SYSTEM FOR AIR-CONDITIONING PIPING COMBINED WITH SPRINKLER PIPING

摘要

PURPOSE:To improve the construction workability and reduce the construction cost by constituting the system so that the sprinkler piping and the air- conditioning piping can be combined. CONSTITUTION:To a supply main pipe 3, a supply branch pipe 5 and an auxiliary pipe 11 are connected. The supply branch pipe 5 and the auxiliary pipe 11 are connected to a water collecting pipe 7, and the water collecting pipe 7 is connected to a reflux pipe 9. In the water supply branch pipe 5 and the auxiliary pipe 11, a sprinkler 17 is provided. A fan coil unit 19 is provided extending between the water supply branch pipe 5 and the auxiliary pipe 11. A fire extinguishing pipe 23 is connected to the supply main pipe 3. In a boundary of the water supply branch pipe 5 and the water collecting pipe 7, and in a boundary of the supply main pipe 3 and the auxiliary pipe 11, stop valves 13, 15 which are closed and opened at a usual time and at a fire time, respectively are provided, respectively. In a boundary of the water collecting pipe 7 and the reflux pipe 9, and in the supply main pipe 3 between the fire extinguishing pipe 23 and a heat source machine 1, stop valves 21, 29 which are opened and closed at a usual time and at a fire time, respectively are provided, respectively.
