F-Gases are fluorinated hydrocarbons. Many, such as halocarbon 14, or CF4 are used extensively in semiconductor processing. Others are used for industrial, commercial, and domestic refrigeration applications.
R404A, which is a blend of three different F-Gas molecules, is used in commercial refrigeration to enable the chilled and frozen food supply chains. Difluoromethane, or R32 which has the formula CH2F2, is gaining favour as a refrigerant gas in domestic and commercial air conditioning units.
F-Gases are also commonly used for mobile air conditioning in buildings and cars. For example, R134a and R1234yf are the two main automotive air conditioning gases that have been used in recent years.
Heat pumps can support the energy transition from fossil fuel heating to the use of renewable electricity. They use F-Gases in their circuits to capture low-grade heat from ambient air and upgrade that to usable warmth in our homes, hotels, and offices.
