AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 18.0 K superheat and 0.0 K subcooling; the solver corrects them to the operating superheat and subcooling. Envelope: evaporating -12 to 13 °C, condensing 21 to 66 °C (a rectangle). The mass-flow coefficient set is published too, and the solver checks it against the capacity set.

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.
