Kuza kufunyanwa ezinye eziza kutshintsha iifriji zesizukulwana sesibini nesesithathu!
Ngomhla we-15 kweyoMsintsi ngo-2021, "uLungiso lwaseKigali kwiProtocol yaseMontreal kwiZinto eziCima i-Ozone Layer" lwaqala ukusebenza eTshayina. Ngokwe-"Montreal Protocol", isizukulwana sesibini se-refrigerant HCFC siza kuyeka ukusetyenziswa ngo-2030. Olu hlengahlengiso lufuna ukuba ngo-2050, ukusetyenziswa kwee-HFC kwihlabathi liphela kwehle malunga ne-85%.
Esi sisiganeko esibalulekileyo kwinkqubo yokuphelisa ukusetyenziswa kwe-refrigerant, kwaye sikwathumela uphawu olukhulu lwezopolitiko lokuba uluntu lwamazwe ngamazwe luzimisele ukuphelisa ukusetyenziswa kwe-HFCs.
Kwangaxeshanye, ngokumiselwa kwenjongo yasekhaya "ye-dual-carbon" kunye nokuphunyezwa kancinci kancinci komgaqo-nkqubo wolawulo lwe-refrigerant HFCs yesizukulwana sesithathu, kungxamisekile ukufunda nge-HCFC, izinto ezithatha indawo ye-HFCs kunye nobuchwepheshe obunxulumene noko.
I-refrigerant ingena kwixesha lexabiso eliphantsi le-GWP, kwaye ingxaki yokutsha ayinakutyeshelwa!
Ngokubanzi, ukusetyenziswa kweefriji ezinokutsha ezinexabiso eliphantsi le-GWP endaweni ye-HCFC kunye nezinye iigesi ezine-fluorine kuthathwa njengesisombululo esisebenzayo nesingabizi kakhulu. Nangona kunjalo, izifundo zibonise ukuba iifriji zemveli azifane zihlangabezane nazo zonke iimfuno zeefriji zexesha elizayo ze-GWP ephantsi, ukhuseleko, ukusebenza kwe-thermodynamic kunye nokusebenza kokusingqongileyo ngaxeshanye.
Ngamanye amazwi, amaxabiso amaninzi aphantsi e-GWP ayatsha!
Umgangatho wesizwe "Indlela Yokubala Iinombolo Zefriji NokuHlela Ukhuseleko" GB/T 7778-2017 wahlula ubuthi beefriji kwiCandelo A (ubuthi obuphantsi obungapheliyo) kunye neCandelo B (ubuthi obuphezulu obungapheliyo), kwaye ukutsha kwahlulwe kwiCandelo 1 (Akukho kusasazeka kwelangabi), iCandelo 2L (kunokwenzeka kancinci), iCandelo 2 (elinokwenzeka), kunye neCandelo 3 (elinokutsha kwaye liqhuma). Ngokutsho kwe-GB/T 7778-2017, ukhuseleko lweefriji lwahlulwe kwiindidi ezisi-8, ezizezi: A1, A2L, A2, A3, B1, B2L, B2, kunye ne-B3. Phakathi kwazo, i-A1 yeyona ikhuselekileyo kwaye i-B3 yeyona iyingozi kakhulu.
Ungayisebenzisa njani i-A2L HFO refrigerant ngokukhuselekileyo nangokufanelekileyo?
Nangona ii-air conditioner zasekhaya, ii-air conditioner eziphakathi kunye nezinye izixhobo zokukhenkcisa ziye zavavanywa ukuze zibone ukuba zisebenza kakuhle na kumzi-mveliso, ixabiso eliyireferensi yentlawulo ye-refrigerant liyaboniswa. Nangona kunjalo, iiyunithi ezininzi ezinkulu ze-air conditioner eziphakathi kunye nee-industrial chillers kufuneka zizaliswe nge-refrigerant kwindawo, njengoko kunjalo ngee-air conditioner zasekhaya, izixhobo zefriji, indawo yokugcina izinto ebandayo, njl. ngexesha lenkqubo yokulungisa.
Ngaphezu koko, ngenxa yeentlobo ezahlukeneyo zee-evaporators ezisetyenziswa kwezinye izixhobo, itshaja ye-refrigerant yahlukile. Ukongeza kwindawo yokulungisa nokufakela, ngenxa yeemeko ezilinganiselweyo, abasebenzi abaninzi bokulungisa bahlawulisa i-refrigerant ngokusekelwe kumava. Ukongeza, eli shishini likwanovelwano kakhulu kumba wokutsha kwe-refrigerant.
Ngokusekelwe koku, iChemours iqalise i-R1234yf, i-R454A, i-R454B, i-R454C kunye nezinye iifriji ze-A2L ezitsha kancinci, ezine-GWP ephantsi, kwaye izibophelele ekukhuthazeni uyilo lwenkqubo kunye noqeqesho lwesayensi oludumileyo ukusombulula iingozi zokutsha.
Inqanaba lokhuseleko le-A2L lineempawu zetyhefu ephantsi (A) kunye nokutsha okubuthathaka (2L). Iifriji ezininzi ze-A2L HFO zineempawu ze-GWP eziphezulu kunye neempawu ze-GWP eziphantsi, kwaye zilungele indawo yesizukulwana sangaphambili seefriji ze-HFC. Iimveliso ze-A2L azisetyenziswa kakhulu kwimarike yamazwe ngamazwe kuphela, kodwa iinkampani ezininzi zasekhaya nazo zikhawulezise isantya sokuphucula nokwazisa olu hlobo lutsha lwefriji kwizicelo zemveliso. Umzekelo, iJohnson Controls isebenzisa i-Oteon™ XL41 (R-454B) kwi-York ® YLAA scroll chiller yayo kwimarike yaseYurophu; iCarrier ikwakhetha i-R-454B (oko kukuthi, Njenge-refrigerant yayo ephambili ye-GWP ephantsi, iCarrier iya kusebenzisa i-R-454B kwiimveliso zayo ze-HVAC zokuhlala kunye nezentengiso ezilula ezithengiswa eMntla Melika ukususela ngo-2023. Buyisela i-R-410A.
