Abstract (en)
[origin: EP2375193A2] An air conditioner and a method of operating the same are provided. The air conditioner may include a plurality of compressors (100,100',100''), each of which may include a casing that stores oil therein, and an oil level detecting device (102,102',102'') that detects an oil level within the casing. Once oil levels within each of the plurality of compressors are detected, oil may be redistributed between the plurality of compressors without interrupting a normal operation of the air conditioner. Oil may be transferred from a compressor having an oil level greater than a desired amount to a compressor having an oil level less than the desired amount. If there remains a compressor that contains an insufficient amount of oil after redistributing the oil among the plurality of compressors, an oil collecting operation may be performed.
