Copper Coil Overview
R-134a US Overview Chart — Copper Coil Overview
A copper coil fills the rust-colored heading above a white strip of reference-state values and a warm-toned overview table.
Use this chart to look up the saturation pressure of R-134a from a Fahrenheit temperature, then compare the equivalent Celsius reading on the same row. The 5°F spacing gives a broad overview rather than the finer steps of the detailed edition. This copper coil overview version covers -40 to 180°F in 5°F steps.
The strip above the table highlights the same reference state in temperature, psi gauge pressure, and bar gauge pressure for a quick unit comparison. The 45 listed reference points use Fahrenheit, Celsius, psi gauge, bar gauge.

The PDF preserves the one-page print layout. The matching Image is a full-resolution WebP rendering. These are finished reference sheets with fixed data and illustrations.
Gauge pressure uses a 101.325 kPa atmospheric reference. Saturation values describe the refrigerant relationship; equipment instructions determine operating and charging targets.
