Biri hafi kubona abasimbuza firigo ya kabiri na gatatu!
Ku ya 15 Nzeri 2021, "Ivugurura rya Kigali ku masezerano ya Montreal ku bintu byangiza urwego rwa Ozone" 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, isi yose HFCs izagabanuka ku kigero cya 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 ya "dual-carbone" yo mu gihugu no gushyira mu bikorwa buhoro buhoro politiki yo kugenzura firigo ya gatatu ya firigo ya HFCs, byihutirwa kwiga HCFC, HFCs isimbuza ibintu hamwe n’ikoranabuhanga bijyanye.
Firigo yinjira mugihe cyigiciro gito cya GWP, kandi ikibazo cyokongoka ntigishobora kwirengagizwa!
Muri rusange, gukoresha firigo yaka umuriro ifite agaciro ka GWP kugirango isimbuze HCFC nizindi myuka irimo fluor ifatwa nkigisubizo cyiza kandi gito. Nyamara, ubushakashatsi bwerekanye ko firigo gakondo zidakunze kuzuza ibisabwa byose bya firigo zizaza kuri GWP nkeya, umutekano, imikorere ya termodinamike nibikorwa byibidukikije icyarimwe.
Muyandi magambo, indangagaciro nyinshi za GWP zirashya!
Igipimo cy’igihugu "Uburyo bwa Numero ya Firigo no Gutondekanya Umutekano" GB / T 7778-2017 igabanya uburozi bwa firigo mu cyiciro cya A (uburozi buke budakira) na B B (uburozi bukabije bwa karande), kandi gutwika byashyizwe mu cyiciro cya 1 (Nta gukwirakwiza umuriro), Icyiciro cya 2L (birashoboka), Icyiciro cya 2 (birashoboka), n’icyiciro cya 3 (cyaka). Dukurikije 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 mumutekano kandi neza?
Nubwo ibyuma bifata ibyuma bikonjesha murugo, ibyuma bikonjesha hamwe nibindi bikoresho bya firigo byageragejwe kugirango bikore ku ruganda, hagaragazwa agaciro kerekana amafaranga ya firigo. Nyamara, ibice byinshi binini bikonjesha ikirere hamwe na chillers yinganda bigomba kuzuzwa firigo aho, kimwe nubuhumekero bwo murugo, ibikoresho bya firigo, ububiko bukonje, 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 bashinzwe kubungabunga bishyuza firigo ukurikije uburambe. Byongeye kandi, inganda nazo zumva cyane ikibazo cyo gutwika firigo.
Hashingiwe kuri ibi, Chemours yatangije R1234yf, R454A, R454B, R454C nizindi A2L zidakongoka cyane, firigo nkeya za GWP, kandi yiyemeje guteza imbere igishushanyo mbonera cya sisitemu n’amahugurwa azwi cyane mu gukemura ibibazo by’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 insimburangingo nziza kubisekuru 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 bwa firigo mu bikorwa. Kurugero, Johnson Igenzura ikoresha Oteon ™ XL41 (R-454B) muri York ® YLAA imizingo ya chiller kumasoko yuburayi; Umwikorezi ahitamo kandi R-454B (niyo Nka firigo nyamukuru ya GWP yo hasi, Carrier izakoresha R-454B mububiko bwayo butuye kandi bworoshye ibicuruzwa bya HVAC bigurishwa muri Amerika ya ruguru kuva 2023. Simbuza R-410A.
