Chinese brand VS yekunze mhando, ndeipi yekusarudza?

Kuti tiwedzere kunzwisisa mashandisirwo emhando yepamusoro-inoshanda mota uye inverters, takaita hurukuro nevamwe vashandisi veindasitiri.Munguva yekukurukurirana, vangangosvika zana muzana emabhizinesi vakaratidza kuti vakanyatsoona kukosha kwekuchengetedza simba uye kudzikisira mashandisirwo, uye zvishoma nezvishoma vari kumisa mimwe michina kana zvigadzirwa zvine simba rekugadzira zvechinyakare, kutsiva midziyo yekuchengetedza simba nekuvandudza maitiro.

Mukuita kwekusimudzira michina, vashandisi vazhinji vanotanga vabvunza mubvunzo: ndeupi unonyanya kukodzera mutengo wekutenga mota kana yakakwira simba rekushandisa?

Kubva pamaonero ekudyara kwemutengo wenguva pfupi, mutengo wemamota akakwira-akakwira kupfuura iwo echinyakare mota, uye saizi yesimba uye zvinodiwa zvekushandisa zvechigadzirwa zvinokanganisa mutengo chaiwo.Mukufamba kwenguva,mota dzepamusoro-sorokuva nepamusoro-soro, mararamiro akareba, uye mamwe mabhenefiti pasi pemaitiro akajairwa ekuchengetedza simba uye kuderedza kuburitsa.Inotungamirwa nemitemo uye matekinoroji, hunyanzvi hwepamusoro uyemagetsi ekuchengetedza simbaicharamba ichideredza mari, uye hupfumi huchawedzera kubuda.Vatengi vanowedzera vanoda kuisa mari muzvigadzirwa zvinochengetedza simba senge mota dzakasimba uye inverters.
