摘要
为了研究通风机变频调速技术节能效果,分析了变频节能原理:当通风机排风量减小时,转速降低,通风机的轴功率按转速的三次方降低,从而达到变频调速节能目的。设计了通风机变频系统方案,分析得到了该方案通风机最佳工矿点转速为500 r/min,效率提高了24%。分别分析节电量、节电率、经济效益和环保效益对采用变频调速技术进行节能的验证效果,显示节能效果明显。
In order to study the energy-saving effect of variable frequency speed regulation technology of ventilator, the principle of frequency conversion energy saving is analyzed: when the exhaust volume of fan is reduced, the rotational speed is decreased, and the shaft power of fan is reduced to the third power of rotational speed. In order to achieve the purpose of energy saving frequency conversion speed regulation. The scheme of fan frequency conversion system is designed. The optimum speed of mine fan is 500 r/min, and the efficiency is improved by 24%. The efficiency of energy saving, power saving, economic benefit and environmental protection are analyzed respectively. The results show that the efficiency of energy saving is obvious.
