Abstract: Energy consumption of ventilation and air conditioning system in subway operating energy consumption accounts for 30%~40%of total energy consumption. The soil around the subway station is rich, which provides good conditions for the use of the tunnel air system. This paper establish a model of metro station tunnel air system and use FLUENT simulation analysis underground air temperature of short-term conditions in the most typical summer hot weather, calculation and analysis of tunnel ventilation system of the heat exchange efficiency and cooling efficiency. The results show that the air temperature in the subway station is satisfied with the standard of air temperature, and the energy saving of the subway station is confirmed.
