Ecofresh - Rafraichisseur d'air par évaporation

Adiabatic Evapotative Cooler


The fundamentals of evaporative bioclimatization

Constant air change


In order to obtain an optimum evaporative result, the air sucked from the outside that is blown into the room must be extracted as quickly as possible, naturally by opening a door, a window or a grating. of decompression, is forced and dynamic by the establishment of an extractor of a flow equal to insufflation.

Finally, what is important is that the ECOFRESH bioclimatic room becomes an air circulation corridor at very low speed to avoid drafts.


Why renew the air so fast ?

Simply so that the fresh air ejected ECOFRESH bioclimator, for example at 24°C, can scroll in the room at the temperature closest to that of ECOFRESH without taking care of the thermal mass that is produced in the room (machine heat, human heat, hot and polluting steam...)

How often do you have to renew the air in the room ?

The value usually used is 20 times the volum of the building or room. For example, for a room of 400 m² with an average height of 5 m, ie a volume of 2000 m3, the need for renewal will be 20x2000 = 4000 m3/h. We will therefore choose 2 evaporative bioclimatisers of 20 000 m3/h or a single model of 40 000 m3/h. However, in each trade, the internal heat loads are different.

The humidity

It is understood that the humidity relative to the outside air relative to the dry bulb is an essential element for optimizing the results of the bioclimator ECOFRESH, adiabatic evaporative cooler.

Thus, as we explained previously, the more the outside air will be dry, the better the result will be. In hot summer, the average humidity of our regions is about 40 %. as a result, the bioclimatiic result of ECOFRESH is almost always exceptional with a temperature difference of nearly 10°C in many cases between the intake air and the blown air.
