"Less intake (suction) pressure, same displacement = less mass flow and lower exhaust (discharge) pressure."
I understood the quoted part above already, thanks for explaining the difference. It seems mass flow is the important factor in the recent posts.
It's funny you mention fridges, with my lower winter house temperature, I'm running 20-30 watts less power through the compressor and seeing longer runtimes(30-45 mins depending on temp versus 10 mins in the summer). ..but with the lower ambient temperature the refrigerator is running far less often, I did have to max the freezer air valve diverter since the fridge needs less cooling. Using about 500wh daily with the side-by-side non-energy star fridge in my cold house.
