Ubusika obubandayo kakhulu buyeza, woza...
Ebusika, asidingi nje kuphela ukuzivikela emakhazeni nokuzigcina sifudumele, kodwa njengabasebenzi befriji, kufanele futhi “sithande futhi sinakekele” imishini yethu yefriji, ikakhulukazi enyakatho ebandayo. Kumelwe sinake umoya opholile ophakathi nendawo futhi sithathe izinyathelo zokuphepha...Funda kabanzi -
Ukuze wenze ifriji, qala uqonde...
I-refrigerant, eyaziwa nangokuthi i-refrigerant, iyisithako esisebenzayo ohlelweni lokuqandisa. Njengamanje, kunezinhlobo ezingaphezu kuka-80 zezinto ezingasetshenziswa njengeziqandisi. Iziqandisi ezivame kakhulu yi-Freon (kufaka phakathi: R22, R134a, R407c, R410a, R32, njll.), i-ammonia (NH3), amanzi (H2O...Funda kabanzi -
I-compressor ye-piston yesiqandisi ayi ...
I-compressor ingumshini oyinkimbinkimbi osebenza ngesivinini esikhulu. Ukuqinisekisa ukugcotshwa okwanele kwe-crankshaft ye-compressor, ama-bearings, izinduku zokuxhuma, ama-piston nezinye izingxenye ezihambayo kuyimfuneko eyisisekelo yokugcina ukusebenza okuvamile komshini. Ngenxa yalesi sizathu, i-compressor ikhiqiza...Funda kabanzi -
Ipayipi Lomugqa Weyunithi Yesiqandisi Ehambisanayo ...
1. Ukwethulwa kwama-Parallel Refrigeration Units I-Parallel unit ibhekisela kuyunithi yokuqandisa ehlanganisa ama-compressor angaphezu kwamabili ku-rack eyodwa futhi ikhonza ama-evaporator amaningi. Ama-compressor anomfutho ofanayo wokuhwamuka kanye nomfutho wokujiya, futhi iyunithi ehambisanayo ingazishintsha ngokuzenzakalelayo...Funda kabanzi -

1. Kungani isimo sezulu sibanda, umphumela wokushisa uba mubi kakhulu? Impendulo: Isizathu esiyinhloko ukuthi uma isimo sezulu sibanda futhi izinga lokushisa langaphandle liphansi, kuba nzima kakhulu ukuthi umshini womoya umunce ukushisa komoya ovela endaweni yomoya wangaphandle, okuholela ekudakeni...Funda kabanzi -
Ama-screw refrigeration compressors avame...
Ama-screw friji compressors angama-volumetric compressors. Njengoba esetshenziswe kusukela ngo-1934, ngenxa yokusebenza kwawo okuhle kakhulu, ukungagugi, kanye nomthamo omkhulu wokupholisa, abusa izinhlelo zokuqandisa ezincane kuya kwezinkulu neziphakathi. Ngakho-ke yiziphi izinhlobo zokwehluleka ezivame...Funda kabanzi -
Umgomo womjikelezo wemigqa eminingi kanye...
Icindezelwe yi-compressor, igesi yokuqala yesiqandisi enokushisa okuphansi kanye nokucindezela okuphansi icindezelwa ibe umusi oshisayo kakhulu nokushisa okuphezulu, bese ikhishwa epayipini lokukhipha umoya le-compressor. Ngemva kokuba isiqandisi esinokushisa okuphezulu kanye nokucindezela okuphezulu sisusiwe...Funda kabanzi -

isivikelo sesixwayiso Imishini yokuzivikela yomuntu siqu efana namagilavu, izibuko, izicathulo kufanele ihlinzekwe uma usebenzisa le mishini. Izinsizakalo zokufaka, ukuqalisa ukusebenza, ukuhlola, ukuvala kanye nokulungisa kufanele zenziwe ngabasebenzi abafanelekayo (oomakhenikha besiqandisi noma ochwepheshe bakagesi) abanezanele...Funda kabanzi -
