Indirect Evaporative Cooling Systems

Energy labs has been building indirect evaporative cooling for over 30 years.

Indirect evaporative cooling systems. Evaporative cooling systems are characterised by low energy use compared with refrigeration cooling. 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. Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles.

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 uses the fact that water will absorb a relatively large amount of heat in order to evaporate. Over the years we have designed systems with eer s exceeding 100. 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.

Our indirect evaporative cooling allows engineers and owners to get the efficiency benefit of water evaporation without concern for water carryover into the building. A two stage idec thus is able to offer substantially cooler supply air temperature lower moisture content also consumes lesser water.
