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.or direct evaporative cooling, the direct saturation efficiency, , measures in what extent the temperature of the air leaving the direct evaporative cooler is close to the wet-bulb temperature of the entering air.
Direct and Indirect Cooling Systems. Any surface of heat transfer in which volatile liquid expands and evaporates to produce a cooling effect is called direct expansion evaporator. Liquid absorbing die thermal energy is called direct expansion of the refrigerant.
