Kodi chotenthetsera cha defroster chimagwira ntchito bwanji?

Zotenthetsera zosungunulirandi zinthu zofunika kwambiri mu makina oziziritsira, makamaka mu mafiriji ndi mafiriji, komwe ntchito yawo ndikuletsa kuzizira kwa ma evaporator coils. Kuchulukana kwa zigawo za chisanu kungachepetse kwambiri magwiridwe antchito a makinawa, zomwe pamapeto pake zimakhudza mphamvu yawo yozizira.

Thechubu chotenthetsera cha firijindi gawo lofunika kwambiri la makina oziziritsira firiji, omwe amagwiritsidwa ntchito makamaka kusungunula chisanu chomwe chimasonkhanitsidwa pa evaporator mu nthawi yozizira yokha kuti zitsimikizire kuti firiji ikugwira ntchito bwino.

Ntchito yotenthetsera madzi:

 Kusungunula: Pa nthawi yogwira ntchito mufiriji, pamwamba pa evaporator padzakhala chisanu, ndipo chisanu chokhuthala kwambiri chidzakhudza momwe firiji imagwirira ntchito.chubu chotenthetsera madzi chosungunulaimasungunula chisanu potenthetsa, kotero kuti evaporator ikhoza kubwerera ku momwe imagwirira ntchito.

 Chipale chozizira chokha: Mafiriji amakono nthawi zambiri amakhala ndi makina ozizirira okha omwesungunulani chubu chotenthetseraIdzayamba pa nthawi yoikika kapena pansi pa mkhalidwe woikika ndipo idzazimitsa yokha ikasungunuka.

Mfundo yogwira ntchito ya chotenthetsera chosungunula madzi ndi kutentha chotenthetsera cha evaporator nthawi zina kuti chisungunuke chisanu chilichonse chomwe chasonkhanitsidwa. Zotenthetsera zosungunula madzi zomwe zimagwiritsidwa ntchito nthawi zambiri zimagawidwa m'mitundu iwiri: mtundu wa kutentha kwamagetsi ndi mtundu wa kutentha kwa mpweya wotentha.

Zotenthetsera zamagetsi zimasungunula chisanuKawirikawiri amaikidwa m'mafiriji ndi m'mafiriji apakhomo. Zotenthetsera zimenezi zimapangidwa ndi zinthu zotsutsana monga nickel-chromium alloys, zomwe zimakhala ndi kukana kwakukulu ndipo zimatha kupanga kutentha pamene mphamvu yamagetsi imadutsa mwa izo. Zimayikidwa mwanzeru pafupi ndi ma evaporator coils kapena zimayikidwa mwachindunji pa ma coils.

Firiji ikayamba kugwira ntchito mufiriji, ma evaporator coils amayamwa kutentha kuchokera mkati, zomwe zimapangitsa kuti chinyezi mumlengalenga chizizizira ndikuzizira pa ma coils. Pakapita nthawi, izi zimapangitsa kuti chisanu chizizizira kwambiri. Pofuna kupewa kuchulukana kwa chisanu, choyezera nthawi yothira madzi kapena bolodi lowongolera nthawi ndi nthawi limayambitsa chisanu, nthawi zambiri maola 6 mpaka 12 aliwonse, kutengera chitsanzo cha firiji.

Pamene njira yosungunula madzi iyamba, makina owongolera amadula compressor ndikuyambitsachotenthetsera chosungunulaMphamvu yamagetsi imadutsa mu chotenthetsera, ndikupanga kutentha kuti kutenthetse ma evaporator coils. Pamene kutentha kwa coil kukukwera, chisanu chosonkhanitsidwacho chimayamba kusungunuka ndikusintha kukhala madontho a madzi.

Pofuna kupewa kuwonongeka kwa makina ndikuwonetsetsa kuti akusungunuka bwino, thermostat yosungunula madzi imayang'anira kutentha kwa evaporator coil. Kutentha kukafika pamlingo winawake, zomwe zikusonyeza kuti chisanu chasungunuka kwathunthu, thermostat imatumiza chizindikiro ku makina owongolera kuti ayimitse kuzungulira kwa kusungunuka kwa madzi.

Madzi opangidwa kuchokera ku chisanu chosungunuka amatsikira pansi pa evaporator coil kupita ku drip pan yomwe ili pansi pa chipangizocho. Kumeneko, nthawi zambiri amasanduka nthunzi chifukwa cha kutentha komwe kumapangidwa ndi compressor panthawi yoziziritsa nthawi zonse.

Kumbali ina, makina osungunula mpweya wotentha amapezeka kwambiri m'zida zazikulu zosungiramo zinthu zozizira. M'makina awa, m'malo mogwiritsa ntchito zotenthetsera zamagetsi, firiji yokha imagwiritsidwa ntchito kusungunula ma coil. Panthawi yosungunula, makina osungunula mpweya amasintha njira yake yogwirira ntchito.

Vavu imalowetsa mwachindunji mpweya wozizira komanso wotentha kwambiri womwe umatuluka mu compressor kupita ku evaporator coil. Mpweya wotentha ukadutsa mu coil, umasamutsa kutentha kupita ku chisanu, zomwe zimapangitsa kuti usungunuke. Madzi osungunuka amachotsedwa. Pambuyo poti kusungunuka kwa madzi kutha, valavu imabwezeretsa refrigerant ku cooling circuit yake yanthawi zonse.

Kaya ndi makina osungunula amagetsi kapena makina osungunula mpweya wotentha, cholinga chawo ndikuchotsa chisanu pa coil ya evaporator, koma amagwiritsa ntchito njira zosiyanasiyana zosungunula.

Kusamalira nthawi zonse ndi kugwira ntchito bwino kwamachubu otenthetsera madzi oundanandizofunikira kwambiri pakugwira ntchito bwino kwa makina oziziritsira. Kulephera kugwira ntchito bwino kwa chotenthetsera kungayambitse kuzizira kwambiri, kuchepa kwa magwiridwe antchito a firiji, komanso kuwonongeka kwa zida.

Ma heater osungunula mpweya amathandiza kwambiri kuti makina oziziritsira mpweya azigwira ntchito bwino poletsa chisanu kuti chisapangike pa ma evaporator coils. Kaya kudzera mu kutentha kolimba kapena kutentha kwa mpweya wotentha, ma heater amenewa amaonetsetsa kuti ma coilswo sazizira, zomwe zimathandiza kuti makinawo azigwira ntchito bwino komanso kuti kutentha komwe kumafunika mkati mwa chipangizocho kukhale koyenera.
