Which refrigerant types are considered less harmful to the environment than traditional F-Gases?

The selection of hydrocarbons, ammonia, and carbon dioxide as refrigerant types that are considered less harmful to the environment than traditional F-Gases is accurate due to several key factors.

Hydrocarbons, which include substances such as propane and isobutane, have a very low global warming potential (GWP) compared to traditional F-Gases. They are natural compounds and are relatively safe when handled properly. Ammonia, while requiring caution due to its toxicity, is also a low-GWP option and is widely used in industrial refrigeration systems because of its efficiency and minimal environmental impact. Carbon dioxide has an extremely low GWP and is abundant in nature, making it a viable option in various applications, including commercial refrigeration.

In contrast, the other types of refrigerants listed, such as hydrochlorofluorocarbons, chlorofluorocarbons, and perfluorocarbons, have significant environmental drawbacks. Hydrochlorofluorocarbons and chlorofluorocarbons are implicated in ozone layer depletion and have high GWP values. Perfluorocarbons are potent greenhouse gases with very high GWP, contributing significantly to climate change. Therefore, the choice of hydrocarbons, ammonia, and CO
