R134a will boil at what temperature at 150 psi?

R134a’s boiling point at a given pressure is the saturation temperature for that pressure. In HVAC practice, when the refrigerant is at a specific pressure, the temperature at which it will boil equals the saturation temperature for that pressure. For 150 psi, the saturation temperature of R134a is about 112 degrees Fahrenheit (roughly 44°C). So at that pressure, R134a will boil at around 112°F. The other temperatures would correspond to different pressures on the R134a pressure–temperature chart.
