當(dāng)濟(jì)南排煙罩在運(yùn)送空氣進(jìn)程巾冷熱量損耗大又請(qǐng)求空氣溫度堅(jiān)持穩(wěn)定,或許要避免風(fēng)管穿越房間時(shí)對(duì)室內(nèi)空氣參數(shù)形成影響或排出的氣體在排入大氣前可能披冷卻而形成凝聚物堵塞或腐蝕風(fēng)管及螺旋風(fēng)管外表可能有結(jié)露時(shí),需對(duì)風(fēng)管進(jìn)行保溫.一般保溫層有防腐層保溫層、防潮層和保護(hù)層四層結(jié)構(gòu).

　　When the smoke hood in Ji'nan shipping air cold towel process high heat loss and requests for air temperature to maintain the stability, perhaps to avoid the formation of impact on the indoor air parameters of the wind pipe across the room or when the exhaust gas discharged into the atmosphere in front with cooling and the formation of condensate blockage or corrosion of the air duct and spiral duct appearance may have condensation. In need of insulation of air duct. The general insulation anti-corrosion insulation layer, moisture-proof layer and protective layer four layer structure.

　　通風(fēng)管道斷面形狀有圓形和矩形兩種.在相同斷面積條件下螺旋風(fēng)管因周長(zhǎng)短而經(jīng)濟(jì),在相同風(fēng)量下矩形風(fēng)管比螺旋風(fēng)管壓力丟失要大因而般狀況下都選用圓形風(fēng)管,只要有時(shí)為了便于和建筑配臺(tái)才選用矩行斷面.

　　The ventilation pipe section shape is circular and rectangular two. In the same fault because of perimeter short and most economical spiral duct area, in the same air flow rectangular duct like conditions and lost to use circular duct than spiral wind pressure, and sometimes as long as in order to facilitate the building with Taiwan was selected for the moment section.

　　由矩形風(fēng)管壓力丟失計(jì)算式可得出:矩形風(fēng)管的壓力丟失隨風(fēng)管寬高比增大而相應(yīng)增大.因而.設(shè)汁時(shí)應(yīng)使其寬高比接近于l.當(dāng)然有時(shí)候要看現(xiàn)場(chǎng)狀況.

　　The pressure loss formula of the rectangular air duct shows that the pressure loss of the rectangular duct increases with the increase of the aspect ratio of the duct, so the width ratio of the rectangular duct should be close to that of L., of course, depending on the site conditions

　　通風(fēng)、空氣調(diào)節(jié)體系的風(fēng)管,宜選用螺旋風(fēng)管.長(zhǎng)短比不大4的矩形截面,其大長(zhǎng)短邊之比不該超越1O,風(fēng)管的截面尺度,宜按現(xiàn)行標(biāo)準(zhǔn)通風(fēng)與空氣調(diào)節(jié)工種施工質(zhì)量驗(yàn)收規(guī)范的規(guī)定履行.

　　Duct ventilation, air conditioning system, should use the spiral duct. The length ratio of 4 small rectangular section, the maximum length of edge ratio should not exceed 1O, cross section scale wind tube, should according to the current standard of ventilation and air conditioning provisions of national code for acceptance of construction quality of work performance.

　　排煙管道因?yàn)橐┻^(guò)修建梁而使管道通風(fēng)截面積變小,截面上阻力增加,構(gòu)成氣流不曉暢，排煙管道在穿過(guò)修建梁或逃避其它設(shè)備管道時(shí),排煙管道中的一段會(huì)低于全體排煙管道平面.在運(yùn)用一段時(shí)間后,因?yàn)橛退旌衔飼?huì)積聚在較低的那段排煙管道中,直接影響排煙曉暢.

　　The exhaust pipe passes through the beam because building ventilation pipe cross-sectional area smaller, increasing section resistance, which don't know air exhaust pipe in the construction, through the beam or escape from other equipment pipeline, an exhaust pipe will be lower than the plane of the exhaust pipe. In use after a period of time, because the mixture of oil accumulation in the exhaust pipe in the low smoke, directly affect the smooth.
