Evapolar coolers work on the principle that water, when evaporating, absorbs the heat from the air. Due to that fact, it has a few requirements to work as efficiently as possible:
|Evapolar works best in dry air, as its working principle is turning hot dry air into a cool, moist one. If the humidity is higher than 70% (due to the area's climate, lack of ventilation in the room, etc), the temperature will not reduce significantly.
|If Evapolar is used in an enclosed space, it will gradually raise humidity while working and reduce its own effectiveness. Keep a window or a door open to prevent that.
|To feel the expected effect, you need to be in front of the device, within a 1-1,5m distance. It feels like a cool breeze on a hot day.
|If the water used contains high amounts of minerals or iron, it may leave a residue on the filter or change its color. It is not harmful to your health but may reduce the lifespan of the cartridge.
What do Evapolar coolers do, if you meet all these requirements?
What Evapolar coolers don't do?
|Cool the whole room (it can cool a really small enclosed space though, like a car or a tent).
|Allow you to regulate the outgoing temperature (as it depends on the ingoing temperature and humidity).
|Kill viruses and bacteria in your room.
The cooling potential for evaporative cooling depends on the relative humidity in the room and on the initial temperature. Hotter and drier air leads to a bigger difference in the temperatures. On the table below you can see the relation between air humidity and the temperature drop*.
