3. DEFINITION OF TERMS
HUMIDITY
Humidity is the proportion of water vapor in the air.
DEW POINT/DEW POINT TEMPERATURE
The dew point or the dew point temperature is the temperature at which the
airborne water vapour will condense to form liquid water.
ABSOLUTE HUMIDITY
The absolute humidity is the proportion of water vapor and is expressed in
grams per cubic meter (g/m³).
Values between 0 g/m³ and a maximum value, depending directly on the air
temperature, are possible. When the maximum humidity is exceeded, some of
the water will condense, often the cause of damp room walls. Condensation
can also occur if the air temperature is cooled and the maximum humidity value
falls below the actual humidity.
RELATIVE HUMIDITY
The relative humidity indicates to what percentage the absolute humidity
exhausts the maximum humidity level. If a relative humidity of 100% is exceeded,
the excess moisture can cause, e.g. condensation.
