Running pressures for 410a.

I am wondering what the high and low pressures should be in a 3-ton 410a refrigerant AC system. The installer seemed - Answered by a verified HVAC Technician ... at 90F outside the system should be running 391 psig head pressure, and 107 psig suction pressure BUT ONLY IF THE HOUSE IS COOLED BELOW 73F.Continue the process until the system has been determined to be leak-free. Connect the vapor-line and liquid-line pressure taps to a vacuum pump and micron meter. This step is also almost always omitted. Evacuate the refrigerant lines and indoor coil to at least 350 microns. Close off the valve to the vacuum pump and observe the micron meter.The only down side mentioned was the internal overload would not trip on high pressure for 407c because it would not achieve the 410A pressures. Sent from my iPhone using Tapatalk Reply . 04-22-2018, 10:41 AM #4. ... the capacity of a R410A compressor running with R22 would be about 66% of the rated capacity with R410A at the same conditions ...In this troubleshooting situation a technician has responded to a complaint of "not cooling" on a six-year-old R-410A split system that employs an upflow gas furnace indoor air handler and a condensing unit that sits on the ground, and there is less than 20 feet of connecting tubing. An example of this piping configuration is shown in Figure 1.Saturation Pressure-Temperature Data for R410A (psig)*. Temp (°F) Pressure. Temp (°C) Temp (°F) Pressure. Temp (°C) Temp (°F)

Refrigerant regulations are changing quickly at the state and federal levels, in order to facilitate a smooth transition away from R-410A to lower-GWP refrigerants. Finding a replacement for R-410A has been challenging, but several alternatives have emerged as top contenders. One of those is the mildly flammable (A2L) refrigerant, R …

Typical Low Side Pressure Range for R410A in the field: 115-120 psi. Typical High Side Pressure Range for R410A in the field: 410-420 psi. By 2025, high Global Warming Potential (GWP) refrigerants with a GWP of over 750, will be banned together with the systems using that gas. R410A has a GWP > 2,000.Furthermore, R-410A exhibits higher cooling capacity and operating pressures than R-22, making it an efficient choice for new equipment specifically designed to handle it. Despite the phase-down slated for 2023 as the industry transitions to newer refrigerants, R-410A continues to be a reliable and trusted refrigerant for a myriad of applications.

So we replace the compressor (same model #), replace the liquid line filter dryer, and evacuate to 500 microns. I weigh the charge in per the manual = unit's orignal charge + addl ounces per foot of lineset - total of 5# 6 oz. Start unit up, damn it, looks wrong immediatelY: Suction: 149.5 psi. Suction Temp: 55.4*F.Argument #1: Pressure. Tube-side materials in R-410A coils need to be thicker due to the higher operating pressures associated with R-410A relative to R-22. We’re not arguing that there’s not a difference in operating pressure between the two. There is – roughly 130 PSI for R-410A evaporators compared to about 70 for R-22.Temperature and pressure chart for refrigerants R22, R410A, R12, R134A, R401A, R409A, R502, R404A, R507A, R408A and R402A. ... Temperature and pressure diagram for constant boiling refrigerants - imperial and SI units. Search Search is the most efficient way to navigate the Engineering ToolBox.On quite a few systems, you can get your head pressure on the liquid line, but some systems may require you to connect to the discharge line to check the head pressure. A common rule of thumb is the 100-degrees over ambient rule; the temperature of the discharge line on a running system should be 100-110 degrees above the outdoor air temperature.

Failure to use R-410A approved service equipment could result in standard equipment exploding under R-410A higher pressure which could result in death or serious injury. ...

High side pressure fluctuates on new system. I just installed a new Goodman 13SEER 2.5Ton R410a (scroll) fixed orifice system with new air handler. Correct oriface was installed. Out side temp is 93F indoor is 73F. Low side pressue fluctuated 132-136psi. Low side temp is 58.6F giving me a superheat of 17.4. Calculated super heat is 14.One such substitute that has gained widespread acceptance is R410A, a hydrofluorocarbon (HFC) blend. Unlike R22, R410A does not contribute to ozone depletion and has a lower GWP. This makes it an attractive choice for manufacturers who want to comply with environmental regulations while maintaining the efficiency and performance of HVAC systems.This is where our friend R-410A came into play. New machines from 2010 and onwards were banned from using R-22. Instead, they were outfitted with R-410A.

What is the higher pressure of R-410A? Normally R-22 operating system typically have a high-side (discharge) pressure of 260 psig and low-side (suction) pressure of 76 psig, while a normally R-410A operating system have a high-side (discharge) pressure of 418 psig and low-side (suction) pressure of 130 psig at 45°F/7.2℃.

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.

R32 has a GWP of 675, approximately 70% lower than the GWP of R410A, which is 2088. Due to its single-component nature, R32 heat pumps use 20% less refrigerant than R410A heat pumps. Consequently, their operational costs are lower. R410A refrigerant cannot be reclaimed like R32, as the former is a blend.A compressor that uses R-410A refrigerant has more pressure pushing through the tubes of the system than the R-22 compressor.
