What is the benefit of using a refrigerant with a low global warming potential (GWP)?

Using a refrigerant with a low global warming potential (GWP) is primarily beneficial for minimizing environmental impact. Refrigerants are significant contributors to climate change when they escape into the atmosphere, as many have high GWPs, meaning they can trap heat much more effectively than carbon dioxide. By opting for refrigerants with lower GWPs, HVAC systems reduce their contribution to greenhouse gas emissions, aligning with global efforts to combat climate change and protect the environment.

In this context, enhancing system efficiency, increasing cooling capacity, and lowering operating costs might be desirable attributes but are not directly related to the GWP value of a refrigerant. The core advantage lies in the reduced ecological footprint, making option related to environmental impact the most relevant and beneficial.
