What’s evaporative air cooler
An evaporative cooler (also swamp cooler, desert cooler and wet air
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 building occupants.
Physical principles
Evaporative coolers lower the temperature of air using the principle of evaporative cooling, unlike
typical air conditioning systems which use vapor-compression refrigeration or absorption
refrigerator. Evaporative cooling is the addition of water vapor into air, which causes a lowering of the
temperature of the air. The energy needed to evaporate the water is taken from the air in the form of
sensible heat, which affects the temperature of the air, and converted into latent heat, the energy
present in the water vapor component of the air, whilst the air remains at a constant enthalpy value.
This conversion of sensible heat to latent heat is known as an adiabatic process because it occurs at a
constant enthalpy value. Evaporative cooling therefore causes a drop in the temperature of air
proportional to the sensible heat drop and an increase in humidity proportional to the latent heat
gain. Evaporative cooling can be visualized using a psychrometric chart by finding the initial air
condition and moving along a line of constant enthalpy toward a state of higher humidity.
