Kodi Mungadziwe Bwanji Ndi Kupeza Malo Enieni Otayikira Mkati mwa Firiji?

Kodi mungakonze bwanji payipi yotuluka madzi mufiriji?

Ma evaporator a mafiriji awa nthawi zambiri amapangidwa ndi zinthu zopanda mkuwa, ndipo bowa amaonekera pakatha nthawi yayitali akugwiritsidwa ntchito. Mukayang'ana mbali za mapaipi zomwe zikutuluka, njira yokhazikika yokonzera ndikusintha mbali za mapaipi zomwe zawonongeka ndi zatsopano. Ndiye mungayang'ane bwanji malo omwe kutayikira kwa refrigerant mufiriji ntchito yokonzanso ziwalo zina isanayambe?

 Kodi mungaweruze bwanji kutayikira kwa firiji mufiriji?

Ngati firiji yoyima bwino siikuzizira, mukayatsa makina kwa mphindi zambiri, gwirani chitoliro champhamvu ndipo mumve kutentha; nthawi yomweyo, chitoliro champhamvu kwambiri chimakhala pafupi ndi kutentha kwa chipinda (nthawi zambiri chiyenera kukhala pafupifupi 0°C, ndi chisanu pang'ono), chomwe chingaganizidwe ngati cholakwika cha firiji. Refrigerant imatuluka.

 Kodi mungatanthauze bwanji kuchuluka kwa kutayikira kwa madzi?

Kawirikawiri, kutayikira kwa mafiriji mufiriji kumachitika m'zinthu izi: evaporator yayikulu, evaporator yothandizira, chubu chotenthetsera chimango cha chitseko, condenser yomangidwa mkati ndi malo ena.

 

 Kodi mungayese bwanji mapaipi okhala ndi mpweya wopanikizika?

 

Njira yosadalirika yowunikira ngati pali kutayikira kwa madzi:

Mainjiniya osadziwa zambiri okonza zinthu amalumikiza mwachindunji choyezera kuthamanga kwa mpweya ku chitoliro cha compressor, kuwonjezera mpweya wouma ku 0.68MPa, ndikuyesa kuthamanga kwa chitoliro chakunja cha firiji. Njira iyi nthawi zina imakhala yopanda phindu, chifukwa compressor, condenser, evaporator ndi zida zina zapaipi zimalumikizidwa pamodzi, mapaipi amalumikizana, ndipo mphamvu ya mpweya ndi yayikulu. Kwinakwake mu chitoliro, mtengo wowonetsera pointer wa choyezera kuthamanga kwa mpweya sudzatsika pakapita nthawi yochepa, ngakhale kwa masiku opitilira khumi. Chifukwa chake, njira iyi siyodalirika popezera kutuluka kwa madzi.

 

Njira yodalirika yodziwira:

1. Choyamba yang'anani ngati payipi yowonekera ikutuluka; (payipi yowonekera ikhoza kufufuzidwa ngati ikutuluka ndi thovu la sopo)

2. Ngati palibe kutuluka kwa madzi mu chitoliro chowonekera, ndi nthawi yoti muluke mu choyezera kuthamanga kuti muwone momwe chitoliro chamkati chilili.

3. Kulukana choyezera kuthamanga kwa mpweya pa chitoliro chotsika mphamvu (Φ6mm, chomwe chimatchedwanso chitoliro cholowera mpweya) ndi chitoliro chotulutsa mpweya champhamvu (Φ5mm) pafupi ndi compressor;

4. Dulani capillary patali ndi 5mm kuchokera pa fyuluta, ndipo lumikizani malekezero a capillary yodulidwayo ndi solder;

5. Onjezani mpweya wouma kuchokera mu chubu chopangira cha compressor kufika pa mphamvu ya 0.68MPa, kenako tsekani chubu chopangira kuti mpweya wamkati ukhalebe ndi mphamvu;

6. Yembekezerani kuti kutentha kwa malo onse olumikizirana kukhale kofanana ndi kutentha kwa malo ozungulira (kwa ola limodzi), kenako gwiritsani ntchito cholembera kuti mulembe malo a singano yoyezera pa chivundikiro chagalasi chowonekera bwino cha choyezera kuthamanga;

7. Pitirizani kuyang'anira kwa masiku awiri kapena atatu (mkhalidwe wake ndi wakuti kutentha kwa malo ozungulira sikusintha kwambiri, apo ayi kudzakhudza mtengo wa mpweya mkati mwa payipi);

8. Pa nthawi yoyang'anira, ngati chizindikiro cha chimodzi mwa zizindikiro za kuthamanga kwa magazi chatsika, chonde lembani chizindikirocho pachikuto chowonekera cha dial;

9. Pambuyo popitiriza kuyang'anitsitsa kwa masiku awiri kapena atatu, kuthamanga kwa mpweya kumatsika kwambiri, zomwe zimatsimikizira kuti payipi yolumikizidwa ku gauge ya mpweya yatuluka.

 

Unikani padera malinga ndi kutuluka kwa condenser ndi kutuluka kwa evaporator:

 

a)   Ngati mtengo wa pressure gauge mu evaporator part watsika, uyenera kuunikidwanso m'magawo.

Chongani gawo la evaporator ndi gawo:

Chotsani mbale yakumbuyo, lekanitsani ma evaporator apamwamba ndi otsika, ikani choyezera kuthamanga, ndipo pitirizani kuwonjezera mayeso a kuthamanga kwa mpweya mpaka gawo lenileni la gawo la evaporator lomwe lili ndi mipata litapezeka.

 

b)  Ngati ndi kutsika kwa mphamvu ya gawo la condenser, chifukwa chake chiyenera kudziwika malinga ndi kapangidwe kake.

Ngati ndi chonchochoziziritsira chokhala ndi kapangidwe kokhazikika kumbuyo, chomwe chingayambitse kwambiri ndi kubowoka kwa chitoliro cha mame pa chimango cha chitseko.

Ngati ndi chonchochoziziritsira chomangidwa mkati, ndikofunikira kuyesanso kusintha kwa mphamvu ya kuthamanga kwa magazi m'magawo, ndikuyika chiyerekezo chatsopano cha kuthamanga kwa magazi mu payipi kuti muchite izi.
