It's hot here in AZ - 110 degrees f , i heard teh outside temp affects pressure. Q on my 12 yr old r22 tempstar is 340 psi on high side too much pressure? (75-80 on low). remember, it was 110 outside when i checked system seems to be cooling fine, just not as ice cold as earlier in the summer (PS- the factory tag says Test Pressure …You need at least a 50 degree IWB and 55 degree ODB at minimum to measure superheat accurately. You can block the coil to simulate your ODB target if it's too low, but be careful how much you raise the head pressure or your SH will drop to 0 degrees. Use a superheat charging chart to determine whether or not you can check the charge.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. Sounds likely overcharged. The reason the suction pressure doesn’t change when the solenoid valve closes is because the compressor doesn’t stay ...On gauge, using the farthest outside scale. On the high side, it should be around 225 degrees and near 70 degrees on the low. Also, I’m curious as to what my r22 pressures should be.

The low side pressure with MO99 will be a couple of psi lower than R-22 while the high side (cond) will be slightly higher than R-22. The MO99 retrofit guide has a lot of useful information, including proper setting of superheat and subcool. It seems 15°of SH and 5-7° SC would be adequate.Option B, the air conditioner's refrigerant R-22 at 70 psig and 55 degrees Fahrenheit is superheated, as the temperature is above the saturation temperature for that pressure according to the R-22 PT chart. ... If an air conditioner with refrigerant R-22 has a low-side pressure of 70 psig and a temperature of 55 degrees Fahrenheit, we must ...4.8 (21) The refrigerant R22 has been phased out due to its ozone depleting properties. In order to replace it, manufacturers developed R134a. This new refrigerant was designed to be safer for the environment and better for the ozone layer. R134a is a hydrofluorocarbon (HFC) refrigerant that is commonly used in air conditioning systems. It […]The condenser comes charged with 15 feet of 410A. My install has 40 feet of 3/8" and 7/8" line total --- leaving 25 feet needing additional refrigerant. (Goodman suggest adding .6 oz per foot of liquid line) but that seems to be high. At the present time I am setting at 308 (High Side and 143 Low Side with no charge added beyond the 15 foot ...

An R12 system should have a minimum of 60 psi to avoid freezing. That's with a Fahrenheit of 70-74 degrees Fahrenheit as the ambient temperature. Low and high side pressures should increase as the ambient temperature rises. The high-side pressure on a fully operating system will be around twice the ambient temperature + 50 PSI.We would like to show you a description here but the site won’t allow us.A normally operating R-410A system with the same condensing 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. ...
