CAPACITY CALCULATION FOR ULTRASONIC HUMIDIFIERS
Note:
STULZ ULTRASONIC humidifiers atomize water into smallest water dro-
plets (< 0,001 mm).
The mist (aerosols) generated takes away heat from the ambient air (enthal-
py) and changes its state of aggregation from liquid to gaseous. Because of
this "adiabatic" behavior (heat absoption from the ambient air), the ambient air
in cooled down.
Example:
- Air conditon before humidification:
Temperature 25 °C
relative humidity 30 %
- Moisture addition of
∆
x= 3 g/kg
Condition of the air after humidification:
Temperature 18 °C
relative humidity 70 %
