Page 11: Functional Description
Functional description The steam humidifier Nordmann RC4/DC4 is a pressureless steam generator that utilizes an elec- trode heating. The steam humidifier Nordmann RC4/DC4 is designed for air humidification via a steam distributor (unit versions Nordmann DC4) or via the integrated ventilation unit (unit versions Nordmann RC4). Steam generation Any time steam is requested, the electrodes are supplied with voltage. Simultaneously, the inlet valve opens and water enters the steam cylinder from the bottom via water cup and supply line. As soon as the electrodes come in contact with the water, current begins to flow between the electrodes, eventually heating and evaporating the water. The more the electrode surface is exposed to water, the higher is the current consumption and thus the steam capacity. Upon reaching the requested steam capacity, the inlet valve closes. If the steam generation de- creases below a certain percentage of the required capacity, due to lowering of the water level (e.g. -

Page 27: Positioning And Mounting Of The Steam Distribution Pipe
5.3.2 Positioning and mounting of the steam distribution pipe 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 vapour, 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. This distance is referred to as humidification distance “B ” and serves as a basis for the determination of the minimum distances from the upstream components in the system. Humidification Expansion and mixing zone distance B ϕ1: Supply air humidity before humidification ϕ2: Supply air humidity after humidification The calculation of the humidification distance “B ” is dependent on several factors. For a rough estimation of the humidification distance “B ”, the following table is useful. Recommended standard... - Page 28 Minimum distances to be observed To prevent the water vapour, 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 “B ”). before/after constriction after expansion before bend before branch before diffuser before control sensor before/after filter/register before/after fan, zone exit 1.5 x B 5 cm 2,5 x B before aerosol filter Installation notes and dimensions The steam distribution pipes are designed for either horizontal installation (on the duct wall) or, with accessories, for vertical installation (in the duct floor). The outlet orifices should always point upwards and at right angles to the airflow. If possible, the steam distribution pipes should be installed on the pressure side of the duct (max. duct pressure 800 Pa). If the steam distribution pipes are installed on the suction side of the duct, the maximum vacuum must not exceed 800 Pa.
