Built in this model on the maker's published performance grid and validated against it — not verified by Gree. Each page names its source and says so.
| Gree GMV5 GMV-168WM/B (14 ton, 49 kW) — modelled | Gree GMV5 DC-inverter VRF units technical sales guide (460 V heat pump) — GMV-168WM/B cooling capacity table, 100 % combination at 66.2 °F WB / 80.6 °F DB indoor, total capacity and power input against outdoor dry bulb (docs/gree-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 |
| 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 %) |
| Gree GMV5 GMV-168WM/B (14 ton), modelled — the validated machine scaled to another frame, against Gree's published grid | 8 | every dimension of the 20 HP graph scaled by 49.2/56 at once and modulated to Gree's capacity, the machine draws −4 to +1 % of Gree's power input — nothing re-fitted |
From the validation page; every row is held by a test.
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.
