Why R-32 is More Energy Efficient than Other Refrigerants
1. Lower Global Warming Potential (GWP) and Improved Heat Transfer
- R-32 has a GWP of 675, which is 70% lower than R-410A (GWP 2,088), reducing environmental impact.
- Due to superior thermodynamic properties, R-32 improves heat transfer efficiency, requiring less energy for the same cooling output.

2. Reduced Refrigerant Charge Requirements
- R-32 systems use 30% less refrigerant than R-410A units, reducing the total environmental impact and improving energy efficiency.
- Less refrigerant means lower operational costs and reduced energy consumption per cooling cycle.

3. Compatibility with High SEER2 Ratings
- R-32 is commonly used in air conditioners with higher SEER2 (Seasonal Energy Efficiency Ratio 2) ratings, which maximize cooling efficiency and reduce energy bills.
- Upgrading from a 14.3 SEER2 to a 16.2 SEER2 R-32 AC can provide up to 15% energy savings annually.

2. Faster Cooling and Less Runtime
- Since R-32 has better heat exchange properties, it allows the AC to cool a room 30% faster than R-410A units.
- Faster cooling means less compressor runtime, reducing overall electricity usage.
3. Lower Peak Load Demand
- HVAC systems account for nearly 50% of household energy consumption during peak summer months.
- R-32’s high efficiency helps reduce demand during peak hours, lowering energy costs.
