摘要:
通过对同一个自动喷水灭火系统,分别采用特性系数+当量长度法、特性系数+百分数法和估算法进行设计流量、压力计算、比较分析,结果表明:采用特性系数+当量长度法计算的结果最接近实际工况;特性系数+百分数法的计算结果略小于特性系数+当量长度法;估算法计算值最小,不能满足设计规范的要求,提出对于严重危险和仓库危险级场所,必须采用特性系数+当量长度法进行水力计算,对于轻中危险级场所,建议采用特性系数+百分数法计算。
Abstract:
The article uses characteristic coefficients + equivalent length method, characteristic coefficients + percentage method and estimation method to calculate the design flow and pressure in the same automatic sprinkler system respectively. The results indicate show that result calculated by the characteristic coefficients + equivalent length method is closest to the actual working condition; the result by characteristic coefficients + percentage method of calculation is slightly smaller than that by characteristic coefficients + equivalent length method; the result by estimation method is smallest and can not meet the design requirements. The characteristic coefficients + equivalent length method must be used for serious dangerous and warehouse risk grade places. The characteristic coefficients + percentage method are recommended at light or intermediate dangerous places.
