Blue Phase Folio

R-134a SI Detailed Chart — Blue Phase Folio

A blue liquid layer is visible inside the illustrated vessel above a pale-blue, layered Celsius table.

Use this sheet when you need an R-134a reference at 1°C intervals. Read across a Celsius row to compare gauge pressure in bar with absolute pressure in kPa; those pressure columns use different reference points. This blue phase folio version covers -20 to 60°C in 1°C steps.

The raised paper-style table panel separates the reference rows from the illustration and title above it. The 81 listed reference points use Celsius, bar gauge, kPa absolute.

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.
