Malo osungira zinthu ozizira ndi malo osungiramo zinthu omwe amagwiritsa ntchito malo ozizira kuti apange chinyezi choyenera komanso kutentha kochepa. Amadziwikanso kuti malo osungira zinthu ozizira. Ndi malo omwe zinthu zimakonzedwa ndikusungidwa. Amatha kuchotsa mphamvu ya nyengo ndikuwonjezera nthawi yosungira zinthu zosiyanasiyana kuti azilamulira kupezeka kwa zinthu pamsika.
Cholinga cha makina osungiramo zinthu zoziziritsa kukhosi:
Mfundo yogwirira ntchito ya makina oziziritsira Cholinga cha makina oziziritsira ndikugwiritsa ntchito njira zina zosamutsira kutentha kwa chinthu chosungiramo chozizira pamodzi kupita ku madzi kapena mpweya wozungulira, kuti kutentha kwa chinthu choziziritsira kuchepetse kutentha kozungulira ndikusungidwa mkati mwa nthawi inayake.
Zipangidwe za dongosolo la firiji losungiramo zinthu zozizira:
Dongosolo lonse loziziritsira mpweya liyenera kuphatikizapo njira yoziziritsira mpweya m'firiji, njira yothira mafuta, njira yosungunula madzi, njira yoziziritsira madzi ndi njira yoziziritsira mpweya m'firiji, ndi zina zotero.
Chifukwa cha zovuta komanso ukatswiri wa makina oziziritsira m'malo osungiramo zinthu zozizira, zolakwika zina zofala zidzachitika nthawi yonse yogwira ntchito.
| Kulephera kwa makina oziziritsira ozizira | Choyambitsa
|
| Kutuluka kwa madzi mufiriji | Pambuyo poti refrigerant yatuluka mu dongosolo, mphamvu yoziziritsira imakhala yosakwanira, mphamvu yokoka ndi kutulutsa mpweya imakhala yochepa, ndipo phokoso la mpweya wotuluka nthawi ndi nthawi limamveka pa valavu yowonjezera. Palibe chisanu kapena chisanu choyandama pa evaporator. Ngati dzenje la valavu yowonjezera lakulitsidwa, mphamvu yokoka mpweya sikusintha kwambiri. Pambuyo potseka, mphamvu yofanana mu dongosolo nthawi zambiri imakhala yotsika kuposa mphamvu yokwanira yofanana ndi kutentha komweko.
|
| Kuchajitsa kwambiri firiji pambuyo pokonza | Kuchuluka kwa chotenthetsera chomwe chimayikidwa mu makina oziziritsira pambuyo pokonza kumaposa mphamvu ya makinawo, ndipo chotenthetseracho chimakhala ndi voliyumu inayake ya chotenthetsera, kuchepetsa malo otayira kutentha, ndikuchepetsa mphamvu yoziziritsira. Kuthamanga kwa mpweya ndi kupopera mpweya nthawi zambiri kumakhala kokwera kuposa mphamvu yachibadwa, chotenthetseracho sichimaundana bwino, ndipo kuzizira m'nyumba yosungiramo zinthu kumakhala pang'onopang'ono. |
| Pali mpweya mu makina oziziritsira | Mpweya womwe uli mu makina oziziritsira mpweya umachepetsa mphamvu ya makina oziziritsira mpweya. Chodziwikiratu n'chakuti mphamvu zokoka mpweya ndi utsi zimawonjezeka (koma mphamvu ya utsi siinapitirire mtengo wovomerezeka), ndipo njira yotulutsira mpweya ku condenser inlet Kutentha kumawonjezeka kwambiri. Chifukwa cha kukhalapo kwa mpweya mu makinawo, mphamvu ya utsi ndi kutentha kwa utsi kumawonjezeka. |
| Kugwiritsa ntchito bwino kwa compressor pang'ono | Kugwira ntchito kochepa kwa compressor yoziziritsa kumatanthauza kuti kuchuluka kwenikweni kwa utsi kumachepa ndipo mphamvu ya firiji imachepa moyenerera pamene mikhalidwe yogwirira ntchito isasinthe. Izi zimachitika makamaka mu ma compressor omwe akhala akugwiritsidwa ntchito kwa nthawi yayitali. Kuwonongeka ndi kung'ambika kwa ma compressor ndi kwakukulu, malo ofanana a gawo lililonse ndi akulu, ndipo magwiridwe antchito otseka mpweya amachepa, zomwe zimapangitsa kuti kuchuluka kwenikweni kwa utsi kuchepe. |
| Chipale chofewa pamwamba pa evaporator ndi chokhuthala kwambiri | Kugwiritsa ntchito nthawi yayitali kwa evaporator yosungiramo zinthu zozizira kuyenera kusungunuka nthawi zonse. Ngati sikusungunuka, wosanjikiza wozizira pa payipi ya evaporator udzasonkhanitsidwa ndikukhuthala. Pamene payipi yonse yakulungidwa mu wosanjikiza wowonekera bwino wa ayezi, zidzakhudza kwambiri kusamutsa kutentha, zomwe zimapangitsa kuti kutentha m'nyumba yosungiramo zinthu kukhale pansi pa mulingo wofunikira. |
| Pali mafuta osungidwa mufiriji mu evaporator payipi | Pa nthawi yoziziritsa, mafuta ena osungidwa mufiriji amakhalabe mu evaporator payipi. Pambuyo pa nthawi yayitali yogwiritsidwa ntchito, ngati pali mafuta ambiri otsala mu evaporator, izi zimakhudza kwambiri momwe kutentha kwake kumayendera. , vuto la kuzizira koyipa limachitika. |
| Dongosolo loziziritsira silili bwino | Chifukwa cha kusatsuka bwino kwa makina oziziritsira, pambuyo pa nthawi yogwiritsidwa ntchito, dothi limasonkhana pang'onopang'ono mu fyuluta, ndipo ma meshes ena amatsekedwa, zomwe zimachepetsa kuyenda kwa refrigerant ndikukhudza kuzizira. Mu makinawo, valavu yokulitsa ndi fyuluta yomwe ili pa doko loyamwa la compressor nazonso zimatsekedwa pang'ono. |
| Bowo la valavu yokulirapo lazizira ndipo latsekeka | Zigawo zazikulu mu makina oziziritsira sizinaume bwino, kutsuka kwa makina onse sikunamalizidwe, ndipo chinyezi cha mu firiji chimaposa muyezo. |
| Kutsekeka kwauve pa chinsalu chosefera cha valavu yowonjezera |
