VENTILATION AIR-CONDITIONING FACILITY FOR NUCLEAR POWER STATION, AND AIR-CONDITIONING AIRFLOW CONTROL METHOD THEREFOR

摘要

PPROBLEM TO BE SOLVED: To provide a ventilation air-conditioning facility for a nuclear power station capable of supplying an electric power source to a set of a blower and an exhausting fan, using a common inverter panel to save energy and to save a space, and applied easily to an existing nuclear power station, and an air-conditioning airflow control method therefor. PSOLUTION: This ventilation air-conditioning facility for the nuclear power station concerned in the present invention includes an air supply side air-conditioning facility 13 having the blower for supplying outside air to a ventilation air-conditioning objective area 12 of the nuclear power station 10, an exhaust side air-conditioning facility 14 having the exhausting fan 27 for discharging the air of ventilating the ventilation air-conditioning objective area 12, an exhaust cylinder 15 for diffusion-discharging an exhaust from the exhaust side air-conditioning facility 14 into the atmospheric air, and a common-to-blower/exhausting-fan power source system 40 for supplying the electric power source to the set of the blower 21 and the exhausting fan 27, and the blower 21 and the exhausting fan 27 constituting the set are inverter-controlled by the common-to-blower/exhausting-fan power source system 40 to variable-control a ventilation airflow rate.
