する冷凍装置。 In a refrigeration system in which a variable displacement compressor and a constant displacement compressor, the capacity of which changes automatically according to the refrigeration load, are installed in parallel in a refrigerant circuit, the refrigerant is stored in the variable displacement compressor. An oil level sensor is provided that operates when it is detected that the oil level of the refrigerating machine oil has fallen below a dangerous value, and the oil level sensor operates while both of the compressors are operating or only the variable displacement compressor is operating. A refrigeration system characterized by comprising a control means for stopping the variable displacement compressor and operating the constant displacement compressor when the above occurs.
