AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 23.6 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.
