Hi friends welcome to the new post. Here we will learn the R410A Pressure-Temperature Chart. R410A is very commonly used refrigerant that is known as AZ-20”, “Genetron R410A”, “Puron. It is patented by Honeywell. It is mostly used freon in AC systems and works as a replacement for R22. Here we will make an R410A Pressure-Temperature Chart that will help you find its working for different temperature ranges. Let’s get started with the R410A Pressure-Temperature Value Chart.

r410a refrigerant characteristics
| Features | Details |
|---|---|
| Boiling point (°C) | −48.5 |
| Liquid density (30 °C), kg/m3 | 1040 |
| Vapour density (30 °C), air=1.0 | 3.0 |
| Vapour pressure at 21.1 °C (MPa) | 1.383 |
What is the normal temperature for R-410A?
The normal working R410A system with similar condensing temperature is 120 degrees and 45 degrees evaporator saturation temperatures come with a high pressure of 418 Psig and a low-pressure side of 130 psig.
What is the ideal pressure for 410A?
The normal range of operation of the low-pressure side of the AC system is about 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A according to conditions.
What temp does R-410A boil at?
The liquid refrigerant in the system is known as R410A and boils at 55.3° Fahrenheit. The boiling point of water is affected by varying pressure so the boiling point of refrigerant changes with applied pressure in the ac system.
What is the evaporator temperature of R-410A?
The normal evaporator pressure value is –40 °C (–40 °F) to –65 °C (–85 °F).
Is 410A high pressure?
R10A works at an average of 480psi to 500psi making it high pressure refrigerant. It is required to explain since working with high pressure can be dangerous.
Which is colder R-22 or 410A?
R410A can cool the room quickly with the use of less energy. Effective operation is an important advantage of R410A. But it works similar way to R22 for absorbing heat to offer cooling. R410 not make rool colder like older refrigerant
What is a good low side pressure for R-410A?
between 102 and 145 PSIG
What is a good superheat for 410A?
Superheat for most systems is about 10F measured at the evaporator; 20°F to 25°F close to the compressor. if the suction pressure is 45 PSi and the suction temperature is 32 F system still comes with 10°F of superheat.
What oil is used with R-410A?
Polyol ester oil (POE oil) is a wax-free synthetic oil used in refrigeration compressors which supported with refrigerants R-134a, R-410A, and R-12.
Is R-410A highly flammable?
R410A is not flammable at ambient temperatue and atmospheric pressure. But it will be combustible if mixed with air under pressure and exposed to strong ignition sources.
How to calculate subcooling 410A?
Check the thermocouple temperatue on a digital thermometer. For this refrigerant pressure and temperature charts can be used for conversion of condenser saturation temperatue. Minus condenser saturation temperature from thermocouple temperature. The result is the amount of subcooling.
Is charging R-410A liquid or gas?
R410A is needed to charge in liquid. According to instructions on a refrigerant cylinder confirm that the cylinder is directed accuralty for charging. Charging as gas can cause refrigerant separation and improper unit working.
How do you calculate superheat for r410a?
The saturation temperature is written on the gauge of the R410A unit by lining up pressure to an accurate refrigerant scale.
Which refrigerant is good R32 or R-410A?
R410A comes with a high VCP that needs larger pipes. So it is not as effective as R32 which has a low VCP. With that R32 comes with a high pressure ratio as compared to R410A. R32 is more effective than R410A.
Which refrigerant is best for AC?
R32 is a balanced refrigerant in the form of Environmental Impact/Energy Efficiency/Safety/Cost-Effectiveness for Stationary Air Conditioners and Heat Pumps.
Can we fill R410A in R32 system?
No R32 is not best for a replacement for R410A and is only used in a system that is made for R32.
How is R-410A made?
R410A is an HFC type of refrigerant made with the use of R-32 and R-125. Its chemical formula is CH₂F₂ + CHF₂CF₃.
