摘要

在工程应用条件下，对带有三维管的垂直管下流式复合蒸发冷却塔（VTD-CECT）的热性能进行了模拟。分析了不同环境空气条件、不同热水入口温度和不同喷雾密度对VTD-CECT冷却性能的影响。对实验样机进行了性能测试，并与仿真值进行了对比，结果表明所建立的VTD-CECT热性能预测模型具有较好的预测效果。分析了填料对提高蒸发冷却塔冷却能力的影响，结果表明，在50%的冷却气流通过填料的情况下，在可调的试验条件范围内，可提高VTD-CECT的冷却能力31.7% ~ 40.8%，降低喷淋水温0.94 ~ 2.79℃，且减少金属使用量显著。提出了一种评价闭式冷却塔制冷量的方法。本研究可为VTD-CECT的工程应用提供参考。

Simulation and experimental verification of cooling thermal performance of vertical tube downflow composite evaporative cooling tower

The thermal performance of a vertical tube downflow composite evaporative cooling tower(VTD-CECT) with three-dimensional tubes was simulated under engineering application conditions. The effects of different ambient air conditions, different hot water inlet temperatures, and different spray densities on the cooling performance of VTD-CECT were analyzed. The performance test of the experimental prototype was carried out and compared with the simulated values, and the results show that the established VTD-CECT thermal performance prediction model has a good prediction effect. Analyzed the impact of packing to enhance the cooling capacity of evaporative cooling tower, the results show that in the case of 50 % of the cooling airflow through the packing, in the range of adjustable test conditions can enhance the cooling capacity of the VTD-CECT 31.7 % ∼ 40.8 %, reduce the spray water temperature of 0.94 ∼ 2.79 °C, and the reduction in metal usage is significant. A methodology for evaluating the cooling capacity of closed cooling towers is proposed. This study can provide a reference for the engineering application of the VTD-CECT.

期刊介绍： The International Journal of Refrigeration is published for the International Institute of Refrigeration (IIR) by Elsevier. It is essential reading for all those wishing to keep abreast of research and industrial news in refrigeration, air conditioning and associated fields. This is particularly important in these times of rapid introduction of alternative refrigerants and the emergence of new technology. The journal has published special issues on alternative refrigerants and novel topics in the field of boiling, condensation, heat pumps, food refrigeration, carbon dioxide, ammonia, hydrocarbons, magnetic refrigeration at room temperature, sorptive cooling, phase change materials and slurries, ejector technology, compressors, and solar cooling. As well as original research papers the International Journal of Refrigeration also includes review articles, papers presented at IIR conferences, short reports and letters describing preliminary results and experimental details, and letters to the Editor on recent areas of discussion and controversy. Other features include forthcoming events, conference reports and book reviews. Papers are published in either English or French with the IIR news section in both languages.
