Air distribution in underground main workshop of Langya Mountain Hydroelectric Power Station

Based on the experimental research on the thermal state simulation model of the station, mainly focus on the different manners of vault air supply, such as different quantity, velocity and temperature of air supply and different quantity of air outlet, obtains a great deal of experimental data. Compared with the successfully used vault symmetrical air supply manner in such famous great hydroelectric power stations as Ertan, Xiaowan and Longtan, with the particularity of equipment arrangement in this project, develops the vault asymmetrical air supply manner suitable for the power station.
