摘　　要：冷凝水反流是吸气式火灾自动报警系统在古建筑展厅中使用经常遇到的问题。为解决因冷凝水反流导致的设备故障,采用对故宫某展馆温度、湿度现场实时监测,以便为解决问题提供依据。结果表明:在7、8月间,空气相对湿度大多超过60%,且古建筑闷顶的上、下空间温差较大,容易在火灾报警系统吸气过程中形成冷凝水,由此提出加装重力疏水装置的优化改造方案,可有效控制冷凝水倒流至报警机。通过2年的实际使用情况验证,有效地解决了冷凝水回流的问题,具有较好的应用效果。The back flow of condensed water frequently leads to aspirating fire alarm system malfunction in the galleries of ancient architecture.By real-time monitoring the temperature and humidity of a certain gallery of the Palace Museum,this paper proposed solutions to deal with the equipment malfunction cause by the back flow of condensed water.The result are as follows.The humidity is high and the temperature differential below and above the ceiling of the ancient architecture is relatively high between July and August which made condensed water be generated easily in the aspiration system.This paper proved that by installing a gravity drainage device,the back flow of condensed water can be solved effectively.
