PCT No. PCT/FI97/00523 Sec. 371 Date Apr. 8, 1998 Sec. 102(e) Date Apr. 8, 1998 PCT Filed Sep. 5, 1997 PCT Pub. No. WO98/09684 PCT Pub. Date Mar. 12, 1998An installation for fighting fire in a space which includes a spray head (1a', 2a') of such a type that it is capable of producing extinguishing medium in the form of a finely divided liquid mist with a great penetrating ability and a simultaneous suction near the spray head. To obtain an installation which as regards its construction is simple and with which a fire in a space can be very efficiently extinguished so that the fumes are purified at the same time as the amount of water can be very small, the spray head (1a', 2a'', 1b', 2b') is arranged in a pipe (3a', 3b') with a suction opening (67a', 67b') at a distance of 1 to 10 m from the floor level (24) of the room and a spray opening (45a', 45') near the floor level, whereby the spray head is arranged to spray in the direction from the suction opening to the spray opening to create a suction in the suction opening. |
