In the new Zhejiang network June 5 yesterday, the reporter learned from Ningbo Wo Fu Sheng Long Central Air Conditioning Co., Ltd., the company for the 2008 Olympic Games Qingdao International Sailing Media Center developed "ground source / sea water source heat pump central air conditioning" system successfully completed the commissioning , Save energy up to 50%, and no combustion, no waste, no pollution. This is the first time in the history of the Olympic Games that "seawater air conditioners" are adopted, and it is also the first of its kind in public buildings that have been completed in the country. It has become a major highlight of the "Green Olympics." "Sea water air conditioning" energy saving up to 50% "sea water can also become the energy source for air conditioning?" This thing sounds a bit overhang. In response, Ningbo Volkswagen Shenglong company general manager 嵇 Cheng-feng's surprise response, "In fact, the principle of seawater air-conditioning is very simple." "Sea air conditioning" is the scientific name of "ground source / sea water source heat pump central air conditioning system," and its working principle Yes: The soil, seawater and groundwater temperature below 2 to 3 meters above ground are basically maintained at 13 ℃ to 19 ℃, while the superficial layer of the earth is a huge solar collector that collects 47% of the solar energy. Ground source / sea water source heat pump Central air-conditioning is a special pipeline buried underground or surface water, etc., through the heat exchange with the underground soil, etc., to indoor comfortable temperature environment. It is understood that the ground source / sea water source heat pump central air conditioning is very environmentally friendly and energy saving, because of its soil, water as a source of energy, only 50% of the energy consumption can be achieved to provide the same energy; under the same conditions, it is more common than lithium bromide central Air-conditioning technology, energy-saving up to 70%; in the system operation, as the use of freons, natural gas, gasoline and other refrigerants, no gas, no coal, no pollutants, will not cause secondary pollution of the environment. Source / sea water source heat pump technology originated in the United States, Europe and the United States more widely used in the country are rare. "In fact, the working principle of this technique is to concentrate the solar energy absorbed by the shallow surface to extract the heat or cold energy in the groundwater or seawater, so as to achieve the purpose of heating and cooling." Tung Shing-feng very briefly summarized the " working principle. The city's rich Fu Shenglong company is currently one of the few able to produce this advanced, environmentally friendly, energy-saving air-conditioning business. It is understood that in 2003, the United States Department of Energy's recommendation, the Ningbo Shenglong Group's Emei Shenglong Machinery Co., Ltd. and the United States WFOE (WFI) Energy Air Conditioning Co., Ltd., the two sides invested a total of 25 million US dollars in the city set up Ningbo Wo Fu Sheng Long Central Air Conditioning Co., Ltd., by the United States to provide ground source / sea water source heat pump technology, and guide the production and application. Energy-saving and environment-friendly Olympic Games Olympic Organizing Committee Qingdao Sailing International Media Center is one of the major media centers for the 2008 Olympic Games in China. To build a green Olympics, the center requires that internal air-conditioning facilities be advanced, environmentally friendly, energy-saving and open to the world Bidding. After learning of the news, Ningbo Wo Fu Shenglong Company actively participated in the bidding. According to Ningbo Volkswagen Shenglong central air-conditioning Co., Ltd. General Manager 嵇 into the peak introduction, the Qingdao Olympic Sailing Center of the central air-conditioning equipment, a total of 20 companies bidding for the bid. During the global bidding organized by the Chinese Olympic Committee in the last few months, WFI, a joint technology provider of Ningbo Volvo Shenglong Co., proposed the seawater source heat pump central air-conditioning system project and adopted the discerning expert group Of the numerous inspections and arguments, and finally successfully emerged from more than 20 competitors, won the cost of 570 million yuan of Olympic Sailing Media Center central air-conditioning project. Tender group of air-conditioning experts on the sea water source heat pump air conditioning system project evaluation is: sea water source heat pump air conditioning system can replace the boiler room heating system, there is no burning to avoid smoke pollution, cooling and eliminating the need for cooling towers, to avoid mold pollution ; While its comprehensive operating costs only one-half to two-thirds of the traditional way, is a high-tech energy-saving, low operating costs, environmental protection, easy operation of mature high-tech products. Data show that this group of seawater air-conditioning system construction investment 5.76 million yuan, 1.5 million yuan more than the traditional central air-conditioning system. However, its comprehensive operating costs of 168,000 yuan per year, while the traditional central air-conditioning operating costs of about 285,600 yuan per year, saving about 120,000 yuan per year. "Electricity alone can save more than 6,000 degrees a year and there is no pollution to the entire city, which is very much in line with the concept of a green Olympics," Wang Haitao, a Qingdao government spokesman, told reporters. After the successful bidding, Ningbo Wo Fu Shenglong company also specially inspected the local environment, combined with the venue for a special design. At present, 15 seawater source heat pump units with anti-seawater erosion function and power of 88kW have been installed and commissioned at Qingdao Olympic Sailing Center International Media Center, making "seawater air-conditioners" serve Olympic Games for the first time. Government subsidies to promote the use of "ground source air conditioning," the current application of ground source heat pump construction area of ​​more than 100,000 square meters of ground source / sea water source air conditioning in addition to the Olympic Games affirmed and favored, many of our city also actively try to use this environment , New energy-saving products. Municipal government also introduced policies to promote the use of energy-saving air-conditioning. It is understood that at present our city ground source heat pump construction area has more than 100,000 square meters, "Eleventh Five-Year" period will also be in the new construction project to promote the use of ground source heat pump central air conditioning system. The city has favorable conditions for the use of ground source air conditioners. Many enterprises have actively considered the "energy saving" products and used such energy-saving "ground source / seawater source central air conditioners." So far, Ningbo Yinzhou Bank Building, Yinzhou District Water Conservancy Bureau Building, Agriculture and Forestry Bureau office building, Ningbo Yinzhou Investment and Business Center, Yinzhou District Science and Technology Center Building, Ningbo Kaifeng Electric Company Building, Ningbo Xinda Group Building, Yinzhou IRS Building, etc. Ningbo Volkswagen Shenglong are responsible for the installation and commissioning of the project. Including Yinzhou IRS ground source air-conditioning project in the air-conditioning use area of ​​25,000 square meters, the system commissioning in early January this year, the operation is stable, energy-saving effect is obvious. In addition, Yinzhou District Party School, Ningbo Yinfeng Holiday Villa, also have similar ground source air-conditioning system. The survey shows that the surface of the Earth's surface in Ningbo is maintained at about 18 ℃ for about 15 years. It is very suitable for the use of ground source / sea source heat pump air-conditioning system and will not have any impact on groundwater resources and ecological environment. In fact, the municipal government on the promotion of energy-saving air-conditioning products are also very supportive. The municipal government has promulgated policies and regulations, for the promotion of energy-saving directory in line with the city, the single investment of more than 1 million yuan, reaching more than 20% energy-saving effect of corporate energy-saving projects, according to the actual amount of investment projects to give 8% subsidy; The principle of the maximum subsidies in the current control within 800000 yuan. Since last year, the municipal economic commission has also given government subsidies of 8% of the actual investment (excluding construction costs) to units that use energy-saving ground-source heat pumps. "Spring plumbing duck prophet." Enterprises first felt this positive change. Ningbo Wo Fu Shenglong Luo Yulong, chairman of the board told reporters that this year, the company clearly felt that the energy-saving products are being used environment is improving. Initially, when companies recommend this technology, others can see it well, but a construction project, there will be budget constraints, they would rather buy in the early stages of other technologies than our cheaper central air conditioning, reduce initial purchase costs. The future use of high cost, anyway, no one supervision, will not be included in the budget. Now there are government subsidies, units, businesses in the purchase of central air conditioning, it will give more consideration to the use of energy saving. Energy-saving air-conditioning technology is getting more and more attention and encouragement from the governments all over the country. The "Provisional Measures for the Management of Special Funds for the Development of Renewable Energy" promulgated this year by the Ministry of Finance stipulates that funds will mainly support the promotion of solar energy and geothermal energy in buildings in terms of the development and utilization of buildings for heating, heating and cooling renewable energy. application. Beijing Municipality has also introduced a policy of one-time subsidies for investment in fixed assets in accordance with the construction area approved by the municipal planning commission for the following subsidies: underground (table) water source heat pump 35 yuan / square meter, ground source heat pump and reclaimed water source Heat pump 50 yuan / square meter. Chengdu this year will invest 10 million yuan on the use of ground source heat pump construction subsidies. Advocate the use of clean energy Taking advantage of Qingdao Olympic Sailing Media Center "source / sea water source air conditioning" system debugging successful emboldened, recently, Ningbo Wo Fu Shenglong Company and the Ministry of Construction, National Development and Reform Commission Energy Saving Office and jointly issued a "central air conditioning Declaration of Energy Conservation, "called for central air-conditioning installation and use of units to change the energy supply, the use of renewable clean energy. Chen Huai, director of the Policy Research Center of the Ministry of Construction, Xiu Xiaoping, deputy director of Torch Center of China Ministry of Science and Technology, and Wang Ping, vice chairman of China Real Estate Association, all backed up the principle of "ground source / seawater source air conditioner". Wang Ping, vice president of China Real Estate Association, said that in the United States, one-third of the new construction can use "ground source / sea water source air conditioning," but basically not used in China. He called for the entire real estate industry to raise awareness of energy saving and pay attention to the application of new global energy-saving technologies in the development of new buildings so that more "energy-efficient buildings" will emerge in China. Chen Huai, director of the Policy Research Center of the Ministry of Construction, said only 577 million urban residents could save surprising electricity and reduce pollutant emissions if the developers took environmental protection, energy conservation and centralized energy-saving air-conditioning products into account when designing. Survey shows that Chongqing and Shanghai central air conditioning electricity consumption accounted for 23% of the city's total electricity consumption and 31.1%. In response, the general manager of Ningbo Volkswagen Shenglong 嵇 into the peak that the traditional high energy consumption of central air conditioning is limited to its own technology and product structure constraints, caught in the "energy saving" cycle of the strange; the face of this phenomenon, the most fundamental solution The trick is to change the way energy is fed and use renewable clean energy. Related European and American prevalence of energy-saving air-conditioning source / sea water source heat pump air conditioning technology was first born in the United States. In 1954, Americans invented the world's first ground-source heat pump. However, commercial application of ground-source heat pump technology has been mature for nearly 20 years. At present, the ground source / sea source heat pump air-conditioning system has been widely used in the developed western countries with an annual growth rate of 20% to 30%. At present, the proportion of heat pump technology used in residential buildings built in the United States has reached 40% Installed 50,000 sets, and all kinds of buildings in the United States plans to install an annual installation of 1 million units, will reduce annual greenhouse gas emissions 3 million tons, equivalent to 1.5 million vehicles to reduce pollutant emissions, the annual energy savings of up to One billion U.S. dollars. US President Bush uses ground-source heat pump technology in a Texas country house. The Queensland Buckingham Palace also uses ground-source heat pump technology. Unlike the development of ground-source heat pumps in the United States, Central and Northern Europe such as Sweden, Switzerland, Austria, Germany and other countries mainly use shallow geothermal resources, ground-sourced ground-sourced heat pumps for buried coils, indoor radiant floor heating and living provision Hot water, of which almost 100% Swiss residents.
