Kupanga kosungirako kuzizira kumagawidwa m'magawo asanu: chipinda chosungirako kuzizira, bolodi losungirako kuzizira (kuphatikiza chitseko chosungirako kuzizira), evaporator, bokosi logawa, chitoliro chamkuwa.
Kusungirako kozizira
1. Tiyeni tikambirane kaye za bolodi lozizira:
The ozizira yosungirako bolodi wapangidwa ndi zinthu wosanjikiza kunja ndi zamkati wosanjikiza zakuthupi. The makulidwe a bolodi ozizira yosungirako lagawidwa mitundu isanu: 75mm, 100 mm, 120 mm, 150 mm, ndi 200mm.
Zinthu zakunja zosanjikiza zimagawidwa m'mitundu itatu: mbale yachitsulo yamtundu, mbale ya aluminiyamu yojambulidwa, mbale ya Baosteel, ndi mbale yachitsulo chosapanga dzimbiri. The makulidwe a kunja wosanjikiza zakuthupi anawagawa 0.4mm, 0.5mm, etc. mkati wosanjikiza zakuthupi amapangidwa polyurethane thovu.
Bolodi yosungiramo ozizira yomwe imagwiritsidwa ntchito kwambiri ndi 100 mm, yomwe imakhala ndi mbale yachitsulo yamtundu wa 0.4mm kuphatikiza thovu la polyurethane. Kukhuthala kwa bolodi losungirako kuzizira, kumapangitsanso mphamvu ya kutchinjiriza. Bokosi losungirako kuzizira likhoza kusinthidwa malinga ndi zosowa za makasitomala.
Pali mitundu itatu ya zitseko zozizira zosungirako: zitseko zotsetsereka, zitseko zotsetsereka, ndi zitseko ziwiri. Kukula ndi makulidwe a chitseko, bolodi, etc. akhoza kusinthidwa malinga ndi zofuna za makasitomala.
2. Chipinda chozizira chokondera:
Njira yogwirira ntchito ya firiji ya chipinda chozizira imapangidwa ndi kompresa—> condenser—> thanki yosungiramo madzi—> fyuluta—> valve yowonjezera—> evaporator.
Pali mitundu yambiri ya compressor: Copeland (USA), Bitzer (Germany), Sanyo (Japan), Tecumseh (France), Hitachi (Japan), Daikin (Japan), Panasonic (Japan).
Momwemonso, mitundu yamafiriji omwe amawonjezeredwa ku kompresa iliyonse ndi yosiyana, kuphatikiza R12, R22, R134a, R404a, R410a, R600.
Pakati pawo, R134a, R404a, R410a, ndi R600 ndi mafiriji osunga zachilengedwe. , Kupanikizika komwe kumawonjezeredwa mufiriji zosiyanasiyana kumasiyananso.
1. Ntchito ya condenser ndi kutaya kutentha kwa compressor.
Ngati condenser ndi yonyansa kwambiri, kapena chipinda chosungirako chozizira chimayikidwa pamalo opanda kutentha kwabwino, chidzakhudza mwachindunji zotsatira za firiji zosungirako kuzizira. Choncho, nthawi zonse, condenser imayenera kutsukidwa kamodzi pa miyezi itatu iliyonse, ndipo chipinda chosungiramo kuzizira chiyenera kuikidwa pamalo abwino omwe amachititsa kuti kutentha kuwonongeke.
2. Ntchito ya thanki yosungiramo madzi ndi kusunga refrigerant yamadzimadzi
Pamene firiji ikugwira ntchito, kompresa imapanikiza gasi kupita ku condenser kuti iwononge kutentha, ndipo refrigerant yamadzimadzi ndi mpweya wozizira zimayenderera pamodzi mu chubu chamkuwa. Panthawiyi, pamene pali madzi ambiri mufiriji, owonjezerawo amasungidwa mu thanki yosungiramo madzi. Ngati firiji yamadzimadzi yofunikira kuti mufiriji ikhale yochepa, thanki yosungiramo madzi imangowonjezeranso.
3. Ntchito ya fyuluta ndikusefa zonyansa
Fyulutayo idzasefera zinyalala kapena zonyansa zopangidwa ndi compressor ndi chubu yamkuwa panthawi ya firiji, monga fumbi, chinyezi, ndi zina zotero. Ngati palibe fyuluta, zinyalalazi zidzatsekereza capillary kapena valavu yowonjezera, ndikupangitsa dongosolo kuti lisawonongeke. Zinthu zikavuta kwambiri, kutsika kochepa kudzakhala kupanikizika koyipa, komwe kungayambitse kuwonongeka kwa compressor.
4. Vavu yowonjezera
Valavu yowonjezera ya thermostatic nthawi zambiri imayikidwa pakhomo la evaporator, choncho imatchedwa valve yowonjezera. Lili ndi ntchito ziwiri zazikulu:
①. Kutembenuka. Pambuyo pa kutentha kwambiri komanso kuthamanga kwambiri kwamadzimadzi kupyola mu dzenje la kutembenuka kwa valavu yowonjezera, imakhala yotsika kwambiri komanso yotsika kwambiri ya nkhungu ngati hydraulic refrigerant, kulenga zinthu za evaporation ya refrigerant.
②. Yang'anirani kutuluka kwa firiji. Refrigerant yamadzimadzi yomwe imalowa mu evaporator imasanduka nthunzi kuchokera kumadzi kupita ku gasi ikadutsa mu evaporator, imatenga kutentha, ndipo imachepetsa kutentha m'malo ozizira. Valavu yowonjezera imayendetsa kayendedwe ka firiji. Ngati kutuluka kwake kuli kwakukulu, kotulukako kumakhala ndi refrigerant yamadzimadzi, yomwe imatha kulowa mu kompresa kuti ipangitse madzimadzi. Ngati kutuluka kwake kuli kochepa, mpweya umatsirizidwa pasadakhale, zomwe zingayambitse firiji yosakwanira ya kompresa.
3. Evaporator
Evaporator ndi chipangizo chosinthira kutentha kwa khoma. The otsika kutentha ndi otsika-anzanu madzi refrigerant vaporize ndi kuyamwa kutentha mbali imodzi ya kutentha kutengerapo khoma la evaporator, potero kuziziritsa sing'anga mbali ina ya kutentha kutengerapo khoma. Malo ozizira nthawi zambiri amakhala madzi kapena mpweya.
Choncho, evaporators akhoza kugawidwa m'magulu awiri. Ma evaporator omwe amaziziritsa zamadzimadzi ndi ma evaporator omwe amaziziritsa mpweya. Ambiri ozizira yosungirako evaporators ntchito yotsirizira.
4. Bokosi lamagetsi
Bokosi logawa liyenera kumvetsera malo oyikapo. Nthawi zambiri, bokosi logawa lidzakhazikitsidwa pafupi ndi khomo losungirako kuzizira, choncho chingwe chamagetsi chozizira chimakhala ndi mamita 1-2 pafupi ndi chitseko chosungirako ozizira.
5. Chitoliro chamkuwa
Tiyenera kuzindikira apa kuti kutalika kwa chitoliro chamkuwa kuchokera kumalo osungirako ozizira kupita ku evaporator kuyenera kuyendetsedwa mkati mwa mamita 15. Ngati chitoliro chamkuwa ndi chotalika kwambiri, chidzakhudza zotsatira za firiji.
