Abstract

PURPOSE:To make self-ventilation possible, by providing an air outlet for fresh air around an inlet of an exhaust hood so that fresh air is blown off to aurround a local region where ventilation is requried and to supply the fresh air there. CONSTITUTION:The air outlet 5 having an air flow adjuster 7 is arranged around the inlet 2 of the exhaust hood 1, and an air supply apparatus 8 for blowing off fresh air is arranged. The air supply apparatus 8 consists of a fresh air intake 9, a pressure fan 10 and a concrete chamber 11, and a hood chamber 12 is arranged in a room. The fresh air taken in by the pressure fan 10 is introduced into the chamber 11, is sent to the hood chamber 12, and is blown off from the air outlet 5 to surround the local section S isolatedly. Accordingly, the exhaustion and air supply are effected exclusively at the local section S, so that local ventilation becomes possible without stirring up the ambient air.
