Summary

A METHOD IS PROPOSED FOR PREDICTING THE VARIATIONS OF AIR AND WATER TEMPERATURES AND OF AIR HUMIDITY IN A PACKED BED COUNTERFLOW TYPE OF COOLING TOWER SUBJECTED TO A THERMAL DISTURBANCE. HEAT INPUT-RESPONSE MEASUREMENTS ARE CARRIED OUT BY IMPOSING THERMAL DISTURBANCES ON INLET WATER AND INLE THE AIR-FILM AND WATER-FILM HEAT TRANSFER COEFFICIENTS ARE ESTIMATED BY FITTING IN THE TIME DOMAIN THE MEASURED OUTPUT TEMPERATURE/HUMIDITY VARIATIONS TO THOSE PREDICTED.
