With Summer around the corner, it is good time to think about cooling your space. This device is definitely not a solution to central cooling but is an invaluable tool for small spaces. The Evapolar Personal Air Cooler is a combination of air cooler and a humidifier designed for small, hot and dry places about the size of a desk, couch or a single bed. It might, however, lose effectiveness when the ambient air gets hot and humid. It cools air through the evaporation of water by exploiting water’s large enthalpy of vaporization. The temperature of dry air is dropped significantly through the phase transition of liquid water to water vapor (evaporation). This cools air using much less energy than refrigeration. In extremely dry climates, evaporative cooling of air has the added benefit of conditioning the air with more moisture for comfort.
This is a small portable USB-powered air cooler/conditioner that cools air in the same way the air is cooled in nature. Under ideal conditions, it can bring up to15C. The air that comes out is also humidified and cleaned for breathing. Light, portable, silent and energy efficient, it consumes only 10W of electricity and is perfectly safe for children and pets.
The removable tank can take water enough for 6 to 8 hours of continuous cooling. The secret to low energy use is that no water pump is required to circulate water. No special need for installation; can be used anywhere as needed.
This portable and compact device will cost you only $175.
