Ventilation system connected to a closed and heat accumulating air heating system is designed to remedy the problem that arises upon release and concentration of radioactive gasses in a closed cavity (6) in a stone material construction (5) that limits the room space (10) of the building and any release of such gases into the room space (10). The solution provided by this invention can be used not only for ventilation of the cavity (6), but also for ventilation and temporary heating of the room space (10). The problem has been solved by connecting the exhaust air ducts (11) for the room space to a spot or spots in the area (6-1) on the negative pressure side in the closed system (1-9). In a spot between the fan (1) and the duct system (4) for supply to the cavity (6), a duct (13) has been installed that leads to the outside air. The system has been equipped with components (12 and 14) on the overpressure side that distribute the air in the cavities (16) and out, or on the negative pressure side that combine the air from the cavities with the exhaust air from the room (10). The cavity (6) is ventilated with a mixture of heated air and the room's (10) exhaust air.<IMAGE> |
