How the model reads against DRI's data

Total energy recovery wheels against their maker's own tables: the sensible-and-latent exchanger, both its efficiencies read off face-velocity curves (a latent one that falls with velocity, humidityEffectivenessCurve)

71 listings (36 MS-200, 35 MS-270A) at 9 velocities and 2 rating conditions: 1 278 solves, each filled from the catalog by its reference

the solve reads the printed sensible effectiveness exactly on the streams' capacity rates — the model's own definition, which reads its curve on the smaller one, so this holds the face velocity each curve is read at, not the physics — and the printed latent within a point at every velocity (the MS-270A's listings carry its winter row, a point above its summer one). Through the outlet enthalpy it reads every printed total within a point: worst −0.73 (summer) and +0.54 (winter) points on the MS-200, +0.47 and −0.77 on the MS-270A — whose summer latent row would miss its winter total by 1.11 at 3.5 m/s, which is why the winter row is listed. Not within a point on the standard's definition: on the mass flows alone, AHRI 1060's form, the summer sensible reads up to 1.15 points under the printed figure, and more than a point under at 7 of the 18 summer cells (the MS-200 at 1 and 1.5 m/s, the MS-270A at 1 to 3 m/s) — the humid outdoor air's specific heat against the drier return's, 1.28 % — while every winter cell reads exactly. Which definition a listed core should read is open, and recorded with the data. Not carried: the printed pressure drop — 74 to 241 Pa from 1 to 5 m/s on the MS-200, 76 to 325 on the MS-270A, where a core reads the model's default of 38 to 938 Pa — and the rotor's drive motor (0.09 to 1.1 kW)

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.
