R404A yog ib hom hydrofluorocarbon (HFC) refrigerant feem ntau siv hauv kev lag luam tub yees, xws li cov khw muag khoom noj khoom haus tub yees thiab lub tub yees. Nws yog kev sib xyaw ntawm peb qhov sib txawv HFCs: R125, R143a, thiab R134a. R404A tau siv los hloov cov chlorofluorocarbons (CFCs) thiab hydrochlorofluorocarbons (HCFCs), uas tau raug tshem tawm vim lawv cov teeb meem cuam tshuam rau txheej txheej ozone. R404A muaj lub peev xwm ua kom sov thoob ntiaj teb siab (GWP) thiab tab tom raug txiav tawm hauv qee lub tebchaws vim nws txoj kev koom tes rau kev hloov pauv huab cua. Lwm txoj hauv kev nrog GWPs qis dua tau tsim thiab siv, xws li R448A thiab R449A.
1. Cov tub yees - R404 feem ntau yog siv los ua cov roj tub yees rau kev lag luam thiab kev lag luam tub yees, nrog rau lub freezers, coolers, thiab cua txias systems.
2. Cov cua txias - R404 kuj tseem siv los ua cov roj cua txias hauv cov tshuab cua txias hauv tsheb, tsheb npav, thiab lwm yam tsheb.
3. Kev txuag zaub mov - R404 feem ntau yog siv los khaws cov khoom noj khov thiab dej haus.
4. Kev Kho Mob - R404 yog siv rau hauv kev siv kho mob xws li cov tshuaj tiv thaiv kub qis thiab cov khoom siv hauv chav kuaj kom txias.
5. Muaj cua txias - R404 yog siv nyob rau hauv ntau yam kev lag luam txias daim ntaub ntawv xws li tshuaj ua, roj thiab roj refining, thiab dej khov rinks.
