Air conditioner compressor winding temperature calculation calibration method

Abstract

The invention provides an air conditioner compressor winding temperature calculation and calibration method, and belongs to the field of winding temperature calculation. At present, parameter difference inevitably exists in manufacturing of a compressor. In order to solve the problem that if the same standard magnetic flux is used as a reference for calculating the temperature of a motor winding in a compressor, difference exists in calculation of the winding temperature, the method comprises the steps: firstly, in the production and assembly stage of the compressor, adding a magnetic flux detection procedure, and employing a detected magnetic flux value for generating an information code; secondly, after the compressor is assembled into the air conditioner outdoor unit, acquiring the accurate magnetic flux of a motor winding of the compressor according to the information code; calculating a winding temperature value based on the accurate magnetic flux. By accurately recording the magnetic flux value of the air conditioner compressor, the calculated value of the winding temperature is more accurate.
