Abstract: An air conditioner of a track system vehicle includes two air conditioning units disposed in parallel in a horizontal direction and mounted on the roof of a vehicle, a plurality of outlets of two air conditioning units facing a vehicle center side, a first duct connecting two air conditioning units, and a second duct which bypasses to the vehicle ends.

Abstract: An electric vehicle control apparatus includes: a main power source (1) to (3) that supplies DC power; a power conversion device (8) that converts the DC power from the main power source to AC power, which it then supplies to a vehicle drive motor (9); an electric storage device (7) for accumulating DC power arranged in parallel between the main power source and power conversion device; a chopper device (5) that is connected in series with the electric storage device, and that supplies power to the electric storage device by chopping the DC power from the main power source and the regenerated DC power from the power conversion device; and a freewheeling diode (6) for passing current in a direction such as to supply current from the electric storage device to the power conversion device, connected in series with the electric storage device and in parallel with the chopper device.

Abstract: An air conditioner is realized which allows an interior space of a track system vehicle to be felt to be wide by maintaining a ceiling of the vehicle high, allows the protrusion amount from a roof to be kept low, and is able to uniformly air-condition the atmosphere in the interior of the vehicle. Two air conditioning units 20, in which constituent devices are disposed in parallel in a horizontal direction, are mounted on the roof 10c adjacent to vehicle end sides of the track system vehicle 10, a plurality of outlets 44 of two air conditioning units 20 face a vehicle center side, the outlets 44 on an inner side in a vehicle width direction are connected to the first ducts 50 disposed on the ceiling face, and the outlets 44 on end sides are connected to the second ducts 52 which bypass to the vehicle ends, thereby being disposed up to the vehicle ends.
