Estimating the term…
To predict and detect a failure in a compressor provided in an air conditioner, the air conditioner is provided with: a heat exchanger; the compressor; piping connecting the heat exchanger and the compressor with each other; and a control unit controlling the compressor and having a compressor failure predicting and detecting means, and in this air conditioner, the compressor failure predicting and detecting means of the control unit includes: a current detecting part detecting a driving current driving the compressor; a pulsation detecting part detecting pulsation in a driving current detected by the current detecting part; and an anomaly determining part predicting or detecting any failure in the compressor based on a magnitude and a duration of pulsation in a driving current detected by the pulsation detecting part.
An air conditioner, comprising:
A method for predicting and detecting a failure in a compressor in an air conditioner including a heat exchanger, the compressor having a motor, piping connecting the heat exchanger and the compressor, and a controller connected to the compressor, the method comprising the steps of:
