U-Emerson webinar unikeze isibuyekezo emazingeni amasha mayelana nokusetshenziswa kwama-A2L
Njengoba sisondela engxenyeni emaphakathi yonyaka, imboni ye-HVACR ibhekisisa njengoba izinyathelo ezilandelayo zokwehla komhlaba wonke kweziqandisi ze-hydrofluorocarbon (HFC) zivela emkhathizwe.Okuhlosiwe okusafufusa kwe-decarbonization kunciphisa ukusetshenziswa kwama-GWP HFC aphezulu kanye nokushintshela esizukulwaneni esilandelayo, ezinye iziqandisi ze-GWP eziphansi.
Ku-Webinar ye-E360 yakamuva, u-Rajan Rajendran, iphini likamongameli womhlaba wonke ka-Emerson wokusimama, futhi nginikeze isibuyekezo ngesimo semithetho yesiqandisi kanye nomthelela wayo embonini yethu.Kusukela ezinhlelweni zokwehliswa eziholwa uhulumeni kanye nohulumeni kuya kumazinga okuphepha athuthukayo alawula ukusetshenziswa kweziqandisi ze-A2L “ezivutha kancane”, sinikeze umbono omfishane wokuma kwezwe kwamanje futhi saxoxisana ngamasu okuzuza ukuncishiswa kwe-HFC yamanje neyesikhathi esizayo ne-GWP.
UMTHETHO WENHLOSO
Mhlawumbe umshayeli obaluleke kakhulu e-US HFC yehla kwakuwukuphasiswa kuka-2020 kwe-American Innovation and Manufacturing (AIM) Act kanye negunya elinikeza i-Environmental Protection Agency (EPA).I-EPA isungula isu elikhawulela kokubili ukuhlinzekwa kanye nesidingo sama-HFC e-GWP aphezulu ngokohlelo lokwehliswa olubekwe yiSichibiyelo sase-Kigali sePhrothokholi yaseMontreal.
Isinyathelo sokuqala siqale kulo nyaka ngokuncipha ngo-10% kokusetshenziswa nokukhiqizwa kwama-HFC.Isinyathelo esilandelayo kuzoba ukwehliswa ngo-40%, okuzoqala ukusebenza ngo-2024 - ibhentshimark emele ukwehla okukhulu kokuqala okuzwakala kuyo yonke imikhakha ye-US HVACR.Ukukhiqizwa kwesiqandisi kanye nezabelo zokungenisa ezweni kusekelwe esilinganisweni se-GWP sesiqandisi esithile, ngaleyo ndlela sisekela ukukhiqizwa okukhulayo kweziqandisi ezine-GWP ephansi kanye nokuncipha kokutholakala kwama-HFC e-GWP aphezulu.Ngakho-ke, umthetho wokuhlinzeka nesidingo uzokhuphula amanani e-HFC futhi usheshise ukushintshela ezinkethweni eziphansi ze-GWP.Njengoba sesibonile, imboni yethu isivele ibhekene nezintengo ezikhuphukayo ze-HFC.
Ngasohlangothini lwesidingo, i-EPA ihlongoza ukwehlisa ukusetshenziswa kwe-GWP HFC ephezulu emishinini emisha ngokubeka imikhawulo emisha yesiqandisi ye-GWP esiqandisini sezentengiselwano kanye nezicelo zesimo somoya.Lokhu kungase kuholele ekubuyiselweni kwemithetho yayo engu-20 no-21 yeNqubomgomo Entsha Ebalulekile Yezinye izindlela (SNAP) kanye/noma ukwethulwa kweziphakamiso ze-SNAP okuhloswe ngazo ukugunyaza izinketho ezintsha ze-GWP ephansi njengoba sezitholakala ukuze zisetshenziswe kubuchwepheshe beziqandisi obusafufusa.
Ukusiza ukunquma ukuthi leyo mikhawulo emisha ye-GWP izoba yini, abaxhasi boMthetho we-AIM bacele ukufakwa kwemboni ngezikhalazo, ezimbalwa zazo i-EPA esezicabangile.I-EPA njengamanje isebenzela uhlaka lokwenziwa kwemithetho ehlongozwayo, esethemba ukuthi sisazoyibona kulo nyaka.
Isu le-EPA lokukhawulela isidingo se-HFC liyasebenza nasekuhlinzekweni kwezisetshenziswa ezikhona.Lesi sici esibalulekile se-equation yesidingo sigxile kakhulu ekwehliseni ukuvuza, ukuqinisekiswa, kanye nokubika (okufana nesiphakamiso seSigaba 608 se-EPA, esiqondise izizukulwane ezedlule zokwehla kweziqandisi).I-EPA isebenzela ukuhlinzeka ngemininingwane ehlobene nokuphathwa kwe-HFC, okungase kuphumele ekubuyiselweni kweSigaba 608 kanye/noma uhlelo olusha lonke lokufuna kabusha i-HFC.
Ibhokisi lamathuluzi le-HFC PHASEDOWN
Njengoba u-Rajan echaza ku-webinar, i-phasedown ye-HFC ekugcineni ihloselwe ukunciphisa ukukhishwa kwegesi ebamba ukushisa (GHG) ngokusekelwe emithelela yabo eqondile nengaqondile kwezemvelo.Ukukhishwa kwegesi okuqondile kubhekisela emandleni okuthi iziqandisi zivuze noma zidedelwe emkhathini;ukukhishwa okungaqondile kubhekisela ekusetshenzisweni kwamandla kwesiqandisi esihlobene noma okokusebenza komoya (okulinganiselwa ukuthi kuphindwe izikhathi ezingu-10 umthelela wokukhishwa okuqondile).
Ngokwezilinganiso ezivela ku-AHRI, u-86% wesamba esisetshenziswa esiqandisini sisuka esiqandisini, esifaka umoya, nempahla yephampu yokushisa.Kulokho, ama-40% kuphela angabalelwa ekugcwaliseni imishini emisha, kuyilapho u-60% usetshenziselwa ukwethula amasistimu abenokuvuza okuqondile kwesiqandisi.
U-Rajan wabelane ngokuthi ukulungiselela isinyathelo esilandelayo soshintsho lokwehliswa kwe-HFC ngo-2024 kuzodinga ukuthi imboni yethu isebenzise amasu abalulekile ebhokisini lamathuluzi le-HFC lesigaba sokwehlisa, njengokuphatha isiqandisi nezinqubo ezingcono kakhulu zokuklama imishini.Ezinhlelweni ezikhona, lokhu kuzosho ukwanda kokugxila ekunakekeleni ukuze kuncishiswe kokubili ukuvuza okuqondile kanye nemithelela engaqondile yezemvelo yokusebenza kabi kwesistimu nokonga kwamandla.Izincomo zamasistimu akhona zifaka:
Ukubona, ukunciphisa, kanye nokuqeda ukuvuza kwesiqandisi;
Ukufaka kabusha isiqandisi esine-GWP ephansi ekilasini elifanayo (A1), esinesimo esingcono kakhulu sokukhetha okokusebenza naso esilungele i-A2L;futhi
Ukuthola kanye nokubuyisela isiqandisi ukuze sisetshenziswe enkonzweni (ungalokothi usikhiphele isiqandisi noma usikhiphele emkhathini).
Emishinini emisha, u-Rajan uncome ukusebenzisa enye indlela ye-GWP ephansi kakhulu futhi kwamukele ubuchwepheshe obusafufusa besistimu yesiqandisi obunyusa amashaji aphansi wesiqandisi.Njengoba kuye kwenzeka kwezinye izinketho zokukhokhiswa okuphansi - njengezinhlelo ezizimele, ze-R-290 - umgomo wokugcina uwukuthola umthamo omkhulu wesistimu usebenzisa inani elincane lenkokhelo yesiqandisi.
Kuzo zombili izinto ezisetshenziswayo ezintsha nezikhona, kubalulekile ukuthi ngaso sonke isikhathi unakekele zonke izingxenye, okokusebenza, namasistimu ngokuhambisana nezimo ezifanele zokuklama, okuhlanganisa phakathi nokufakwa, ukugunyazwa nokusebenza okuvamile.Ukwenza kanjalo kuzothuthukisa ukusebenza kahle kwamandla nokusebenza ngenkathi kunciphisa imithelela engaqondile.Ngokusebenzisa lawa maqhinga ezintweni ezintsha nezikhona, sikholelwa ukuthi imboni yethu ingafinyelela ekwehliseni i-HFC ngaphansi kwesigaba sokwehla sika-2024 - kanye nokwehliswa okungama-70% okuhlelelwe u-2029.
I-A2L EZIPHUMAYO
Ukuzuza ukwehliswa okudingekayo kwe-GWP kuzodinga ukusetshenziswa kweziqandisi ezivelayo ze-A2L ezinesilinganiso "sokuvutha okuphansi".Lezi zindlela ezihlukile - futhi okungenzeka zibe phakathi kwalezo ezizogunyazwa maduze yi-EPA - bekuyisihloko samazinga okuphepha avela ngokushesha namakhodi wokwakha aklanyelwe ukunika amandla ukusetshenziswa kwawo okuphephile esiqandisini sezentengiselwano.Uma ubuka indawo enesiqandisi, u-Rajan uchaze ukuthi yiziphi iziqandisi ze-A2L ezithuthukiswayo nokuthi ziqhathaniswa kanjani nabangaphambi kwe-HFC bazo ngokwe-GWP kanye nezilinganiso zomthamo.
