Anyone know where I can find info on heat pumps with more than one compressor? There are models with 2 compressors which come on independently depending on load. I wonder how they are plumbed together: just plain parallel, or with some complicated valves?

Googling shows that often "dual heat pump" mean either a split (both heating and cooling) or a heat pump assisted by an electric/gas heater.
