Izinhlobonhlobo ezinkulu zeziqandisini zanamuhla azikwenzi ukukhetha umthengi, okuyivumela ukuba akhethe umhlangano ofanelwe imingcele ehlukahlukene, ewusizo kuye. Ukutholakala kanye nevolumu yendawo yamafriji kanye nendawo yokupholisa, umsebenzi weNoFrost, izinga lomsindo, ukusebenza kahle kwamandla kagesi - zonke lezi zinkomba zikhokhwa cishe wonke umuntu ofuna ukuthenga i-unit unit efriji. Phakathi naleso sikhathi, abathengi bavame ukuphakamisa lo mbuzo: yiyiphi imodeli yokukhetha - nge-compressors eyodwa, amabili noma emithathu? Uyini umehluko?
I-single-compressor unit
Lo mmele wensiza yasendlini uhlinzeka ngesifunda esisodwa sokupholisa, isimo sokushisa senziwa ngesikhathi esisodwa kokubili ekamelweni lokupholisa kanye nefriji.
I-unit-compressor unit ngokuvamile ayikuvumeli ukuthi ucime amakhamera ngabanye. Uma kudingekile ukuhlanza noma ukuhamba isikhathi eside, i-unit kumele isuswe ngokuphelele. Lokhu kuyaphumelela ngokwezomnotho, kodwa ngokuvamile kuvame ukungabi nengozi, ngoba ihrifri ingakwazi ukugcina ezinye izinto zokudla.
Noma kunjalo, kunemithetho yalokhu, ngakho-ke kukhona okuhlukile. Kwezinye izigesi eziqandisini ezine-compressor eyodwa, kune-valenoid valve elawula ukusakazwa kwe-frijiji. Umsebenzi walo wukuthi i-refrigerant ivinjelwe ku-evaporator yegumbi lokushisa, okuholela ekuqedeni ukupholisa kwayo. Ngesikhathi esifanayo, umsebenzi wehrivisi uyaqhubeka. Kubalulekile ukwazi, kungakhathaliseki ukuthi yiyiphi inguqulo yefriji eyodwa-compressor, kunoma yiliphi iyunithi yalolu hlobo ihrifri ayikwazi ukucishwa esiqandisini.
I-compressor emibili (noma ngaphezulu)
Ukwandisa unyaka nonyaka, ukuthandwa okukhulu kwezingxenye ezimbili ze-friji-compressor kungenxa yezizathu eziningi. Iningi (kodwa hhayi konke okubalulekile!) Izingxenye ezimbili ze-friji-compressor zivumela ukuthi ufake ngokuzenzakalelayo futhi ulungise izindlela zokushisa, futhi ukhiphe eceleni ikhamera ngayinye ngokwehlukana. Ngenxa yobukhona besici esinjalo, ungasula ikhamera ngezikhathi ezihlukene, uma kunesidingo. Uma abanikazi bengasisebenzisi isikhathi esiyisiqandisini, ikhamera engeyona yokusebenza inganqanyulwa ekunikezeni amandla, okuzogcina amandla.
Ukumiswa kokushisa okuhlukile kungumsebenzi ovumela ukubeka imingcele enhle yokuqandisa noma yokupholisa.
Ngaphezu kwalokho, izingxenye ezimbili ze-compressor zihlale zihlonyelwe umsebenzi we-super-freezing. Ukusebenza kwalo kuholela ekudoneni kwezinga eliphansi lokushisa ehrijini. Ezinhlobonhlobo zamanye imikhiqizo, izinga lokushisa, lokunciphisa, lifinyelela ngisho nakwe-degrees angu-40.! Ukulula kokushisa okujulile kuhlanganisa ukulondoloza imikhiqizo yezakhi zayo eziwusizo namavithamini amaningi, kanye nokungabhubhisi isakhiwo sezintambo, okuvumela ukuthi umkhiqizo ube musha ngemva kokuphazamiseka.
Kanye nokushisa okujulile, amafriji amabili noma amathathu-compressor anesimo esihlukile sokushisa angahlonyiswa ngemisebenzi yokupholisa okukhulu ekamelweni lokupholisa, izilungiselelo zokushisa ezindaweni ezihlanzekile, "Party", okuvumela isikhathi esifushane ukuphuza iziphuzo efrijini.
Amayunithi amabili-compressor ayenawo njengomsindo njengoba unit eyodwa-compressor. Isizathu salokhu sisezintweni ze-compressors ezisetshenzisiwe kanye nemodi yokusebenza. Ukusetshenziswa kwamagumbi amabili-compressor kuhilela ukusebenza okunye kwe-compressors futhi, ngenxa yalokho, ukukhiqizwa komsindo omncane.
Uma i-unit-compressor unit efrijini isetshenziswa ngokufanele (okuyinto ikakhulukazi enqunywe yendawo yedivaysi, ukukhethwa kwesigaba sayo sezulu, indawo yemikhiqizo, imvamisa kanye nobude bokuvulwa komnyango), khona-ke kusebenza kakhulu futhi kunokwedlula ukwedlula i-single-compressor analogs.
Uma kwenzeka ukuthi elinye lamakomidi lizohlile, iyunithi eyodwa kuphela ye-compressor izosebenza. I-compressor izodinga ukupholisa ivolumu encane, ngakho-ke, umsebenzi usebenza kahle. Lokhu angeke kube yunithi ngesithuthuthu esisodwa: ukuze kufezwe umbuso wokushisa onikeziwe kwelinye lamakamelo, i-compressor izobapholisa kabili ngesikhathi esisodwa.
Yiqiniso, lapho ukhetha i-unit for economy, udinga ukwazi ukuthi inani le-compressors kulesi simiso akuyona into ebalulekile, okufanele ihlawulwe, kusukela kulolu phuzu isigaba sokusebenza kahle kwamandla kubaluleke kakhulu. Manje imakethe inezinhlanganisela, ekilasini layo elidlula ngisho no-A +++!
"Pitfalls", noma ukungalungi kwangempela futhi kungenzeka.
Kuyaziwa, akukho lutho olungcono ... Isithombe semisebenzi emihle kakhulu kanye nezimfanelo zomsebenzi wezinyunithi ezimbili zokuphefumula eziphefumulayo zichitha imali ephezulu yalezi zixhobo. Lezi ziqandisini zizokhokha imali engama-20-30% ngaphezu kokufana ne-compressor eyodwa, ngakho-ke ukuhlanganiswa kwama-compressors amabili kuzokwenyuka kangakanani, kunconywa ukuthi ubale kahle ngaphambi kokuthenga.
Ngenkathi ingxoxo yezindlu eziqandisini zemizi ehlala njalo isinciphisa umbono wokuthi nge-compressors yezinhlobo ezimbili ze-compressor kukhona ukuwohloka okuphindaphindiwe, futhi ngokujwayelekile, le nqubo ishaya kakhulu, ngoba iqukethe imininingwane eyengeziwe nokuklanywa okuyinkimbinkimbi. Yiqiniso, iyunithi eyinkimbinkimbi kakhulu inengozi enkulu yokuphazamiseka okungase kube khona. Noma kunjalo, imikhiqizo idinga ukugcinwa endaweni ethile - hhayi esikhwameni sezintambo ngaphandle kwefasitela noma emiphongolweni. Futhi ohlangothini lwezobuchwepheshe lwendaba luhambisana nezingozi ezincane!
Ukuncintisana okunamandla kwenza abakhiqizi bezingxenye zokuqhaqhazela ukulawula ngokuqinile ikhwalithi yemikhiqizo eyenziwe. "Ukuhamba nge-intanethi" impendulo engathengi yabathengi ingaqeda idumela, ngakho-ke, ukunciphisa ukuthengisa. Ngelinye igama, ikhwalithi yemikhiqizo yezobuchwepheshe iyinkinga ephezulu phambili.
Manje, uma ujwayele izici ze-single-compressor nama-friji-compressor amabili, uqondisa kahle ekusebenzeni okulindelekile okusebenzayo kwemishini oyithandayo futhi, okwamanje, awuholeli kumathengisi abangathembeki okushiwo yizici ezithile noma ezinye zeyunithi, akunakwenzeka ngenxa yezici zokuklama kwayo.
