Comparison of Ventilation Effects Between Centrifugal High-Pressure Fans and Axial Fans?

Commonly used fans include centrifugal high-pressure fans and axial fans. What are the differences in their ventilation performance? Analysis indicates that centrifugal high-pressure fans offer faster air exchange and cooling speeds but consume more electricity, while axial fans provide slower ventilation and cooling rates but use less power. The appropriate fan selection depends on regional conditions. Axial-flow air cooling possesses distinct advantages: it reduces water loss, lowers ventilation costs, and enhances ventilation efficiency. Through experiments, we conclude: Centrifugal high-pressure fans excel in rapid cooling but exhibit lower ventilation efficiency. Axial-flow fans feature low energy consumption per unit but slower cooling speeds. Both types have their respective strengths and weaknesses. Test results indicate that centrifugal high-pressure fans achieve rapid air exchange with high static pressure but incur significant moisture loss. Axial-flow ventilation operates at low airflow volumes and slow velocities, resulting in minimal water loss. From an operational cost perspective, axial fans consume only one-third the energy per ventilation unit compared to centrifugal high-pressure fans, yielding significant cost savings. Furthermore, axial fans require only the fan itself to operate during ventilation, eliminating the need for manual intervention or multiple personnel to protect the fan during air exchange. Under identical operating conditions, axial fans consume substantially less energy than centrifugal high-pressure fans.
