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 and evacuate when replacing filter driers. Continue to monitorWhen connecting gauges, connect to the always-suction port on the low side. 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 ...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.*Red Italics Indicate Inches of Mercury Below Atmospheric Pressure Saturation Pressure-Temperature Data for R507 (psig)*This chart is essential for HVAC technicians as it helps in diagnosing and maintaining air conditioning systems. The chart displays temperature values (in degrees Fahrenheit or Celsius) against pressure values (in pounds per square inch gauge, or PSIG), allowing for accurate adjustments and troubleshooting of HVAC equipment using R-410A ...1. Optimal Cooling. When the low side pressure operates within the recommended range for 410a, your system can efficiently absorb heat from your indoor environment. Any deviation from this range might compromise the cooling efficiency, leaving certain areas less cooled than others. 2.On 85 degrees, find the corresponding values in the 2nd and 3rd column. In this case, The 410a pressures on a 85 degree day are as follows ; Liquid pressure for 410a on a 85 degree day is: 255.4psi. Vapor pressure for 410a on a 85 degree day is: 254.6 psi. Example 2 What should the 410a pressures on a 50, 65, 70 degree day be? On a 50 degree dayThe manual states that the design pressure should be 255/465 psi. The running pressure is about 200 on the fluid line and 150 on the exhaust line. This is what my installer feels like a good pressure. However, the company that sold me the system said that the pressure should be ~100psi on either line.Like R-22, R-410A is nonflammable, but can become combustible if mixed with air at elevated temperature and/or pressure. The required conditions depend on air concentration, pressure, and temperature. Do not mix R-410A with air for leak testing or other purposes. A mixture of R-410A and nitrogen can be used for leak testing.Normal operating temperatures for R-410A systems typically range between 35 to 60 degrees Fahrenheit (1.7 to 15.6°C) for the evaporator coil temperature and 90 to …R410A Pressure Temperature Chart (In Fahrenheit) Printable PDF Temp er atu r e (° F ): R410A P r essu r e (p si g ):-60 ° F 0. 9 psi g-55 ° F 1. 8 psi g-50 ° F 4. 3 psi g-45 ° F 7. 0 psi g-40 ° F 10. 1 psi g-35 ° F 13. 5 psi g-30 ° F 17. 2 psi g-25 ° F 21. 4 psi g-20 ° F 25. 9 psi g-18 ° F 27. 8 psi gSo it gets weighed either way. In Canada you have to be a licensed HVAC technician with an ODP card to get your hands on 22 or 410, so reclaiming and filling with new 410 (if there was a leak) as a DIY project is not really an option. Reply. 07-15-2005, 08:30 AM #8.R-410A, a new refrigerant that has recently been developed, is currently being used in the HVAC/R industry.

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).Like R-22, R-410A is nonflammable, but can become combustible if mixed with air at elevated temperature and/or pressure. The required conditions depend on air concentration, pressure, and temperature. Do not mix R-410A with air for leak testing or other purposes. A mixture of R-410A and nitrogen can be used for leak testing.AZ-20 (R-410A) pressure is about 60% (1.6 times) greater than R-22. Only use servicing equipment and components designed for AZ-20 (R-410A). – Recovery cylinder service pressure rating 400 psig, e.g. DOT 4BA400 and DOT BW400. – Manifold sets must be 800 psig high-side and 250 psig low-side with 550 psig low-side retard.The term gauge signifies that the pressure has been read from a gauge that actually measures the difference between the pressure of the fluid or gas and the pressure of the atmosphere. Psig is equal to psis at sea level (14.7 psi). Psig is equal to psia - 14.7 at sea level. Psia is absolute pressure, which means it is gauge pressure + 14.7 psi.Pressure/Temperature Chart.
