Effects of evaporation water flow rate on the cooling performance of an indirect evaporative cooler.

Author(s) : CHOO H. S., LEE K. S., LEE D. Y.

Summary

In evaporative cooling applications, the evaporation water is supplied usually sufficiently larger than the amount evaporated to enlarge contact surface between the water and the air. Especially in indirect evaporative coolers, however, if the evaporation water flow rate is excessively large, the evaporative cooling effect is not used for heat absorption from the hot fluid but spent to the sensible cooling of the evaporation water itself. This would result in a decrease in the cooling performance of the indirect evaporative cooler. In the study, the effects of the evaporation water flow rate on the cooling performance are investigated theoretically. The results show that the decrease in the cooling effectiveness is substantial even for a small flow rate of the evaporation water and the relative decrease is more serious for a high performance evaporative cooler.
