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.
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
R-12 (Dichlorodifluoromethane) is a chlorofluorocarbon (CFC) refrigerant historically widely used in automotive air conditioning, commercial refrigeration, and domestic refrigerators. Although its production was phased out under the Montreal Protocol due to ozone depletion potential (ODP), understanding its thermodynamic properties remains crucial for maintaining legacy systems, retrofitting calculations, and educational purposes.
