<p>廚房排煙工程的排煙系統和送風(fēng)系統在管道和排風(fēng)機組成的設備方面有許多相似之處。然而，在實(shí)際設計概念中，有許多不同的特點(diǎn)：</p><p><br/></p><p>一、在設計餐廳的廚房時(shí)，應首先考慮使用自然通風(fēng)，自然通風(fēng)是改善空氣質(zhì)量非常實(shí)用、有效的方法，正確、恰當地利用自然通風(fēng)可以達到環(huán)境空氣質(zhì)量的實(shí)際效果，降低自然通風(fēng)的能耗。</p><p><br/></p><p>二、用送風(fēng)機填充新風(fēng)系統的方法是將幾臺排煙系統通機相互對應配對，組成動(dòng)態(tài)控制關(guān)系，根據安裝的具體情況和實(shí)際需要，如餐廳廚房的環(huán)境溫度，可以合理地控制排風(fēng)機開(kāi)關(guān)和進(jìn)風(fēng)機，使排風(fēng)系統和新風(fēng)系統保持穩定的平衡，改善環(huán)境，降低耗低。</p><p><br/></p><p>三、由于結構空間有限，新風(fēng)進(jìn)氣系統不能根據煙泵風(fēng)機進(jìn)行調節，如果所需的排風(fēng)量較大，以保證排風(fēng)量的變化，則應選用新風(fēng)系統風(fēng)機的變速風(fēng)機，排風(fēng)系統和餐廳廚房空間的負壓值的設置應保證送風(fēng)系統的風(fēng)量，有助于節能降耗。</p><p><br/></p><p>四、將新風(fēng)系統的總風(fēng)量分化到各車(chē)間，根據分化指標設置散流口，保證與車(chē)間排風(fēng)量的穩定平衡，核算每個(gè)車(chē)間設置散流口數量，并將散流口的風(fēng)功率控制在3-5M范圍內。散流口的風(fēng)力太小就需要增加散流口的數量，如果散流口的風(fēng)力太大，吹得人頭部會(huì )不舒服，管道中的灰塵會(huì )被吹出來(lái)。</p><p><br/></p><p>五、新風(fēng)散流口的間距應均勻，散布在相距排煙罩5～2m的方位，形成新風(fēng)系統的帷幕，使排煙罩圍成一圈，迅速充滿(mǎn)新風(fēng)系統，使廚房的煙熱不能向外擴散，也不能直接吹到廚師頭上。</p><p><br/></p><p>六、中央空調的排風(fēng)量遠低于餐廳廚房排煙系統的排風(fēng)量。因此，中央空調新風(fēng)系統的散流口應遠離排煙罩，否則，空氣將被有效地利用冷卻動(dòng)力和熱量排出。</p><p><br/></p><p>七、小車(chē)間通風(fēng)自然，排風(fēng)量小時(shí)可滿(mǎn)足自通風(fēng)，這樣就不需要安裝新風(fēng)系統了，對于面積大、安裝空間大的車(chē)間，可以認為排風(fēng)系統與新風(fēng)系統設備的找正是合適的。</p><p><br/></p>
