Biri hafi kubona abasimbuza firigo ya kabiri na gatatu!
Ku ya 15 Nzeri 2021, "Ivugurura rya Kigali kuri Protokole ya Montreal ku bintu byangiza Ozone Layeri" ryatangiye gukurikizwa mu Bushinwa.Nk’uko "Montreal Protocol" ibivuga, firigo yo mu gisekuru cya kabiri HCFC izahagarika gukoreshwa mu 2030. Iri vugurura risaba ko mu 2050, ikoreshwa rya HFCs ku isi rizagabanuka hafi 85%.
Iki nikintu cyibanze mubikorwa bya firigo, kandi binatanga ikimenyetso kinini cya politiki cyerekana ko amahanga yiyemeje guhagarika ikoreshwa rya HFC.
Muri icyo gihe, hamwe no gushyiraho intego yo mu rugo "dual-carbone" no gushyira mu bikorwa buhoro buhoro politiki yo kugenzura firigo yo mu gisekuru cya gatatu HFCs, birihutirwa kwiga HCFC, insimburangingo ya HFC hamwe n’ikoranabuhanga bijyanye.
Firigo yinjira mugihe cyigiciro gito cya GWP, kandi ikibazo cyo gutwikwa ntigishobora kwirengagizwa!
Muri rusange, gukoresha firigo yaka umuriro hamwe na GWP nkeya kugirango usimbuze HCFC nizindi myuka irimo fluor bifatwa nkigisubizo cyiza kandi gito.Nyamara, ubushakashatsi bwerekanye ko firigo gakondo zidakunze kuzuza ibisabwa byose bya firigo zizaza kuri GWP nkeya, umutekano, imikorere ya termodinamike hamwe nibidukikije icyarimwe.
Muyandi magambo, indangagaciro nyinshi za GWP zirashya!
Igipimo cyigihugu "Uburyo bwa Numero ya Firigo no Gutondekanya Umutekano" GB / T 7778-2017 igabanya uburozi bwa firigo mu cyiciro cya A (uburozi buke bwa karande) na B B (uburozi bukabije bwa karande), kandi gutwika byashyizwe mu cyiciro cya 1 (Nta gukwirakwiza umuriro) ), Icyiciro cya 2L (birashoboka cyane), Icyiciro cya 2 (birashoboka), nicyiciro cya 3 (cyaka kandi giturika).Ukurikije GB / T 7778-2017, umutekano wa firigo ugabanijwemo ibyiciro 8, aribyo: A1, A2L, A2, A3, B1, B2L, B2, na B3.Muri byo, A1 niyo ifite umutekano na B3 ni mbi cyane.
Nigute ushobora gukoresha firigo ya A2L HFO neza kandi neza?
Nubwo ibyuma bifata ibyuma bikonjesha murugo, ibyuma bikonjesha hamwe nibindi bikoresho bya firigo byageragejwe kugirango bikore muruganda, hagaragazwa agaciro kerekana amafaranga ya firigo.Nyamara, ibice byinshi binini bikonjesha hamwe na chillers yinganda bigomba kuzuzwa na firigo aho bikorerwa, kimwe nubuhumekero bwo murugo, ibikoresho bya firigo, kubika imbeho, nibindi mugihe cyo kubungabunga.
Byongeye kandi, kubera ubwoko butandukanye bwimyuka ikoreshwa mubikoresho bimwe, amafaranga ya firigo aratandukanye.Usibye kubungabunga no gushiraho, kubera imiterere mike, abakozi benshi babungabunga bishyuza firigo ukurikije uburambe.Byongeye kandi, inganda nazo zumva cyane ikibazo cya firigo.
Hashingiwe kuri ibi, Chemours yatangije R1234yf, R454A, R454B, R454C nizindi A2L zidakongoka cyane, firigo za GWP nkeya, kandi yiyemeje guteza imbere igishushanyo mbonera cya sisitemu n’amahugurwa azwi cyane kugirango akemure ingaruka ziterwa n’umuriro.
Urwego rwumutekano A2L rufite ibiranga uburozi buke (A) hamwe no gucana intege nke (2L).Firigo nyinshi za A2L HFO zifite imikorere ihanitse kandi iranga GWP nkeya, kandi ni byiza gusimbuza ibisekuruza byabanjirije firigo ya HFC.Ibicuruzwa bya A2L ntibikoreshwa cyane ku isoko mpuzamahanga, ariko amasosiyete menshi yo mu gihugu nayo yihutishije umuvuduko wo kuzamura no kwinjiza ubu bwoko bushya bwa firigo mubikorwa byo gukora.Kurugero, Johnson Igenzura ikoresha Oteon ™ XL41 (R-454B) muri York ® YLAA ya chiller ya chiller kumasoko yuburayi;Umwikorezi ahitamo kandi R-454B (iyo niyo Nkuru yingenzi ya firigo ya GWP, Carrier izakoresha R-454B mumiturirwa yayo ituje kandi yoroheje ya HVAC igurishwa muri Amerika ya ruguru kuva 2023. Simbuza R-410A.
