Abstract

The object of the invention is to provide a new method and a new installation for fighting fire, which more effectively than earlier known methods and installations prevent fire smoke from spreading and causing damage, in particular for relatively large units, such as hotels, passenger ships and various public spaces, e.g. restaurants. The object is achieved by producing, utilizing at least one sprinkler or spray head spraying high pressure liquid in the form of small droplets, like a fog, into an out-going ventilation or air condition duct of said unit, a suction from a monitored space into said outgoing ventilation or air condition duct, in order to remove smoke gases from the monitored space.
