Makabati afiriji a m’masitolo akuluakulu amagwiritsidwa ntchito m’firiji ya chakudya, posungiramo madzi oundana, ndi m’minda ina. Malo ogulitsira amakhala ndi makabati osachepera atatu kapena kupitilira apo, ambiri mwa iwo ndi zitseko ziwiri, zitseko zotsetsereka, ndi mitundu ina. Ubwino umakwaniritsa miyezo yapadziko lonse lapansi yachitetezo. Malingana ndi kafukufuku wamsika, kabati ya firiji imakhala ndi moyo wosachepera zaka 10, ndipo nthawi zambiri zolephera zimakhala zochepa.
Kugulidwa kwa makabati oyimirira m'malo ogulitsira kuyenera kukwaniritsa zofunikira. Kwa ogwiritsa ntchito wamba, moyo wautumiki uyenera kukhala wautali. Malinga ndi akatswiri, magawo monga kugwiritsa ntchito mphamvu ya compressor, kachulukidwe kazinthu, komanso kuyesa kukalamba ayenera kukhala oyenerera.
Kusanthula kosavuta kwa kugwiritsa ntchito mphamvu kumawonetsa kuti mitundu yosiyanasiyana ndi mitundu yosiyanasiyana ya ma compressor ofukula amadya mphamvu zosiyanasiyana. Zowona, kugwiritsa ntchito mphamvu kumayenderana mwachindunji ndi magwiridwe antchito. M'mawu a layman, kugwiritsa ntchito mphamvu kwambiri, kumapangitsanso kuzizira bwino, komanso mosemphanitsa. Tikayang'ana pa khalidwe, ngati mphamvu yogwiritsira ntchito mphamvu ndipamwamba komanso kuzizira kozizira kumakhala kochepa, sikuli koyenera, komwe kungathe kukhazikitsidwa ndi deta yambiri yoyesera.
Kachulukidwe kazinthu ndiyenso index yamtundu wa nduna. Kuchokera pamawonekedwe a fuselage gulu, ambiri a iwo amapangidwa ndi zitsulo zosapanga dzimbiri. Tonse tikudziwa kuti chitsulo chosapanga dzimbiri chimapangidwa ndi chromium, nickel, faifi tambala, manganese, silicon ndi zinthu zina. Zinthu zosiyanasiyana zimakhudza kwambiri. Mwachitsanzo, ngati chitsulo cha nickel sichikukwanira, kulimba, ductility ndi kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri kudzachepa. Ngati zomwe zili mu chromium sizili bwino, kukana kwa okosijeni kumachepa, zomwe zimayambitsa dzimbiri ndi mavuto ena.
Chotsatira ndi kuyesa ukalamba. Kabati imapangidwa molingana ndi dongosolo lokonzedweratu, ndipo mayeso okalamba amafunikira. Ngati mayesowo alephera, sizingafanane ndi muyezo ndipo sizingalowe pamsika. Njira yoyesera ndiyonso chizindikiro chofunikira chowunikira khalidwe. Kuti mudziwe zambiri, chonde onani buku lenileni la nduna. Zoyeserera zonse ndi izi (zongongoyang'ana):
(1) Dziwani nthawi ya moyo wa ma compressor amphamvu kwambiri
(2) Yesani kuchuluka kwa nthawi yomwe nduna yoyimirira imatsegula ndikutseka chitseko
(3) Kuyesa kukana kwa dzimbiri m'malo osiyanasiyana
(4) Onani ngati kutentha kwaziziritsa ndi magwiridwe antchito ndizokhazikika
M'mafakitole enieni, mayeso osiyanasiyana okalamba a nduna amakhala ndi miyezo yosiyana, ndipo ena omwe ali ndi ntchito zambiri amayenera kuyesedwa chimodzi ndi chimodzi, monga kuzirala mwachangu, kutsekereza, ndi ntchito zina.
