The map across its envelope

AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 10.0 K superheat and 0.0 K subcooling; the solver corrects them to the operating superheat and subcooling. Envelope: not published — the map is used unbounded.

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.
