溫室需要通風系統來調節和控制室內的溫度和濕度，為植物提供適宜的生長環境。通常，溫室通風系統可以分(fen)為(wei)自(zi)然通(tong)風和強(qiang)制通(tong)風兩(liang)種。所(suo)謂(wei)自(zi)然通(tong)風即(ji)通(tong)過(guo)開(kai)啟(qi)溫(wen)室(shi)(shi)的(de)側(ce)窗或(huo)者天窗，利用溫(wen)室(shi)(shi)內(nei)外(wai)(wai)溫(wen)度(du)(du)差異或(huo)者風壓，實(shi)現溫(wen)室(shi)(shi)內(nei)外(wai)(wai)空氣(qi)對(dui)流，降低(di)溫(wen)室(shi)(shi)內(nei)的(de)溫(wen)度(du)(du)、濕度(du)(du)。所(suo)謂(wei)強(qiang)制通(tong)風即(ji)通(tong)過(guo)啟(qi)動風機等迫使(shi)溫(wen)室(shi)(shi)內(nei)外(wai)(wai)空氣(qi)對(dui)流，調節溫(wen)室(shi)(shi)內(nei)的(de)溫(wen)度(du)(du)和濕度(du)(du)。兩(liang)種通(tong)風方式各有(you)特點，適用于(yu)不同的(de)情形。

為了實現自然通風(feng)(feng)，人(ren)們可以在溫(wen)(wen)(wen)(wen)室側墻或(huo)屋頂上(shang)設置窗戶。一般(ban)地，溫(wen)(wen)(wen)(wen)室側窗有利于增(zeng)加溫(wen)(wen)(wen)(wen)室周邊的(de)通風(feng)(feng)，但開(kai)啟(qi)面積(ji)有限(xian)。而溫(wen)(wen)(wen)(wen)室天窗的(de)開(kai)啟(qi)面積(ji)則要大得多，且熱空氣上(shang)行，所(suo)以溫(wen)(wen)(wen)(wen)室天窗能(neng)更有效(xiao)地增(zeng)加整個(ge)溫(wen)(wen)(wen)(wen)室的(de)通風(feng)(feng)能(neng)力，有利于促(cu)進(jin)整個(ge)溫(wen)(wen)(wen)(wen)室均勻降溫(wen)(wen)(wen)(wen)。

隨著單體溫(wen)室面積的(de)不斷擴大，對于提高溫(wen)室通(tong)風能(neng)力，天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)比(bi)側(ce)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)效(xiao)果(guo)(guo)要(yao)好得多(duo)(duo)。借(jie)助(zhu)開(kai)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)系統(tong)(tong)(tong)(tong)(tong)(tong)，溫(wen)室側(ce)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)和天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)可(ke)以(yi)根據需要(yao)開(kai)啟或(huo)(huo)關(guan)閉。溫(wen)室側(ce)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)通(tong)常(chang)為(wei)(wei)連(lian)(lian)(lian)續(xu)(xu)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)，如果(guo)(guo)溫(wen)室覆蓋了(le)玻璃、PC板等(deng)比(bi)較堅硬的(de)材料(liao)，則采用(yong)連(lian)(lian)(lian)續(xu)(xu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)驅動(dong)；如果(guo)(guo)是薄膜(mo)(mo)(mo)等(deng)軟材料(liao)，則可(ke)采用(yong)卷膜(mo)(mo)(mo)開(kai)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)系統(tong)(tong)(tong)(tong)(tong)(tong)。還有一(yi)(yi)(yi)(yi)個(ge)選擇是使用(yong)充氣保利窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)，即通(tong)過氣囊(nang)充氣或(huo)(huo)放氣，實現保利窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)的(de)閉合和開(kai)啟。溫(wen)室天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)可(ke)以(yi)設(she)計成沿溫(wen)室屋(wu)脊連(lian)(lian)(lian)續(xu)(xu)開(kai)啟或(huo)(huo)者斷續(xu)(xu)開(kai)啟。如果(guo)(guo)是連(lian)(lian)(lian)續(xu)(xu)天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)，則用(yong)連(lian)(lian)(lian)續(xu)(xu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)驅動(dong)，每個(ge)天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)使用(yong)一(yi)(yi)(yi)(yi)套連(lian)(lian)(lian)續(xu)(xu)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)。多(duo)(duo)個(ge)連(lian)(lian)(lian)續(xu)(xu)天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)也可(ke)用(yong)分動(dong)式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)同時啟閉，即開(kai)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)軸(zhou)上的(de)扭(niu)矩分配器(qi)(qi)與(yu)渦(wo)輪(lun)(lun)(lun)(lun)蝸桿減(jian)速器(qi)(qi)輸(shu)入軸(zhou)相連(lian)(lian)(lian)，一(yi)(yi)(yi)(yi)個(ge)渦(wo)輪(lun)(lun)(lun)(lun)蝸桿減(jian)速器(qi)(qi)驅動(dong)一(yi)(yi)(yi)(yi)個(ge)天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)。當天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)材料(liao)為(wei)(wei)薄膜(mo)(mo)(mo)時，也可(ke)采用(yong)卷膜(mo)(mo)(mo)開(kai)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)系統(tong)(tong)(tong)(tong)(tong)(tong)；如果(guo)(guo)是斷續(xu)(xu)天(tian)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)，可(ke)從桁(heng)架(jia)式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)、搖(yao)擺(bai)式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)、立柱固定式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)中(zhong)(zhong)任選一(yi)(yi)(yi)(yi)種驅動(dong)系統(tong)(tong)(tong)(tong)(tong)(tong)。其中(zhong)(zhong)桁(heng)架(jia)式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)最為(wei)(wei)常(chang)見，搖(yao)擺(bai)式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)應用(yong)很少，而立柱固定式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)只(zhi)是將桁(heng)架(jia)式(shi)(shi)(shi)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)條(tiao)(tiao)系統(tong)(tong)(tong)(tong)(tong)(tong)中(zhong)(zhong)驅動(dong)軸(zhou)和齒(chi)(chi)(chi)(chi)(chi)(chi)(chi)(chi)輪(lun)(lun)(lun)(lun)移到了(le)溫(wen)室天(tian)溝下面，減(jian)少了(le)開(kai)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)系統(tong)(tong)(tong)(tong)(tong)(tong)對入射光的(de)遮擋，這(zhe)是開(kai)窗(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)(chuang)系統(tong)(tong)(tong)(tong)(tong)(tong)的(de)一(yi)(yi)(yi)

溫(wen)(wen)(wen)室(shi)(shi)(shi)強制通(tong)(tong)風(feng)(feng)系統通(tong)(tong)常(chang)采用低(di)壓大(da)流(liu)(liu)(liu)量(liang)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機或者(zhe)環流(liu)(liu)(liu)風(feng)(feng)扇。低(di)壓大(da)流(liu)(liu)(liu)量(liang)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機主要用來向溫(wen)(wen)(wen)室(shi)(shi)(shi)內(nei)吹風(feng)(feng)，或者(zhe)往(wang)(wang)溫(wen)(wen)(wen)室(shi)(shi)(shi)外抽(chou)風(feng)(feng)。往(wang)(wang)溫(wen)(wen)(wen)室(shi)(shi)(shi)外抽(chou)風(feng)(feng)可以(yi)避免氣流(liu)(liu)(liu)對溫(wen)(wen)(wen)室(shi)(shi)(shi)內(nei)植物的(de)(de)(de)損害，且溫(wen)(wen)(wen)室(shi)(shi)(shi)外空氣將通(tong)(tong)過(guo)溫(wen)(wen)(wen)室(shi)(shi)(shi)各處(chu)縫隙向溫(wen)(wen)(wen)室(shi)(shi)(shi)內(nei)補(bu)充，有(you)(you)利(li)于在溫(wen)(wen)(wen)室(shi)(shi)(shi)內(nei)形成一(yi)個均勻(yun)、風(feng)(feng)速(su)適中的(de)(de)(de)空氣流(liu)(liu)(liu)場(chang)，故應用要廣泛得多。環流(liu)(liu)(liu)風(feng)(feng)扇是一(yi)種較小(xiao)流(liu)(liu)(liu)量(liang)的(de)(de)(de)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機，多用于促進溫(wen)(wen)(wen)室(shi)(shi)(shi)內(nei)空氣的(de)(de)(de)流(liu)(liu)(liu)動，有(you)(you)利(li)于溫(wen)(wen)(wen)室(shi)(shi)(shi)內(nei)溫(wen)(wen)(wen)度、濕(shi)度的(de)(de)(de)均勻(yun)，促進植物葉面(mian)水分(fen)的(de)(de)(de)蒸(zheng)發。當溫(wen)(wen)(wen)室(shi)(shi)(shi)尺寸超出(chu)低(di)壓大(da)流(liu)(liu)(liu)量(liang)軸(zhou)流(liu)(liu)(liu)風(feng)(feng)機的(de)(de)(de)有(you)(you)效(xiao)工作(zuo)距離(li)時，可將環流(liu)(liu)(liu)風(feng)(feng)扇作(zuo)為接(jie)力(li)風(feng)(feng)機使用，以(yi)確保強制通(tong)(tong)風(feng)(feng)的(de)(de)(de)效(xiao)果(guo)。

比較而言，自(zi)然通(tong)(tong)風(feng)(feng)(feng)(feng)耗能少、噪音低，通(tong)(tong)風(feng)(feng)(feng)(feng)均勻，但(dan)通(tong)(tong)風(feng)(feng)(feng)(feng)能力受(shou)溫(wen)室周邊氣(qi)流、溫(wen)室內外溫(wen)差(cha)等因(yin)素影響，波動較大。強制通(tong)(tong)風(feng)(feng)(feng)(feng)要(yao)消耗大量電能，風(feng)(feng)(feng)(feng)機運(yun)行時機械(xie)噪音和風(feng)(feng)(feng)(feng)噪較大，其優點是通(tong)(tong)風(feng)(feng)(feng)(feng)能力較強、通(tong)(tong)風(feng)(feng)(feng)(feng)時間可(ke)(ke)控。因(yin)此，如果溫(wen)室對通(tong)(tong)風(feng)(feng)(feng)(feng)要(yao)求不高，可(ke)(ke)考(kao)慮采用自(zi)然通(tong)(tong)風(feng)(feng)(feng)(feng)。反之(zhi)，應采用強制通(tong)(tong)風(feng)(feng)(feng)(feng)。
