Indirect Evaporative Cooling Systems

A two stage idec thus is able to offer substantially cooler supply air temperature lower moisture content also consumes lesser water.

Indirect evaporative cooling systems.

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. Energy labs has been building indirect evaporative cooling for over 30 years. Arctic indirect evaporative cooling systems idec uses high efficiency dri cool module first stage which achieves the indirect evaporative cooling using water evaporation without increasing humidity in supply air.

Over the years we have designed systems with eer s exceeding 100. Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate. Our indirect evaporative cooling allows engineers and owners to get the efficiency benefit of water evaporation without concern for water carryover into the building. Spray humidifiers deliver moisture to an atmosphere using either high pressure or compressed air to ensure evaporation.

Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. Evaporative cooling systems are characterised by low energy use compared with refrigeration cooling.
