| 摘 要： | 采用风洞试验方法研究下垂型和直立型CMSA喷头的动态热性能,分析总结CMSA喷头的导热系数和响应时间指数的特点。导热系数由等速率升温试验计算。可以考虑采用ESFR喷头的计算公式计算CMSA喷头的导热系数和响应时间指数,采用普通洒水喷头的分类将其归入标准响应喷头的范围。

| Abstract: | The dynamic thermal properties of sag type CMSA sprinklers and upright CMSA sprinklers were discussed by wind tunnel test methods.The thermal conductivity was calculated by warming test of equal rate,and RTI of CMSA sprinklers were analyzed.It was suggested that the calculation of thermal conductivity and RTI of CMSA sprinklers can be completed by using the ESFR sprinkler formula.The CMSA sprinklers belong to the standard response sprinklers according to the classification of ordinary sprinklers. |
