摘要: 将现有窗机送风系统,包括室内前向离心风扇、室外轴流风扇,替换为高效低噪送风系统:室内采用后向式离心风扇、室外采用边缘锯齿、凹凸表面的三叶片轴流风扇。通过上述方案,提高送风系统效率,实现性能保持不变情况下,室内噪音降低3dB,室外噪音降低4dB。

Abstract: Replace the existing window air supply system with an efficient air supply system, the existing window air supply system includes forward centrifugal fan and axial fan. The efficient air supply system includes backward centrifugal fan and three-blade axial fan with serrated edges and concave-convex surfaces. With the air-conditioning performance unchanged, the efficiency of the air supply system improved, the indoor noise reduced 3dB, outdoor noise reduced 4dB.
