Njira Zosayenera ndi Zosasamala za Zida Zozizira.

Pamene kutentha kwanyengo kwa firiji yosungirako ndi kotsika kuposa 0 ° C, kusanjikiza chisanu kumawonekera padziko lonse lapansi, kumakhudza kutentha kwake. Chifukwa chake, defrosting pafupipafupi ndi gawo lofunikira kwambiri pakukonza kozizira. Pali njira zambiri zokondera. Pakadali pano, opanga opanga ozizira amagwiritsa ntchito njira zisanu: Kuchotsa zojambula zazikulu, kuchepa kwamagetsi, mpweya wowotcha, kutuluka kwamadzi, madzi otentha a mpweya.

1. Kutanthauzira kwa buku ndiko kuchotsa pamanja pa chisanu pamtunda wa chubu cholerera. Njira iyi imatha kuchitika popanda kuyimitsa zida firiji. Njirayi imatha nthawi komanso yovuta, ndipo tanthauzo lake ndi losauka.

2. Pa defrosting, siyani compresyar kapena siyani kudyetsa madzi kwa Evaporator. Kutumiza Magetsi kumakhala ndi maubwino otsika mtengo komanso kuwongolera kosavuta, koma mtengo wogwira ntchito ndi wokwera. Nthawi zambiri amagwiritsa ntchito posankha zida zosungiramo zozizira, osati zonyoza zida zothandizira firiji. Kwa kutentha kosiyanasiyana, zofunikira pakuwongolera ziyenera kukhala zosiyana, ndipo mphamvu yozizira iyeneranso kukhala yosiyana. Kukhazikitsidwa kwa malo ozizira kumayenera kusinthidwa malinga ndi malo ogwiritsira ntchito a kasitomala ndi kugwiritsa ntchito, pokhapokha palibe chofunikira kutenga njira yosinthira.

3. Dongosolo lotentha la mpweya limakhala lovuta ndipo mtengo wake ndi wokwera. Koma kusintha kwa tanthauzo kuli bwino. Akagwiritsidwa ntchito mu dongosolo la ammonia, mafuta omwe amapezeka mu Evaporator amathanso kusinthidwa kukhala kukhetsa kapena kutsitsidwa kosiyanasiyana kozungulira. Mukukonzekera mafuta otentha a mafuta, kukakamizidwa kumayang'aniridwa pa 0.6mpu. Yesani kugwiritsa ntchito gasi wokwera kwambiri kuchokera ku compressi imodzi ya gawo limodzi kuti musunthe. Zima imatha kukhala yoyenera kuchepetsa madzi ozizira kapena kuchepetsa kuchuluka kwa kutsitsa, kuwonjezera kutentha kwamphamvu, kumafupikitsa nthawi yotulutsa. Kwa ma ammonia dongosolo, ma ammonia otentha kuti aletse kuyenera kulumikizidwa ndi chitoliro cha mafuta.

4. Kutulutsa kwamadzi ndikuthira madzi pansi pa epaptoratora ndi chipangizo chopukusira kuti chisungunuke chisanu. Dongosolo lolowera madzi lili ndi malo ovuta komanso mtengo wokwera, koma zabwino ndi mtengo wotsika. Kutulutsa kwamadzi kumatha kuchotsa chisanu ku chisanu kuchokera ku Evaporator pamtunda, ndipo sangathetse kuvuta kwa kudzikundikira kwamafuta ku Evaptorat pa kusamutsa kutentha. Chofunikira kwambiri ndi bolodi yosungirako kozizira, yomwe nthawi zambiri imapangidwa pasadakhale ndi opanga ozizira ndipo ili ndi kutalika kokhazikika, m'lifupi komanso makulidwe. Bungwe losungirako 100mm nthawi zambiri limagwiritsidwa ntchito posungira komanso sing'anga ozizira, 120mm kapena 150mm yosungirako ozizira nthawi zambiri imagwiritsidwa ntchito posungira kutentha ndi kuzizira kochepa.

5. Kutulutsa madzi otentha ndi njira ziwiri zokomera kutentha ndi kulowa kwamadzi nthawi yomweyo, zomwe zimangochotsa maubwino a zonse, ndipo amatha kuchotsa bwino chisanu padziko lapansi ndikuchotsa mafuta mkati mwa epaporator. Pokana, mpweya wotentha umatumizidwa koyamba kuti upatule kuti uletse chisanu kuchokera pamtunda kuchokera pamtunda, kenako madziwo amathiridwa mwachangu kuti azisambitsa chisanu. Madzi atadulidwa, pamwamba pa eyapator ndi "yowuma" ndi mpweya wotentha kuti muchepetse mawonekedwe amadzi ozizira ndikusokoneza kusamutsa kutentha. M'mbuyomu, opanga ozizira ozizira amagwiritsa ntchito polyethylene ndi polystyrene ngati zida. Tsopano pali ntchito yabwino kwa mchenga wa polyuretherane. Kuchulukitsa kwa polystyrene kutengera kwachuma ndikochepa, sikungakhale kwamizidwa. Nthawi zambiri amagwiritsidwa ntchito pazida zapadera. Polyethylene ndi zinthu zabwino. Kudzera munthawi ina, ikhoza kuphedwa mu kachulukidwe koyenera, chifukwa cha kutchinga ndichabwino, kubzala mphamvu ya makulidwe. Pulogalamu ya polyurethane ndiyabwino, ili ndi ntchito yabwino kwambiri ndipo sizitenga chinyezi, koma mtengo wozizira wozizira uku ndi wokwera pang'ono.
