Employees changed fan settings at will?
A food warehouse had installed HVLS fans, but did not control them with a central system, nor did they integrate their exhaust fans or louvers into the fan system. The HVLS fans created a comfortable breeze for employees in this southern warehouse, but the fans were controlled by the employees at their will.
With 4SIGHT iFAN …
Exhaust fans and louvers are integrated with the HVLS fans into a central 4SIGHT iFAN system so that on cool evenings and nights, the HVLS fans could be turned off, the louvers opened and the exhaust fans turned on. The exhaust fans could draw out the hot air of the day and pull in fresh cool air through the open louvers. This system remains on until temperature probes sense 80 degrees Fahrenheit at 6 feet off the finished floor, at which point, iFAN closes the louvers, turns off the exhaust fans and turns on the HVLS fans to mix the cool air, now effectively trapped in the warehouse. The iFAN system creates more comfortable employees while also being more cost effective.
