Magalasi amalonda - makabati oimirira chitsekotchulani makabati owonetsera zakumwa, zakumwa zoledzeretsa, ndi zina zotero. Ndi kapangidwe ka galasi - zitseko, amapezeka kwambiri m'masitolo akuluakulu, masitolo akuluakulu, m'masitolo ogulitsa zinthu zotsika mtengo, ndi zina zotero. Ponena za kuchuluka, amagawidwa m'magulu awiri - zitseko chimodzi ndi zitseko zambiri. Makabati a zitseko zambiri ali ndi malo ambiri komanso malo otakata, omwe amatha kusunga chakudya chochuluka. Makabati okhazikika awa amagwiritsa ntchito firiji yozizira ndi mpweya, yomwe ingalepheretse chisanu ndi ayezi mkati mwa kabati. Kutentha kumakhala pafupifupi 2 - 8°C chaka chonse.
Izi ndi zomwe zimatanthauzira mbali zofunika kwambiri za makabati okhazikika agalasi - zitseko:
Themakina a fanChimatanthauza chida chomwe chimadalira fani ngati njira yothandizira kutentha - kutayikira kapena kuzizira. Malingaliro ake ogwirira ntchito ndi osiyana ndi a firiji yachikhalidwe - yozizira mwachindunji. Faniyo imapangitsa kuti mpweya uziyenda mokakamizidwa mkati mwa firiji, zomwe zimapangitsa kuti mpweya wozizira uziyenda mofulumira komanso kuti mpweya wozizira uzifalikira m'kabati, kuchepetsa kusiyana kwa kutentha m'malo osiyanasiyana, ndikupangitsa kuti firiji ikhale yofanana.
Makabati ambiri oyima ndi ozizira mpweya kapena ozizira mpweya ndi ozizira mwachindunji. Amadalira fan kuti ayendetse mpweya wozizira ndipo safuna kusungunuka ndi manja (fani imapukutira chisanu pa evaporator kuti isungunuke ndikutulutsa). Mtundu wosakanikirana umaphatikiza ubwino wa kuzizira mwachangu komanso kutentha kofanana kwa fan.
Ubwino wake ndi woonekeratu. Kugwiritsa ntchito bwino kwa firiji ndi kwakukulu, ndipo kutentha kwake ndi kokhazikika. Ndikoyenera kusungiramo zinthu zomwe zimakhala zosavuta kutentha ndipo zimachepetsa vuto la kusungunuka ndi madzi pamanja.
Dziwani kuti ntchito ya fan ingapangitse phokoso pang'ono, ndipo chifukwa cha mpweya wozungulira, zosakaniza zimatha kuuma chifukwa cha kutayika kwa madzi. Nthawi zambiri, imafunika kugwiritsidwa ntchito limodzi ndi chosungira chinyezi.
Themakabati owongokaNdi zinthu zazing'ono zozungulira zomwe zimayikidwa pansi pa chipangizocho. Ntchito yawo yayikulu ndikuthandiza kuyenda ndi kusintha malo a firiji. Kapangidwe kake nthawi zambiri kamaganizira mphamvu ya katundu, yomwe imayenera kufanana ndi kulemera kwa firijiyo kuti itsimikizire kukhazikika komanso kusagwedezeka panthawi yoyenda. Ali ndi ntchito yoletsa kutsekeka (monga chipangizo choletsa kutsekeka), chomwe chingatsekedwe mutayikidwa kuti chisatsetseke mwangozi ndikuwonetsetsa kuti chikugwiritsidwa ntchito bwino.
Ponena za zipangizo, mphira wopirira kukalamba ndi dzimbiri umagwiritsidwa ntchito kwambiri, zomwe sizingochepetsa kukalamba pansi komanso zimasinthasintha malinga ndi malo okhala chinyezi monga makhitchini ndikuwonjezera nthawi yogwirira ntchito. Kapangidwe kake, nthawi zambiri kamaphatikizidwa ndi zinthu zothandizira pansi pa kabati yoyimirira, poganizira kusavuta kwa kuyenda komanso kukhazikika kwake ikayikidwa.
Thepulagi yowongoka ya kabatindi gawo lofunika kwambiri lomwe limalumikiza firiji ndi soketi yamagetsi. Ntchito yake yayikulu ndikulowetsa magetsi amagetsi mufiriji kuti ipereke mphamvu kuzinthu monga compressor ndi control system yake.
Mwa kapangidwe kake, ndi pulagi ya ma pin atatu. Ma pin awiri ndi waya wamoyo ndi waya wopanda mbali, womwe umayang'anira kutumiza mphamvu zamagetsi. Pini yachitatu ndi waya wapansi, womwe umalumikizidwa ku chipolopolo chachitsulo cha firiji. Ngati kabati yoyimirira yatuluka, mphamvu yamagetsi imatha kulowetsedwa pansi kuti isagwedezeke ndi magetsi m'thupi la munthu ndikuwonetsetsa kuti ikugwiritsidwa ntchito bwino.
Mphamvu yoyezedwa ya pulagi imafanana ndi mphamvu yake (nthawi zambiri, pazida zomwe zili ndi mphamvu yochepa, mphamvu yoyezedwa ya pulagi ndi pafupifupi 10A). Zipangizozo ndi zapulasitiki zokhala ndi kutentha kolimba komanso kutchinjiriza. Zoyikamo zitsulo zamkati zimapangidwa ndi zinthu zamkuwa zomwe zimakhala ndi mphamvu zamagetsi zabwino kwambiri kuti zitsimikizire kuti mphamvu yotumizira magetsi ikuyenda bwino.
Tiyenera kuzindikira kuti mukamagwiritsa ntchito, ndikofunikira kuonetsetsa kuti pulagi ndi soketi zikugwirizana bwino kuti tipewe mavuto monga kusagwirizana bwino ndi kutentha komwe kumachitika chifukwa cha kutayirira.
Kabati iliyonse yoyima yamalonda ili ndi switch yathunthu yamagetsi, batani losintha kutentha, batani lowunikira, ndi chophimba chowonetsera kutentha. Malinga ndi mitundu yosiyanasiyana, njira zosiyanasiyana zopangira zimagwiritsidwa ntchito. Zovala zapamwamba nthawi zambiri zimagwiritsa ntchito kapangidwe ka sikirini yokhudza, yomwe imawoneka yapamwamba, koma mtengo wake ndi wokwera kwambiri kuposa kapangidwe ka makina. Ngati yawonongeka, ndalama zokonzera zimakhalanso zapamwamba kwambiri. Chifukwa chake, zambiri zimapangidwa ngati mabatani amakina, omwe samangokhala ndi nthawi yayitali yogwirira ntchito komanso ndi osavuta kusintha zida zosinthira. Chofunika kwambiri, zonse zimapangidwa ndi zinthu zosalowa madzi, zoteteza tizilombo, ndi zina zotero. Pali ukonde wosalowa fumbi mkati ndi chophimba chosalowa madzi kunja.
Nkhaniyi ikubweretsa mfundo zitatu izi. Mu nkhani yotsatira, tipereka zinthu zofunika kwambiri pa kabati yoyimirira monga compressor ndi cooler.
