An oil holding tank (40 ) is commse (10c) of the compressor (10). Part of the refigc ) of the compressor (10</highliduced into the oil holding tank (40) so that the lcompressor (10 ) is introduced in oil holding tank (40) and the lubrication oil (L)that the lubrication oil (L) is allowed to flow ou(10c). The presence of the lubrication oil (L) is and the lubrication oil (L) which flows out is al (TK1) of the refrigerant introduced from the compitalic>c ). The presence of the lubricaemperature (TK2) of the lubrication oil (4) flowin the temperature (TK1 ) of the re of the result of the detection, it is judged whet ) to the oil holding tank (40</hn the case (10c) is appropriate. ht>) of the lubrication oil (4 ) flowing out from the oil holding tank (40 ). On the basis of the result of the detection, it is judged whether or not the amount of the lubrication oil (L) in the case (10 c ) is appropriate.
