Amabwiriza ya firigo akomeje kwihindagurika

Emerson webinar yatanze ivugurura kubipimo bishya bijyanye no gukoresha A2Ls

Mugihe twegereje igice cyumwaka, inganda za HVACR zirimo gukurikiranira hafi mugihe intambwe ikurikiraho kwisi yose ya firigo ya hydrofluorocarbon (HFC) igaragara kuri horizone.Intego zigaragara za decarbonisation zitera kugabanuka mukoresha imikoreshereze ya GWP HFCs hamwe ninzibacyuho izakurikiraho, ubundi-firigo ya GWP.
Muri Webinar ya E360 iherutse, Rajan Rajendran, visi perezida wa Emerson ku isi ku buryo burambye, kandi natanze amakuru ajyanye n’imiterere y’amabwiriza ya firigo n'ingaruka zayo ku nganda zacu.Kuva muri federasiyo na leta iyobowe na gahunda zicyiciro cya mbere kugeza ku iterambere ry’umutekano rigenga ikoreshwa rya firigo ya A2L “flammability yo hasi”, twatanze incamake y’imiterere iriho ubu tunaganira ku ngamba zo kugera ku kugabanuka kwa HFC na GWP.

AIM ACT
Ahari umushoferi w'ingenzi muri Amerika HFC icyiciro cya kabiri ni itegeko ryo muri 2020 ryemejwe itegeko ryo guhanga udushya no gukora inganda muri Amerika (AIM) hamwe nububasha biha ikigo gishinzwe kurengera ibidukikije (EPA).EPA irimo gushyiraho ingamba zigabanya itangwa n’ibisabwa bya GWP HFC nyinshi kuri gahunda yicyiciro cyagenwe n’ivugururwa rya Kigali kuri Protokole ya Montreal.
Intambwe yambere yatangiye uyumwaka igabanutseho 10% mugukoresha no gutanga umusaruro wa HFCs.Intambwe ikurikiraho izagabanywa 40%, izatangira gukurikizwa mu 2024 - igipimo cyerekana intambwe ya mbere ikomeye yagaragaye mu mirenge ya HVACR yo muri Amerika.Umusaruro wa firigo hamwe nu bicuruzwa byatumijwe mu mahanga bishingiye ku gipimo cya GWP cya firigo yihariye, bityo bigashyigikira kongera umusaruro wa firigo nkeya-GWP no kugabanuka kuboneka kwa HFCs nyinshi.Kubwibyo, amategeko yo gutanga no gusaba azamura ibiciro bya HFC kandi byihutishe inzibacyuho yo hasi-GWP.Nkuko twabibonye, ​​inganda zacu zimaze guhura nibiciro bya HFC.
Ku ruhande rusabwa, EPA irasaba kugabanya imikoreshereze ya GWP HFC mu bikoresho bishya ishyiraho imipaka mishya ya firigo ya GWP mu gukonjesha ubucuruzi no gusaba guhumeka.Ibi birashobora kuganisha ku kugarura politiki yingenzi yubundi buryo bushya (SNAP) amategeko 20 na 21 na / cyangwa gutangiza ibyifuzo bya SNAP bigamije kwemeza amahitamo mashya ya GWP mugihe azaboneka kugirango akoreshwe muburyo bwa tekinoroji yo gukonjesha.
Kugirango dufashe kumenya imipaka ntarengwa ya GWP izaba, abaterankunga ba AIM Act basabye ko hajyaho inganda binyuze mubisabwa, inyinshi muri zo EPA imaze kuzirikana.Muri iki gihe EPA irimo gukora imishinga yo gufata ibyemezo, twizera ko tuzabona uyu mwaka.
Ingamba za EPA zo kugabanya ibyifuzo bya HFC zirakoreshwa no gutanga ibikoresho bihari.Iyi ngingo yingenzi yo kugereranya ibyifuzo byibanda cyane cyane kugabanya kugabanuka, kugenzura, no gutanga raporo (bisa nicyifuzo cya EPA cyo mu gice cya 608, cyayoboye ibisekuruza byabanjirije firigo).EPA irimo gukora kugirango itange ibisobanuro birambuye bijyanye nubuyobozi bwa HFC, bishobora kuvamo kugarura igice cya 608 na / cyangwa gahunda nshya yo gutangiza HFC.

HFC YAKORESHEJWE
Nkuko Rajan yabisobanuye kurubuga, HFC icyiciro cya nyuma igamije kugabanya ibyuka bihumanya ikirere (GHG) hashingiwe ku ngaruka zabyo zitaziguye kandi zitaziguye ku bidukikije.Ibyuka bihumanya bitaziguye bivuga ubushobozi bwa firigo kumeneka cyangwa kurekurwa mukirere;ibyuka bitaziguye bivuga gukoresha ingufu za firigo cyangwa ibikoresho bifata ibyuma bikonjesha (bivugwa ko bikubye inshuro 10 ingaruka ziterwa n’ibyuka bihumanya ikirere).
Ugereranyije na AHRI, 86% ya firigo zose zikoreshwa zikomoka kuri firigo, ubukonje, nibikoresho bya pompe.Muri ibyo, 40% gusa ni byo bishobora kwitirirwa kuzuza ibikoresho bishya, mu gihe 60% bikoreshwa mu kuzimya sisitemu zagiye ziva muri firigo.
Rajan yavuze ko kwitegura guhindura intambwe ikurikiraho mu kugabanya HFC mu 2024 bizasaba inganda zacu gukoresha ingamba zingenzi mu isanduku y’ibikoresho bya HFC, nko gucunga firigo ndetse no gutegura ibikoresho uburyo bwiza.Muri sisitemu zisanzweho, ibi bizasobanura ko hibandwa cyane ku kubungabunga kugira ngo bigabanye gutemba bitaziguye ndetse n’ingaruka zitaziguye ku bidukikije ku mikorere mibi ya sisitemu no gukoresha ingufu.Ibyifuzo bya sisitemu zisanzwe zirimo:
Kumenya, kugabanya, no gukuraho firigo;
Guhindura firigo yo hasi-GWP murwego rumwe (A1), hamwe nibintu byiza cyane byo guhitamo ibikoresho nabyo A2L-byiteguye;na
Kugarura no kugarura firigo kugirango ikoreshwe muri serivisi (ntuzigere ushiramo firigo cyangwa ngo urekure mu kirere).
Kubikoresho bishya, Rajan yasabye ko hakoreshwa ubundi buryo bushoboka bwa GWP no gukoresha tekinoroji ya firigo ikonjesha ikoresha amafaranga make ya firigo.Nkuko byagenze kubandi mahitamo make-yishyurwa - nka wenyine, sisitemu R-290 - intego yanyuma ni ukugera kubushobozi bwa sisitemu ntarengwa ukoresheje amafaranga make ya firigo.
Kubikoresho byombi nibisanzweho, nibyingenzi guhora kubungabunga ibice byose, ibikoresho, na sisitemu ukurikije uburyo bwiza bwo gushushanya, harimo mugihe cyo kwishyiriraho, gutangiza no gukora bisanzwe.Kubikora bizamura imikorere yingufu za sisitemu no gukora mugihe hagabanijwe ingaruka zitaziguye.Mugushira mubikorwa izi ngamba kubikoresho bishya kandi bihari, twizera ko inganda zacu zishobora kugera kuri HFC kugabanuka munsi ya 2024 - ndetse no kugabanya 70% biteganijwe muri 2029.
A2L BYIHUTIRWA
Kugera kuri GWP ikenewe bizakenera gukoresha firigo za A2L zigaragara hamwe nu rutonde rwa "flammability yo hasi".Izi nzira zindi - nazo zishobora kuba mubishobora kwemezwa na EPA - zagiye zishyirwaho amahame yumutekano yihuta cyane hamwe n’amategeko agenga imyubakire yagenewe gukoreshwa neza muri firigo yubucuruzi.Urebye ahantu nyaburanga hakonjeshwa, Rajan yasobanuye firigo ya A2L irimo gutezwa imbere nuburyo bagereranya nabababanjirije HFC mubijyanye na GWP hamwe nubushobozi bwabo.
