Umutanga Firigo Igendanwa: 2-8C Konjesha Ifite Bateri Ihoraho Amasaha 48 yo Gutanga Inkingo mu Kilometero cya Nyuma

Buri mwaka, hafi 50% by'ibura ry'inkingo mu bihugu bikiri mu nzira y'amajyambere biterwa n'ibura ry'inkingo zikonjesha—si inenge zo mu nganda, ahubwo ni ukunanirwa kw'ubwikorezi, ububiko, no gutanga inkingo mu buryo bwa nyuma. Ingaruka si iz'ibanga. Iyo umukozi ushinzwe ubuzima mu karere ko mu cyaro cya Zambiya afunguye firigo agasanga ubushyuhe bwatumye doze 200 z'inkingo zidashobora kubaho, ikiguzi nyacyo gipimwa ku bana badakingiwe. Iyi nyandiko ni iy'imiryango igura firigo zigendanwa—kandi ikubiyemo ibijyanye na tekiniki, amategeko, n'imikorere bigena niba izo nkingo zizakomeza kubaho.

Ikibazo cy'umuvuduko w'ubukonje: Impamvu gutanga serivisi mu buryo bwa nyuma bitandukanye

Gutanga ibikoresho bisanzwe byo gukonjesha bikurikiza ihame ryoroshye: gushaka icyuma cyujuje ubushyuhe, kugenzura icyemezo, no guteganya igiciro. Iyo shingiro irasobanura uburyo bwo gutanga urukingo rwa nyuma kuko imiterere yacyo itandukanye cyane n'ikintu icyo ari cyo cyose firigo isanzwe ihura nacyo. Ihame rya nyuma rigaragazwa n'ingufu zitizewe, ubushyuhe bwinshi, ubwikorezi bubi bwo mu muhanda, n'ibikorwaremezo bike by'ubufasha mu bya tekiniki. Frigo ikora neza mu ivuriro ry'umujyi mukuru rifite amashanyarazi yizewe izapfa burundu mu kigo nderabuzima cy'akarere mu cyaro cya Nijeri aho amashanyarazi aboneka amasaha 8 ku munsi.

Kubera izi mpamvu, twakoze firigo yacu igendanwa ikoreshwa mu buryo bwihariye ku bantu badashobora gukoresha cyane cyane. Twabyize mu buryo bugoye—ubwoko bwa mbere bw’ibyo twitaga udusanduku dukonje dufite compressors bwaranzwe mu igeragezwa ryo mu murima kuko batashoboraga kubungabunga ubushyuhe mu gihe cy’amasaha 36 yo guhagarika ingufu mu bushyuhe bwa dogere selisiyusi 40. Twamaze imyaka ibiri tuvugurura sisitemu yo gukingira no gucunga bateri mbere yo kubona urutonde rwa mbere rwa OMS Prequalification mu 2022. Iyo niyo mpamvu twanditse iyi nyandiko: icyuho kiri hagati ya firigo y’ubucuruzi na firigo iteguye gukingira mu murima ni kinini, kandi amakosa yo kugura hafi ya yose arahenze kandi rimwe na rimwe akaba ari menshi cyane.

Ibisabwa mu bushyuhe: Igipimo cya 2-8C n'impamvu guhagarara ari ingenzi kuruta uburebure

Umuryango Mpuzamahanga wita ku Buzima washyizeho ahantu habiri hatandukanye ho kubika inkingo, kandi gusobanukirwa itandukaniro ni ibintu bidashoboka kugira ngo haboneke inkingo. Ububiko busanzwe bw'inkingo (2-8C) irakenewe ku nkingo nyinshi z’abana zirimo poliyo, iseru, diphtheria-tetanus-pertussis (DTaP), hepatite B, na fever y’umuhondo. Izi ni inkingo zidakora zigabanuka vuba iyo zikonje cyangwa zihuye n’ubushyuhe buri hejuru ya 8C. Ubushyuhe bwo hejuru bwa 8C si intego y’umwimerere—ni igipimo gikomeye. Kurenza 8C mu gihe icyo ari cyo cyose gihoraho bitera kwangirika kwa poroteyine mu buryo budasubirwaho muri izi nkingo. Urukingo rushobora kwangirika mu gukonjesha (-15C kugeza -25C) birakenewe ku miti imwe n'imwe ya meningite A (MenAfriVac), inkingo zirimo meningite mu ducupa twinshi, hamwe n'izindi nkingo nshya. Izi ntizigomba na rimwe gushyirwa mu bushyuhe buri hejuru ya -15C, bivuze ko uburyo bwo kurinda ubukonje no kugenzura ubushyuhe ari ngombwa.

Ingingo y'ingenzi abaguzi benshi batabona: Ibisobanuro bya OMS ntabwo ari ibijyanye n'ubushyuhe gusa—ni ibyerekeye ubushyuhe buhamye uko igihe kigenda gihita. Igice gikomeza ubushyuhe bwa 2-8C mu gihe gisanzwe ariko kikagera kuri 10C mu gihe cy'ingufu zihagarara cyangwa kuri 0C mu gihe cy'ubukonje bukabije ntikiba gikwiye. Kubera ko inkingo ari ibintu bikomoka ku binyabuzima, igipimo cy'ingenzi ni igihe mu gace k'akaga—igihe ubushyuhe bwari buri hanze y'urwego rwemewe, ntabwo ari uko byari bimeze gusa mu kanya gato. Porogaramu yo gupima WHO EUL/Prequalification yigana ibi binyuze mu gukoresha igikoresho mu gihe cy'iminsi 5 cy'ubushyuhe burimo kunanirwa kw'amashanyarazi, guhinduka k'ubushyuhe kuva kuri 15C kugeza kuri 43C, hamwe n'inshuro zo gufungura imiryango zisubiramo ikoreshwa mu buvuzi nyabwo. Ibice bitsinda iyi porogaramu bishyirwa ku rutonde rwa WHO Prequalification Database kandi bujuje ibisabwa kugira ngo bihabwe UNICEF na Gavi. Turasaba cyane kugura gusa ku bacuruzi bafite ibipimo bigaragara ku rutonde rwa WHO Prequalification, ruvugururwa buri gihembwe kandi ruboneka ku rubuga rwa WHO.

Bateri yo kubika amakuru amasaha 48: Uburyo budasubirwaho bwo gukoresha inzira za nyuma

Niba ubushyuhe budahindagurika ari cyo kintu cy'ingenzi gisabwa, bateri y'amasaha 48 ni yo ituma ubushyuhe bushoboka mu kazi. Mu bunararibonye bwacu, uburyo amashanyarazi akoreshwa mu turere twibandwaho mu gutanga urukingo mu buryo bwa nyuma bumeze gutya: Afurika yo munsi y'ubutayu bwa Sahara (uturere tw'icyaro): Impuzandengo y’ubukode bw’amashanyarazi ni 70-85%, aho kubura ingufu bikunze kumara amasaha 12-48. Muri Afurika y’Iburengerazuba, guhindagurika kwa harmonic no kugabanuka k’amashanyarazi mu gihe cy’ihindagurika ry’amashanyarazi birakomeye bihagije ku buryo byangiza compressors ku bikoresho bidafite amashanyarazi yubatswemo. Aziya y'Amajyepfo y'Uburasirazuba (intara za kure): Igihe cy'imvura kigera ku gihe cy'amasaha 4-8 ku munsi. Ibigo nderabuzima byo mu cyaro muri Miyanimari, Lawosi na Kamboje bivuga ko amashanyarazi ahagarara inshuro 20-30 buri kwezi mu gihe cy'imvura. Amerika y'Epfo (uturere twa Andean na Amazon): Ubuziranenge bw'imiyoboro y'amashanyarazi mu byaro bya Peru, Boliviya na Ekwateri buri hagati ya 75-80%, aho abaturage bo mu byaro bahura n'ikibazo cyo kubura ingufu mu minsi myinshi mu gihe cy'ibiza n'ibikorwaremezo byangiritse.

Bateri y'inyongera y'amasaha 48 ikemura ibi bibazo byose. Iyo umuriro w'amashanyarazi ubuze, bateri y'inyongera igomba kwikorera compressor ku bushobozi buhagije bwo kugumana ubushyuhe bwa 2-8C kugeza igihe umuriro ugarutse. Ibi ntabwo ari kimwe na bateri isanzwe ya UPS—UPS yagenewe gutanga ingufu z'igihe gito kugira ngo ihagarike neza, ntabwo ikoresha compressor mu minsi ibiri kuri 40C. Icyo twize mu igerageza ryakozwe muri Burkina Faso mu 2021 ni uko kubara ubushobozi bwa bateri bigomba kubara ikibazo gikomeye: firigo yuzuye kuri 40C, imbere yuzuye kuri 4C, ikomeza ubushyuhe mu gihe compressor ikoresha gusa ingufu za bateri. Muri ibyo bihe, bateri y'inyongera y'amasaha 48 igomba gukoresha hafi 60-70% by'ubushobozi bwayo mu masaha 24 ya mbere, igasiga 30-40% by'ubushobozi bwayo ku munsi wa kabiri. Ubutabire bwa batiri ni ingenzi hano—batiri za lithium iron phosphate (LiFePO4) zirusha aside ya lead muri ubu buryo kuko zigumana ingufu zihoraho mu gihe cyose cyo gusohora, bivuze ko compressor idahura n’ihindagurika ry’ingufu rishobora kwangiza ubushyuhe.

Ikoranabuhanga ry'uruhererekane rw'ubukonje rukora cyane ugereranije n'urudaca: Ibimenyetso bigaragaza

Isoko rya firigo zigendanwa zirimo inkingo zigendanwa rigabanyijemo ibice bibiri by'ikoranabuhanga: sisitemu zidakora bakoresha ibikoresho byo guhindura icyiciro (PCM) na sisitemu zikora bakoresha ikoranabuhanga rya compressor cyangwa thermoelectric. Gusobanukirwa ibyo bahuriyeho ni ingenzi mu kugura. Sisitemu zitagira aho zibogamiye (udusanduku twa PCM dukonje) bikora binyuze mu gukonjesha mbere y’uko ipaki y’urubura cyangwa amakatiriji ya PCM mu bubiko bw’ivuriro, hanyuma bikabikwa mu bikoresho bikonjesha bibungabunga ubushyuhe bukabije mu gihe cy’ubushyuhe butunguranye bwo kuvanga. Birahendutse, ntibisaba amashanyarazi mu gihe cyo gutwara, kandi nta buryo bwo gucika intege bw’imashini bigira. Ariko, bitanga igihe ntarengwa cyo kubika ubukonje (ubusanzwe amasaha 24-72 bitewe n’umubare n’ubwiza bw’amapaki y’urubura), ntibishobora kongera gushyirwa mu murima nta gikoresho gikonjesha, kandi ntibitanga uburyo bwo kugenzura ubushyuhe bukora—bivuze ko ubushyuhe bugenda buhoro buhoro bugana mu kirere uko amapaki y’urubura ashonga. Ingaruka z’imikorere ni ingenzi: Sisitemu za PCM zikora neza mu gutwara ziva mu bubiko bw’urubura zijya mu ivuriro, ariko zirananirwa nk’ibikoresho by’ibanze byo kubika mu mavuriro afite ingufu zitizewe kuko zidashobora kubungabunga ubushyuhe igihe kirekire. Tubona amashyirahamwe akora iri kosa iyo aguze amasanduku ya PCM akonje yo kubika mu ivuriro hanyuma agasanga nyuma y’amasaha 48 nta muriro, ubushyuhe bw’imbere bwazamutse hejuru ya 8C. Inkingo zirangiritse, ariko nta nteguza ihari kuko sisitemu idafite umugenzuzi w’ubushyuhe ifite.

Sisitemu zikora (compressor cyangwa thermoelectric) ikoresha ingufu z'amashanyarazi kugira ngo ibungabunge ubushyuhe binyuze mu gukonjesha (compressor) cyangwa Peltier effect (thermoelectric). Zishobora kubungabunga ubushyuhe igihe cyose umuriro uhari, kandi hamwe na bateri y'inyongera y'amasaha 48, zitanga uburinzi nyakuri bw'umuyoboro w'ubukonje uhoraho. Impinduka ni ikiguzi kinini cy'ibanze, imiterere igoye isaba ubushobozi bwo gushyigikira tekiniki, hamwe n'ibisabwa mu gucunga bateri. Inama yacu, ishingiye ku bimenyetso by’ubushakashatsi: Ku nzira zo kugeza ibicuruzwa ku rwego rwa nyuma zifite ingufu z’amashanyarazi zitizewe, sisitemu zikora za compressor zifite bateri y'ingoboka ya LiFePO4 ni amahitamo meza. Twatanze amashami muri za minisiteri z'ubuzima mu bihugu bitandatu byo munsi y'ubutayu bwa Sahara, kandi igipimo gihoraho ni uko ikiguzi cyose cyo gutunga sisitemu zikora—bikubiyemo igihombo cy'inkingo ziturutse ku gutakaza ubushobozi bwa sisitemu—kiri hasi ugereranyije n'inyungu igaragara y'udusanduku tw'inkingo zikonjesha twa PCM. Gutakaza uburyo bumwe bwo gukonjesha bigatuma inkingo 200 zangirika bihenda cyane ugereranyije n'itandukaniro ry'igiciro hagati y'ikoranabuhanga ryombi.

Ibyemezo bya OMS: Amabwiriza Ngengamikorere Udashobora Kurenga

Itsinda Gahunda yo gutanga impamyabumenyi ku rwego rw'isi (OMS Prequalification) (PQ), n'ibifitanye isano WHO EUL (Urutonde rw'Imikoreshereze y'Ibibazo byihutirwa) ku bicuruzwa byo kurwanya icyorezo, ni inzira igenga ibikoresho byo mu ruhererekane rw'inkingo mu ruhererekane rw'ibikoresho by'ubuzima ku isi. Niba ushaka ibikoresho bizakoreshwa muri gahunda ziterwa inkunga na UNICEF, Gavi, Ikigega Mpuzamahanga, cyangwa abandi baterankunga bakomeye b'ibihugu byombi (PEPFAR, USAID, DFID/FCDO), WHO ntabwo ari amahitamo—ni ngombwa ko utanga serivisi. Gahunda ya WHO yo gusuzuma ibikoresho isuzuma ibikoresho ukurikije Ibipimo ngenderwaho by'imikorere, ubuziranenge n'umutekano (PQS) byasobanuwe mu bubiko bw'ibanze bwa WHO PQS. Ku bijyanye na firigo zigendanwa z'inkingo, ibisobanuro bya PQS birimo: PQS E003: Frigo n'ibyuma bikonjesha bitwikiriwe n'urubura n'ibikoreshwa mu gukamura amazi kugira ngo bibike inkingo n'ibivange by'amazi—iki ni cyo cyiciro cy'ingenzi cya firigo zigendanwa z'inkingo. PQS E004: Udusanduku tw’inkingo n’ibikoresho byo gutwara inkingo n’ibindi bikoresho bigabanya ubukana bw’inkingo—bifite akamaro mu bukangurambaga bwo gukingira indwara zigendanwa. PQS E006: Frigo zikoresha imirasire y'izuba—zikoreshwa mu gukoresha imirasire y'izuba mu buryo butaziguye aho imirasire y'izuba ari yo soko y'ibanze y'amashanyarazi.

Uburyo bwo gupima buracyari buhambaye kandi bumara amezi 6-12. Bukubiyemo: Isuzuma ry’ubushyuhe buhamye: Ikizamini cy'iminsi 5 kirimo gucika kw'amashanyarazi, ubushyuhe bwo mu kirere kuva kuri 15C kugeza kuri 43C, n'ingufu zikingurwa. Igenzura ry'imikorere: Gupima uburyo bwo kwirinda gukonjesha inkingo zishobora kwangirika, ubushobozi bwo gukonjesha ku bushyuhe buri hejuru (43C), no gukora neza ku bushyuhe buri hasi (5C). Igenzura ry'imicungire y'ubuziranenge: Igenzura ry'uruganda rigenzura iyubahirizwa rya ISO 13485 n'uburyo ibice by'ingenzi byubahirizwa. Kwemeza urubuga: Mu bihe bimwe na bimwe, OMS ishobora gusaba ko habaho igeragezwa mu buryo nyabwo mbere y’uko icyemezo cyuzuye gitangwa. Impamvu abakora ibicuruzwa babyanga n'impamvu utagomba kwemera impamvu zabo: Uburyo bwo gutanga ibyangombwa bya OMS burahenze kandi butwara igihe kinini. Bitwara abakora ibikoresho by’ibizamini hagati y’amadolari 50,000 na 150,000, ndetse n’igihe cy’ubuhanga kugira ngo barangize igikorwa, kandi bifata amezi 6-18. Bamwe mu bakora ibikoresho batanga ibikoresho by’ibizamini byabanje cyangwa biri mu nzira yo gutanga ibyangombwa byabanje nk’uburyo bwo gukemura ikibazo. Ntukemere ibi. Ishami ririmo gukorwa ntiriba ryujuje ibisabwa mbere—itangwa ry’amasoko rizananirana n’ibisabwa na UNICEF na Gavi. Buri gihe genzura uko WHO ihagaze ku rubuga rwa interineti rwa WHO PQS ukoresheje inomero yihariye y’icyitegererezo cy’ishami, ntabwo ari urutonde rusange rw’abakora ibikoresho gusa.

Ikoranabuhanga rya Compressor ku ruhererekane rw'inkingo: Danfoss nk'igipimo ngenderwaho cy'inganda

Muri firigo zikora zikingira, ikoranabuhanga rya kompreseri ni amahitamo akomeye kandi yizewe cyane. Ibikoresho bya Thermoelectric (Peltier) bifite igipimo cyo gutsindwa gito mu gihe cya laboratwari, ariko bitakaza ubushobozi bwo gukonjesha mu bushyuhe bwinshi bw’ikirere—kandi ahantu hagenewe gukoreshwa kugira ngo bigerweho mu buryo bwa nyuma buri gihe harenga dogere selisiyusi 35. Ku gipimo cya dogere selisiyusi 40, igipimo cya thermoelectric gishobora kugera kuri dogere selisiyusi 12-15 gusa imbere, ibyo bikaba bidahagije ku gipimo cya dogere selisiyusi 2-8. Ku bijyanye no guhitamo compressor, igipimo ngenderwaho cy’inganda ku rugero runini ni Urukurikirane rwa Danfoss BD (cyane cyane moderi za BD35F na BD50F). Impamvu zirasobanutse: Compressor za Danfoss zagenewe gukoreshwa mu gukonjesha, bivuze ko zihanganira gutigita, zagenewe gukora ku nguni kugeza kuri dogere 30 (ni ingenzi mu modoka mu mihanda mibi), kandi zifite uburebure bwa voltage (10.5-17V DC). Zirakora kandi—Danfoss ifite umuyoboro mpuzamahanga w’ibigo byemewe bishobora gutanga compressor zisimbura n’ubufasha mu bya tekiniki mu bihugu birenga 120.

Iyo dushyizeho firigo zacu zigendanwa zo mu bwoko bwa firigo zo mu bwoko bwa Danfoss BD series compressors, bateri za LiFePO4 zisanzwe zifite ubushobozi bwo gukora amasaha 48, hamwe n'ibikoresho byo kugenzura ubushyuhe byo hanze byujuje ibisabwa na WHO PQS ku bikoresho bigenzura ubushyuhe. Dufata aya mahitamo ku buryo bweruye kuko ubundi buryo—compressor itari iy'ikirango ifite bateri ya aside ya lead—bunanirana cyane mu kazi. Twanditse igipimo cy'igaruka ry'imashini zirinda ubushyuhe zitari Danfoss ziruta inshuro enye ibikoresho byacu bisanzwe.

Guteganya ubushobozi: Guhuza ingano y'ibice n'umutwaro w'akazi k'ivuriro

Guhitamo ubushobozi bwo kubika neza ni kimwe mu makosa akunze kugaragara mu kugura inkingo zikonje. Ingaruka zo kubikora nabi mu cyerekezo icyo ari cyo cyose ni zikomeye: icyuma gito ntigishobora kubika ibikoresho bihagije byo gukwirakwiza inkingo buri kwezi, mu gihe icyuma kinini gitakaza ingufu, gitwara amafaranga menshi kuruta uko bikenewe, kandi gishobora kugira ubushyuhe bwinshi bitewe n'ihindagurika rito ry'inkingo. Ububasha busabwa bushingiye ku bintu bitatu: Abaturage bireba: Umubare w'abantu bakirwa n'ivuriro, ni na wo ugena ingano y'inkingo zitangwa buri mwaka. Ingano y'agacupa k'urukingo: Uducupa tw’ibipimo byinshi (ubusanzwe doze 10 cyangwa 20 kuri buri gacupa) duhindura cyane ingano y’ububiko ugereranije n’uducupa tw’ibipimo bimwe. Ibisabwa ku isanduku ya buffer: Minisiteri nyinshi z'ubuzima zisaba iminsi 30-60 yo kubika ibicuruzwa kugira ngo zirebe itandukaniro ry'uburyo bwo gutanga ibicuruzwa n'ubwiyongere bw'ibikenewe mu bukangurambaga.

Ingero zifatika zo gupima ingano: Ivuriro (abaturage 5,000-10,000): Ibikoresho bya litiro 20-40, bikunze gutanga inkingo 50-100 buri kwezi. Ivuriro ry'Akarere (abaturage 10.000-50.000): Ibikoresho bya litiro 40-80, bitanga inkingo 100-500 buri kwezi hamwe n'inkingo zisanzwe. Icyumba gikonjesha cy’ibitaro by’akarere/akarere: Litiro 80-150 cyangwa zirenga, kugira ngo habeho ububiko bw'inkingo zisanzwe n'izikoreshwa mu bukangurambaga. Ku bafatanyabikorwa benshi b'ubuzima ku isi, 40-60L niyo ikunze kuvugwa cyane kuko ari nini bihagije kugira ngo ikoreshwe mu gihe cy'iminsi 30 yo kubika inkingo ku rwego rw'akarere mu gihe ikomeza kwimurwa bihagije kugira ngo ifatwe ijya ahantu hatandukanye. Imiterere y'imbere nayo ni ingenzi—gusaba ko habaho shelving ishobora guhindurwa n'urugi rushobora guhindurwa (kugira ngo icyuma gishobore gushyirwa mu mfuruka zifite umwanya muto wo kuzunguruka) ni ibisanzwe mu bigo by'ubuvuzi bishya.

Ishusho ya Bateri y'amasaha 48: Kubara ubushobozi n'imiterere y'aho ikoreshwa

Ntabwo byose bivugwa kuri bateri y'amasaha 48 bingana. Igihe bateri ikora mu miterere nyayo giterwa n'ibintu byinshi protocole zo gupima zishobora kudakoresha neza. Ubuhanga bwa bateri: Bateri za Lithium iron phosphate (LiFePO4) zitanga voltage ihamye mu gihe cyose cyo gusohora ugereranije na bateri za lead-acid. Ibi ni ingenzi kuko compressor ikora kuri 11.0V (iherezo ry'isohoka rya lead-acid) ikora bitandukanye n'ikora kuri 12.5V (LiFePO4 mu gihe cyose cyo gusohora). Turasaba LiFePO4 nk'uburyo ntarengwa bwo gukoresha mu gihe cya nyuma. Igabanuka ry'ubushyuhe bw'ikirere: Ubushobozi bwa batiri buragabanuka iyo ubushyuhe buri hejuru. Batiri ifite amanota 48 kuri 25C ishobora gutanga amasaha 30-36 gusa kuri 40C. Saba umurongo ugena uko batiri ihagaze hanyuma ugenzure niba hari amasaha 48 ku bushyuhe ntarengwa bw’ikirere buteganijwe mu gace kawe. Kura umwirondoro: Igihe bateri ikora ntabwo ari kimwe iyo yuzuye ugereranyije n'igihe ikora igice cy'umutwaro. Frigo yuzuye igice cy'umutwaro irimo inkingo zishyushye mu gihe cyo kuyitanga izakenera igihe kinini cyo kuyikoresha kurusha iyo yuzuye ku bushyuhe buhamye. Saba ibisobanuro by'ubushobozi bwa bateri mu gihe cy'umutwaro mubi cyane. Igihe cyo kongera gusharija: Nyuma yo gucika intege k'umuyoboro w'amashanyarazi, bateri yo kugarura umuriro igomba kongera gukoreshwa mu gihe habayeho guhagarara gukomeye. Bateri imara amasaha 48 isaba amasaha 24 kugira ngo yongere ikoreshwe neza ni ikibazo niba ingufu z'umuyoboro w'amashanyarazi zihoraho. Turakugira inama yo gushyiraho ibikoresho bifite ubushobozi bwo kongera gukoresha umuriro vuba (gushyiramo umuriro mu masaha 8-12 nyuma yo kugarura umuriro w'amashanyarazi) kugira ngo witegure guhagarara gukomeye gukomeye.

Frigo zacu zigendanwa zo mu bwoko bwa W-Series zakozwe zifite bateri y’inyongera ya LiFePO4 imara amasaha 48 nk’uko bisanzwe, hamwe na sisitemu yo gucunga bateri yashyizweho kugira ngo igumane ubushobozi bwo gusharija 70% ndetse no mu gihe cy’igihe kirekire cyo gukora ubushyuhe bwinshi. Twashyize izi mashini mu miterere y’ubutaka muri Nijeriya, Kenya, Myanmar na Peru—kandi amakuru yo mu murima yemeza ko amabwiriza y’amasaha 48 ashobora kugerwaho kuri 40C hamwe n’umutwaro wuzuye wa firigo.

Urusobe rw'Ibicuruzwa n'Amasoko: Aho wakura n'icyo wakwemeza

Gutanga serivisi z'ubuzima ku isi bifite ibisabwa byihariye mu ruhererekane rw'ibicuruzwa bitandukanye n'ubucuruzi busanzwe. Ibyemezo bya OMS mbere na mbere: Ishami iryo ari ryo ryose rikoreshwa muri UNICEF, Gavi, cyangwa gahunda zikomeye ziterwa inkunga n’abaterankunga b’ibihugu byombi rigomba kugaragara ku rutonde rw’abashinzwe gutanga ibizamini bya OMS. Emeza inomero yihariye y’icyitegererezo ku rubuga rwa WHO PQS, ntabwo ari uwakoze gusa. Icyemezo cya ISO 13485: Bikenewe cyane nk'uburyo bwo gutanga serivisi zo gucunga ubuziranenge bw'ibikoresho by'ubuvuzi. Iri hame risaba gukurikirana ibice byabyo mu buryo bwanditse, kugenzura ubuziranenge buri gihe, no gutanga raporo ku byabaye nabi. Saba icyemezo cya ISO 13485 cy'uruganda hanyuma ugishyire mu maboko y'umwanditsi wabitanze. Ibisabwa mu mategeko yihariye y'igihugu: Ibihugu byinshi bifite ibisabwa mu kugenzura ibikoresho bikoreshwa mu buvuzi. NAFDAC yo muri Nijeriya, PPB yo muri Kenya, na CDSCO yo mu Buhinde byose bifite inzira zo kwemeza zishobora gukorana n'iyubahirizwa rya OMS cyangwa nyuma yaryo. Niba urimo gushaka gahunda y'igihugu runaka, genzura imiterere y'amategeko n'ikigo cy'igihugu gishinzwe kugenzura. Ibikorwa remezo bya serivisi n'inkunga: Frigo igendanwa ikoreshwa mu gukingira idafite ubufasha bwa tekiniki ni ikintu kidashoboka. Turasaba cyane gushyiraho ibikoresho biva mu nganda zishinzwe imiyoboro ya serivisi mu bihugu zigenewe gukwirakwiza serivisi. Danfoss ifite ibigo byemewe mu bihugu byinshi byo munsi y'ubutayu bwa Sahara, bivuze ko gusimbuza no gusana compressor bishoboka ku rwego rw'uturere. Garanti n'ibice bisimbura: Garanti zisanzwe z’ubucuruzi (amezi 12-24) ntizihagije ku bijyanye n’amasoko mpuzamahanga y’ubuzima, akenshi zigira imyaka 3-5 kuva ku isoko kugeza ku ishyirwa mu bikorwa kugeza ku gusimburwa. Turakugira inama yo gushyiraho garanti nibura y’amezi 36 no kugenzura ko ibikoresho by’ingenzi (compressor, control board, bateri) biboneka mu ruhererekane rw’ibikoresho byo mu karere.

Urutonde rw'ibicuruzwa bya porogaramu za Cold Chain

Ku bigo bisuzuma firigo zigendanwa zo gutanga inkingo ku buryo bworoshye, dutanga urutonde rw'ibicuruzwa bibiri byagenewe uburyo butandukanye bwo kuzikoresha:

Urukurikirane rwa K — Umurongo wacu muto w’imiyoboro ikonje, ukwiriye ibigo nderabuzima n’amavuriro ya kure afite ibyangombwa biri hagati yo kubika (20-40L). CE + ETL ifite icyemezo cya kabiri hamwe na kompreseri za Danfoss hamwe n’ubushyuhe bwubatswemo. K-Series ikora nk'ahantu ho kwinjira mu bigo byubaka ubushobozi bwo gukoresha imiyoboro ikonje mu turere tw’icyaro, cyane cyane mu gushyiraho imiyoboro y’amashanyarazi ikoresha ikirere gishyushye aho amashanyarazi yizewe ku rugero ruciriritse.

Urukurikirane rwa W — Umurongo wacu w’inkingo zikonjesha w’umwuga, wagenewe by’umwihariko porogaramu z’ubuzima ku isi ndetse n’ibisabwa na OMS mbere y’uko itangwa ry’ibizamini. Ubushobozi kuva kuri 40-80L, hamwe na bateri y’inyongera ya LiFePO4 y’amasaha 48, compressor ya Danfoss BD, hamwe n’ubushyuhe bujyanye na PQS. W-Series ni yo mahitamo meza kuri gahunda zo gutanga amasoko za UNICEF na Gavi, minisiteri z’ubuzima mu turere, n’imiryango itegamiye kuri leta ikorera muri Afurika yo munsi y’ubutayu bwa Sahara, Aziya y’Amajyepfo y’Epfo, no mu cyaro cya Amerika y’Epfo.
