inversor frequency

[Mauro]

hi all

:confused: Which the advantage of the installation of inverter of frequency in compressors of refrigeration?
Does anybody have experience in this type of equipment?

Most here do, most new ac's come with an inverter!

The compressor can go down in performance if the load is low and go up when load increases.

thank you Sanderh

I would like to know if performace of the compressor if keeps, and as it is the return of the oil of the expositors? yours is using very the installation of invertors in the compressors?

[Lowrider]

Oil return is always an issue, aspecially if running at low frequency for a long period, but most manufacturers sorted the problems.

I work on them sometimes, but mostly on chillers from 20kW up to 4MW and they don't have them!!
