HVLS Fans Wind Chill Effect

The gentle breeze brings by RTFANS HVLS fans to our body can accelerate sweat evaporation and make people feeling cool, usually, this sensible temperature created by wind chill effect can be 5-8℃, in addition, the gentle wind from all sides will make people more comfortable compared with a traditional powerful fan.

How to make people feel cooling down 5-8℃ by use high-volume low-speed fans?

The running of a big diameter industrial fan blade accelerates the airflow and increases the evaporative efficiency of the sweat on a human being’s body, and this evaporation process takes away heat in the body, that’s called wind chill effect.

As for the specific influence created by different wind speeds, please see the above graph, which can show you different temperatures with different wind speeds to make the difference that people feeling.
