1. Kutuluka kwa refrigerant
[Kusanthula Zolakwika]Pambuyo poti refrigerant yatuluka mu dongosolo, mphamvu yoziziritsira imakhala yocheperako, mphamvu yokoka ndi kutulutsa mpweya imakhala yochepa, ndipo valavu yowonjezera imatha kumva phokoso la mpweya lomveka bwino kwambiri kuposa nthawi zonse. Evaporator ilibe chisanu kapena chisanu choyandama pang'ono. Ngati dzenje la valavu yowonjezera lakulitsidwa, mphamvu yokoka mpweya sidzasintha kwambiri. Pambuyo pozimitsa, mphamvu yofanana mu dongosolo nthawi zambiri imakhala yotsika kuposa mphamvu yokwanira yofanana ndi kutentha komweko.
[Yankho]Mufiriji ikatuluka madzi, simuyenera kufulumira kudzaza makinawo ndi refrigerant. M'malo mwake, muyenera kupeza malo otayikira madzi nthawi yomweyo ndikudzazanso refrigerant mukamaliza kukonza.
2. Mumalipira firiji yambiri mukamaliza kukonza
[Kusanthula zolakwika]Kuchuluka kwa chotenthetsera chomwe chimayikidwa mu makina oziziritsira pambuyo pokonza kumaposa mphamvu ya makinawo, chotenthetseracho chimakhala ndi voliyumu inayake ya chotenthetsera, kuchepetsa malo otenthetsera kutentha, ndikuchepetsa mphamvu yozizira, ndipo mphamvu zokoka ndi kutulutsa mpweya nthawi zambiri zimakhala zapamwamba. Pa mphamvu yachibadwa, chotenthetseracho sichimazizira, ndipo kutentha m'nyumba yosungiramo zinthu kumachepa.
[Yankho]Malinga ndi njira yogwirira ntchito, firiji yochulukirapo iyenera kutulutsidwa pa valavu yodulira mpweya wothamanga kwambiri patatha mphindi zochepa kutsekedwa, ndipo mpweya wotsala mu dongosololi ukhozanso kutulutsidwa panthawiyi.
3. Pali mpweya mu makina oziziritsira
[Kusanthula zolakwika]Mpweya womwe uli mu makina oziziritsira mpweya umachepetsa mphamvu ya makina oziziritsira mpweya. Chodabwitsa kwambiri ndichakuti mphamvu yoyamwa ndi kutulutsa mpweya imakwera (koma mphamvu yotulutsa mpweya siinapitirire mtengo wovomerezeka), ndipo kutentha kuchokera ku malo otulutsira mpweya wa compressor kupita ku malo olowera mpweya wa condenser kumawonjezeka kwambiri. Chifukwa cha mpweya womwe uli mu makinawo, mphamvu yotulutsa mpweya ndi kutentha kwa mpweya zimawonjezeka.
[Yankho]Mukhoza kutulutsa mpweya kuchokera ku valavu yozimitsa mpweya yothamanga kwambiri kangapo mumphindi zochepa mutazimitsa, ndipo mutha kudzazanso firiji moyenera malinga ndi momwe zinthu zilili.
4. Kugwiritsa ntchito bwino kwa compressor pang'ono
[Kusanthula Zolakwika]Kugwira ntchito kochepa kwa compressor yoziziritsa kumatanthauza kuchepa kwa kusuntha kwenikweni pansi pa mkhalidwe womwewo wogwirira ntchito, zomwe zimapangitsa kuti mphamvu yoziziritsa ichepetse. Izi zimachitika makamaka pa ma compressor omwe akhala akugwiritsidwa ntchito kwa nthawi yayitali. Kuwonongeka kwake ndi kwakukulu, kusiyana kofanana kwa gawo lililonse ndi kwakukulu, ndipo magwiridwe antchito otseka a valavu amachepa, zomwe zimapangitsa kuti kusuntha kwenikweni kuchepe.

(1) Yang'anani ngati gasket ya pepala la silinda yawonongeka ndipo yayambitsa kutuluka kwa madzi, ngati ilipo, isintheni.
⑵ Yang'anani ngati ma valve otulutsa mpweya okhala ndi mphamvu yamphamvu komanso yotsika sanatsekedwe bwino, ndipo asintheni ngati ali otsekedwa bwino.
⑶ Yang'anani malo otseguka pakati pa pistoni ndi silinda. Ngati malo otseguka ndi akulu kwambiri, asintheni.
5. Chipale chofewa pamwamba pa evaporator ndi chokhuthala kwambiri
[Kusanthula zolakwika]Chotenthetsera chosungiramo zinthu zozizira chomwe chagwiritsidwa ntchito kwa nthawi yayitali chiyenera kusungunuka nthawi zonse. Ngati sichisungunuka, chisanu chomwe chili pa payipi ya chotenthetsera chidzakhala chokhuthala kwambiri. Pamene payipi yonse yakulungidwa mu ayezi wowonekera bwino, zidzakhudza kwambiri kusamutsa kutentha. Chifukwa chake, kutentha komwe kuli m'nyumba yosungiramo zinthu sikugwera mkati mwa mulingo wofunikira.
[Yankho]Siyani kusungunula chisanu ndipo tsegulani chitseko kuti mpweya uziyenda bwino. Mafani angagwiritsidwenso ntchito kufulumizitsa kufalikira kwa madzi kuti achepetse nthawi yosungunula chisanu.
6. Mu chitoliro cha evaporator muli mafuta ophikira mufiriji
[Kusanthula zolakwika]Pa nthawi yoziziritsa, mafuta ena osungiramo mafuta amakhalabe mu evaporator payipi. Pambuyo pa nthawi yayitali yogwiritsidwa ntchito, ngati pali mafuta otsala mu evaporator, izi zimakhudza kwambiri momwe kutentha kumayendera komanso zimapangitsa kuti kuziziritsa kusakhale bwino.
【Yankho】Chotsani mafuta ophikira mu evaporator. Chotsani evaporator, ipumuleni, kenako iume. Ngati sikophweka kuichotsa, gwiritsani ntchito compressor kuti mupope mpweya kuchokera pakhomo la evaporator, kenako gwiritsani ntchito blowtorch kuti muume.
7. Makina oziziritsira satsegulidwa
[Kusanthula zolakwika]Popeza makina oziziritsira sakutsukidwa, pambuyo pa nthawi inayake yogwiritsidwa ntchito, dothi limasonkhana pang'onopang'ono mu fyuluta, ndipo ma meshes ena amatsekedwa, zomwe zimachepetsa kuyenda kwa refrigerant ndikukhudza kuzizira. Mu makinawo, valavu yokulitsa ndi fyuluta yomwe ili pa doko loyamwa la compressor nazonso zimatsekedwa pang'ono.
【Yankho】Zigawo zotchingira zazing'ono zimatha kuchotsedwa, kutsukidwa, kuumitsidwa, kenako nkuyikidwa.
