PROBLEM TO BE SOLVED: To provide a dehumidification system in a turbine condenser, not causing air leakage from a dehumidification device using a desiccant rotor for dehumidify air in the condenser and allowing stable dehumidification effect to be obtained without depending on air humidity change inside the condenser, in maintenance construction in the turbine condenser of a nuclear power plant.SOLUTION: The dehumidification system in the turbine condenser includes: an air suction port for sucking air in the condenser; an HEPA filter connected to the air suction port via a duct; a dehumidification device having a desiccant rotor connected to a subsequent stage of the HEPA filter; a blower fan connected to a subsequent stage of the dehumidification device; a reproduction heater having a duct connecting an exhaust side of the blower fan and an exhaust port installed in the condenser, and supplying heated air to a reproduction part of the desiccant rotor; and a reproduction fan for sucking exhaust air from the reproduction part of the desiccant rotor. |
