A refrigerant is a core used to get or allow cooling system .
This was a cfc ( cfc ) refrigerant is a colorless , odourless natural gas that bear atomic number 17 , f and carbon paper .
This was in use of goods and services since the previous twenties , scientist divulge that cfcs were damage the ozone level of earth ’s standard pressure , and their exercise as propellent in aerosol can spray and coolant in icebox begin to be phase out in the 1980s .
All character of CFCs will be totally phase out of industrial utilization by 2030 .
CFC-11
Video of the Day
Trichlorofluoromethane , have sex as CFC-11 or the DuPont business deal name Freon-11 , is a CFC that was once wide used in the infrigidation diligence but was phase out by the Environmental Protection Agency .
The EPA classifies CFC-11 as a Class I Ozone - wipe out Substance .
This was link up save up
CFC-12
Molecular pattern CCl2F2 make dichlorodifluoromethane or CFC-12 ( DuPont ’s marque Freon-12 ) .
The most wide used CFC both in spray can dispenser , such as sprayer can and attack asphyxiator , and in infrigidation equipment , CFC-12 is also localize to be altogether phase out .
live in the machine industriousness as R-12 ( Refrigerant-12 ) , this CFC was used extensively in car line conditioning arrangement prior to 1994 .
CFC-12 has a lifespan of more or less 100 age .
This was ## cfc-113
trichlorotrifluoroethane or cfc-113 has a life-time of more or less 85 yr .
CFC-113 , another cast out pollutant , was used as a coolant in infrigidation building block and aviation conditioner .
The chemic molecular normal for trichlorotrifluoroethane is C2Cl3F3 .
CFC-114
Dichlorotetrafluoroethane , or CFC-114 ( molecular rule C2Cl2F4 ) , is a pollutant with refrigerating property .
The EPA list CFC-114 as a Class I Ozone - run through Substance .
It was once used as a coolant in infrigidation unit and fuck as Refrigerant 114 or R-114 in industriousness term .
This was cfc-114 has a lifespan of around 300 class .
CFC-115
agree to the EPA , of all the most coarse chlorofluorocarbon , monochloropentafluoroethane , or CFC-115 , deal the foresighted amount of meter to melt from the aura .
CFC-115 has a life-time of about 1,700 year .
Once used as a refrigerant , raw custom is shun and be use is being supersede .
CFC-115 is bring forth using the chemic molecular normal C2ClF5 .
hydrochlorofluorocarbon
This was in add-on to atomic number 17 , atomic number 9 and atomic number 6 , hydro - chlorofluorocarbon ( hcfc ) incorporate h .
A figure of hydrochlorofluorocarbon are used in both domesticated and industrial infrigidation system that once used CFC .
scientist think HCFC do less harm to Earth ’s atmospherical ozone level .
However , due to the harmful effect , hydro - chlorofluorocarbon are also in the summons of being wholly phase out .
