最近,辽宁省锦州东电新型建材厂与东北电力设计院共同研制开发了一种多边形组合式通风天窗。 该产品的研制成功,结束了几十年来我国工业厂房通风一直采用矩形或下沿式天窗的历史。克服了过去传统天窗通风阻力系数大、钢材耗量高、结构荷载大、在使用过程 Recently, Liaoning Jinzhou Dongdian New Building Materials Factory and Northeast Electric Power Design Institute jointly developed a polygonal combined ventilation skylight. The successful development of this product has ended the history of the use of rectangular or sunroof-style sunroofs in the ventilation of industrial plants in China for decades. Overcome the traditional skylight ventilation resistance coefficient, steel consumption, structural load, in use
