1. Mafiriji ang'onoang'ono amagawidwa m'mitundu iwiri: mtundu wamkati ndi wakunja
(1) Kutentha ndi chinyezi kunja kwa chipinda chozizira: kutentha ndi +35 ° C;chinyezi chachibale ndi 80%.
(2) Kutentha kokhazikika m'chipinda chozizira: chipinda chozizira chosungira mwatsopano: +5～-5 ℃;chipinda chozizira chozizira: -5～-20 ℃;otsika kutentha chipinda ozizira: -25 ℃
(3) Kutentha kwa chakudya cholowa m’chipinda chozizira: Chipinda chozizira cha L-level: +30 °C;D-level ndi J-level chipinda chozizira: +15 °C.
(4) Voliyumu yothandiza ya chipinda chozizira chodzaza ndi pafupifupi 69% ya voliyumu yodziwika bwino, ndipo imachulukitsidwa ndi kuwongolera kwa 0,8 posunga zipatso ndi ndiwo zamasamba.
5) Kugula kwatsiku ndi tsiku ndi 8-10% ya voliyumu yothandiza ya chipinda chozizira.
2. Thupi la chipinda chozizira chaching'ono
Nthawi zambiri, mbale yachitsulo yopaka utoto imagwiritsidwa ntchito ngati gulu, ndipo thovu lolimba la polyurethane kapena polystyrene yolimba kwambiri imagwiritsidwa ntchito ngati zida zotenthetsera.
Chipinda chozizira chaching'ono nthawi zambiri chimagwiritsa ntchito kulumikizana kwamtundu wa mbedza kapena kuchita thovu pamalopo ndikukonza magawo omwe aphatikizidwa mkati mwa khoma lokonzedwanso, lomwe limakhala ndi ntchito yabwino yosindikiza komanso yosavuta kusonkhanitsa, kupasuka ndi kunyamula.Chipinda chaching'ono chozizira chimakhala ndi chipinda chapamwamba cha firiji, mphamvu yosungiramo zinthu zosungirako ndi zipangizo za firiji zimagwirizana bwino, kuzizira kumakhala kofulumira, kupulumutsa mphamvu ndi kupulumutsa mphamvu, ndi ntchito zonse zokha, ntchitoyo ndi yokhazikika komanso yodalirika.Chipinda chozizira chaching'ono chopangidwa kale chimagwiritsidwa ntchito kwambiri, kutentha kwa chipinda chozizira ndi 5 ° C--23 ° C, ndipo chipinda chozizira chapadera chokhazikika chimatha kufika pansi -30 ° C, chomwe chingakwaniritse zosowa za ntchito zosiyanasiyana ndipo ndichoyenera. ntchito m'mafakitale osiyanasiyana.
3. Kusankha zipangizo za firiji kwa chipinda chaching'ono chozizira
Mtima wa zida zazing'ono zozizira zozizira ndi firiji.Zitsanzo zomwe zimagwiritsidwa ntchito kwambiri pazigawo zing'onozing'ono za firiji zimagwiritsa ntchito zida zapamwamba zamakina a fluorine firiji.Kugwiritsa ntchito zida zopangira firiji zamakina a fluorine sikukhudza chilengedwe.Refrigerant R22 ndi mafiriji ena atsopano.Zida zopangira firiji zamakina a fluorine nthawi zambiri zimakhala zazing'ono, phokoso lochepa, lotetezeka komanso lodalirika, lokwera kwambiri, ndipo limagwiritsidwa ntchito kwambiri pamagwiritsidwe osiyanasiyana.Ndizoyenera zida za firiji zomwe zimagwiritsidwa ntchito m'mafiriji ang'onoang'ono m'midzi.
Kuphatikiza mafiriji ndi ma condensers ndi zida zina zomwe zimagwiritsidwa ntchito m'zipinda zazing'ono zozizira nthawi zambiri zimatchedwa magawo a refrigeration.Magawo a firiji amagawidwa m'magawo oziziritsa madzi ndi mayunitsi a mpweya.Chipinda choziziritsa mpweya ndicho kusankha koyamba kwa chipinda chozizira chaching'ono, chomwe chili ndi ubwino wophweka, kugwirizanitsa, kuyika kosavuta, ntchito yabwino, ndi zipangizo zochepetsetsa.Zida zamafiriji zamtunduwu ndizosavuta kuziwona.
Firiji ya firiji unit ndi mtima wa firiji zipangizo.Mafiriji ophatikizika wamba amagawidwa kukhala mtundu wotseguka, mtundu wotsekedwa komanso wotsekedwa kwathunthu.Compressor yotsekedwa kwathunthu imakhala ndi kukula kochepa, phokoso lochepa, kugwiritsa ntchito mphamvu zochepa, kuyendetsa bwino kwambiri komanso kupulumutsa mphamvu.Ndilo kusankha koyamba kwa mafiriji ang'onoang'ono.Ndi gawo la firiji loziziritsidwa ndi mpweya lomwe limapangidwa ndi kompresa yotsekedwa kwathunthu.Ikhoza kupangidwa kukhala mawonekedwe ngati mpweya wogawanika wogawanika ndikuyika pakhoma.
Pakalipano, ma compressor otsekedwa bwino kwambiri a firiji pamsika ndi odalirika potengera mtundu wa zida zamafiriji zomwe zimatumizidwa kuchokera kudziko kapena kuchokera ku mgwirizano wa Sino-akunja, koma mtengo wake ndi woposa 50% kuposa zida zamafiriji apanyumba.
4. Malo opangira chipinda chaching'ono chozizira
Kutentha kwachipinda chozizira kumakhala pansi pa 0 madigiri (-16 madigiri), ndipo kachipinda kakang'ono kozizira kokhazikika kamayenera kubwezeredwa ndi chitsulo cha 10 # pansi (pansi pa bolodi yosungiramo), kuti chizitha kutulutsa mpweya wabwino mwachilengedwe.Chipinda chozizira chaching'ono, kutentha m'chipinda chozizira ndi madigiri 5 ~ -25, bolodi la chipinda chozizira limatha kukhudza pansi, koma pansi payenera kukhala lathyathyathya.Ngati pakufunika malo okwera, matabwa amatha kukonzedwa pansi pa chipinda chozizira kuti ateteze mpweya wabwino kuti upititse mpweya wabwino;Chitsulo cha njira chimatha kukonzedwanso pansi pa chipinda chozizira kuti chiwonjezere mpweya wabwino.
5. Cold room engineering engineering design ndi kuyikapo
M'zaka zaposachedwa, ntchito yomanga chipinda chozizira yakula mofulumira komanso mofulumira, ndipo kudziwika kwa aliyense ndi chipinda chozizira kwakhala kozama kwambiri.Zimaganiziridwa kuchokera ku khalidwe la zomangamanga kuti kusankha kwa mitundu yosiyanasiyana ya zipangizo zozizira kumakhala kokhwima.Pali njira ziwiri zomangira zomwe zimagwiritsidwa ntchito pazipinda zozizira, imodzi ndi yopangira chipinda chozizira, ndipo ina ndi projekiti yachipinda chozizira.
Pakalipano, chipinda chozizira chokonzedweratu chimasankha thupi losungiramo polyurethane: ndiye kuti, chipinda chozizira chimapangidwa ndi thovu lolimba la polyurethane (PU) monga sangweji, ndipo zitsulo monga zitsulo zopangidwa ndi pulasitiki zimagwiritsidwa ntchito ngati pamwamba. wosanjikiza, kuti bolodi la chipinda chozizira likhale ndi ntchito yabwino yotchinjiriza kutentha komanso magwiridwe antchito abwino kwambiri.Mphamvu ya makina imagwirizanitsa njira yonse.Ili ndi mawonekedwe a moyo wautali wotsekereza kutentha, kukonza kosavuta, mtengo wotsika, mphamvu yayikulu komanso kulemera kopepuka.Ma projekiti ambiri azipinda zozizira za anthu amagwiritsa ntchito thovu la PU polyurethane ngati bolodi lotenthetsera.
Ndikofunikira kwambiri ngati zida za firiji za chipinda chozizira ndizoyenera.Izi zili choncho chifukwa chipinda cha firiji chokhala ndi ntchito yodalirika komanso yodalirika sichikhoza kukwaniritsa mphamvu ya firiji ya chipinda chozizira komanso zofunikira zaumisiri m'chipinda chozizira chomwe chimafunidwa ndi mankhwala, komanso kupulumutsa mphamvu ndikuchepetsa kulephera.Pakali pano, makampani ena ndi anthu omwe akufuna kumanga zipinda zozizira amatsata mwachimbulimbuli zamtengo wapatali, kunyalanyaza ngati kufananitsa zipangizo za chipinda chozizira kuli koyenera, zomwe zimachititsa kuti alephere kukwaniritsa zotsatira zoziziritsa atazigwiritsa ntchito.Kukonzekera koyenera ndi zipangizo zofananira ndi firiji zamapulojekiti a chipinda chozizira kungapangitse ndalama pomanga chipinda chozizira, koma m'kupita kwa nthawi, zimapulumutsa ndalama zambiri ndi khama.
Ntchito yogulitsa pambuyo pogulitsa zida zachipinda chozizira ndiyofunikanso kwambiri, ndipo kugwira ntchito ndi kukonza zida zachipinda chozizira ndi ntchito zaukadaulo ndizofunikiranso.Mabizinesi ambiri omanga nyumba zosungiramo katundu ayenera kuyang'ana mbali zosiyanasiyana m'zaka zoyambirira zomanga chipinda chozizira, kumvera malingaliro a mabizinesi ena pakukhazikitsa zida zoziziritsira m'chipinda chozizira, ndipo pamapeto pake adziwe dongosolo lothandizira lachipinda chozizira.Konzani chipinda chanu chozizira chokhala ndi poyambira komanso chokwera kwambiri, ndipo yesetsani kupeza phindu labwino kwambiri kwa inu nokha.
