摘　　要：GB 50974—2014《消防给水及消火栓系统技术规范》实施后设置稳压泵的临时高压消防给水系统为防止稳压泵频繁启停而采用的气压水罐,与GB 50974—2014实施前临时高压消防给水系统的高位水箱设置高度不能满足最不利处水灭火设施静压要求而设置的稳压气压水罐,虽同为消防用气压水罐,同有稳压作用,但其设计理念,使用功能有很大不同,不能混为一谈,在设计上更不能套用。详细介绍了气压水罐的设计理念和计算方法,以及由此确定消火栓系统的竖向分区。After the implementation of GB 50974-2014 Technical Code for Fire Protection Water Supply and Hydrant Systems, air pressure tank is adopted in temporary high pressure fire protection water supply system to prevent pressure maintenance pumps from frequent starts and stops. It is different from the stabilized air pressure water tank set to meet the requirement that the height setting of head water tank of fire protection water supply system of temporary high pressure shall conform the static pressure requirement of fire-extinguishing installation at the worst place set before the implementation of GB 50974-2014 in aspects of design philosophy and using function. Although both are gas pressure water tanks specialized for fire protection and both have the function of pressure maintenance, they can neither be confused with each other, nor be applied indiscriminately in design. The design philosophy and computing method of air pressure water tank as well as the confirmation of vertical compartment of hydrant systems were introduced in detail.
