In this paper, high-performance and low-noise centrifugal fan used to circulate cold air inside a household refrigerator is developed by reducing the vortex flow observed near the tip of fan hub. First, the performance of the existing centrifugal fan is investigated through the experiment using a fan tester and the characteristics of detailed flow field obtained from the CFD simulation are .Energy Saving: Opportunity Identification and Optimization . Many existing ventilation systems often have great potential to reduce power consumption by increasing the efficiency of the system (not only the fan but the whole system). A higher energy efficiency system usually comes together with lower noise emission from flow separation and blade

Zhu Zhi-xi, The aerodynamic design of low-noise capability centrifugal fan, Fluids Engineering, 1988, PP:16-19. [3] Stitute of Shenyang air blower and the fluid machinery department of northeast institute. Centrifugal fan, Beijing: China Machine PRESS, 1980. ulation is adopted to design centrifugal fan blades.Compact centrifugal cooling towers were built by using fill packs with a large thermal exchange-specific surface and therefore high-density ducts. Air-in and air-out ducts were often fitted with elbows and reducers and also, whenever necessary, with splitter sound attenuators to reduce system noise when in function.
Air Volume vs. Pressure: Choose axial fans for moving large volumes of air at low pressure. Opt for centrifugal fans for high-pressure applications with ductwork. Space Constraints: Axial fans are smaller and lighter, ideal for space-constrained environments. Noise Considerations: Axial fans might be quieter, though some centrifugal fans are .
