Quk Cul Ventilator

Quick Calculation : Calculations to decide the number of TURBOVNETS. Determine the volume of the building in Cubic Meter : Volume of Section A = 0.5 x L x W x Ha (all dimensions in Meters) Volume of Section B = L x W x Hb (all dimensions in Meters) Total building Volume = Volume of Section A + Volume of Section B Note : For Factories, the combined Volume A + B should be used. Calculate the number of ventilators required : Metric = V x Ach EXc x 3.6 Where : V = Volume of builidng roof space Ach = Air changes per hour (refer ACH table) EXc = Exhaust capacity of ventilator (refer Exchaust Capacity table above)
