<P>PROBLEM TO BE SOLVED: To provide a generator capable of preventing injury caused by a large opening/closing rotational force of a door at the after-cooling of the generator. <P>SOLUTION: In this air supply/exhaust system of a generator room R, a part of outside air taken in an enclosure E through the generator room R from an intake fan F<SB POS="POST">0</SB>is used for fuel air, ventilation in the enclosure E, and cooling air for cooling a gas turbine generator D during a power generation mode, and outside air taken inside is used only for cooling air in an after-cooling mode. The intake fan F<SB POS="POST">0</SB>has a structure in which an air intake volume is variable. Pressure sensors S<SB POS="POST">1</SB>, S<SB POS="POST">2</SB>for measuring differential pressure between the inside and the outside of the generator room are installed inside and outside the generator room R. The air intake volume is smaller in the after-cooling mode than that at the power generation mode by adjusting the air intake volume of the intake fan F<SB POS="POST">0</SB>so that the differential pressure inside and outside the generator room R measured by the pressure sensors S<SB POS="POST">1</SB>, S<SB POS="POST">2</SB>reaches a set value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
