空调风机的改造与节能

Reformation and Energy Saving on Draft Fan of Air Conditioner

棉纺织厂空调风机消耗能量占总能耗的 1 5% ,使用新一代先进翼型节能轴流风扇叶轮进行风机改造 ,可以收到节能、降噪的效果 ,一台 50A型№ 2 0轴流风机经改造后风量增加 96% ;全压提高 57% ;效率提高64.6个百分点 ;轴功率下降 1 0 % ;噪声降低 6.9dB(A) ;仅风量增一项创造的经济效益每年可达 5万余元。

The energy consumption of conditioner fan occupied 15% of total energy consumption.We can obtain the effect of energy saving and noise reducing using new advanced wing section axial-flow fan impeller on reforming the fan,after reforming a 50A No20 axial-flow fan,the Wind Capacity can increase 96%,the Noise can reduce 6.9 dB(A),the Total Pressure can increase 57%,the Efficiency can increase 64.6 percent and the Axle Power can reduce 10%,only the increasing on wind capacity could create the benefit about $50 000 per year.
