Abstract:

This paper explains how Indirect Evaporative Cooling (IEC) uses water as a refrigerant. This water refrigerant may be seen as part of the rain cycle, whereby the environment (not a heat pump) returns water as the refrigerant to the system after re-condensing it. Since the rain cycle is largely driven by the solar source, so then is IEC. Indirect Evaporative Cooling (IEC) may be efficiently produced by wetting the room exhaust stream plates of an airto-air heat exchanger so that water evaporation caused by the cool, relatively dry exhaust air effectively cools the incoming ventilation air stream as it passes through the other (supply) side of the heat exchanger. In practice, very high Coefficients of Performance (COP's) have been recorded with IECs operating in hot, dry climates. These systems perform with low energy consumption requiring energy only to power fans and small water pumps. Surprisingly, a humid climate also yields a very high COP. Copyright © 2010 by ASME.
