EVAPORATIVE COOLER
Question
Answer
How much windows
should be opened?
To provide efficient cooling or ventilation the building must have sufficient
exhaust openings to the outside of the building. To assist in airflow, open
windows and outside doors that are farthest from the outlet vent in each room
that has a vent installed. In the rooms that have vents you should provide an
exhaust to the outside of the building approximately 2 times the opening area
of the vent.

Can we fully open up the
windows?
If you open the windows too much you could reduce the cooling effect because
you may also let the hot air in. Also on occasions of hot winds you may need
to reduce the openings on the windward side of the house and increase the
openings on the lee side to compensate.

Can we vary the amount
of cooling in any one
area by decreasing other
areas?
Yes one of the principles of evaporative cooling allows you to do this, by the
air from the outlets always taking the path of least resistance to escape the
building. So with this in mind you can close the window in a room and open
the internal door so the cool air can exhaust through to another area where
an external opening has been provided. We recommend you experiment so
you can get the best out of your cooler. But always remember the air from the
outlets must be exhausted somewhere to the outside of the building in order for
the unit to work effectively.
It’s a very humid day/
night and the cooler does
not perform, as I would
normally expect – why?
An evaporative cooler uses the evaporation of moist air to produce a cooling ef-
fect. So when the air is very moist and the ambient humidity of the day is high,
evaporation levels will be low. Thus, the cooling effect is reduced due to the
cooler not being able to evaporate sufficiently. In some situations it may prove
beneficial to switch the cooler to ventilation and run the fan on a high speed.
I am getting hot air from
the vents – why?
Check that the wall control is set to the cool mode and that the water supply to
the unit has not been turned off. Also in days during summer when the ambient
humidity is high, the cooler will not reduce the temperature as much as on drier
days.
I get too much air through
some grills and not
enough through other
grills. How can I change
this?
You need to contact the company who installed the system and ask them to
balance your airflow within the ductwork. This cannot be achieved by any
adjustment on the cooler
