Uma ukhetha umshini wendlu odingekayo kuzo zonke izindlu - isitsha esiqandisini - izici eziningi kufanele zicatshangelwe: umakhi, ubukhulu, umthamo wamagumbi okuqandisa kanye namaqabunga, indawo yabo, uhlobo lweqhwa (ukuvuza kanye noqhwa ), inani leminyango, umbala nomklamo wangaphandle, njll. ipharamitha ebalulekile yiklasi lokusetshenziswa kwamandla esiqandisini. Yilokho esizokukhuluma ngakho kulesi sihloko: sizokutshela ukuthi yikuphi nokuthi yiliphi izinga lokusetshenziswa kwamandla okungcono.
Isigaba samandla: kusho ukuthini?
Ukugxila ekusetshenzisweni kwamandla kagesi endlini, saqala ukukhokha maduzane. Kodwa yonke i-kilowatt yamandla ukusetshenziswa kwemithombo yemvelo engenamkhawulo weplanethi yethu: kungaba igesi, amafutha, amalahle. Vumelanisa, emakhaya kunamadivayisi amaningi axhunyiwe kwinethiwekhi kagesi. Futhi isiqandisini singomunye walawo madivaysi asebenze iwashi, izinyanga, iminyaka, "i-kilowatts" evulekayo emitha njengenoma iyiphi enye idivayisi. Futhi emva kwakho konke, ukukhokhelwa kukagesi njalo ngonyaka kuyanda, okubonakalayo kumarisidi wenyanga. Ngakho-ke, abakhiqizi bemishini yasendlini baye bathatha umsebenzi wokuthuthukisa iziqandisini nokusetshenziswa kwazo kwamandla. I-European classification of energy of frijiers yamukelwa, ngokusho ukuthi ukusetshenziswa kwamandla amadivayisi kuboniswa ngezinhlamvu zesiLatini ezivela ku-A kuya ku-G. Isigaba sokusetshenziswa kwamandla ngokwayo silinganiswa nesikhombisi sokusebenza kwamandla, sibalwa ngokulinganisa nangendlela eqondile yinkimbinkimbi esekelwe emiphakathini ehlukahlukene - ukusetshenziswa kwamandla ngonyaka wendawo esiqandisini ku-kW, ukushisa kwedivayisi ngokwayo, inani lamakhamera, ivolumu yabo, uhlobo lokuqandisa kanye nokusetshenziswa kwamandla ajwayelekile.
Amakilasi okusetshenziswa kwamandla amafriji
Ngokusekelwe kuzo zonke izinkomba, amakilasi ayisikhombisa (A, B, C, D, E, F, G) aqale abonakala ngokusekelwe kwenkomba yabo yokusebenza kahle kwamandla. Ngokuqondene nalokho okushiwo yi-class A yokusetshenziswa kwamandla, kufanele kuqashelwe ukuthi isiqandisini esinesimiso esifanayo kufanele sibe nenani lokusebenza kahle kwamandla angaphezu kwama-55%. Kwakuyiqandisini lokhu okushiwo ukuthi kuze kube yamuva kwacatshangwa ukuthi iyona ephezulu kakhulu. Noma kunjalo, inqubekelaphambili ayimi, kanti ngenxa yokusetshenziswa kobuchwepheshe obusha, izinsimbi ezengeziwe eziyinkimbinkimbi zadalwa. Ngakho-ke, kusukela ngo-2003, isiqondiso esisha sesifinyelele, ngokusho ukuthi amakilasi A asebenzayo A + no-A ++ asebenza kahle kangakanani. Ngaphezu kwalokho, isiqandisini se-A + akufanele sisebenzise ugesi ngaphezu kuka-42%, futhi idivayisi eneklasi ye-A ++ yokusetshenziswa kwamandla akufanele idlule i-30% yamanani we-normative. Ngendlela, isabelo somkhiqizo ophelele wamafriji ama-70% futhi sanda njalo.
Uma sikhuluma ngesigaba B sokusetshenziswa kwamandla esiqandisini, khona-ke amadivaysi okugcina imikhiqizo enobumba obunjalo nawo acatshangwa njengokonga ngokweqile, nakuba, kancane kancane, kuneklasi A. Inkomba yokusebenza kahle kwamandla avela ku-55 kuya kuma-75%. Isiqandisini esineklasi lokusetshenziswa kwamandla C libuye libhekise ezingeni lezomnotho lokusetshenziswa kogesi, kodwa ngenani eliphakeme (75 kuya ku 95%).
Uma ku-esiqandisini uthola ilebula nelebula yeklasi yokusebenzisa amandla D, khumbula ukuthi leyo divayisi enexabiso eliphakathi komnotho (kusuka ku-95% ukuya ku-110%).
Kodwa iziqandisisi ezibhalwe nge-E, F, G zizofunda ekilasini ngezinga eliphezulu futhi eliphakeme kakhulu lamandla (kusuka ku-110% ukuya ku-150%).
Ngendlela, ngenxa yokungazi amandla kwamandla, iziqandisini ezinezigaba zokusebenzisa amandla D, E, F no-G azizange zenziwe eminyakeni embalwa edlule.
Njengoba ubona, uma uthenga isila esiqandisini, kufanele uqaphele isigaba salo sokusebenzisa amandla. Ukumaka kwawo kungabonakala emzimbeni wedivayisi ngendlela yesitika.
