How many ventilators are required for a particular application?

To determine the quantity of required ventilators we need to ascertain the following:

a)      Volume: Volume of shed to be ventilated.

b)      Air changes: Depending on the use of the particular shed to be ventilated choose the “ number of air changes per
  hour” required. The accompanying table gives guidance to determine number of air changes suitable to your application.

c)      CFM of ventilator: Refer table given below.

To Determine Number of Ventilators Required:

{(Volume of shed X No. Of Air Changes) / 60} / Exhaust Capacity of Ventilator.

Volume of Shed = Length X Width X Height
 
Conversions:

1 Ft = 0.3048 Mtrs
1 Mtrs = 3.2808 Ft
1CFT = 0.028317 CUM
1 CUM = 35.315 CFT
