Your fan's expected blow rate can be calculated from the amount of power it consumes and the pressure at which it works. The calculation will determine the fan's CFM value -- meaning how many cubic feet of air it displaces each minute. This value is essential to know when designing a ...
A system and method for controlling the exhaust flow rate in an exhaust ventilation system including an exhaust hood positioned above a cooking appliance. The method can include measuring a temperature of the exhaust air in the vicinity of the cooking appliance, and measuring a radiant temperature ...
