摘　　要：自2014年10月1日起实施的《消防给水及消火栓系统技术规范》(GB 50974—2014),其中消防给水系统中与稳压泵配套的气压水罐的设计选型计算有些改变。目前建筑给水排水工程施工图设计文件(设计图纸)中,对于气压水罐的相关设计参数的表达,普遍存在不规范、不统一、概念模糊和表达深度欠缺的现象。鉴于此,对消防给水及生活给水系统中气压水罐的设计选型设计进行了探讨,以供参考。The Technical Code for Fire Protection Water Supply and Fire Hydrant Systems （GB 50974 -2014） has been implemented since October 1, 2014, in which there are some changes in calcu- lation of design and type selection of pneumatic water tank matched with pressure maintenance pump in the fire water supply system. The expression of the design parameters of pneumatic water tank is non- standardized, non-unified, fuzzy and lack of depth in construction drawings design documents of building water supply and drainage projects. In view of this, the calculation of design and type selection of pneu- matic water tank in the fire and domestic water supply systems was discussed for reference.
