Molecular Weight: 52.02 g/mol

Boiling Point: (at 1 atm)-51.7 °C (-61.1 °F)

Freezing Point: -136.8 °C (-214.2 °F)

Critical Temperature: 78.1 °C (172.6 °F)

Critical Pressure: 5.78 MPa (838 psia)

Critical Density: 424 kg/m³

Liquid Density (at 25°C): ~950 kg/m³

Vapor Density (air=1): 1.8 (heavier than air)

Specific Heat (Liquid, 25°C): ~1.57 kJ/(kg·K)

Specific Heat (Vapor, 25°C): ~0.83 kJ/(kg·K)

Thermal Conductivity: Higher than R410A, improving heat exchanger efficiency.

Viscosity: Lower than R410A, reducing pressure drop in systems.

Flammability: Class A2L. Mildly flammable. It has a low burning velocity and a high Lower Flammability Limit (LFL), making it harder to ignite and sustain a flame compared to hydrocarbons.

Lower Flammability Limit (LFL): 14.4% by volume in air.

Upper Flammability Limit (UFL): 29.3% by volume in air.

Auto-Ignition Temperature: 648 °C (1198 °F)

ODP (Ozone Depletion Potential): 0 – Does not deplete the ozone layer.

GWP (Global Warming Potential): 675 (IPCC AR5, 100-yr). This is about 1/3 of R410A's GWP (~2088).

Atmospheric Lifetime: ~5.2 years (much shorter than R410A).

Toxicity: Class A (Low Toxicity). However, at high concentrations, it can act as a simple asphyxiant and, like all refrigerants, decompose into toxic fumes (HF, carbonyl fluoride) if exposed to an open flame or extreme heat.

High Volumetric Cooling Capacity: Approximately 1.5 times greater than R410A. This means smaller displacement compressors can be used for the same cooling effect.

C.O.P. (Coefficient of Performance): Similar to or slightly higher than R410A, offering good energy efficiency.

Glide: Near Azeotropic (~0.5 K). It behaves almost like a single-component refrigerant, simplifying system design and service.

Discharge Temperature: Higher than R410A, which requires specific compressor design considerations for reliability.
