ェクタ１１が直列に挿入されている。Refrigerant flow paths 9 and 10 are provided for guiding a portion of high-temperature, high-pressure refrigerant gas from a portion of the swirl chamber 7 to the oil tank 8, and an ejector 11 is inserted in series between the refrigerant flow paths 9 and 10.

引作用により吸引して油タンク８に回収する。This oil adheres to the heat transfer tubes and reduces heat transfer efficiency and causes various problems, so the oil separation chamber 14 is used to remove and collect the oil.
The oil accumulated at the bottom is sucked by the suction action of the ejector 11 and collected into the oil tank 8.
しかしこの様にして回収した油にはまだ可成りの量の冷
媒液が含まれているので、油の粘度が低くなると共に油
のフォーミング現象が発生し易い欠点があった。However, since the oil recovered in this manner still contains a considerable amount of refrigerant liquid, the viscosity of the oil is low and the oil is liable to form.

クル中の高圧部である凝縮器に導かれているため圧縮機

なり、従って加熱量が少となり冷媒を十分除去すること
ができなかった。To prevent this, some oil stored in an oil tank is heated with part of the discharge gas from the compressor to evaporate and remove the refrigerant mixed in the oil. Since the refrigerant is led to the condenser, which is a high-pressure part of the refrigerant, the differential pressure from the discharge port of the compressor is small, and the flow rate of gas for heating is small, so the amount of heating is small and the refrigerant cannot be removed sufficiently. .

This is the purpose.

ターボ冷凍機である。The present invention provides a turbo refrigerator in which a refrigeration cycle is formed by a turbo compressor, an evaporator, a condenser, and a refrigerant path that connects these devices. An oil separation chamber is provided at the bottom of the casing that separates and recovers oil mixed in the suction refrigerant, and a part of the refrigerant discharged from the turbo compressor is guided to the oil separation chamber to remove the stored oil. The turbo refrigerator is characterized in that after heating the refrigeration cycle, the refrigeration cycle is heated and then guided to the low pressure section of the refrigeration cycle.

る。To explain the present invention with reference to the drawings, an embodiment of the present invention is shown in FIG. The refrigerant is connected to the swirl chamber 7 through a refrigerant passage 20, and the other is led to an evaporator 2ζ, which is a low-pressure refrigerant section in the refrigeration cycle, through a refrigerant flow path 21.

離室１４中の油を加熱せしめ混入している冷媒液を蒸発
して分離せしめる。During operation, a portion of the high-pressure superheated refrigerant gas in the swirl chamber 7 is introduced into the introduction pipe 19 through the refrigerant flow path 20, heats the oil in the oil separation chamber 14, and evaporates and separates the mixed refrigerant liquid. urge
導入管１９を出た冷媒（ガス、液体又はその混合物）は
冷媒流路２１を経て冷凍サイクル中の冷媒低圧部である
蒸発器２に供給される。The refrigerant (gas, liquid, or a mixture thereof) exiting the introduction pipe 19 is supplied to the evaporator 2, which is a low-pressure refrigerant section in the refrigeration cycle, through a refrigerant flow path 21.

に回収された油は油の含有率が極めて高く、粘度も犬で
あり、フォーミング現象を防ぐことができる。Most of the refrigerant liquid contained in the oil in the oil separation chamber 14 is evaporated and removed by heating, and the amount of refrigerant entering the oil tank 8 from the refrigerant flow path 10 is extremely small.
The oil recovered has an extremely high oil content and a moderate viscosity, which can prevent the foaming phenomenon.
冷媒流路２１の接続先は、冷媒サイクル系の低圧部なら
どこでもよい。The refrigerant flow path 21 may be connected to any low-pressure part of the refrigerant cycle system.

るものである。With this invention, the pressure difference of the heated gas is increased, the amount of heating is increased, evaporation is promoted, and effective oil separation can be performed, and the refrigerant is sufficiently removed, and the amount of refrigerant liquid in the recovered oil is suppressed to a trace amount. Therefore, it is possible to provide a centrifugal refrigerator that can recover oil with a high oil content, have a high oil viscosity, and prevent the forming phenomenon, and has extremely effective effects in practical use.
