N'chifukwa chiyani evaporator ozizira yosungirako kuzizira?

Kuzizira kwa evaporator ya firiji yozizira kuyenera kufufuzidwa mozama kuchokera kuzinthu zambiri, ndipo mapangidwe a evaporator, kusiyana kwa ma evaporator, masanjidwe a chitoliro, ndi zina zotero. Zifukwa zazikulu za kuzizira kwambiri kwa chozizira chosungira mpweya ndi izi:

1. Mapangidwe okonzekera, wosanjikiza wotchinga mpweya wotsimikizira chinyezi, ndi wosanjikiza wotenthetsera kutentha amawonongeka, zomwe zimapangitsa kuti mpweya wambiri wakunja ulowe m'malo ozizira;

2. Chitseko chosungirako chozizira sichimasindikizidwa mwamphamvu, chitseko cha chitseko kapena chitseko chimakhala chopunduka, ndipo mzere wosindikizira ndi wokalamba ndipo umataya kusungunuka kapena kuwonongeka;

3. Kuchuluka kwa zinthu zatsopano zalowa m'malo ozizira;

4. Kusungirako kozizira kumawonekera kwambiri pakugwira ntchito kwa madzi;

5. Kulowa pafupipafupi ndi kutuluka kwa katundu;
Njira zinayi zodziwika bwino zochepetsera ma evaporators ozizira:

Choyamba: kupukuta pamanja

Pa ndondomeko ya defrosting pamanja, chitetezo ndicho choyamba, ndipo musawononge zipangizo za firiji. Ambiri mwa chisanu chokhazikika pazida amagwera pazida za firiji mu mawonekedwe olimba, omwe alibe zotsatira zochepa pa kutentha mkati mwa malo ozizira. Zoyipa zake ndi kuchuluka kwa anthu ogwira ntchito, kukwera mtengo kwa nthawi yogwira ntchito, kutsekereza kosakwanira kwa kupukutira pamanja, kupukutira kosakwanira, komanso kuwonongeka kosavuta kwa zida zopangira firiji.

Chachiwiri: chisanu chosungunuka m'madzi

Monga momwe dzinalo likusonyezera, ndikutsanulira madzi pamwamba pa evaporator, kuonjezera kutentha kwa evaporator, ndi kukakamiza chisanu chokhazikika pamwamba pa evaporator kuti chisungunuke. Madzi sungunuka chisanu ikuchitika kunja kwa evaporator, choncho m`kati madzi sungunuka chisanu, m`pofunika kuchita ntchito yabwino ya madzi otaya processing kuti asakhudze ntchito yachibadwa ya zipangizo firiji ndi zinthu zina anaika mu ozizira yosungirako.

Kutsekemera kwa madzi ndikosavuta kugwira ntchito ndipo kumatenga nthawi yochepa, yomwe ndi njira yabwino kwambiri yochepetsera madzi. M'malo ozizira ozizira ndi kutentha kochepa kwambiri, mutatha kubwereza mobwerezabwereza, ngati kutentha kwa madzi kuli kochepa kwambiri, kudzakhudza zotsatira zowonongeka; Ngati chisanu sichikutsukidwa mkati mwa nthawi yoikika, chisanu chikhoza kusandulika kukhala madzi oundana pamene choziziritsa mpweya chimagwira ntchito bwino, zomwe zimapangitsa kuti chisanu chikhale chovuta kwambiri.

Mtundu wachitatu: Kutentha kwamagetsi kwamagetsi

Kutentha kwamagetsi kwamagetsi ndi kwa zida zomwe zimagwiritsa ntchito mafani posungira mufiriji posungirako kuzizira. Machubu otenthetsera magetsi kapena mawaya otenthetsera amayikidwa mkati mwa zipsepse za firiji molingana ndi mawonekedwe apamwamba, apakati ndi apansi, ndipo faniyo imachotsedwa chifukwa cha kutentha kwapano. Njirayi imatha kuwongolera mwanzeru kuzizira kudzera pa chowongolera cha microcomputer. Pokhazikitsa magawo a defrost, defrost yanzeru yanthawi yake imatha kukwaniritsidwa, yomwe ingachepetse kwambiri nthawi yantchito ndi mphamvu. Choyipa ndichakuti kutentha kwamagetsi kumawonjezera kugwiritsa ntchito mphamvu zosungirako kuzizira, koma kuchita bwino ndikwambiri.

Mtundu wachinayi: defrost yotentha yogwira ntchito:

Hot working sing'anga defrost ndi ntchito superheated refrigerant nthunzi ndi apamwamba kutentha kutayidwa ndi kompresa, amene amalowa evaporator pambuyo kudutsa olekanitsa mafuta, ndi kwa kanthawi akuchitira evaporator monga condenser. Kutentha kumasulidwa pamene yotentha ntchito sing'anga condenses ntchito kusungunula chisanu wosanjikiza pamwamba pa evaporator. Pa nthawi yomweyo, refrigerant ndi mafuta mafuta poyamba anaunjikira evaporator ndi kutayidwa mu defrost kumaliseche mbiya kapena otsika-anzanu kufalitsidwa mbiya pogwiritsa ntchito otentha sing'anga pressurization kapena yokoka. Pamene mpweya wotentha umasungunuka, katundu wa condenser amachepetsedwa, ndipo kugwira ntchito kwa condenser kungathenso kupulumutsa magetsi.
