• for foam sheathing that could be formed using R-123, an HCFC (it is assumed tbat 25 % more gas will be required to create the foam due to the lower blowing efficiency of R-123 and that CO2 emissions are higher because of an assumed lower R-value for the foam). In this case, the
  • HCFC Phase out Schedule. January 2010 : A ban on the manufacture of new equipment using R-22. January 2020 : End of production of HCFC’s except R-123. A ban on the manufacture of new equipment using R-123. January 2030 : End of production and importation of R-123. HCFC Consumption Phase out. 1996 establish a cap for HCFC’s …
  • only 8 HCFCs (HCFCs-21, -22, -123, -124, -141b, -142b, -225ca, and HCFC-225cb) out of the total of 274 HCFCs included in Annex C (274 is the sum of all C 1–C 3 HCFC isomers). Of the 274 HCFCs, only 15 have experimental 10 kinetic and/or infrared absorption spectrum measurements used to determine their GWPs. The majority of the HCFCs
  • (HCFC-141b must be phased out of Japan by 2004; phase out dates for other countries vary from 2010-2040.) Potential replacements, the `third generation` blowing agents, are partially hydrogenated fluorocarbons (HFCs) and some hydrochlorofluorocarbons (HCFCs) and include compounds such as HFC-134a, HFC-236ea, HFC-245fa, HFC-365mfc, and HCFC-22.
  • HCFC 142b, which is used in some refrigerant blends, will be phased out on the same schedule as R-22. HCFC-123, which is used in some centrifugal chillers, cannot be manufactured or imported for use in new equipment beginning on Jan. 1, 2020. From Jan. 1, 2020 until Jan. 1, 2030, new HCFC-123 can be only be used in equipment manufactured prior ...
  • Jun 21, 2018 · Nowadays it is R-134. Very recently it was R-22 which is no longer manufactured due to irrational concerns about it's global warming potential. Somewhat silly because generally people don't buy it and vent it into the atmosphere for no reason.
But as global regulatory mandates require the phase-out of R-11, many chillers use Freon™ 123 (R-123) refrigerant as an alternative because of its low ozone depleting properties. The thermodynamic and physical properties of Freon™ 123 make it efficient and safe for use as a replacement in new systems and as a retrofit in installed equipment.

Complete information for HCFC1 gene (Protein Coding), Host Cell Factor C1, including: function, proteins, disorders, pathways, orthologs, and expression. GeneCards - The Human Gene Compendium.The "2010 HCFC Allocation Rule" allocated allowances for each year between 2010 and 2014. To meet the stepdown, the number of allowances for HCFC-22 and HCFC-142b were less than for the 2003-2009 control periods. EPA also issued allowances for HCFC-123, HCFC-124, HCFC-225ca, and HCFC-225cb.
Jul 31, 2019 · HCFC R-123 allocations will be increased, then drop. If you own, are planning to own an R-123 chiller, you will be happy to know the EPA is suggesting allowances be increased by more than 4M lbs after 2020. Under the status quo that number would have been closer to 2M lbs. However, keep in mind that this is still a reduction of 2M lbs overall.
Du Pont has started construction on pilot plants to produce HFC-134a, HCFC-123, and HCFC-141b and has announced plans to build commercial-scale plants for HFC-134a and HCFC-141b/142b. The company says it will spend $1 billion over the next 10 years on plants to make CFC replacements. Out of 40 transitional ODPs listed in Annex C, in Russia HCFC-21, HCFC-22, HCFC-141b, and HCFC-142b are most commonly used. These substances are widely used in the domestic, commercial and industrial HVAC equipment, as well as for manufacturing insulation boards, plates, panels, and coatings for water, gas, and oil pipelines.
Future effort will be put into the support and implementation of the proactive industry commitments as granted by several industry user groups as well as adoption of the European HCFC phase-out common. Jun 11, 2020 · Although HCFCs are to be phased out by 2020, our results are expected to help developing the database of vapor–liquid equilibria for halogenated compounds and thermodynamic model like UNIFAC. 2 Measurement 2.1 Materials HFC-32 and HCFC-142b are supplied by Ulsan Chemical with a minimum purity of 99.9 mass%, and HCFC-123 was supplied by DuPont with a purity of 99.95 mass%.
