Abstract
The apparatus for cooling intake air includes a heat exchanger for transmitting the cold energy of fuel to a heat medium through an intermediate heat medium having a different property from the heat medium, a pressure controller for controlling the pressure within the heat exchanger so that a temperature of the intermediate heat medium is kept higher than a solidifying point of the heat medium, and an intake air cooling system for cooling intake air to be introduced into the gas turbine using the heat medium cold energy. The intermediate heat medium may be condensable by the cold energy of the fuel and vaporizable by the heat medium or may have a solidifying point lower than the fuel.
