HVAC system design for underground plant of a hydropower station in hot and humid region
摘要：
该水电站位于赤道线上的热带雨林气候区，全年平均相对湿度为90%。介绍了该水电站工程的设计依据、工程概况及设计中遇到的困难。在方案阶段，实测得到的温湿度数据与预估方法的计算值基本接近。给出了设备照明发热量的计算和通风气流组织设计。阐述了所采取的技术措施：温度湿度独立控制技术、空调水大温差设计、气流组织保证措施、非常规压水发电工况下的环境影响分析、通风排烟措施。
Abstract：
The hydropower station is located in tropical rainforest climate zone of the equator line with the annual mean relative humidity of 90 percent. Presents the design references, project overview and difficulties encountered. During design scheme stage, the measurement data of temperature and humidity are close to the calculated results by estimated method. Presents the calculation of heat release of devices and lighting, and the design of air distribution. Expounds the adopted technical measures, including temperature and humidity independent control, large temperature difference water system, safeguard measures of air distribution, environmental influence analysis under the condition of non-conventional power generation with pressurized water, ventilation and smoke exhaust measures.
Keywords:hydropower station, underground plant, ventilation and air conditioning, hot and humid region, temperature and humidity independent control, air distribution
