METHOD OF METRO STATION VENTILATION

摘要

FIELD: process engineering. ^ SUBSTANCE: proposed method comprises air flows displacement by moving electric train and feed fresh air to passenger platform by varying air density on said platform. Note here that train is provided with fluid air to be released in air space of metro station equipped with vent shaft. Air with higher density displaces warm dirt air into station vent shaft to replace it by fresh cold air. ^ EFFECT: fresh air feed in whatever season.
