MIVE- / elevator ventilation system


Elevator’s upward/downward motion-induced airflow can be directed by check valve to create constant passive decontamination dilution ventilation for health. While elevator moving, both upward/downward flow air will be pumped into walled pipes to generate plugflow to push a floating ball plugging up a hollow stopper and the air will be directed through middle inlet into the car, meanwhile, exhausted air in car will be pulled away from upper/under outlet by outside airflow due to Venturi tube effect. MIVE can be a constant passive ventilation system as well as a public health measure of protection against influenza.
