Title:
COMPRESSOR CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/132606
Kind Code:
A1
Abstract:
This compressor control method is for controlling the vibration amplitude of a compressor provided with a motor by using the motor. The compressor is a device driven by the motor, and the compressor control method controls vibration amplitude so that the same is substantially constant in a specific operation area regardless of the load on the motor and regardless of changes in the rotational speed of the motor. On the basis of, for example, data read out from a preset table, the vibration amplitude is controlled so as to be substantially constant regardless of the aforementioned changes
