R-12 Saturation Pressure At -10 C _top_ Jun 2026

If the temperature were to drop significantly below -10°C (for example, to -30°C), the gauge pressure would eventually drop into a vacuum (negative psig). However, at -10°C, the system remains in positive pressure, making it easier to detect leaks and for the compressor to move gas efficiently.

Consulting the Scribd R-12 Thermodynamic Property Tables reveals several critical values co-existing at this specific saturation point: 0.2191 MPa / 2.191 bar / 31.78 psia Gauge Pressure: 25.1 psig Liquid Specific Volume ( ): Vapor Specific Volume ( ): Latent Heat of Vaporization ( hfgh sub f g end-sub ): Diagnostic Applications in HVACR r-12 saturation pressure at -10 c

If you have access to a pressure-temperature chart for R-12, you can verify the value by looking up the saturation pressure at -10°C. If the temperature were to drop significantly below
