Abstract: Based on big data analysis, analyzes the problems of excess capacity and low efficiency in low-load household multi-line operation. By optimizing the volume ratio, pump structure, switching mechanism and other aspects of variable-volume compressor, optimizes the motor groove pole matching and winding mode, and combines winding switching technology, inverter electric control optimization and other technologies. Reduce the friction power consumption, leakage loss, exhaust resistance of the compressor, improve the low frequency efficiency of the motor, reduce the frequency converter control loss, thus expanding the minimum cold output, greatly improve the low frequency energy efficiency of the compressor, applied to the home multi-line system can make the low load energy efficiency increased by 20%.
