The propeller blades of big HVLS fans can form a continuous and silent breeze only by rotating slowly. Its efficient airfoil blade can generate a large amount of downward flow when it rotates slowly, thus forming a propeller exhaust which is almost perfect.
1. The wind speed of big HVLS fans
The wind speed generated by the big HVLS fans is about 2-3 meters per second, which is calculated based on the amount of air flowing over the human skin to produce a cool feeling. Too strong airflow will make people feel hot in both body and mind, while the excessively high wind speed will also make people feel dizzy. Only through the combination of volatilization speed of the body surface and breeze speed can we improve the cool feeling on our bodies.
2. Applications of big HVLS fans
Big HVLS fans are widely used in industrial plants, logistics warehouses, waiting rooms, exhibition halls, stadiums, supermarkets, and other large spaces. The big air industrial fan is a common industrial machine, which is used for ventilation and cooling.
Big HVLS fans can push a large amount of airflow to the ground, and form a certain height of airflow layer on the ground to move horizontally, thereby promoting the overall air circulation, which is good to form the ground coverage and the three-dimensional circulation of air. Big HVLS fans have a maximum diameter of up to 7.3 meters. Manufactured by aerodynamic principles and advanced technology, its streamlined fan blades can drive a large amount of air with only 1.5KW, and generate a large area of natural breeze system for ventilation and cooling. Compared with traditional HVAC and small high-speed fans, it has unparalleled advantages in the application and is a solution for ventilation and cooling of large spaces.
