This should be obvious, but it happens. R410A curves are different from R32 or R454B (future low-GWP replacements). Ensure your calculator is explicitly set to R410A .
Before diving into the calculator itself, it is essential to understand the canvas upon which these calculations are painted: the Pressure-Enthalpy (P-H) diagram. ph diagram r410a calculator
You can click anywhere on the diagram to see the exact temperature and pressure. Hover over the two-phase region to see the quality (e.g., 40% vapor, 60% liquid). This should be obvious, but it happens
