Hitachi's 20 HP Set Free outdoor unit as this model runs it: two catalog R410A inverter scrolls behind an air-cooled condenser, modulated to the rated 56.0 kW the way the control runs it. Hitachi publishes the capacity grid — 56.0 kW from 25 to 35 °C outdoor, 52.7 at 40 — and the power input at the rating point only, 15.64 kW (EER 3.58), which this machine draws within 1 %; the capacity is reached at every published temperature. Modelled from the maker's published data — not verified by the manufacturer. Published as an example; the figures below are solved from this model.
