Dimensioning of the humidification device
When dimensioning the humidification output that is mounted beyond the rotorsystem, the minimum outside humidity needs to be taken into consideration. When the outside air temperature increases after the set value of the supply air temperature has been reached, the rotorsystem is regulated down.
The rotorsystem runs in the regulated range with reduced speed or comes to a stand still and then transfers no or just a little moisture. The humidification device mounted beyond the rotorsystem has to be constructed in such a way that the required supplied air humidity can be reached even it the rotor is at a stand still.
