Running pressures for 410a.

The picture below shows a system running on a 85°F day that had 6 ounces of R-410A added. In the picture, the manifold valve to the blue hose is closed so the blue gauge is measuring the pressure inside the running system. The vapor pressure is 118 PSIG and because it is 85°F outside, the R-410A bottle pressure is 254 PSIG.

R-22 system would have a compression ratio of 3.02:1, while the R-410A system would have a compression ratio of 2.98:1. The actual efficiency gains from R-410A are due to its superior thermodynamic values over R-22.SUCTION PRESSURE / EVAP DTD RULE OF THUMB Another common old school rule of thumb is suction pressure should be close to the outdoor temperature in a R-22 system. However, this rule of thumb (obviously) does not work on an R-410A system. A more applicable guideline is 20˚-25˚ suction saturation below outdoor ambient.

Still though... something doesn't sit well with me about all of it. I think I'm going to change the switch for good measure and reclaim/meter in the charge again. According to my PT chart, the static pressure of R410A at 65° is 185psi. I'm guessing that's not what you were asking about, but that's what it is.By contacting an HVAC technician, you can get your AC system's suction pressure back to normal levels.

We'll be glad to come out and take a look at the issue. 1431-183 A/C & Heating proudly serves Round Rock ...I have a 1991 Rheem 2.5 ton A/C and coil. Last summer, it lost all 4 lbs of R-22. I've got several proposals for replacing it with a new compressor and coil using R-410a. All the proposals specify reuse of the existing 3/4" and 3/8" lineset. The suction line has a severe bend, almost to the point of being crimped, just before it enters the outdoor unit …The low-pressure switch setting for a walk-in cooler is designed to protect the compressor from running under low-pressure conditions, which can lead to damage. Typically, the switch is set to cut off the compressor if the pressure drops below 20-25 psi, though this can vary based on the specific system and refrigerant used.However, based on the gas laws you can approximately calculate your difference in saturation pressures. R410a runs between 60% and 70% higher saturation pressure. With a 10% concentration you will have approximately 6-7% higher saturation pressure than normal R22 alone. As it stands, here's what I would do if I made this mistake.

Pressure/temperature relationship. I was discussing some pressures with another tech. He asked me about an r410a unit that the pressures were 125 psig= 43 degrees back pressure over 350psig =107 degrees condensing pressure he says oh that's all out of whack and 350 is to high because when I do my maintenances I usually see 150/275 300 max.I thinks your assuming it was low because of suction pressure. If TXV Charge to sub cooling-- I am thinking your sub cooling was high and you have a restriction or TXV issue. Good point, the stuck TXV would be known by high subcool and high superheat. This would be a tough diagnosis for a beginner tech.

For example, the IPR will open at a pressure of 375 to 450 psig for R-22 systems and a pressure of 550 to 625 psig for R-410A systems. Kramer noted that the suction and discharge pressures are 50 percent to 70 percent greater with R-410A than R-22, but the discharge temperature of R-410A is lower due to its higher vapor heat capacity.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. If you would like to read more about R-410A refrigerant please have a look at our Puron fact sheet. R-410A PT Chart.

This system and house is about 20 years old, and uses R-22. I would like to replace the condenser with an R-410a unit, but I don't know if that is possible with my evaporator. The model of my evaporator is a Rheem RCLB-A036S. The nameplate also says low side test pressure 150PSI. I was not able to find any.

pressure of about 250 psi at an outdoor temperature of 95°F. With R-410A, the same unit will operate under the same conditions with a suction pressure of 118 psi and a discharge pressure of 400 psi, as shown in Figure 1 on the next page. (Note that in most cases, equipment designed for R-22 cannot use R-410A because of this difference in operating
