ua ntej:

1. R404A yog qhov sib xyaw ntawm HFC125, HFC-134a thiab HFC-143, qhov piv yog R404A=44 feem pua ​​R125 ntxiv rau 4 feem pua ​​R134A ntxiv rau 52 feem pua ​​143A. Nws yog cov roj tsis muaj xim nyob rau hauv chav tsev kub thiab cov kua tsis muaj xim thiab pob tshab hauv nws lub siab. R-404A yog tsim rau cov khoom siv tub yees tshiab, cov khoom siv tub yees tsheb thauj mus los lossis cov khoom siv rov ua dua tshiab ntawm qhov nruab nrab thiab qis. Ze tshaj rau R-502, cov tub yees no haum rau txhua qhov chaw uas R-502 tuaj yeem ua haujlwm tau zoo.

2. R134a yog cov tub yees siv rau hauv cov tub yees me me thiab lub tshuab cua txias. Txij li thaum xyoo 1990, nws tau pib hloov R-12, uas ua rau muaj kev phom sij ntau dua rau ib puag ncig, thiab cov khoom siv tub yees qub R-12 tau hloov kho los siv 1,1,1,{{8} }Tetrafluoroethane hmoov. Tsis tas li ntawd, nws kuj tseem siv tau los ua tus neeg sawv cev foaming, tus neeg saib xyuas tu, tshuaj (xws li bronchodilator) propellant, wine corkscrew, plua plav collector thiab dehumidification ntawm compressed cua, thiab lwm yam.
