R404a daim ntawv thov
404A (R-404A) refrigerant gas muaj feem xyuam rau ntau yam kev siv. Xws li lub hauv paus cua txias, chav ua lag luam tub yees, chav nyob sab nraum zoov AC, tub yees chav tsev, vending machines, showcases, freezers units, thiab lwm yam.
Feem ntau, r404a refrigerant haum rau tag nrho R502 raws li daim ntawv thov raws li nws muaj zoo sib xws nrog R502 refrigerant gas lub zog.
R404a refrigerant gas kuj tseem siv rau ntau hom compressor thiab lawv cov condensing units.

Yog tias koj nug dab tsi refrigerant yuav hloov R404a, qhov ntawd yog tej zaum R407A refrigerant.
Tab sis R404 refrigerant yog ib qho qauv tsim uas yuav haum rau hloov koj R-502 thiab R-22 tag nrho cov kev lag luam thiab cov khoom siv tub yees.
Cov neeg kuj nug seb lawv puas tuaj yeem sib xyaw R404a nrog 134a lossis siv R134 hauv R404A system, tab sis koj tsis xav tau qhov no.
Vim tias R404A twb muaj R134 refrigerant gas thiab lub tshuab nqus tsev sib xyaw tsis tsim nyog.
