Brief note on humidity
Air always contains a certain amount of water in the form of water
vapour.
This amount of moisture is commonly known as the humidity.
The capacity of the air to hold water vapour increases with the
temperature.This is why in our homes, as soon as the temperature
decreases, the vapour contained in the air condenses, as is evident
on the colder surfaces in the room, such as the windows, walls etc.
The purpose of a dehumidifier is to remove the excess moisture
from the air, to control condensation within the home.
Experts have established that the optimum environmental condi-
tions for our well being and to preserve objects are obtained
between 40% and 60% relative humidity. Below these levels the air
can feel too dry and may cause skin complaints and even static
electric shocks.
If temperatures in the home are lower than 10°C for prolonged
periods low level heating will be necessary to allow the condensate
to evaporate into the air before dehumidification can take place.
The air will however be slightly warmed by the dehumidifier as the
dry air leaving the dehumidifier is about 1°C higher than normal
room temperature.
