I'm a bit confused. Can you help clear some things up for me?

I thought that r22/propane and r12/isobutane were kind of equal opposites. The hc's have large latent heat but small density, the fc's have small latent heat but high density, when compared to each other. R410a plays the middle, having high density and medium latent heat. When the terms are combined, R410a comes out a winner at medium-high latent heat-density.

Does this make sense?

Also, you stated the r290 running in the 410a compressor would have reduced capacity versus the nameplate. Would the compressor also be consuming less power in this condition? What ill effects would the compressor running out of its range have besides being underemployed?

I'm speaking ideally here, not practically. Just trying to gain some clarity and straighten out my thoughts on the different refrigerants. The research on the subject isn't exactly in common english.
