Indirect Evaporative Cooling Heat Exchanger

1 indirect evaporative cooling iec uses a hyper efficient counter flow heat exchanger to produce 100 fresh cool outside air with no added moisture.

Indirect evaporative cooling heat exchanger.

The main difference with an indirect system is that a heat exchanger is used to cool the air supplied to the living space. Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate. Nowadays there are several ongoing researches on indirect evaporative coolers investigating through numerical and experimental approaches the effect on system performance of heat exchanger material and geometry of airflows layout of water distribution configuration and of inlet air and water conditions. The cooled moist air from the direct evaporative cooling process never comes in direct contact with the conditioned supply air.

Interest has also raised in. Heatex cross flow heat exchangers can answer all these requirements while providing up to 80 exchanger efficiency. Our cross flow heat exchangers coupled with evaporative cooling technology provide an efficient low cost and environmentally friendly alternative to traditional methods of cooling data center electronics. 2 the fresh cold air produced by iec can be equivalent to that produced by refrigerated system with temperature that approach the ambient dew point temperature.
