| description | PROBLEM TO BE SOLVED: To improve service property by facilitating the analysis for failure or breakage cause of an air conditioner. SOLUTION: The air conditioner comprises an outdoor unit 15 having an inverter system 17 for inverter-controlling a compressor 6 and a drive motor, an indoor unit 14 connected to the outdoor unit, a signal line and a pipe, and a remote control 13 for communicating with the indoor unit to perform setting of room temperature. The inverter system 17 includes a fin temperature detection means 1 for detecting the temperature of a radiation fin for performing the heat radiation of the inverter system 17, a DC voltage detection means 2 for detecting the DC voltage supplied for the inverter control, a motor current detection means 3 for detecting the operating current of the compressor, and an abnormality detection means 5 for detecting abnormality based on the value of at least any one of the temperature of the radiation fin, the DC voltage and the operating current. In this air conditioner, the temperature of the radiation fin, the DC voltage and the operation current are stored. COPYRIGHT: (C)2005,JPO&NCIPI |
