Thechowumitsira mpweya mufirijindi chowumitsira mpweya chowumitsira mpweya chomwe chimagwiritsa ntchito mfundo zakuthupi kuzizira chinyontho chomwe chili mumlengalenga pansi pa mame, ndikuchiyika kukhala madzi amadzimadzi kuchokera mumpweya woponderezedwa ndikuchitulutsa. Chifukwa cha kuzizira kwa madzi, kutentha kwa mame kumatha kuyandikira madigiri 0. M'malo mwake, kutentha kwa mame a chowumitsira bwino chowumitsira madzi kumatha kufikira madigiri 10.
Malingana ndi kusiyana pakati pa osinthanitsa kutentha kwazowumitsa mpweya mufiriji, pakali pano pali mitundu iwiri ya zowumitsira mpweya zokhala ndi ma chubu-fin heat exchanger ndi zotenthetsera zamtundu wa mbale (zomwe zimatchedwa kusinthanitsa mbale) pamsika. Chifukwa chaukadaulo wake wokhwima, kapangidwe kake, kutentha kwambiri, komanso kusakhala ndi kuipitsidwa kwachiwiri, chowumitsira mpweya chotenthetsera chakhala gawo lalikulu pamsika wowumitsa mpweya. Komabe, pali zovuta zambiri pakupanga ndi kugwiritsa ntchito chowotcha chakale cha chubu-fin. Kuchita kwakukulu m'mbali zotsatirazi:
1. Voliyumu yayikulu:
Chubu-fin heat exchanger nthawi zambiri imakhala ndi mawonekedwe opingasa a cylindrical. Kuti mugwirizane ndi mawonekedwe a kutentha kwa kutentha, mapangidwe onse a firiji ndi kuyanika makina amatha kutsata makina opangira kutentha. Choncho, makina onse ndi ochuluka, koma malo amkati alibe kanthu. , Makamaka pazida zapakatikati ndi zazikulu, 2/3 ya danga mkati mwa makina onse ndi ochulukirapo, motero kuwononga malo osafunikira.
2. Kapangidwe Kamodzi:
The chubu-zipsepse kutentha exchanger zambiri utenga kamangidwe mmodzi ndi mmodzi, ndiko kuti, lolingana processing mphamvu mpweya chowumitsira limafanana ndi lolingana processing mphamvu kutentha exchanger, zomwe zimabweretsa zofooka mu ndondomeko kupanga ndipo sangathe flexibly ntchito osakaniza. Njira zogwiritsira ntchito chowotcha chofananacho kuti mupange zowumitsira mpweya zomwe zimakhala ndi mphamvu zosiyanasiyana zopangira, zomwe zingapangitse kuti pakhale kuchuluka kwazinthu zopangira.
3. Avereji kutentha kuwombola bwino
Kutentha kwapang'onopang'ono kwa chubu-fin heat exchanger nthawi zambiri kumakhala pafupifupi 85%, kotero ndikofunikira kukwaniritsa kutentha kwabwino. firiji mphamvu, motero kumawonjezera mtengo wa dongosolo ndi kugwiritsa ntchito mphamvu.
4. Mpweya thovu mu chubu-zipsepse kutentha exchanger
Mapangidwe a zipsepse za sikweya ndi chipolopolo chozungulira cha chubu-fin heat exchanger zimasiya malo osasinthana ndi kutentha munjira iliyonse, zomwe zimapangitsa kuti mpweya ukhale wophulika. Zopindika za evaporator zimalola mpweya wina woponderezedwa kutuluka popanda kusinthana kutentha. Izi zimachepetsa mame a gasi, ndipo kuonjezera mphamvu yozizirira sikuthetsa vutoli. Chifukwa chake, kupanikizika kwa mame a chubu-fin freeze dryer nthawi zambiri kumakhala kupitirira 10°C, komwe sikungafike pa 2°C.
5. Kusawonongeka kwa dzimbiri
Zotenthetsera ma chubu nthawi zambiri zimapangidwa ndi machubu amkuwa ndi zipsepse za aluminiyamu, ndipo njira yomwe amalowera ndi mpweya wamba woponderezedwa komanso mpweya wosawononga. Akagwiritsidwa ntchito pazochitika zina zapadera, monga zowumitsira firiji zam'madzi, kuziziritsa gasi wapadera ndi kuyanika Makina, ndi zina zotero, zimakhala zosavuta kuzimitsa, zomwe zimafupikitsa moyo wautumiki, kapena sizingagwiritsidwe ntchito nkomwe.
Poganizira za mawonekedwe a chubu-fin chotenthetsera chomwe chatchulidwa pamwambapa, chowotcha chotenthetsera mbale chimatha kupanga zophophonya izi. Kufotokozera kwenikweni ndi motere:
1. Kapangidwe kakang'ono ndi kukula kochepa
Chowotcha kutentha kwa mbale chimakhala ndi mawonekedwe apakati ndipo chimakhala ndi malo ochepa. Ikhoza kuphatikizidwa mosavuta ndi zigawo za firiji mu zipangizo popanda kutaya malo ochulukirapo.
2. Chitsanzocho ndi chosinthika komanso chosinthika
Chowotcha chotenthetsera mbale chimatha kusonkhanitsidwa m'njira yofananira, ndiye kuti, chimatha kuphatikizidwa mumayendedwe ofunikira munjira ya 1 + 1 = 2, yomwe imapangitsa kapangidwe ka makina onse kukhala osinthika komanso osinthika, ndipo amatha kuwongolera bwino. ndi yaiwisi kufufuza.
3. Kutentha kwakukulu kwa kutentha
Njira yoyendetsera mbale yosinthira kutentha ndi yaying'ono, zipsepse za mbale zimakhala zosinthika, ndipo kusintha kwagawo kumakhala kovuta. Mbale yaing'ono imatha kupeza malo akuluakulu osinthanitsa kutentha, ndipo kayendetsedwe ka kayendedwe ka madzi ndi kayendedwe ka madzimadzi kumasinthidwa nthawi zonse, zomwe zimawonjezera kuthamanga kwa madzi. Zosokoneza, kotero zimatha kufikira chipwirikiti pakuyenda kochepa kwambiri. Mu chotenthetsera chipolopolo ndi chubu, madzi awiriwa amayenda mbali ya chubu ndi mbali ya chipolopolo motsatana. Nthawi zambiri, kutuluka kwake kumakhala kodutsa, ndipo ma logarithmic avareji ya kutentha kwapakati ndi kocheperako. , Ndipo zosinthira kutentha kwa mbale nthawi zambiri zimakhala zofananira kapena zotsutsana, ndipo kuwongolera kokwanira kumakhala pafupifupi 0,95. Kuonjezera apo, kutuluka kwa madzi ozizira ndi otentha mu mbale yowotcha kutentha kumafanana ndi kutentha kwa kutentha popanda kudutsa, kupanga mbale yotentha yotentha Kusiyanitsa kwa kutentha kumapeto kwa kutentha kwa kutentha kumakhala kochepa, komwe kungakhale kochepa kuposa 1. °C. Chifukwa chake, kupanikizika kwa mame a chowumitsira firiji pogwiritsa ntchito chosinthira kutentha kwa mbale kumatha kutsika mpaka 2 ° C.
4. Palibe mbali yakufa ya kusinthana kwa kutentha, makamaka kukwaniritsa 100% kutentha kutentha
Chifukwa cha njira yake yapadera, chosinthira kutentha kwa mbale chimapangitsa kuti sing'anga yosinthira kutentha igwirizane bwino ndi mbale popanda kutentha kosinthana ndi ngodya zakufa, popanda mabowo okhetsa, komanso kutayikira kwa mpweya. Choncho, mpweya woponderezedwa ukhoza kukwaniritsa kutentha kwa 100%. Onetsetsani kukhazikika kwa mame a chinthu chomalizidwa.
5. Good dzimbiri kukana
Chojambulira kutentha kwa mbale chimapangidwa ndi aluminium alloy kapena chitsulo chosapanga dzimbiri, chomwe chimakhala ndi kukana kwa dzimbiri ndipo chimatha kupewanso kuipitsidwa kwachiwiri kwa mpweya woponderezedwa. Chifukwa chake, zitha kusinthidwa ku zochitika zapadera zosiyanasiyana, kuphatikiza zombo zapamadzi, zokhala ndi mpweya wowononga Mafakitale amankhwala, komanso mafakitale okhwima kwambiri azakudya ndi mankhwala.
Kuphatikiza makhalidwe pamwamba, mbale kutentha exchanger ali ndi ubwino wosagonjetseka chubu ndi fin kutentha exchanger. Poyerekeza ndi chubu ndi fin kutentha exchanger, mbale kutentha exchanger akhoza kupulumutsa 30% pansi pa mphamvu yomweyo processing. Choncho, kasinthidwe ka firiji yamakina onse amatha kuchepetsedwa ndi 30%, ndipo kugwiritsa ntchito mphamvu kungathenso kuchepetsedwa ndi 30%. Voliyumu ya makina onse amathanso kuchepetsedwa ndi 30%.
Chiwonetsero chaposachedwa kwambiri chosinthira mbale chosinthira mufiriji chowumitsira mpweya
