The use of renewable energy is a green city, an important part of green building. On the afternoon of June 7, "2008 Xiamen Building Energy Efficiency and Ecological Building Development Forum" was held in Xiamen International Convention and Exhibition Center. Lin Shui-Chi, deputy director of the Xiamen Municipal Construction and Administration Bureau, said that the next step would be to vigorously promote the promotion of seawater source heat pumps in Linhai buildings, including the Linhai Hotel. Lin Shuzhi said air source heat pump, ground source heat pump, seawater source heat pump and other technologies can apply for subsidies for the use of renewable energy, housing and urban and rural construction department, the Ministry of Finance has a special fund, Xiamen City Finance also have such a project tilt. Air source heat pump: Xiamen part of the hotel has been used From the architectural point of view, energy saving through thermal insulation system, planning and design to achieve. At the same time, we should encourage the use of renewable energy in buildings. Lin Shuzhi said that for Xiamen, the development of solar energy, wind energy, ground source heat pump, air source heat pump, seawater source heat pump has great advantages. At present, the use of solar energy and wind energy in Xiamen has been quite a few. For the whole of South China, heat pump technology has matured. The so-called heat pump, using the temperature difference. There is a temperature difference there will be energy, Lin branch said that if the temperature is higher than 5 degrees Celsius, is very suitable for the promotion of air-source heat pump, because at 5 ℃ under the conditions, you can collect the air, and then compressed air, the air Extract the heat, the heat can be used for heating systems such as hot water supply. Even in winter, the temperature in Xiamen can basically reach above 5 ℃, therefore, the air source heat pump is very easy to use. "At present, some hotels in our city have used air-source heat pump, which reflects very well." Then air-source heat pump will continue to promote, Lin Shui-Chi said. Water source heat pump: heat transfer in summer, winter extract heat and the same view of the branches also hold the same WFI United States, water source heat pump expert Li Su, June 6 at the forum he published "seawater source heat pump central air conditioning in Xiamen Application prospect "speech. Li Su said that water, earth and rocks on the surface of the earth are a huge collector that collects 47% of the solar thermal energy, which is more than 500 times the energy used annually by mankind and is a renewable energy source. Simply put, water source heat pump air conditioning works: In summer, it will transfer the building's heat to the water, because the water temperature is low, you can efficiently take away the heat; in winter, the energy extracted from the water source, through the use of heat pump principle Air or water as a refrigerant to raise the temperature to the building. Water source heat pump available sources of groundwater, rivers and lakes and oceans. Sea water source heat pump: can save more than 2/3 of energy As seawater source heat pump, it is the seawater applied to the water source heat pump air conditioning. Li Su said that seawater source heat pump central air conditioning for the promotion and application of the environment to meet many conditions, to be able to take close to the seawater, the surrounding seawater temperature should be appropriate. Li Su said that the Xiamen island is surrounded by the sea and all areas are relying on the sea. The coastline is 234 kilometers in length and has rich seawater resources. Many buildings are built according to the sea and take short distances. In addition, the average temperature of winter sea water in Xiamen 14-16 ℃, the average summer water temperature 27-28 ℃, the use of seawater source heat pump conditions are good. Li Su said that for the lack of conventional energy sources such as coal, oil and natural gas, and all energy sources in Xiamen, promoting the application of renewable energy such as shallow ground energy to buildings is one of the most economical and reasonable solutions for building energy use s Choice. In addition to environmental protection, the seawater source air conditioning is water-cooled air conditioning system, and the heat source temperature is more stable throughout the year, its cooling efficiency compared with conventional air conditioning, to about 40% higher, the operating cost is 50% of the ordinary central air conditioning ~ 60%. Compared with the traditional heating methods, seawater source heat pump heating electricity boiler to save more than two-thirds of the energy. It is reported that China's Qingdao, Dalian and other places have been applied seawater source heat pump technology, Xiamen has not been applied. Therefore, deputy director of Xiamen City Construction and Administration Lin Shui-Chi said that the next step Xiamen will vigorously promote the use of sea water source heat pump in Linhai Building, including Linhai Hotel.
