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: evaporating -40 to -12 °C, condensing 4 to 60 °C (a rectangle). The mass-flow coefficient set is published too, and the solver checks it against the capacity set.
