Abstract
To provide a technology for enabling a user or the like to support the grasp of a fatigue state of piping of a refrigerant circuit.SOLUTION: According to one embodiment of this disclosure, an information processing device 200 acquires information on a detection result of a prescribed state (e.g., a protectively stopped state, an overloaded state, a state in which an effective value of a drive current or a specific frequency component exceeds prescribed reference, or a state of passing through a specific rotation speed at which use during operation is prohibited) of a compressor 12 to be a factor of abnormal vibrations of the compressor 12 provided in a refrigerant circuit 10, and outputs information on fatigue of piping of the refrigerant circuit 10 in the case that an index value that changes according to an integrated time or the number of integration times of the prescribed state exceeds a prescribed threshold in its change direction.SELECTED DRAWING: Figure 4
