Laboratory Evaluation of the Seeley Climate Wizard Indirect Evaporative Cooler

Testing was conducted to evaluate the performance of an early production model of the Climate Wizard indirect evaporative cooler from Seeley International.  Indirect evaporative coolers make use of the inexpensive cooling derived from the evaporation of water, but do not add moisture to the outside air supplied to the conditioned space.

A test condition matrix was established to evaluate system performance over a range of environmental conditions, which would capture the cooling design conditions for several locations in the PG&E service territory.  Other tests were conducted to determine its sensitivity to supply air external resistance and fan speed.
