Application Of Renewable Energy Resources In Buildings In Huangshan City

There are many types of renewable energy sources,including solar energy,wind energy,tidal energy,geothermal energy,water power,biomass energy and other non-fossil energy sources.But few of them can be used in buildings,such as solar energy,wind power,water source heat pumps,ground source heat pumps,etc.After studied some of literature on renewable energy,and spent two months on study the application of renewable energy in the buildings of Huangshan city and surrounding counties in the field.Mainly including solar thermal,photovoltaic system,ground source heat pump,river water source heat pump.Involving hospitals,schools,communities,industrial plants and other buildings.This paper summarizes the research results and provides suggestions for the integration of construction and renewable energy in Huangshan city.The research contents of this paper covers the following aspects:1.Based on the building energy efficiency and the construction of renewable energy demonstration cities,the development status of renewable energy and the use of renewable energy on the significance of ecological civilization construction in China are expounded.2.Based on the above theories,combining the resource distribution and utilization conditions of solar and geothermal energy in Huangshan city,introduced the renewable energy utilization project and its application status in Huangshan area.The thermal properties of the ground source heat pump were studied,and the temperature field simulation of the water source heat pump was carried out by using the fluid mechanics software Fluent.It is concluded that the combination of solar energy,ground source heat pump and river water source heat pump is applicable in this area.3.Analyzed the project from the perspective of economic and ecological environment and calculated the conventional energy substitution,carbon dioxide emission reduction,sulfur dioxide emission reduction,dust emission reduction,project cost effect ratio,annual savings,static investment recovery period,etc.The study found that the project routine energy replacement amount of 156.24 tons of standard coal,the project cost benefit is 0.22 yuan /k Wh,the average annual electricity savings of 210 thousand yuan.The integration of solar system and building has obvious effect on energy saving,emission reduction and construction cost reduction.4.The results of the research are summarized and analyzed.It is concluded that the application of renewable energy in Huangshan is higher,and the technology is more complete,so it is suitable for further promotion.Some suggestions on the existing problems in the application of renewable energy buildings in Huangshan City are put forward.
