The refrigeration sector end-use is CFC-114 industrial process refrigeration, with an acceptable substitute of HFC-236fa. CFCs were first developed in the 1920s to replace sulphur dioxide as a coolant gas. Federal Register Citation: 64 FR 22981. The solvent end uses include metal cleaning, electronic cleaning and precision cleaning with CFC-113. Source: IPCC, 2007: Climate Change 2007: The Physical Science Basis. The determinations all include substitutes previously listed as substitutes for other ODS or as substitutes for HCFC-22 alone. 9000 /3[43]. Instead of the more conventional ammonia or haloalkane gases, EcoCute uses supercritical carbon dioxide as a refrigerant.The technology offers a means of energy conservation and ( ) . The ozone depleting substitutes are for use in the following sectors: refrigeration and air conditioning; aerosols; and adhesives, coatings, and inks. In the 1930s they began to replace ammonia for cooling uses.

The determinations concern new substitutes. Additional information: DSPA generators produce combustion byproducts (micron-sized dry particles and a gaseous mixture), that mix together into a uniform fire-extinguishing aerosol before being released into the protected area. Another important group of human-produced halocarbons is the halons, which contain carbon, bromine, fluorine, and (in some cases) chlorine and have been mainly used as fire extinguishers.

FOR12A and FOR12B for an acceptable substitute of HCFC-22 and CFC-12, NU-22 for an acceptable substitute of HCFC-22, and SP34E for an acceptable substitute of CFC-12 for the refrigeration and air-conditioning end-uses; industrial process refrigeration and air-conditioning, industrial process refrigeration, cold storage warehouses, refrigerated transport, retail food refrigeration, ice machines, vending machines, water coolers, centrifugal chillers, reciprocating chillers, household refrigerators and freezers, residential air conditioning and heat pumps, residential dehumidifiers, motor vehicle air conditioning and buses only. This notice lists acceptable substitutes for the end-uses of refrigerants, fire suppression and explosion protection, foam blowing, and solvent cleaning. They were banned in 1996 in all countries. This use hit its peak in the late 1970s, when CFC was identified as an ODS and aerosols became the main target of public action. Smaller quantities of carbon tetrachloride were used in fire extinguishers, as a dry cleaning agent, and as an ingredient in pesticides, pharmaceuticals, paints and solvents. Benzotrifluoride is an acceptable substitute with an exposure limit (AEL) of 100 ppm for all solvent cleaning, aerosols solvents, adhesives, coatings, and inks end-uses. EPA is rescinding use conditions that limit human exposure to halocarbon and inert gas agents used in the fire suppression and explosion protection industry. This final action modifies the use conditions required for use of three flammable refrigerantsisobutane (R-600a), propane (R-290), and R-441Ain new household refrigerators, freezers, and combination refrigerators and freezers under the Significant New Alternatives Policy (SNAP) program. . 0,04%[5].
