Abstract

PURPOSE: To make a ventilating and air-conditioning system compact, by circulating air in a central control room via an emergency filter and a fan at the time of emergency, and introducing open air from an isolating valve after purification of the open air.
CONSTITUTION: Open air introduced from an open-air inlet port 6 is carried via an isolating valve 4 and an ordinary filter train 5 into a central control room 1 by means of a fan 3 and discharged to the outside from an outlet port 8. However, a portion of air is recirculated via a recirculating pipe 2. A portion downstreams of fan 3 and a portion upstrems of an exhaust fan 7 are connected to each other by an emergency recirculating pipe 15 having an emergency filter 10 and a suction fan. Further, a suction pipe 16 having an isolating valve 13 and an intake port 11 is connected to an upstream portion of the emergency filter 10.
