Abstract

The unit comprises two compressor motors which can be switched on by means of actuators, e.g. relay, parallel to each other on a frequency converter (6) with variably adjustable frequency. The compressor motors are single phase asynchronous motors (1,2) with two windings (3,4) and a startup mechanisms (5).
