Chilled intake air for increased power generation
A mobile source of electricity is converted from a transportation mode to an operational mode. A turbine disposed on the mobile source of electricity is operated to generate electricity in the operational mode. A first control valve is operated to feed a cooling agent from a cooling agent source into a heat transfer apparatus disposed in an air intake flow path of the turbine to cool intake air. A second control valve is operated to vent from the heat transfer apparatus, the cooling agent that is heated by absorbing heat from the intake air flowing through the air intake flow path. A controller controls the first and second control valves to maintain the cooling agent having predetermined properties in the heat transfer apparatus.
