Ubushobozi bwo gukonjesha ntibushobora kuzuza ibisabwa mu bubiko
(ubushobozi buke bwa compressor)
Hari impamvu ebyiri z'ingenzi zituma habaho kubura urujya n'uruza rw'ibinyabutabire muri firigo.
Ubwa mbere, icyuma gikonjesha ntabwo gihagije, kandi muri iki gihe hakenewe ingano ihagije ya firigo;
Indi mpamvu ni uko hari amazi menshi asohoka muri firigo. Kugira ngo umenye icyo kibazo, ugomba kubanza gushaka aho amazi asohoka, ukibanda ku kugenzura aho buri muyoboro na vali bihurira, hanyuma wuzuze firigo ihagije nyuma yo gusana ibice byamenetse.
Kutagira ubushobozi bwo gukonjesha
(Ubunini budahagije bwa firigo muri sisitemu)
Ingano idahagije ya firigo muri sisitemu igira ingaruka zitaziguye ku rujya rwa firigo mu cyuma gishyushya. Iyo ifunguka rya valvu yo kwagura ari rinini cyane, valvu yo kwagura irahindurwa nabi cyangwa igafungwa. Igipimo cy'amazi yo kwagura irangi ni kinini cyane, igipimo cy'amazi yo kwagura n'ubushyuhe bw'amazi nabyo biriyongera, kandi igipimo cyo kumanuka k'ubushyuhe bw'ububiko buragabanuka; muri icyo gihe, iyo valvu yo kwagura ifunguwe ari nto cyane cyangwa igafungwa, igipimo cy'amazi yo kwagura iragabanuka, kandi ubushobozi bwo gukonjesha bw'isi nabwo buriyongera uko ubushyuhe bw'ububiko bugabanuka. Muri rusange, umuntu ashobora kumenya niba igipimo cy'amazi yo kwagura irangi gikwiye hagendewe ku gipimo cy'amazi yo kwagura, ubushyuhe bwo kwagura n'uko umuyoboro wo gukurura umeze. Kuziba kw'imvange yo kwagura ni ikintu cy'ingenzi bigira ingaruka ku rujya rwa firigo. Impamvu nyamukuru zitera kuziba kw'imvange yo kwagura ni ukuziba kw'urubura no kuziba kwanduye. Kuziba kw'urubura ni ukubera ko icyuma cyumisha kitaba cyiza, kandi firigo irimo ubushuhe. Iyo inyura muri valve yo kwagura, ubushyuhe bugabanuka munsi ya 0 °C, kandi ubushuhe buri muri firigo bugahinduka urubura bugafunga umwobo wa valve yo ku mugozi; gufunga kwanduye biterwa nuko hari umwanda mwinshi wirundanyije ku cyuma gipima icyuma aho valve yo kwagura yinjira, kandi firigo ntiyoroshye kandi yoroshye, bigatuma ifunga.
Urugendo rw'ibikoresho bikonjesha ni runini cyane cyangwa ruto cyane
(gukosora nabi cyangwa kuziba kwa valve yo kwagura)
Igipimo cyo kohereza ubushyuhe kizagabanuka, amavuta yo gukonjesha amaze gushyirwa imbere n'inyuma y'umuyoboro w'ubushyuhe wa evaporator. Mu buryo nk'ubwo, niba hari umwuka mwinshi mu muyoboro w'ubushyuhe, agace ko guhanahana ubushyuhe ka evaporator kazagabanuka, ubushobozi bwo kohereza ubushyuhe nabwo buzagabanuka cyane, kandi umuvuduko wo kugabanuka k'ubushyuhe bw'ububiko uzagabanuka. Kubwibyo, mu mikorere ya buri munsi no kubungabunga, hakwiye kwitabwaho gukuraho ku gihe ibyanduza by'amavuta imbere n'inyuma y'umuyoboro w'ubushyuhe wa evaporator no gusohora umwuka mu muyoboro w'ubushyuhe kugira ngo hongerwe ubushobozi bwo kohereza ubushyuhe bwa evaporator.
Ingaruka zo kohereza ubushyuhe zigabanuka
(Hari amavuta menshi yo mu mwuka cyangwa ayo muri firigo mu cyuma gishyushya umwuka)
Ibi ahanini biterwa nuko urwego rw'ubukonje ruri inyuma y'icyuma gishyushya ibintu (evaporator) runini cyane cyangwa ivumbi rikaba rikabije cyane. Kubera ko ubushyuhe bwo hanze bw'icyuma gishyushya ibintu mu bubiko bukonje busanzwe buri munsi ya 0°C, indi mpamvu ikomeye ituma ubushyuhe bwo kubika bugabanuka buhoro ni uko icyuma gishyushya ibintu mu buryo budakoresha ubushyuhe bwinshi. Ubushyuhe bwo mu bubiko buri hejuru, kandi ubushuhe buri mu kirere biroroshye cyane gukonja cyangwa ndetse no gukonja ku buso bw'icyuma gishyushya ibintu, ibyo bigira ingaruka ku ngaruka zo kohereza ubushyuhe bw'icyuma gishyushya ibintu. Kugira ngo hirindwe ko urwego rw'ubukonje rwo hanze rw'icyuma gishyushya ibintu rudakomera cyane, rugomba gukurwaho buri gihe.
Dore uburyo bubiri bworoshye bwo gukurura:
① Hagarika kugira ngo unyungure. Ni ukuvuga guhagarika imikorere ya compressor, fungura umuryango w'ububiko, ureke ubushyuhe bw'ububiko buzamuke, hanyuma wongere utangire compressor nyuma y'uko urwego rw'ubukonje rushonge.
②Amavuta yo gukaraba. Nyuma yo gukura ibicuruzwa mu bubiko, sukura neza hejuru y'umuyoboro wa evaporator n'amazi yo mu igorofa afite ubushyuhe bwinshi kugira ngo ishongeshe cyangwa igwe ku rukuta rw'ubukonje. Uretse ingaruka mbi zo kohereza ubushyuhe bw'i evaporator bitewe n'ubukonje bwinshi, ubuso bw'i evaporator buba bunini cyane bitewe no kwangirika kw'igihe gito, kandi ubushobozi bwo kohereza ubushyuhe nabwo buzagabanuka cyane.
Ingaruka zo kohereza ubushyuhe zigabanuka
(Ubuso bw'icyuma gishyushya ibintu bukonje cyane cyangwa bufite ivumbi ryinshi cyane)
Ingaruka mbi zo gukingira ubushyuhe n'ingaruka mbi zo gukingira ubushyuhe, hamwe n'imikorere mibi yo gukingira ubushyuhe biterwa n'ubugari budahagije bw'ibice by'ubushyuhe nk'imiyoboro n'inkuta zo gukingira ubushyuhe mu bubiko. Biterwa ahanini no guhitamo nabi ubugari bw'ibice by'ubushyuhe mu gihe cyo gushushanya cyangwa ubwiza buke bw'ibikoresho byo gukingira ubushyuhe mu gihe cyo kubaka.
Byongeye kandi, mu gihe cyo kubaka no gukoresha, uburyo bwo gukingira ubushyuhe n'imikorere y'ibikoresho byo gukingira ubushyuhe bishobora kwangirika, bigatuma urwego rwo gukingira ubushyuhe ruhinduka ubushuhe, rugahinduka cyangwa rukangirika.
Indi mpamvu y'ingenzi ituma ubukonje bugabanuka cyane ni ukudakora neza kw'ububiko, kandi umwuka ushyushye winjira mu bubiko bitewe n'amazi yavuye mu bubiko. Muri rusange, iyo hari ubushyuhe ku rukuta rw'ububiko cyangwa ku rukuta rw'ububiko bukonje, bivuze ko ubukonje budafunze neza.
Byongeye kandi, gufungura no gufunga kenshi umuryango w’ububiko cyangwa abantu benshi binjira mu bubiko nabyo byongera igihombo cy’ubushobozi bwo gukonjesha mu bubiko. Urugi rw’ububiko rugomba kubuzwa gufungura uko bishoboka kose kugira ngo hirindwe ko umwuka ushyushye mwinshi winjira mu bubiko. Birumvikana ko iyo ububiko bukunze kuba burimo ibintu byinshi cyangwa ibikoresho byinshi binini cyane, ubushyuhe buriyongera cyane, kandi muri rusange bifata igihe kirekire kugira ngo bukonje kugeza ku bushyuhe bwagenwe.
bitera igihombo kinini mu bukonje
(ububiko bukonje bitewe no kutarinda ubushyuhe cyangwa kudakora neza kw'ifunga)
Ibice nk'imigozi ya silindiri n'impeta za piston birashaje cyane, kandi compressor iba ikora by'agateganyo. Iyo aho ihuzwa ryiyongera, imikorere yo gufunga izagabanuka uko bikwiye, coefficient yo kohereza gaze ya compressor nayo izagabanuka, kandi ubushobozi bwo gukonjesha buzagabanuka. Iyo ubushobozi bwo gukonjesha buri munsi y'umutwaro w'ubushyuhe bw'ububiko, ubushyuhe bw'ububiko buzagabanuka buhoro buhoro. Ubushobozi bwo gukonjesha bwa compressor bushobora kugenwa neza hagendewe ku kureba imbaraga zo gukurura no gusohora za compressor. Iyo ubushobozi bwo gukonjesha bwa compressor bugabanutse, uburyo bukunze gukoreshwa ni ugusimbuza liner ya silindiri n'impeta ya piston ya compressor. Iyo gusimbuza bidakora, hari ibindi bintu bigomba kwitabwaho, cyangwa se no gusenya no kugenzura kugira ngo haveho ibintu byangiritse.
