<p>PROBLEM TO BE SOLVED: To provide a technology enabling an index relevant to an amount of oil in an oil separator to be measured with high accuracy.SOLUTION: An oil separator is provided that includes: an oil separator body 41 in which a filter element 42 separates oil contained in refrigerant gas and an oil absorber 43 stores oil separated by the filter element 42; and a detecting part 50 which detects an index relevant to an amount of oil stored in the oil absorber 43. An inside of the oil separator body 41 is partitioned by the oil absorber 43 into an upper area 47a into which refrigerant gas flows from the outside of the oil separator and a lower area 47b for discharging the separated oil to the outside of the oil separator. The detecting part 50 may comprise a first pressure gauge 45a for detecting a pressure in the upper area 47a, a second pressure gauge 45b for detecting a pressure in the lower area 47b and a difference pressure obtaining part 46 for obtaining, as an index, a difference pressure between a pressure detected by the first pressure gauge 45a and a pressure detected by the second pressure gauge 45b.</p> |
