Saw yesterday the world first - it should have been the world premiere they said - Zuba Dan of Mitsubsihi Electric.
Constant heating capacity till -25°C (-13°F) (!!), a 20 to 30% higher capacity (forgot the right numbers) then a comparable inverter unit, a heating up time till 45°C (113°F) in 9 minutes where you need 14 minutes now, 50°C (122°F) discharge air in 14 minutes where the other units can go only to a max of 45°C (113°F).
They've done this via 3 EEV's, a power receiver (suction accumulator with a coil in it to subcool the liquid) and an intermediate HE and intermediate injection in the compressor (similar to the freezer scrolls of Copeland)
They made some sort of an external 2 stage with a scroll.
The rather small presentation went very fast and it wasn't allowed to fire some questions.
I know the Belgium owner very well because we live in your youth at 1/2 mile from eah other and he promised he should send me some more information one of these days.
I searched already the net but couldn't find anything.
