Abstract:The exhaust system after gas fire extinguishing shall be started normally to ensure that all extinguishing agents and exhaust gases in the protection area are discharged,and personnel enter the protection area for operation and maintenance after the disaster. Combined with 4 typical working conditions,this paper discusses the design of power distribution and control system of exhaust system after gas fire extinguishing,as well as the coordination of electrical with HVAC,water,architecture and other disciplines.
Key words:gas fire extinguishing;exhaust system after disaster;power distribution and control;protected area;electric fire damper;closed valve;automatic fire alarm system;professional cooperation
