摘要： PROBLEM TO BE SOLVED: To provide an air conditioner preventing the lowering of concentration of refrigerating machine oil by a refrigerant flooding state in a compressor.SOLUTION: An air conditioner is provided with an inside low pressure type compressor; a receiver capable of collecting refrigerating machine oil; and oil concentration detecting means for detecting the concentration of the refrigerating machine oil in the compressor. During the operation of the compressor, if a detection value detected by the oil concentration detecting means becomes a set value or more, a part of the refrigerating machine oil in the compressor is collected in the receiver by oil level difference between the compressor and the receiver. While the operation of the compressor is stopped, the receiver is insulated from a refrigerating cycle. When the compressor is started, if the detection value detected by the oil concentration detecting means is the set value or less, the refrigerating machine oil of high concentration collected in the receiver is supplied to the compressor by differential pressure between the compressor and the receiver.
