65 psi R22 saturation temp is 37.5. Hard to believe it’s cooling the box at that saturation temp, maybe keeping it in the low 40s. Also you have no superheat. I’d expect to find high subcooling.

R22 contains chlorine, while 407C does not. This makes 407C a more environmentally friendly option, as it does not contribute to ozone depletion. Another difference is their boiling points. R22 has a boiling point of -41.5 °C, while 407C has a boiling point of -51.7 °C.The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume. This leads to a low-pressure environment ...The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI). Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30.Unfortunately not all such corners are exactly 90-degrees so the miter joint has to be adapted to fit tightly.

The delta T on the indoor coil will not be helpful in determining a low charge.Example: The air entering the condenser coil is 70 degrees dry bulb, and the condensing temperature is 100 degrees, which corresponds to about 198 psig for r22 refrigerant. This is an example of ambient plus 30 for those that are new to this forum. Lastly, I understand all the variables involved.Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in a R-22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient. This means if it is 50˚ outside, the suction saturation ...If, for example, the discharge temperature were 210˚ with a 150 psi head pressure, a 10 psi suction, and a 50˚ outdoor temperature, this would show an extreme undercharge. Subcool and superheat can still be checked in heat mode, the problem is since there are rarely any set guidelines, it is difficult to tell when the charge is set correctly by …It can replace R22, R417A and R407C with existing oil in system High Ambient and Centrifugal Chillers R-124 100 A1 0 MINERAL OIL or ALKYLBENZENE Similar to R-114 - high ambient air conditioning.

During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on ...From the PT chart, we can read that the pressure of liquid R422D on a 90-degree day is 197.4 psig. Similarly, we can see that the vapor pressure of R422D on a 90-degree is 184.2 psig. Example 7: What Are R422D Pressures On A 95-Degree Day? From the PT chart, we can read that the pressure of liquid R422D on a 95-degree day is 211.8 psig.With clean coils both inside & outside, an inside temperature of 75° with. 50% humidity, I would expect a low side of roughly 70 PSI, and an hi-side pressure of roughly 20-30° above outside ambient temperature. (depending on efficiency of unit) which would correspond to 243-278 PSI.The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume.
