Indirect Evaporative Cooling Heat Exchanger

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 heat exchanger. 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. Heatex cross flow heat exchangers can answer all these requirements while providing up to 80 exchanger efficiency. Interest has also raised in. 1 indirect evaporative cooling iec uses a hyper efficient counter flow heat exchanger to produce 100 fresh cool outside air with no added moisture.

The main difference with an indirect system is that a heat exchanger is used to cool the air supplied to the living space. The evaporative cooling cycle occurs in the heat exchanger. 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. The indirect evaporative section also incorporates a scavenger fan to exhaust air through the pipes a water distribution system which includes a water pump and spray nozzles to provide a uniform distribution over the entire heat exchanger and a filter section to clean and maintain incoming air into the system.
