The energy-saving potential of precooling incoming outdoor air by indirect evaporative cooling.

Author(s) : CHEN P., QIN H., HUANG Y. J., WU H., BLUMSTEIN C.

Summary

The paper investigates the energy-saving potential of using indirect evaporative coolers to precool incoming outdoor air as the first stage of a standard cooling system. For dry and moderately humid locations, either exhaust room air or outdoor air can be used as the secondary air to the indirect evaporative precooler with similar energy savings. For humid locations, the use of exhaust room air is recommended. For locations with short cooling seasons, the use of indirect evaporative coolers for precooling may not be worthwhile. The paper also gives some simplified indices for easily predicting the precooling capacity, energy savings, and water consumption of an indirect evaporative precooler.
