Tetrafluoroethane R134A (C2H2F4)

Technical Parameter:

R134a (1,1,1,2-tetrafluoroethane) ndiyo yakanyanya kushandiswa yepakati nepasi tembiricha yakadzika zvakatipoteredza. R-134a iri firiji iyo isina maatomu echlorine, haina kukuvadza ozone layer, uye ine yakanaka yekuchengetedza mashandiro (isingatsve, isingaputi, isina chepfu, isingatsamwisi, isinga gwinyise), kutonhora kwayo kugona uye kushanda kwayo Iri padhuze neR-12 (dichlorodifluoromethane, Freon), saka inoonekwa seyakanakisa kwenguva refu imwe nzira firiji. R-134a parizvino inozivikanwa pasi rose senzvimbo yakanakira zvakatipoteredza yeR-12. Izvo hazviparadze ozone layer zvachose. Iyo firiji ine zvakatipoteredza inozivikanwa uye inokurudzirwa nenyika zhinji pasi rese. Iyo zvakare iri yazvino yakakomberedza nharaunda ine hushamwari firiji. Inoshandiswa zvakanyanya mukutanga kuisirwa uye kugadzirisa kwefriji nyowani nemidziyo yemhepo-kutonhodza. R134a ine chepfu yakadzika kwazvo, isingabatike mumhepo, uye ine chikamu chekuchengetedza cheA1, iri firiji yakachengeteka kwazvo. R134a inonyanya kushandiswa muminda mizhinji, inosanganisira: mafiriji, mafiriza, magadzirirwo emvura, mota dzemuchina, maekisesaizi epakati, ekudzikisira mweya, kutonhodza kutonhora, firiji yekutengesa, muchina wemvura yechando, machini echando echando, michina yekuisa mufiriji uye mimwe midziyo yefiriji. Aerosol propellant, medical aerosol, insecticide propellant, polymer (plastiki) yemuviri inopupuma furo mumiririri, uye magnesium alloy inodzivirira gasi, nezvimwe. R-134a inogona kushandiswa zvakanyanya sefriji mumotokari mhepo mahara, mafiriji, epakati mhepo maekisesaizi, ekutengesa firiji uye zvimwe maindasitiri, uye inogona kushandiswa mumushonga, mishonga yekuuraya zvipuka, zvipoda, uye maindasitiri ekuchenesa. Iko kugadzikana kwemakemikari kweR134a kwakanaka kwazvo. Nekudaro, nekuti kusimba kwemvura kwaro kwakakwirira kupfuura iyo yeR22, haina kunaka kune iyo firiji system. Kunyangwe paine shoma mvura, inozogadzira acid, carbon dioxide kana carbon monoxide pasi pechiito chekuzora mafuta. Ngura kana "mhangura yakakwenenzverwa" inogadzirwa, saka R134a inoda kuomeswa kwepamusoro uye kuchenesa kwechirongwa. R134a haina chemakemikari anoita nesimbi, simbi, mhangura, aruminiyamu nezvimwe simbi, uye inongova nezviito zvishoma pane zinc.

Kushanda:

Refrigerant:

Tetrafluoroethane ndiyo imwe nzira huru yeCFC-r12, inoshandiswa zvakanyanya munzvimbo zhinji yefriji yakaita sefiriji, firiji, mudziyo wemvura, mota inodziya mweya, yepakati mhepo-kutonhodza, muchina wechando, muchina wekupidisa firiji nezvimwe.

TherKumwe kushandisa:

Iyo inoshandiswawo kune eerosol propellant, ekurapa maekisesaizi uye mishonga yezvipembenene aerosol; inoshandiswa se polymer (plastiki) yemuviri inopupuma furo mumiriri uye magnesium alloy inodzivirira gasi.
