Charging Chart For R22 - 5) if more than 5 degrees over, add charge to decrease line temperature. Pressure for all temperatures of this refrigerant. Remove refrigerant charge if the refrigerant liquid pressure is above the corrected chart value. Web with this r22 pt chart, you can check what pressure r22 refrigerant is at all relevant temperatures. The following example pressures are based on rules of thumb that get you in the right ballpark if no charging chart is at hand. I show why we measure pressures and tempera.
These are currently the three most widely used refrigerants on the market today for hvac applications in residential and commercial use. You will find the chart that summarizes all total superheats further on. About 70 psi at 85 f. Pressure for all temperatures of this refrigerant. Remove refrigerant charge if the refrigerant liquid pressure is above the corrected chart value.
To charge a fixed metering device system (piston) you must use superheat. Remove refrigerant charge if the refrigerant liquid pressure is above the corrected chart value. We have a low and high operating pressure for r22. Normal operating pressures for r22 are between 260 psig (at 120°f) and 76 psig (at 45°f). Pressure for all temperatures of this refrigerant.
To charge a fixed metering device system (piston) you must use superheat. It is important to know the range of these pressures in order to understand why and how charging and recovery are performed. Close r22 container valve, disconnect hoses and replace valve caps. Monitoring pressure and temperature, and seeking professional help if unsure, are crucial for a successful and safe r22 air conditioner charging process.
Normal Operating Pressures For R22 Are Between 260 Psig (At 120°F) And 76 Psig (At 45°F).
