随着核电站装机容量的迅速增加,如何减少核电的用电量、节约成本,已经成为人们普遍关注的问题。针对海南某地区核电站对室内温湿度及送风温湿度的要求,分别计算出蒸发冷却、机械制冷的冷量、风量、能效比(EER)。并利用海南某地区的逐时气象参数和焓湿图分析指出开启蒸发冷却、机械制冷的小时数及占全年运行时间的百分比。得出了蒸发冷却在以显热为主的核电领域具有大量的应用前景。
With the rapid increase of nuclear power plant installed capacity, how to reduce the electricity consumption of nuclear power and save costs has become a common concern. Aiming at the requirements of indoor temperature and humidity and air temperature and humidity of nuclear power stations in a certain area in Hainan, the EER of evaporative cooling and mechanical cooling are respectively calculated. The hourly meteorological parameters and the psychrometric chart of an area in Hainan were used to analyze the hours of opening of evaporative cooling and mechanical refrigeration and the percentage of running hours in the whole year. It is concluded that evaporative cooling has a great deal of application prospects in the field of nuclear power mainly with sensible heat.
