回路。 A compressor driven at a variable frequency, a condenser, a pressure reducing device, and an evaporator are connected via piping, and the compressor is connected to a closed container with an oil reservoir at the bottom, and a compressor housed in this container. In the refrigerant circuit, the refrigerant compressed by the compressor main body is discharged into a closed container, and the refrigerant is discharged from the upper part of the container to the discharge pipe. A bypass pipe having an on-off valve is connected to the outlet pipe, and this on-off valve is a valve that is opened by a control device for a certain period of time from the time when the operating frequency of the compressor decreases at startup when the operating frequency of the compressor gradually increases. A refrigerant circuit characterized by:
