2.2. Operating principles

A good understanding of the principles is a precondition for the effective use of the unit:
The unit is designed to cut down condensation in rooms. The idea is to blow an appropriate and sufficient amount of air
at low pressure into the rooms that need to be treated. The principle involved is that air in motion dries walls (as seen in
industry, where this principle is applied to demist the windows of motor vehicles).
To understand the system's other process what has to be spelled out is indoor air is above all outdoor air that is moist
to varying degrees but as well as the moisture it already contains, the air absorbs the moisture
produced as a result of the rooms being used (steam from cooking, baths and showers, vapour emitted by
the human body, etc....).
Consequently, the ventilation system is used to renew the contaminated indoor air with fresh outdoor air as a result of
pushing the polluted air towards the vents designed for its evacuation.
When the outdoor air is heated prior to blowing the relative moisture ratio is reduced accordingly.
We know that the amount of moisture air may contain is directly related to its temperature, such that the warmer the air
the more water vapour it can hold. Hence the crucial importance of maintaining a steady temperature,
avoiding any significant variations (during the daytime / night time, for example, or occupied / empty rooms).
Any substantial reduction in the amount of heating required obviously saves energy but when a comfortable temperature
is restored more energy is consumed than necessary as a result of having to reheat all the structural elements and the
furniture.
The installer makes adjustments to the appliance in the light of the volumes in the rooms to be treated and the location of
the unit but is unable to take account of your lifestyle (how often the doors are opened, the capacity of various household
appliances to create water vapours, the extent to which the sanitation facilities are used).
You may adjust the various parameters to reflect your lifestyle, such as the setting of the temperature, airflow,
pre-programmed mode, etc...
The machine should run continuously in all cases to maintain constant movement.
