Chipinda chozizira chozungulira chimagwira ntchito yofunika kwambiri pakusunga chakudya, mankhwala, ndi zinthu zina. Kufunika kwakukulu padziko lonse lapansi kosungirako zinthu zotentha kukupitilira kukula msika uno. Malinga ndi Global Cold Chain Alliance, mphamvu yosungiramo zinthu zozizira padziko lonse lapansi idapitilira ma cubic metres 720 miliyoni mu 2024. Chipinda chozizira chozungulira chimadziwika chifukwa cha kusinthasintha, kuyika mwachangu, komanso magwiridwe antchito okhazikika a kutentha.
Kapangidwe ndi Zigawo Zazikulu za Zipinda Zozizira Zokhazikika
Choyimirachipinda choziziraZimakhala ndi mapanelo otetezedwa kale, makina oziziritsira, mayunitsi owongolera, ndi zowonjezera zotsekera. Mapanelo otetezedwa nthawi zambiri amagwiritsa ntchito polyurethane kapena PIR thovu cores. Malinga ndi zofunikira zenizeni za kutentha kozizira, makulidwe a panel amakhala kuyambira 75 mm mpaka 200 mm. A 100 mmgulu la polyurethanenthawi zambiri imakhala ndi mphamvu yoyendetsera kutentha ya 0.022 W/m·K, yomwe imakwaniritsa zosowa zambiri zosungira kutentha kwapakati.
Malo oimikapo mapanelo amagwiritsa ntchito chitsulo chopakidwa utoto kapena chitsulo chosapanga dzimbiri. Kukhuthala kwa chitsulo nthawi zambiri kumakhala pakati pa 0.4 ndi 0.6 mm. Zipangizozi zimalimbana ndi dzimbiri ndipo zimathandiza kuyeretsa pafupipafupi. Makina otsekera ma cam-lock kapena ma hook-lock amalumikiza mapanelo mwamphamvu. Kapangidwe kameneka kamachepetsa kutuluka kwa mpweya kufika pansi pa 0.5 m³/m²·h poyesa kuthamanga kwa mpweya.
Makina oziziritsira amapanga maziko ogwirira ntchito. Mitundu yodziwika bwino ya compressor imaphatikizapo ma piston ozungulira ndi ozungulira. Mphamvu yoziziritsira nthawi zambiri imakhala pakati pa 3 kW mpaka 50 kW pa dongosolo lililonse. Zipinda zozizira zapakati zimagwira ntchito pakati pa 0°C ndi 5°C. Zipinda zozizira zotsika zimafika −18°C mpaka −25°C. Zowongolera zamagetsi zimasunga kulondola kwa kutentha mkati mwa ±0.5°C.
Zitseko zimakhudzanso magwiridwe antchito. Zitseko zokhala ndi ma hinged kapena zotsetsereka nthawi zambiri zimakhala ndi mafelemu a zitseko otentha. Kapangidwe kameneka kamaletsa kupangika kwa chisanu pamene chikugwira ntchito pansi pa −10°C. Kuphatikiza bwino kwa zigawo zake kumatsimikizira kuti ntchito yake ndi yokhazikika komanso kuti ikhale nthawi yayitali.
Ubwino Waukulu wa Makina Ozizira a Zipinda Zozizira
Zipinda zozizira zokhazikika zimapereka mphamvu yomanga bwino kwambiri. Mapanelo opangidwa kale m'fakitale amachepetsa ntchito pamalopo. Chifukwa cha mapanelo otenthetsera omwe amapangidwa kale komanso kuchuluka kwa magulu omanga, chipinda chozizira chokhazikika cha 100 m² nthawi zambiri chimatha kukhazikitsidwa mkati mwa masiku 3-7. Zipinda zozizira zachikhalidwe za konkriti nthawi zambiri zimafuna masiku opitilira 30. Kutumiza mwachangu kumachepetsa ndalama zogwirira ntchito ndi pafupifupi 25%.
Kusinthasintha ndi ubwino wina waukulu. Makina ozungulira amalola kukulitsa kapena kusamutsa mosavuta. Ogwiritsa ntchito amatha kuwonjezera kuchuluka kwa malo osungiramo zinthu powonjezera mapanelo ndikukweza mphamvu ya firiji. Kusinthasintha kumeneku kumagwirizana ndi kusungira chakudya cha nyengo ndi ntchito zoyendetsera zinthu zomwe zikukula.
Kugwiritsa ntchito mphamvu moyenera kudakali phindu lalikulu. Thovu la polyurethane lokhala ndi mphamvu zambiri limafika pa 40–45 kg/m³. Kapangidwe kameneka kamachepetsa kusamutsa kutentha ndikuchepetsa nthawi yogwiritsira ntchito compressor. Kafukufuku akuwonetsa kuti zipinda zozizira zokhazikika zimatha kuchepetsa kugwiritsa ntchito mphamvu ndi 15–20% poyerekeza ndi zosungira zozizira zopangidwa ndi njerwa pansi pa mikhalidwe yofanana.
Kuwongolera ukhondo kumakulanso. Malo osalala achitsulo amachepetsa kukula kwa mabakiteriya. Zipinda zozizira zomwe zimagwiritsidwa ntchito posungira chakudya nthawi zambiri zimatsatira miyezo ya HACCP. Kutseka bwino kumaletsa kuuma ndi kupanga nkhungu. Izi zimathandiza kusungira nyama, mkaka, zipatso, ndi ndiwo zamasamba mosamala.
Kuwongolera mtengo kumalimbitsanso kukongola kwa msika. Zipinda zozizira za modular nthawi zambiri zimachepetsa ndalama zoyambira ndi 10-20% poyerekeza ndi nyumba zosungiramo zinthu zozizira zachikhalidwe. Kugwiritsa ntchito zinthu zomwe zimayembekezeredwa komanso kupanga kokhazikika kumathandiza kuwongolera bajeti molondola.
Kukhazikitsa, Kukonza, ndi Moyo Wotumikira
Kukhazikitsa mwaukadaulo kumatsimikizira kudalirika kwa nthawi yayitali. Okhazikitsa ayenera kulinganiza maziko mkati mwa ±5 mm pa mamita 10. Maziko osafanana amachititsa kuti pakhale kupsinjika kwa panel komanso mpweya wotuluka. Okhazikitsa ayenera kulimbitsa ma cam-locks mofanana kuti pakhale kulumikizana kwa panel.
Ntchito yotseka imafuna chisamaliro chapadera. Oyika amaika silicone yofanana ndi chakudya pamalo onse olumikizira mapanelo. Zotchinga za nthunzi ziyenera kukhalabe zokhazikika, makamaka m'zipinda zozizira kwambiri. Kutseka kosayenera kumawonjezera kuzizira ndipo kumawonjezera kugwiritsa ntchito mphamvu ndi 30%.
Kukhazikitsa makina oziziritsira pambuyo pokhazikitsa. Akatswiri ayenera kutsuka makinawo ndi utsi wochepera ma microns 500 asanadzaze firiji. Kuchaja koyenera kwa firiji kumathandiza kuti compressor igwire bwino ntchito komanso kuchepetsa kuwonongeka. Mafiriji wamba ndi monga R404A, R448A, ndi R507A, kutengera malamulo a m'deralo.
Kukonza nthawi zonse kumawonjezera nthawi yogwira ntchito. Ogwiritsa ntchito ayenera kuyeretsa ma condenser mwezi uliwonse kuti asunge kutentha bwino. Ma gasket a zitseko amafunika kufufuzidwa miyezi isanu ndi umodzi iliyonse. Kukonza bwino kumathandiza kuti zipinda zozizira zigwire ntchito bwino kwa zaka 15-20.
Malo achitsulo okhala ndi zokutira zotsutsana ndi dzimbiri amalimbana ndi dzimbiri m'malo onyowa. Pogwiritsa ntchito bwino komanso kukonza bwino, mphamvu ya zinthu zotetezera kutentha imakhalabe pansi pa 5% pazaka khumi. Kulimba kumeneku kumathandiza kuti ntchito ikhale yolimba kwa nthawi yayitali.
Zipinda zozizira za Modular zimapereka njira zosungiramo zinthu zozizira bwino, zosinthasintha, komanso zosunga mphamvu. Zigawo zokhazikika zimathandizira kapangidwe ndi kuyika. Magawo olondola a kutentha amatsimikizira kuwongolera kutentha kokhazikika. Ndi zomangamanga mwachangu, ndalama zochepa, komanso moyo wautali wautumiki, zipinda zozizira za Modular zikupitilizabe kuthandizira chitukuko cha unyolo wozizira padziko lonse lapansi m'mafakitale azakudya, mankhwala, ndi mayendedwe.
Sankhani wopereka chithandizo mosamala
Ubwino wa malo osungiramo zinthu zozizira modular uli makamaka pakupanga kosavuta komanso kugwiritsa ntchito bwino ndalama. Izi zimapangitsa kuti opereka njira zosungiramo zinthu zozizira azifunika kwambiri.
Kumbali imodzi, opereka chithandizo ayenera kukhala ndi luso linalake logwirizanitsa zinthu mkati mwa makampani osungira zinthu zozizira. Izi zimapangitsa kuti zikhale zosavuta kwa opereka chithandizo kugula zinthu zosiyanasiyana ndikukwaniritsa zosowa za ogwiritsa ntchito nthawi imodzi, makamaka pankhani yowunikira deta ndi ma alamu achitetezo.
Kumbali inayi, opereka chithandizo ayenera kukhala ndi luso lapamwamba pakupanga ndi kutha kuwongolera bwino mtundu ndi tsatanetsatane wa gawo lililonse. Pomanga malo osungiramo zinthu zozizira, pokhapokha ngati ndi nyumba yayikulu yosungiramo zinthu zozizira yomwe imafuna elevator, gawo lomwe limatenga nthawi yayitali nthawi zambiri ndi kusonkhanitsa kapangidwe ka malo osungiramo zinthu zozizira. Kutalika kwa mapanelo osungiramo zinthu zozizira ndi kulondola kwa malo ogwirira ntchito kumatsimikizira mwachindunji kusalala kwa nyumbayo.
Kuphatikiza apo, ngati kapangidwe ka malo osungiramo zinthu sikukugwirizana bwino ndi kukula ndi kulemera kwa zinthu zazikulu monga makina ozizira komanso ma condenser, zingayambitse zopinga pakupanga kapena zoopsa zachitetezo. Izi zimapangitsa kuti opereka chithandizo azimvetsetsa bwino zinthu zokhudzana nazo.
Harbin Dong`an Building Sheets Co., Ltd. ndi kampani yotsogola yopereka njira zosungira zinthu zozizira ku China. Kampaniyo ili ndi njira zamakono zopangira mapanelo osungira zinthu zozizira, zomwe zimatha kuwongolera molondola momwe mapanelo amagwirira ntchito. Nthawi yomweyo, kampaniyo ili ndi luso lalikulu pakupanga malo osungira zinthu zozizira ndipo imatha kukonza zinthu zotsika mtengo malinga ndi zosowa za ogwiritsa ntchito, zomwe zimathandizira kuti ntchito yomanga ikhale yogwira mtima.
