if you have fan speed control keeping a constant head pressure

then as suction pressure rise's compressor work is lowered

so maybe a miss print

unless the R410a has fan speed control

and the R22 does not

CM, it was a question that only came about because I have an old ASHP that has a good R22 pot and I am looking for the right one to use in my combi solar/evap project.

If you just look at the performance data for the R22 pot, it would seem to be the opposite of what you said (unless I'm full of it, which is entirely possible)

The question assumes all things being equal between the two.
