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. A tyre pressure monitoring system (TPMS) uses either a direct sensor inside your valve stem or a combination of both software and other existing sensors in your vehicle to let you know when your tyre pressure is outside a safe range of pressures. If the pressure falls below a manufacturers specified limit (usually 25% of recommended pressure) an …R-410A systems operate at higher pressures than standard R-22 systems.

Search Search is the most efficient way to navigate the Engineering ToolBox.407C Pressures vs R22: An In-Depth Analysis. The pressure at which 407C and R22 work is one of the primary differences. R22 has a higher pressure than 407C, which indicates it takes more energy to compress and circulate. This can result in increased operational costs, and in certain cases, a shorter equipment lifespan.Already Tried: EPA certified, added some refrigerant. High side reads about 250 give or take at 90 degrees ambient temperature. Low side reads 43. Using farthest outside scale on gauge. Answered in 3 minutes by: HVAC Technician: Bart Jay. generally it should be around 225 on the high side and near 70 on the low.Let’s use the target superheat formula and calculate this manually: Target Superheat (R-410A) = (3 × 69°F – 80°F – 105°F) / 2 = 11.0°F. We see that the target superheat for R-410A refrigerant in this system is 11°F. You can use the target superheat calculator above to get to this result much quicker.The R-410A has about 40 percent less heat-carrying capacity than the R-22. This causes the reduction of the replacement between the two different compressors. If an R-22 compressor has R-410A refrigerant put into the system, the motors will overload and burn out. The overloading can also cause the motor to start tripping the breaker, shutting ...The pressure-enthalpy chart, as shown in Fig. 2, displays all the pertinent properties for a given refrigerant (in this example R22).
