摘　　要：在深入分析循环冷却水进水温度与凝汽器压力之间关系的基础上,提出了定量分析计算的方法。通过实例计算分析得出结论,在循环冷却水进水温度波动范围较小时,采用简化算法完全可以满足工程应用,而当循环冷却水进水温度波动范围较大时,应考虑凝汽器热负荷变化对凝汽器压力的影响,此时宜采用迭代算法。Based on the analysis of the relationship between circulating cooling water and condenser pressure,a method of quantitative calculation is presented.Trough computation and analysis by examples we can draw a conclusion,when the fluctuation range of inlet temperature of circulating cooling water is small,the simplified algorithm can fully meet the engineering application.When the fluctuation range of inlet temperature of circulating cooling water is wide,the influence of the condenser heat load changed should be considered.At this time,iterative calculation should be adopted.
