酒店采用丹佛斯技术的高压灭火系统

阿尔斯克酒店灭火

多环芳烃泵是高压细水雾系统的核心


当阿尔斯克酒店在2019年春天开业时，丹麦桑德堡的工业港口的显著改造达到了新的高度。由丹麦著名建筑公司Henning Larsen设计的19层铝和玻璃高层酒店完成了弗兰克·盖里(Frank Gehry)为南日德兰半岛(Southern Jutland)最大的城市设计的海滨总体规划，拥有190间客房和弗伦斯堡(Flensborg)峡湾的壮丽景色。

丹佛斯为整个酒店提供低维护消防系统，采用多环芳烃泵、VRH、VCH和VDHT阀门的SEM-SAFE®高压细水雾系统。

高压细水雾系统与传统的湿管喷水灭火系统相比有许多优点，尤其是对于高层建筑。业主和建筑师喜欢它们，因为它们不需要在屋顶和多层楼上安装大口径水管和蓄水池，从而节省了宝贵的空间。这项技术也有效地保护玻璃表面免受热损伤。如果真的发生火灾，细水雾可以通过去除氧气和降低热量来抑制火焰，从而显著降低通量密度，从而减少水损害。

虽然安装起来比传统的洒水器简单，但这项技术确实依赖于比重力更复杂的东西来分散水。建筑物越高，面积越大，系统高压的可靠性就越重要，没有高压，特殊设计的喷嘴就不能雾化水。

丹佛斯消防安全公司的SEM-SAFE®高压细水雾系统需要持续的压力，这种规模的安装通常具有完全的冗余:如果主系统因任何原因出现故障，备份系统必须立即接管。为了确保故障安全性能，工程师指定了两个相同的泵组，每个泵组有四个高压泵。

丹佛斯消防安全公司市场解决方案经理Peter Knudsen解释说:“泵的可靠性当然很重要。“但对于这种安装，低维护和长维修间隔也是至关重要的。这就是为什么我们指定了丹佛斯PAH高压泵。除了行业领先的可靠性，它们的维护成本非常低。丹佛斯高压泵唯一需要的润滑是泵送介质，与其他技术相比，高压泵在前8000小时通常不需要维护，之后也很少需要维护。”

Alsik酒店于2019年5月开业，好评如潮。它独特的建筑、高端餐厅和大型水疗中心已经成为许多丹麦人和德国人的目的地。幸运的是，消防系统还没有被调用去扑灭任何火灾。但它以优异的成绩通过了所有常规测试。

正如预期的那样，到目前为止，我们还没有对任何八个PAH泵进行任何维护。“安装很简单，系统性能也没有问题。”

“新建的Alsik酒店有19层，这个装置展示了这种解决方案对高层建筑的好处。但是SEM-SAFE®高压水雾系统和PAH泵也已经安装在更高的建筑中，包括53层、310米的Varso塔，目前正在华沙建设中。”Knudsen说。
