초록

NFSC103의 배관스케줄방식으로 설계하는 경우, 작동면적 내의 헤드 약 50%가 최소요구량에 못미치는 문제점을 해결하기 위하여 NFSC103과 NFPA13의 배관스케줄방식을 비교, 분석하였으며 NFSC103의 유량부족 문제를 해결할 수 있는 새로운 방법을 제시하였다. 각 헤드에서의 소화수방출량을 기존의 80 L/min의 150%인 120 L/min으로 하면 수리계산한 값을 상회하여 모든 헤드에서 최소기준값인 1 bar, 80 L/min을 충족하게 된다. 이는 누구나 쉽게 배관스케줄방식으로 설계할 수 있으며 설계면적 내의 모든 헤드가 최소요구량을 충족하는 최적의 방법이다.

Design by means of the pipe schedule sprinkler system of NFSC 103 results in insufficient pressure and flow rate about 50% sprinklers of operating area. In order to solve the lack of pressure and flow rate, This paper compare and analyzed NFSC 103, National Fire Safety Code of Sprinkler System, with NFPA 13, Standard for the Installation of Sprinkler Systems, and suggested an alternative proposal. Changing the flow rate of each sprinkler from existing 80 L/min to 120 L/min, All of the operating sprinklers are fulfilled the minimum demands on 80 L/min and 1 bar. It is easy for everyone to design of the pipe schedule sprinkler system and it is optimum method that all sprinklers in design area are satisfied with minimum criteria.
