced preferential policies

In order to further promote the application of ground source heat pump technology, the Ministry of Finance and the Ministry of Housing and Urban-Rural Development jointly issued a document to provide capital subsidies for ground source heat pump application projects. At present, there are clear preferential policies for ground source heat pump technology in provinces and cities such as Beijing, Hebei, Shandong, and Shanxi. , Including energy-saving investment projects for the implementation of grants, according to the scale of investment grants, according to the effect of energy-saving incentives. Tianjin, Guangdong, Nanjing, Changsha and other provinces and cities have also set up special funds for energy conservation.

According to the survey, taking Beijing as an example, as a leader in promoting the use of ground source heat pump technology, Beijing provided financial subsidies for the use of ground source heat pump technology projects as early as in 2006. For projects that use ground source heat pumps, they can obtain per square meter. A 50-yuan subsidy to encourage the application and promotion of ground-source heat pumps. At present, the application scale of ground source heat pump in Beijing is close to 40 million square meters. Office buildings, houses, schools, shopping malls, hotels, and hospitals are all major applications for ground-source heat pumps. Many ground-source heat pumps are in the 2008 Olympics and National Grand Theatre. There are different degrees of application.

Ground-source heat pump projects have been operating in recent years, and energy-saving effects have gradually emerged. According to conservative estimates, the annual shallow geothermal energy available in 287 prefecture-level cities in China equals 356 million tons of standard coal, excluding depletion of electricity consumption. It can save an equivalent of 248 million tons of standard coal and reduce carbon dioxide emissions by 652 million tons. It is estimated that by 2015, China’s use of shallow geothermal energy is equivalent to 52.69 million tons of standard coal.

According to experts, ground-source heat pumps differ from general central air-conditioning systems in that they not only need to purchase equipment, materials, and install mainframes and indoor fan coils, but also need to drill wells, consume a lot of manpower, material resources, and financial resources, plus a source-source heat pump. In addition to installing air-conditioning components, it is also necessary to install floor heating and domestic hot water, which results in higher ground-source heat pump costs than general central air-conditioning. The government subsidizes the ground source heat pump to a certain extent, narrowing the difference between ground source heat pump products and other products, which is beneficial to the promotion of ground source heat pump technology.

It is reported that at present, the market share of ground source heat pumps is less than 7%. Local governments, through financial subsidy and other means, award incentives and subsidies for companies using ground source pumps and project funds, which have become the biggest driving force for ground source heat pump products to reach the market. Geothermal pumps have been promoted as energy-saving technologies in provinces and cities such as Beijing, Hebei, and Shandong, and ground-source heat pumps have become known and gradually recognized.
