Summary

To study the heat transfer performances of the water film outside of evaporative condenser tubes, the experimental apparatus were built up. In this paper, the effects of the spray density and the face air velocity on the heat transfer coefficient were investigated under various experimental conditions. The experimental results showed that when spray density was 0.061 kg/(m.s) and face air velocity was 4.9 m/s, the heat transfer performances of the evaporative condenser came to optimum state. Further more, the classical correlation equation for the heat transfer coefficient of the water film was obtained through regression analysis of the experimental data. In addition, the influence of the face air velocity on the heat transfer coefficient was very important which was never considered.
