Ngati tikufuna kumanga kusungirako kuzizira, gawo lofunika kwambiri ndi gawo la firiji la malo ozizira, choncho ndikofunika kwambiri kusankha firiji yoyenera.
Nthawi zambiri, malo osungira ozizira omwe amapezeka pamsika amagawidwa m'mitundu iyi
Malinga ndi mtunduwo, imatha kugawidwa m'magawo oziziritsa madzi komanso mayunitsi oziziritsa mpweya.
Magawo oziziritsa madzi amakhala ochepa chifukwa cha kutentha kozungulira, ndipo magawo oziziritsidwa ndi madzi savomerezedwa m'malo ochepera ziro.
Chodziwika kwambiri pamsika wonse ndi mafiriji oziziritsa mpweya. Kotero tiyeni tiyang'ane pa mayunitsi a mpweya wozizira.
Kuti tiphunzire gawo la firiji, choyamba tiyenera kumvetsetsa kamangidwe ka chipindacho
1. Refrigeration Compressor
Mitundu ya ma compressor ozizira ozizira ndi awa: Semi-hermetic cold storage compressor, screw cold storage compressor ndi scroll cold storage compressor.
3. nkhokwe yamadzimadzi
Iwo akhoza kuonetsetsa khola refrigerant madzi otaya mpaka mapeto.
Madzi osungiramo madzi amakhala ndi chizindikiro chamadzimadzi, chomwe chimatha kuwona kusintha kwamadzimadzi komanso ngati pali firiji yochuluka kapena yochepa kwambiri mu dongosolo malinga ndi katundu.
4. Valavu ya Solenoid
Solenoid valve coil imapatsidwa mphamvu kapena kupatsidwa mphamvu kuti izindikire pompopompo yozimitsa yokha.
Sakanizani kompresa
Pamene zosungirako zozizira ndi zofunikira zoziziritsa ndizochepa, compressor ya mpukutu ingagwiritsidwe ntchito.
2. Olekanitsa mafuta
Ikhoza kulekanitsa mafuta a refrigerant ndi mpweya wa refrigerant mu utsi.
Nthawi zambiri, kompresa iliyonse imakhala ndi cholekanitsa mafuta. Kutentha kwapamwamba ndi mpweya wothamanga kwambiri wa refrigerant ndi mafuta a furiji amayenda kuchokera mumtsinje wa mafuta, ndipo mafuta a furiji amasiyidwa pansi pa cholekanitsa mafuta. Mpweya wa refrigerant ndi mafuta pang'ono a refrigerant amatuluka kuchokera munjira yamafuta ndikulowa mu condenser.
5. Gawo la condenser
Monga chida chofunikira chosinthira kutentha mufiriji, kutentha kumasunthidwa kuchokera ku nthunzi yotentha kwambiri ya refrigerant yokhala ndi kutentha kwambiri komanso kuthamanga kwambiri kupita ku condensing sing'anga kudzera mu condenser, ndipo kutentha kwa nthunzi ya refrigerant kumatsika pang'onopang'ono mpaka kumachulukira ndikukhazikika kukhala madzi. Wamba condensing TV ndi mpweya ndi madzi. Kutentha kwa condensation ndi kutentha komwe mpweya wa refrigerant umakhazikika kukhala madzi.
1) Evaporative condenser
Evaporative condenser ili ndi maubwino otengera kutentha kwakukulu, kutulutsa kwakukulu komanso kusiyanasiyana kogwiritsa ntchito.
Kutentha kozungulira kukakhala kocheperako, siyani fani, ingoyatsa mpope wamadzi ndikugwiritsa ntchito firiji yokhayokha.
Kutentha kumatsika pansi pa malo oundana, tcherani khutu ku antifreeze ya madzi.
Pamene katundu wa dongosolo ali wamng'ono, pamaziko owonetsetsa kuti kupanikizika kwa condensation sikuli kokwera kwambiri, ntchito ya evaporative yozizira yozungulira mpope wa madzi ikhoza kuyimitsidwa ndipo kuziziritsa kwa mpweya kokha kungagwiritsidwe ntchito. Pa nthawi yomweyo, madzi amasungidwa mu evaporative madzi ozizira thanki ndi kulumikiza madzi chitoliro akhoza kutulutsidwa kupewa kuzizira, koma pa nthawi ino, mpweya polowera kalozera mbale ya evaporative kuzirala ayenera kutsekedwa kwathunthu. Njira zodzitetezera pakugwiritsa ntchito pampu yamadzi ndizofanana ndi za condenser yamadzi.
Pogwiritsa ntchito evaporative condensation, ziyenera kudziwidwa kuti kukhalapo kwa mpweya wosasunthika m'dongosolo kumachepetsa kwambiri kutentha kwa mpweya wa condensation, zomwe zimapangitsa kuti pakhale kuthamanga kwakukulu kwa condensation. Chifukwa chake, ntchito yotulutsa mpweya iyenera kuchitidwa, makamaka m'magawo otsika otsika omwe ali ndi kukakamiza koyipa kwa firiji.
Phindu la pH la madzi ozungulira liyenera kusungidwa nthawi zonse pakati pa 6.5 ndi 8.
2) mpweya utakhazikika condenser
Mpweya woziziritsa mpweya uli ndi ubwino womanga bwino ndikungopereka magetsi kuti agwire ntchito.
Semi-hermetic ozizira yosungirako kompresa
Pamene mphamvu ya firiji yosungirako kuzizira imayenera kukhala yaikulu koma kukula kwa polojekiti yosungirako kuzizira kumakhala kochepa, makina osungira ozizira a Semi-hermetic amasankhidwa.
Mpweya wotsekemera ukhoza kuikidwa panja kapena padenga, zomwe zimachepetsa kugwira ntchito kwa malo ogwira ntchito komanso zofunikira pa malo opangira ogwiritsira ntchito. Mukamagwira ntchito nthawi yayitali, pewani kuyika ma sundries mozungulira cholumikizira kuti musasokoneze kayendedwe ka mpweya. Onetsetsani nthawi zonse ngati pali kutayikira komwe kukuganiziridwa ngati banga lamafuta, mapindikidwe ndi kuwonongeka kwa zipsepse. Nthawi zonse muzigwiritsa ntchito mfuti yamadzi yothamanga kwambiri kuti muthamangitse. Onetsetsani kuti mwadula mphamvu ndikuyang'ana chitetezo panthawi yamagetsi.
Nthawi zambiri, kupanikizika kumagwiritsidwa ntchito kuwongolera kuyambika ndi kuyimitsa kwa fan yotsitsa. Chifukwa condenser imagwira ntchito panja kwa nthawi yayitali, fumbi, sundries, ubweya, ndi zina zotero zimakhala zosavuta kuyenda mu koyilo ndi zipsepse ndi mpweya ndi kumamatira ku zipsepse ndikupita kwa nthawi, zomwe zimabweretsa kulephera kwa mpweya wabwino komanso kuwonjezeka kwa kupanikizika kwa condensing. Chifukwa chake, ndikofunikira kuyang'ana nthawi zonse ndikusunga zipsepse za condenser zoziziritsa mpweya zoyera.
wononga mtundu ozizira yosungirako kompresa
Pamene mphamvu ya firiji yosungirako kuzizira imakhala yaikulu komanso kukula kwa polojekiti yosungirako kuzizira kumakhala kwakukulu, compressor yamtundu wozizira wozizira imasankhidwa.
