Evaporative cooling works similar to our own bodies, using the evaporation of water to cool the air whereas our bodies use our own sweat to cool us down as it evaporates, we use about 1 litre of sweat a day.
This sweat evaporates as quickly as we produce it and as the heat rises so does the sweat. On a humid day our sweat increases and the humidity takes over and we can’t produce enough sweat to cool down.
Sweating is a normal function that helps the body cool down.
MUCH THE SAME IS THE EVAPORATIVE COOLER, IT WON’T WORK IN HIGH HUMIDITY
Evaporative coolers do not work in high humid conditions and the ability to cool the air effectively decreases. Whereas on the other hand although more expensive, air conditioners are able to cool the air no matter how high the humidity may be
WHEREVER THERE IS THE POSSIBILITY OF HIGH HUMIDITY FORGET ABOUT EVAPORATIVE COOLING
Weather patterns are changing in Australia, high humidity can be found where it was never thought of before. We are now in La Nina and heavy rainfalls are predicted and have been received for much of Australia. So there may be periods of high humidity where ever you are. So it is possible that you may think twice when choosing evaporative cooling over air conditioning.
Air conditioning may be the dearer of the two but it will work for you whenever you need it, summer or winter, no matter what the outcome of the season.
