VENTILATION IN THE METRO

L'ATMOSPHERE DU METRO

The Paris Transport Authority, which conveys 4 million passengers per day on lines most of which are underground, has set 4 objectives for air-conditioning its installations. In summer, the temperature should not be more than 5 deg C higher than outside temperatures, air in tunnels should be renewed 4 times every hour, the speed of air currents must not exceed 5 m/s, and humidity must remain between 30 and 70 percent. Better ventilation systems will be installed, as well as air vents, equipment for air renewal and for ventilation in vehicles; biological climatic, thermal and aerodynamic studies will be carried out with the view to energy retrieval.
