Furthermore, …May 5, 2016 · The SC might be normal , but the normal head for a r410 system w/ a 68* ambient should be closer to 300psi and the normal suction press should be closer to 110psi w/70* IDB. Those p/t's sound more like r22. kdean1, buttwheat liked this post. As others have said it sounds like a TXV and maybe low on juice. On a properly functioning R-22 system running in heat mode in 40-degree weather, the suction pressure tends to be around 40 PSIG. This guideline obviously doesn't work on an R-410A system or any other refrigerant. A more applicable guideline is 20-25˚ suction saturation below outdoor ambient temperature.Temperature (°F): R410A Pressure (psig): -60 °F. 0.9 psig. -55 °F. 1.8 psig. -50 °F. 4.3 psig.The human heart creates a pressure within the circulatory system every time it beats.

The image above is of the Danfoss refrigerant slider app, and it shows that when suction pressure drops below 102 PSIG on an R410a system, the coil hits 32° and will start to freeze. ... Let's say it's 78° in a house on an R410a system, and your suction pressure is 108 PSIG (as shown). Your suction saturation (coil temperature) is 35°. So ...These liquid-line restrictions all cause the evaporator, compressor, and condenser to be starved of refrigerant. This will cause the following symptoms: Low evaporator (suction) pressure; High evaporator and compressor superheats; Low compressor amp draw; Short-cycling on the low-pressure control;The higher pressure, and the fact that R-410A performs very much like a single component refrigerant, provide an opportunity to produce a more compact system with greater efficiency. In addition, R-410A refrigerant allows more suction line pressure drop since it is less sensitive to suction line efficiency losses.Sep 19, 2013 ... This one covers a test of an air conditioner with high return air temperature to determine how high the suction pressure will go. Constants for vapor pressure of saturated vapor (dew point), p g: A = –1.440004 E+00 E = –3.521484 E+00 B = –6.865265 E+00 F = –7.750000 E+00 C = –5.354309 E–01 X o = 2.086902 E–01 D = –3.749023 E+00 Because both pressure and temperature appear in the reduced form in the equation, the same constants can be used for either SI or ... Good Subcooling Value for R-410A: Similar to superheat, the ideal subcooling value for R-410A can vary depending on factors like system design and operating conditions. However, a common target for R-410A systems is to achieve a subcooling value in the range of 8 to 15 degrees Fahrenheit (°F) or approximately 4.4 to 8.3 degrees Celsius (°C).HVAC Technician: Mark Henley. Hi, Even with a different refrigerant you are still looking for the same coil temperature. So if you want a 40 degree indoor coil you will be at 120 PSI on the low side, then say you want a 100 degree condensing temperature ( 80 degree day ) you are looking for 320. The desired high side target pressure will change ...

My very wild guess would be an obstruction somewhere in the coil or suction line. You eliminated every other cause for a high low pressure (Air flow, refrigerant, compressor txv). I would try touching and observing the piping for any sudden change in temperature. Student here, so take this with a grain of salt. 2.
