2. 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 ...

3. List of refrigerants - Wikipedia

   en.wikipedia.org/wiki/List_of_refrigerants

   According to ASHRAE standard 34, the R-number of a chemical refrigerant is assigned systematically according to its molecular structure and has between two and four digits. If there are carbon -carbon multiple bonds , there are four digits in all: the number of these bonds is the first digit and the number of carbon atoms minus one (C-1) is next.

4. Vapor-compression refrigeration - Wikipedia

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

   A representative pressure–volume diagram for a refrigeration cycle. 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.

5. Hydrofluorocarbon - Wikipedia

   en.wikipedia.org/wiki/Hydrofluorocarbon

   They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFC refrigerants. In order to aid the recovery of the stratospheric ozone layer, HFCs were adopted to replace the more potent chlorofluorocarbons (CFCs), which were phased out from use by the Montreal Protocol ...

   Here's how to distinguish "sundowning"—agitation or confusion later in the day in dementia patients—from typical aging, from doctors who treat older adults.

8. 1,1,1-Trifluoroethane - Wikipedia

   en.wikipedia.org/wiki/1,1,1-Trifluoroethane

   Unlike CFCs used as refrigerants, trifluoroethane has no chlorine atoms and therefore is not ozone-depleting. Its high chemical stability and infra-red absorbency make it a potent greenhouse gas with a lifetime of about 50 years and a global warming potential of 4300, which are at the high end compared to many other commonly used HFC refrigerants.
