1. Kutaya kwa firiji
[Kusanthula Zolakwa]Pambuyo pa firiji kutuluka m'dongosolo, mphamvu yoziziritsa imakhala yosakwanira, kutsekemera ndi kutulutsa mpweya kumakhala kochepa, ndipo valavu yowonjezera imatha kumva phokoso la "squeak" lapamwamba kwambiri kuposa nthawi zonse. Evaporator ilibe chisanu kapena chisanu choyandama choyandama. Ngati dzenje la valve yowonjezera likukulitsidwa, kukakamiza koyamwa sikungasinthe kwambiri. Pambuyo pozimitsa, kupanikizika kofanana mu dongosolo nthawi zambiri kumakhala kotsika poyerekeza ndi kutentha komwe kumayenderana ndi kutentha komweko.
[Njira]Pambuyo pa kutha kwa firiji, musathamangire kudzaza dongosolo ndi refrigerant. M'malo mwake, muyenera kupeza malo otayira nthawi yomweyo ndikudzazanso firiji mukakonza.
2. Firiji yochuluka kwambiri imaperekedwa pambuyo pokonza
[Kusanthula zolakwika]Kuchuluka kwa refrigerant yomwe imayikidwa mufiriji mutatha kukonza kupitilira mphamvu ya dongosolo, refrigerant imatenga voliyumu ina ya condenser, kuchepetsa malo oziziritsira kutentha, ndikuchepetsa kuzizira bwino, ndipo kukakamiza koyamwa ndi kutulutsa kumakhala kwakukulu. . Pakukakamiza kwanthawi zonse, evaporator simazizira, ndipo kutentha m'nyumba yosungiramo katundu kumachepa.
[Njira]Malingana ndi ndondomeko yogwiritsira ntchito, refrigerant yowonjezera idzatulutsidwa pa valve yothamanga kwambiri pambuyo pa mphindi zochepa zotsekedwa, ndipo mpweya wotsalira mu dongosolo ukhoza kumasulidwa panthawiyi.
3. Muli mpweya mufiriji
[Kusanthula zolakwika]Mpweya mufiriji udzachepetsa mphamvu ya firiji. Chochitika chodziwika bwino ndi chakuti kuthamanga kwa kuyamwa ndi kutulutsa kumawonjezeka (koma kutsekemera kotulutsa sikunapitirire mtengo wovomerezeka), ndipo kutentha kuchokera ku compressor outlet kupita ku condenser inlet kumawonjezeka kwambiri. Chifukwa cha mpweya mu dongosolo, kuthamanga kwa mpweya ndi kutentha kwa mpweya kumawonjezeka.
[Njira]Mungathe kumasula mpweya kuchokera ku valavu yotseka yothamanga kwambiri kangapo mphindi zochepa mutatseka, ndipo mukhoza kudzaza firiji moyenerera malinga ndi momwe zilili.
4. Kuchita bwino kwa kompresa
[Kusanthula Zolakwa]Kutsika kocheperako kwa kompresa ya firiji kumatanthawuza kuchepa kwa kusamuka kwenikweni pansi pa mkhalidwe womwewo wogwirira ntchito, zomwe zimabweretsa kuchepa kwa mayankho mufiriji. Izi zimachitika makamaka pa compressor zomwe zakhala zikugwiritsidwa ntchito kwa nthawi yayitali. Kuvala kumakhala kwakukulu, kusiyana kofanana kwa gawo lililonse ndi kwakukulu, ndipo ntchito yosindikiza ya valve imachepetsedwa, zomwe zimapangitsa kuti kusamuka kwenikweni kuchepe.

(1) Onani ngati cylinder head paper gasket yasweka ndikuyambitsa kutayikira, ngati kulipo, m'malo mwake.
⑵ Yang'anani ngati ma valve otulutsa mpweya wambiri ndi wotsika sanatsekeredwe mwamphamvu, ndipo m'malo mwake ngati ali.
⑶ Yang'anani pakati pa pisitoni ndi silinda. Ngati chilolezocho ndi chachikulu kwambiri, sinthani.
5.Chizizira pamwamba pa evaporator ndi wandiweyani kwambiri
[Kusanthula zolakwika]Evaporator yozizira yomwe imagwiritsidwa ntchito kwa nthawi yayitali iyenera kusungunuka pafupipafupi. Ngati sichikuphwanyidwa, chisanu chomwe chili paipi ya evaporator chimakula ndikukula. Pamene payipi yonseyo itakulungidwa mu ayezi wowonekera, izi zimakhudza kwambiri kutentha kwa kutentha. Zotsatira zake, kutentha m'nyumba yosungiramo katundu sikugwera mkati mwazofunikira.
[Njira]Siyani kuzizira ndikutsegula chitseko kuti mpweya uziyenda. Mafani angagwiritsidwenso ntchito kufulumizitsa kufalikira kuti muchepetse nthawi yoziziritsa.
6. Pali refrigerating mafuta mu evaporator chitoliro
[Kusanthula zolakwika]Panthawi ya firiji, mafuta ena oziziritsa amakhalabe mupaipi ya evaporator. Pambuyo pakugwiritsa ntchito nthawi yayitali, mafuta akakhala otsalira mu evaporator, amakhudza kwambiri kutentha kwa kutentha ndikupangitsa kuti kuzizire bwino.
【Yankho】Chotsani mafuta a firiji mu evaporator. Chotsani evaporator, phulitsa, ndiyeno iume. Ngati sikophweka kugawanitsa, gwiritsani ntchito kompresa kupopera mpweya kuchokera pakhomo la evaporator, ndiyeno gwiritsani ntchito blowtorch kuti muwumitse.
7. Makina a firiji samatsegulidwa
[Kusanthula zolakwika]Monga momwe firiji imatsukidwa, pakapita nthawi yogwiritsira ntchito, dothi limadziunjikira pang'onopang'ono mu fyuluta, ndipo ma meshes ena amatsekedwa, zomwe zimachepetsa kutuluka kwa refrigerant ndipo zimakhudza kuzizira. Mu dongosolo, valavu yowonjezera ndi fyuluta pa doko loyamwa la compressor imatsekedwa pang'ono.
【Yankho】Magawo otsekereza ang'onoang'ono amatha kuchotsedwa, kutsukidwa, zouma, ndikuyika.
