Title:
METHOD AND APPARATUS FOR CONTROLLING VARIABLE FREQUENCY COMPRESSOR, VARIABLE FREQUENCY COMPRESSOR, AND TEMPERATURE CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/222564
Kind Code:
A1
Abstract:
A method for controlling a variable frequency compressor. The variable frequency compressor comprises a controller configured to output a frequency waveform required for the operation of the variable frequency compressor. The method comprises: acquiring a target operating frequency of the variable frequency compressor; obtaining a register value of the controller according to a functional equation, wherein the functional equation is obtained on the basis of the correspondence between the register value and the target operating frequency and using the method of least squares; and controlling the variable frequency compressor to operate at a frequency waveform corresponding to the register value. According to the method, the register value of the controller is obtained using the functional equation and the target operating frequency, and the variable frequency compressor is controlled to operate at a frequency waveform corresponding to the register value, so that an actual operating frequency corresponding to the register value is closer to the target operating frequency, thereby improving the control precision of the variable frequency compressor. An apparatus for implementing the method and controlling the variable frequency compressor comprises a variable frequency compressor of an apparatus for controlling the variable frequency compressor, and a temperature control device of the variable frequency compressor.
