Brief Summary of A2L Refrigerants
The incorporation of A2L refrigerants is an easy way to reduce Global Warming Potential as they are classified as mildly flammable and are more environmentally friendly than high-GWP hydrofluorocarbons (HFCs). Global Warming Potential has been developed to allow comparisons of the global warming impacts of different gases. Specifically, it is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2).
A2L refrigerants have a lower GWP, making them a more energy-efficient choice. Their name is based on their ASHRAE safety classification. “A” stands for “non-toxic”. A2L refrigerants are non-toxic. When used properly, they are not harmful to human health. “2” indicates their flammability: A2L refrigerants are moderately flammable. They have a lower flammability level compared to A3 (highly flammable) refrigerants. However, they are still considered flammable and need to be dealt with carefully. “L” means they have lower toxicity levels compared to some other refrigerants.
TRANSITIONING TO A2L Refrigerants
Starting next year, HFC production will be cut by 40% and the transition to A2L in manufacturing will be nearing completion. The Environmental Protection Agency (EPA) has begun to phase out R410-a refrigerant in new HVAC systems, aiming to replace it with more environmentally-friendly, energy-efficient alternatives, specifically A2L refrigerants.
