YaHei"; font-size: 14px;">一個好的空調系統設計，其排氣系統得要合理，這一點往往被忽視。在民用建筑中，尤其是高層建筑中，圍護結構的氣密性非常好，只有少量的空氣才能維持房間的正壓。約85 ~ 90%的新風量得要通過有組織的排風排到室外，以保證供排風平衡，否則無法將適量的新風送入室內。在民用建筑中，廢氣通常通過衛生間、開水間等輔助房間排到室外。此外，有時應增加排氣系統，以確保供氣和排氣的平衡。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">在變風量空調系統中的應用：在變風量空調系統中，一般在外區采用變風量方式，在內區采用定風量方式。在風量和風壓不斷變化的送風系統中，內部區域的定風量設計離不開定風量閥。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">在潔凈空調系統中的應用：潔凈空調系統中保持潔凈室的正壓值非常重要，通過在排風或供排風系統中增加一個設定風量閥，可以有效保證潔凈室的正壓值。手術進行中和不進行時，手術室的正壓應保持在潔凈的手術室內。作業進行時，新鮮空氣量是保證正壓所需的新鮮空氣量加上人員所需的新鮮空氣量。當運行未進行時，新風量為保證正壓所需的僅有新風量，因此需要在新風管上設置兩位定風量閥。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">風道主要是指中央空調系統的<a href='http://www.142779.com/news/434.html' target='_blank' class='key_tag'><font><strong>通風管道</strong></font></a>，往往被忽視，但卻是空調系統的重要組成部分。風道由薄鋼板、鋁板、硬pvc板、玻璃鋼等復合材料制成，是輸送空氣和空氣混合物的各種管道的總稱。隨著科學技術的發展，建筑機具的種類和型號越來越多。施工機具的配置應根據工程性質、施工條件和設計圖紙的要求合理配置。</span></p><p
