HFCs are synthetic greenhouse gases commonly used as replacements for CFCs and HCFCs in various applications like air conditioning and refrigeration. They do not deplete the ozone layer but have a high global warming potential.
The process where certain gases in Earth's atmosphere trap heat from the sun, causing an increase in temperature on our planet.
Global Warming Potential (GWP): A measure of how much heat a greenhouse gas can trap in the atmosphere over time compared to carbon dioxide (CO2). HFCs have a high GWP.
Refrigerants: Substances used in cooling systems, such as air conditioners and refrigerators, to transfer heat from one place to another. HFCs are commonly used as refrigerants.
