1. Advantages of axial flow fan:

1) Good cooling effect;
2) Low unit energy consumption is particularly important in today's advocacy for energy conservation;
3) Easy to control the timing of ventilation and prevent condensation from occurring;
4) No need to equip a separate fan, convenient and flexible.

2. Disadvantages of axial flow fans: Due to low air volume and long ventilation time, the precipitation effect is not significant, and axial flow fans are not suitable for ventilation with high moisture content.

3. Advantages of centrifugal fans: significant cooling and precipitation effects, short ventilation time;

4. Disadvantages of centrifugal fans: high unit energy consumption; Poor timing of ventilation can lead to condensation.
