改进粘胶长丝车间空调通风系统设计探讨

Discussion on Improvement of Air-Conditioning Ventilation System in Viscose Filament Workshop

按照纺丝机在1个工作日内或1个落丝周期内,排毒气系统处于开启时间或封闭时间分段计算,然后求该时段的平均值来确定粘胶长丝纺丝车间送风量,送风量是原设计的58.1%～65.8%;同时,通过采用纺丝机专用空气幕,改进车间空调通风系统,将空调系统改为机内重点、车间辅助的空调方式,节约空调新风能耗达25%～69%。

In accordance with one working day or a doffing period of spinning machine, sub-calculates operating periods and non-operating periods of the exhaust system in viscose filament workshop, then obtains average values of the periods to determine the air supply volum to the workshop. The supply air volum is 58.1% to 65.8 % of the former design. Meanwhile by means of applying the air curtain for spinning machine, improving the air-conditioning ventilation system of workshop and replacing the traditional air-conditioning model with ＂machine-focused and workshop subsidiary＂ model technology, saves the energy consumption of air-conditioning by 25 % to 69 %.
