To effectively utilize the exhaust heat of a gas turbine through the year for an external conditioning unit that is operated by utilizing the exhaust heat of the gas turbine.
A desiccant rotor, a sensible heat exchanger, a humidification cooler, and a heater are provided at a body section (40) of the external conditioning unit 20. First air introduced into the body section (40) is dehumidified by the desiccant rotor, is cooled by the sensible heat exchanger, and then is cooled by the humidification cooler. Also, the heat of second air introduced to the body section (40) is absorbed and is heated before regenerating the desiccant rotor. The second air is heated by the exhaust heat of a gas turbine (11). Then, in cooling operation, the obtained first air at a low temperature is supplied into the room. On the other hand, in an intermediate season, the obtained first air at a low temperature is supplied to the gas turbine.
