一、風管加工制作流程
風管是用于空氣輸送和分布的管道系統，它的種類眾多，不同風管的制作工藝流程有所不同，以常用的金屬風管為例，其加工制作工藝流程如下：1、風管尺寸的核定。根據設計要求、圖紙會審紀要，結合現場實測數據繪制風管加工草圖，并標明系統風量、風壓測定孔的位置。2、風管展開。依照風管施工圖（或放樣圖）把風管的表面形狀按實際的大小鋪在板料上；展開方法有三種即平行線展開法、放射線展開法和三角線展開法。3、板材剪切前必須進行下料復核，復核無誤后按劃線形狀進行剪切。4、板材下料后在壓口之前，必須用倒角機或剪刀進行倒角。5、板材的拼接。和圓形風管的閉合咬口可采用單咬口；矩形風管或配件的四角組合可采用轉角咬口、聯合角咬口、按扣式咬角；圓形彎管的組合可采用立咬口。6、畫好折方線，在折方機上折方。制作圓風管時，將咬口兩端拍成圓弧狀放在卷圓機上圈圓。7、折方或卷圓后的鋼板用合縫機或手工進行合縫。操作時，用力均勻，不宜過重。咬口縫結合應緊密，不得有脹裂和半咬口現象。8、風管的加固：風管一般可采用楞筋、立筋、角鋼、扁鋼、加固筋和管內支撐等形式加固。如果您有購買風管的需要，可以先來了解一下風管十大品牌。
二、風管機和中央空調的區別
風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)一(yi)般(ban)指(zhi)風(feng)(feng)管(guan)(guan)(guan)(guan)式(shi)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)機(ji)(ji)(ji)，俗稱風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)，是(shi)(shi)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)聯(lian)接風(feng)(feng)管(guan)(guan)(guan)(guan)向室內送風(feng)(feng)的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)。它和(he)中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)的(de)(de)(de)區別主要(yao)(yao)有：1、安裝成(cheng)本不(bu)同：風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)和(he)中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)達到的(de)(de)(de)制(zhi)(zhi)冷(leng)制(zhi)(zhi)熱(re)效果(guo)都類似，然而風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)安裝成(cheng)本相(xiang)(xiang)對(dui)來(lai)說更(geng)低(di)，所以(yi)擁有更(geng)高的(de)(de)(de)性價比。很多(duo)公司家庭都會選(xuan)擇(ze)(ze)風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)，其銷量也是(shi)(shi)非常不(bu)錯。2、能(neng)耗不(bu)同：由于(yu)中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)普遍采用(yong)(yong)(yong)變頻(pin)(pin)技(ji)術，風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)基本都是(shi)(shi)定頻(pin)(pin)技(ji)術，中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)的(de)(de)(de)能(neng)耗相(xiang)(xiang)對(dui)小(xiao)一(yi)些(xie)，節能(neng)能(neng)力更(geng)強。所以(yi)購(gou)買(mai)(mai)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)時，除了要(yao)(yao)考(kao)慮購(gou)買(mai)(mai)價格外(wai)(wai)，能(neng)耗成(cheng)本我們(men)也是(shi)(shi)需要(yao)(yao)考(kao)慮的(de)(de)(de)。3、舒適度(du)不(bu)同：安裝過風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)的(de)(de)(de)朋友(you)都知道，風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)的(de)(de)(de)噪聲(sheng)還(huan)(huan)是(shi)(shi)不(bu)小(xiao)的(de)(de)(de)。和(he)中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)相(xiang)(xiang)比，風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)帶給人(ren)的(de)(de)(de)舒適度(du)就更(geng)差些(xie)。4、工作(zuo)原理不(bu)同：風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)的(de)(de)(de)和(he)普通的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)一(yi)樣(yang)，一(yi)臺外(wai)(wai)機(ji)(ji)(ji)對(dui)應(ying)一(yi)臺室內機(ji)(ji)(ji)，屬于(yu)單(dan)聯(lian)機(ji)(ji)(ji)；中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)不(bu)一(yi)樣(yang)，一(yi)臺外(wai)(wai)機(ji)(ji)(ji)對(dui)應(ying)多(duo)臺室內機(ji)(ji)(ji)，屬于(yu)多(duo)聯(lian)機(ji)(ji)(ji)，且(qie)每(mei)個房間(jian)(jian)都能(neng)單(dan)獨控制(zhi)(zhi)。在工作(zuo)原理上(shang)，中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)的(de)(de)(de)是(shi)(shi)冷(leng)媒和(he)空(kong)(kong)(kong)(kong)(kong)氣(qi)直接交換，制(zhi)(zhi)冷(leng)效果(guo)很快；風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)是(shi)(shi)以(yi)一(yi)種全(quan)空(kong)(kong)(kong)(kong)(kong)氣(qi)系統來(lai)工作(zuo)，制(zhi)(zhi)冷(leng)速度(du)相(xiang)(xiang)對(dui)慢些(xie)，還(huan)(huan)忽冷(leng)忽熱(re)不(bu)夠(gou)穩定。5、適用(yong)(yong)(yong)范疇不(bu)同：風(feng)(feng)管(guan)(guan)(guan)(guan)機(ji)(ji)(ji)空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)適用(yong)(yong)(yong)于(yu)相(xiang)(xiang)對(dui)較小(xiao)的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)間(jian)(jian)，中(zhong)央空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)適用(yong)(yong)(yong)于(yu)較大(da)的(de)(de)(de)空(kong)(kong)(kong)(kong)(kong)間(jian)(jian)，空(kong)(kong)(kong)(kong)(kong)間(jian)(jian)的(de)(de)(de)大(da)小(xiao)對(dui)于(yu)兩(liang)種空(kong)(kong)(kong)(kong)(kong)調(diao)(diao)(diao)的(de)(de)(de)選(xuan)擇(ze)(ze)有一(yi)定的(de)(de)(de)影響。
