Abstract
The invention relates to a preventing and extinguishing fires in enclosed spaces in which the internal air atmosphere is not permitted to exceed a predefined temperature value. In order not to have to increase the cooling capacity of an air conditioning system when inert gas is added to the internal air atmosphere to set or maintain a specific inertization level within an enclosed space, a system for the regulated discharging of inert gas into same is provided. The system includes a container for the provision and storage of the inert gas in liquified form, and a vaporizer connected to the container for vaporizing at least a portion of the inert gas and discharging same into the internal air atmosphere of the enclosed space. The vaporizer thereby directly or indirectly extracts the heat energy needed to vaporize the liquid inert gas from the internal air atmosphere of the enclosed space.
