Tebchaws Asmeskas raug txwv tsis pub ua raws li cov cai nyob hauv tsev. Txij li xyoo 2017, qhov kev ntshuam ntawm Tuam Tshoj' s Refrigerant Gas R134A tau nqis los ntawm ntau dua 20,000 tons hauv 2016 rau ntau tshaj 4,000 tons hauv 2017, thiab nws yuav yog kaum tawm tons hauv 2019. Raws li lub Peb Hlis 2020, Tebchaws Asmeskas tau import tag nrho R134A Txog 5 tons.
Qhov laj thawj tseem ceeb yog: Xyoo 2016, US Environmental Protection Agency (EPA) tau tshaj tawm ob txoj cai tias, thaum txwv tsis pub siv qee lub tub yees, muaj kev cai nruj txog kev xoom xaim nqi, yog li txo HFC emissions. Txij Lub Ib Hlis 1, 2021, ib qho teeb ntawm GWP cov tub yees ntau tau txwv tsis pub siv hauv qee cov khoom lag luam tshiab, suav nrog R404A, R134A, R407C thiab R410A.
R134A yog ib qho ntawm cov tub yees siv dav siv. Txij li Lub Ib Hlis 1, 2024, nws yuav raug txwv tsis pub siv nyob rau hauv cov khoom tsim ua centrifugal thiab piston chillers tshiab. Ntawm chav kawm, nws kuj suav nrog R407C thiab R410A, ntxiv rau ntau yam kev hloov pauv ncaj qha ntim cov khoom sib xyaw. Nyob rau tib lub sijhawm, txij Lub Ib Hlis 1, 2021, R134a tseem yuav raug txwv tsis pub siv hauv cov tub yees txias thiab khoom siv txias.
Nws yog vim txoj cai no tau hais tias Tebchaws Asmeskas tau muaj kev poob qis rau cov neeg Suav R134A yuav khoom tom qab xyoo 2016. Txawm hais tias qhov kev thov R134A hauv cov khoom lag luam uas tsim muaj thiab kev ua lag luam tam sim no tseem muaj, Tebchaws Asmeskas suav rau qhov sib piv ntawm Suav.' s R134A kev yuav khoom hauv xyoo 2016 Yog tias nws nce mus txog ntau dua 20%, nws yuav tsis muaj txiaj ntsig rau kev sib ntsib hauv tsev nyob hauv Tebchaws Meskas, thiab R134A lwm txoj kev lag luam tau nce siab hauv Asmeskas. Piv txwv li, R1234yf kuj tseem siv tau rau cov khoom lag luam tshiab hauv nruab nrab lub tsheb thauj khoom thiab tsheb thauj khoom.
Nws tuaj yeem pom tias qhov kev thov rau R134A hauv Asmeskas kev lag luam yuav txhim kho yav tom ntej, thaum Tuam Tshoj' s R134A qhov peev xwm tsim khoom tau nrawm nrawm dua, thiab kev sib tw ua lag luam yog ntxiv zuj zus. Txawm hais tias qhov kev thov rau Tuam Tshoj' s R134A hauv kev lag luam tsim tawm tau zoo, qhov kev thov hauv cov lag luam tawm tshiab kuj tseem nyuaj rau kev zom cov peev txheej tshiab ntawm Tuam Tshoj' s R134A. Piv txwv, xyoo 2016-2019, Brazil tau yuav tag nrho 28,000 tons ntawm R134A hauv ib hlis, ntawm qhov ntawd, qhov ntau tshaj ntawm qhov kev yuav khoom xyoo 2019 tsawg dua 10,000 tons, thaum Asmeskas tau muag ntau dua 20,000 tons ntawm Suav R134A hauv xyoo 2016, thiab txij li xyoo 2016, Lub Tebchaws R134A cov khoom lag luam sib txawv Juhua thiab Sanmei tau nthuav dav lawv cov khoom. Ntxiv rau cov tuam txhab tsim khoom tshiab R134A hauv xyoo tsis ntev los no: Huaan, Dongyang Tshav Ntuj, Feiyuan, Meilan, thiab lwm yam, yog li ntawd, ntau npaum li cas R134A tus nqi tswj thiab fluorine tshuaj lom neeg kev lag luam sib txuas tau dhau los ua qhov tsom xam ntawm ntau lub lag luam yuav yog qhov xwm txheej ib txwm muaj vim muaj txiaj ntsig ntawm kev hloov pauv tus nqi, uas ua rau kev ncua ntawm kev tsim khoom lossis qhov tsis muaj peev xwm ntawm lub peev xwm tshiab mus txuas ntxiv tsav, thiab pib ntawm lub peev txheej loj ntawm qib qis. Qee qhov kev tsim khoom lag luam nrog cov saw ntev ntev hauv kev lag luam yuav muaj qee qhov zoo, tshwj xeeb tshaj yog cov chaw tsim khoom lag luam nrog cov khoom lag luam tus kheej siab, tus nqi ntau ntawm cov khoom lag luam tub yees, thiab cov kev txiav txim siab ceev ceev, yuav muaj ntau qhov zoo hauv kev ua lag luam yav tom ntej.
