摘　　要：本文以核电站的电气间通风设计为例,介绍了核电站电气间的设计原则,并结合了项目地点的气象参数条件,进行了全新风(新风未冷却处理)、室外新风蒸发冷却、室外新风加室内风循环冷却三种方案的数值模拟计算。结果表明,室外新风加室内风循环冷却方案相比全新风(新风未冷却处理)方案,风量减少51%,相比外新风蒸发冷却方案,未造成空调冷负荷的浪费,且可满足房间温度要求。Taking the ventilation design of the electrical room of a nuclear power plant as an example, the design principles of the electrical room of the nuclear power plant are introduced, and the numerical values of three schemes of fresh air(fresh air without cooling), outdoor fresh air evaporative cooling, and outdoor fresh air heating and indoor air circulation cooling are carried out in combination with the meteorological parameters of the project site. Compared with the fresh air(fresh air without cooling) scheme, the outdoor fresh air plus indoor air circulation cooling scheme reduces the air volume by 51%. Compared with the outdoor fresh air evaporative cooling scheme, it will not cause waste of air-conditioning cooling load and can meet the room temperature requirements.
