AHU in Data Centers

In the data center, the fan of the AHU (air handling unit) is the core equipment for maintaining precise temperature control, high-efficiency heat dissipation and stable operation, and is directly related to server reliability, energy consumption level (PUE value) and operation and maintenance costs.

 

Ventilation and Coling Fan

  1. Forced air circulation and precise temperature control to dissipate heat load:
    The power density of data center cabinets can reach 20-50kW/cabinet. The fan drives cold air through the raised floor or vertical air duct to remove the heat from the server (1kW IT load requires about 300m³/h air volume).

 

  • Case: Facebook's Arctic Circle Data Center uses EC fans for natural cooling, with a PUE as low as 1.07.
  • Temperature uniformity: Maintain the cold channel temperature at 22±1℃ (ASHRAE recommended range) to avoid local hot spots (temperature difference >3℃ will shorten the life of the server).

 

  1. Airflow organization optimization to prevent airflow short circuit:
    The fan cooperates with blind plates and baffles to guide cold air accurately into the cabinet air inlet, reducing bypass airflow (reducing cooling waste by 30%).

 

  • Dynamic adjustment: According to the changes in cabinet load (such as intermittent high load of AI training clusters), the variable frequency fan adjusts the air volume in real time (±10% accuracy).

 

  1. Redundancy and high reliability

 

  • N+1/2N configuration: Dual power supply EC fans or independent backup fans to ensure full load operation (MTTR<1 hour) in the event of a single point failure.
  • Dust prevention and filtration: Electrostatic dust removal (ESP) or MERV 13 filters protect servers from dust erosion (dust concentration <0.1mg/m³).

 

  1. Improved energy efficiency (lower PUE)

 

  • Utilization of natural cooling sources: Fan-linked indirect evaporative cooling (IWEC) or dry cooler, shut down the compressor in low temperature seasons, saving 50%-70% energy.
  • EC motor technology: Compared with traditional AC fans, EC fans (IE5 energy efficiency level) save 40%-60% of electricity consumption.
