<p>PROBLEM TO BE SOLVED: To obtain a refrigeration cycle device capable of avoiding detection error due to changes in surrounding environmental conditions such as an ambient air temperature to improve accuracy of compressor degradation determination, and reducing diagnosis time for compressor degradation diagnosis.SOLUTION: In a refrigeration cycle device 100, an operation capacity of a compressor 1, a rotational speed of an outdoor blower 6, rotational speeds of indoor blowers 7a and 7b, and openings of expansion valves 4a and 4b are determined, and it is determined whether the compressor 1 degrades by comparing a determination index calculated when an operating state of a refrigerant circuit is a stationary state with a set degradation determination reference value.</p> |
