Malamulo a Refrigerant Akupitiriza Kusintha

Emerson webinar adapereka zosintha pamiyezo yatsopano yokhudza kugwiritsa ntchito ma A2L

Pamene tikuyandikira theka la chaka, makampani a HVACR akuyang'anitsitsa pamene masitepe otsatirawa akuwonekera m'chizimezime m'mafiriji a hydrofluorocarbon (HFC) padziko lonse lapansi.Zolinga zomwe zikuchulukirachulukira zikuyendetsa kuchepetsedwa kwa kugwiritsa ntchito ma GWP HFC apamwamba kwambiri komanso kusintha kwa m'badwo wotsatira, njira zochepetsera mufiriji za GWP.
Mu E360 Webinar yaposachedwa, Rajan Rajendran, wachiwiri kwa purezidenti wapadziko lonse wa Emerson wokhazikika, ndipo ine tidapereka zosintha pamikhalidwe ya malamulo afiriji ndi momwe zimakhudzira mafakitale athu.Kuchokera pamachitidwe a gawo lotsogozedwa ndi boma ndi boma mpaka kusintha miyezo yachitetezo yomwe imayang'anira kugwiritsa ntchito mafiriji "otsika oyaka" A2L, tidapereka chithunzithunzi cha malo omwe alipo ndikukambirana za njira zopezera kuchepetsa kwapakali pano komanso kwamtsogolo kwa HFC ndi GWP.

AIM ACT
Mwina dalaivala wofunikira kwambiri mu gawo la US HFC chinali kudutsa kwa 2020 kwa American Innovation and Manufacturing (AIM) Act ndi ulamuliro womwe umapereka ku Environmental Protection Agency (EPA).EPA ikukhazikitsa njira yomwe imachepetsa kuperekedwa ndi kufunikira kwa ma HFC a GWP apamwamba malinga ndi ndondomeko yotsika yomwe yakhazikitsidwa ndi Kigali Amendment to Montreal Protocol.
Gawo loyamba lidayamba chaka chino ndikuchepetsa kugwiritsa ntchito ndi kupanga ma HFC ndi 10%.Chotsatira chidzakhala kuchepetsedwa ndi 40%, komwe kudzachitika mu 2024 - chizindikiro chomwe chikuyimira kutsika kwakukulu koyamba m'magawo onse a US HVACR.Kupanga firiji ndi kuitanitsa katundu kumachokera ku chiwerengero cha GWP cha firiji yeniyeni, potero kuthandizira kuwonjezereka kwa mafiriji otsika a GWP ndi kuchepa kwa kupezeka kwa ma HFC apamwamba a GWP.Chifukwa chake, lamulo lakupereka ndi kufunikira likweza mitengo ya HFC ndikufulumizitsa kusintha kwa zosankha za GWP zotsika.Monga tawonera, makampani athu akukumana kale ndi mitengo ya HFC.
Kumbali yofunikira, EPA ikuganiza zochepetsera kugwiritsidwa ntchito kwa GWP HFC kwapamwamba kwambiri pazida zatsopano poika malire atsopano a firiji a GWP mufiriji zamabizinesi ndi ntchito zoziziritsira mpweya.Izi zitha kubweretsa kubwezeretsedwa kwa malamulo ake a 20 ndi 21 ndi / kapena kukhazikitsidwa kwa malingaliro a SNAP omwe cholinga chake ndi kuvomereza njira zatsopano za GWP zotsika pamene zipezeka kuti zigwiritsidwe ntchito muukadaulo wafiriji.
Kuti athandizire kudziwa kuti malire atsopano a GWP adzakhala ati, othandizira a AIM Act adapempha kuti makampani apereke zopempha, zingapo zomwe EPA idaziganizira kale.EPA pakali pano ikugwira ntchito pazolemba zomwe akufuna kupanga malamulo, zomwe tikuyembekeza kuziwona chaka chino.
Njira ya EPA yochepetsera kufunika kwa HFC imagwiranso ntchito pakugwiritsa ntchito zida zomwe zilipo kale.Mbali yofunika iyi ya equation yofunikira imayang'ana kwambiri pakuchepetsa kutayikira, kutsimikizira, ndi kupereka malipoti (zofanana ndi lingaliro la EPA la Gawo 608, lomwe lidatsogolera mibadwo yam'mbuyomu ya magawo afiriji).EPA ikugwira ntchito kuti ipereke zambiri zokhudzana ndi kayendetsedwe ka HFC, zomwe zingapangitse kuti Gawo 608 libwezeretsedwe komanso/kapena pulogalamu yatsopano yobwezeretsanso HFC.

HFC PHASEDOWN Toolbox
Monga momwe Rajan adafotokozera mu webinar, gawo la HFC pamapeto pake likufuna kuchepetsa mpweya wowonjezera kutentha (GHG) potengera momwe amakhudzira chilengedwe.Kutulutsa kwachindunji kumatanthawuza kuthekera kwa mafiriji kutayikira kapena kutulutsidwa mumlengalenga;Kutulutsa kosalunjika kumatanthawuza kugwiritsa ntchito mphamvu zamagetsi zomwe zimagwirizanitsidwa ndi firiji kapena zida zoyatsira mpweya (zomwe zikuyerekezeredwa kuchulukitsa ka 10 kuchuluka kwa mpweya womwe umatulutsa mwachindunji).
Malinga ndi kuyerekezera kwa AHRI, 86% ya zonse zomwe zimagwiritsidwa ntchito mufiriji zimachokera ku firiji, zoziziritsira mpweya, ndi zida zopopera kutentha.Mwa izi, 40% yokha ingakhale chifukwa chodzaza zida zatsopano, pomwe 60% imagwiritsidwa ntchito powonjezera zida zomwe zakhala zikuchucha mwachindunji.
Rajan adagawana kuti kukonzekera kusintha kotsatira pakuchepetsa kwa HFC mu 2024 kudzafuna kuti makampani athu agwiritse ntchito njira zazikulu mubokosi lazida za HFC, monga kasamalidwe ka firiji ndi njira zabwino zopangira zida.M'machitidwe omwe alipo kale, izi zidzatanthauza kuwonjezereka kwa kuyang'ana pa kukonza kuti kuchepetsa kutayikira kwachindunji komanso kuwonongeka kwa chilengedwe cha kusayenda bwino kwadongosolo ndi mphamvu zamagetsi.Malangizo pamakina omwe alipo kale ndi awa:
 Kuzindikira, kuchepetsa, ndi kuthetsa kuchucha mufiriji;
Kubwezeretsanso mufiriji ya GWP yotsika m'kalasi lomwelo (A1), yokhala ndi mawonekedwe abwino kwambiri osankha zida zomwe zilinso zokonzeka A2L;ndi
Kupeza ndi kubwezeretsanso firiji kuti igwiritsidwe ntchito (osatulutsa mufiriji kapena kutulutsa mumlengalenga).
Pazida zatsopano, Rajan adalimbikitsa kugwiritsa ntchito njira yotsika kwambiri ya GWP ndikugwiritsa ntchito matekinoloje omwe akutuluka mufiriji omwe amawonjezera ndalama zochepa za firiji.Monga momwe zakhalira ndi njira zina zochepetsera zotsika - monga zodzipangira zokha, machitidwe a R-290 - cholinga chomaliza ndicho kukwaniritsa mphamvu zambiri zamakina pogwiritsa ntchito ndalama zochepa za firiji.
Pazida zonse zatsopano komanso zomwe zilipo, ndikofunikira kuti nthawi zonse muzisunga zida zonse, zida, ndi machitidwe molingana ndi momwe amapangidwira, kuphatikiza pakuyika, kutumiza ndi kugwira ntchito bwino.Kuchita izi kudzapititsa patsogolo mphamvu zamakina ndi magwiridwe antchito ndikuchepetsa zovuta zina.Pogwiritsa ntchito njirazi pazida zatsopano komanso zomwe zilipo kale, tikukhulupirira kuti makampani athu atha kukwaniritsa kuchepetsedwa kwa HFC pansi pa gawo la 2024 - komanso kuchepetsa 70% komwe kukukonzekera 2029.
KUSINTHA KWA A2L
Kukwaniritsa zofunikira zochepetsera za GWP kudzafunika kugwiritsa ntchito mafiriji a A2L omwe ali ndi "chiwopsezo chochepa".Njira zina izi - zomwe zikuyembekezekanso kukhala m'gulu la zomwe zivomerezedwe posachedwa ndi EPA - zakhala nkhani yakusintha mwachangu miyezo yachitetezo ndi malamulo omanga opangidwa kuti azitha kugwiritsidwa ntchito motetezeka mufiriji.Kuchokera kumalo osungiramo firiji, Rajan adalongosola kuti mafiriji a A2L akupangidwa bwanji komanso momwe amafananizira ndi omwe adawatsogolera a HFC malinga ndi GWP ndi kuchuluka kwa mphamvu.
