The map across its envelope

AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 11.0 K superheat and 8.3 K subcooling; the solver corrects them to the operating superheat and subcooling. Envelope: the manufacturer's 6-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.

How the model reads against this maker's data

Invotech scroll maps read from the Invowin selection tool's own database1 103 maps (R22, R410A, R404A, R407C, R134a, R448A, R449A, R452A, R455A, R454C; 50 and 60 Hz)nomenclature median +0.5 %, worst 5.1 %; the tool's SI cubics carried exactly, ×1000 and ÷3600; 990 flow sets close within 15 %, 113 whole low-temperature families sit at a flat 0.76–0.85 of Q/Δh and ship without their flow set, each recorded with its ratio

From the validation page; every row is held by a test.

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.
