通風又稱換氣，是利用機械或自然的方法將足夠的新鮮空氣送入室內空間，同時排出不符合衛生要求的污濁空氣，使室內空氣能夠滿足衛生要求和生產過程的需要。建筑物中完成通風工作的所有設施統稱為通(tong)風設備。通風按范圍可分為整體通風和局部通風。完全通風也被稱為稀釋通風，它使整個空間通風。局部通風是將污染物產生的地方的污染空氣直接收集并排放到外部，或者直接向局部空間提供新鮮空氣。局部通風具有通風效果好、節省風量的優點。
通風(feng)(feng)設備(bei)根據空(kong)(kong)(kong)(kong)氣(qi)流(liu)動的(de)(de)功率分為自(zi)然通風(feng)(feng)和機械(xie)通風(feng)(feng)。通風(feng)(feng)的(de)(de)力(li)量是(shi)由(you)室(shi)(shi)(shi)內(nei)和室(shi)(shi)(shi)外空(kong)(kong)(kong)(kong)氣(qi)之(zhi)間的(de)(de)溫差(cha)引起的(de)(de)“熱壓”和由(you)室(shi)(shi)(shi)外空(kong)(kong)(kong)(kong)氣(qi)的(de)(de)作用引起的(de)(de)“風(feng)(feng)壓”。這(zhe)兩個因素有時(shi)單獨存(cun)在(zai)或同時(shi)存(cun)在(zai)。通風(feng)(feng)設備(bei)是(shi)熱壓自(zi)然通風(feng)(feng)的(de)(de)示意圖(tu)。當室(shi)(shi)(shi)內(nei)空(kong)(kong)(kong)(kong)氣(qi)溫度(du)(tu)高于室(shi)(shi)(shi)外空(kong)(kong)(kong)(kong)氣(qi)溫度(du)(tW)時(shi)，室(shi)(shi)(shi)內(nei)熱空(kong)(kong)(kong)(kong)氣(qi)由(you)于密(mi)(mi)度(du)低而上升(sheng)，并從(cong)上部(bu)窗孔排出。室(shi)(shi)(shi)外溫度(du)較(jiao)(jiao)低、密(mi)(mi)度(du)較(jiao)(jiao)高的(de)(de)空(kong)(kong)(kong)(kong)氣(qi)從(cong)較(jiao)(jiao)低的(de)(de)窗戶(hu)流(liu)入(ru)室(shi)(shi)(shi)內(nei)。室(shi)(shi)(shi)內(nei)空(kong)(kong)(kong)(kong)氣(qi)和室(shi)(shi)(shi)外空(kong)(kong)(kong)(kong)氣(qi)之(zhi)間的(de)(de)溫差(cha)越大(da)(da)(即(ji)密(mi)(mi)度(du)差(cha)越大(da)(da))，上下窗戶(hu)之(zhi)間的(de)(de)高度(du)差(cha)越大(da)(da)，窗戶(hu)面(mian)積越大(da)(da)，通風(feng)(feng)量越大(da)(da)。
風(feng)(feng)的大小和方向不(bu)(bu)斷變(bian)化(hua)(hua)，自(zi)然(ran)通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)的通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)效果(guo)不(bu)(bu)穩定。然(ran)而，自(zi)然(ran)通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)不(bu)(bu)消(xiao)耗(hao)能(neng)源，是(shi)一(yi)(yi)種經(jing)濟的通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)措施。動態通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)是(shi)一(yi)(yi)種基(ji)于橫流原理的全壓(ya)或離心式風(feng)(feng)機，它強制(zhi)交(jiao)換(huan)(huan)(huan)室(shi)內(nei)和室(shi)外空(kong)氣(qi)，同(tong)(tong)時(shi)進行降噪(zao)、空(kong)氣(qi)凈(jing)化(hua)(hua)、氣(qi)體熱交(jiao)換(huan)(huan)(huan)等(deng)。動態通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)適用于酒店、公寓(yu)、別墅、辦公樓、商業建(jian)筑、住(zhu)宅(zhai)建(jian)筑、醫院(yuan)、學校等(deng)。適用窗型：平開窗、推(tui)拉(la)窗、固定窗等(deng)。工廠(chang)的通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)設備具有良(liang)好(hao)的隔音效果(guo)。它能(neng)在(zai)保證室(shi)內(nei)空(kong)氣(qi)交(jiao)換(huan)(huan)(huan)的同(tong)(tong)時(shi)隔絕噪(zao)音，隔音量(liang)可(ke)(ke)達(da)32分貝以上。當不(bu)(bu)需要動力通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)時(shi)，廠(chang)房的通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)設備可(ke)(ke)用于自(zi)然(ran)通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)。進入房間新鮮(xian)空(kong)氣(qi)經(jing)活性炭(tan)過濾網過濾后，經(jing)負氧離子發生(sheng)(sheng)器消(xiao)毒，負氧離子發生(sheng)(sheng)器的濃度3106個/cm3。在(zai)廠(chang)房內(nei)安裝通(tong)(tong)(tong)(tong)(tong)風(feng)(feng)設備時(shi)，無需更換(huan)(huan)(huan)窗戶(hu)，只需降低玻(bo)璃安裝部分的高度即可(ke)(ke)。維(wei)(wei)修(xiu)時(shi)，可(ke)(ke)將擋板從房間中拆下進行維(wei)(wei)修(xiu)或更換(huan)(huan)(huan)零件(jian)，過濾網可(ke)(ke)直接拉(la)出(chu)并在(zai)室(shi)內(nei)清(qing)洗。
機(ji)械(xie)通風(feng)(feng)是以(yi)(yi)風(feng)(feng)機(ji)為動力造成空(kong)氣流(liu)動，機(ji)械(xie)通風(feng)(feng)不(bu)受自然(ran)條件的(de)(de)(de)限制(zhi)，可以(yi)(yi)根據需要進行(xing)送風(feng)(feng)和(he)排(pai)風(feng)(feng)，以(yi)(yi)獲得穩定(ding)的(de)(de)(de)通風(feng)(feng)效(xiao)果(guo)。機(ji)械(xie)通風(feng)(feng)和(he)自然(ran)通風(feng)(feng)常用于某些場合。有些房(fang)間(jian)對(dui)空(kong)氣環境有更(geng)高的(de)(de)(de)要求。環境空(kong)氣不(bu)允(yun)許流(liu)入(如醫院的(de)(de)(de)手(shou)術室(shi)(shi)、實驗大(da)樓的(de)(de)(de)精(jing)密(mi)儀(yi)器室(shi)(shi)等)。)，且這些房(fang)間(jian)的(de)(de)(de)機(ji)械(xie)送風(feng)(feng)量(liang)應大(da)于機(ji)械(xie)排(pai)風(feng)(feng)量(liang)(或(huo)只設置(zhi)機(ji)械(xie)送風(feng)(feng)，全部采(cai)用自然(ran)排(pai)風(feng)(feng))，以(yi)(yi)使室(shi)(shi)內壓力大(da)于大(da)氣壓力。過多的(de)(de)(de)室(shi)(shi)內空(kong)氣將通過門、窗和(he)其他縫隙流(liu)出(chu)。
