日本开发了一种面向集体住宅的自然能源利用系统。该系统是安装在建筑物的外壁,用太阳能电池和调光玻璃吸收自然能源,以电、热、光的形态送人室内,担负取暖、供应热水、照明、干燥等任务。汇集自然能源的“多功能外装材料”由安装在南侧的日光室和外凸的窗户组成;透明的太阳能电池和调光玻璃是整体式装置;发电与冬季的集热、储热,夏季的通风、排热是高效的,日光室的双层玻璃之间装有电动窗 Japan has developed a natural energy utilization system for collective housing. The system is installed on the outer wall of a building and uses solar cells and light-adjusting glass to absorb natural energy and send it to people in the form of electricity, heat and light. It is responsible for tasks such as heating, hot water supply, lighting and drying. The “multi-functional exterior material” that assembles natural energy consists of a sun room and a convex window installed on the south side; transparent solar cells and dimming glass are integrated devices; electricity generation and winter heat collection and storage, summer Ventilation and heat removal are efficient, and power windows are installed between the double glazed windows of the sunroom
