Equipment manufactured before 2010 may use hydrochlorofluorocarbon (HCFC) refrigerant. Some newer equipment uses hydrofluorocarbon (HFC) refrigerants, which contain no chlorine. CFC refrigerants. These are substances containing CARBON, FLORINE and CHLORINE chemicals.

Chlorofluorocarbons(CFCs) are stable, synthetic, halogenated alkanes, developed in the early 1930s as safe alternatives to Chlorofluorocarbons are refrigerants that contain chlorine. R245c and R245fa are used almost exclusively in the United States and in a rather experimental Chlorofluorocarbons (CFCs) have been widely used throughout the world.

While in the 90s, the fact that CFC (Chlorofluorocarbon) is highly involved in the depletion of the ozone layer was quite in talks. The Chlorofluorocarbon, which is most commonly known as Freon , was used as a refrigerant back those days.

T.ex. så används ordet freoner istället för CFC-gaser i US98. av A Rosendal · 2011 — sorting systems that could be used on Stormossen´s area. In the first kg CO2-ekvivalenter, till ozonnedbrytning 6,76 mg CFC-11-ekvivalenter, till bildning Remark: The multioutput-process 'biogas, burned in micro gas turbine delivers the.

The word "aerosol" also refers to the dispenser or package used to change the ingredient inside the container into an aerosol. The aerosol spray can dates back to 1926, when Norwegian inventor Eric Rotheim discovered that a product could be sprayed from an aluminum can that had been injected with gas or liquid to build pressure.
