Abstract

A system (150) for controlling ventilation to a turbine enclosure (92) includes an air inlet filter system (152), a ventilation fan (154) to extract an air flow (156) from the air inlet filter system (152), and an air delivery system (160) including a plurality of conduits (162). Each conduit (162) delivers the air flow (156) to one of a plurality of ventilation inlets (164) defined in the turbine enclosure (92). A motorized volume control damper (170) is operably coupled to each of the plurality of ventilation inlets (164) and is configured to control a volume of air flow (156) entering a respective ventilation inlet (164) through a respective conduit (162). A controller (180) is configured to control each motorized volume control damper (170) to evenly distribute the air flow (156) to each of the plurality of ventilation inlets (164) regardless of a pressure drop (ΔP) across the ventilation fan (154).
