5.0 Functioning notes
The functioning of the evaporative cooler is based on an important principle: It introduces big
quantities of fresh air into the building and removes hot exhausted air through doors, windows and
other openings. If the system is not able to expel the air volume introduced into the building, the
efficiency would be compromised. INLET FRESH AIR = OUTLET HOT AIR: a very simple principle.
If the system is able to expel all the air introduced into the building, the system operates at the
highest efficiency. The ideal condition is when, into the building, the air diffusers are positioned away
(better on the opposite side) from the openings (windows, doors, etc.) so the air passes through
the building while cooling it. Maximum efficiency can be reached by adjusting the dimensions of
the window and door openings. Never close the openings: if they are closed, no changes of air will
occur, consequently reducing the cooling effect and increasing the relative humidity level inside the
building.
