The invention relates to a system for reducing the risk of fire and extinguishing fires in a closed room and a method for operating such a system comprising a rotating heat exchanger system (20) and a device (1) for adjusting a leakage rate of a leak (S, S1, S2) at a gap-like opening, wherein the device (1) comprises a sealing member (2) having at least one chamber (3, 3a, 3b) and a line system (9) connected to the at least one chamber (3, 3a, 3b), a fluid being fed to the chamber (3, 3a, 3b) by the line system in a controlled fashion. According to the invention, the sealing member (2) is formed at least in part from a flexible material and the cross section of the sealing member can expand in the direction of the leak (S, S1, S2) when fluid is fed to the at least one chamber (3, 3a, 3b). Also, the system comprises an apparatus for providing an oxygen-displacing gas. The design-dependent gap spaces (S1, S2) at the rotor (21) of the rotating heat exchanger system (20) can be at least partially sealed off in a controlled fashion using the device (1) according to the invention. |
