The minimum, recommended low pressure cut-out switch settings for heat pumps application are 20 psig (1.4 bar) for R410A and 10 psig (0.7 bar) for R22, R407C and R134a. See AE4-1303 for more information.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. These units use R-410A refrigerant which operates at 50 to 70% higher pressures than R-22. Use only R-410A approved service equipment. Refrigerant cylinders are painted a “Rose” color to indicate the type of refrigerant and may contain a “dip” tube to allow for charging of liquid refrigerant into the sys-tem. Physical Properties: R-410A has an atmospheric boiling point of -62.9°F [-52.7°C] and its saturation pressure at 77°F [25°C] is 224.5 psig. Composition: R-410A is a near-azeotropic mixture of 50% by weight difluoromethane (HFC-32) and 50% by weight pentafluoroethane (HFC-125).

We can now refer to a pressure-temperature (PT) chart to determine the corresponding pressure at 108°F. The Danfoss Ref Tools (previously Refrigerant Slider) app is perfect for this. The liquid line pressure at 108°F saturation temperature is 356.5 PSIG. This screenshot of the Ref Tools app shows the liquid line pressure of R410A at ...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.

As others have said it sounds like a TXV and maybe low on juice.R-410A's higher operating pressures (60-70 percent higher than R-22) mean that contractors and techs are now using gauges designed for 410A. Refrigerant recovery equipment also must be designed for this refrigerant's pressures. R-410A will also produce refrigerant burns more quickly than R-22. Protective equipment is a vital part of safe work ...R-410A HFC 72.6-61 691.8 158.3 34.5 67.74 0.261 116.8 0.3948 0.1953 0 2088 A1 0.2 Refrigerant Reference Guide 43 5th Edition 2010 R-410A Technical Guidelines Applications: Air conditioning equipment and heat pumps.

I am charging my heat pump it is an r410a and its about 90 degrees outside i have gotten the low side up from about 100psi to 130 and the high side from around 300psi to 340-50 is this about right what should my pressures be. The 410a part of the gauge is reading 44 low and 106 for high.Adding Freon to heat pump during the heat mode, Carrier Unit, winter season maintenance, 2018 HVAC TECHNICIANEco-Safe R-410A Refrigerant & MrCool. August 10, 2016. By MR COOL. Eco-safe R-410A refrigerant is the new standard for American air conditioners and heat pumps. As you might expect, it’s also the main refrigerant we use here at MrCool. The government, of course, required companies like us to adopt refrigerants like R-410A, but do you know why?

One for heating and one for cooling. At a given outdoor ambient, indoor wetbulb and dry bulb, the suction and discharge pressures should intersect on a graph at specific temp readings along a curve on the graph. Also, as Houston said, there should be a desired subcooling reading at the outdoor unit.The R410A PT chart can be used to answer questions like: What are normal operating pressures for 410A? What is the pressure of r410a at 72 degrees Fahrenheit? What should gauge read for 410A? You can also …Feb 20, 2023 ... The operating pressure of 410A on an 85 degree day is 254.6 psig.

On a properly functioning R-22 system running in heat mode in 40-degree weather, the suction pressure tends to be around 40 PSIG.
