R410A Systems Run at a Different Pressure. Compared to an R22 system, an R410A air conditioner runs at a higher pressure. These systems operate at about 130 pounds per square inch (psi). ... This will contaminate the system, and the R22 will not evaporate under the higher suction pressure that R410A requires. An HVAC System …The high side guage was connected to the liquid line. Static, both guages are 160 psig. When the unit ran, BOTH guages dropped to about 130. The high side was perhaps 2-5 higher. The amp draw at the compressor was 8.6 RLA out of a 22.1 suggest maximum on the equipment sticker.

Never install suction- line filter drier in the liquid- line of an R-410A system.! CAUTION 7. If suction-line filter drier was installed for system clean up, operate system for 10 hr. Monitor pressure drop across drier. If pressure drop exceeds 3 psig, replace suction-line and liquid-line filter driers. Be sure to purge system with dry nitrogen ...Many servicemen experience service calls where the compressor has both a low head pressure and a high suction pressure. Often, the refrigeration equipment is still running, but the product temperature is suffering about 7 to 10°F. These calls are tough to handle because the compressor is still cooling, but not cooling to its rated capacity.The blue hose connects to the service port on the unit and then the yellow hose connects to your vacuum pump. The blue hose is 5/16 in. ready to connect to the outdoor unit. The yellow is 1/4 in. for most vacuum pumps. The depicted valve isolates the gauge itself. This gauge also comes with a diagram on the packaging box.The internal pressure relief valve is located between the high and low side of the compressor. It is designed to open when the discharge-to-suction pressure differential exceeds 550 to 625 psid (38-43 bar). When the valve opens, hot discharge gas is routed back into the area of the motor protector to cause a trip.

Suction Temp: 55.4*F.What should my superheat be on a 410a system? For most systems, 20F to 25F should be measured near the compressor and 10F at the evaporator. The system has 10F of superheat if the pressure is 45 psi and the temp is 32F. ... Read and record the suction pressure. Place a digital temperature probe against the suction line near the …R410A systems are much less forgiving, and the only way to get a perfectly charged system is with superheat and subcooling probes. Nonetheless, the low-pressure side should read between 102 and 145 PSI. Anything below this will cause the refrigerant and lines to freeze up. ... Instead, it measures the indoor air handler's suction pressure …Refrigerant Type R-410A R-410A R-410A R-410A R-410A R-410A R-410A Refrigerant Charge (limit) lbs 13 13 13 17 17 17 17 Oil Type Trane OIL00079 (qt)/OIL00080 (gal) Oil Charge oz 101 101 101 88 112 112 112 Suction Fitting Connection Brazed Brazed Brazed Brazed Brazed Brazed Brazed Suction Fitting (ODF) in 1.125 1.125 1.125 1.375 1.375 …Theoretical calculations reveal that at the above high-temperature cooling conditions, a 2-psi suction pressure drop produces about 2% loss of efficiency and 2.4% loss of capacity in an R-22 system. But in an R-410A system, the suction pressure drop can be allowed to go as high as 3.1 psi before the same losses in performance are seen.For air conditioning system, R22 pressure in discharge is250psi and suction in67psi. But for R410A pressure will be more higher that R22. So what pressure is normal for air-conditioning systems. Besides that normal R22 compressor can replace with R410A. by Mohammed Awais haji Latif.Take the suction pressure and use the pressure/temperature chart to convert it to temperature. Let’s say the suction pressure is 60(Psi) which converts to 34F. And assuming that the suction line temperature is 44F. Then to get superheat we just get the difference between the two temperature readings. In this case, we have 10F of superheat. Forane 410A Pressure Temperature Chart. Saturation Pressure-Temperature Data for R-410A (psig)*. pressure relief for R-410A will open at 550-625 psig. Suction and discharged pressure are 40% to 70% greater than R-22 and the discharge temperature of R-410A is lower due to its higher vapor heat capacity. Never heat an R-410A cylinder over 125ºF. • The high-pressure switch will open at 610 psig (plus or minus 10 psig), andJun 6, 2020 ...

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 use the R-410A PT chart to adequately calculate the superheat, total superheat, and subcooling temperatures.The internal pressure relief valve is located between the high and low side of the compressor. It is designed to open when the discharge-to-suction pressure differential exceeds 550 to 625 psid (38-43 bar). When the valve opens, hot discharge gas is routed back into the area of the motor protector to cause a trip.With 410a heat pumps is there a recommended suction pressure. For example with R22 air-con systems I always aim for 400 suction and 1500 discharge and similar with 407c systems. I have been told to aim for round the 100 psi/700kpa mark with is about 0 degree C Was just curious for fault finding purposes. Cheers in advance, chris. What should my normal operating pressures on 410a systems be? R410a suction pressure may be around 120psi, and R410a head pressure may be anywhere from 225psi to 350psi. Many conditions could apply here, there’s absolutely ‘no’ set point pressure for 410a, r22, or anything else. Educate yourself on whats going on in the heat transfer process.
