The air handling units (dehumidifiers and VMC) A|RADIUS allow for the completion of climate comfort functions according to the principles of Radiant Architecture at the most comprehensive level (Level III – see the “Radiant Climate Levels” sheet).
It is important to remember that the function of the dehumidifiers is NOT to prevent condensation on the panels (a function performed by the regulation independently of any type of air treatment) but rather to maintain a humidity level in the environment that ensures thermal comfort, even in cases of increased humidity from internal sources (e.g., people) or external sources (e.g., heat) to the building.
In the RADIUS system, dehumidification is carried out according to the BioSet logic, in which radiant temperature also plays a role in deciding when it is activated. This is because the need for evaporation from the body (and the body evaporates more when the humidity level is lower) also depends on the amount of radiation (and this occurs when the radiant temperature is lower, i.e., that of the surrounding surfaces).
In practice, with an average radiant temperature of 23°C, less dehumidification will be required than with a temperature of 25°C. This is why it is incorrect to activate dehumidification based solely on relative humidity, as it alone does not reflect the entire thermal exchange scenario available to the body in a specific context.
Thanks to this approach, dehumidification will be used more appropriately and economically.
