Ikosa rya firigo ry’ubucuruzi risobanura firigo ikoreshwa, ibice bitari ibyayo, ibibazo by’ibice byayo biterwa n’ibibazo bitandukanye. Ifaranga ry’ubucuruzi mu kuvugurura, rigomba kubanza gukuramo iryo kosa rya firigo, kugira ngo ivugurura rikore neza. Ibi bikurikira birakubwira amakosa ya firigo akunze kugaragara mu firigo z’ubucuruzi.
Gukoresha nabi akabati gakonje, gushyirwa ahantu hatameze neza, guhumeka nabi, ivumbi ryiyongera cyane kandi ntirisukurwe ku gihe, ibi bizatuma ubushyuhe bwa kondensa bugabanuka nabi, bityo ingaruka zo gukonjesha mu kabati gakonje zigahinduka mbi.
Ibiryo byinshi bibitswe mu gikonjesha, bibangamira urujya n'uruza rw'umwuka ukonje, bizatuma ubushyuhe bw'akabati buba buri hejuru. Gufungura kenshi urugi rw'akabati gakonje, compressor ku gihe nta kabuza izongera gukoreshwa.
Compressor iba ishyushye iyo akabati gakonje karimo gukora, kandi compressor ihora ikuraho ubushyuhe bwinjizwa na firigo mu cyuma gishyushya binyuze muri condenser. Bityo ubushyuhe bw'agasanduku k'icyuma gishyushya muri rusange nabwo bufite dogere 80℃kugeza kuri 90℃, ari na yo miterere y'akazi kayo.
Friji ikoreshwa muri firiji ntikonjesha cyangwa ngo ikoreshwe, iki kintu kigaragaza ko firiji ifite ubushuhe bwinshi, kandi ubushyuhe buri hejuru. Ubushuhe bushobora guturuka ku biribwa, ariko nanone bushobora kuba bufitanye isano inshuro nyinshi no gufungura urugi, cyane cyane firiji ifite umuryango umwe ishobora gutera ibintu nk'ibyo. Umuti ni ukuvanaho urubura ku buso bwa firiji, hanyuma ugahindura thermostat kugira ngo ugabanye ubushyuhe buri muri firiji.
Akabati gakonje gakora akazi ko mu kabati gatanga ijwi ry'amazi, ari na ryo koranabuhanga rya refrigerant mu muyoboro, iyo amazi agana kuri evaporator, imiterere yayo iba ari amazi, amazi asohoka muri refrigerant azatanga ijwi ryumvikana ry'amazi, rimwe na rimwe mu gihe cyo kuzimya umuriro ashobora kumvikana nyuma gato. Ibi biterwa nuko ikibazo cyo kutagira umwuka mwiza giterwa n'ijwi risanzwe.
Ubushyuhe busanzwe bw'igikonoshwa cya firigo, icyuma gishyushya kiri mu kabati, ubushyuhe bwinjiye mu kabati n'ubushyuhe bw'akazi bwa compressor buri hanze ya firigo ikonje, iraseswa. Kuri ubu, icyuma gishyushya kiri inyuma ya firigo, ikindi kihishe mu mpande z'agasanduku. Ubushyuhe busanzwe bushira, ubushyuhe bw'ubuso bwa firigo bushobora kugera kuri dogere 50℃kugeza kuri 60℃Bityo rero, igikonoshwa cy'ubushyuhe bwa firigo yo mu bucuruzi ni ikintu gisanzwe.
Ubushyuhe bwa firigo mu bihe bitandukanye buratandukanye, firigo ifite icyuma gishyushya n'icyuma gikoresha ingufu nke, gikoreshwa mu gihe cy'itumba ku gishyushya cy'akabati, gikwiye kunoza ubushyuhe bw'akabati, kugira ngo gikemure ubushyuhe bw'ikirere mu gihe cy'itumba ni buke, thermostat ntiyoroshye gukora kugira ngo itume compressor itangira gukora. Iyo ubushyuhe budafunze, hashobora kubaho ingaruka mbi zo gukonjesha.
Dukurikije amahame y’igihugu, ihindagurika ry’amashanyarazi mu gikonjesha ryemerewe kuva kuri 187 V kugeza kuri 242 V. Ingufu zidahagije z’amashanyarazi cyangwa aho zihurira n’imashini zikoresha amashanyarazi n’isoko, muri ibyo byombi, bishobora gutuma ingufu zongewe mu gikonjesha cy’ubucuruzi ziba nke ugereranyije n’ingufu zikora, kandi gikonjesha ntigitangire cyangwa ngo gitangire kenshi. Iyo ihindagurika ry’amashanyarazi ari rinini cyane, ni byiza kudakoresha.
