AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 30.0 K superheat and 0.0 K subcooling; the solver corrects them to the operating superheat and subcooling. Envelope: the manufacturer's 5-sided polygon. It publishes 3 part-load steps (AHRI 540 §5.3.3), which the solver interpolates between. 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.

| Embraco hermetic and variable-capacity compressor maps, fitted from the maker's published tables | 1,283 maps from 815 models (R134a 518, R600a 315, R290 285, R404A 141, R22 11, R1234yf 10, R422D 2, R502 1); 178 variable-capacity models with a table per speed | fitted at the order each table's levels determine (three condensing levels: quadratic in tc), the tables are reproduced at a median RMS of 0.08 % (p90 0.20 %); every map reads the standard's own rating point within 0.08 % at the median and 0.4 % at the ninetieth percentile; every carried flow set closes the identity once the rating's own return-gas and liquid temperatures are read off the node (ASHRAE rates with the liquid at 32.2 °C, 22 K under the condenser). 72 tables withheld and listed by reason: blend groups published as one table, variable-capacity models with fewer than three speeds tabulated, three with a COP under 0.5 at the rating point, three duplicates |
