Summary

THERMAL CHARACTERISTICS OF HEATING TOWERS FOR AIR-SOURCE HEAT PUMPS ARE STUDIED IN TERMS OF THE OVERALL ENTHALPY-TRANSFER COEFFICIENT. FIRST, THE METHOD OF COUNTERFLOW CALCULATION IS PRESENTED, TAKING PHYSICAL PROPERTIES OF ETHYLENE GLYCOL SOLUTIONS INTO ACCOUNT. NEXT, BOTH COOLING-TOWER AND HEATING-TOWER EXPERIMENTS ARE CARRIED OUT IN A SMALL, INDUCED-DRAFT, COUNTERFLOW TOWER PACKED WITH TUBES OF A STAGGERED ARRANGEMENT, USING WATER AND COMMERCIAL ETHYLENE GLYCOL SOLUTIONS. THE COEFFICIENT MEASURED IN THE HEATING-TOWER EXPERIMENT SHOWS A TREND SIMILAR TO THAT IN THE COOLING-TOWER EXPERIMENT.
