Emerson webinar akapa gadziriso pamazinga matsva maererano nekushandiswa kweA2Ls
Sezvo tave pedyo nepakati pepakati pegore, indasitiri yeHVACR iri kutarisisa sezvo matanho anotevera muchikamu chepasi rose chehydrofluorocarbon (HFC) mafiriji achionekwa kumberi.Zvinangwa zviri kubuda zve decarbonization zviri kutyaira kudzikiswa kwekushandiswa kwepamusoro-GWP HFCs uye shanduko kuenda kuchizvarwa chinotevera, yakaderera-GWP mafiriji dzimwe nzira.
Mune ichangoburwa E360 Webinar, Rajan Rajendran, mutevedzeri wemutungamiri wepasi rose weEmerson wekusimudzira, uye ini ndakapa gadziriso pamamiriro emitemo yefiriji uye maitiro ayo paindasitiri yedu.Kubva pahurongwa hwemubatanidzwa uye hunotungamirwa nehurumende kusvika pakuvandudza mitemo yedziviriro inodzora kushandiswa kwemafiriji eA2L “akaderera kupisa”, takapa muchidimbu mamiriro azvino uye takakurukura nzira dzekuwana kudzikiswa kwazvino uye kweramangwana HFC neGWP.
AIM ACT
Zvichida mutyairi akanyanya kukosha muUS HFC kudzika kwaive kupasa kwa2020 kweAmerican Innovation and Manufacturing (AIM) Act uye nemvumo yainopa kune Environmental Protection Agency (EPA).EPA iri kudzika zano rinoganhura kupihwa uye kudiwa kwepamusoro-GWP HFCs padanho rekudzika rakatarwa neKigali Amendment kuMontreal Protocol.
Danho rekutanga rakatanga gore rino nekudzikiswa kwe10% mukushandiswa nekugadzirwa kweHFCs.Nhanho inotevera ichave kudzikiswa ne40%, ichatanga muna 2024 - bhenji rinomiririra kudzika kukuru kwekutanga kunzwika mukati meUS HVACR zvikamu.Refrigerant production and import quotas inobva paGWP rating yeimwe firiji, nokudaro zvichitsigira kuwedzera kwekugadzirwa kwepasi-GWP refrigerants uye kuderera kwekuwanika kwepamusoro-GWP HFCs.Nekudaro, mutemo wekupa uye kudiwa uchakwidza mitengo yeHFC uye nekumhanyisa shanduko kune yakaderera-GWP sarudzo.Sezvataona, indasitiri yedu yave kutoona kukwira kwemitengo yeHFC.
Padivi rekuda, EPA iri kuronga kutyaira pasi yakakwira-GWP HFC kushandiswa mumidziyo mitsva nekuisa miganho mitsva yeGWP yefiriji mufiriji yekutengesa uye maapplication emhepo.Izvi zvinogona kutungamira kudzoreredzwa kweYakakosha New Alternatives Policy (SNAP) mitemo yechi20 uye 21 uye/kana kuunzwa kweSNAP zvikumbiro zvine chinangwa chekubvumidza mitsva yakaderera-GWP sarudzo sezvadzinove dziripo kuti dzishandiswe muchiri kubuda matekinoroji efiriji.
Kubatsira kuona kuti miganho mitsva yeGWP ichave yei, vatsigiri veAIM Act vakakumbira kuiswa kweindasitiri kuburikidza nezvikumbiro, zvakati wandei izvo EPA yakatofunga nezvayo.Parizvino EPA iri kushanda pagwaro remitemo yakarongwa, yatinotarisira kuona gore rino.
Iyo EPA zano rekudzikamisa kudiwa kweHFC rinoshandawo pasevhisi yemidziyo iripo.Ichi chakakosha cheiyo equation yekuda yakatarisana nekudzikisira kuvuza, kusimbiswa, uye kushuma (zvakafanana neEPA's Chikamu 608 chikumbiro, icho chaitungamira zvizvarwa zvakapfuura zvefiriji phasedowns).EPA iri kushanda kuti ipe ruzivo rwakanangana nehutungamiriri hweHFC, izvo zvinogona kukonzera kudzoreredzwa kweChikamu 608 uye/kana chirongwa chitsva cheHFC.
HFC PHASEDOWN TOOLBOX
Sezvakatsanangurwa naRajan muwebinar, iyo HFC phasedown pakupedzisira yakanangana nekudzikisa greenhouse gasi (GHG) kuburitswa zvichienderana nekukanganisa kwavo kwakananga uye kusiri kwakananga kwezvakatipoteredza.Direct emissions inoreva mukana wekuti mafiriji adonhe kana kuburitswa mumhepo;indirect emissions inoreva kushandiswa kwesimba kweinosanganisirwa firiji kana mhepo yekumisikidza midziyo (iyo inofungidzirwa kuva kanokwana ka10 kukanganisa kwekubuda kwakananga).
Pakufungidzira kubva kuAHRI, 86% yezvese kushandiswa kwefiriji kunobva mufiriji, mhepo inofefetera, uye pombi yekupisa.Pane izvo, makumi mana muzana chete anogona kuverengerwa kuzadza midziyo mitsva, nepo makumi matanhatu muzana anoshandiswa kudonhedza masisitimu anga aine kudonha kwefiriji.
Rajan akagovera kuti kugadzirira danho rinotevera mukuderedzwa kweHFC muna 2024 kunoda kuti indasitiri yedu iwedzere nzira dzakakosha muHFC phasedown toolbox, senge firiji manejimendi uye dhizaini dhizaini maitiro akanakisa.Mune masisitimu aripo, izvi zvinoreva kuwedzera kutarisisa kwekugadzirisa kudzikisa kudonhedza kwakananga uye kusakonzeresa kwezvakatipoteredza kukanganiswa kwekuita kwakashata kwehurongwa uye kugona kwesimba.Zvinokurudzirwa kune aripo masisitimu anosanganisira:
Kuona, kudzikisira, nekubvisa zvinobuda mufiriji;
Kudzoreredza kune yakaderera-GWP refrigerant mukirasi imwechete (A1), ine yakanakisa-kesi mamiriro ekusarudza michina iyo zvakare A2L-yakagadzirira;uye
Kudzoreredza uye kudzoreredza refrigerant kuti ishandiswe musevhisi (usambofa wakaburitsa mufiriji kana kuburitswa mumhepo).
Zvemidziyo mitsva, Rajan akakurudzira kushandisa yakaderera inogoneka GWP imwe nzira uye kutora ari kubuda mafiriji system matekinoroji anokwirisa akaderera machaji efiriji.Sezvakave zvakaita kune dzimwe sarudzo dzepasi-muchaji - senge-yega, R-290 masisitimu - chinangwa chekupedzisira ndechekuwana yakanyanya system kugona uchishandisa hushoma huwandu hwefiriji charge.
Kune ese ari maviri emidziyo mitsva uye iripo, zvakakosha kuti ugare uchichengetedza zvese zvikamu, zvishandiso, uye masisitimu zvinoenderana neyakakwana dhizaini mamiriro, kusanganisira panguva yekuisa, yekumisikidza uye yakajairika kushanda.Kuita izvi kunovandudza sisitimu simba rekuita uye kuita uku uchideredza zvisina kunanga kukanganisa.Nekushandisa mazano aya pamidziyo mitsva uye iripo, tinotenda kuti indasitiri yedu inogona kuwana kudzikiswa kweHFC pazasi pechikamu cha2024 - pamwe nekudzikiswa kwe70% kwakarongerwa 2029.
A2L KUSVIRA
Kuzadzikisa kudiwa kweGWP kunoda kushandiswa kwemafiriji eA2L ari kubuda ane "yakaderera kupisa" rating.Idzi dzimwe nzira - zvakare dzinogona kunge dziri pakati peidzo dzichakurumidza kubvumidzwa neEPA - dzanga dziri nyaya yekukurumidza kushanduka kwemaitiro ekuchengetedza uye macode ekuvaka akagadzirirwa kugonesa kushandiswa kwakachengeteka mufiriji yekutengesa.Kubva pane firiji nzvimbo yekutarisa, Rajan akatsanangura kuti ndeapi mafiriji eA2L ari kugadzirwa uye kuti anoenzanisa sei nevanotangira HFC maererano neGWP uye huwandu hwehuwandu.
