摘要： PROBLEM TO BE SOLVED: To restrict the formation of condensed water to improve the cooling efficiency of a heat exchanger in the heat exchanger for cooling intake air sucked into an air compressor of a gas turbine device, and thereby enhance the combined efficiency of the gas turbine device. SOLUTION: A cooling quantity controlling means 30 for controlling the cooling quantity of a heat exchanger is provided in a gas turbine device. The cooling quantity controlling means 30 is provided with an intake air temperature detecting element 31 for detecting the temperature at the neighborhood of an intake outlet in a water-cooled heat exchanger 2, an intake air humidity detecting element 32 for detecting the intake air humidity at the neighborhood of an intake air inlet part, an operation part 33 for operating the dew-point temperature of the intake air from the detected value of the intake air humidity, and a control part 34 for reducing the rotating speed of a pump 18 when the intake air temperature is reduced lower than the dew-point temperature. Cooling water is supplied by a cooling water supply part 8 provided with an ice-thermal storage tank 16, and a refrigerator 17 for cooling the cooling water of the ice-thermal storage tank 16 to form ice.

摘要： PROBLEM TO BE SOLVED: To efficiently cool intake air to a gas turbine device using a small quantity of cooling medium. SOLUTION: An ice heat storage device 22 is connected to a cooling path 6 separated by a partition wall 8 provided at an intermediate part of an intake path 2 extended from an intake port 2a to an air compressor 1 of a gas turbine device. The ice heat storage device 22 is charged with heat storage capsules 21 with heat storage bodies sealed inside, and intake air 9 is cooled coming in direct contact with the heat storage capsules 21 previously cooled in the at least partially frozen state of the heat storage bodies by a refrigerating device 17.
