在开发的计算机程序中采用默克尔法、波普法和经验方程来预测自然通风湿式冷却塔 (NDWCT) 的蒸发损失。实验结果对这三个模型进行了验证。洛阳某300MW电厂NDWCT的计算结果表明，无论是Merkel法还是经验方程都无法像Poppe法那样进行准确的蒸发损失预测。采用NDWCT和自然通风混合冷却塔（NDHCT）的电厂的年用水量和经济效益是根据每小时的天气情况计算的。结果表明，用 NDHCT 替代 NDWCT，电厂可节水 95% 以上，但每年损失 15,464,306 美元。
The Merkel method, the Poppe approach, and an empirical equation are employed in the developed computer program to predict the evaporation loss for the natural draft wet cooling tower (NDWCT). All the three models are validated with the experimental results. The calculation results in the NDWCT of a 300-MW power plant in Luoyang show that both the Merkel method and the empirical equation could not make the accurate evaporation loss prediction as the Poppe approach does. The annual water consumption and economic benefits for the power plant employed with the NDWCT and the natural draft hybrid cooling tower (NDHCT) are calculated by using the hourly weather condition. The results show that the power plant would save more than 95% of water but lose US$15,464,306 per year by replacing the NDWCT with the NDHCT.
