Indirect Evaporative Cooling Systems

Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate.

Indirect evaporative cooling systems.

Spray humidifiers deliver moisture to an atmosphere using either high pressure or compressed air to ensure evaporation. Direct air evaporative cooling for buildings and areas that do not have a central air conditioning system direct air evaporative cooling can be a very economical and achievable way to reduce the temperature. An evaporative cooling system consists of an intake chamber filter s supply fan direct contact or indirect contact heat exchanger exhaust fan water sprays re circulating water pump and water sump. An evaporative cooler also swamp cooler swamp box 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. Energy labs has been building indirect evaporative cooling for over 30 years. A two stage idec thus is able to offer substantially cooler supply air temperature lower moisture content also consumes lesser water. The main difference with an indirect system is that a heat exchanger is used to cool the air supplied to the living space.

Evaporative cooling systems are characterised by low energy use compared with refrigeration cooling. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.
