U-Emerson webinar unikeze ukuhlaziywa kwimigangatho emitsha malunga nokusetyenziswa kwe-A2Ls
Njengoko sisondela kwisiqingatha sesiqingatha sonyaka, ishishini le-HVACR lijonge ngocoselelo njengoko amanyathelo alandelayo enqanaba lehlabathi leefriji ze-hydrofluorocarbon (HFC) evela elundini.Iithagethi ezisakhulayo ze-decarbonization ziqhuba ukuncipha kokusetyenziswa kwee-HFC ze-GWP eziphezulu kunye nokutshintshela kwisizukulwana esilandelayo, iindlela ezizezinye zezikhenkcisi ze-GWP ezisezantsi.
Kwi-Webinar ye-E360 yakutsha nje, uRajan Rajendran, usekela-mongameli wehlabathi jikelele ka-Emerson wozinzo, kwaye ndanikezela ngohlaziyo malunga nobume bemimiselo yefriji kunye neempembelelo zabo kwishishini lethu.Ukususela kumanyathelo okunciphisa alawulwa ngurhulumente kunye norhulumente ukuya ekuphuhliseni imigangatho yokhuseleko elawula ukusetyenziswa kweefriji ze-A2L "ezinokutsha okuphantsi", sinikeze umboniso wembonakalo yomhlaba yangoku kwaye saxoxa ngezicwangciso zokuphumeza i-HFC yangoku neyexesha elizayo kunye nokunciphisa i-GWP.
UMTHETHO WENJONGO
Mhlawumbi oyena mqhubi ubalulekileyo kwi-US HFC phasedown yaba kukupasiswa kuka-2020 kweAmerican Innovation and Manufacturing Act (AIM) Act kunye negunya elinika iArhente yoKhuseleko lokuSingqongileyo (EPA).I-EPA imisela isicwangciso-qhinga esisikela umda kokubini unikezelo kunye nemfuneko yee-HFC ze-GWP eziphezulu ngokweshedyuli yokwehliswa kwenkqubo emiselwe siSihlomelo saseKigali kwiSivumelwano saseMontreal.
Inyathelo lokuqala liqale kulo nyaka ngokuncipha kokusetyenziswa nokuveliswa kwee-HFC nge-10%.Inyathelo elilandelayo liya kuba kukuncitshiswa kwe-40%, okuya kusebenza ngo-2024 - ibhentshi emele ukwehla okuphambili okuvakala kuwo wonke amacandelo e-US HVACR.Imveliso yefriji kunye nezabelo zokungenisa elizweni zisekelwe kumlinganiselo we-GWP wefriji ethile, ngaloo ndlela ixhasa ukuveliswa kwemveliso yeefriji ze-GWP ezisezantsi kunye nokuncipha kokufumaneka kwee-HFC ze-GWP eziphezulu.Ke ngoko, umthetho wonikezelo kunye nemfuno uya kuqhuba amaxabiso e-HFC kwaye ukhawulezise utshintsho kwiinketho ezisezantsi ze-GWP.Njengoko sele sibonile, ishishini lethu sele lijongene nokunyuka kwamaxabiso e-HFC.
Kwicala lemfuno, i-EPA iphakamisa ukuqhuba ukusetyenziswa kwe-GWP ephezulu ye-HFC kwizixhobo ezitsha ngokubeka imida emitsha ye-GWP yefriji kwifriji yokuthengisa kunye nezicelo zomoya.Oku kunokukhokelela ekubuyiselweni koMgaqo-nkqubo oMtsha oBalulekileyo weeNdlela ezizezinye (SNAP) imithetho yama-20 kunye ne-21 kunye/okanye ukwaziswa kwezindululo zeSNAP ezijolise ekwamkeleni iinketho ezintsha ze-GWP eziphantsi njengoko zifumaneka ukuba zisetyenziswe kubuchwephesha obusakhulayo befriji.
Ukunceda ukufumanisa ukuba loo mida emitsha ye-GWP iya kuba yintoni, abaxhasi be-AIM Act bacele igalelo loshishino ngezikhalazo, ezininzi zazo sele zithathelwe ingqalelo i-EPA.Ngoku i-EPA isebenza kwiidrafti zokwenziwa kwemithetho ecetywayo, esinethemba lokuyibona kulo nyaka.
Isicwangciso se-EPA sokunciphisa imfuno ye-HFC sikwasebenza nasekunikezelweni kwenkonzo kwezixhobo ezikhoyo.Lo mba ubalulekileyo wenxaki yemfuno ugxile ikakhulu ekuncitshisweni kokuvuza, ukuqinisekiswa, kunye nokunika ingxelo (ngokufanayo nesindululo seCandelo lama-608 le-EPA, ekhokele izizukulwana zangaphambili zokwehla kwezikhenkcezisi).I-EPA isebenzela ukubonelela ngeenkcukacha ezinxulumene nolawulo lwe-HFC, olunokubangela ukubuyiselwa kweCandelo 608 kunye/okanye inkqubo entsha yokubuyisela i-HFC.
IBHOKISI YEZIXHOBO YE-HFC PHASEDOWN
Njengoko uRajan ecacise kwiwebinar, i-phasedown ye-HFC ekugqibeleni ijolise ekunciphiseni ukukhutshwa kwegesi ye-greenhouse (GHG) ngokusekelwe kwiimpembelelo zabo ezithe ngqo kunye nezingathanga ngqo zokusingqongileyo.Ukukhutshwa okuthe ngqo kubhekiselele kumandla okuba izikhenkcezi zivuze okanye zikhutshelwe emoyeni;ukukhutshwa okungathanga ngqo kubhekiselele kusetyenziso lwamandla lwefriji ehambelanayo okanye izixhobo zokupholisa umoya (eqikelelwa ukuba ngamaxesha angama-10 impembelelo yokukhutshwa ngokuthe ngqo).
Ngokoqikelelo lwe-AHRI, i-86% yokusetyenziswa kwefriji iyonke ivela kwisikhenkcisi, kwisimo somoya, kunye nesixhobo sempompo yobushushu.Kuloo nto, yi-40% kuphela enokuthi ifakwe ekuzaliseni izixhobo ezitsha, ngelixa i-60% isetyenziselwa ukugqithisa iinkqubo eziye zavuza ngokuthe ngqo kwisikhenkcisi.
URajan wabelane ukuba ukulungiselela inyathelo elilandelayo utshintsho ekuncitshisweni kwe-HFC ngo-2024 kuya kufuna ukuba imboni yethu isebenzise izicwangciso ezingundoqo kwi-HFC phasedown toolbox, ezifana nolawulo lwefriji kunye noyilo lwezixhobo zokusebenza ezifanelekileyo.Kwiinkqubo esele zikho, oku kuya kuthetha ukonyuka kokugxila kugcino ukuze kuncitshiswe zombini ukuvuza okuthe ngqo kunye neempembelelo ezingangqalanga zokusingqongileyo zokungasebenzi kakuhle kwenkqubo kunye nokusebenza kakuhle kwamandla.Izindululo kwiinkqubo ezikhoyo ziquka:
Ukubona, ukunciphisa, kunye nokuphelisa ukuvuza kwefriji;
Ukubuyisela kwakhona kwisibandisi esisezantsi se-GWP kwiklasi enye (A1), enemeko engcono kakhulu yokukhetha izixhobo ezikwa-A2L-ready;kwaye
Ukufumana kunye nokubuyisela kwakhona ifriji ukuze isetyenziswe enkonzweni (ungaze ukhuphe ifriji okanye ukhulule emoyeni).
Kwizixhobo ezitsha, uRajan ucebise ukuba kusetyenziswe eyona ndlela iphantsi ye-GWP kwaye kwamkele ubugcisa obuvelayo benkqubo yesikhenkcezisi obusebenzisa iintlawulo ezisezantsi zefriji.Njengoko kuye kwaba njalo kwezinye iinketho zokuhlawulela eziphantsi - ezifana ne-self-contained, iinkqubo ze-R-290 - injongo yokugqibela kukufezekisa umthamo omkhulu wenkqubo usebenzisa ubuncinci bentlawulo yefriji.
Kuzo zombini izixhobo ezitsha kunye nesele zikho, kubalulekile ukugcina onke amacandelo, izixhobo kunye neenkqubo ngokuhambelana neemeko ezifanelekileyo zoyilo, kubandakanywa ngexesha lofakelo, ugunyaziso kunye nokusebenza okuqhelekileyo.Ukwenza oko kuya kuphucula ukusebenza kakuhle kwamandla kunye nokusebenza ngelixa kuncitshiswa iimpembelelo ezingathanga ngqo.Ngokusebenzisa ezi zicwangciso kwizixhobo ezitsha nezikhoyo, sikholelwa ukuba ishishini lethu linokufikelela kunciphiso lwe-HFC ngaphantsi kwe-2024 phasedown - kunye nokunciphisa i-70% ecwangciselwe i-2029.
A2L UKUPHUMA
Ukufezekisa ukunciphisa okufunekayo kwe-GWP kuya kufuna ukusetyenziswa kweefriji ze-A2L ezivelayo ezinomlinganiselo "wokutsha ophantsi".Ezi zikhetho-ezinokuthi zibe phakathi kwezo ziza kuvunywa kungekudala yi-EPA-zibe ngumxholo wemigangatho yokhuseleko eguqukayo ngokukhawuleza kunye neekhowudi zokwakha ezenzelwe ukuba zisebenzise ngokukhuselekileyo kwifriji yokuthengisa.Ukusuka kwindawo yokujonga indawo yefriji, uRajan wachaza ukuba zeziphi iifriji ze-A2L eziphuhliswayo kunye nendlela ezithelekisa ngayo nabangaphambili be-HFC ngokwe-GWP kunye nokulinganiswa kwamandla.
