The air-side heat transfer and friction characteristics of one-row and two-row wavy fin-and-tube heat exchanger under dehumidifying condition were studied experimentally.The results showed that the heat transfer factor was strongly related to the number of rows
and the heat transfer factor of tworow heat exchanger was 60% greater than that of onerow one.The effect of the number of rows on the friction factors could be negligible.Fin efficiency increased as inlet water temperature decreased
while it decreased as wind velocity increased.The experimental value of heat transfer factor was 30% lower than that predicted by the Pirompugd correlation .
