Measures Of Elevator Running And Ventilation Epidemic Prevention

In order to avoid the transmission of virus through elevator antechamber in high rise residential buildings and prevent the cross-infection in community resident，bassed on the theoy of piston effect produced by the movement of elevator car，its influence on the pressure difference of elevator well and elevator antechamber is analyzed.Combining with the principle of mechanical ventilation，through reasonable design of the ventilation system，it ensures that the air is not interdiffusion in elevator well，car and antechamber.
