Nyumba yosungiramo zinthu zozizira ndi malo ofunikira kwambiri pa malonda apadziko lonse lapansi. Imaonetsetsa kuti zinthu zomwe zimakhudzidwa ndi kutentha zimakhala zotetezeka. Malo apaderawa amasunga kutentha kochepa. Izi ndizofunikira kwambiri pa chakudya, mankhwala, ndi mankhwala ena. Unyolo wozizira wogwira ntchito bwino umachepetsa kuwonongeka ndi kutayika. Umathandizanso kuti zinthu zikhale zotetezeka komanso zabwino.
Makhalidwe ndi Madera Otentha a Nyumba Yosungiramo Zinthu Zozizira
Nyumba zosungiramo zinthu zozizira zimayendetsedwa ndi malamulo okhwima okhudza kutentha. Ndi nyumba zotetezedwa kwambiri. Zimasunga kutentha kofanana mosasamala kanthu za momwe zinthu zilili kunja. Malo amenewa nthawi zambiri amagawidwa m'malo osiyanasiyana otenthetsera.
Malo Osungirako Zinthu Zozizira: Malo awa amagwira ntchito pakati pa 0°C ndi 10°C. Ndi abwino kwambiri pa zokolola zatsopano, mkaka, ndi mazira.
Kusungirako Zinthu Zozizira: Kutentha kuno nthawi zambiri kumakhala pakati pa -18°C mpaka -25°C. Malo awa ndi oyenera nyama zozizira, nsomba zam'madzi, ndi zakudya zokonzedwa.
Kuzizira Kwambiri/Kutsika Kwambiri: Malo apaderawa amatha kutsika pansi pa -60°C. Ndikofunikira posungira katemera wina ndi zitsanzo zamoyo zamtengo wapatali. Katemera wa COVID-19 amafunika kusungidwa kutentha kotsika mpaka -70°C.
Chotenthetsera nthawi zambiri chimakhala chokhuthalamapanelo a masangwejiKawirikawiri amakhala ma sandwich panels okhala ndi polyurethane kapena PIR ngati zinthu zofunika kwambiri. Ma sandwich panels okhala ndi insulation nthawi zambiri amakhala ndi makulidwe a mamilimita 100 mpaka 200.Mapanelo osungira oziziraali ndi mphamvu yabwino kwambiri yolimbana ndi kutentha. Zotchinga nthunzi nazonso ndizofunikira. Zimaletsa kusamuka kwa chinyezi kulowa m'makoma.
Izi zimaletsa kuzizira ndi kupanga ayezi. Kuteteza pansi kumaletsa kuzizira kwa nthaka. Kuzizira kwa nthaka kumachitika chifukwa cha kuzizira kwa nthaka pansi. Makina omangira ayenera kukhala ndi zida zapadera zogwirira ntchito. Ayeneranso kupirira kuzizira kwambiri.
Machitidwe Osungiramo Zinthu Zozizira ndi Kugwiritsa Ntchito Mphamvu mu Nyumba Yosungiramo Zinthu Zozizira
Makina oziziritsira ndi mtima wa nyumba yosungiramo zinthu zozizira. Mainjiniya amawapanga kuti azigwira ntchito bwino komanso modalirika. Makina odziwika bwino amagwiritsa ntchito ma compressor akuluakulu apakati. Amazungulira ma refrigerant monga ammonia kapena CO₂. Ammonia ndi yothandiza kwambiri, ndipo makina a ammonia amakwaniritsa kuchuluka kwa mphamvu zogwiritsira ntchito mphamvu zopitirira 5.0. Komabe, amafunika njira zokhwima zotetezera. Makina a CO₂ sawononga chilengedwe. Akutchuka kwambiri.
Dongosololi limachotsa kutentha pamalo osungira. Limakwaniritsa izi kudzera mu evaporators ndi air handlers. Kenako dongosololi limakana kutentha kunja kudzera mu condenser. Kugwiritsa ntchito mphamvu ndi ndalama zazikulu zogwirira ntchito. Kusunga kozizira kumawononga pafupifupi 15-20% ya mphamvu yonse yomwe imagwiritsidwa ntchito mu unyolo woperekera chakudya. Mapangidwe amakono amagogomezera kubwezeretsa kutentha. Amagwiritsanso ntchito ma drive osinthasintha pa compressors. Izi zitha kuchepetsa kugwiritsa ntchito mphamvu ndi 30%. Kupanga mphamvu kobwerezabwereza ndikofunikira. Kumaletsa kutayika kwa zinthu panthawi ya kuzima kwa magetsi.
Ubwino ndi Zotsatira Zachuma za Nyumba Yosungiramo Zinthu Zozizira
Malo osungiramo zinthu zozizira amapereka ubwino waukulu pazachuma. Amawonjezera nthawi yosungiramo zinthu zomwe zimatha kuwonongeka, monga zipatso, nsomba zam'madzi, kapena nyama. Izi zimachepetsa kwambiri kutayika kwa chakudya. Bungwe la United Nations likuyerekeza kuti pafupifupi gawo limodzi mwa magawo atatu a chakudya chonse chopangidwa chimatayika kapena kutayika padziko lonse lapansi. Malo abwino oziziritsa amatha kuchepetsa kwambiri kutayika kumeneku. Amalola kuti malonda a padziko lonse lapansi ayende bwino. Zinthu zimatha kuyenda mtunda wautali. Izi zimatsegula misika yatsopano kwa opanga ndi ogula.
Kwa mankhwala, ubwino wake ndi kugwira ntchito bwino kwa mankhwala. Kusunga kutentha kokhazikika kumatsimikizira kuti mankhwalawo amagwira ntchito monga momwe amafunira. Izi ndizofunikira kwambiri pa thanzi la odwala. Kupindula kwachuma pa ndalama zomwe zayikidwa ndi kwakukulu. Kupewa kulephera kamodzi kokha pa katundu wozizira kungapulumutse madola masauzande ambiri. Malowa amaperekanso kukula kwa ntchito. Amathandizira makampani okonza zinthu ndi kukonza zinthu mwapadera. Ndi gawo lofunika kwambiri pa zomangamanga zamakono zokonza zinthu.
Mavuto a Kapangidwe ndi Kumanga
Kumanga nyumba yosungiramo zinthu zozizira kumabweretsa zovuta zapadera zaukadaulo. Kuletsa milatho yotenthetsera ndikofunikira kwambiri pomanga. Mlatho wotenthetsera umalepheretsa kutentha. Umalola kutentha kusamutsidwa mosavuta. Izi zimapangitsa kuti mphamvu itayike komanso kuti nyumbayo ikhale yonyowa. Pansi pake pamafunika chisamaliro chapadera. Mainjiniya ayenera kugwiritsa ntchito kutentha kapena mpweya wokwanira pansi. Izi zimaletsa kuti pansi pa nyumbayo pasamaundane ndi kukulirakulira. Zitseko zake ndi zachangu kwambiri, zotenthetsera. Zimachepetsa mpweya wofunda komanso wonyowa panthawi yokweza katundu.
Ma air lock kapena ma vestibule nthawi zambiri amagwiritsidwa ntchito. Amapanga malo osungira kutentha. Makina owunikira ayeneranso kukhala apadera. Nthawi zambiri amakhala ma LED. Amapereka kutentha kochepa. Kapangidwe kake kayenera kuonetsetsa kuti mpweya umayenda bwino mkati. Izi zimatsimikizira kutentha kofanana m'malo onse. Kulephera kusunga kufanana kungayambitse kuwonongeka ngakhale m'chipinda chozizira. Kumanga nyumba zapaderazi nthawi zambiri kumawononga 50% pa mita imodzi kuposa nyumba yosungiramo zinthu zouma.
Zofunikira pa kasamalidwe
Malo osungiramo zinthu zozizira amathandizira kutsatira malamulo okhwima. Kusunga chakudya kumatsatira miyezo ya HACCP ndi ISO 22000. Malo osungiramo zinthu zamankhwala amakwaniritsa zofunikira za GDP. Advanced Warehouse Management Systems ndi yokhazikika. Amayang'anira zinthu zomwe zili m'sitolo, kayendedwe ka zinthu, ndi kutentha. Masensa opanda zingwe amaikidwa m'malo onse. Amayang'anira kutentha ndi chinyezi nthawi yeniyeni.
Olemba deta amalemba ulendo wonse wa malonda. Izi zimapereka njira yonse yowunikira kuti aone ngati zinthu zikutsatira malamulo. Zolemba za kutentha nthawi zambiri zimasunga deta mphindi zisanu zilizonse. Makina a alamu amayambitsa machenjezo mkati mwa masekondi 30 kuchokera pamene zinthu zasintha. Makina amagetsi osungira amatsimikizira kudalirika. Majenereta a dizilo nthawi zambiri amaphimba 100 peresenti ya katundu wozizira. Kudziyimira pawokha kwa nthawi zonse kumafika maola 48. Ma compressor owonjezera amawonjezera chitetezo. Njirazi zimateteza katundu wamtengo wapatali. Mtengo wazinthu zomwe zili m'mafakitale umatha kupitirira USD 50,000 pa pallet iliyonse. Chifukwa chake, malo osungira ozizira odalirika amachepetsa chiopsezo cha zachuma komanso kuwonongeka kwa malamulo.
