Page 28: Positioning Of The Steam Distributor
5.4.2 Positioning of the steam distributor The location of the steam distributor should be determined at the time of dimensioning the air condition- ing system. Please note the following instructions to ensure proper humidification of the duct air. Calculating the absorption distance The steam, emitting from the steam distributor, requires a certain distance to be absorbed by the air so that it is no longer visible as steam. - Page 29 Example given 1= 30 %rh, 2= 70 %rh φ φ 1,4 m absorption distance B (0.36 m for steam distribution system MultiPipe) Note: If the absorption distance has to be reduced for technical reasons, the amount of steam per unit must be divided between several steam distribution pipes or the steam distribution system MultiPipe must be used.
