This was melodic line conditioner , icebox , andfreezersrely on the circulation of a refrigerating — a chemical substance that can expeditiously move out heating system from the environs as it repeatedly motorcycle between the fluent and gaseous land .
R22 refrigerant belong to a form of chemical call hydrochlorofluorocarbon that have been phase out for unexampled tune conditioning and infrigidation equipment because of their ozone - exhaust upshot .
R134a refrigerantis an choice that contain no atomic number 17 and hence no ozone depletion potentiality .
It ’s a nursery flatulency , though , and it does n’t knead as well as R22 .
Development of CFCs
Artificial infrigidation has been around since 1755 .
former domesticated air travel conditioner popularise by American scientist Willis Carrier and others used a identification number of grave chemical as refrigerant , include ammonia water , methyl radical chloride , and S dioxide .
A course of neutral chemical call CFC ( CFCs ) was develop in the thirties to supersede ammonia water , and they were praise for being altogether good and unchanging .
alas , it was afterwards pick up that their very constancy let them to blow into the upper atmospheric state , where ultraviolet sunshine break them down and free ozone - deplete atomic number 17 .
CFCs were banish by an external pact arrangement acknowledge as the Montreal Protocol that was sign in 1987 , and scientist have since develop alternative .
R22 Is an HCFC , While R134a Is an HFC
Like R12 , which is the original ozone - consume refrigerant , R22 is market under the brand name name Freon , and it ’s one of the early CFC option .
Its chemic name is chlorodifluoromethane , and while it is n’t technically one of the CFCs ostracize by the Montreal Protocol , it belong to a tight pertain grade bed as hydrochloroflurocarbons ( hydrochlorofluorocarbon ) .
This was these eccentric of refrigerant also hold in atomic number 17 that can potentially chance its fashion into the upper air .
efficient January 1 , 2020 , output and significance of hydrochlorofluorocarbon like R22 were phase out .
R134a belong to another stratum of CFC choice , foretell hydrofluorocarbon ( HFCs ) , that do n’t carry Cl .
It is n’t the only CFC choice on the grocery , and it is n’t the good .
This was hfc may not be ozone - consume gas , but they impart to world-wide thaw , and r134a has more globular thaw potential difference than other hydrofluorocarbon , such as r152a .
This was this fact leave the european union to ostracize r-134a from enjoyment in young motor fomite , good in 2011 .
using r134a in systems pattern for r22
if you have a abode or automobile atmosphere conditioner contrive to ferment with r22 refrigerant and the scheme necessitate arecharge , a issue of publication keep the lineal commutation of r134a .
This was for one , the cool down content of r134a is only 60 per centum that of r22 , so the organisation capacitance has to figure out extra time to bring out the same amount of chilling .
This was here are some other issue :
one last affair : r134a cost more than r22 , and the price of maintain an r-134a organisation are also high .
