Jonga kule nombolo, le yimeko yokuqhuba usuku, kuba asiyi kuzaliswa nge-90 ngokwayo i-120 degrees, i-peak idla ngokukhutshwa kwi-99.

Izidanga ezi-6. Kuba abathengi bethu bangabasebenzisi beshishini abaqhelekileyo, umthwalo mkhulu kakhulu emini. Ngokukodwa eShanghai, zonke ii-air conditioners zivulwa emini, kodwa akukho mntu uhleli ngokuhlwa, siyaqonda ukuba amaxabiso ombane aphezulu kwimimandla eyahlukeneyo abandakanya iinxalenye ezimbini, enye yi-8-12 ekuseni, kwaye enye yi-6- Ubusuku be-10, abanye Indawo inokwahluka kancinci, kodwa kunjalo.

Ukuba sibeka kuphela inxalenye ephezulu ngexesha lasekuseni, ayigqitywanga, kuba ngokusisiseko akukho mntu ngokuhlwa, kodwa siya kwenza ngenxa yale mfuneko (ukulinganisa iiyure ezingama-24 ngosuku, ungagqithisi umgangatho) beka umbane omninzi emva kwemini. Iindidi ezahlukeneyo zabathengi kwizicelo ezisebenzayo ziya kuhlangabezana neengxaki ezahlukeneyo. Ke ngoko, kwixabiso eliphezulu lombane elikhankanywe ngasentla, ingeniso eshiyekileyo ye-68.

I-5 yuan ifikelelwe, kwaye ingeniso yonyaka imalunga ne-21,900. Ukongeza, kukho iindleko zeebhili zombane. Kwiimeko eziqhelekileyo, abathengi baye baxabisa i-80KW.

Emva kwexesha, sincoma ukuba abathengi bafake i-60kw, thina ngokwabo ukunceda i-20KW. Kutheni sisenza isicelo senkqubo engama-20kW? Enyanisweni, ngenxa yokuba i-voltage yebhetri iyancipha xa inkqubo yokugcina amandla isebenza, ikhoyo ngoku igxininisekile, ngoko ke amandla aphumayo akhoyo ayancipha ngokusisiseko. Ngenxa ye-inshurensi, amandla emveliso ye-20kW yi-50%, ngokwe-50%, yi-10KW ngenyanga, igcina i-5040 yuan ngonyaka.

Ngokuthe ngqo uqikelele imbuyekezo kutyalo-mali, siqikelelwa ngokweendleko zenkqubo ye-degree-120 yenkqubo, mhlawumbi ukubuyisela iindleko zotyalo-mali kwi-4.45, kwaye ibalwa ngokonyaka omnye wokuqhuba iintsuku ze-320, oku hayi ithiyori, yinyani Bala. Le yingxelo yenkqubo yokugcina imihla ngemihla.

Le ngxelo ingasetyenziselwa inkqubo ye-1MWH, i-1MWH yenziwe kwiinkqubo ezisithoba, ukusuka apha ungabona ukuba imbuyekezo kwi-investment ilungile kakhulu. Ndiqikelela iqhekeza lemali apha, ndinokuba yi-0.8 yuan kulo nyaka uzayo, kwaye ileli inokuba yi-0.

6 yuan ekupheleni konyaka. Eyona nto ibalulekileyo kukusebenzisa ibhetri yomhlalaphantsi yemoto yombane. (Eli nqaku laziswa ngokurekhodwa kwentlanganiso, ngaphandle kokuphononongwa).
