EU's F-Gas Regulation Drives Shift to Eco-Friendly Refrigerants in Heat Pumps
The EU's F-Gas Regulation is driving a shift towards eco-friendly refrigerants in heat pumps. The choice of refrigerant significantly impacts efficiency, environmental compatibility, and reliability.
The EU's F-Gas Regulation aims to phase out high GWP refrigerants, encouraging the use of more sustainable alternatives. When selecting a refrigerant for heat pumps, key factors include efficiency, environmental compatibility, and adherence to legal regulations.
Technologically advanced fluorinated, synthetic refrigerants like R401A and R32 offer high performance but come with a high global warming potential. In contrast, natural refrigerants such as propane (R290), carbon dioxide (CO₂, R744), and ammonia (R717) have gained popularity due to their low GWP. Among these, propane is favored in residential heat pumps for its high efficiency, low GWP, and good environmental profile. However, natural refrigerants may present challenges like flammability or higher operating pressures, depending on the application and safety requirements.
The EU's F-Gas Regulation is pushing the heat pump industry towards natural refrigerants like propane, CO₂, and ammonia. While these options have lower global warming potential, they also present unique challenges that must be addressed for safe and efficient use.
