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. Therefore, since a height of the vehicle is able to be reduced and the ceiling face of the vehicle center side region H, where the first ducts 50 are disposed, is able to be made higher, a space of the interior of the vehicle is felt to be wide. Also, pressure losses in the first ducts 50 are reduced, so that an air-conditioned temperature can be equalized.

Claims

1. An air conditioner of a track system vehicle, comprising:

an air conditioning unit which has constituent devices disposed in parallel in a transverse direction and is mounted on a roof of the vehicle,

wherein the air conditioning unit is provided close to an end portion in a longitudinal direction of the vehicle,

outlets for air-conditioned air are disposed facing a vehicle center side,

some of the outlets are connected to first ducts, which are disposed in a longitudinal direction of the vehicle along a back face of the roof and have outlets which face downward, and

remaining outlets are connected to second ducts, which bypass along the back face of the roof from the outlets to a vehicle end side, on which the air conditioning unit is mounted, thereby being disposed up to a vehicle end, and have outlets which face downward.

2. The air conditioner of a track system vehicle according to claim 1, wherein the air conditioning unit is 1-layered, and a vehicle exterior air suction fan, a vehicle interior air suction fan, a discharging fan, and air-conditioned air outlets, out of the constituent devices are disposed in this order from the vehicle end side toward the vehicle center side.

3. The air conditioner of a track system vehicle according to claim 1, wherein the air conditioning unit is 2-layered, and a condenser, a compressor, and a vehicle exterior air suction fan, out of the constituent devices are disposed on an upper layer, and on a lower layer, a vehicle interior air suction fan, a discharging fan, and air-conditioned air outlets are disposed in this order from the vehicle end side toward the vehicle center side.
