What is Evaporative Cooling? Evaporative cooling myths

Evaporative cooling myths:
 

Myth: Evaporative coolers are just the same as swamp coolers.
Reality: While evaporative coolers use the same principles as the swamp coolers of yesteryear, evaporative coolers have evolved to become much more energy efficient and effective. The true difference in efficiency is in the pads -- or, to the technical among you, the rigid media. 

Port-A-Cool® units offer true differentiation because they use KUUL® pads, the strongest, heaviest pads on the market. They are especially effective in producing the most efficient cooling as they maximize the interaction between air and water. Evaporative coolers that utilize KUUL pads can lower temperatures as much as 7 degrees Celsius for an hourly operating cost of 0.05€ to 0.12€ (depending on the size of the Port-A-Cool unit; our units cover between 500 to 4,000 square feet).

Myth: Evaporative cooling units must use a lot of energy and/or cost a lot to run.
Reality: Evaporative coolers are among the most energy-efficient cooling methods available. Many of our coolers only pull the amount of electricity used to run a toaster.
 

Myth: Evaporative cooling works the same way an air conditioning (A/C) unit does.
Reality: No. Evaporative cooling is easier on both the environment and the pocketbook because it’s a green, natural source for cooling that runs on tap water without the use of harsh chemicals/refrigerants. Air conditioners have compressors that require a place to ventilate the heat generated from the compressor. Unlike an air conditioning system, a portable evaporative cooling unit does not require fixed ductwork for ventilation. They actually work best in large open areas like warehouses or even outdoors. In this way, Port-A-Cool units are highly portable and effectively cool areas where air conditioning is impractical and/or cost-prohibitive.

Myth: Since evaporative coolers use water, they must be essentially some form of a mister or a misting system.
Reality: No. Evaporative coolers do use water, but they don’t get you wet or spray liquid. Whether you’re feet away or right up close, what you get from an evaporative cooler is a refreshing and chilled breeze!

Myth: Evaporative cooling won’t work in humid climates or environments.
Reality: While it’s true that it’s easier to achieve significant temperature drops in more arid climates and drier spaces, evaporative coolers do still offer relief from the heat. This is where believing scientific fact, rather than myth, can help keep you cool! Even in regions where relative humidity reaches 80% at midday with temperatures over 25 degrees Celsius, evaporative coolers have been shown to offer significant relief.
