Kuchaja kozizira kwa makina oziziritsira n'kofunika kwambiri pa ntchito ya makinawo. Kuchaja kosakwanira kumabweretsa kusayenda bwino kwa evaporator, kutsika kwambiri kwa mphamvu yoyamwa ya compressor, kuchepa kwa mphamvu yoziziritsira, komanso kutenthedwa kwambiri kwa compressor. Kuchaja mopitirira muyeso kudzapangitsa kuti mphamvu yotulutsa mpweya ya condenser ikhale yokwera kwambiri, madzi oziziritsira asabwerere m'mbuyo, komanso kuwononga compressor. Makina ambiri ali ndi malire oyenera pa kuchuluka kwa mphamvu yochaja, koma makina ang'onoang'ono ali ndi zofunikira kwambiri pa kuchuluka kwa mphamvu yochaja. Nazi njira zisanu ndi zitatu zodziwika bwino zochaja makina oziziritsira komanso zabwino ndi zovuta zake.
Njira 1: Kudzaza madzi
Masitepe Ogwira Ntchito:
1. Ikani botolo la firiji mozondoka pa sikelo, lumikizani chitoliro chodzaza ndi valavu yodzaza, ndikuchotsa mpweya womwe uli mupaipi.
2. Tsegulani valavu ya botolo la refrigerant ndi valavu yodzaza, ndipo gwiritsani ntchito vacuum ya system kuti muyamwitse refrigerant.
3. Tsekani valavu yotulutsira madzi, yambani compressor, ndipo lolani madziwo alowe mu dongosolo.
4. Yang'anirani kuthamanga kwa makina. Kuthamanga komwe kwatchulidwa kukafika, tsekani valavu yodzaza madzi ndikutsegula valavu yotulutsira madzi.
Zindikirani:
Valavu yoyimitsa yolandirira madzi imagwiritsidwa ntchito pokoka kuti ithandize kuyenda kwa refrigerant mu dongosolo.
Dongosololi liyenera kuchotsedwa pamalo opanda mpweya wambiri likayikidwa koyamba.
Kukwera mofulumira kwa mphamvu ya utsi kumasonyeza kuti condenser ili ndi refrigerant yodzaza ndi mpweya wozizira.
Ubwino ndi kuipa:
Ubwino: Imagwira ntchito m'makina ambiri oziziritsira.
Zoyipa: Kuchuluka kwa kudzaza mufiriji kuyenera kudziwidwa bwino, ndipo kuchuluka kwa kudzaza komwe wopanga amapereka nthawi zambiri kumafunika.
Njira 2: Kudzaza gasi
Masitepe Ogwira Ntchito:
1. Yesani kulemera kwa botolo la firiji.
2. Lumikizani chitoliro cha valavu yoyezera kuthamanga kwa mpweya ku mavavu oyezera mpweya ndi otulutsa mpweya kuti muchotse mpweya womwe uli mupaipi.
3. Tsegulani valavu ya nthunzi ya botolo la firiji, yambani compressor, ndikusintha kuchuluka kwa kudzaza kudzera muyeso wa kupanikizika.
Zindikirani:
Mukamaliza kudzaza, tsekani valavu ya botolo la firiji, yang'anani momwe dongosololi likugwirira ntchito, ndikusankha ngati mupitiliza kudzaza.
Ubwino ndi Kuipa:
Ubwino: Yoyenera makina ang'onoang'ono okhala ndi kudzaza kolondola kwambiri.
Zoyipa: Zoyenera kokha ngati mugwiritsa ntchito mafuta ochepa odzaza mufiriji (nthawi zambiri osapitirira 12kg).
Njira 3: Njira yoyezera
Masitepe Ogwira Ntchito:
Yesani kulemera kwa refrigerant yomwe yawonjezeredwa ku dongosolo mwachindunji.
Zindikirani:
Imagwira ntchito pamene kuchuluka kwa chaji komwe kumafunika pa dongosololi kukudziwika ndipo kukufunika kuchajidwa kwathunthu.
Ngati kuchuluka kwa chaji kuli kochepa, choziziritsira chomwe chili mu dongosolochi chiyenera kutulutsidwa kaye, kenako kubwezeretsedwanso pambuyo pokonza.
Ubwino ndi kuipa:
Ubwino: Yoyenera kugwiritsa ntchito zida zolumikizidwa komanso yosavuta kugwiritsa ntchito.
Zoyipa: Kuchuluka kolondola kwa chaji ya makina kuyenera kudziwidwa pasadakhale.
Njira 4: Njira yamakono
Masitepe Ogwira Ntchito:
1. Ikani ammeter yolumikizira magetsi kumapeto kwa choziziritsira mpweya.
2. Lumikizani botolo la firiji ku doko lodzaza madzi lotsika kuti muchotse mpweya womwe uli mu payipi.
3. Yambitsani compressor, tsegulani valavu ya botolo la refrigerant, yang'anani ammeter, ndipo siyani kuyatsa magetsi akafika pamtengo wovomerezeka.
Zindikirani:
Mphamvu yamagetsi imakhudzidwa ndi zinthu zambiri, monga kusinthasintha kwa magetsi, kutentha kwa malo, ndi zina zotero.
Ubwino ndi kuipa:
Ubwino: Yosavuta kugwiritsa ntchito.
Zoyipa: Mphamvu yamagetsi imasokonezeka mosavuta ndi zinthu zakunja ndipo imakhala yolondola pang'ono.
Njira 5: Njira yowonera pagalasi
Masitepe Ogwira Ntchito:
Yang'anani momwe refrigerant imayendera kudzera mu galasi lowonera lomwe lili mu chitoliro chamadzimadzi. Kuyenda kwa refrigerant yamadzimadzi owonekera bwino kumasonyeza kuti imayikidwa bwino.
Zindikirani:
Ma thovu kapena ma flakes nthawi zambiri amasonyeza kuti firiji siikwanira.
Kutaya mphamvu ya madzi paipi kungayambitsenso thovu, zomwe ziyenera kuphatikizidwa ndi kusanthula momwe dongosolo limagwirira ntchito.
Ubwino ndi kuipa:
Ubwino: wosavuta kuwona komanso wosavuta kumva.
Zoyipa: sitingathe kudalira galasi lowonera kuti liweruze, ndipo njira zina ziyenera kugwiritsidwa ntchito pamodzi.
Njira 6: Njira yokakamiza
Masitepe Ogwira Ntchito:
1. Ikani zoyezera kuthamanga kwa madzi m'magawo okwera komanso otsika ndikulumikiza payipi yodzaza madzi.
2. Yambitsani compressor, yang'anani zizindikiro za ma gauge okwera ndi otsika, ndikuweruza kuchuluka kwa chaji.
Zindikirani:
Kusakwanira kwa mpweya wozizira komanso kuchuluka kwa mpweya wotuluka mumlengalenga kudzakhudza zotsatira za mayeso a kuthamanga kwa mpweya.
Musanayese, ndikofunikira kuonetsetsa kuti mpweya wa dongosolo ukukwaniritsa zofunikira.
Ubwino ndi kuipa:
Ubwino: wolondola kwambiri kudzera mu chiweruzo cha kukakamizidwa.
Zoyipa: chifukwa cha kukhudzidwa kwambiri ndi zinthu zakunja, ndikofunikira kuonetsetsa kuti dongosololi likugwira ntchito bwino.
Njira 7: Kuwerengera njira ya superheat
Masitepe Ogwira Ntchito:
Werengerani kutentha kwakukulu poyesa kutentha kwa suction ndi kuthamanga kwa evaporator suction payipi.
Zindikirani:
Kutentha kwakukulu kwa dongosolo la capillary kumakhudzidwa ndi kupanikizika ndi kukana.
Dongosolo la ma valve okulitsa limakonda kudzaza kwambiri, ndipo kutentha kwakukulu kuyenera kulamulidwa pa madigiri 58.℃.
Ubwino ndi kuipa:
Ubwino: Imagwiritsidwa ntchito pamakina okulitsa ma valavu okhala ndi kulondola kwakukulu.
Zoyipa: Ntchito yovuta ndipo imafuna kuyeza kolondola.
Njira 8: Njira yoyezera mulingo wamadzimadzi
Masitepe Ogwira Ntchito:
Tsegulani doko loyesera mulingo wamadzimadzi la cholandirira madzi kuti muwone ngati pali madzi oziziritsira omwe akutuluka.
Zindikirani:
Zipangizo zazikulu zolandirira madzi zitha kukhala ndi zizindikiro zoyandama kuti zithandize kuwona kuchuluka kwa madzi.
Ubwino ndi kuipa:
Ubwino: Yachilengedwe komanso yosavuta kuweruza kuchuluka kwa zodzaza.
Zoyipa: Imagwira ntchito kokha pamakina omwe ali ndi madoko oyesera mulingo wamadzimadzi.
Chidule:
Njira iliyonse yodzazira ili ndi zochitika zake, ubwino ndi kuipa kwake. Kusankha njira yoyenera kumafuna kuganizira mozama za mtundu wa makina, zofunikira pa kuchuluka kwa kudzaza ndi momwe amagwirira ntchito. Pa makina ang'onoang'ono, njira zodzazira ndi zoyezera mpweya zimagwiritsidwa ntchito kwambiri; pomwe pamakina akuluakulu, njira zodzazira madzi ndi kupanikizika zimagwiritsidwa ntchito kwambiri. Mosasamala kanthu za njira yomwe ikugwiritsidwa ntchito, magwiridwe antchito a makina ayenera kuyang'aniridwa mosamala kuti atsimikizire kuti kuchuluka kwa kudzaza ndi kolondola komanso kupewa kuwonongeka kwa makinawo.
