Conventionally, in a turbo chiller configured with a discharge duct 6 that guides discharge gas from the compressor 3 to the condenser 2, the compressor 3
Since the suction and discharge parts of 2 were connected to each other on two sides, a and b, first the compressor 3 was attached to the discharge part B, and then the suction part A
It was necessary to pay cash, and it took a lot of man-hours to manufacture.

。In addition, in order to cool the main motor 4, refrigerant liquid is supplied from the bottom of the condenser to the main motor 4 through a pipe 7, and evaporated gas generated by cooling the main motor 4 is returned to the evaporator 1 through a pipe 8. was. On the other hand, in the compressor 3, gas leaking from the back labyrinth 1o of the impeller 9 was returned to the suction side of the impeller 3 via a pipe 11. These pipes 7, 8, 11 and the compressor 3 had to compete for cash at the assembly stage, which increased the number of manufacturing steps and had the disadvantage that there were many points where internal gas leaked.

欠点があった。Furthermore, since the compressor 3 was constructed to be mounted on the heat exchanger, a mounting base was provided on the heat exchanger. In this case, the horizontal positioning of the compressor 3 was performed using a reliner, which was used as a cash-for-money method to adjust the level, which had the disadvantage of requiring a lot of manufacturing man-hours.

In addition to this, an overhang structure is also possible by supporting the compressor at the interface between the suction duct and the compressor.
以下、本発明の一実施例を第５図〜第８図により説明す

ある通りである。The compressor 4 shown in the figure has a shape in which the gas flow path after exiting the scroll is bent toward the suction duct 1. The compressor 4 and the suction duct 5 are connected via a flange 7, and the compressor 4 is connected to the flange 7.
A notch d necessary for passage of the discharged gas is formed, and the boundary between the suction part C and the discharge part d of the compressor is sealed with a sheet packing. On the other hand, inside the suction duct 5, for example, a discharge duct 6 is formed using a part of the wall of the suction duct, and communicates with a gas passage hole provided in the condenser 2. The gas flow is as shown by the white arrows in FIGS. 5 and 6.

けられた通過穴ｆを通じて吸込ダクト内に戻している。A refrigerant liquid for refrigerant cooling the main motor 8 is supplied from the bottom of the condenser 2, and this piping 9 is led to the flange portion 7 of the suction duct 5. On the other hand, on the compressor casing side, a passage for supplying refrigerant liquid to the main motor is provided, and the refrigerant liquid is supplied through the refrigerant liquid passage hole 〇 provided in the flange 7 of the suction duct 5. Further, the evaporated gas generated by cooling the main motor 8 is returned into the suction duct through a passage hole f provided in the flange 7, also via a passage provided in the compressor casing.

それより小さければ、長手方向に長くても占有スペース
としては変わらない。One embodiment has been described above, but in this embodiment, the discharge duct 6 can be formed by using a portion of the inner wall of the suction duct 5, which reduces the number of required parts and reduces manufacturing costs. Since the flange 7 is directly fixed to the heat exchanger by welding, sufficient rigidity can be obtained to support the compressor in an overbank manner by the flange 7. Further, if such a suction duct 5 is equal to or smaller than the connecting flange 7 of the compressor 4, the occupied space remains the same even if it is longer in the longitudinal direction.

がはかれるとともに。As described above, according to the present invention, the gas suction part and the discharge part of the compressor, as well as other necessary refrigerant liquid and gas, can be exchanged between the suction duct and the mounting flange surface of the compressor. This eliminates the need for this, and significantly reduces manufacturing man-hours.

れる。Reliability against gas leaks is improved by reducing the number of locations where gas leaks may occur from 8 to 1N2i locations. In addition, by reducing the weight of the compressor, it becomes possible to support the suction duct and overhang, thereby reducing manufacturing costs by eliminating assembly man-hours and unnecessary supports.
