Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, completeDescribe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based onEmbodiment in the present invention, those of ordinary skill in the art obtained under not making creative work premise all otherEmbodiment, broadly falls into the scope of protection of the invention.

Refer to Fig. 1, in the embodiment of the present invention: centrifugal refrierator in a kind of rotating boosting, including 1, in outer supercharging fromHeart device, 2, generator, 3, vacuum pump, 4, power motor, 5, interior centrifugal film, 6, main frame vaporizer, 7, throttle expansion valve, 8, cryogenPump, 9, cooling tower, 10, refrigerant pump, 11, indoor evaporator, 12, expansion tank, 13, cooling chamber, 14, water as refrigerant return pipe, 15Cooling water pump, 16 outer supercharging sheets；In described outer supercharging, centrifuge 1 is arranged in the middle part of generator 2, and is connected with power motor 4；InstituteState vacuum pump 3 to be connected with generator 2；In described outer increasing centrifuge 1 outer wall be provided with outer supercharging sheet 16 inwall be provided with in fromLamination 5 and throttle expansion valve 7；Described water as refrigerant return pipe 14 connects cooling chamber 13 and generator 2, and arranges on water pipe 14It is provided with the cryogenic fluid pump 8 of power；Described cooling tower 9 is connected with cooling chamber 13；Described refrigerant pump 10 be arranged at main frame vaporizer 6 withIndoor evaporator 11 connects；Described main frame vaporizer 6 is arranged in outer supercharging in centrifuge 1；Described expansion tank 12 is by pipeLine is connected with coolant water pipe.

Further；Centrifugal refrigeration machine in outer supercharging, refrigerant solution injection rate is that the capacity of generator and cooling chamber deductsIn outer supercharging, the capacity of centrifuge deducts cooling chamber half capacity again and is advisable.

The present invention is in use: first evacuation, opens cryogenic fluid pump after meeting operating mode；Owing to the flow of water pump is more than occurringThe device flow by throttle expansion valve, refrigerant pump works after some times, and the water level forming generator uprises, and in outer superchargingWater in centrifuge is displaced by putting in generator, and the low pressure operating mode in generator is also displaced by centrifuge to outer superchargingIn；Open work drive motor.In making outer supercharging, centrifuge runs up.The water in generator is made to pass through throttling expansion after superchargingEnter in outer supercharging in centrifuge；High-temperature water is defined after absorbing heat after forming the water as refrigerant spray coolant water pipe of low-temp low-pressureSteam, is got rid of into cooling chamber by interior centrifugal film, because the cooling chamber pressure in centrifuge that compares in outer supercharging is slightly higher, and cooling chamber temperatureRelatively low, a high-temperature water vapor part condenses into aqueous water because of pressure change, and another part cooling tube at hydroecium top that is cooled is metCold junction becomes aqueous water.Again taken back generator by cryogenic fluid pump after cooled water cooling, go round and begin again, reach the mesh ground that freezes.

It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er QieIn the case of the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matterFrom the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, the scope of the present invention is by appended powerProfit requires rather than described above limits, it is intended that all by fall in the implication of equivalency and scope of claimChange is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.

The above, only presently preferred embodiments of the present invention, not in order to limit the present invention, every skill according to the present inventionAny trickle amendment, equivalent and the improvement that above example is made by art essence, should be included in technical solution of the present inventionProtection domain within.
