Title:
VARIABLE CAPACITY COMPRESSOR OPERATION MODE DETERMINATION METHOD, APPARATUS, VARIABLE CAPACITY COMPRESSOR, AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/077790
Kind Code:
A1
Abstract:
A variable capacity compressor operation mode determination method, apparatus, variable capacity compressor, and air conditioner. The variable capacity compressor operation mode determination method comprises: before switching the operation mode of a compressor, detecting the current electrical current value, A1, of the compressor; switching the operation mode of the compressor, and after a pre-set duration, detecting the current electrical current value, A2, of the compressor; comparing A1 and A2, and if the ratio value between A1 and A2 satisfy a pre-set condition, it is determined that the operation mode switching for the compressor is successful, otherwise, it is determined that the operation mode switching for the compressor has failed. The present determination method performs comparison using the ratio value between the electrical current values of the compressor before and after operation mode switching, and can therefore accurately determine whether the operation mode switching for the compressor is successful, thereby optimizing the utilization methods of the compressor.
