What are HFCs?

What are HFCs?

• A. Naturally occurring cooling agents.
• B. Gases that deplete ozone.
• C. Man-made gases used as refrigerants.
• D. Inert gases used for shielding.

Answer: (C)

Hydrofluorocarbons are synthetic refrigerants developed to replace ozone-depleting substances. They are man-made gases used in cooling systems such as air conditioners and refrigerators. They don’t contain chlorine, which is why they don’t harm the ozone layer, making them a safer choice for that specific issue. However, many HFCs are powerful greenhouse gases, so leaks contribute to climate change. They aren’t naturally occurring cooling agents, aren’t gases that deplete ozone, and aren’t inert shielding gases. An example you might see is HFC-134a, a common refrigerant.
