Abstract
Device and method for detecting anomaly of an air conditioner, the method including the steps of (1) detecting an acoustic emission signal from a compressor in the air conditioner during operation of the air conditioner, (2) detecting parameters of particular components from the detected acoustic emission signal, and (3) comparing the detected parameters to respective references, to determine anomaly of the air conditioner on the whole, whereby permitting the most reliable detection of anomaly of the air conditioner.
Claims15
A device for detecting anomaly of an air conditioner, comprising:
- a body having an inwardly curved surface to fit an outer side form of a compressor in an air conditioner;
- a sensor fitted to the inwardly curved surface for sensing an AE signal generated at the compressor, wherein the device is brought into close contact with the compressor in the vicinity of a vane in the compressor, for sensing an acoustic emission signal from the compressor in the air conditioner;
- and
- a comparison and determining part for comparing an AE absolute average to a reference for determining anomaly of the air conditioner, the AE energy being a sum of signals of a frequency among signals detected at the sensor device divided by a number of entire data.
A device for detecting an anomaly of an air conditioner, comprising:
- a body configured to be brought into close contact with a compressor of an air conditioner;
- and
- an AE sensor fitted to the body, wherein the AE sensor is configured to sense acoustic emissions of a compressor.
A device for detecting anomaly of an air conditioner, comprising:
- a body having an inwardly curved surface configured to fit an outer side form of a compressor in an air conditioner;
- means for detecting acoustic emissions from a compressor in the air conditioner during operation of the air conditioner;
- and
- means for determining whether the compressor is abnormal based on an output of the detecting means.
