Compressor — R454C compressor with a 10-coefficient AHRI 540 map.
A Copeland listing, from the manufacturer's published data.

| Refrigerant | R454C |
| Performance data | AHRI 540 / EN 12900 10-coefficient map |
| Reference superheat / subcool | 26.4 / 0.0 K |
AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 26.4 K superheat and 0.0 K subcooling; the solver corrects them to the operating superheat and subcooling. Envelope: the manufacturer's 6-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.

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