AbstractFor an underground hydropower stations, understanding the heat and mass transfer behaviour of outdoor air flowing through ventilation tunnel can help improve the design of ventilation systems and reduce energy consumption. The aim of this paper is to investigate the influences of summer outdoor meteorological parameters on the tandem ventilation process and the designed parameter requirements in the main plant.
