Malo ozizira ndi malo osungiramo zinthu omwe amagwiritsa ntchito malo ozizira kuti apange chinyezi choyenera komanso kutentha kochepa. Amatchedwanso ozizira yosungirako. Ndi malo omwe zinthu zimakonzedwa ndikusungidwa. Itha kuchotsa chikoka cha nyengo ndikutalikitsa nthawi yosungira zinthu zosiyanasiyana kuti ziwongolere msika.
Cholinga cha firiji yosungirako ozizira:
Ntchito mfundo ya refrigeration dongosolo Cholinga cha firiji ndi ntchito njira kusamutsa kutentha kwa ophatikizana ozizira yosungirako chinthu kwa yozungulira sing'anga madzi kapena mpweya, kuti kutentha kwa utakhazikika chinthu adatchithisira pansi kutentha yozungulira ndi anakhalabe mkati mwa nthawi. kutentha.
Cold storage refrigeration system:
Dongosolo la refrigeration lathunthu la nthunzi liyenera kuphatikizirapo makina ozungulira a refrigerant, mafuta opaka mafuta, defrosting system, makina oziziritsira madzi ozungulira ndi ma refrigerant circulation system, etc.
Chifukwa cha zovuta komanso ukatswiri wa firiji yosungirako kuzizira, zolakwika zina zodziwika bwino zidzachitika panthawi ya opaleshoniyo.
| Kulephera kozizira kosungirako kozizira | Chifukwa
|
| Kutaya kwa refrigerant | Pambuyo pazitsulo za refrigerant mu dongosolo, mphamvu yoziziritsa imakhala yosakwanira, kuyamwa ndi kutulutsa mpweya kumakhala kochepa, ndipo "kugwedeza" kwapakatikati kwa mpweya kumamveka kwakukulu kuposa nthawi zonse kumamveka pa valve yowonjezera. Palibe chisanu kapena chisanu choyandama pa evaporator. Ngati dzenje la valve yowonjezera likukulitsidwa, kukakamiza koyamwa sikumasintha kwambiri. Pambuyo pozimitsa, kupanikizika kofanana mu dongosolo nthawi zambiri kumakhala kotsika poyerekeza ndi kutentha komwe kumayenderana ndi kutentha komweko.
|
| Kulipiritsa kwambiri refrigerant pambuyo pokonza | Kuchuluka kwa refrigerant yomwe imayikidwa mufiriji pambuyo pokonza kupitirira mphamvu ya dongosolo, ndipo refrigerant idzatenga voliyumu ina ya condenser, kuchepetsa kutentha kwa kutentha, ndi kuchepetsa kuzizira. Mphamvu yokoka ndi utsi nthawi zambiri imakhala yokwera kuposa kuthamanga kwanthawi zonse, evaporator simazizira kwambiri, ndipo kuziziritsa m'nyumba yosungiramo zinthu kumachedwa. |
| Muli mpweya mufiriji | Mpweya wa firiji umachepetsa mphamvu ya firiji. Chochitika chodziwikiratu ndi chakuti kuyamwa ndi kutulutsa mphamvu kumawonjezeka (koma kuthamanga kwa mpweya sikunapitirire mtengo wake), ndipo kutulutsa kwa compressor kupita ku condenser inlet Kutentha kumawonjezeka kwambiri. Chifukwa cha kukhalapo kwa mpweya mu dongosolo, kuthamanga kwa mpweya ndi kutentha kwa mpweya kumawonjezeka. |
| Kutsika kwa compressor | Kutsika kocheperako kwa kompresa ya firiji kumatanthawuza kuti kuchuluka kwenikweni kwa mpweya kumachepa ndipo mphamvu ya firiji imachepa molingana ndi momwe zinthu zimagwirira ntchito sizisintha. Izi zimachitika makamaka mu compressor zomwe zakhala zikugwiritsidwa ntchito kwa nthawi yayitali. Kuvala ndi kung'ambika kwa compressor ndi kwakukulu, chilolezo chofananira cha chigawo chilichonse ndi chachikulu, ndipo ntchito yosindikiza ya valve ya mpweya imachepetsedwa, zomwe zimapangitsa kuchepa kwa mphamvu yeniyeni yotulutsa mpweya. |
| Chichisanu pamwamba pa evaporator ndi wandiweyani kwambiri | Kugwiritsa ntchito nthawi yayitali kwa evaporator yozizira kosungirako kuyenera kuchepetsedwa pafupipafupi. Ngati sichinaphwanyidwe, chisanu chowunjika papaipi ya evaporator chidzawunjikana ndikukhuthala. Pamene payipi yonseyo itakulungidwa mu ayezi wowonekera, Idzakhudza kwambiri kutentha kwa kutentha, kuchititsa kuti kutentha kwa nyumba yosungiramo katundu kugwere pansi pa mlingo wofunikira. |
| Pali mafuta otenthedwa mufiriji mupaipi ya evaporator | Panthawi ya firiji, mafuta ena osungidwa mufiriji amakhalabe mupaipi ya evaporator. Pambuyo pakugwiritsa ntchito nthawi yayitali, ngati pali mafuta ambiri otsalira mu evaporator, zimakhudza kwambiri kutentha kwake. , chodabwitsa cha kuzizira kosazizira kumachitika. |
| Firiji dongosolo si yosalala | chifukwa cha kusayeretsa bwino kwa firiji, pakatha nthawi yogwiritsira ntchito, dothi limachulukana pang'onopang'ono mu fyuluta, ndipo ma meshes ena amatsekedwa, zomwe zimachepetsa kutuluka kwa firiji ndikusokoneza kuzizira. Mu dongosolo, valavu yowonjezera ndi fyuluta pa doko loyamwa la compressor imatsekedwa pang'ono. |
| Bowo la valavu yokulirapo limawumitsidwa ndikutsekedwa | zigawo zikuluzikulu mu firiji dongosolo si zouma bwino, vacuuming wa dongosolo lonse si wathunthu, ndipo chinyontho cha refrigerant kuposa muyezo. |
| Kutsekeka kodetsa pazithunzi zosefera za valve yokulitsa |
