A2L Refrigerant Safety for Gas-fired HVAC Systems (October 30, 2024)


Description
A2L refrigerants are characterized by mild flammability, low toxicity, and low global warming potential (GWP). They include hydrofluoroolefins (HFOs) and HFO blends. A2L refrigerants offer similar operating characteristics to legacy refrigerants, a safer profile than ammonia and hydrocarbon refrigerants, and are more energy efficient than R-410A and transcritical CO₂ systems.
