1.橫向式通風。當雞舍長度較短跨度不超過10米(mi)時(shi)，多(duo)采(cai)用(yong)橫(heng)向(xiang)式(shi)通(tong)風(feng)。橫(heng)向(xiang)式(shi)通(tong)風(feng)主(zhu)要(yao)有(you)正(zheng)壓(ya)係(xi)統(tong)和(he)負(fu)壓(ya)係(xi)統(tong)兩(liang)種(zhong)設(she)計(ji)。所(suo)謂(wei)正(zheng)壓(ya)通(tong)風(feng)係(xi)統(tong)是(shi)靠(kao)風(feng)機(ji)將(jiang)外(wai)界(jie)新(xin)鮮(xian)空(kong)氣(qi)吸(xi)入(ru)舍(she)內(nei)，使(shi)舍(she)內(nei)空(kong)氣(qi)因(yin)氣(qi)壓(ya)增(zeng)大(da)又(you)自(zi)行(xing)由(you)排(pai)氣(qi)口(kou)排(pai)出(chu)舍(she)外(wai)的(de)氣(qi)體(ti)交(jiao)換(huan)方(fang)式(shi)，該(gai)係(xi)統(tong)雖(sui)然(ran)可(ke)調(tiao)節(jie)舍(she)內(nei)溫(wen)度(du)，改(gai)善(shan)舍(she)內(nei)空(kong)氣(qi)分(fen)布(bu)狀(zhuang)況(kuang)，減(jian)少(shao)舍(she)內(nei)賊(zei)風(feng)等(deng)，但(dan)因(yin)其(qi)具(ju)有(you)設(she)備(bei)成(cheng)本(ben)高(gao)，費(fei)用(yong)大(da)，安(an)裝(zhuang)難(nan)度(du)大(da)，適(shi)用(yong)範(fan)圍(wei)較(jiao)窄(zhai)等(deng)缺(que)點(dian)，故(gu)在(zai)生(sheng)產(chan)實(shi)踐(jian)中(zhong)，使(shi)用(yong)較(jiao)少(shao)。

2.縱向式通風。當雞舍長度達80米以上，跨度在10miyishangshi，zeyingcaiyongzongxiangshitongfeng，zheyang，jiyouhualejishetongfengshejidehelixing，jiangdileanzhuangchengben，yekehuodejiaolixiangdetongfengxiaoguo。zongxiangshitongfengshizhijiangfengjianzhuangzairoujishedeyiceshanqiangshang，zaifengjideduimianshanqianghuoduimianshanqiangdeliangceqiangbishangshelijinfengkou，shixinxiankongqizaifuyazuoyongxia，chuanjinjishedezongjingpaichushewai。paifengshanchang1.25～1.40米，排風機的扇麵應與牆麵成100度角，可增加10%的通風效率，空氣流速為2.0～2.2米/秒，兩台風機的間距以2.5～3.0米(mi)為(wei)宜(yi)。在(zai)夏(xia)季(ji)高(gao)溫(wen)時(shi)節(jie)，為(wei)使(shi)雞(ji)舍(she)有(you)效(xiao)降(jiang)溫(wen)，通(tong)常(chang)需(xu)在(zai)進(jin)風(feng)口(kou)安(an)裝(zhuang)濕(shi)簾(lian)，即(ji)濕(shi)簾(lian)降(jiang)溫(wen)。有(you)關(guan)通(tong)風(feng)量(liang)的(de)計(ji)算(suan)請(qing)參(can)見(jian)橫(heng)向(xiang)式(shi)通(tong)風(feng)係(xi)統(tong)。因(yin)雞(ji)舍(she)縱(zong)向(xiang)式(shi)通(tong)風(feng)係(xi)統(tong)具(ju)有(you)設(she)計(ji)安(an)裝(zhuang)簡(jian)單(dan)、成本較低、通風和降溫效果良好等優點，在當代養雞生產上已廣為采用。
