绿色高层建筑的集分式太阳能热水系统节能环保效益
|
摘要
随着建筑节能的不断发展和践行绿色发展理念的不断深入,在绿色高层建筑上应用太阳能热水系统已成为推进建筑节能的有效措施,然而一些设计问题影响系统的正常运营和节能环保效益。通过优化设计和测试分析得知:总建筑面积为17 775 m~2的30层绿色高层建筑,楼顶安装220 m~2平板型太阳能集热器,日产热水12 t。在寿命期内可替代标准煤5.3×10~5kg或替代电力3.0×10~6kW·h,减排CO_2、SO_2和粉尘分别为1.3×10~6kg、1.0×10~4kg、5.3×10~3kg,节能和环保效益明显,值得大力推广应用。
With the continuous development of building energy efficiency and deepening concept of green high-rise building,the application of solar water heating system on green high-rise buildings has become imperative to promote energy efficiency of buildings for sustainable development.However,normal designs without considering energy saving and environmental protection,the normal operation and life cannot be benefited.Through the design optimization and test analysis,it was known that for heating12 000 liters of water,17 775 m~2floor area with 30 level green high-rise building and the roof equipped with 220 m~2flat panel solar collector is required.During the life period,it can replace the standard coal5.3×10~5kg or replace the power 3×10~6kW·h,and it also contributes to reduce the emission of CO_2,SO_2and dust about 1.3×10~6kg,1×10~4kg,5.3×10~3kg,respectively.Therefore,the energy saving and environmental protection benefits are profound and hence worth promoting.
