摘要
对GB 50015—2003《建筑给水排水设计规范》(2009年版)[1]闭式膨胀罐容积计算公式中最大允许压力(绝对压力)参数P2取值进行分析探讨,通过推导闭式膨胀罐容积的计算公式及分析工程实例,得出了闭式膨胀罐参数P2值的正确计算方法。
The maximum allowable pressure( absolute pressure) parameter P2 value for closed expansion tank volume calculation formula in GB 50015—2003《Code for design of building water supply and drainage》( 2009) was analyzed and discussed. By deducing the calculation formula for the closed expansion tank volume and through engineering example,the correct calculation method for P2 value within the expansion tank was given.
