摘要
Abstract
This study conducts numerical simulation research on the changes in parameters such as average air temperature,relative humidity,and air enthalpy during permanent operation of the ventilation tunnel,safety tunnel,and traffic tunnel of Hebei Shangyi Pumped Storage Power Station.The calculation results indicate that outdoor fresh air undergoes significant changes in temperature and relative humidity before entering underground buildings.The air temperatures at the ends of the ventilation and safety tunnels in summer reach 13.6 ℃,respectively.After outdoor fresh air passes through the walls of the tunnel,the summer temperature drops to 14.6 ℃.The temperature at the end of the traffic tunnel in summer is close to the deep ground temperature,and the temperature drop in summer is 18 ℃.Therefore,the control effect of the ventilation tunnel,safety tunnel,and traffic tunnel enclosure structure on outdoor fresh air temperature cannot be ignored.The relative humidity at the end of the ventilation tunnel,safety tunnel,and traffic tunnel reached 100％in summer.The relative humidity at the ends of both chambers reached saturation in summer,indicating the need to add dehumidification or auxiliary heat source facilities to alleviate the adverse effects of high relative humidity on the underground powerhouse.关键词
