Sekumbovu ukuba kufumaneke izikhenkcisi ezithatha indawo zesizukulwana sesibini nesesithathu!
Ngomhla we-15 kuSeptemba, ngo-2021, "uLungiso lwaseKigali kwiSivumelwano saseMontreal kwiZinto eziNcisa i-Ozone Layer" saqalisa ukusebenza eTshayina.Ngokutsho kwe "Montreal Protocol", i-HCFC yesizukulwana sesibini efrijini iya kuyeka ukusetyenziswa ngo-2030. Ukulungiswa kufuna ukuba ngo-2050, ukusetyenziswa kwe-HFCs yehlabathi kuya kuhla malunga ne-85%.
Esi sisiganeko esibalulekileyo kwinkqubo yokuphelisa isikhenkcezisi, kwaye ikwathumela umqondiso omkhulu wezopolitiko wokuba uluntu lwamazwe ngamazwe luzimisele ukukuphelisa ukusetyenziswa kwee-HFC.
Kwangaxeshanye, kunye nokusekwa yasekhaya "dual-carbon" ekujoliswe kunye nokuphunyezwa ngokuthe ngcembe umgaqo-nkqubo yolawulo HFCs refrigerant kwisizukulwana sesithathu, kungxamisekile ukufunda HCFC, HFCs izinto endaweni kunye nobuchwepheshe ezinxulumene.
Ifriji ingena kwixesha lexabiso eliphantsi le-GWP, kwaye ingxaki yokutsha ayinakuhoywa!
Ngokuqhelekileyo, ukusetyenziswa kweefriji ezivuthayo kunye namaxabiso aphantsi e-GWP ukutshintsha i-HCFC kunye nezinye iigesi ezine-fluorine kuthathwa njengesisombululo esisebenzayo nesisezantsi.Nangona kunjalo, uphando lubonise ukuba iifriji zendabuko azifane zihlangabezane nazo zonke iimfuno zeefriji ezizayo kwi-GWP ephantsi, ukhuseleko, ukusebenza kwe-thermodynamic kunye nokusebenza kokusingqongileyo ngexesha elifanayo.
Ngamanye amazwi, amanani amaninzi aphantsi e-GWP ayatsha!
Umgangatho wesizwe "iNdlela yokuBala i-Refrigerant kunye noHlelo loKhuseleko" i-GB / T 7778-2017 yahlula ubuthi befriji kwi-Class A (i-toxicity ephantsi engapheliyo) kunye ne-Class B (i-toxicity ephezulu engapheliyo), kwaye ukutsha kuhlelwe kwi-Class 1 (Akukho ukusasazwa komlilo ), iKlasi 2L (enokwenzeka ngokubuthathaka), iClass 2 (enokwenzeka), kunye neClass 3 (enokutsha kunye nokuqhuma).Ngokutsho kwe-GB / T 7778-2017, ukhuseleko lweefriji luhlulwe kwiindidi ze-8, ezizezi: A1, A2L, A2, A3, B1, B2L, B2, kunye ne-B3.Phakathi kwabo, i-A1 yeyona nto ikhuselekileyo kwaye i-B3 yeyona nto iyingozi kakhulu.
Indlela yokusebenzisa iA2L HFO efrijini ngokukhuselekileyo nangempumelelo?
Nangona i-air conditioners yasekhaya, i-air conditioners ephakathi kunye nezinye izixhobo zefriji zivavanyelwe ukusebenza kwifektri, ixabiso lereferensi yentlawulo yefriji ibonakalisiwe.Nangona kunjalo, ezininzi iiyunithi ezinkulu zomoya ophakathi kunye ne-industrial chillers kufuneka zizaliswe ngefriji kwi-site, njengoko kwenza i-air-conditioner yasekhaya, izixhobo zefriji, ukugcinwa okubandayo, njl. ngexesha lokugcinwa.
Ngaphezu koko, ngenxa yeentlobo ezahlukeneyo ze-evaporator ezisetyenziswa kwezinye izixhobo, intlawulo yefriji yahlukile.Ukongeza kwindawo yokugcina kunye nofakelo, ngenxa yeemeko ezilinganiselweyo, abasebenzi abaninzi bokulondoloza bahlawula ifriji ngokusekelwe kumava.Ukongeza, ishishini likwanovelwano kakhulu kumbandela wokutsha kwefriji.
Ngokusekelwe koku, iChemours isungule i-R1234yf, i-R454A, i-R454B, i-R454C kunye nezinye i-A2L enokutsha buthathaka, iifriji ze-GWP eziphantsi, kwaye izibophelele ekukhuthazeni uyilo lwenkqubo kunye noqeqesho lwenzululwazi oludumileyo ukusombulula imingcipheko yokutsha.
Inqanaba lokhuseleko le-A2L lineempawu zobuthi obuphantsi (A) kunye nokutsha okubuthathaka (2L).Iifriji ezininzi ze-A2L HFO zinemisebenzi ephezulu kunye neempawu eziphantsi ze-GWP, kwaye zithatha indawo efanelekileyo yesizukulwana sangaphambili sefriji ye-HFC.Iimveliso ze-A2L azisetyenziswanga ngokubanzi kwiimarike zamazwe ngamazwe, kodwa iinkampani ezininzi zasekhaya ziye zakhawulezisa isantya sokuphucula kunye nokwazisa olu hlobo olutsha lwefriji kwizicelo zemveliso.Umzekelo, i-Johnson Controls isebenzisa i-Oteon™ XL41 (R-454B) kwi-York ® YLAA yokuskrola i-chiller kwimarike yaseYurophu;I-Carrier iphinda ikhethe i-R-454B (oko kukuthi njenge-refrigerant yayo ephantsi ye-GWP, i-Carrier iya kusebenzisa i-R-454B kwindawo yayo yokuhlala ye-tubular kunye ne-HVAC yokuthengisa ukukhanya kweemveliso ezithengiswa eMntla Melika ukusuka kwi-2023.
