Evaporative Cooling

The fan is the core driving force of the evaporative cooling system. It promotes water evaporation and heat absorption through forced air flow, significantly improving cooling efficiency, temperature uniformity and environmental adaptability. The fan selection should focus on air volume/static pressure matching, environmental humidity adaptability and operation and maintenance convenience. EC variable frequency fan + indirect evaporative cooling solution is preferred to balance cooling and humidity control.

 

Ventilation and Coling Fan

  1. Forced air flow, accelerates the evaporation process

 

  • Promote water vapor exchange:
    The fan drives the air at a flow rate of 1.5-3 m/s through the wet curtain, spray water film or packing layer, expanding the contact area between air and water, and increasing the evaporation efficiency by 30%-50%.
    • Data: Under the conditions of dry bulb temperature of 35℃ and humidity of 30%, evaporative cooling can reduce the air temperature to 24-26℃.
  • Prevent humidity saturation: Continuous airflow carries away water vapor and maintains evaporation potential (avoid local humidity>80% causing evaporation stagnation).

 

  1. Temperature and humidity control

 

  • Precise temperature control: The variable frequency fan adjusts the speed according to the dry-bulb and wet-bulb temperature difference (such as full speed operation during high temperature periods) to maintain the outlet temperature fluctuation of ±1℃.
  • Humidity management: In the indirect evaporative cooling system, the fan separates the primary air (dry side) and the secondary air (wet side) to avoid excessive humidity in the supply air (such as reducing the humidity from 70% RH to 50% RH).

 

  1. Energy efficiency optimization and energy-saving

 

  • Natural cooling source utilization: In dry areas, fans only consume a small amount of electricity to replace traditional air conditioners (energy saving rate 70%-90%).
  • Partial load regulation: At night or under low load, the fan speed is reduced (energy consumption is reduced by 40%-60%), and intelligent algorithms are used to achieve on-demand cooling.
