Which refrigerants are known for being ozone-friendly?

Natural refrigerants are considered ozone-friendly because they typically have a low or zero ozone depletion potential (ODP). These refrigerants include substances such as ammonia, carbon dioxide, and hydrocarbons like propane and isobutane. Unlike synthetic refrigerants, natural options do not contain chlorine, which is responsible for ozone depletion when released into the atmosphere.

The shift towards using natural refrigerants aligns with environmental policies aimed at reducing the impact of refrigerants on the ozone layer and minimizing overall greenhouse gas emissions. Their minimal environmental impact makes them a sustainable choice in modern refrigeration applications, helping businesses meet stricter regulations regarding ozone depletion and contributing to global efforts for environmental protection.

In contrast, the other refrigerants mentioned, such as CFCs, HFCs, and HCFCs, either contribute to ozone depletion or have high global warming potential, making them less desirable in terms of environmental impact.
