1. Mafiriji madiki anowanzo kukamurwa kuva mhando mbiri: yemukati mhando uye yekunze mhando
(1) Tembiricha uye hunyoro kunze kwekamuri inotonhora: tembiricha iri +35 ° C;hunyoro hunoenderana ne80%.
(2) Iyo tembiricha yakaiswa muimba inotonhora: nyowani-inochengeta imba inotonhora: +5～-5℃;firiji inotonhora imba: -5～-20 ℃;yakadzika tembiricha inotonhora imba: -25 ℃
(3) Tembiricha yekudya ichipinda mukamuri inotonhora: L-level inotonhora imba: +30 °C;D-level uye J-level kamuri inotonhora: +15 °C.
(4) Iyo inobatsira vhoriyamu yekamuri inotonhora yakarongedzwa ingangoita 69% yehuwandu hwezita, uye inowedzerwa neyakagadziriswa chinhu che 0.8 kana uchichengeta michero nemiriwo.
5) Nhamba yekutenga zuva nezuva ndeye 8-10% yehuwandu hunobatsira hwekamuri inotonhora.
2. Muviri wekamuri duku rinotonhora
Kazhinji, kupfapfaidza-pendi yemavara simbi ndiro inoshandiswa sepanera, uye yakasimba polyurethane foam kana yakakwira-density polystyrene inoshandiswa sechinhu chinopisa chekudzivirira.
Kamuri diki inotonhora kazhinji inotora hoko-mhando yekubatanidza kana pa-saiti kupupa uye kugadzirisa zvikamu zvakamisikidzwa mukati memadziro emadziro akadzokororwa, ane kuita kwakanaka kwekuisa chisimbiso uye ari nyore kuunganidza, kupatsanura uye kutakura.Imba diki inotonhora inoshongedzerwa neyepamusoro firiji unit, iyo yekuchengetedza uye midziyo yefiriji yakanyatsoenderana, chiyero chekutonhora chinokurumidza, kuchengetedza simba uye kuchengetedza simba, uye zvese otomatiki mashandiro, kushanda kwakagadzikana uye kwakavimbika.Imba diki yakagara yakagadzirwa inotonhora inoshandiswa zvakanyanya, tembiricha yekamuri inotonhora i5 ° C--23 ° C, uye yakasarudzika yakasarudzika kamuri inotonhora inogona kusvika pazasi -30 ° C, inogona kusangana nezvinodiwa zvekushandisa kwakasiyana uye inokodzera. kushandiswa mumaindasitiri akasiyana.
3. Kusarudzwa kwemidziyo yefriji yekamuri duku inotonhora
Mwoyo wemidziyo diki inotonhora yemufiriji ndiyo unit yefiriji.Iwo anowanzo shandiswa modhi yediki mafiriji mayuniti anoshandisa advanced fluorine muchina wefiriji michina.Kushanda kwefluorine muchina wefiriji michina haina mhedzisiro pane zvakatipoteredza.Iyo refrigerant R22 uye mamwe mafiriji matsva.Fluorine muchina wefiriji michina inowanzo idiki muhukuru, yakaderera muruzha, yakachengeteka uye yakavimbika, yakakwira mune otomatiki, uye inoshandiswa zvakanyanya mumhando dzakasiyana dzekushandisa.Inokodzera midziyo yefiriji inoshandiswa mumafiriji maduku mumisha.
Iko kusanganiswa kwemafiriji uye condensers nemimwe midziyo inoshandiswa mumakamuri maduku anotonhora inowanzonzi zvikamu zvefriji.Zvikwata zvefiriji zvakakamurwa kuva zvikamu zvakanyoroveswa nemvura uye mhepo inotonhorera.Iyo air-yakatonhodzwa unit ndiyo yekutanga sarudzo yekamuri diki inotonhora, ine zvakanakira zvekureruka, compactness, nyore kuisirwa, kushanda kuri nyore, uye kushomeka kwemidziyo.Iyi mhando yemidziyo yefiriji zvakare iri nyore kuona.
Firiji yefriji yefriji ndiyo mwoyo wemidziyo yefriji.Common compression refrigerators yakakamurwa kuva yakavhurika mhando, semi-yakavharwa mhando uye yakazara yakavharwa mhando.Iyo compressor yakavharwa zvizere ine saizi diki, yakaderera ruzha, yakaderera mashandisiro emagetsi, yakanyanya kunaka uye kuchengetedza simba.Ndiyo yekutanga sarudzo yemafiriji madiki.Iri mhepo inotonhorera refrigeration unit inonyanya kuumbwa necompressor yakavharwa zvakakwana.Inogona kugadzirwa kuita fomu seyakapatsanurwa air conditioner uye yakaiswa pamadziro.
Parizvino, yakanakisa-yakavharwa yakazara firiji compressors pamusika inovimbika maererano nemhando yemidziyo yefiriji inounzwa kubva munyika kana kubva kuSino-yekunze kudyidzana, asi kukosha kwacho kunopfuura 50% yakakwirira kupfuura iyo yemidziyo yemufiriji yemumba.
4. Mapeji ekugadzira ekamuri diki inotonhora
Tembiricha yemukamuri inotonhora iri pasi pe0 madhigirii (-16 madhigirii), uye kamuri diki rakagara rakagadzirirwa inotonhora inoda kudzoserwa ne10 # chiteshi simbi pasi (pasi pebhodhi rekuchengetera), kuitira kuti igone kufefeterwa.Kamuri diki inotonhora, tembiricha mukamuri inotonhora i5 ~ -25 madhigirii, iyo inotonhora kamuri bhodhi inogona zvakananga kubata pasi, asi pasi rinofanira kunge rakati sandara.Kana nzvimbo yakakwirira ichidikanwa, mitsetse yemapuranga inogona kurongwa pasi pekamuri inotonhora kudzivirira kufefetera kuti kuwedzere kufefetera;chiteshi chesimbi chinogonawo kurongeka pasi pekamuri inotonhora kuti iwedzere kufefetera.
5. Cold room engineering dhizaini uye yekuisa chikumbiro
Mumakore achangopfuura, kuvakwa kwemapurojekiti ekamuri inotonhora kwakakura nekukurumidza uye nekukurumidza, uye kujairana kwemunhu wese nekamuri inotonhora kwakawedzera kudzika.Zvinofungidzirwa kubva kuhutano hwekuvaka kuti kusarudzwa kwemarudzi akasiyana-siyana emidziyo yekamuri inotonhora iri kuwedzera kukura.Pane nzira mbiri dzekuvaka dzakajairwa dzemapurojekiti ekamuri inotonhora, imwe ipurojekiti yekamuri yekutonhora, uye imwe yacho ipurojekiti yekamuri inotonhora.
Parizvino, imba inotonhora yakagara yakasarudzika inonyanya kusarudza iyo polyurethane yekuchengetera muviri: kureva kuti, imba inotonhora bhodhi inogadzirwa nepolyurethane rigid foam (PU) sesandwich, uye zvinhu zvesimbi zvakaita seplastic-yakavharwa simbi ndiro inoshandiswa sepamusoro. layer, kuitira kuti iyo inotonhora kamuri bhodhi ive yakanaka yekupisa yekuvharisa kuita uye kuita kwakanakisa.Simba remuchina rinobatanidza nzira yose.Iine maitiro ehupenyu hurefu hwekudzivirira kupisa, kugadzirisa kuri nyore, mutengo wakaderera, simba rakawanda uye uremu huremu.Mazhinji emapurojekiti ekamuri inotonhora anoshandisa PU polyurethane pfapfaidzo foam seyo inopisa bhodhi.
Izvo zvakakosha zvakanyanya kana michina yefiriji yekamuri inotonhora inonzwisisika.Izvi zvinodaro nekuti iyo firiji unit ine inonzwisisika uye yakavimbika kuita haigone chete kusangana neiyo firiji kugona kwekamuri inotonhora uye tekinoroji zvinodiwa zvekamuri inotonhora inodiwa nechigadzirwa, asi zvakare chengetedza simba uye kuderedza chiyero chekutadza.Parizvino, mamwe makambani uye vanhu vanoda kuvaka makamuri anotonhora vanoteedzera kukosha kwakaderera, vachiregeredza kana kuenzanisa kwemidziyo yekamuri inotonhora kune musoro, zvichikonzera kutadza kuwana mhedzisiro yekutonhodza mushure mekushandisa.Kugadziriswa kunonzwisisika uye kuenzanisa midziyo yefiriji yemapurojekiti ekamuri inotonhora inogona kuwedzera mari kana uchivaka imba inotonhora, asi nekufamba kwenguva, inochengetedza mari yakawanda uye kushanda nesimba.
Iyo mushure mekutengesa sevhisi yemidziyo yekamuri inotonhora yakakoshawo, uye kushanda uye kugadzirisa kwemidziyo yekamuri inotonhora uye masevhisi ehunyanzvi akakosha zvakaenzana.Mabhizinesi ekuvaka imba yekuchengetera anofanirwa kuongorora zvakasiyana-siyana mumakore ekutanga ekuvaka imba inotonhora, teerera kune mamwe mabhizinesi ekugadzika kwemidziyo yefiriji yekamuri inotonhora, uye pakupedzisira sarudza hurongwa hwekamuri inotonhora.Gadzira yako wega imba inotonhora ine yakakwira yekutanga nzvimbo uye chiyero chepamusoro, uye edza kuwana zvakakunakira iwe pachako.
