> The trick is that air compressor is attached to a big vibration damping weight, mounted on big springs, which are mounted into an oil filled heavy steel box, which is itself mounted onto rubber feet

So easy... If it was that easy, it would have already been done, but...

1) compressor are maybe 100lb of solid cast steel

2) owners need to fix mechanical wear, not simply "replace the whole thing" - head gasket fails, gauges fails, hose leak (think thermal expansion / contraction), oil need to be changed, etc.

3) refrigerator system are sealed, air compressor need to pull air from the outside (ie. it can be DIRTY), which means lot of the noise actually come from the intake
