3. Cooling Effect and Humidification
Cooling Effect
A pleasant and cost-saving side effect of DRAABE direct room air humidification is the room temperature reduction achieved by adiabatic evaporation cooling. The complete absorption of the microfine, atomised water droplets in the air causes heat to be drawn from the room. The principle of adiabatic evaporation cooling can be likened to "perspiration". Beads of perspiration evaporate on the skin. The heat this requires is drawn from the atmosphere. The skin cools down.
The adiabatic cooling effect induced by humidification can support the use of an air conditioning system and even replace it depending on the local conditions. The room temperature can be reduced by an average of 2°C to 5°C. A cooling output of 640 W can be achieved for every kilogram of water evaporated in one hour via the nozzle humidifier. Converted to an air humidity plant with an output of 100 kg/h, this gives a cooling output of 64 kW.
Compared with the 0.6 kW of energy expended by the high-pressure pump employed on the high-pressure nozzle humidifier, the energy balance of the adiabatic cooling is extremely positive and economically appealing.
