Chipinda chozizira chozizira mwachangu chimachepetsa kutentha kwa zinthu mwachangu. Chimateteza ubwino ndi kapangidwe ka chakudya. Mafakitale ambiri amagwiritsa ntchito nyama, nsomba, ndi ndiwo zamasamba. Chipindacho chimachepetsa kutentha kwapakati mwachangu. Makina ambiri amaundana zinthu kuyambira +20°C mpaka -18°C mwachangu. Nthawi yozizira nthawi zambiri imakhala pansi pa maola 4. Kuzizira mwachangu kumachepetsa kukula kwa makristalo a ayezi. Makristalo ang'onoang'ono amateteza kapangidwe ka maselo. Njirayi imasunga kukoma, mtundu, ndi zakudya. Mafakitale ambiri amaika zipinda zozizira mwachangu m'mizere yopangira. Chipindacho chimathandizira kutulutsa bwino kwambiri komanso khalidwe lokhazikika. Opanga chakudya amadalira njira iyi kuti atumize kunja ndi kusungira kwa nthawi yayitali.
Kuchuluka kwa Kutentha ndi Kugwira Ntchito kwa Chipinda Chozizira Chozizira Mwachangu
Kutentha kozizira kwa chipinda chozizira chomwe chimazizira mwachangu nthawi zambiri kumakhala -15～-35℃, komwe kumafanana ndi kwamalo osungira ozizira otsika kutenthaKusiyana kwakukulu pakati pa malo osungiramo ozizira mwachangu ndi malo osungiramo ozizira otsika kutentha ndi liwiro la kuzizira. Poyerekeza ndi wambachipinda choziziraChipinda chozizira chomwe chimazizira mwachangu chingachepetse kutentha kwa zinthu mwachangu, zomwe zimawathandiza kuti adutse mwachangu m'dera lomwe limapanga makristalo ambiri a ayezi.
Mukazizira, chinyezi chambiri chomwe chili mkati mwa chakudya chimazizira pa -1~-5℃. Chifukwa chake, -1~-5℃ imatchedwanso malo opangira ma crystal a ayezi. Mukazizira kwambiri, kuchuluka kwa madzi kumawonjezeka, ndipo kapangidwe ka mkati mwa zakudya zambiri, komanso mawonekedwe a mapuloteni, sikudzasinthika.
Kutentha kwapakati pa chakudya kukakhala nthawi yayitali pamalo opangira makristalo a ayezi, makristalo ambiri a ayezi amakhala mkati, ndipo chakudyacho chidzawonongeka kwambiri. Chakudya chidzataya kukoma kwake kolimba, ndipo kukoma kwake koyambirira kudzatayikanso. Zonsezi zimachitika chifukwa cha njira zosayenera zoziziritsira. Chipinda chozizira chozizira mwachangu chasintha njira yozizira yomwe inkachepetsa pang'onopang'ono kutentha kwapakati pa zinthu, pogwiritsa ntchito mpweya wozizira wambiri mbali zosiyanasiyana kuti idutse mwachangu kutentha kwapakati pa zinthu kudzera m'dera lopangira makristalo a ayezi.
Mwanjira imeneyi, ma crystals akuluakulu okha ndi omwe adzapangidwe kunja, ndipo mkati mwake mudzasungidwa bwino. Chifukwa chake, chakudya chosungidwa m'chipinda chozizira chomwe chimazizira mwachangu chimatha kusunga kapangidwe kake koyambirira mpaka pamlingo wokwanira, ndipo nthawi zambiri chimakhala ndi kukoma ndi kukoma kwabwino.
Makhalidwe Ofunika Kwambiri a Chipinda Chozizira Chozizira Mwachangu
Chipinda chozizira mwachangu chimagwiritsa ntchito kutenthetsa kwambiri. Kukhuthala kwa panelo nthawi zambiri kumafika 120 mm mpaka 150 mm. Mapanelo a PU amapereka mphamvu yotenthetsera pafupifupi 0.022 W/m·K. Mapanelo a PIR amathandizira kukana moto. Kapangidwe ka chipindacho kamakhala ndi pansi zolimba. Pansi pake pamakhala katundu wolemera kuyambira 2,000 mpaka 5,000 kg/m². Malo a aluminiyamu kapena chitsulo chosapanga dzimbiri amathandizira chitetezo.
Zitseko zimagwiritsa ntchito mafelemu otenthedwa. Zotenthetsa zitseko zimagwiritsa ntchito mphamvu ya ma watts pafupifupi 60 mpaka 120. Zotenthetsa izi zimaletsa kusonkhana kwa ayezi. Zotsekera zolimba zimachepetsa kutuluka kwa mpweya. Kukula kwa chipinda kumasiyana malinga ndi kukula kwa ntchito. Zipinda zazing'ono zimakhala 20 m². Zipinda zazikulu zamafakitale zimaposa 300 m². Kutalika kwa denga nthawi zambiri kumakhala pakati pa 3 m mpaka 6 m. Kapangidwe kolimba kamachepetsa kutentha ndi kupitirira 25%. Kuteteza uku kumalola kugwira ntchito bwino pakasinthasintha kwambiri kutentha.
Dongosolo la Firiji ndi Zigawo za Chipinda Chozizira Chozizira Mwachangu
Dongosolo loziziritsa limapanga maziko a ntchito yoziziritsa mwachangu, makamaka m'chipinda chozizira chozizira mwachangu. Kusintha kwa kutentha m'chipinda chozizira chozizira mwachangu sikuchepa pang'onopang'ono. M'malo mwake, kumatsika kufika pa -40 ℃ mwachangu, kenako kumachira pang'onopang'ono, ndipo pamapeto pake kumalamulira kutentha pa -18 ℃. Chifukwa chake, chipinda chozizira chozizira mwachangu nthawi zambiri chimayika zida zoziziritsira zamagetsi amphamvu kwambiri.
Makina ambiri amagwiritsa ntchito ma compressor okwirira kapena ozungulira pang'ono. Ma compressor okwirira amakwanira mphamvu zopitirira 50 kW. Mphamvu yoziziritsira imakhalabe yokwera. Chipinda choziziritsira cha 50 m² nthawi zambiri chimafuna mphamvu ya 40 mpaka 60 kW. Chipinda cha 200 m² chingafunike mphamvu ya 150 mpaka 250 kW.
Dongosololi limaphatikizapo ma evaporator, ma condenser, ma expansion valve, ndi ma olekanitsa mafuta. Ma evaporator amagwiritsa ntchito mtunda wautali wa zipsepse. Mpata wa zipsepse nthawi zambiri umakhala pakati pa 8 mm ndi 12 mm. Kapangidwe kameneka kamaletsa kutsekeka kwa chisanu.
Mafiriji akuphatikizapo R404A, R507A, ndi ammonia. Makina a ammonia amagwira ntchito bwino kwambiri. Makina a ammonia amachepetsa kugwiritsa ntchito mphamvu ndi 15% mpaka 20%. Mafani omwe ali mkati mwa makina otulutsa mpweya amapereka mpweya wamphamvu. Liwiro la mpweya nthawi zambiri limafika 3 mpaka 6 m/s. Mpweya wambiri umachotsa kutentha pamwamba mwachangu. Makinawa amatsimikizira kuzizira mwachangu komanso mofanana.
Kapangidwe ka Mpweya ndi Ubwino wa Kuzizira kwa Zinthu
Kuyenda kwa mpweya kumatanthauza momwe mpweya umagwirira ntchito bwino. Zipinda zozizira zomwe zimazizira mwachangu zimagwiritsa ntchito mphamvu yokakamiza. Mafani amakankhira mpweya wozizira mwachindunji pamwamba pa zinthu. Kuchuluka kwa mpweya womwe umayenda nthawi zambiri kumakhala pakati pa 20,000 ndi 40,000 m³/h. Liwiro la mpweya kuzungulira zinthu limakhala lofanana. Kuyenda kwa mpweya kofanana kumalepheretsa kuzizira kosagwirizana.
Kutalikirana kwa zinthu kumafunikanso. Mathireyi nthawi zambiri amakhala ndi mipata ya 30 mpaka 50 mm. Kutalikirana kumeneku kumalola kuti mpweya uziyenda bwino. Kutalikirana kwabwino kumafupikitsa nthawi yozizira ndi 20%. Dongosololi limaundana zinthu mofanana. Kutentha kwapakati kumafika -18°C mwachangu. Kuzizira kosagwirizana kumayambitsa kuwonongeka kwa kapangidwe kake. Kuyenda kwa mpweya mwamphamvu kumaletsa chiopsezo ichi. Zodulira mpweya zimatsogolera njira yoyendamo mpweya. Zodulira izi zimachepetsa madera akufa. Dongosolo la mpweya limatsimikizira kuti kuzizira kokhazikika kwa gulu lililonse kuli bwino.
Ntchito Zokhudza Makampani Ogulitsa Zakudya
Zipinda zozizira mofulumira zimatumikira mafakitale ambiri. Okonza nsomba zam'madzi amaundana ndi nkhanu, nsomba, ndi squid. Zomera zambiri zimakonza matani awiri mpaka khumi patsiku. Okonza nyama amaundana ndi ng'ombe, nkhumba, ndi nkhuku. Okonza ndiwo zamasamba amaundana ndi nandolo, chimanga, ndi zipatso. Mafakitale okonzekera chakudya amaundana ndi mbale zokonzedwa. Kuwongolera magawo ndi kapangidwe kosungiramo kuzizira mwachangu.
Malo osungiramo zinthu zozizira amagwiritsa ntchito zipinda zoziziritsira mwachangu musanasunge. Gawoli limalimbitsa zinthu zisananyamulidwe kwa nthawi yayitali. Kugwiritsidwa ntchito kwakukulu kumasonyeza kufunika kwa makinawa m'mafakitale.
Machitidwe Owongolera ndi Zokha
Zipinda zamakono zozizira mofulumira kwambiri zimagwiritsa ntchito njira zowongolera zanzeru. Olamulira a PLC amawongolera kutentha ndi kuyenda kwa mpweya. Masensa amawunika kutentha, kuthamanga, ndi liwiro la fan. Kulondola kwa kutentha kumakhala mkati mwa ±1°C. Zowunikira zogwira zimawonetsa deta yeniyeni. Ogwiritsa ntchito amasintha makonda mosavuta. Ma alamu amayamba kugwira ntchito mkati mwa masekondi 5 akalakwitsa.
Kugwiritsa ntchito makina okha kumachepetsa zosowa za ogwira ntchito. Wogwira ntchito m'modzi akhoza kuyang'anira zipinda zingapo. Kusunga deta kumathandiza kuwunika kwabwino. Kuyang'anira patali kumalola kuyang'aniridwa kunja kwa malo. Machitidwewa amawonjezera kudalirika ndikuchepetsa chiopsezo cha ntchito.
