Adiabatic humidification
The adiabatic humidification process involves the direct evaporation of water in the air without the addition of energy from the outside: the water is finely atomised to maximise the heat exchange surface and then introduced into the environment.?
The heat required for vaporisation is not supplied by external sources, but rather by the air being humidified, which as a consequence is cooled.?
The power consumed by the mechanical action of adiabatic humidifiers is therefore quite low.
