PROBLEM TO BE SOLVED: To provide a technique that can appropriately estimate a circulation state of oil that circulates in a compressor.SOLUTION: In a compressor 10 that compresses refrigerant gas returned from a refrigerator 30 and supplies it to the refrigerator 30, a compression capsule 11 compresses the refrigerant gas and cools compression heat of the refrigerant gas by using oil. An oil separator 15 separates the oil contained in the refrigerant gas compressed by the compression capsule 11 and stores it. A capsule oil level gauge 41 measures an oil level of the oil in the compression capsule 11. A separator oil level gauge 42 measures an oil level of the oil in the oil separator 15. |
