| 摘 要： | 阐述了蒸发式冷凝器选型的常用方法及一般步骤。依据国内外推荐的经验数据计算得出．蒸发式冷凝器的单位排热量耗功分别约为21．86W/kW、11，12W／kW．前者能耗约为后者能耗的2倍。同时提出了蒸发式冷凝器选型的能耗核算新公式，并通过实例分析了该公式的应用。计算发现．选用不同品牌的蒸发式冷凝器．运行能耗差异很大。能耗核算新公式可以方便地比较不同品牌蒸发式冷凝器的运行能耗．单位排热量耗功驴值最小者即为运行能耗最低者。

| Abstract: | Traditional methods and steps used in the selection of evaporative condensers are introduced. Calculation results based on empirical data recommended at home and abroad show a great difference in energy consumption. The energy consumption of evaporative condensers is approximately 21.86 W/kW for the former, but 11.12 W/kW for the latter. A formula to audit the energy consumption of evaporative condensers is proposed, and the application of the formula is tested to practical products. The results indicate that the energy consumptions of different brands of evaporative condensers are quite different. The proposed formula allows operating energy consumptions of evaporative condensers to be compared with the minimum energy indicated when the value of Ф in the formula is a minimum. |
