To obtain an air-conditioning apparatus which is able to prevent an accident due to a breakdown or lowering of an energy-saving efficiency in an end stage of product life before occurrence by detecting a state in which the breakdown or the lowering of the energy-saving efficiency in association with deterioration with age is occurred, or a state which is susceptible to the occurrence of the breakdown or the lowering of the energy-saving efficiency in association with the deterioration with age. A measuring unit 103 configured to acquire operating-state data of the air-conditioning apparatus, a controller 101 configured to control at least one of the operating capacity of a compressor 1, the air volume of an outdoor air blower 4, the air volume of an indoor air blower 8, and the opening of an expansion valve 5, and a storage 104 for storing the operating-state data are provided therein, and the controller 101 stores information about the operating-state data in the storage 104 when the operating-state data satisfies predetermined conditions, compares the operating-state data stored in the storage 104 and current operating-state data, and detects an abnormal state or a symptom of abnormality of the air-conditioning apparatus. |
