RE: compression ratio

What should the compression ratio be on a scroll r410a compressor, I have found information on how to find out what the compression ratio is, but I can’t find any information on what it is actually supposed to be or how to figure it out looking at the manufacture specs. Any info would be great! thanks

Roughly 3:1 or a bit less seems about typical, but like most things, it depends. Pretty much any r410a unit is going to have a readable charge chart on it. I always go by that
