核电站常规岛蒸发冷却与机械制冷对比分析

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。

Contrastive Analysis Evaporative Air-conditioning to Mechanical Cooling on the Application of Conventional Island Nuclear Power Plant

With the increasing in the capacity installed of nuclear power plant, how to reduce the use of nuclear electrical and save the cost have paid attention to people. At the present, nuclear power plant is constructed in Hainan. The temperature and humidity of indoor and supply air temperature need to meet the requirement of equipment running. Then respectively calculating the cooling volume of evaporative air conditioning, the cooling volume of mechanical cooling, air volume, energy efficiency ration. By means of analysis weather parameters hourly in Hainan and enthalpy wet chart, it shows that the time of running evaporative air conditioning, mechanical cooling the percent of running yearly. At the same time, evaporative air conditioning have a lot of sensible heat that was widely used in nuclear power plants.
