I'm seriously thinking to set a rack of compressors for supermarket refrigeration with two or more on-off compressors and one frequency inverter driven. This due to get always a good P.I.D. loop, coupled with elecronic expansion valves and R404a or R507 gas for both the mid and low range purpose.
Untill now i just found out hermetic or screw compressors on the european market, but i don't love them all so much.
Has anyone experience on reciprocating semi-hermetic compressors inverter equipped?
Any advice on it and how to choose, employ or run them?
Is it a good thing to buy a normal compressor and to feed it throw a commercial frequency inverter? I think it might be better to buy both the compressor and the inverter from the same producer, at least for the warranty.
Problems with lubrication and gas flow in case of reduced speed?
Thank you all, guys.
