For on-site use, we include a printable R134A PT chart in PDF form at the end of the article. To help everybody out, we have explained some examples about what is the 134A pressure on 75°F, 80°F, 90°F, and 100°F days below the PT chart for R134A.
Printable PDF. Temperature (°F): Temperature (°C): R134A Pressure (psig): -49°F. -45.0°C.
• Use gauges to determine the pressure at the evaporator coil outlet, and a thermometer to get the actual temperature at the same point. Example: Find the superheat on a system which uses Solstice® N40 (R-448A) when the pressure at the evaporator outlet reads 40 psig and your surface thermometer reads 26°F
