IMPIANTO FRIGORIFERO CON INVERTER DI CONTROLLO DEL COMPRESSORE RAFFREDDATO MEDIANTE FLUIDO DELL'IMPIANTO E PROCEDIMENTO

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.
