Abstract

To examine the effects of heat resistance in the liquid phase on the characteristics of heat and mass transfer in packed towers, a small packed tower was built and operated. The experimental data obtained were analyzed. Heat resistance in the liquid phase measured in cooling tower and heating tower experiments using water was low, and the effects of heat resistance in the liquid phase were small. In a heating tower using ethylene glycol, however, the ratio of heat resistance in the liquid phase to total heat resistance was higher; 0.4 to 0.45. Hence, in design calculation for heating towers using ethylene glycol, heat resistance in the liquid phase must be taken into account.
