| 摘 要： | 目前节能玻璃种类繁多,不同气候区建筑外围护结构透光部分选用的玻璃也有所不同.对于采用被动式太阳能系统的建筑,不可盲目使用节能玻璃作为集热部件.被动式太阳能系统集热部件的关键部件(玻璃及框材)应根据气候条件因地制宜的选用.分析了西安农村地区常用的各种节能玻璃的传热系数、太阳能得热系数等性能指标,得出适宜应用在寒冷地区被动式太阳能建筑集热部件的节能玻璃类型.此种材料可有效地提高太阳能得热和室内热环境的舒适度,减少采暖能耗.

| Abstract: | At present,there are various sorts of the energy-saving glass.The glass shall be selected according to different climate zones for building envelope.The energy-saving glass shall not be blindly used as heating element in the building with passive solar energy.The key components,including glass and frame,shall be selected as heating element according to climate.Various performance indexes of Xi’an rural areas,such as heat transfer coefficient,solar heat gain coefficient(SHGC) and so on,are analyzed.The suitable energy-efficient glass as heating collector for passive solar building in cold area is identified,which can effectively improve the SHGC and indoor thermal comfort,decreasing heating energy. |
