摘　　要：消防气压给水设备的总容积是由消防系统最高动水压与静水压的比值、系统的水净膨胀容积决定的。它的最小总容积完全取决于消防系统本身,包括:管网布置、喷头安装方式、设计温度差、温度变化的速度和系统水的漏水率。如果气压给水设备不仅用作消防系统的定压,而且兼有消防水箱的功能,则总容积应取二者当中较大值。The total eubage of the pressurized type water supply unit depends on the ratio of maximum dynamic and static water pressure of the fire protection system as well as the net dilatation cubage of the water in the system. Its minimum total cubage completely depends on the system itself, which includes： allocation of the pipe network, installation patterns of the sprinkler, design temperature difference ,rate of temperature variability as well as the water leakage rate of the system. If the pressurized-type water supply unit is not only used to make the pressure of the system stable,but also used as the water tank,then the total cubage shall be the bigger one.
