當濟南麻豆国产视频罩在運送空氣進程巾冷熱量損耗大又請求空氣溫度堅持穩定,或許要避免風管穿越房間時對室內空氣參數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管及螺旋風管外表可能有結露時,需對風管進行保溫.一般保溫層有防腐層保溫層、防潮層和保護層四層結構.

　　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.

　　通風麻豆视频官网斷麵形狀有圓形和矩形兩種.在相同斷麵積條件下螺旋風管因周長短而經濟,在相同風量下矩形風管比螺旋風管壓力丟失要大因而般狀況下都選用圓形風管,隻要有時為了便於和建築配台才選用矩行斷麵.

　　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.

　　由矩形風管壓力丟失計算式可得出:矩形風管的壓力丟失隨風管寬高比增大而相應增大.因而.設汁時應使其寬高比接近於l.當然有時候要看現場狀況.

　　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、空氣調節體係的風管,宜選用螺旋風管.長短比不大4的矩形截麵,其大長短邊之比不該超越1O,風管的截麵尺度,宜按現行標準通風與空氣調節工種施工質量驗收規範的規定履行.

　　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.

　　麻豆国产视频麻豆视频官网因為要穿過修建梁而使麻豆视频官网通風截麵積變小,截麵上阻力增加,構成氣流不曉暢，麻豆国产视频麻豆视频官网在穿過修建梁或逃避其它設備麻豆视频官网時,麻豆国产视频麻豆视频官网中的一段會低於全體麻豆国产视频麻豆视频官网平麵.在運用一段時間後,因為油水混合物會積聚在較低的那段麻豆国产视频麻豆视频官网中,直接影響麻豆国产视频曉暢.

　　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.
