The map across its envelope
AHRI 540 / EN 12900 ten-coefficient polynomials in evaporating and condensing temperature, rated at 38.3 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.
| te / tc °C | Capacity kW | Power kW | COP |
|---|---|---|---|
| -30 / 45 | 1.83 | 1.56 | 1.17 |
| -20 / 45 | 2.77 | 1.70 | 1.63 |
| -10 / 45 | 4.02 | 1.87 | 2.15 |
Conditions across the published envelope, which does not reach the AHRI air-conditioning rating point (7.2/54.4 °C) — the map is not read there. The whole map — every condition, the envelope and the curves — is in the builder: open this machine in the app. It solves any point inside the envelope, and warns past it.
Open this compressor in the app — the compressor-map tab, with its rating at any condition, its envelope, capacity and power lines and curves plotted, and the refrigerant's pressure–temperature chart a click away; or open the builder and pick it from the catalog picker — the solver runs it with the catalog's own figures, at your design point or across a year of weather.

How the model reads against this maker's data
| Invotech scroll maps read from the Invowin selection tool's own database | 1 103 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 |
