基于窗机送风系统优化实现整机流体降噪研究

Abstract

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.

Key words: Backward centrifugal fan, Axial fan, Noise
