（1）根據脫排（集煙罩）的總投影面積S，以每平方米按2000 m3/h處理風量的計算方法確定訂購油煙凈化器總處理風量?？偺幚盹L量=S×2000。<br /> （2）根據匹配風機選型<br /> a、計管道阻力：管道阻力包括局部阻力（變徑管、彎頭、進出風口產生的阻力）和沿程阻力（各段直管產生的阻力）。<br /> b、風機的全壓=（管道阻力+設備阻力）×100+15%<br /> 根據計算全壓和總處理風量選定風機的型號規格<br /> 注：在選擇風機的全壓和風量時應考慮風機的噪聲比級，在同等參數條件下，選擇噪聲比低的風機，必要時可設置消聲房和消聲管。<br /> 2. 管道的布置及安裝預留空間<br /> （1）廚房內的散熱管道、油煙排放管路必須分別設置。<br /> （2）凈化器安裝應有必要的空間，凈化機的檢修門前留有1~2m長度（視規格而定）的平臺以便凈化器的清洗、維護和保養.<br /> （3）根據風機進出口徑安裝同截面的風管并保證進出口處留有一定長度的直管，方可保證設備凈化效率，其進風口直管長度為1.5D，出風口直管長度為3D（D為當量直徑。D=2AB/（A+B），A、B為矩形管邊長）。</span><br /> </div> </div> </div>
