AHU

The fan plays the role of the core power source and airflow control center in the AHU (air handling unit), directly affecting the air handling efficiency, energy consumption level and system stability.

 

Ventilation and Coling Fan

  1. The fan provides forced airflow power for the AHU, ensuring that the external fresh air and the indoor return air are mixed in a set ratio and flow through the filter, temperature and humidity treatment module.

 

  • Data: The centrifugal fan can provide 1000-3000 Pa static pressure to overcome the duct resistance and filter pressure drop (primary efficiency + high efficiency filtration pressure loss is about 150-300 Pa).

 

  1. Adjust the air volume and pressure

 

  • Air volume control:
    The fan speed is adjusted through the variable frequency drive (VFD) (such as 20-100% stepless speed change) to match the load demand (such as reducing the frequency at night to save 30%).
  • Pressure balance:
    Maintain the static pressure of the AHU outlet stable (such as 500±50 Pa) to prevent uneven air supply due to pressure fluctuations at the terminal air outlet.

 

  1. Improve the uniform flow field of heat exchange efficiency:
    Optimize the fan impeller and guide design to ensure that the air flows evenly through the heating/cooling coil (temperature difference ≤1℃) to avoid insufficient local heat exchange.
  2. Support filtration and purification

 

  • Penetration guarantee: Maintain sufficient wind speed (1.5-2.5 m/s) to allow air to penetrate high-efficiency filters (such as H13), with a capture efficiency of ≥99.95%.
  • Self-cleaning function:
    Some AHUs are equipped with reverse pulse cleaning fans to regularly remove dust from filter bags (pressure drop recovery rate ≥90%).
