According to Shanghai Fire Bureau of fire statistics in recent years, the number of residential fires accounted for the proportion of the total number of fires has been high, generally above 40%. Therefore, the enhanced capacity of residential buildings against fire in order to reduce the losses caused by fire is necessary. National Fire Protection Association in 1975 on the development of a residential sprinkler system design criteria. Some foreign manufacturers have started developing and producing a special residential sprinkler head manufacturers in China have carried out the production of such nozzles.

Therefore, the residential sprinkler water supply duration and the area of the sprinkler system than the average lower.

3 design parameters 3.1 nozzle choice Residential sprinkler system water as a simple way, as well as the system provides water reach the size of conventional systems, it quickly turned heads and reduce the amount of water spray sprinkler system residential sprinkler system is designed to be achieved.

3.2 Design of active area

Existing national standards, "Automatic sprinkler system design" on a system with fast response sprinkler system did not propose to reduce the role of area specific provisions. In the actual project residential or other areas would be separated into several separate small fire, the active area of computing can be a separate room for fire safety design, the role of an area the size of the general area of maximum design basis for the separation.

3.3 times the water supply system Small residential settings

fast response sprinklers for residential fire that occurred early general can quickly extinguished. From the sprinkler system Automatic fire extinguishing The case, can be found in general within the fire fighting time 10min.

3.4 nozzle pressure of work and installation requirements

Residential sprinkler working pressure is generally not less than 0.05mpa, a minimum working pressure not less than 0.025mpa. Installation of sprinkler spacing should not exceed 2.4m. Water density residential sprinkler systems desirable 6l / (min? M2), the installation of sprinkler spacing must meet the requirements of water density.

4 Notes

Residential sprinkler system in Shanghai after a period of time after installation, fire inspection also found some problems. residential sprinkler system is a simple sprinkler system,
