EPA irasaba ko ubucuruzi bwibiribwa bugomba gukoresha firigo ya R290 (izwi cyane nka hydrocarubone). Ubu buryo busanzwe, butekanye, kandi butari uburozi ntabwo bwangiza ibidukikije gusa ahubwo buhendutse. Ibi bivuze ko bitazagabanya gusa ibyuka bihumanya ikirere, ariko ubu buhanga bushya burashobora kandi kugabanya ikiguzi cyingufu zawe muri rusange kugera kuri 28%.

Ibikoresho bya firigo R290 bikoreshwa mubisanzwe mubucuruzi nkububiko bworoshye, supermarket, ninyubako zi biro. Ariko, zirakoreshwa kandi mubice bimwe byo guturamo. Impamvu yabyo iroroshye! Ibice bya firigo R290 bizigama amafaranga mugihe icyarimwe kurengera ibidukikije. Ibyo babikora bakoresheje hydrocarbone karemano aho gukoresha chlorofluorocarbone (CFCs). Izi firigo ziracyemerera urwego rumwe rwingufu zo gukonjesha, ariko ntizangiza ibyiciro bya ozone nibirekurwa mukirere. Ibi bituma baba inshuti zidasanzwe kuri iyi si yacu, niyo mpamvu ubucuruzi bugomba gutekereza guhinduranya moderi ya firigo R290.

Kuki firigo R290 ihitamo neza?

Firigo R290 nimwe mubindi bishya ku isoko kandi bifite inyungu nyinshi kurenza bagenzi bayo. Witegereze neza impamvu nke zituma ubu buryo bwiza buruta firigo ya I na II:

Ibidukikije

Firigo R290 ntabwo yangiza cyane ibidukikije. Niba irekuwe mu kirere, ntabwo bizagira uruhare mu kugabanuka kwa ozone kimwe nandi mahitamo. Icyatumye R290 isimburwa hafi yandi ma firigo nubushobozi bwayo bukabije bwubushyuhe bwisi (GWP) hamwe na zero ozone yo kugabanuka (ODP). Mu myaka mirongo, R134 na R404 nizo firigo zikoreshwa cyane mubucuruzi. Bombi bafite GWP idasanzwe cyane, bigatuma bagira uruhare runini mubushyuhe bwisi. Kurundi ruhande, firigo R290 ninshuti kubidukikije, bigatuma iba inzira nziza.

Ikiguzi

Tuba mw'isi aho kuramba ari ngombwa. Inganda zita ku biribwa zigomba rero kuba zifite inshingano zo kubungabunga ubuzima bw’ibidukikije. Firigo R290 nubundi buryo bwo gukemura inganda zitameze neza kwisi ariko kandi zizigama amafaranga. Ifite ubushobozi bwo kwinjiza ubushyuhe 90% kurusha abayibanjirije. Ibi bivuze gukira vuba mubushyuhe no gukoresha ingufu nke. Uzazigama amafaranga mugihe ufite amahoro yo mumutima uzi ko udatanga umusanzu mubushyuhe bwisi.

Guhuza

Kimwe mubintu byatumye firigo ya R290 ikundwa cyane nubushobozi bwayo bwo gushyirwa mubintu byinshi bishaje bitabaye ngombwa ko uhindura sisitemu zose. Ibi bivuze ko igihe gito n'amafaranga bikoreshwa mugihe bikwemerera gukomeza kungukirwa nikoranabuhanga ryiza. Byongeye kandi, firigo R290 zirahinduka kuburyo budasanzwe, kandi zirashobora gukoreshwa mugukoresha ingufu za firigo yubucuruzi muri resitora, aho barira, hamwe namakamyo y'ibiryo. Hamwe n'ibimaze kuvugwa, biragaragara impamvu ubucuruzi bugomba gukora switch hanyuma igatangira gukoresha moderi ya firigo R290.

Irashobora guhumeka mu kirere.

Kimwe mu byiza byingenzi bya R290 ni uko gishobora guhita cyinjira mu kirere bitabaye ngombwa ko gifatwa kandi kigakoreshwa. Ibi bivanaho abatekinisiye bitwaje tanki ihenze hamwe nibindi bikoresho byari bisanzwe bikoreshwa mugihe bakorera sisitemu ishaje ukoresheje 134 cyangwa 404. Kubera iyo mpamvu, iyi ni serivisi icungwa neza kuri bo kandi uzishyura make cyane ugereranije nibyo wasangaga wishyura kugirango ubungabunge kandi serivisi.

Gusubiramo

R290 ifite kandi ibimenyetso byerekana ko byoroshye gukoreshwa, kuyikoresha kubindi bikorwa. Iyi ninkuru nziza kubashaka kuzigama amafaranga no gukoresha ubundi buryo bwafatwa nkimyanda.

Kuramba

R290 nayo igiye kuba igipimo gishya cyibikoresho bizakorwa mugihe kizaza. Ibi bivuze ko utazigera uhangayikishwa no kuzamura ibiciro bihenze no kubisimbuza igihe ibipimo bishya bimaze gusohoka no gushyirwa mubikorwa. Iragufasha gutera intambwe imwe igana icyatsi ejo.

Umwanzuro

R290 ni firigo iramba kandi birashoboka ko ari amahitamo yawe mugihe cyo kugura firigo yubucuruzi kubucuruzi bwawe. R290 ni firigo izatuma ibice byawe bimara igihe kirekire kandi bifite ibyangombwa byiza byibidukikije.
