Tips & Tricks

At all times, atmospheric air contains a certain amount of water in the form of an invisible water vapour. The exact quantity of water vapour in the air depends essentially on local and meteorological conditions, although a maximum threshold does exist, measured in g/m². Once this maximum amount has been reached, the air is referred to as "saturated" with damp and the rate of relative humidity is 100%.


It is also essential to remember that the rate of saturation of the dampness in the air depends to a great extent on the ambient temperature.

The greater the temperature of the air, the more water vapour it can hold; the lower that temperature, the smaller the maximum possible damp content.

Each time the temperature drops, condensation forms. For example, should saturated air at a temperature of 25 °C, with a humidity rate of 100% and with a water vapour content of 23.04 g/m³ cool down to 15 °C, then 10.22 grams of water per 1 m³ will need to be removed.
