Makhalidwe achilengedwe a malo okonzera (kuphatikiza makina opangira nthunzi) a shopu yagalimoto 4S ndi awa:
Dera la msonkhanowu nthawi zambiri limakhala pakati pa mazana ndi 2,000 masikweya mita, ndipo kutalika kwa danga kumakhala pafupifupi 10 metres.Chifukwa magalimoto ndi antchito nthawi zambiri amalowa ndi kutuluka, nthawi zambiri zitseko ndi mawindo amakhala otseguka.Kuonjezera apo, zotsatira za nyengo yotentha kwambiri panja, kotero kuti malo ogwirira ntchito m'nyumba ayenera kugwiritsa ntchito utsi wamakina ndikuziziritsa.Pakadali pano, malo ambiri ogulitsa magalimoto apanyumba a 4S amayikidwa m'mafani azikhalidwe zamakhoma kapena mafani oyimilira owumitsa tsitsi.M'nyengo yotentha, kumakhala mpweya wotentha kwa mpweya wochepa.Malo achilengedwe amatsimikiziranso kuti ma air conditioners achikhalidwe (ayenera kugwiritsidwa ntchito pamalo otsekedwa) sangathe kugwiritsidwa ntchito nthawi zonse ndi firiji, kotero palibe njira zabwino zothetsera.

Poyesa kufufuza njira zochepetsera mpweya wa carbon ndi kuzirala m'zaka zaposachedwa, Guangdong XIKOO yachita bwino njira zoziziritsira zoziziritsa ku sitolo ya 4S.Kufotokozera kwachitsanzo chotsatirachi:

Yankholi mosakayika ndi yankho loyenera kukhathamiritsa.Pamene chilimwe chitentha m'chilimwe, kuphatikiza firiji ndi fani yaikulu ingagwiritsidwe ntchito kuti akwaniritse mpweya wabwino komanso kuzizira.Magalimoto amkati amatha kuyatsidwa m'dzinja mwachindunji.Pa nthawi yomweyi, mpweya wabwino umasungabe kuzizira kwina.Akatswiri okonza magalimoto ndiye maziko a ntchito komanso phindu.Ogwira ntchito zaluso ayenera kuwongolera kulemba anthu ntchito ndikusunga anthu ndikuwongolera malo ogwirira ntchito.Mosakayikira ndi njira yabwino yolembera antchito.Mtengo wapadera.
