R-1234yf, lossis HFO-1234yf sai sai no yog ib qho ntawm cov tub yees ua kev lom zem tshaj plaws hauv ntiaj teb. Ua rau nws pib ua ntej xyoo 2000's nws tau nce siab sai zog thiab yuav dhau los ua cov tub yees nyob hauv kev lag luam tsheb. Niaj hnub no, raws li kuv sau qhov no hauv Lub Kaum Hlis 2017 muaj kwv yees li peb caug-tsib lab tsheb ntawm txoj kev uas siv 1234yf. Tus lej no tsuas yog nce raws li R-134a tsis tso cai rau cov qauv tshiab hauv European Union thiab yuav txwv tsis pub ua qauv tshiab nyob hauv Tebchaws Meskas thaum 2020. (2021 tus qauv xyoo.)
