| 摘 要： | 采用焓差法建立了自然通风冷却塔出口水温的热力计算模型，并把凝汽器和冷却塔作为一个整体综合研究和分析了冷却塔出口水温的各种影响因素及其影响规律．结果表明：冷却水量、填料断面风速、凝汽器蒸汽负荷以及环境空气的相对湿度均对冷却塔的进口和出口水温有明显影响，且上述因素对进口水温的影响大于对出口水温的影响．

| Abstract: | Using enthalpy difference method, a calculation model for outlet water temperature of a natural draft cooling tower was set up, with which factors influencing the outlet water temperature were studied by integrating the condenser and the cooling tower as a whole. Results show that both the inlet and outlet water temperature are influenced by cooling water flow, air velocity at packing section, steam load of con denser and relative humidity of air, and the effect on inlet water temperature is greater than that on outlet water temperature. |
