The heat exchanging portion 15 has a multi-layer structure in which, for example, cardboard sheets are stacked, and is in a state where a large number of holes are penetrated in the front-rear direction. The direction of this hole is the same as the axial direction of the cylindrical body 3 and the axial direction of the suction pipe 24. In addition, the state where the some thin plate was located in a line along the same direction like the heat exchanger of an air conditioner may be sufficient. In the present embodiment, the heat exchanging unit 15 may be a paper soaked with water, a fine mesh metal net, a fiber metal, or the like.

Hot water is supplied by spraying or jetting to heat the heat exchanging unit 15, and the air that has passed through the heat exchanging unit 15 is warmed from the branch pipe 25 through the suction pipe 24 to the centrifugal blower (centrifugal compressor). After being sucked in, it is sent from the scroll casing 6 as a discharge part to the ventilation pipe. The warmed air sent to the ventilation pipe is used for room heating and air replacement.

When the temperature is high, the switching plate 55 is put into a state in which the suction pipe 24 is closed and the branch pipe 25 is opened, and the cold water in the cold water tank 17 is supplied from the nozzle 18 to the heat exchanging section 15 by jetting or the like. After the section 15 is cooled and the air cooled through the heat exchange section 15 is sucked into the centrifugal blower (centrifugal compressor) from the branch pipe 25 through the suction pipe 24, the scroll casing 6 as the discharge section is used. Sent to ventilator. The cooled air sent to the ventilation pipe is used for cooling the room and replacing the air.

When the temperature is not too high or low, the switching plate 55 is in a state in which the branch pipe 25 is closed and the suction pipe 24 is opened, and the outside air is taken in as it is to replace the room air. Thus, by controlling the temperature of the air sucked into the centrifugal fluid machine, it can be used as an air conditioner capable of temperature control. It should be noted that the odor in the room can be eliminated by forcibly introducing air into the room. The suction pipe 24 may be extended and disposed indoors to discharge air from an indoor toilet or the like.

Therefore, when the temperature is equal to or higher than the set upper limit temperature or lower than the set lower limit temperature, the switching plate 55 is brought into a state in which the suction pipe 24 is closed and the branch pipe 25 is opened. In some cases, the branch pipe 25 may be closed and the suction pipe 24 may be opened. In addition, a valve or a pump is supplied by the control device so that cold water is supplied from the cold water tank 17 to the nozzle 18 when the temperature is equal to or higher than the upper limit temperature, and hot water is supplied from the hot water tank 16 to the nozzle 18 when the temperature is lower than the lower limit temperature. It may be controlled.

The air pushed out from the driven impeller 51 by centrifugal force is compressed and discharged by a diffuser provided in the air flow path from the driven impeller 51 to the scroll casing 6. In the present embodiment, the centrifugal fluid machine is used for blowing air from the air conditioner 1. However, the centrifugal fluid machine can be used as a device for supplying compressed air instead of simply blowing. The power of blowing and compression is wind power, and the operation cost can be reduced. Further, when compressed air is used in the air conditioner 1, the compressed air may be stored in an air tank or the like and then used for air conditioning. In this case, it is possible to blow air for air conditioning without being affected by changes in wind strength. In this case, it is preferable that the heat exchanger 10 controls the temperature by supplying air from an air tank.

As described above, the centrifugal fluid machine according to the present embodiment can perform blowing and air compression using natural wind. That is, it can be used for blowing and air compression without requiring power supply equipment. When compressing air with a centrifugal fluid machine, the compressed air can be used as a power source for power generators and other mechanical devices, or for oxygen concentrators using compressed air and zeolite. it can. When using compressed air as a power source, for example, the engine may be operated by filling the high pressure tank with compressed air and supplying the compressed air from the high pressure tank to the cylinder of the engine.

Further, the cylindrical body 3 is provided with a wind collecting portion 12 that collects and introduces wind into the cylindrical body 3, and efficiently collects natural wind by the wind collecting portion 12. Since it can introduce into the inside of the cylindrical body 3, the drive impeller 4 can be rotated efficiently and compressed air can be obtained. Further, the centrifugal fluid machine rotates the driven impeller 51 so as to blow air and compress air, so that the rotation of the driving impeller 4 can be used efficiently.

The speed increaser 7 is constituted by a planetary gear mechanism, the ring gear 71 of the planetary gear mechanism is attached to the drive impeller 4, the sun gear 72 is attached to the rotating shaft 5, and the planetary gear 73 is connected to the ring gear 71 and the sun gear. 72, the speed increase amount of the rotating shaft 5 can be easily adjusted by adjusting the number of teeth and the diameter of the ring gear 71, the planetary gear 73 and the sun gear 72.
In addition, a casing 45 is provided inside the drive impeller 4, a permanent magnet 9 is provided in one of the drive impeller 4 and the casing, and the coil 8 has a predetermined gap with the permanent magnet 9 on the other. Since the drive impeller 4 is rotated by natural wind, compressed air can be obtained and power can be generated by the cooperation of the permanent magnet 9 and the coil 8. In this case, compressed air can be stored in an air tank and electricity can be stored in a storage battery, and can be used without being affected by the presence or absence of wind or strength. The generated electricity may be used as a temperature control of the air conditioner 1 for a heater or a cooler. Further, when the centrifugal fluid machine is a centrifugal compressor, the centrifugal fluid machine may be used for a cooler by compressing and liquefying a refrigerant.

In the present embodiment, the planetary gear mechanism is employed as the speed increaser 7 that increases the rotational speed of the drive impeller 4 and transmits it to the rotary shaft 5. However, other various transmissions, speed increases A machine can be used.
