Turns out it was low on R22. I thought it had the same issue last year, but in fact it was 2 years ago that it needed a charge. So, it has a small leak somewhere. The rip-off company charged me $350 for 2 lbs of R22. The suction side was at 40 psi yesterday and he brought it up to 60 psi. It was cool out, about 65 degrees.The range of low side pressure for the R404 is nearby 20 psig in the usual case, and the inlet temperature of the compressor is 25° C approx. For the safe operation of a system with R404 refrigerant, the recommended superheat should be in the range of 20° C to 30° C.

With low side blue gauge on the suction line service port, we measured 130 psi pressure that correlates (according to R-410A PT chart) to about 45°F. The clamp-on thermometer shows that the saturated refrigerant temperature is 56°F. Here’s how to calculate superheat for this system: Superheat (R-410A) = 56°F – 45°F = 11°F

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.Jun 29, 2010 · You asked for the temperartures of the high side line and the low side line as they leave/return to the condensing unit. The high side line tempersture was about 90 degrees F and the low side line was about 60 degrees F. This unit is a 1990 conventional A/C system. Maybe after 20 years of good service, I should not be trying to repair the problem.

I just installed a new compressor and after charging i'm getting the same reading on both high side and low side right at about 60 on my gadges for an old rheem classic that takes r22 please help I need some help. Reply.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 ...An R-22 evaporator running at 40F saturation temperature will have a corresponding pressure of 68.5 psig. Should the suction pressure drop below 57 psig, the coil temperature will drop below 32F causing moisture in the air to freeze on it (see Figure 4) causing no end of trouble. A R-410A evaporator running below 100 psig will freeze-up just ...Superheat was 30 degrees and I brought it down to 10 degrees superheat. Suction pressure at this time was 70 psi and high side was 300 psi and high side needle on gauge was fluttering between approx 300 and 290 psi. Outdoor ambient temperature was 85 degrees. My question is - why is my pressure so high for an R22 system and why is the.And to add, the suction on the unit with the low high side pressure is high, about 100 psig. And the suction on the unit with the high pressure high side is normal and super heat is correct but the subcooling is way off. The compressor's not running on the 100 psi low/100 psi high unit and the other is probably overcharged.

Replaced an A/C unit for a neighbor yesterday. Everything went fine, until we went to balance out the system. The liquid pressure held at 165 no matter what we did, and the vapor pressure kept dropping down to 0. We tried adding freon, and tried taking out freon, but nothing made a difference.if the system has a liquid line or king valve you can charge into the liquid line. if not go to the suction like before. it is'nt always possible to do, charging into high side is fine, but at a point you will have to switch over to the low side.

Psig is equal to psis at sea level (14.7 psi). Psig is equal to psia – 14.7 at sea level. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi.R410A is a 50:50 mixture by weight of R32 and R125. Temperature glide is very small (less than 0.17K).
