AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 47.2 K superheat and 0.0 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.
