Icyumba gikonjesha ikirere gikonje gikoreshwa muburyo bukoreshwa: koresha umwuka hamwe nubushyuhe buke nubushuhe buke, menya kuzenguruka ku gahato hagati yibintu, buhoro buhoro ugabanya ibintu bitose kugirango ugere kurwego rusabwa.Muburyo bwo kuzenguruka ku gahato, ubushyuhe buke hamwe n’umwuka muke uhora ukurura ubuhehere buva hejuru y’ibintu, umwuka wuzuye unyura mu kirere, bitewe no guhumeka kwa firigo, ubushyuhe bw’ubushyuhe bwa moteri bugabanuka munsi yubushyuhe bwikirere. Umwuka urakonje, havamo ubuhehere, nyuma yubushuhe bwakuweho busohorwa nuwakusanyije amazi. Ubushyuhe buke hamwe nubushyuhe buke noneho byongera kwinjira muri kondenseri, aho umwuka ushyutswe nubushyuhe bwo hejuru bwa gaze ya firigo ivuye muri compressor, bigakora umwuka wumye, hanyuma ikavanga numwuka wuzuye kugirango ubyare ubushyuhe buke numwuka muke muto, uzenguruka. inshuro nyinshi. Ibintu byumye byumuyaga ukonje ntabwo bikomeza ubwiza bwumwimerere gusa, ahubwo binoroha kubipakira, kubika no gutwara.
