玻璃(li)连栋温室的通(tong)风形式(shi)

玻璃(li)连(lian)栋(dong)(dong)温(wen)(wen)室(shi)(shi)是温(wen)(wen)室(shi)(shi)大棚的(de)(de)(de)一种，主要是以玻璃(li)作为采(cai)光(guang)材料的(de)(de)(de)连(lian)栋(dong)(dong)温(wen)(wen)室(shi)(shi)。玻璃(li)连(lian)栋(dong)(dong)温(wen)(wen)室(shi)(shi)的(de)(de)(de)通(tong)(tong)(tong)风其(qi)主要目的(de)(de)(de)是为了排(pai)除(chu)(chu)温(wen)(wen)室(shi)(shi)内的(de)(de)(de)水(shui)分和温(wen)(wen)室(shi)(shi)内的(de)(de)(de)余热，排(pai)除(chu)(chu)对人体(ti)有害的(de)(de)(de)气体(ti)，还能较(jiao)好的(de)(de)(de)调节温(wen)(wen)室(shi)(shi)内的(de)(de)(de)空气成(cheng)分，使温(wen)(wen)室(shi)(shi)内的(de)(de)(de)空气、湿度已经(jing)环境温(wen)(wen)度等(deng)更(geng)适宜植物的(de)(de)(de)生长。玻璃(li)连(lian)栋(dong)(dong)温(wen)(wen)室(shi)(shi)通(tong)(tong)(tong)风一般通(tong)(tong)(tong)过两(liang)种形式：

1、自(zi)然(ran)通(tong)(tong)风(feng)(feng)(feng)：玻(bo)璃连(lian)栋(dong)温(wen)室大(da)部(bu)分时(shi)(shi)(shi)间依靠自(zi)然(ran)通(tong)(tong)风(feng)(feng)(feng)调(diao)节室内环境。大(da)型生产性玻(bo)璃连(lian)栋(dong)温(wen)室的结构形(xing)式一(yi)般(ban)为双(shuang)坡面(mian)连(lian)栋(dong)温(wen)室，通(tong)(tong)风(feng)(feng)(feng)形(xing)式为在侧墙和(he)屋脊设置通(tong)(tong)风(feng)(feng)(feng)窗(chuang)(chuang)。其(qi)通(tong)(tong)风(feng)(feng)(feng)总面(mian)积不小于温(wen)室地面(mian)积的15%，好大(da)于30%。屋脊风(feng)(feng)(feng)窗(chuang)(chuang)开启时(shi)(shi)(shi)， 窗(chuang)(chuang)扇(shan)好可以超过水平面(mian)向上倾斜(xie)， 全打开时(shi)(shi)(shi)与(yu)(yu)水平面(mian)形(xing)成100角(jiao)，则可获得良好的通(tong)(tong)风(feng)(feng)(feng)效果。自(zi)然(ran)通(tong)(tong)风(feng)(feng)(feng)的通(tong)(tong)风(feng)(feng)(feng)量与(yu)(yu)风(feng)(feng)(feng)速、风(feng)(feng)(feng)向、通(tong)(tong)风(feng)(feng)(feng)窗(chuang)(chuang)位置、通(tong)(tong)风(feng)(feng)(feng)窗(chuang)(chuang)面(mian)积及温(wen)室内外温(wen)度差有关。

2、强(qiang)制通(tong)(tong)风(feng)：玻璃连栋温(wen)(wen)室虽然(ran)大部分(fen)时(shi)间依赖自(zi)然(ran)通(tong)(tong)风(feng)来(lai)调节环境， 但在夏(xia)季气(qi)温(wen)(wen)较高时(shi)，尤其室外温(wen)(wen)度超过33℃以上的(de)炎热(re)天气(qi)， 单(dan)靠自(zi)然(ran)通(tong)(tong)风(feng)难(nan)以满足温(wen)(wen)室降温(wen)(wen)要求时(shi)， 采(cai)用(yong)(yong)强(qiang)制通(tong)(tong)风(feng)并配合其它(ta)措施进行降温(wen)(wen)是(shi)生(sheng)产(chan)中常用(yong)(yong)的(de)手(shou)段。强(qiang)制通(tong)(tong)风(feng)是(shi)采(cai)用(yong)(yong)风(feng)机(ji)将电(dian)能(neng)或(huo)其它(ta)机(ji)械能(neng)转(zhuan)化为(wei)风(feng)能(neng)， 强(qiang)迫空气(qi)流动来(lai)进行温(wen)(wen)室换气(qi)并达到(dao)降温(wen)(wen)效果。
