Abstract: A target thermal sensation setter sets target thermal sensations for a finite number of parts into which the occupant is virtually divided. A cabin temperature controller individually controls a cabin air-conditioning unit and an auxiliary heater so that the thermal sensations of the respective parts of the occupant estimated by an occupant thermal sensation estimator fall within a range of the target thermal sensations.

Abstract: In a vehicle seat air-conditioning device, at least a first inlet, a second inlet, and an outlet are provided in a seat, and at least a first ventilation path, a portion of a second ventilation path, a ventilation path selection switch, a blower, and a third ventilation path are provided inside of the seat. To lead air to the third ventilation path, the ventilation path selection switch has: a first mode in which the first ventilation path is connected to the third ventilation path; a second mode in which the second ventilation path is connected to the third ventilation path; and a third mode in which the first ventilation path and the second ventilation path are connected to the third ventilation path. A controller switches between the modes of the ventilation path selection switch by selecting one of the first mode, the second mode, or the third mode.

Abstract: A comfort sensation calculation unit quantitatively calculates comfort sensation of an occupant from an RRI of the occupant A, and a target control value of a thermal environment control device is set based on the comfort sensation of the occupant. Therefore, it is possible to achieve air conditioning control that reflects the comfort sensation of the occupant. When a signal output from the comfort sensation calculation unit and a signal output from the occupant thermal sensation calculation unit do not correspond to each other, the signal output from the comfort sensation calculation unit is corrected, and the target control value is determined.

The micro gas turbine apparatus includes a first compressor, a burner, and a first turbine. The first turbine expands a combustion gas generated by the burner. The extracting cycle apparatus includes a second compressor and a second turbine. The second compressor receives a flow of extracted air that is generated by extracting a part of a working fluid discharged from the first compressor. The second turbine expands the working fluid discharged from the second compressor. The working fluid discharged from the second turbine cools down the first turbine.

The gas turbine unit (2) includes a first compressor (21) and a first expansion turbine (23) coupled to each other by a first shaft (22), a combustor (26), and a fuel tank (30). A fuel held in the fuel tank (30) circulates through a fuel circulation passage (31).

The flow rate of the air being blown by an exterior blower to pass through the path P4 closer to a refrigerant outlet of the exterior heat exchanger is set to be higher than that of the air being blown by the exterior blower to pass through the path P1 closer to a refrigerant inlet of the exterior heat exchanger. An air-conditioning controller activates cooling fans during a defrosting mode of operation.
