Luoyang City, rich in water resources, in the northern city to develop water-source heat pump air-conditioning has a unique advantage. Today in the country to promote building energy efficiency today -
Recently, the real estate development company in the yuan due to the development of the real estate project in the element of the International Groundwater source heat pump air conditioning system, received the first 980,000 yuan Provincial Department of Finance financial subsidies, which Luoyang City enterprises for the first time to obtain such subsidies .
A private real estate business because of the use of energy-saving technologies advocated by the state and get financial subsidies, resulting in the use of water source heat pump desirable.
Luoyang City, the first water source heat pump projects have been subsidized
"This 980000 yuan is only half of the subsidies we get, another 980000 yuan after the completion of the project acceptance can be allocated." Yang Yuan, general manager of the real estate development company said.
In the Ministry of Finance website, the Ministry of Finance, the Ministry of Construction on the second batch of demonstration projects of renewable energy building applications, the location of the International Plaza, one of them, a demonstration area of ​​24,500 square meters, 80 yuan per square meter subsidy can be obtained .
Huang Xin, chief of the Municipal Science and Technology Education Section, introduced in 2006 that the Ministry of Finance and the Ministry of Construction started to subsidize certain demonstration projects in batches in order to encourage the construction of renewable energy in the country. It is understood that a total of 21 such projects nationwide have received state grants, including seven projects in Henan Province, and Luoyang City has only one such project selected.
Economic and social benefits of double harvest
With the economic development and improvement of people's living standards, heating and cooling of public buildings and residential buildings have become common needs. So, energy-saving heat pump in the end where reflected?
With this problem, the reporter with the plumbing engineer Li Runhong to the yuan International Building project site visit. There are 3 black lines in the living room, dining room, bedroom and bathroom in the working-law model room on the 6th floor. They are water supply pipe, return pipe and condensate water pipe respectively. One fan coil pipe is installed in the living room, dining room and bedroom , Equivalent to the end of the central air conditioning equipment.
Li Runhong introduction, water source heat pump works is the heat emitted to the ground, or absorb heat from the ground, and this is the root cause of its energy-saving.
Because the groundwater is constant temperature, so the cooling heat transfer within the building through the heat pump to groundwater, the use of temperature can reach 17 ℃; heating, the groundwater heat through the heat pump unit transferred to the building, The use of temperature difference can reach 11 ℃, on this basis, supplemented by electric energy, not only make full use of groundwater energy, but also can achieve 100% underground recharge, therefore, water source heat pump in energy saving advantages, it is the ideal air conditioning , Boiler replacement.
Li Runhong said that the use of water source heat pump, winter heating costs per square meter per day up to 0.12 yuan, lower than the central heating (0.16 yuan); summer cooling per square meter per day fee of 0.066 yuan to 0.09 yuan, less than half the use of conventional central air conditioning cost.
According to the geothermal central air-conditioning normal service life of 25 years, compared with the conventional system, the International Building, the annual savings of more than 300,000 yuan; in the life of the equipment, CO2 emissions can be about 23,000 tons, to achieve economic and social Benefit of double harvest.
Water source heat pump with good prospects for use
Environmental protection and sustainable development are the preconditions for the healthy development of our economy.
In respect of residential use of warmth, there is an urgent need to develop alternative alternative heating methods in addition to central heating. Water source heat pump is a new technology that can effectively save energy, reduce air pollution and CO2 emissions.
Huang Xin introduction, Luoyang City, the geological conditions are very advantageous, very suitable for the use of water source heat pump.
According to the geological prospecting data, Luoyang City is located at the western end of Luoyang Basin. It enjoys advantageous geographical environment and rich water resources. It is advantageous for developing water source heat pump projects in northern cities. Flow through the urban areas of Luohe, Yi River, Jian River and? E River, groundwater recharge plays an important role, coupled with the construction of Luohe rubber dam, Luoyang New District landscape canal and artificial lake construction, so that the general underground water level Increased, groundwater recoverable increased substantially in urban areas.
According to Municipal Construction Committee statistics, at present, units such as Luoyang Orthopedic Hospital, Yellow Committee Office Building and Hotel, Zhongqiao Building, Lijing Sunshine Ecological Park and other units have adopted the water source heat pump air conditioner. The city's total development and utilization area is about 300,000 square meters. Good effect.
Huang Xin believes that since Luoyang has such a good natural conditions, the country will also step up its efforts to support energy-saving emission reduction projects. I believe Luoyang City, there will be more water source heat pump utilization projects, government departments should also guide and promote the project encouraged by the country to contribute to the work of energy-saving emission reduction in Luoyang City.
