Momwe mungathetsere vuto la kubwerera kwamafuta kwamafuta ozizira?

Pali njira ziwiri zobweretsera mafuta ku kompresa, imodzi ndikubwezera kwamafuta olekanitsa mafuta, ina ndiyo kubwerera kwa mafuta kwa chitoliro chobwezera mpweya. Olekanitsa mafuta amaikidwa pa chitoliro cha compressor utsi. Nthawi zambiri, 50-95% yamafuta amatha kupatulidwa. Mafuta obwezeretsa mafuta ndiabwino, liwiro limathamanga, ndipo kuchuluka kwamafuta omwe amalowa mu payipi amachepetsedwa kwambiri, motero kupititsa patsogolo ntchito popanda kubwerera kwamafuta. nthawi.

Sizachilendo kuzizira kwa mafiriji okhala ndi mapaipi ataliatali kwambiri, makina opangira madzi oundana amadzimadzi athunthu, ndi zida zowumitsa ndi kuzizira kotsika kwambiri kuti zibwerere kupitilira mphindi khumi kapena ngakhale mphindi zambiri mutangoyamba kumene, kapena ndi zochepa kwambiri mafuta kubwerera. Kupanga Makina oyipa amachititsa kuti kompresa iime chifukwa chakuchepa kwamafuta. Kukhazikitsa kwa mafuta olekanitsa mafuta kwambiri mufiriji kumatha kukulitsa nthawi yopanda kubwerera kwa kompresa, kuti kompresa idutse bwino gawo lamavuto osabwerera mafuta pambuyo poyambira. .

Mafuta odzoza omwe sanalekanitsidwe amalowa m’dongosolo ndikuyenda ndi firiji mu chitoliro kuti apange mafuta. Mafuta odzoza atalowa mu evaporator, gawo lina la mafuta opaka mafuta amasiyanitsidwa ndi firiji chifukwa cha kutentha pang’ono ndi kusungunuka kochepa; Komano, kutentha kotsika komanso mamasukidwe akayendedwe okwera, mafuta olekanitsidwa ndi mafuta ndiosavuta kutsatira khoma lamkati la chitoliro, ndipo ndizovuta kuyenda. Kutsika kwa kutentha kwa nthunzi, kumakhala kovuta kwambiri kubwezera mafuta. Izi zimafuna kuti kapangidwe ndi kapangidwe ka payipi yotuluka nthunzi ndi payipi yobwerera iyenera kukhala yothandiza kuti mafuta abwerere. Chizoloŵezi chodziwika ndikutenga mapaipi otsika ndikuonetsetsa kuti kuthamanga kwa mpweya kukukulira.

Pazitsulo zamafriji okhala ndi kutentha pang’ono, kuphatikiza pakugwiritsa ntchito olekanitsa mafuta kwambiri, zosungunulira zapadera nthawi zambiri zimawonjezeredwa kuti zisalepheretse mafuta kutsekereza ma capillaries ndi ma valve owonjezera, ndikuthandizira kubweza mafuta. Nthawi yomweyo, anthu ena amagwiritsa ntchito mafuta opangira makina opangira mpweya m’malo mwa mafuta akunja. Pamwamba, imasungira ndalama, koma potengera mtengo wogwiritsa ntchito kwa nthawi yayitali, zidzangowonjezera mtengo wogwiritsira ntchito. Kuchita bwino kwa dongosololi kudzaipiraipira.

Mukugwiritsa ntchito moyenera, mavuto obwerera kwamafuta omwe amabwera chifukwa chosapanga bwino evaporator ndi mzere wobwerera siwachilendo. Kwa machitidwe a R22 ndi R404A, kubwerera kwamafuta kwa evaporator yodzaza madzi kumakhala kovuta kwambiri, ndipo mapaipi obwezeretsa mafuta pamakina amayenera kusamala kwambiri. Pazida zotere, kugwiritsa ntchito mafuta othamanga kwambiri kumatha kuchepetsa kwambiri mafuta omwe amalowa mu payipi, ndikuwonjezera nthawi yosabwerera ya chitoliro chobwezeretsa mpweya pambuyo poyambira.

Kompresa ndi apamwamba kuposa evaporator, mafuta kubwerera unakhota pa chitoliro ofukula kubwerera n’kofunika. Malo obwezera ayenera kukhala ophatikizika momwe angathere kuchepetsa kusungira mafuta. Kusiyanitsa pakati pamafuta obwerera kwamafuta kuyenera kukhala koyenera. Kuchuluka kwamafuta obwerera mafuta ndikokulirapo, mafuta owonjezera ayenera kuwonjezedwa. Mzere wobwezera mafuta wosinthira katundu uyeneranso kusamala. Katundu akatsika, liwiro la kubwerera kwa mpweya lidzatsika, liwiro lochepa kwambiri silothandiza kubwereranso kwamafuta. Pofuna kuonetsetsa kuti mafuta akubwerera pansi pamtengo wotsika, chitoliro chowongolera chimatha kutulutsa mapaipi owongoka kawiri.

Kuphatikiza apo, kuyambitsa kompresa pafupipafupi sikothandiza kuti mafuta abwerere. Popeza kompresa imayima kwakanthawi kochepa kopitilira ntchito, palibe nthawi yopanga khola lothamanga kwambiri mu chitoliro chobwerera, ndipo mafuta opaka mafuta amangokhala mu chitoliro. Ngati mafuta abwerera ndi ochepera mafuta a Ben, kompresa idzakhala yochepa mafuta. Nthawi yocheperako ikafupikira, mapaipi amatalika komanso dongosolo limakhala lolimba, vuto lamafuta obwerera limakhala lotchuka kwambiri. Chifukwa chake, mwambiri, musayambe kompresa pafupipafupi.

Mwachidule, kusowa kwamafuta kumayambitsa kusowa kwamafuta. Zomwe zimayambitsa kusowa kwamafuta si kuchuluka ndi kuthamanga kwa zotsekemera zamtundu wa wononga, koma kubwerera kwamafuta koyipa. Kukhazikitsidwa kwa olekanitsa mafuta kwambiri kumatha kubwereranso mafuta ndikuwonjezera nthawi ya kompresa popanda kubwerera kwamafuta. Kapangidwe ka evaporator ndi payipi ya gasi yobwerera iyenera kuganizira kubwerera kwamafuta. Njira zowakonzekeretsa monga kupewa poyambira pafupipafupi, kutaya nthawi, kubwezeretsanso nthawi kwa firiji, komanso kusintha kwakanthawi kwa zovala (monga mayendedwe) zimathandizanso kuti mafuta abwerere
