置。In the refrigeration system described above, the low-stage compressor 1, the high-stage compressor 4, the condenser 6, and the evaporator 8, all of which are hermetic compressors, are connected in sequence to compress the circulating refrigerant in two stages. An oil separator 5 is provided only on the discharge side of the high-stage compressor 4 to separate lubricating oil in the refrigerant and return it to the high-stage compressor 4.
The refrigeration system is characterized in that lubricating oil therein can be bypassed into the low-stage compressor 1 via a float valve 45 that opens when the oil level exceeds a proper oil level of 1°.
