Idan aka fara amfani da na'urar sanyaya sukurori, abu na farko da za a sani shi ne ko tsarin sanyaya yana aiki yadda ya kamata. Ga taƙaitaccen bayani game da abubuwan da ke ciki da alamun aikin yau da kullun, kuma ga abin da za a yi la'akari da shi kawai:
Ruwan sanyaya na na'urar sanyaya ya kamata ya isa, matsin lamba na ruwa ya kamata ya wuce 0.12MPa, kuma zafin ruwan bai kamata ya yi yawa ba.
Ga na'urorin sanyaya sikirin, karanta ma'aunin matsin lamba na famfon mai ya kamata ya zama sama da 0.15 ~ 0.3MPa fiye da matsin lamba na shaye-shaye.

Zafin fitar da na'urar sanyaya daki. Ammonia da R22 ba sa wuce 135°C, kuma idan zafin iskar gas ɗin da ke fitarwa ya ƙara ƙaruwa, zai yi ƙanƙanta sosai idan aka kwatanta da wurin walƙiya na man sanyaya (160°C), wanda ba shi da kyau ga kayan aiki. Saboda haka, daga mahangar amfani, zafin hayakin bai kamata ya yi yawa ba, kuma idan ya yi yawa, ya kamata a dakatar da shi don gano dalilin.
Matsayin matsin lamba na matsewa. Ana ƙayyade shi ne bisa ga tushen ruwa, tsarin matsewa da kuma firiji da aka yi amfani da shi. Matsayin ruwa na ma'ajiyar bai kamata ya zama ƙasa da kashi ɗaya bisa uku na alamar matakin ruwa ba, kuma matakin mai na ma'ajiyar bai kamata ya zama ƙasa da layin tsakiya na kwance na taga mai nuna ba.
Bututun mai da ke mayar da mai ta atomatik na mai raba mai fluorine abu ne na yau da kullun idan yana da sanyi da zafi, kuma zagayowar sanyi da zafi yana ɗaukar kimanin awa 1. Bai kamata a sami bambanci a zahiri a zafin jiki ba kafin da bayan matatar bututun ruwa. Bai kamata a sami sanyi ba, in ba haka ba za a toshe shi. Firijiyar fluorine ya kamata ta kasance mai sanyi a gefen lebur kuma ta yi zafi a gefen bushewa. Haɗin tsarin fluorine bai kamata ya zube mai ba, wanda ke nufin ɓullar fluorine.
Idan aka taɓa na'urar sanyaya iska a kwance yayin aiki, ya kamata ɓangaren sama ya yi zafi, ɓangaren ƙasa kuma ya yi sanyi. Haɗin sanyi da zafi shine matakin ruwan sanyi. Mai raba mai shi ma yana da zafi a ɓangaren sama, kuma ɓangaren ƙasan bai yi zafi sosai ba. Bawul ɗin aminci ko bawul ɗin wucewa na firiji ya kamata ya ji sanyi a ƙarshen ƙaramin matsin lamba, idan ba sanyi ba ne, yana nufin iska mai ƙarfi da ƙarancin matsin lamba tana zubewa.
A lokacin aiki, matsin tururin ya kamata ya yi kama da matsin tsotsa, kuma matsin shaye-shaye a ƙarshen matsin lamba mai girma ya kamata ya yi kama da matsin lamba mai narkewa da matsin lambar mai karɓar ruwa. Idan ba haka ba, to ba shi da kyau.
