1、隧道通風(fēng)的禽舍靜壓一.隧道通風(fēng)禽舍結(jié)構(gòu)尺寸，i般長寬比10:1.二.隧道通風(fēng)多為負(fù)壓式通風(fēng)，有橫向與縱向通風(fēng)之分三.對于橫向通風(fēng)雞舍內(nèi)部的任何位置靜壓值都相等四.只有縱向通風(fēng)，沿雞舍縱向不同位置靜壓值會有不同值五.橫向通風(fēng)需要時刻關(guān)注舍內(nèi)靜壓六.縱向通風(fēng)不需要時刻關(guān)注舍內(nèi)靜壓，但是可以以此判定設(shè)備運(yùn)行狀況七.縱向通風(fēng)雞舍靜壓的組成1.濕簾阻力Howdowedeterminepadarearequiredtokeeptheincomingpressurebelow0.06”？?Withpadstaticpressurecurves515
