Set of compressors and method for controlling a set of compressors

摘要

The speed control method involves providing a frequency converter that is alternately associated with each of the compressors at least temporarily. In the event of four or more compressors being present, two or more frequency converters are provided and each is alternately associated with at least two compressors. The compressors are identical. Independent claims are also included for the following: a compressor system with at least two compressors driven by electric motors.
