Abstract
A system for operational acoustic optimization of a variable speed compressor () includes a motor (), a frequency inverter (), and a control block (). The frequency inverter () is electrically connected to the synchronous motor (), an electrical network (), and the control block (). The control block () is configured to control the speed of the motor () and to establish a first switching frequency (F) and a second switching frequency (F) of the frequency inverter (). The frequency inverter () is configured to start the variable speed compressor () by supplying motor () with a signal () with the first switching frequency (F) for the duration of a time period (T) corresponding to at least one alignment operation period of the motor () and to supply the motor () with a signal () with the second switching frequency (F) after the time period (T).
