    an experimental study was conducted to investigate the effect of a tube row, a fin pitch and an inlet humidity on air-side heat and mass transfer performance of louvered fin-tube heat exchangers under wet condition. experimental conditions were varied by three fin pitches, two rows, and two inlet relative humidities. from the experimental results, it was found that the heat transfer performance decreased and the friction increased with the decrease of a fin pitch, for 2 row heat exchanger. the effect of a fin pitch on heat transfer performance was negligible with 3 row heat exchanger. the change in a relative humidity was not affected heat transfer and friction. however, the mass transfer performance was slightly decreased with the increase of a relative humidity and with the decrease of a fin pitch. the mass transfer performance decreased with the decrease of a fin pitch. the mass transfer performance of the louvered fin-and-tube heat exchanger was different according to the number of a tube row.
