Cooling system having an inverter for controlling a compressor cooled by a fluid of the system and related process

摘要

In a cooling system, the compressor is controlled by means of a frequency converter (inverter) (36) on the compressor motor (14). For cooling the inverter, a fluid already present in the system, such as coolant (circuit 40, 44), or cooling fluid for the condenser, or user fluid cooled at the evaporator is used.
