As global industries push toward low-GWP (Global Warming Potential) refrigerants, 1,1-Difluoroethane (R152a) is emerging as a viable, environmentally friendlier alternative to the widely used R134a. Known for its significantly lower GWP and energy-efficient performance, R152a is gaining traction in HVAC and refrigeration sectors worldwide.
R152a refrigerant gas, chemically named 1,1-Difluoroethane (C2H4F2), is a hydrofluorocarbon (HFC) refrigerant with excellent thermodynamic properties. With a GWP of only 124 (compared to R134a’s 1430), R152a offers a significant environmental benefit by reducing greenhouse gas emissions while maintaining high cooling efficiency.
Its thermophysical characteristics make it suitable for use in refrigeration systems, air conditioners, and even as a propellant in aerosol applications. It is non-corrosive, highly efficient, and provides better heat transfer performance in some systems than R134a.
| Property | R152a | R134a |
|---|---|---|
| Chemical Formula | C2H4F2 | CH2FCF3 |
| Global Warming Potential (GWP) | 124 | 1430 |
| Ozone Depletion Potential (ODP) | 0 | 0 |
| Boiling Point (°C) | -24.7 | -26.1 |
| Latent Heat of Vaporization (kJ/kg) | 362 | 216 |
| Critical Temperature (°C) | 113.5 | 101.1 |
| Flammability | Flammable (A2) | Non-flammable (A1) |
Despite being slightly flammable, R152a’s environmental benefits and cooling performance make it a top choice for eco-conscious applications, especially when used in systems designed with proper safety measures.
Low GWP: Only 124, which drastically reduces climate impact.
High Cooling Efficiency: Excellent thermodynamic performance and high latent heat value.
Lower System Charge: Requires less refrigerant volume due to high efficiency.
Non-corrosive & chemically stable in appropriate environments.
Compatible with many existing components when system design is adjusted.
R152a is primarily used in:
Aerosol propellants
Automotive air conditioning (as a blended component)
Refrigeration equipment with safety-engineered systems
Industrial and commercial chillers
Portable and plug-in cooling devices
In some systems, R152a can be used as a drop-in or blended substitute for R134a, providing both environmental and energy efficiency benefits when applied with proper engineering controls.
