1、排煙天窗特點(diǎn)

◎ 重量輕、外形美觀、安裝方便、無(wú)振動(dòng)、成本低、效果好，是一種經(jīng)濟(jì)有效的通風(fēng)方式。
◎ 運(yùn)行無(wú)能耗、無(wú)噪聲、不占室內(nèi)空間。
◎ 設(shè)備容量大，通風(fēng)散熱快,排風(fēng)效率與普通天窗和氣樓比較,流量系數(shù)可從0.6~0.65提高到0.8~0.85，使天窗和氣樓的排風(fēng)效率提高30%。
◎ 骨架選用空腹方鋼管，可確保其剛度、強(qiáng)度、構(gòu)造、制造和安裝符合風(fēng)載荷、雪載荷和抗震的要求，設(shè)備安全、可靠、可連續(xù)運(yùn)行。
◎ 擋雨板采用采光板制成，采光面積大，室內(nèi)光線(xiàn)良好。
◎ 天窗內(nèi)部結(jié)構(gòu)布局合理，空氣流動(dòng)暢通，無(wú)明顯的通風(fēng)死角區(qū)域，流通面積大，容量高，具有可靠的防雨、防雪性能。

◎Light weight,beautiful appearance,convenient installation,no vibration,low cost,good effect,is a kind of economic and effective ventilation mode.
◎Operation without energy consumption,no noise,no occupation of indoor space.
◎The equipment capacity,ventilation,exhaust efficiency and ordinary skylights and clerestory, flow coefficient can be increased from 0.6~0.65 to 0.8~0.85,the skylights and clerestory exhaust efficiency is increased by 30%.
◎The fasting skeleton of square steel tube,can ensure the stiffness,strength,structure,manufacture and installation of wind load,snow load and meets the seismic requirements,equipment safety,reliable,continuous operation.
◎The rain shield plate is made of lighting plate,large lighting area,indoor light is good.
◎The inside of the roof structure reasonable layout,air flow,no ventilation dead area,circulation area, high capacity,has reliable rain,snow properties.
