HFC 134a thiab R134a

HFC 134a thiab R134a

 

134a refrigerant yog ib qho kev tshawb fawb zoo kawg nkaus, suav nrog hydrofluorocarbon (HFC) compound ua los ntawm carbon, hydrogen, thiab fluorine atoms, nrog rau cov tshuaj formula CH2FCF3. Txawm hais tias nws muaj qhov muaj peev xwm ua rau lub ntiaj teb ua kom sov siab (GWP), nws raug cais raws li lub tsev cog khoom roj uas muaj kev cuam tshuam tsawg dua ntawm cov txheej txheem ozone piv rau chlorofluorocarbons (CFCs) thiab hydrochlorofluorocarbons (HCFCs).

 

Ib qho txiaj ntsig tseem ceeb ntawm 134a refrigerant yog nws kev sib raug zoo nrog cov tshuab cua txias uas twb muaj lawm. Nws tuaj yeem siv los ua ib qho poob - hloov pauv rau cov tub yees qub xws li R12 (CFC) thiab R22 (HCFC), ua rau nws xaiv yooj yim rau kev rov kho cov cuab yeej uas twb muaj lawm yam tsis muaj kev hloov pauv loj.

R 134a yog qhov kev xaiv muaj kev nyab xeeb thiab txhim khu kev qha rau ntau yam kev siv. Tsis zoo li ntau lwm cov tub yees, nws khav theeb qhov tsis yog -flammable xwm uas tshem tawm txhua qhov kev pheej hmoo ntawm hluav taws kub. Qhov no feature tiv thaiv tsis tau tsuas yog cov cuab yeej tab sis kuj cov neeg siv nws.

R 134A refrigerant muaj tshuaj lom neeg ruaj khov, ua kom muaj kev ua haujlwm txias txias rau lub sijhawm ntev. Nws yog incredibly resilient thiab tsis degrade, tswj nws cov hauj lwm zoo nyob rau hauv ib tug dav lifespan.

Thaum muab piv R134a refrigerant rau lwm txoj hauv kev, ntau yam tuaj rau hauv kev ua si:

R134a vs R22:R22 yog cov tub yees qub uas tau ua dhau los vim nws cov ozone -depleting zog. R134a feem ntau hloov R22 hauv cov tshuab uas twb muaj lawm, muab kev sib raug zoo thiab kev ua haujlwm zoo ib puag ncig.

R134a vs Hydrocarbons:Hydrocarbon refrigerants, xws li R290 (propane) thiab R600a (isobutane), tau txais kev saib xyuas rau lawv cov GWP qis thiab ozone- tus phooj ywg xwm. Txawm li cas los xij, lawv yog cov nplaim taws thiab xav tau kev ntsuas kev nyab xeeb ntxiv thaum tuav thiab teeb tsa, tsis zoo li tsis yog -flammable R134a.

R134a vs HFOs:Hydrofluoroolefin (HFO) refrigerants, xws li R1234yf thiab R1234ze, yog suav tias yog tiam tom ntej ntawm ib puag ncig tus phooj ywg tub yees. Lawv muaj GWPs tsawg heev thiab xoom ozone depletion muaj peev xwm. Txawm li cas los xij, lawv qhov kev saws me nyuam tseem tab tom ua tiav, thiab R134a tseem yog qhov kev xaiv dav thiab muaj pov thawj.

Tsim los ntawm 1988 los ntawm Tuam Tshoj tus kws tsim tshuaj pioneer Juhua Group Corporation, Xiamen Juda tau tsom mus rau cov tshuaj fluorinated export txij thaum xyoo 2004. Peb 7 cov khoom lag luam fluorinated tseem ceeb suav nrog: Cov Khoom Siv Hluav Taws Xob, Cov Tshuaj Kho Mob Aerosol Propellant, Txias Agent, Fire Extinguishing Agent, Welding Gas.

"Kev Pabcuam Cov Neeg Siv Khoom, Txhim Kho Kev Lag Luam" yog peb lub luag haujlwm rau lub sijhawm ntev thiab kev sib koom ua lag luam muaj txiaj ntsig zoo nrog cov neeg siv khoom.
