Ukuqandisa: inqubo yokusebenza yokusebenzisa umthombo wokushisa okuphansi okhiqizwa yifriji ukuze upholise umkhiqizo kusukela ekushiseni okuvamile bese uwuqandisa.
Ukuqandisa: Inqubo yokusebenza yokuthola umthombo wokushisa okuphansi ngokusebenzisa umphumela wokubanda obangelwa ukushintsha kwesimo somzimba sesiqandisi.
Izinhlobo zemishini yokuqandisa: ukukhiqizwa komthombo obandayo (ukuqandisa), ukuqandisa izinto, ukupholisa.
Izindlela zokuqandisa: uhlobo lwe-piston, uhlobo lwesikulufu, iyunithi ye-centrifugal friji compressor, iyunithi yokufumisa ifriji, iyunithi yokufumisa i-steam jet kanye ne-liquid nitrogen.
Indlela yokuqandisa: epholile emoyeni, efakwe emanzini, futhi efrijini ngepayipi lensimbi, udonga kanye nedivayisi yokupholisa yokudlulisa ukushisa ethintana nezinto.
isicelo:
1. Ukuqandisa, ukuqandisa kanye nokuthuthwa kokudla okuqandisiwe.
2. Ukupholisa, ukugcina ebanda, ukugcina umoya olawulwayo kanye nokuthuthwa kokupholisa kwemikhiqizo yezolimo kanye nokudla.
3. Ukucubungula ukudla, njengokomisa okuqandisiwe, ukuhlushwa kokuqandisiwe kanye nokupholisa izinto, njll.
4. Ukupholisa umoya ezindaweni zokucubungula ukudla.
Isimiso Somjikelezo Wokuqandisa
Amadivayisi ayinhloko: i-compressor yesiqandisi, i-condenser, i-expansion valve, i-evaporator.
Umgomo womjikelezo wefriji: Lapho ifriji imunca ukushisa esimweni soketshezi oluphansi nolunomfutho ophansi, iyahwamuka ibe umusi ophansi nonomfutho ophansi, bese ifriji ihwamuka ibe yigesi iba yigesi ephansi nonomfutho ophakeme ngaphansi kwesenzo se-compressor, bese ukuminyana kokushisa okuphezulu nokucindezela okuphezulu kuba uketshezi oluphezulu, uketshezi oluphezulu. Iba uketshezi oluphansi nomfutho ophansi nge-valve yokwandisa, bese imunca ukushisa bese ihwamuka futhi ukuze yakhe umjikelezo wefriji.
Imiqondo Nezimiso Eziyisisekelo
Umthamo wesiqandisi: Ngaphansi kwezimo ezithile zokusebenza (okungukuthi, izinga lokushisa elithile lokuhwamuka kwesiqandisi, izinga lokushisa lokufinyela, kanye nezinga lokushisa lokupholisa), ukushisa okukhishwa yisiqandisi entweni eqandisiwe ngeyunithi ngayinye. Kwaziwa nangokuthi umthamo wokupholisa wesiqandisi. Ngaphansi kwezimo ezifanayo, umthamo wesiqandisi sesisiqandisi esifanayo uhlobene nosayizi, isivinini kanye nokusebenza kahle kwe-compressor.
Ukuqandisa okuqondile: Emjikelezweni wokuqandisa, uma i-evaporator lapho isiqandisi simunca khona ukushisa ishintshanisa ukushisa ngqo nento ezopholiswa noma indawo ezungezile yento ezopholiswa. Ngokuvamile isetshenziswa emshinini wokuqandisa owodwa odinga ukupholiswa kwezimboni, njengefriji ye-ayisikhilimu, indawo yokugcina izinto ebandayo encane kanye nesiqandisi sasekhaya.
Isiqandisi: Into esebenzayo ejikeleza njalo kudivayisi yesiqandisi ukuze kufezwe isiqandisi. Idivayisi yesiqandisi sokucindezela umphunga idlulisa ukushisa ngokushintsha kwesimo sesiqandisi. Isiqandisi siyinto ebalulekile ukuze kufezwe isiqandisi sokwenziwa.
Ukuqandisa okungaqondile: Sebenzisa izinto ezishibhile njengezithwali zemidiya ukuze wenze ukushintshana kokushisa phakathi kwamadivayisi okuqandisa nezindawo noma imishini edla amakhaza.
Isiqandisi: Dlulisa umkhuhlane okhiqizwe ku-evaporator yesiqandisi sedivayisi yesiqandisi uye ekushiseni okumuncwa yinto ezopholiswa, bese uwudlulisela esiqandisini ngemva kokufinyelela kudivayisi yesiqandisi, bese uziphinda uzisebenzise ukuze uphole.
Isimiso Sokuqandisa Okungaqondile Okuhwamukayo
Umgomo wokuqandisa ngokungaqondile: Ngemva kokuba amanzi acwebezelayo amunca amandla okupholisa avela esiqandisini esiku-evaporator, angena endaweni yokugcina ebandayo ngephampu ye-brine, ashintshane ngokushisa nento ezopholiswa noma indawo yokusebenza ukuze amunce ukushisa, bese ebuyela ku-evaporator ukuze aguqule okumuncwe. Ukushisa bese kudluliselwa esiqandisini, esiphinde sisebenzise ukuze siphole.
