R1234yf nimwe muma firigo nziza ya R134a. Kugirango twige imikorere ya firigo nubushyuhe bwa sisitemu ya R1234yf,ibinyabiziga bishya byingufu pompe yumuyagaintebe yubushakashatsi yarubatswe, kandi itandukaniro mubikorwa byo gukonjesha no gushyushya hagati ya sisitemu ya R1234yf na sisitemu ya R134a byagereranijwe hakoreshejwe ubushakashatsi. Ibisubizo byubushakashatsi byerekana ko ubushobozi bwo gukonjesha na COP ya sisitemu ya R1234yf iri munsi yubwa R134a. Mugihe cyo gushyushya, ubushyuhe bwa sisitemu ya R1234yf isa nubwa R134a, naho COP iri munsi ya R134a. Sisitemu ya R1234yf irafasha cyane gukora neza kubera ubushyuhe bwayo buke.
R134a ifite ubushyuhe bukabije ku isi (GWP) yo mu 1430, ikaba ari GWP isumba izindi muri firigo zikunze gukoreshwa. Ubwiyongere bw'abantu bangiza ibidukikije, ikoreshwa rya firigo nyinshi za GWP ryatangiye kugabanuka. Firigo nshya R1234yf, kubera GWP yayo 4 gusa na ODP ya 0, ifite imiterere yumuriro isa na R134a kandi biteganijwe ko izahinduka imwe muri firigo nziza kuri R134a.
Muri ubu bushakashatsi bwubushakashatsi, R1234yf isimburwa mu buryo butaziguye muri R134asisitemu nshya yubushyuhe pompe sisitemu yo guhumeka intebe yikizamini, kandi itandukaniro ryimikorere hagati ya sisitemu ya R1234yf na sisitemu ya R134a muburyo butandukanye bwo gukonjesha hamwe nubushyuhe bwa pompe. Hafashwe imyanzuro ikurikira.
1) Mugihe cyo gukonjesha, ubushobozi bwo gukonjesha na COP ya sisitemu ya R1234yf biri munsi yubwa sisitemu ya R134a, kandi icyuho cya COP kigenda cyiyongera buhoro buhoro hamwe no kwiyongera kwihuta. Ugereranije no guhererekanya ubushyuhe muri kondenseri hamwe nubushobozi bwo gukonjesha muri moteri, umuvuduko mwinshi wa sisitemu ya R1234yf yishyura ubushyuhe bwayo bwihishwa bwuka.
2) Mugihe cyubushyuhe, umusaruro wubushyuhe bwa sisitemu ya R1234yf uhwanye nubwa sisitemu ya R134a, kandi COP iri munsi yubwa R134a, kandi umuvuduko mwinshi hamwe nogukoresha ingufu za compressor nimpamvu zitaziguye zo hasi COP. Mugihe cy'ubushyuhe buke, bitewe no kwiyongera k'ubunini bwihariye bwo guhumeka no kugabanuka kw'imigezi myinshi, kongera ubushyuhe bwa sisitemu zombi birakomeye.
3) Mugihe cyo gukonjesha no gushyushya, ubushyuhe bwa R1234yf buri munsi yubwa sisitemu ya R134a, ifashaimikorere ihamye ya sisitemu.
