An industrial building can house work areas or simply storage areas, so the amount of stale air will depend on the activity carried out, the size of the warehouse and the number of people working inside.
An amount of renovations/hour must be carried out according to the volume of m3 of the space to ventilate. The objective is to change the indoor air of that space for new air several times every hour: about 4 renovations/hour if the area has an unspoilt environment (due to its low activity, like a warehouse), even though it is large; or about 10 renovations/hour if it is a small area but with an activity that leaves a highly polluted environment.
In an industrial building there are different types of ventilation needs (exhaust or supply), different types of installations (duct, wall or roof) and very diverse applications. In this interactive infographic we summarize the most common and for which Casals has a solution for the correct ventilation of the industrial warehouse:
