  2. Dichlorodifluoromethane - Wikipedia

    en.wikipedia.org/wiki/Dichlorodifluoromethane

    Dichlorodifluoromethane ( R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant. In compliance with the Montreal Protocol, its manufacture was banned in developed countries (non-article 5 countries) in 1996, and in developing countries ...

  3. HC-12a - Wikipedia

    en.wikipedia.org/wiki/HC-12a

    HC-12a is a mixture of hydrocarbons, specifically propane (R-290) and isobutane (R-600a), and is therefore considered nearly non-ozone-depleting compared to dichlorodifluoromethane (R-12, Freon-12) or 1,1,1,2-tetrafluoroethane (R-134a). The mixture can be used in refrigeration systems designed for R-12.

    Refrigerant concentration limit / immediately dangerous to life or health in parts per million (volume per volume) and grams per cubic meter Molecular mass in atomic mass units Normal boiling points for pure substances, bubble and dew points for zeotropic blends, or normal boiling point and azeotropic temperature for the azeotropic blends, at ...

  5. Refrigerant - Wikipedia

    en.wikipedia.org/wiki/Refrigerant

    Refrigerant. A refrigerant is a working fluid used in the refrigeration cycle of air conditioning systems and heat pumps where in most cases they undergo a repeated phase transition from a liquid to a gas and back again. Refrigerants are heavily regulated because of their toxicity and flammability and the contribution of CFC and HCFC ...

  6. 1,1,1,2-Tetrafluoroethane - Wikipedia

    en.wikipedia.org/wiki/1,1,1,2-Tetrafluoroethane

    1,1,1,2-Tetrafluoroethane (also known as norflurane (), R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion potential and a lower 100-year global warming ...

  7. Difluoromethane - Wikipedia

    en.wikipedia.org/wiki/Difluoromethane

    Difluoromethane, also called difluoromethylene, HFC-32 Methylene Fluoride or R-32, is an organic compound of the dihalogenoalkane variety. It has the formula of CH 2 F 2. It is a colorless gas in the ambient atmosphere and is slightly soluble in water, with a high thermal stability. [ 2][failed verification] Due to the low melting and boiling ...

  8. 2,3,3,3-Tetrafluoropropene - Wikipedia

    en.wikipedia.org/wiki/2,3,3,3-Tetrafluoropropene

    2,3,3,3-Tetrafluoropropene, HFO-1234yf, is a hydrofluoroolefin (HFO) with molecular formula CH 2 =CFCF 3. Its primary application is as a refrigerant with low global warming potential (GWP). [ 1][ 2] As a refrigerant, it is designated R-1234yf[ 1] and marketed under the names Opteon YF by Chemours and as Solstice YF by Honeywell. [ 3]

  9. Vapor-compression refrigeration - Wikipedia

    en.wikipedia.org/wiki/Vapor-compression...

    Vapour-compression refrigeration or vapor-compression refrigeration system ( VCRS ), [ 1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles. It is also used in domestic and commercial refrigerators, large-scale warehouses ...
