Refrigerant R404a yog dab tsi?

Refrigerant R404A yog ib qho kev sib xyaw ntawm peb cov hydrofluorocarbon (HFC) cov tub yees siv feem ntau hauv kev lag luam tub yees. Nws yog tsim los ntawm:

44% R-125 (Pentafluoroethane)
52% R-143a (1,1,1-Trifluoroethane)
4% R-134a (1,1,1,2-Tetrafluoroethane)

Daim ntawv thov

R404A yog siv nyob rau hauv ntau yam uas tsis tshua muaj thiab nruab nrab kub daim ntawv thov tub yees, retrofitted refrigerant rau R502. Xws li:
Kev lag luam tub yees tshuab (supermarkets, khw muag khoom yooj yim)
Industrial tub yees
Thauj tub yees (tsheb thauj khoom, tsheb thauj khoom, thawv)
Qee lub tshuab cua txias

Qhov zoo

Efficiency: R404A muaj cov tub yees ua haujlwm zoo, ua rau nws tsim nyog rau kev lag luam kev lag luam uas qhov kev ua tau zoo thiab kev ntseeg siab yog qhov tseem ceeb.
Compatibility: Nws yog sib xws nrog feem ntau cov ntaub ntawv thiab lubricants siv nyob rau hauv lub tub yees tshuab tsim rau HFC refrigerants.
Tsis muaj Ozone Depletion: Tsis zoo li qub CFCs thiab HCFCs, R404A tsis ua rau ozone txheej depletion.
