The electronic COMFORT CONTROL Thermo-Hygrometer is an ideal measur-
ing instrument for checking room ambient conditions.
Excessive room-air humidity can damage your health and promotes the
formation of damp patches and mould.
But excessively dry room air can also affect our well-being and health in
various respects. Skin, mucous membranes and airways are adversely
affected and pets, house-plants, wooden flooring and antique furniture
may also suffer.
Active heating and ventilation can help achieve a comfortable and
healthy living environment and may even save you heating costs.
The interaction of temperature and air humidity:
If the room air is too humid, ventilation would at first appear nonsensical
in the winter, when the outside air is also cold, damp and just as humid.
Cold air however, can absorb little or no moisture. When this air enters
the living areas it becomes warmer. And then the air can absorb much
more water vapour. After just a few minutes of giving a room an airing,
you can see on the digital display how the relative humidity goes down.
Dew-point:
This interdependency of temperature and relative humidity is expressed
by means of the dew-point:
If the air is cooled continuously at constant absolute humidity, then the
relative humidity will steadily increase up to a maximum of 100%. If the
air is cooled further, then the excess water vapour is separated out in
the form of water droplets.
If the measuring unit indicates an air temperature of 20° C and a relative
humidity of 65%, then the dew-point temperature will be 13.2° C. What
does that mean? That the air, for instance in your bedroom, will con-
dense and form water droplets at all points on walls and ceilings that are
cooler than 13.2° C, and that this may later lead to patches of mould or
damp.
If the air is at a relative humidity of say 40%, then the dew-point tempera-
ture is only 6 °C. The walls and ceilings would therefore have to be signif-
icantly colder for the air to reach its dew-point and for water droplets to
form.
How to achieve the correct temperature and air humidity:
Tips for active heating and ventilation:
• Check the dew-point! Surfaces of walls should not fall below a tempera-
ture of 15° C!
