Description
The Companion Lithium Rechargeable Mini Evaporative Cooler is the perfect way for cooling down during the hottest seasons. This compact and lightweight rechargeable evaporative cooler is an ideal solution for your portable cooling needs with two fan speeds and oscillating function. An evaporative cooler is a device that cools air through the evaporation of water. Evaporative cooling differs from typical air conditioning systems which use vapor-compression or absorption refrigeration cycles. Evaporative cooling works by employing water's large enthalpy of vaporization. The temperature of dry air can be dropped significantly through the phase transition of liquid water to water vapor (evaporation), which can cool 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 the comfort of occupants.
