Ukuze kusizwe abangebona ochwepheshe baqonde kangcono imiqondo yokonga amandla, ezinye zezincazelo zobuchwepheshe ezingezansi zingase zingabi nzima ngokuphelele. Ochwepheshe bayacelwa ngomusa ukuthi baqonde.
Kungani kubalulekile ukuthi abasebenzi bebhizinisi benze ucwaningo lokuqala?
Lokhu kwenzelwa ukunquma ukuthi ibhizinisi lisebenza kahle yini (inqobo nje uma ukukhiqizwa kuyinto evamile, ukusetshenziswa kwamanzi ngokuvamile kuyinto evamile), nokuthi imishini edinga ukulungiswa kabusha okonga amandla isebenza kahle yini.
Lokhu kuvimbela izimo lapho, lapho kufika endaweni, kutholakala ukuthi umkhiqizo awujwayelekile kanye nokusetshenziswa kwamanzi okungajwayelekile, okwenza idatha yokulinganisa ingathembeki futhi kubangele abasebenzi bethu bokuhlola ukuthi bahambe ngendlela elahlekile.
Kungani idatha enikezwa abasebenzisi noma eqoqwe endaweni ingasetshenziswa njengereferensi kuphela?
Izinsimbi eziningi zokubonisa ezisendaweni—njengezikali zokucindezela, amamitha okugeleza, nama-ammeter—ngokuvamile aziba zinembile ngokuhamba kwesikhathi ngenxa yokuntuleka kokulinganiswa. Emabhizinisini amaningi, lezi zinsimbi azilinganiswa njalo (futhi kwezinye izimo, azilinganiswa nhlobo), ngisho nalapho kwaziwa ukungalungi.
Ukusebenzisa idatha engalungile kanjalo kungaholela emaphutheni ekubaleni amazinga okonga amandla kanye nokonga amandla okuphelele.
Isibonelo, amathuluzi afana nalawo aboniswe esithombeni azoba nokwehluka okungenakugwenywa ngemva kokusetshenziswa isikhathi eside. Ngaphandle kokulinganiswa ngesikhathi, lawa maphutha azokwanda, futhi amanani abonisiwe azosuka kude namanani angempela.
Abanye bangase babuze: “Uma kunjalo, ungaqinisekisa kanjani ukuthi amathuluzi akho anembile?” Impendulo inguyebo—siqinisekisa ukunemba ngokuthumela amathuluzi ethu okuhlola ezinkampanini zokulinganisa zobungcweti minyaka yonke.
Kungani kungcono ukwenza ukuhlolwa kokonga amandla ngesikhathi sezulu esishisayo (ehlobo)?
Ezinhlelweni zokupholisa ezijikelezayo (ezivame kakhulu ezimbonini ezifana nensimbi, amakhemikhali, kanye nezitshalo zikagesi; hhayi kakhulu ezinhlelweni ezifana nokuhlinzekwa kwamanzi kamasipala), ukujikeleza kwamanzi kuyanda njengoba isimo sezulu sishisa kakhulu.
Ngezikhathi ezishisa kakhulu, isidingo samanzi sokukhiqiza sifinyelela esicongweni saso (uma sicabangela izimo zokukhiqiza ezijwayelekile). Lapho isidingo samanzi siphezulu, ukukhishwa kwepompo kwandiswa kakhulu, kanti ukusetshenziswa kwamandla kagesi nakho kuphakeme kakhulu.
Ngakho-ke, lesi yisikhathi esifanele kakhulu sokuhlola.
Yiqiniso, ukuhlola ngezinye izikhathi akuyona into engenakwenzeka. Kodwa-ke, phakathi nokuhlolwa okunjalo, amakhasimende kumele abambisane ngokushintsha ukusetshenziswa kwamanzi ukuze alingise izimo eziphakeme kakhulu. Noma kunjalo, kungase kube nomehluko omncane uma kuqhathaniswa nokusetshenziswa okuphezulu kakhulu. Ngakho-ke, ukwenza ukuhlolwa ngezikhathi zasehlobo ezishisa kakhulu kungcono.
Incazelo emfushane yezinto ezidlulisela ukushisa ezinhlelweni zamanzi okupholisa ezijikelezayo
Ingxenye enkulu yamaphampu esiwafakela kabusha ukuze songe amandla isetshenziswa ezinhlelweni zokupholisa ezijikelezayo. Nakuba izimiso zawo ngokuvamile zifana, sizozichaza ngendlela elula.
Kunezici ezintathu eziyinhloko ezithinta ukudluliselwa kokushisa (noma ukushabalaliswa kokushisa):
umehluko wokushisa, i-coefficient yokudlulisa ukushisa, kanye nendawo yokudlulisa ukushisa.
Ake sichaze ngezibonelo ezilula:
1. Umehluko Wezinga Lokushisa
Ukugqoka imikhono emifushane kuzwakala kuhluke kakhulu ehlobo uma kuqhathaniswa nobusika. Ebusika, uzizwa ubanda kakhulu—yize izinga lokushisa lomzimba wakho lihlala licishe libe ngu-37°C.
Cabanga:
- Izinga lokushisa elizungezile lasehlobo: 30°C
- Izinga lokushisa lasebusika: -10°C
Umehluko wokushisa:
- Ihlobo: 37 − 30 = 7°C
- Ubusika: 37 − (−10) = 47°C
Ngokusobala, umehluko wokushisa mkhulu kakhulu ebusika, okuholela ekulahlekelweni ukushisa okusheshayo emzimbeni—yingakho umuzwa wokubanda. Lokhu kubonisa ukuthi lapho umehluko wokushisa umkhulu, kulapho ukudluliselwa kokushisa kushesha khona.
2. I-Heat Transfer Coefficient
Ebusika, ukuphuma ngaphandle ngemva kokugeza ubuso bakho kuzwakala kubanda kunokungabugezi. Lokhu kungenxa yokuthi isilinganiso sokudlulisa ukushisa siyanda, okuholela ekulahlekelweni ukushisa ngokushesha.
3. Indawo Yokudlulisa Ukushisa
Lokhu kulula ukukuqonda: lapho indawo yokudlulisa ukushisa inkulu, kulapho inani lokushisa lincipha khona.
Imiphumela engokoqobo
Uma indawo ibika ukupholisa okunganele noma ukungakwazi ukunciphisa izinga lokushisa, kunezixazululo ezintathu ezivamile:
- Khulisa izinga lokugeleza kwephampu
(Ukugeleza okuphezulu → isivinini esiphezulu → indawo yokudlulisa ukushisa enkulu ngempumelelo) - Sebenzisa i-heat exchanger ene-heat transfer coefficient ephezulu
- Linda isimo sezulu esibandayo
(Izinga lokushisa eliphansi elizungezile ngokwemvelo lithuthukisa ukudluliselwa kokushisa)
Phakathi kwalokhu, ukwanda kokugeleza kwephampu ngokuvamile kuyisisombululo esiwusizo kakhulu nesisetshenziswa kakhulu.
Kungani abasebenzi bamakhasimende kufanele bahambisane nokuhlolwa kokonga amandla?
Ngenxa yezizathu zokuphepha. Amaphampu, ama-motor, kanye namakhabhinethi okulawula angase anikwe amandla. Ukusebenza okungalungile—njengokuqala noma ukuvala okungahlosiwe—kungathinta ukukhiqizwa noma kubangele izehlakalo zokuphepha.
Ngakho-ke, abasebenzi abangochwepheshe kumele babe khona ngesikhathi sokuhlolwa.
