Built in this model on the maker's published performance grid and validated against it — not verified by Samsung. Each page names its source and says so.
| Samsung DVM S AM200FXVAGH/EU (20 HP, 56 kW) — modelled | Samsung VRF Technical Data Book, DVM S outdoor units for Europe (R410A, 50 Hz), ver. 1.3 — AM200FXVAGH/EU capacity table (H/P standard), 100 % combination at 19 °C indoor wet bulb (docs/samsung-vrf-source.json) |
| Heat-pump frost/defrost derate | 43, from five makers | RMS 0.023, where the makers stand 0.029 from each other at the forty temperatures they share — the one generic curve is closer to each of them than they are to one another, and none is served much worse than any other (0.019–0.028 apiece). The EnergyPlus model this replaced had the shape inverted (deepest just below its 5 °C cutoff, then a 29-point step across it) and read up to 0.15 low |
| Three-pipe heat recovery: SCHE, and what the outdoor coil sees | three configurations (cooling-led, heating-led, balanced) in hvac-core; the Meguro office's 635 mixed-mode hours a year | with both sides pinned by their coils, the outdoor coil rejects (or absorbs) exactly the larger side less the recovered duty, both sides export once each, and SCHE = COP_c + COP_h by identity on a map where qc = qe + hrf·P — not COP_c + COP_h − 1, which the first draft asserted from memory and the probe corrected. On the office's Tokyo year the three-pipe unit serves both directions on 567 hours and takes the north room's unmet heating from 25 hours to 1, at electricity flat to 0.1 %: the recovered loads are trickles at the machine's floor, so what recovery buys here is the hour, not the kilowatt-hour |
| VRF (multi-split): capacity against the connected-capacity ratio | eight makers | they agree on a two-regime law — exactly linear below 100 % connection, saturating above it by +2 to +8 % at 130 %, with Samsung allowing no credit above 130 % — and the model reproduces both without a correction term: below full connection each indoor coil caps its own take, above it the outdoor unit's map is the ceiling (+0 %, the conservative end of the band). The standards themselves rate only at unity connection (±5 %) |
| Samsung DVM S AM200FXVAGH/EU (20 HP), modelled — the whole machine against Samsung's published grid | 8 | modulated to Samsung's capacity, the machine draws −1 to +4 % of Samsung's power input, the compressor at 0.67–0.81 of full output; the same graph reads +1 to +4 % against Midea's 20 HP grid |

Listed from published data with the source named on every entry; a listing's figures are the manufacturer's, the model that runs them is ours. Solver results never depend on who has claimed what.
