HFC-227ea(FM200) fire suppression system
HFC-227ea is also called FM200
1 Physical properties of gas fire extinguishing agent(HFC227ea fire extinguishing agent) physical properties:
HFC227ea fire extinguishing system can be mainly used in places such as: Personnel resident area, warehouse for storage expensive equipment and important data file place, electrical equipment the place need no conductive fire extinguishing agent, not allowed to cause water damage or some places not allowed be contaminated sites. The computer rooms, electrical data processing & storage center, communication equipments site, telecom telephone exchange room, clean room, programming room, emergency power supply facilities, library, museum and art gallery, expensive medical facilities etc...
2 system design principles
The HFC227ea gas fire extinguishing system adopt total flooding protection.
Because the area and equipment is important which protected by HFC227ea gas fire extinguishing system. It also put forward higher requirements on fire protection engineering technology. The technical solution of HFC227ea has reflected the advanced nature. Its technical requirements and conditions are mainly embodied in:
A. The main function of the system of HFC-227ea: Real time monitoring the protection zone in normal condition. It can automatically alarm in fire accidents, and start the automatic fire extinguishing device according to the control mode under preset data. To release gas fire extinguishing agent, quickly put out the fire in protection district, which in order to protect the equipment running in normal in this zone.
B. The system is composed of two parts such as gas fire-fighting equipment and control system (fire alarm and linkage control equipment).
C. Control system with automatic control mode, manual control mode and emergency manual control mode;
D. Each protection zone can sent fault signal, gas release signal, automatic / manual state signal to the fire alarm system
2.1 The basic parameters of system
Fire put out methods: Total flooding fire
System startup mode: Automatic, manual, mechanical emergency operation
Design temperature: -20 ° C ~55 ° C
Discharging time of gas agent: Not more than 10s
