Kodi chotenthetsera cha defroster chimagwira ntchito bwanji?

Defrosting heatersndi zigawo zikuluzikulu mu kachitidwe firiji, makamaka mu mufiriji ndi mafiriji, kumene udindo wawo ndi kupewa chisanu pa evaporator koyilo. Kuchulukana kwa zigawo za chisanu kumatha kuchepetsa kwambiri magwiridwe antchito a machitidwewa, pamapeto pake kumakhudza kuzizira kwawo.

Thefiriji defrosting Kutentha chubundi mbali yofunika ya firiji dongosolo firiji, amene makamaka ntchito kusungunula chisanu wosanjikiza anasonkhanitsa pa evaporator mu makina chisanu mkombero kuonetsetsa firiji dzuwa la firiji.

Ntchito ya Defrost heater:

 Defrosting: Panthawi yogwira ntchito ya firiji, pamwamba pa evaporator adzakhala chisanu, ndipo chisanu chakuda kwambiri chidzakhudza zotsatira za firiji. Thedefrost heater chubuamasungunula chisanu wosanjikiza ndi kutentha, kuti evaporator kubwerera mwakale kugwira ntchito.

 Chichisanu chokha: Mafiriji amakono nthawi zambiri amakhala ndi makina opangira chisanu momwedefrost Kutentha chubuidzayamba pa nthawi yoikika kapena pansi pa chikhalidwe chokhazikitsidwa ndikuzimitsa yokha pambuyo pa defrosting.

Mfundo yogwirira ntchito ya chotenthetsera cha defrost ndikutenthetsa koyilo ya evaporator pakapita nthawi kuti asungunuke chisanu chilichonse chomwe chawunjikana. Zotenthetsera zomwe zimagwiritsidwa ntchito nthawi zambiri zimagwera m'mitundu iwiri: mtundu wamagetsi otenthetsera ndi mtundu wotentha wa gasi.

Magetsi oziziritsira magetsiamaikidwa m'mafiriji apanyumba ndi mafiriji. Zotenthetserazi zimapangidwa ndi zinthu zokana monga ma aloyi a nickel-chromium, omwe amatha kukana kwambiri ndipo amatha kutulutsa kutentha akamadutsa. Amayikidwa mwanzeru pafupi ndi ma evaporator coils kapena amaikidwa mwachindunji pa ma koyilo.

Pamene firiji ikugwira ntchito mufiriji, zozungulira za evaporator zimatenga kutentha kuchokera mkati, zomwe zimapangitsa kuti chinyontho cha mumlengalenga chifanane ndi kuzizira pazitsulozo. Pakapita nthawi, izi zimapanga chisanu. Pofuna kupewa kuchulukira kwa chisanu, chowongolera nthawi ndi nthawi kapena bolodi yowongolera nthawi ndi nthawi imayambitsa kuzungulira kwa chisanu, nthawi zambiri maola 6 mpaka 12 aliwonse, kutengera chitsanzo cha firiji.

Kuzungulira kwa defrost kukayamba, makina owongolera amadula kompresa ndikuyambitsadefrost heater. Yapano imadutsa mu chotenthetsera, kutulutsa kutentha kuti itenthetse ma coil a evaporator. Pamene kutentha kwa koyilo kumakwera, chisanu chochuluka chimayamba kusungunuka ndikusanduka madontho amadzi.

Kuti mupewe kuwonongeka kwa dongosolo ndikuwonetsetsa kusungunuka bwino, thermostat ya defrost imayang'anira kutentha kwa koyilo ya evaporator. Kutentha kukafika pamlingo wina, kusonyeza kuti chisanu chasungunuka kwathunthu, thermostat imatumiza chizindikiro ku dongosolo lowongolera kuti liyimitse kuzungulira kwa chisanu.

Madzi opangidwa kuchokera ku chisanu chosungunuka amayenda pansi pa chokokera cha evaporator kupita ku poto yodontha yomwe ili pansi pa chipangizocho. Kumeneko, nthawi zambiri amasanduka nthunzi chifukwa cha kutentha kopangidwa ndi kompresa panthawi ya firiji.

Kumbali inayi, makina otenthetsera mpweya wotentha amakhala ofala kwambiri pazida zazikulu zafiriji zamalonda. M'makinawa, m'malo mogwiritsa ntchito chotenthetsera chamagetsi, firiji yokha imagwiritsidwa ntchito kuti isungunuke. Panthawi ya defrosting, firiji imasintha njira yake yogwiritsira ntchito.

Vavu imayambitsa mpweya wotentha kwambiri komanso wothamanga kwambiri wotuluka mu kompresa kupita ku koyilo ya evaporator. Pamene mpweya wotentha umayenda mu koyilo, umatulutsa kutentha ku chisanu, ndikupangitsa kuti isungunuke. Madzi osungunuka amachotsedwa. Pambuyo pakutha kwa defrosting, valavu imawongoleranso refrigerant kudera lake lozizira nthawi zonse.

Kaya ndi makina osungunula magetsi kapena mpweya wotentha wa gasi, cholinga chawo ndi kuchotsa chisanu pa koyilo ya evaporator, koma amagwiritsa ntchito njira zosiyanasiyana zochepetsera madzi.

Wokhazikika yokonza ndi ntchito yachibadwa yadefrost heater machubundizofunika kuti firiji igwire bwino ntchito. Kulephera kugwira ntchito kwa chotenthetsera kungayambitse chisanu chochuluka, kuchepetsa mphamvu ya firiji, ndi kuwonongeka kwa zipangizo.

Zotenthetsera zoziziritsa kukhosi zimagwira ntchito yofunika kwambiri kuti firiji isagwire bwino ntchito poletsa kuti chisanu chisapangike pamakoyilo a evaporator. Kaya kudzera mu kukana kutenthetsa kapena kutentha kwa gasi, zotenthetserazi zimaonetsetsa kuti ma koyilo sazizira kwambiri, zomwe zimapangitsa kuti makinawo azigwira ntchito bwino komanso kusunga kutentha komwe kumafunikira mkati mwa chipangizocho.
