Kapangidwe ka malo osungiramo zinthu zozizira kamagawidwa m'magawo asanu: chipinda chosungiramo zinthu zozizira, bolodi losungiramo zinthu zozizira (kuphatikiza chitseko chosungiramo zinthu zozizira), chotenthetsera madzi, bokosi logawa, chitoliro cha mkuwa.
Malo osungira ozizira
1. Tiyeni tikambirane za bolodi losungiramo zinthu zozizira kaye:
Bolodi losungiramo zinthu zozizira limapangidwa ndi zinthu zakunja ndi zinthu zamkati. Kukhuthala kwa bolodi losungiramo zinthu zozizira kumagawidwa m'mitundu isanu: 75mm, 100 mm, 120 mm, 150 mm, ndi 200 mm.
Zipangizo zakunja zimagawidwa m'mitundu itatu: mbale yachitsulo yamitundu yosiyanasiyana, mbale ya aluminiyamu yojambulidwa, mbale ya Baosteel, ndi mbale yachitsulo chosapanga dzimbiri. Kukhuthala kwa zipangizo zakunja kumagawidwa m'magulu 0.4mm, 0.5mm, ndi zina zotero. Zipangizo zamkati zimapangidwa ndi thovu la polyurethane.
Bolodi losungiramo zinthu zozizira lomwe limagwiritsidwa ntchito kwambiri ndi 100 mm, lomwe limapangidwa ndi mbale yachitsulo yamtundu wa 0.4mm wandiweyani komanso thovu la polyurethane. Bolodi losungiramo zinthu zozizira likakula, limakhala ndi mphamvu yabwino yotetezera kutentha. Bolodi losungiramo zinthu zozizira limatha kusinthidwa malinga ndi zosowa za makasitomala.
Pali mitundu itatu ya zitseko zosungiramo zinthu zozizira: zitseko zotsetsereka, zitseko zotsetsereka, ndi zitseko ziwiri. Kukula ndi makulidwe a chitseko, bolodi, ndi zina zotero zitha kusinthidwa malinga ndi zosowa za makasitomala.
2. Chipangizo choziziritsira mpweya m'chipinda chozizira:
Njira yogwirira ntchito ya makina oziziritsira m'chipinda chozizira imapangidwa ndi compressor—> condenser—> madzi osungira thanki—> fyuluta—> expansion valve—> evaporator.
Pali mitundu yambiri ya ma compressor: Copeland (USA), Bitzer (Germany), Sanyo (Japan), Tecumseh (France), Hitachi (Japan), Daikin (Japan), Panasonic (Japan).
Mofananamo, mitundu ya ma refrigerant omwe amawonjezeredwa ku compressor iliyonse ndi yosiyana, kuphatikiza R12, R22, R134a, R404a, R410a, R600
Pakati pawo, R134a, R404a, R410a, ndi R600 ndi mafiriji abwino kwa chilengedwe. , Kupanikizika komwe kumawonjezeredwa ku mafiriji osiyanasiyana nakonso kumasiyana.
1. Ntchito ya kondensala ndikutulutsa kutentha kwa kompresa.
Ngati choziziritsira mpweya chili chodetsedwa kwambiri, kapena ngati choziziritsira mpweya chayikidwa pamalo opanda kutentha koipa, izi zidzakhudza mwachindunji momwe choziziritsira mpweya chimakhudzira kutentha. Chifukwa chake, nthawi zonse, choziziritsira mpweya chiyenera kutsukidwa kamodzi pa miyezi itatu iliyonse, ndipo choziziritsira mpweya chiyenera kuyikidwa pamalo opumira bwino omwe angathandize kuti kutentha kutayike.
2. Ntchito ya thanki yosungiramo madzi ndikusunga choziziritsira madzi
Makina oziziritsira akamayendetsa, compressor imakanikiza mpweyawo kupita ku condenser kuti ichotse kutentha, ndipo choziziritsira chamadzimadzi ndi choziziritsira cha mpweya zidzayenda pamodzi mu chubu cha mkuwa. Panthawiyi, pamene pali choziziritsira chamadzimadzi chochuluka, chotsalacho chidzasungidwa mu thanki yosungiramo madzi. Ngati choziziritsira chamadzimadzi chomwe chikufunika kuti chiziziziritse chili chochepa, thanki yosungiramo madzimadzi idzachidzazanso yokha.
3. Ntchito ya fyuluta ndikusefa zinyalala
Fyuluta idzasefa zinyalala kapena zinthu zodetsedwa zomwe zimapangidwa ndi compressor ndi copper chubu panthawi yoziziritsa, monga fumbi, chinyezi, ndi zina zotero. Ngati palibe fyuluta, zinyalalazi zidzatseka capillary kapena expansion valve, zomwe zimapangitsa kuti makinawo asathe kuziziritsa. Zinthu zikavuta kwambiri, kupanikizika kochepa kudzakhala kupanikizika koipa, komwe kudzawononga compressor.
4. Valavu yokulitsa
Vavu yowonjezera kutentha nthawi zambiri imayikidwa pakhomo la evaporator, motero imatchedwa valavu yowonjezera. Ili ndi ntchito ziwiri zazikulu:
①. Kusintha. Pambuyo poti firiji yamadzimadzi yotentha kwambiri komanso yopanikizika kwambiri yadutsa m'bowo losinthira la valavu yowonjezera, imakhala firiji yamadzimadzi yotentha pang'ono komanso yopanikizika pang'ono, zomwe zimapangitsa kuti firijiyo ituluke.
②. Yang'anirani kayendedwe ka firiji. Firiji yamadzimadzi yolowa mu evaporator imasanduka madzimadzi kupita ku mpweya ikadutsa mu evaporator, imayamwa kutentha, ndikuchepetsa kutentha komwe kumakhala mufiriji. Valavu yowonjezera imalamulira kayendedwe ka firiji. Ngati madzi akuyenda kwambiri, chotulutsira chimakhala ndi madzi oziziritsa, omwe angalowe mu compressor kuti apangitse madzi kusonkhana. Ngati madzi akuyenda pang'ono, madzi amatuluka pasadakhale, zomwe zimapangitsa kuti compressor isasungidwe bwino.
3. Chotenthetsera madzi
Chotenthetsera ndi chipangizo chosinthira kutentha chomwe chimagwiritsidwa ntchito ngati khoma. Chotenthetsera madzi chotentha pang'ono komanso chotsika mphamvu chimasungunuka ndi kuyamwa kutentha mbali imodzi ya khoma losinthira kutentha la chotenthetsera, motero chimaziziritsa chotenthetsera chomwe chili mbali inayo ya khoma losinthira kutentha. Chotenthetsera chozizira nthawi zambiri chimakhala madzi kapena mpweya.
Chifukwa chake, ma evaporator amatha kugawidwa m'magulu awiri: Ma evaporator omwe amaziziritsa zakumwa ndi ma evaporator omwe amaziziritsa mpweya. Ma evaporator ambiri osungiramo zinthu zozizira amagwiritsa ntchito iyi.
4. Bokosi lamagetsi
Bokosi logawa liyenera kusamala ndi malo oyikamo. Nthawi zambiri, bokosi logawa lidzayikidwa pafupi ndi chitseko chosungiramo zinthu zozizira, kotero chingwe chamagetsi chosungiramo zinthu zozizira nthawi zambiri chimakhala ndi mita 1-2 pafupi ndi chitseko chosungiramo zinthu zozizira.
5. Chitoliro cha mkuwa
Apa tiyenera kudziwa kuti kutalika kwa chitoliro cha mkuwa kuchokera ku malo osungira zinthu ozizira kupita ku evaporator kuyenera kulamulidwa mkati mwa mamita 15. Ngati chitoliro cha mkuwa ndi chachitali kwambiri, chidzakhudza momwe zinthu zimakhalira mufiriji.
