FACTORY VENTILATING METHOD AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a factory ventilating method and its device for ventilating the whole room of a factory without diffusing contaminants into the room while using a local ventilator (an exhaust or a push-pull ventilator) for accurately trapping and exhausting the contaminants generated in the factory with production activity. SOLUTION: The local ventilator 2 is used for exhausting the contaminants generated in part of the factory and supplying air from a lower side 7 into the whole factory. A rising air flow produced by heat build-up equipment 3 installed in the factory is utilized to cause substitutional ventilation for exhausting air from an exhaust port 8 in a ceiling.
