Keep freezing temperature of working place is important for food manufactures. In the winter, stratification occurs because air coming out of a heater is 5-7 percent lighter than cool air in a space and tends to rise to the ceiling. In the winter, large diameter fans can be used to efficiently destratify heat by moving large volumes of warm air downward and off the ceiling without creating a draft. The steady mixing of air creates a uniform temperature throughout the space, which can help the heater maintain the same thermostat setpoint with less effort, resulting in a serious reduction of operating costs.

 

Refrigerated production and storage facilities can use such fans to eliminate hot and cold spots in the facility, enabling managers to use the entire space.

 

In large spaces, HVAC systems are generally not capable of effectively distributing air to all occupants.Large circulator fans mix the air in the space ensuring good air distribution, creating uniform temperatures that increase occupant comfort and minimize stratification.

 

Because these big fans use their immense size, rather than speed, to move a substantial amount of air, they require minimal electrical input to run.

 

Large fans can be added to many existing structures, where they often are used to help qualify the building for energy-saving incentive programs. In new construction, specifying large fans when the HVAC system is designed can also help facilities eliminate a significant amount of ductwork, saving on initial building costs before the fans are ever turned on.
