So, we can assume it will work, right ??
OK, shaft seals. An Auto will run that compressor a whole lot more than a fridge. RIGHT ??
So, shaft seals should last longer, and the Auto compressor runs in a very hostile environment, right ??
So, the fridge will be easier on the compressor, right ??
Down here, electricity is slowly going up in price. One of the illustrious past Presidents, had a Wind Farm put up, on top of one of the highest plateaus. I believe there are 7-8 machines.
He then passed a law that no one else can ever do the same thing, and sell electricity to the Monopoly company, ICE.
Where I live, we have MANY instantaneous "Burps" in the power system, that HAS to create havoc on Electronics, FRIDGES, Water Chillers, etc. Sometimes, this happens several times in a matter of 1-2 minutes. Think someone pulling and closing a big knife switch, several times in that 1-2 minute time span.
Also, there are several farmers that would LOVE to move out on their farms, but, there is no power, and, it would cost several thousand $$$ to put the lines and Transformers in. Some of these guys would like to put in a vacuum type milking machine, and then, need to cool the milk. Others have a water chiller, that resembles the old RC Cola water chiller boxes, where you opened the sliding door and plucked out a nice cool RC Cola, or whatever.
IF these things could be run directly off home produced power, I would have a nice little business going. 1-2 guys have sufficient water to get steady power from Hydro. I need to figure how to maintain a near 60 HZ AC power system for them to run directly off the system, and charge a couple batteries as a dump load.
The others might be able to run DC motors on compressors and vacuum pumps. Then, build a house and run it mostly on DC Voltage.
Other than refrigeration, we are not talking that much load, normally.
