Zosungirako zozizira zofananira ndi zida za firiji

Kutengera kutentha:

Kutentha kozizira kwambiri (± 5 ℃): koyenera kusunga zipatso ndi masamba.

Kutentha kwapakatikati (00℃~－-5℃): koyenera chakudya chozizira chitatha kusungunuka.

Kutentha kochepa kosungirako kuzizira - 20 ℃): koyenera kupanga mazira, chakudya cha nkhuku - 10 ℃ zinthu zam'madzi.

Zosakhalitsa 23 ℃: oyenera kukhala pang'ono pamaso posungira ozizira zotsatirazi.

Ndi voliyumu:

Malo ozizira pang'ono:<500m³;

Kusungirako kuzizira kwapakatikati: 500 ~ 1000m³;

Kusungirako kwakukulu kozizira: > 1000m³;

Kapangidwe ndi zida zazikulu zosungirako kuzizira

Panel : yopangidwa kale, yokhala ndi kutalika kokhazikika, m'lifupi ndi makulidwe, omwe amatha kusankhidwa malinga ndi zosowa za unsembe wachipinda chozizira. Mbale zokhala ndi makulidwe a 10 cm nthawi zambiri zimagwiritsidwa ntchito posungirako kutentha kwambiri komanso kwapakatikati, ndipo mbale zokhala ndi makulidwe a 12 cm kapena 15 cm nthawi zambiri zimagwiritsidwa ntchito posungirako kutentha pang'ono komanso kusungirako kuzizira.

Kapangidwe ndi zida zazikulu zosungirako kuzizira

Nthawi zonse, mafiriji ang'onoang'ono amagwiritsa ntchito ma compressor a hermetic mokwanira. Mafiriji apakatikati nthawi zambiri amagwiritsa ntchito ma compressor a semi-hermetic. Mafiriji akulu amagwiritsa ntchito semi-hermetic compressor kapena screw compressor. Posankha, ammonia firiji kompresa akhoza kuganiziridwanso, chifukwa ammonia firiji kompresa ali ndi mphamvu ndipo angagwiritsidwe ntchito zolinga zingapo, koma unsembe ndi kasamalidwe ndi zovuta kwambiri.

Evaporator:
Nthawi zonse, malo osungiramo kutentha kwambiri amagwiritsa ntchito mafani ngati ma evaporators, omwe amadziwika ndi kuthamanga kwachangu kuzizira, koma n'zosavuta kuchititsa kuti chinyontho chiwonongeke mufiriji; Malo osungiramo kutentha kwapakati ndi otsika kwambiri amagwiritsa ntchito mapaipi otulutsa mpweya opangidwa ndi mapaipi opanda zitsulo, omwe amadziwika ndi Kutentha kosalekeza kwabwino, ndipo kumatha kusunga kuzizira pakapita nthawi.

Condenser:
Condenser imakhala ndi kuzirala kwa mpweya, kuziziritsa madzi ndi mpweya ndi madzi kuphatikiza njira zoziziritsira. Kuzizira kwa mpweya kumangokhala ndi zida zazing'ono zosungirako zozizira, pomwe zokometsera zoziziritsa madzi zimatha kugwiritsidwa ntchito mumitundu yonse ya firiji.

Valve yowonjezera:
Valavu yowonjezera kutentha imagawidwa kukhala valavu yowonjezera yowonjezera yamkati ndi valve yowonjezera yowonjezera. Kulowetsedwa kwa evaporator kumamveka pansi pa diaphragm ya valve yowonjezera yowonjezera; evaporation imamveka pansi pa diaphragm ya valavu yowonjezera yowonjezera. kutulutsa kuthamanga.

Accumulator:
sungani Freon kuti muwonetsetse kuti firiji imakhala yodzaza nthawi zonse.

Valve ya Solenoid:
Pewani kuti gawo lothamanga kwambiri lamadzimadzi a refrigerant lisalowe mu evaporator pomwe kompresa yayimitsidwa, pewani kutsika kwapansi kuti kusakwera kwambiri pomwe kompresa ikayambika nthawi ina, ndikuteteza kuti kompresa kugwedezeka kwamadzimadzi. Kuonjezera apo, pamene kutentha kwa kusungirako kuzizira kumafika pamtengo wokhazikika, thermostat idzachita, valve solenoid idzataya mphamvu, ndipo compressor idzayima pamene kupanikizika kochepa kumafika pamtengo wokhazikika. Magetsi akayatsidwa, kompresa imayamba pomwe kutsika kwamphamvu kumakwera mpaka kompaniyo akuyamba kukhazikitsa mtengo.

High ndi low pressure protector:
kuteteza kompresa ku kuthamanga kwambiri ndi kutsika kwapansi.

Thermostat:
Ndizofanana ndi ubongo wa malo ozizira ozizira omwe amawongolera kutsegula ndi kutseka kwa firiji, kutsekemera, ndi mafani a malo ozizira.

Zowumitsira Sefa:
fyuluta zonyansa ndi chinyezi mu dongosolo.

Chitetezo cha mafuta:
Onetsetsani kuti kompresa ili ndi mafuta okwanira opaka.

Olekanitsa mafuta:
Ntchito yake ndikulekanitsa mafuta opaka mafuta mu nthunzi yothamanga kwambiri yomwe imatulutsidwa mufiriji kompresa kuonetsetsa kuti chipangizocho chikugwira ntchito bwino komanso moyenera. Malinga ndi mfundo ya kulekanitsa mafuta mwa kuchepetsa kuthamanga kwa mpweya ndi kusintha kayendedwe ka mpweya, tinthu tating'ono ta mafuta mu nthunzi yothamanga kwambiri timasiyanitsidwa ndi mphamvu yokoka. Nthawi zambiri, kuthamanga kwa mpweya kukakhala pansi pa 1m/s, tinthu tating'ono tamafuta tokhala ndi mainchesi opitilira 0.2mm omwe ali mu nthunzi amatha kupatukana. Pali mitundu inayi ya zolekanitsa mafuta zomwe zimagwiritsidwa ntchito nthawi zambiri: mtundu wochapira, mtundu wa centrifugal, mtundu wolongedza ndi mtundu wa fyuluta.
