Hano haribintu bibiri mumasanduku yimodoka, kimwe nikigega gishyushye, kimwe nicyuma gikonjesha, amazi mumazi yimodoka arashyushye, gutembera mumatara ashyushye, umuyaga uhuhwa numufana nubushyuhe umwuka, kandi iyo ufunguye firigo, ikigega gishyushye kizahagarika amazi, icyuma gikonjesha cyatangiye gukora, firigo ya compressor igitutu ikonjesha, ikava mu kirere gikonje gikonje
Isanduku yo guhinduranya ibinyabiziga ni moteri yimodoka hamwe nicyuma gikonjesha imashini. Imikorere yisanduku yo guhumeka yubukonje bwimodoka nugukora firigo ikava mumazi ikajya kuri gaze (nukuvuga evaporation), ikurura ubushyuhe bwinshi hirya no hino, hanyuma ubushyuhe buke hamwe numwuka muke wa firigo muke muri compressor, hamwe ninzinguzingo ya inzira yo kugera ku ntego y'ubushyuhe buke. Mu mpeshyi kugirango itange ahantu heza ho kugendera kubayirimo, gabanya imbaraga zumunaniro wumushoferi, guteza imbere umutekano wo gutwara
