Kodi mungasankhe bwanji evaporator yoyenera kusungiramo zinthu zozizira?

Chotenthetsera mpweya ndi chinthu chofunikira kwambiri komanso chofunikira kwambiri mu dongosolo la firiji. Popeza ndi chotenthetsera mpweya chomwe chimagwiritsidwa ntchito kwambiri m'malo ozizira, chotenthetsera mpweya chimasankhidwa bwino, zomwe zimakhudza mwachindunji magwiridwe antchito oziziritsira.

Mphamvu ya Evaporator Frosting pa Refrigeration System

Pamene makina oziziritsira a malo osungiramo zinthu zozizira akugwira ntchito bwino, kutentha kwa pamwamba pa evaporator kumakhala kotsika kwambiri kuposa kutentha kwa mame a mpweya, ndipo chinyezi chomwe chili mumlengalenga chidzagwa ndikuundana pakhoma la chubu. Ngati kutentha kwa khoma la chubu kuli kotsika kuposa 0°C, mame adzaundana kukhala chisanu. Kuundana kumachitikanso chifukwa cha kugwira ntchito bwino kwa makina oziziritsira, kotero kuundana pang'ono kumaloledwa pamwamba pa evaporator.

Chifukwa mphamvu ya kutentha kwa chisanu ndi yaying'ono kwambiri, ndi 1 peresenti, kapena 1 peresenti, ya chitsulo, kotero chisanu chimapanga kukana kwakukulu kwa kutentha. Makamaka chisanu chikakhala chokhuthala, chimakhala ngati kusungidwa kwa kutentha, kotero kuti kuzizira mu evaporator sikophweka kutayika, zomwe zimakhudza mphamvu yozizira ya evaporator, ndipo pamapeto pake zimapangitsa kuti malo osungira ozizira asafikire kutentha kofunikira. Nthawi yomweyo, kuzizira kwa refrigerant mu evaporator kuyeneranso kufooka, ndipo refrigerant yosaphwanyika mokwanira ikhoza kuyamwa mu compressor kuti ibweretse ngozi zosonkhanitsa madzi. Chifukwa chake, tiyenera kuyesetsa kuchotsa chisanu, apo ayi chisanu chachiwiri chidzakhala chokhuthala ndipo kuzizira kudzakhala koipa kwambiri.

Monga tonse tikudziwa, kutengera kutentha komwe kumafunika, choziziritsira mpweya chimagwiritsa ntchito ma pitch osiyanasiyana a zipsepse. Choziziritsira mpweya chomwe chimagwiritsidwa ntchito kwambiri mumakampani oziziritsira chimakhala ndi mtunda wa zipsepse wa 4mm, 4.5mm, 6 ~ 8mm, 10mm, 12mm, ndi mtunda wosinthika wa kutsogolo ndi kumbuyo. Mpata wa zipsepse za choziziritsira mpweya ndi wochepa, mtundu uwu wa choziziritsira mpweya ndi woyenera kugwiritsidwa ntchito m'malo otentha kwambiri, kutentha kwa malo ozizira kumakhala kochepa. Mpata wa zipsepse za fan zoziziritsira mpweya umakhala waukulu. Ngati choziziritsira mpweya chosayenerera chasankhidwa, liwiro la zipsepse za frosting ndi lachangu kwambiri, zomwe zidzatseka njira yotulutsira mpweya wa choziziritsira mpweya posachedwa, zomwe zimapangitsa kuti kutentha kwa malo ozizira kuzizire pang'onopang'ono. Njira yochepetsera mpweya ikalephera kugwiritsidwa ntchito mokwanira, pamapeto pake imayambitsa kuti magetsi a makina oziziritsira akuchulukirachulukira.

Momwe mungasankhire mwachangu evaporator yoyenera malo osiyanasiyana ogwiritsira ntchito？

Malo osungiramo zinthu zozizira kwambiri (kutentha kosungira: 0°C~20°C): mwachitsanzo, choziziritsira mpweya m'malo ochitira msonkhano, chosungiramo zinthu zozizira, khonde losungiramo zinthu zozizira, chosungiramo zinthu zatsopano, chosungiramo zinthu zoziziritsira mpweya, chosungiramo zinthu zokhwima, ndi zina zotero, nthawi zambiri amasankha fani yoziziritsira yokhala ndi mtunda wa 4mm-4.5mm

Malo osungiramo zinthu zozizira kutentha kochepa (kutentha kosungira: -16°C--25°C): Mwachitsanzo, malo osungiramo zinthu zoziziritsira kutentha kochepa komanso malo osungiramo zinthu zozizira kutentha kochepa ayenera kusankha mafani ozizira okhala ndi mtunda wa zipsepse wa 6mm-8mm

Nyumba yosungiramo zinthu zoziziritsa mwachangu (kutentha kosungira: -25°C-35°C): nthawi zambiri amasankha fani yoziziritsira yokhala ndi mtunda wa zipsepse wa 10mm ~ 12mm. Ngati malo osungiramo zinthu zoziziritsa mwachangu amafunika chinyezi chambiri, fani yoziziritsira yokhala ndi mtunda wosiyanasiyana wa zipsepse iyenera kusankhidwa, ndipo mtunda wa zipsepse kumbali yolowera mpweya ukhoza kufika 16mm.

Komabe, m'malo ena osungiramo zinthu zozizira okhala ndi zolinga zapadera, mtunda wa zipsepse za fan yoziziritsira sungasankhidwe malinga ndi kutentha komwe kuli m'malo osungiramo zinthu zozizira. Pamwamba pa ℃, chifukwa cha kutentha kwakukulu komwe kumabwera, liwiro lozizira mofulumira, komanso chinyezi chambiri cha katundu, sikoyenera kugwiritsa ntchito fan yoziziritsira yokhala ndi mtunda wa zipsepse wa 4mm kapena 4.5mm, ndipo fan yoziziritsira yokhala ndi mtunda wa zipsepse wa 8mm-10mm iyenera kugwiritsidwa ntchito. Palinso malo osungiramo zinthu zatsopano ofanana ndi omwe amasungiramo zipatso ndi ndiwo zamasamba monga adyo ndi maapulo. Kutentha koyenera kosungirako nthawi zambiri kumakhala -2°C. M'malo osungiramo zinthu zatsopano kapena okhala ndi mpweya wabwino omwe kutentha kosungirako kumakhala kotsika kuposa 0°C, ndikofunikiranso kusankha mtunda wa zipsepse wa osachepera 8mm. Fani yoziziritsira imatha kupewa kutsekeka kwa njira ya mpweya chifukwa cha mphezi yachangu ya fan yoziziritsira komanso kuchuluka kwa mphamvu zomwe zimagwiritsidwa ntchito..
