The demand for household appliances, such as air conditioners, has surged in response to frequent heat waves. Consequently, the need for efficient and quiet axial fans has grown, aiming to minimize carbon emissions and power consumption. Building on research from MIT regarding toroidal propellers, we embarked on designing and manufacturing toroidal-shaped axial fans. These toroidal fans, along with a reference fan for benchmarking, were fabricated using an SLA printer and subsequently affixed to a DC motor. Comprehensive measurements were carried out, including flow velocity, RPM, and power input using an anemometer, tachometer, and power supply readings, respectively. Noise levels were recorded with a microphone and analyzed with digital audio workstation (DAW) software. Our findings indicate that toroidal fans can generate flow velocities comparable to those of traditional axial fans. However, further investigations are warranted to assess their flow rate characteristics, and attention must be given to varying noise levels associated with different frequencies.
