Ceiling Displacement Diffuser DAV Propagation diameter Layout example: DAV-...-Z-500-... Mounting height = 4 m VZU = 600 m3/h AT = 4K Required: distance xA (m) xA distance at 600m3/h and AT= 4K = 0.92m Multiply by the corrrection factor of 1.38 (4 m mounting height). xA distance = 0.92 m x 1.38 Result: xA distance = 1.27 m The spacing of the diffusers should be selected such that the jets do not intersect.
