PROBLEM TO BE SOLVED: To acquire a compressor deterioration diagnostic device and the like for performing deterioration diagnosis of a compressor while performing operation for maintaining stability of temperature and the like in an object space which a refrigeration cycle device heats or cool and the like.SOLUTION: A compressor deterioration diagnostic device 30 of a refrigeration cycle device for configuring a refrigerant circuit by connecting a compressor 1 and the like by piping includes: a measurement unit 30a for measuring a physical amount detected by various types of detection means; a drive unit 30c for performing operation control by driving the compressor 1; and a determination unit 30e for performing deterioration diagnosis of the compressor by the determination based on the measurement result of the measurement unit 30a. The determination unit 30e determines whether or not to start a deterioration diagnosis operation for measuring a physical amount related to the deterioration diagnosis of the compressor 1, and when it determines to start the deterioration diagnosis operation, it allows the drive unit 30c to perform operation for increasing temperature in an object space by changing the setting temperature high, and when it determines that the temperature has reached the setting temperature, it performs processing of allowing the drive unit 30c to perform the deterioration diagnosis operation before the temperature in the object space drops to predetermined temperature. |
