5.3 Steam installation 5.3.1 Positioning and mounting of the steam distribution pipes The location for the steam distribution pipes should be determined at the time of dimensioning the air conditioning system. Please note the following instructions to ensure proper humidification of the duct air. Calculating the humidification distance The water vapor, emitting from the steam distribution pipes, requires a certain distance to be absorbed by the ambient air so that it is no longer visible as steam.
Minimum distances to be observed To prevent the water vapor, that is emitting from the steam distribution pipe, from condensing on downstream system components, a minimum distance to the steam distribution pipe must be observed (depends on the humidification distance “BN”).
In positioning the steam distribution pipes, the following dimensions should be observed.
5.3.2 Positioning and mounting of the fan unit The fan unit is mounted on the wall separately above the unit. To allow the steam coming from the fan unit to spread out evenly, without condensing on obstacles (ceilings, joists, pillars, etc.), the following minimum dimensions must be observed when selecting the location for the fan unit or units N4 with integrated fan.
