    Abstract: In a refrigeration cycle device in which a compressor is driven by power transmitted from an engine, a torque limiter is adapted to interrupt a transmission of the power from the engine to the compressor when a torque transmitted from the engine to the compressor becomes a predetermined value. A control unit is adapted to determine whether the transmission of the power from the engine to the compressor is interrupted by the torque limiter by determining whether a deviation of a refrigerant discharge pressure of the compressor is below a predetermined pressure when the control unit commands the compressor to change the refrigerant discharge flow amount of the compressor. Thus, the control unit can determine whether the torque limiter interrupts the transmission of power from the engine to the compressor without, using a compressor revolution sensor.
