Sisebenza Kanjani Isitofu Sikagesi Futhi Ziyini Izinzuzo Zaso?
Izitofu zikagesi zisetshenziswa kakhulu emakhaya esimanje, emafulethini, ngisho nasekhishini lamabhizinisi amancane. Lokhu akubangelwa nje ukubukeka kwazo okuncane nokuhle, kodwa futhi nokusebenza kwazo okusebenzayo kanye nokuphepha okubonakalayo uma kuqhathaniswa nezitofu zikagesi ngaphansi kwezimo ezithile. Kodwa-ke, abantu abaningi basabuza: izitofu zikagesi zikhiqiza kanjani ukushisa, zihluke kanjani ezitofu zikagesi, futhi yiziphi izinzuzo ezibonakalayo ezingatholakala ekusetshenzisweni kwansuku zonke?
Lesi sihloko sixoxa ngendlela izitofu zikagesi ezisebenza ngayo kusukela ezimisweni zazo eziyisisekelo kuya kobuchwepheshe bazo obuhlukahlukene, bese siphetha ngezinzuzo nezinto okufanele uzicabangele ngaphambi kokuthenga.
Iyini Isitofu Sikagesi?
Isitofu sikagesi siwumshini wokupheka oguqula amandla kagesi abe ukushisa abe amabhodwe noma amapani okushisa. Ngokungafani nezitofu zikagesi, ezikhiqiza ukushisa ngokushisa (ilangabi), izitofu zikagesi zikhiqiza ukushisa ngezinto zokushisa noma amasimu kagesi, kuye ngohlobo. Ngenxa yokuthi azisebenzisi ilangabi elivulekile, izitofu zikagesi zivame ukubhekwa “njengezihlanzekile” maqondana nokushisa, yize kusenemiphumela yokusetshenziswa kwamandla okudingeka iqondwe.
Isimiso Esiyisisekelo: Ukuguqula Ugesi Ube Ukushisa
Ngokuyisisekelo, izitofu zikagesi zisebenza ngokusebenzisa enye yalezi zindlela ezimbili ezilandelayo:
1. Ukushisa okumelanayo: ugesi ugeleza ngesakhi sokushisa esinokumelana. Lokhu kumelana kuguqula amandla kagesi abe ukushisa. Isimiso sifana nendlela esebenza ngayo i-heater kagesi noma i-heater yamanzi.
2. Ukufakwa kwe-electromagnetic: ugesi ugeleza nge-coil ukuze ukhiqize insimu yamagnetic eshintshayo. Le nsimu ibangela imisinga kagesi (imisinga ye-eddy) phansi kwamapani athile (enziwe ngezinto ze-ferromagnetic), futhi ukushisa kukhiqizwa ngqo epanini—hhayi esitovini.
Lezi zimiso ezimbili zakha izinhlobo zezitofu zikagesi ezivamile emakethe.
Izinhlobo Zezitofu Zikagesi Nendlela Ezisebenza Ngayo
1) Isitofu Sikagesi Esijikelezayo (Ikhoyili)
Lena imodeli yakudala evame ukutholakala ezitofini zikagesi ezindala noma kumamodeli angabizi.
Izindlela zokusebenza:
– Uma ivuliwe, ugesi ugeleza uye ku-heating element emise okwe-spiral (ngokuvamile insimbi enamandla okumelana nayo njenge-nickel-chromium alloy).
– Isici siyashisa ngenxa yokumelana, bese sidlulisela ukushisa epanini ngokuxhumana ngqo kanye nemisebe yokushisa.
Izici eziyinhloko:
– Ukushisa kuvame ukuba kancane kunokungenisa.
– Ubuso/into iba shushu kakhulu ngakho-ke kudingeka kuqashelwe ngemva kokucima.
2) Isitofu Sikagesi Esikhazimulayo/Esine-Radiant (Isitofu Sokupheka Esine-infrared/Esine-Radiant)
Lesi sitofu sinendawo eyisicaba yengilazi efana ne-ceramic okulula ukuyihlanza.
Izindlela zokusebenza:
– Ngaphansi kwengilazi-ceramic kukhona isici sokushisa sikagesi.
– Lesi sakhi sikhipha ukushisa (imisebe) futhi siqhube ukushisa ngokusebenzisa ubuso kuya epanini.
– Ukushisa kwenzeka ezintweni zesitofu kanye nasezindaweni eziphezu kwazo kuqala, bese kudlulela ezitsheni zokupheka.
Izici eziyinhloko:
– Ukubukeka kwesimanje kanye nendawo eyisicaba.
– Ukushisa okusele kuhlala phezu kobuso ngemva kokupheka.
3) Isitofu Sokungenisa
Lolu uhlobo lwesitofu sikagesi esithandwa kakhulu ngenxa yokusebenza kahle kakhulu kanye nokusabela kwaso ekushiseni okusheshayo.
Izindlela zokusebenza:
– Uma isitofu sivuliwe, i-AC (alternating current) igeleza ku-coil yethusi ngaphansi kobuso bengilazi.
– Ikhoyili idala insimu kazibuthe eshintshayo.
– Uma ipani elihambisanayo libekwa phezulu, insimu yamagnetic ibangela ukugeleza kwamanzi phansi kwepani.
– Amaza e-eddy akhiqiza ukushisa okuqondile epanini (umphumela we-Joule), ngakho ukudla kushisa ngokushesha.
– Ubuso besitofu buhlala bupholile kunesitofu esikhanyayo, ngoba umthombo oyinhloko wokushisa usepanini.
Izici eziyinhloko:
– Kudinga imbiza/ipani elinophansi olune-magnetic (isb. insimbi, insimbi yekhabhoni, insimbi ethile engagqwali).
– Izilungiselelo zokushisa ziyasabela kakhulu.
Kungani Izitofu Zikagesi Zingakwazi Ukulawula Ukushisa Ngokunemba?
Izitofu zikagesi ngokuvamile zihlonyiswe ngezilawuli zikagesi, njenge-thermostat, izinzwa zokushisa, noma amamojula e-inverter (on induction). Kumamodeli alula, amandla alawulwa ngokuvula nokuvala izakhi ngezikhathi ezithile (ukujikeleza komsebenzi). Kuzitofu zokungenisa ezithuthukisiwe kakhulu, ama-inverter angalawula amandla kahle, aqinisekise ukuthi ukushisa kukhishwa njalo, okufanelekela imisebenzi yokupheka ebucayi njengokuncibilikisa ushokoledi noma ukugcina isobho lifudumele.
Ngaphezu kwalokho, ezinye izitofu zesimanje zine:
- Isikhathi sokuvala okuzenzakalelayo,
– ukukhiya (ukukhiya kwengane),
– ukutholwa kwe-pan (ukungeniswa kuphela),
– ukuvikela ukushisa ngokweqile.
Lezi zici zinegalelo ekuphepheni nasekududuzeni.
Izinzuzo Zezitofu Zikagesi
1) Kuphephile engcupheni yokuvuza kwegesi
Ngenxa yokuthi azisebenzisi i-LPG noma igesi yegridi, izitofu zikagesi ziqeda ingozi yokuvuza kwegesi kanye nokuqhuma okungenzeka ngenxa yokwakheka kwegesi. Lokhu kuyinzuzo emafulethini amancane noma emakhaya anomoya omncane. Kodwa-ke, ukuphepha kukagesi kusabalulekile: sebenzisa izindawo zikagesi ezisezingeni eliphezulu, gwema amapulagi ahambisanayo, futhi uqinisekise ukuthi ugesi wasekhaya unamandla anele.
2) Ikhishi Elihlanzekile kanye Nokukhishwa Okuncane Kokushisa
Izitofu zegesi zikhiqiza imikhiqizo yokushisa efana ne-CO₂, umhwamuko wamanzi, futhi ngaphansi kwezimo ezithile, i-CO₂ (i-carbon monoxide) kanye ne-NOx (i-nitrogen oxides). Izitofu zikagesi azinawo ukukhishwa kokushisa ekhishini ngoba azibandakanyi inqubo yokushisa. Lokhu kungasiza ekugcineni ikhwalithi yomoya wangaphakathi, ikakhulukazi lapho ukupheka kuvame ukwenzeka.
3) Ukusebenza Kahle Kokushisa (Ikakhulukazi Ukungenisa)
Izitofu zokungenisa umoya zaziwa ngokusebenza kahle kwazo okuphezulu ngoba ukushisa kukhiqizwa ngqo epanini. Ezitofini zegesi, okunye ukushisa kulahleka emoyeni ozungezile. Umthelela:
– amanzi abilayo ngokushesha,
– ikhishi lizizwa lipholile,
– amandla asetshenziswa kahle kakhulu ekuphekeni.
Kodwa-ke, ukusebenza kahle okuphelele kusathonywa amazinga kagesi, imikhuba yokupheka, kanye nekhwalithi yezitsha zokupheka.
4) Ukulawula Izinga Lokushisa Elizinzile Neliphendula Kakhulu
Esitofini sokupheka esingeniswayo, izinguquko zokushisa zingazwakala ngokushesha, zisondela ekuphenduleni kwesitofu segesi kodwa ngokulawula okunembile. Lokhu kuyasiza uma:
- ukuthosa okusheshayo,
- setha ekushiseni okuphansi,
– amasoso okupheka adinga ukushisa okuzinzile.
5) Kulula Ukuyihlanza
Ubuso obubushelelezi bengilazi ne-ceramic benza kube lula ukusula okuchithekile. Ngenxa yokuthi ukukhishwa akushisi njengokukhanya, izinsalela zokudla azivamile "ukusha" ebusweni ngokushesha, okwenza ukuhlanza kube lula. Yiqiniso, kusadingeka ukuhlanza ngemva kokuba kupholile ukuze kugwenywe imicu.
6) Umklamo Omncane Nobuhle
Izitofu zikagesi eziphathekayo zilungele indawo elinganiselwe, izindawo zokulala, noma amakhishi engeziwe. Amamodeli akhelwe ngaphakathi nawo anikeza ukubukeka okuhle nokunesimanje kwekhawuntara.
Izinto Okufanele Uzicabangele Ngaphambi Kokukhetha
Naphezu kwezinzuzo zazo eziningi, izitofu zikagesi azinazo izinzuzo zazo. Nazi ezinye izinto okufanele uzicabangele:
1. Izidingo zamandla asekhaya: Izitofu zikagesi zingadinga amandla amaningi (isb., ama-watts angu-800–2000 ezitofu eziphathwayo, kanye nangaphezulu ezitofu ezishiswayo eziningi ezakhelwe ngaphakathi). Qinisekisa ukuthi i-MCB kanye nokufakwa kukagesi kwanele.
2. Izindleko zokusebenza: kuncike emazingeni kagesi kanye nesikhathi sokusetshenziswa. Kwezinye izimo, igesi ingaba eyonga kakhulu; kwezinye, ukwenziwa kwayo kube ngcono ngenxa yokusebenza kwayo kahle kakhulu.
3. Ukuhambisana kwezitsha zokupheka (ukufakwa kuphela): ipani kumele libe namandla kanobuthi. Ngaphandle kwalokho, isitofu ngeke sishise kahle.
4. Imikhuba Yokupheka: Uma uvame ukupheka usebenzisa ukushisa okuphezulu, i-wok yendabuko, noma udinga umuzwa "womlilo," abanye abantu basathanda igesi. Kodwa-ke, ekubiliseni, ekuthoseni, ekushiseni, nasekuphekeni kwansuku zonke, isitofu sikagesi sanele ngokuphelele.
5. Ukuphepha kukagesi: sebenzisa izintambo namasokhethi ngokwezindinganiso, gwema ukunwetshwa okushibhile, futhi ungabeki isitofu eduze kwemithombo yamanzi ngaphandle kokuvikelwa.
Isiphetho
Izitofu zikagesi zisebenza ngokuguqula amandla kagesi abe ukushisa—kungaba ngesici sokushisa (i-coil/radiant) noma ngokufakwa kwe-electromagnetic. Kulezi zintathu, izitofu zokufakwa kwe-induction zisebenza kahle kakhulu ngesivinini sokushisa, ukusebenza kahle, kanye nokulawula ukushisa ngoba zifudumeza ipani ngqo. Ngokuvamile, izitofu zikagesi zinikeza ikhishi elicocekile, kulula ukuzihlanza, zisusa ingozi yokuvuza kwegesi, futhi zilungele ukusetshenziswa kwesimanje.
Uma ucabanga ukushintsha, qala ngokunquma izidingo zikagesi zendlu yakho, isitayela sokupheka, kanye nezinhlobo zezitsha zokupheka onazo. Ngokukhetha okulungile, isitofu sikagesi singaba utshalomali olubalulekile olwenza ukupheka kuphephe, kube lula, futhi kusebenze kahle.
Uma uthanda, ngingakusiza ukuncoma uhlobo olufanele kakhulu lwesitofu sikagesi olusekelwe kumandla kagesi endlu yakho (isb. 1300 VA/2200 VA/3500 VA), inani lamalungu omndeni, kanye nemikhuba yakho yokupheka.
