R-410A Refrigerant Mainframe: Properties, PT Charts, and Field Pressures

The Legacy Standard of High-Pressure Inverter Systems

R-410A (commercially branded as Puron or Suva 410A) remains a cornerstone chemical baseline across millions of residential split ACs and commercial VRF networks globally due to its high volumetric cooling capacity.

In this engineering manual, we publish the complete R-410A Saturation Pressure Sheets and Sizing Parameters. Prime Cool implements these metrics across daily services in Pune.

Technical Profile of R-410A

• Chemical Formula: R-32 / R-125 (50% / 50% pure mass weight split)
• Boiling Point at 1 Atmosphere: −48.5°C
• ASHRAE Flammability Code: A1 (Non-flammable, non-toxic status baseline)
• Global Warming Potential (GWP): 2,088

Saturation Temp (°C)	Pressure (psig)	Pressure (bar g)
−5°C	86.1 psig	5.94 bar
0°C	102.2 psig	7.05 bar
5°C	120.3 psig	8.29 bar
10°C	140.5 psig	9.69 bar
15°C	163.0 psig	11.24 bar
45°C (Indian Peak Condensing)	390.4 psig	26.92 bar

Field Diagnostic Metrics

Because R-410A runs at pressures nearly 60% higher than old legacy R-22 networks, technicians must use heavy-duty manifold gauges and rated hoses. When diagnosing low performance, check suction line superheat numbers to confirm true capacity values before adding extra charge.
