Njira zogwirira ntchito zotsegulira mafakitale otentha a freon system

1. Njira zotsegulira poyendetsa mafakitale a dongosolo la Freon

1. Tsekani valavu yotulutsa ya accumulator kapena valavu yotulutsa ya condenser;

2. Yambitsani kompresa ndi kusonkhanitsa firiji m’chigawo chotsikirapo mu condenser kapena accumulator;

3. Makina otsika akapanikizika amatsikira kumalo opanda zingwe, makina amasiya;

4. Tulutsani pulagi yolumikizira pa bowo lolowera utsi wotseka ndikutembenuza pafupifupi theka. Letsani kutuluka kwa mpweya ndi chikhatho cha dzanja lanu. Dzanja likamva mpweya wozizira komanso wothira mafuta m’manja mwanu, zikutanthauza kuti mpweya watopa. Limbikitsani pulagi, bweretsani tsinde la utsi, ndikutseka dzenje lolambalalitsira.

5. Tiyenera kudziwa kuti nthawi ya deflation iliyonse siyenera kukhala yayitali kwambiri, ndipo imatha kuchitika mosalekeza kwa nthawi ziwiri kapena zitatu kupewa kuwononga firiji. Ngati pali chotsekera chotsekera pamwamba pa condenser kapena cholembera, mpweya amathanso kutulutsidwa kuchokera ku valavu.

2. Njira zogwiritsira ntchito mafakitale otentha a mafiriji

1. Mukamagwiritsa ntchito olekanitsa mpweya kuti mutulutse mpweya, ikani valavu yobwerera yolekanitsa mpweya pamalo otseguka kuti muchepetse kupsinjika kwa cholekanitsa mpweya ndikutsitsimula, ndipo mavavu ena onse ayenera kutsekedwa.

2. Tsegulani bwino valavu yosakanikirana ndi mpweya kuti mpweya wosakanikirana ndiwo uzizilitsa.

3. Tsegulani pang’ono valavu yamagetsi kuti mupukuse firiji mu olekanitsa mpweya kuti ayambitse ndi kuyamwa kutentha kuti kuziziritsa gasi wosakanikirana.

4. Lumikizani payipi ya labala yomwe imagwiritsidwa ntchito polumikizira valavu kuti malekezero amadzi amalowetsedwa m’madzi mumtsuko wamadzi. Refrigerant yomwe ili mu mpweya wosakanizika itakhazikika m’madzi a ammonia, chisanu chimayamba pansi pa olekanitsa mpweya. Pakadali pano, valavu yamlengalenga imatha kutsegulidwa pang’ono kuti izitulutsa mpweya kudzera pachidebe chamadzi. Ngati thovu likuzungulira likamatuluka m’madzi, ndipo palibe kusintha kwa voliyumu, madziwo sagwedezeka ndipo kutentha sikukwera, ndiye kuti mpweya umatuluka. Pakadali pano, kutsegula kwa valavu yotulutsa mpweya kuyenera kukhala koyenera.

5. Firiji yomwe ili mu mpweya wosakanizika imangoloŵetsedwera pang’ono m’madzi osungunuka ndikuwunjikira pansi. Madzi amadzimadzi amatha kuwonekera kuchokera pachimake pachikopa. Madziwo akafika pa 12, tsekani ma valavu opumira amadzimadzi ndikutsegula valavu yamadzi yobwerera. Madzi otsika a refrigerant amabwezedwa kupatula olekanitsa mpweya kuti aziziritsa mpweya wosakanikirana. Pamene chisanu chapansi pa chisanu chatsala pang’ono kusungunuka, tsekani valavu yam’madzi yobwerera ndiyeno mutsegule valavu yamadzi.

6. Mukamaletsa kutuluka kwa mpweya, choyamba tsekani valavu yotulutsa mpweya kuti firiji isatuluke, kenako tsekani valavu yamadzi yopumira ndi valavu yosakanikirana ya gasi. Pofuna kupewa kukakamizidwa kwa chipangizo chotulutsa mpweya kuti chisakule, valavu yobwerera siyenera kutsekedwa.
