R22 low side pressure at 70 degrees.

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°FFinal answer: The conditions of an R-22 refrigerant with 70 psig pressure and 55 degrees temperature suggest it is likely in a superheated state, not in a saturated state or a supercritical state.The correct option is b) it is superheated. Explanation: The conditions of refrigerant R-22 with a low-side pressure of 70 psig and a temperature of …Low side should usually be ~70-75 psi at that indoor temp and high side should be 170+psi (depending on how dirty your coil is and seer rating). And while you can't tell exactly how much refrigerant you're down without exact numbers for your system (metering device, indoor wetbulb, dirty coil) you can usually tell if you're low.If you are checking the charge then you need to check it by Sub-cooling (TXV) or Super heat (Piston). If you are doing it any other way you are just guessing. The are to many variables to say what should the reading be with an outside temp of 80. John Wayne once said "Life is tough and it is even tougher if you are stupid".
