1. Ungawugcina kanjani umshini wokuqandisa endaweni yokugcina izinto ebandayo?
(1) Esigabeni sokuqala sokusebenza kweyunithi yokuqandisa, qaphela ukuthi izinga likawoyela le-compressor liku-1/2 yini ukusuka engilazini yokubona uwoyela; ukuthi ukuhlanzeka kukawoyela wokugcoba kuhle yini. Uma kutholakala ukuthi izinga likawoyela lehla ngaphezu kwesilinganiso noma uwoyela wokugcoba ungcolile kakhulu, kufanele kuxazululwe ngesikhathi ukuze kugwenywe ukugcotshwa okubi.
(2) Kwiyunithi epholiswe umoya: hlanza ubuso be-air-cooler njalo ukuze buhlale busesimweni esihle sokushintshana kokushisa.
(3) Kwiyunithi epholiswe ngamanzi: ukungcoliswa kwamanzi okupholisa kufanele kubhekwe njalo. Uma amanzi okupholisa engcolile kakhulu, kufanele ashintshwe.
(4) Qaphela ukuthi uhlelo lwamanzi okupholisa lweyunithi luyasebenza, luyasebenza, luvuza noma luyavuza. Uma lukhona, kufanele luxazululwe ngesikhathi.
(5) Ukuthi isimo sokusebenza sephampu yamanzi sijwayelekile; ukuthi iswishi yevalvu yesistimu yamanzi okupholisa iyasebenza yini; ukuthi isimo sokusebenza sombhoshongo wokupholisa kanye nefeni sijwayelekile.
(6) Kumshini wokuphehla umoya opholile: kuyadingeka ukuhlola ukuthi isimo sokuncibilikisa sijwayelekile yini; ukuthi umphumela wokuncibilikisa umuhle yini, futhi uma kunenkinga, kufanele ixazululwe ngesikhathi.
(7) Qaphela ukuthi i-compressor isebenza kanjani, hlola ukuthi izinga lokushisa lokukhipha umoya kanye nenani lokucindezela lingaphakathi kwesilinganiso esijwayelekile, bese ubhekana nakho ngesikhathi uma kukhona inkinga.
2. Nquma ukuthi isimo sokusebenza se-condenser sijwayelekile yini
Uma ungazi ukuthi isimo sokusebenza se-condenser sijwayelekile yini, ungahlola ukuthi sisebenza kahle yini ngokuthola umehluko wokushisa phakathi kwe-condenser nendawo yokupholisa. Izinga lokushisa lokuncibilikisa le-condenser epholiswe ngamanzi liphakeme ngo-4~6℃ kunezinga lokushisa lokukhipha amanzi okupholisa, kanti izinga lokushisa lokuncibilikisa le-condenser ehwamukayo lihlobene nezinga lokushisa lomoya, elingaphezu kuka-5~10℃ kunezinga lokushisa lebhalbhu emanzi yangaphandle. Izinga lokushisa lokuncibilikisa le-condenser epholiswe ngomoya liphakeme ngo-8~12℃ kunezinga lokushisa lomoya.
3. Ububanzi bokulawula izinga lokushisa lokumunca i-compressor
Ukushisa okuphezulu kokumunca kwe-compressor ohlelweni lokuqandisa kufanele ngokuvamile kulawulwe ngaphakathi kobubanzi obungu-5 kuya ku-15 °C, futhi izinga lokushisa lokumunca le-compressor ohlelweni lokuqandisa lwe-Freon ngokuvamile kufanele libe ngaphezulu kuka-15 °C kunezinga lokushisa lokumunca, kodwa ngokomthetho, akufanele lidlule ku-15 °C. Ngenxa yokuthi izinga lokushisa lokumunca lesistimu yokuqandisa yezindawo zokugcina ezibandayo ezahlukene lihlukile, inani lokushisa lokumunca nalo lihlukile.
4. Ingozi yokushisa komoya okumunca i-compressor okuphezulu kakhulu noma okuphansi kakhulu
Uma izinga lokushisa lokumunca le-compressor liphezulu kakhulu, ivolumu ethile yokumunca ye-compressor izokwanda, amandla okupholisa azoncipha, futhi izinga lokushisa lokukhipha umoya lizokwanda;
Uma izinga lokushisa lokumunca le-compressor liphansi kakhulu, uketshezi oluningi kakhulu lunganikezwa ohlelweni lokuqandisa, futhi i-refrigerant yoketshezi ngeke ivuthwe ngokuphelele ku-evaporator, okuzobangela ukushaywa okumanzi. Naka ukulungiswa nganoma yisiphi isikhathi.
5. Yini okufanele ngiyenze uma uhlelo lokuqandisa lwendawo yokugcina izinto ezibandayo lungenayo i-fluorine eyanele?
Ngesikhathi sokusebenza kohlelo lokuqandisa lwendawo yokugcina ebandayo, ezimweni eziningi, i-refrigerant iyavuza ngenxa yokuntuleka kokuqina kohlelo noma ngesikhathi semisebenzi yokulungisa (njengokushintsha uwoyela, ukukhishwa komoya, ukushintshwa komshini wokomisa isihlungi, njll.), okuholela ekungabikho kokwanele kwe-refrigerant ohlelweni lokuqandisa. Ngalesi sikhathi, kufanele ingezwe ngesikhathi ukuqinisekisa ukusebenza okuvamile kohlelo lokuqandisa.
Uhlelo lokuqandisa lunezelwa nge-refrigerant, futhi ukulungiswa ngaphambi kokushaja kufana nephuzu eliyinhloko lokushaja uhlelo olusha lokuqandisa, ngaphandle kokuthi kukhona i-refrigerant ohlelweni ngaphambi kokushaja, futhi i-compressor isakwazi ukusebenza.
Uhlelo lokuqandisa lunezelwa nge-refrigerant, evame ukushajwa kusukela ohlangothini oluphansi lwe-compressor.
Indlela yokusebenza yesistimu yokubanda yokugcina ifriji ayinayo i-fluorine eyanele: uma i-compressor imisiwe, beka isilinda esiqandisini phansi, sebenzisa amapayipi amabili e-fluorine uma ugcwalisa i-refrigerant, xhuma i-valve yokulungisa ngokulandelana phakathi kwawo, bese uxhuma uhlangothi olulodwa lwepayipi le-fluoride kusilinda, kanye nolunye uhlangothi kumzila wezinhloso eziningi we-valve yokumunca ye-compressor. Okokuqala vula i-valve yesilinda se-freon, sebenzisa umhwamuko we-refrigerant ukukhipha umoya epayipini le-fluorine, bese uqinisa i-interface phakathi kwepayipi le-fluorine kanye nomzila wezinhloso eziningi we-valve yokumunca ye-compressor.
Vula isiteshi sezinhloso eziningi sevalvu yokumunca i-compressor sibe yisimo sezindlela ezintathu. Uma igeyiji yokucindezela kuvalvu yokulungisa ibonakala izinzile, vala ivalvu yesilinda ye-freon okwesikhashana. Qala i-compressor ukuthi isebenze cishe imizuzu eyi-15, bese ubheka ukuthi ingcindezi yokusebenza ingaphakathi kwebanga elidingekayo. Uma ingcindezi yokusebenza ingenakuhlangatshezwa, ivalvu yesilinda ye-freon ingavulwa futhi, futhi i-refrigerant izoqhubeka nokugcwaliswa ohlelweni lokuqandisa kuze kube yilapho ingcindezi yokusebenza ifinyelelwe. Njengoba le ndlela yokugcwalisa i-refrigerant iwukuthi i-refrigerant ishajwa ngesimo somhwamuko omanzi, kuyadingeka ukuvula ivalvu yesilinda ye-Freon kahle ukuze uvimbele i-compressor ukuthi ingangeni emanzini. Lapho ukushaja kuhlangabezana nezidingo, vala ngokushesha ivalvu yesilinda ye-freon, bese uvumela i-refrigerant esele epayipini lokuxhuma ukuthi imuncwe ohlelweni ngangokunokwenzeka, bese ekugcineni uvala isiteshi sezinhloso eziningi, umise ukusebenza kwe-compressor, bese umsebenzi wokushaja i-refrigerant usuphelile. Le ndlela inesivinini sokushaja esihamba kancane, kodwa iphephile kahle uma isiqandisi ohlelweni lwesiqandisi singanele futhi sidinga ukugcwaliswa kabusha.
6. Yini okufanele ngiyenze uma ngifuna ukuvuselela i-desiccant ye-silica gel?
Izinga lokumuncwa komswakama le-desiccant yejeli ye-silica licishe libe ngu-30%. Liyi-crystal block engenabo ubuthi, engenaphunga futhi engaboli enezimbobo eziqinile, izimbobo ezincane, umbala oyinhloko kanye nokushintsha kombala. Ijeli ye-silica enezimbobo ezinkulu imunca umswakama ngokushesha, kulula ukuyigcwalisa, futhi inesikhathi esifushane sokusetshenziswa: ijeli ye-silica enezimbobo ezincane imunca umswakama kancane futhi inesikhathi eside sokusetshenziswa; ijeli ye-silica eshintsha umbala iluhlaza okwesibhakabhaka uma yomile, futhi kancane kancane ishintsha ibe luhlaza okwesibhakabhaka, onsomi-obomvu, futhi ekugcineni ibe nsundu ngemva kokumuncwa komswakama ibomvu futhi ilahlekelwa ikhono le-hygroscopic.
Ukuvuselelwa kwe-desiccant ye-silica gel kungenziwa ngokubeka i-silica gel isilungele ukomiswa bese ivuselelwa kuhhavini ukuze ifudumale futhi ivuselelwe. Setha izinga lokushisa le-oven libe ngu-120 ~ 200°C, bese usetha isikhathi sokushisa sibe amahora angu-3 ~ 4. Ngemva kokwelashwa kokuvuselelwa, i-desiccant ye-silica gel ingasusa umswakama ongaphakathi bese iyibuyisela esimweni sayo sokuqala. Ngemva kokucwilisa izinhlayiya eziphukile, ingafakwa kusihlungi sokomisa ukuze isetshenziswe ngokuphindaphindiwe.
