摘要
本文以某大型能源枢纽主控制室为原型,建立了该主控制室大惯性热阱系统的物理模型和数学模型,分析出事故条件下影响热阱放热特性的主要因素有肋片布置形式、热阱初始温度、热阱蓄热面积、室内热扰强度等。通过多工况数值模拟,研究各影响因素对主控制室72 h温度控制及主控制室安全性能的影响。
This paper constructed a physical model and mathematical model of the passive system with large inertia in the control room of a large-scale energy station for a practical engineering. Then it was identified that the main influence factors for the discharge character of the heat sink system, included fin distribution, the initial temperature of heat sink system,the area of heat sink system,and internal heat interference intensity. Finally,these influence factors＇ effect on 72-h temperature control in the main control room and the safety performance of the master control room was researched through numerical simulation of multiple loading conditions.
