一般住宅用簡易スプリンクラー消火装置の開発に関する研究

摘要

This paper is concerned with experimental study on what is the minimum requirements for design of alow cost residential sprinkler system and how effect this system will be for fire suppression. At first, several basic experiments at different water pressure conditions are carried out to investigate the minimum requirements for the fire suppression. Next, fire extinguishing tests on a residential sprinkler experimental system have been taken place at a real residential house. These experimental results have pointed out several important facts. The additional water tank with electric pump will be required if the pressure at the sprinkler head is lower than 0.1 MPa. Further, if the output pressure at the head is lower than 0.02 MPa or the flow is less than 20 L/min, the fire extinguishing will be probably failed. On the other hand, if the output pressure at the head is higher than 0.1 MPa and the flow is larger than 50 L/min, the initial fire extinguishing will be succeeded. Finally, a compact residential sprinkler fire extinguishing system has been designed based the experimental results.%総務省消防庁によると.H21(2009)年における全国の火災件数は51,139件あり，そのうち建物火災は28,372件で55.5%を占めている.建物火災の中で住宅火災は16,313件で.建物火災の57.5%にのぼる.また，住宅火災の件数比率を見ると，一般住宅が10,531件(64.6%),共同住宅が5,025件(30.8%),併用住宅が757件(4.6%)と，一般住宅火災が頻発していることがわかる.
