Iyunithi Yesiqandisi Ichazwe
Amayunithi okuqandisa egumbi elibandayo, njengemishini eyinhloko ekuqandisweni kwezimboni zesimanje, isetshenziswa kabanzi ezindaweni zokugcina izinto ezibandayo, ekucubunguleni ukudla, kumakhemikhali, kwezokwelapha, nakweminye imikhakha. Ukuqonda ukwakheka kwazo kanye nezimiso zokusebenza kubalulekile ekukhetheni, ekufakeni, nasekugcineni amayunithi okuqandisa. Lesi sihloko sizochaza izingxenye eziyinhloko kanye nemisebenzi yeyunithi yokuqandisa.
I. Izingxenye Eziyisisekelo Zeyunithi Yokujiya Iyunithi yokuqandisa ikakhulukazi yakhiwe izingxenye ezine eziyinhloko: i-compressor, i-condenser, i-evaporator (ngezinye izikhathi ebizwa nangokuthi ifeni), kanye ne-valve yokunweba. Lezi zenezelwa yizingxenye ezifana ne-oyela separator, i-liquid receiver, ingilazi yokubona uwoyela, kanye nesihlungi sokubuyisela i-valve yohlobo lwe-diaphragm, okwenza uhlelo oluphelele lokuqandisa.
I-compressor yesiqandisi: Njenge "nhliziyo" yesistimu yesiqandisi, i-compressor inesibopho sokucindezela igesi yesiqandisi esinokushisa okuphansi, enomfutho ophansi ibe yigesi yesiqandisi esinokushisa okuphezulu, enomfutho ophakeme, okuhlinzeka ngamandla omjikelezo wesiqandisi.
I-Condenser: Ku-condenser, igesi yesiqandisi eshisa kakhulu, enomfutho ophezulu iyapholiswa bese ihlanganiswa ibe uketshezi olunomfutho ophezulu ngokushabalalisa ukushisa. Ukushisa okukhishwa kule nqubo kuvame ukuthwalwa ngamanzi noma umoya opholile.
Iyunithi yomshini wokufudumeza: I-refrigerant yoketshezi olunomfutho ophezulu iyahwamuka kumshini wokufudumeza ngemva kokucindezelwa yidivayisi yokubhoboza (njenge-valve yokwandisa), imunca ukushisa okuvela endaweni ezungezile ukuze kufezwe umphumela wokupholisa. I-evaporator iyisici esibalulekile kuyunithi yomshini wokufudumeza ukuze kushintshwe ukushisa nomhlaba wangaphandle.
I-Expansion Valve: I-expansion valve ilawula ukugeleza kwe-refrigerant ku-evaporator, iqinisekisa ukuthi i-refrigerant ingashabalalisa ngokuphelele futhi imunce ukushisa.
II. Izinhlobo kanye nezici zamayunithi okuqandisa
Amayunithi esiqandisi angahlukaniswa ngezinhlobo eziningana ngokusekelwe esimweni sawo, uhlobo lwe-compressor, kanye nesimo sesicelo.
Ukuhlukaniswa ngokwesimo kanye nohlobo lwe-Compressor:
Iyunithi Yokupholisha Ukukhipha Ishaja Eceleni: I-compressor kanye ne-condenser zihlanganiswa ndawonye, zivamise ukusetshenziswa ezinhlelweni zokuqandisa ezincane kuya kweziphakathi.
Iyunithi Yokukhipha Okuphezulu: Ifanele izinhlelo ezinkulu zokuqandisa, inikeza ukushabalalisa ukushisa okungcono.
III. Ukukhethwa Nokusetshenziswa Kweziyunithi Zesiqandisi
Uma ukhetha iyunithi yokuqandisa, kunezinto eziningana okumele zicatshangelwe, okuhlanganisa umthamo wokupholisa odingekayo, izinga lokushisa elizungezile, uhlobo lwe-condenser, ukukhetha i-compressor, kanye nokulungiswa okukhethekile okudingekayo ezindaweni zokugcina ezibandayo eziqandisa ngokushesha noma eziphakathi nendawo kuya kwezinkulu. Ukukhetha iyunithi efanele kubalulekile ekuqinisekiseni ukusebenza kwefriji, ukunciphisa ukusetshenziswa kwamandla, kanye nokwandisa isikhathi sokuphila kwemishini.
Ngesikhathi esifanayo, ukufakwa nokugcinwa kwamayunithi okuqandisa kumele kuhambisane nezindinganiso zobungcweti. Isibonelo, ngesikhathi sokufakwa, kubalulekile ukuqinisekisa ukuthi azikho izinto zangaphandle ezingena ku-heat exchanger ukuze kugwenywe ukuvaleka noma ukushintshaniswa kokushisa okubi; ngesikhathi sokusebenza kwesistimu, ishaja yesiqandisi, isimo sokusebenza kwe-compressor, kanye nomphumela wokushabalalisa ukushisa kwe-condenser kumele kuhlolwe njalo ukuqinisekisa ukusebenza kwesistimu okuzinzile.
IV. Imikhuba Yokuthuthukiswa Kwamayunithi Okuqandisa
Ngokuthuthuka okuqhubekayo kobuchwepheshe bokuqandisa, amayunithi okuqandisa athuthuka aye ekusebenzeni kahle okuphezulu, ukonga amandla, kanye nobungane nemvelo. Ucwaningo kanye nokusetshenziswa kwama-refrigerant amasha, ukwethulwa kwezinhlelo zokulawula ezihlakaniphile, kanye nokwamukelwa kobuchwepheshe bokonga amandla obusebenza kahle kakhulu kuzothuthukisa ukusebenza kanye nolwazi lomsebenzisi lwamayunithi okuqandisa.
Ukuhlukaniswa Ngokwesakhiwo Seyunithi:
Iyunithi Ehlanganisiwe Ehlanganisiwe Ngokugcwele: Izingxenye ezine eziyinhloko kanye nemishini yokulawula kagesi zihlanganiswa ndawonye, okwenza kube lula ukufakwa futhi zifanele izindawo zokugcina izinto ezibandayo ezincane.
Iyunithi Engenawo Umswakama Ongaphelele: I-compressor ivalwe kancane, ifanele izinhlelo zokuqandisa eziphakathi nendawo kuya kwezinkulu.
Iyunithi yePiston/Isikulufu Esihambisanayo: Isebenzisa ama-compressor amaningi asebenza ngokuhambisana, okuthuthukisa amandla okupholisa kanye nokuqina kohlelo.
Amayunithi okupholisa apholile ngamanzi: Sebenzisa amanzi njengendlela yokupholisa, enikeza ukusebenza kahle kokusatshalaliswa kokushisa okuphezulu futhi afanele izindawo ezinokushisa okuphezulu kanye nomswakama ophezulu.
Amayunithi okuncibilikisa ashisayo: Aklanyelwe ngokukhethekile izinhlelo zokuqandisa ezidinga ukuncibilikisa ngezikhathi ezithile, njengegumbi lokugcina izinto ezibandayo elinokushisa okuphansi
