What's inside?
The aim of this paper is to present the design of an axial fan able to reach the demanded performance with high efficiency and low noise emissions. The optimization process that leads to an efficient blade is discussed, in order to show the geometry and the fluid-dynamics performances. Then, the resulted blade will be tested by means of numerical simulations to assess the structural and acoustic performances.
The first stages of the design of an axial fan for heat pumps are described in this paper. The performance of the impeller are evaluated. Under the fluid-dynamics point of view the fan is in line with the requirements and does not need further improvements.
In this publication, you will:
- Discover the methodology to design the impeller by respecting the imposed project targets;
- Understand how the designers have been evaluating the acoustic spectrum;
- See how to generate a new design that will enable the reduction of CO2 emission.
