Abstract

PURPOSE:To reduce the capacity of air-supply fan facilities, and to improve maintenance capability by installing air-supply fans concentrated at each housing at one position and making them even to the same kind. CONSTITUTION:Air supplied to a nuclear reactor housing 4, an auxiliary housing 8, a turbine housing 12 and a waste treating housing 16 is treated by treating- device units 18 installed into a centralized outside-air treating device 17, and forwarded into each housing through air-supply ducts 3, 7, 11, 15 by centralized air-supply fans 19. Fixed air-quantity devices are each set up to these air-supply ducts, and each quantity of air designed can be blasted to several housing by air actuating dampers. According to such constitution, one air-supply fan 19 is used as a spare, other three ones can supply air to all of each housing 4, 8, 12, 16, installation of only four in total air-supply fans 19 of one kind is necessary instead of eight if each two fans of four kinds are installed for each houses 4, 8, 12, 16, and the intercangeability and maintenance capability of the parts of the air-supply fans are improved remarkably.

The invention will now be described in detail. Reactor building 4. Auxiliary building 8. Air supply to the turbine building 12 and waste treatment building 16 is blown to each building through installations 1 and 15 in a central outside air treatment system 17. Each of these air supply ducts is equipped with a constant air volume device, and an air-operated damper allows each designed air volume to be blown to each building.
