It is important not to underestimate the influence of traffic in the garage on the required air flow. Local regulations and codes must always be adapted. The fresh air supply to a repair garage with 10 cars, floor area 150 m 2, volume 300 m 3 and a mean driving distance for the cars of 20 m - can be calculated as Required air changes per hourįresh air supply due to required 20 air changes per hour can be calculated asĬomparing the two calculations the fresh air supply should be at least 6000 m 3/h. Required air flow due to CO emission can be calculated asĬomparing the two calculations - the fresh air supply should be at least 1200 m 3/h. The fresh air supply to a storage garage with 10 cars, floor area 150 m 2, volume 300 m 3 and a mean driving distance for the cars of 20 m - can be calculated as Required air changes per hourįresh air supply due to required 4 air changes per hour can be calculated as
