摘　　要：以某深地空间长距离送风系统为例,采用Ventsim软件计算了4种风量调节方案的系统风机风压与管道阻力的变化,提出了增加干管风机数量和改变进风竖井位置2种优化方法,分析了送风系统管网阻抗与等积孔面积的变化。结果表明,优化后送风系统的管网阻抗和等积孔面积分别最大降低0.102 kg/m^(7)和0.030 m^(2),科学的送风方案既能满足风量需求,又能降低长距离送风系统的阻力,具有较好的节能与经济效益。Taking a long distance air supply system in a deep-earth space as an example,Ventsim software is used to calculate the changes of fan pressure and pipeline resistance of four air volume adjustment schemes,two optimization methods of increasing the number of main pipe fans and changing the position of the air inlet shaft are proposed,and the changes of pipe network impedance and equivalent orifice area in the air supply system are analyses in this paper.The results show that the pipe network impedance and equivalent orifice area of the optimized air supply system can be reduced by 0.102 kg/m^(7) and 0.030 m^(2),respectively.The scientific air supply scheme can not only meet the air volume demand,but also reduce the resistance of the long distance air supply system,which has good energy saving and economic benefits.
