AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 11.1 K superheat and 8.3 K subcooling; the solver corrects them to the operating superheat and subcooling. Envelope: the manufacturer's 5-sided polygon. The mass-flow coefficient set is published too, and the solver checks it against the capacity set.

Points on a 10 K grid inside the published envelope; the builder solves any point in it, and warns past it.
Open the builder and pick this listing from the catalog picker — the solver runs it with the catalog's own figures, at your design point or across a year of weather.
| Compressor maps converted from the vendor's own rating database | 5 452 maps (4 776 of the worldwide publication, 676 of the Asia and China publications listed for their region) | every basis median within 3.1 % of the nomenclature; the vendor's polynomial substituted exactly, never refitted; each map's superheat and subcooling reference read off its own rating row (the ZW heat pumps at 5 K, the ZH/YH at 10 K, the Discus at 25 K, the small hermetics at a 40 °F return gas) |
| The compressor map's superheat/subcooling correction — AHRI-rated maps read at EN 12900 conditions | 99 R410A (13 models) + 22 R407C + 35 R134a | the corrected map reads the guide's capacity at −0.1 % mean / 1.0 % RMS on R410A, flat across evaporating temperature, every model within ±1.6 %; R407C nominal +0.3 % / 1.6 %; R134a +1.5 % / 1.8 %. The uncorrected polynomial reads +9 to +11 %. The R404A refrigeration scrolls, rated at a return gas rather than a superheat, read the guide's 20 °C return-gas tables at +0.7 % / 1.5 % from −15 to −5 °C (88 points) — there the correction is a one-per-cent matter either way. Not held: the heat-pump scrolls, for which the guide prints heating capacity — and one R407C row (ZRD72KCE) disagrees with its map by a quarter and is recorded as a catalogue fault |
