What are normal pressures for R-22?
What are normal pressures for R-22?
R22 gauge pressure is 10.9 bar or 158.2 psi. High side pressure typically varies by equipment and metering controls.
What should R-22 pressures be on a 70 degree day?
If the outdoor temperature is 70°F, a refrigerant bottle outside would have a pressure of roughly 201 PSIG. If the outdoor temperature is 110°F, a refrigerant bottle outside would have a pressure of roughly 366 PSIG.

What should the high and low side pressures be for R-410A?
A normally operating R-410A system with the same condensation temperature of 120 degrees and a 45 degree evaporator saturation temperature will have a high side pressure of 418 psig and a low side pressure of 130 psig.
What pressure should r410a run at?
For R-410A, a working pressure capability of at least 400 psi is recommended (this includes recovery cylinders). Standard DOT recovery cylinders rated for 350 psi should not be used.
What pressure should R134a run at?
22 pounds per square inch
For normal running pressures in the R134a system, at the lowest temperature, the coil should run at 22 pounds per square inch that is 45-20, 25 degrees Fahrenheit. While at the highest temperature it should be 57 pounds per square inches that is 60-20,40 degrees Fahrenheit.
Are 407C and R22 pressures the same?
(10) informed that R407C had higher pressures than R22 with discharge pressure of R22 being at 2193 kPa for the lower outdoor conditions and 2784 kPa for the higher outdoor conditions. For all operating conditions, the discharge pressure of R-407C is varied in the range 11-13% higher than R22.
What temp is R22?
The lower critical temperature of R410A versus that of R22 (70.1 °C (158.1 °F) vs. 96.2 °C (205.1 °F)) indicates that degradation of performance at high ambient temperature should be greater for R410A than R22.
How can you tell if R22 is low?
7 Signs Your AC Unit is Low on Refrigerant
- It takes a long time for your home to cool off.
- Vents are not blowing cool air.
- The temperature you set is never reached.
- Your electric bill is higher than normal.
- Ice on refrigerant lines.
- Water leaking around heater.
- Hissing or bubbling noise.
What happened to R-22 refrigerant?
Taking R-22’s place is the HFC refrigerant blend known as R-410A, our Puron. As I write this article, in 2019, there are still thousands of R-22 machines out there, but they are a dying breed and within the next ten to twenty years R-22 will be as rare to find as R-12 is today.
What is the temperature of the refrigerant in the evaporator?
The temperature of the refrigerant in the evaporator is about 4°C to 7°C (8°F to 12°F) colder than the evaporator when the compressor isrunning. The temperature of the refrigerant in the evaporator is the same as the evaporator temperature when the compressor is notrunning.
Why was R-22 phased out?
Along with air conditioning it was also used in chillers, ice rinks, and many other applications. It was in the 1980’s that it was discovered that R-22 was damaging the Ozone layer with the chlorine that it contained. In order to correct this R-22 was phased out across the world.
