- Abstract:
- Application of wet electric heat tracing fire hydrant system in airport underpass in cold area has problems such as high energy consumption and high operating cost. According to the current standard, atlas and engineering practice, a design scheme of dry fire hydrant system was proposed. The pipe volume calculation, switching device selection, system control method, pipe network layout and water hammer protection of dry hydrant system in Harbin Taiping international airport phase Ⅱ project were analyzed from multiple perspectives, and the calculation method and control method were introduced. In addition, the switching device of dry fire hydrant system was linked with the automatic fire alarm system set in the underpass. Through remote control, the time of dry and wet conversion in the system is saved, and a wider space for the application of dry fire hydrant system is provided.
