られる。In the above, it is preferable to provide a known angle adjustment device such as a louver at the rear opening of the branching chamber and the cold air outlet of the duct in order to change the direction of the cold air. Ducts are used when air conditioning equipment is installed in the ceiling of a car.
It is preferable that the front end thereof be placed in front of the head of the person sitting in the front row of seats, and that the cold air outlet be directed diagonally downward to the rear. By doing so, it is possible to prevent the cold air from hitting the back of the head of the person sitting in the front row of seats, which is preferable for protecting the health of the person sitting in the front row. As the blower fan, for example, a sirocco fan is used. The condenser, compressor, liquid receiver, etc. of the cooling system are placed in the engine compartment of the automobile. In addition, this cooling device
It is mounted on the ceiling almost above the front row seats of a car.

ようになっているから。If the automotive cooling system of this invention is installed on the ceiling,
Cool air can be evenly supplied to the front and rear seats. In addition, it is equipped with two evaporators, and the cold air sent out from the evaporators is divided back and forth by a branch path, and the cold air is blown out from the opening and the cold air outlet of the duct to the rear seat side and the front seat side. This makes it possible to evenly supply cold air of almost the same temperature to the front seats and rear seats. Also, it blows out cold air from above.
車室内における冷気の流れがスムーズになり、車室内の
基部における温度分布をほぼ均等にすることができる。The flow of cold air in the vehicle interior becomes smooth, and the temperature distribution at the base of the vehicle interior can be made almost uniform.
