style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">根據通風管廠家介紹，地下室的通風方式是合理布置排氣管和出風口，發生火災時也可兼作排煙管和排煙口；地下一層考慮由車道自然通風，其他樓層也由平時的送風系統作為火災時的送風系統。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">每個通風設備、排風、排煙、送風系統應設豎井，進風口應設在地面潔凈處。如果能設在離地下主樓一定距離的地方，受火災氣體的影響會小一些。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">系統劃分：排煙系統防煙分區的劃分應結合建筑防火分區考慮，這樣有利于地下室通風系統兼作排煙系統，不會出現排煙管道穿越防火分區的現象。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">另外還可以<a href='http://www.142779.com/news/445.html' target='_blank' class='key_tag'><font><strong>安裝通風管道</strong></font></a>，普通離心風機就可以滿足排風排煙的要求。而大容積離心風機只能安裝在地面，占地面積大，需要很大的機房。高溫軸流風機是消防專用風機，也能滿足280運行30分鐘的要求。但高溫軸流風機體積小，一般可以吊裝。如果機房較小，在實際工程設計中往往采用高溫軸流風機排煙。</span></p><p
