Indirect evaporative cooling heat exchanger.

The evaporative cooling cycle occurs in the 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. 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. 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 closed circuit is a cooling process that uses direct evaporative cooling in addition to some heat exchanger to transfer the cool energy to the supply air. 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. Indirect evaporative cooling works on the same principle as direct evaporative cooling lowering air temperature by causing water to evaporate. Heatex cross flow heat exchangers can answer all these requirements while providing up to 80 exchanger efficiency.
