Izici zokuthonya kwengcindezi yohlelo lwefriji

1. Izici zengcindezi yokudonsa ephansi:

Ingcindezi yokudonsa ingaphansi kwenani elijwayelekile. Izici zifaka umthamo wokupholisa onganele, umthwalo omncane wokupholisa, ukuvulwa kwevalvethi encane, ingcindezi ephansi yokuncipha (kubhekiswa ohlelweni lwe-capillary), futhi isihlungi asibushelelezi.

Izici zokucindezela okuphezulu:

Ingcindezi yokudonsa iphakeme kunenani elijwayelekile. Izici zibandakanya ifriji eyeqile, umthwalo omkhulu wefriji, ukuvulwa kwevalveji enkulu, ukucindezela okuphezulu (i-capillary tube system), nokusebenza kahle kwe-compressor.

Ingcindezi yokukhipha, izici zokucindezela okuphezulu:

Lapho ingcindezi yokukhipha iphakeme kunenani elijwayelekile, ngokuvamile kunokugeleza okuncane kwendawo yokupholisa noma ukushisa okuphezulu kwendawo yokupholisa, ukukhokhiswa okukhulu kwesiqandisi, umthwalo omkhulu wokupholisa nokuvulwa kwevalveji enkulu.

Lokhu kudale ukuthi ukujikeleza kokujikeleza kwesistimu kukhuphuke, futhi umthwalo wokushisa okwehlisayo nawo ukhuphuke ngokufanayo. Njengoba ukushisa kungasakazeki ngesikhathi, izinga lokushisa lokuncipha lizokhuphuka, futhi konke okungatholwa ukukhuphuka kwengcindezi ye-exhaust (condensing). Lapho izinga lokugeleza kwendawo yokupholisa liphansi noma izinga lokushisa lendawo yokupholisa liphezulu, ukusebenza kahle kokushiswa kwesifudumezi kuyancipha futhi izinga lokushisa lokunciphisa liyakhuphuka.

Lapho izinga lokugeleza eliphakathi nendawo liphansi noma izinga lokushisa eliphakathi nendawo liphakeme, ukusebenza kahle kokushiswa kwesifudumezi kuyancipha futhi izinga lokushisa lokunciphisa liyakhuphuka. Isizathu sokukhokhiswa ngokweqile kwesiqandisisi ukuthi uketshezi lwefriji olwedlulele luthatha ingxenye yeshubhu le-condenser, elehlisa indawo ejiyayo futhi libangele izinga lokushisa lokujija likhuphuke.

Izici zengcindezi yokukhipha okuphansi:

Ingcindezi yokukhipha ingaphansi kwenani elijwayelekile ngenxa yezici ezinjengokusebenza kahle kwe-compressor ephansi, ubuningi beziqandisi obunganele, umthwalo opholile wokupholisa, ukuvulwa kwevalveji encane, nokwehluleka kwesihlungi, kufaka phakathi isikrini sokuhlunga i-valve kanye neqondo eliphansi lokushisa eliphakathi nendawo.

Izici ezingenhla zizodala ukuthi izinga lokugeleza kokupholisa kohlelo lehle, umthwalo we-condensation mncane, futhi izinga lokushisa kwe-condensation lehlisiwe.

Kusukela kuzinguquko ezishiwo ngenhla ekucindezelweni kokumunca nokucindezela kokukhipha, kukhona ubudlelwane obuseduze phakathi kwalokhu okubili. Ngaphansi kwezimo ezijwayelekile, lapho ingcindezi yokudonsa inyuka, ingcindezi yokukhipha inyuka ngokufanele; lapho ingcindezi yokudonsa incipha, ingcindezi yokukhipha iyancipha ngokufanele. Isimo esijwayelekile sokucindezelwa kokukhishwa nakho kungalinganiselwa kusuka ekushintsheni kwegeji yengcindezi yokudonsa.
