Ngokuthuthuka kwamazinga okuphila, izidingo zabantu ngendawo yokuhlala nazo ziyanda, futhi imindeni eminingi izosebenzisa izinto zokuhlanza umoya ukuze ihlanze umoya wasendlini.Esikhathini sokusebenzisa, abantu abaningi bazobuza umbuzo: Ingabe i-isihlanzi somoyakufanele uhlale ngaso sonke isikhathi?Ifaneleka isikhathi esingakanani?
Izihlanzi zomoya zingasefa i-PM2.5, uthuli, nezinto ezingezwani nazo emoyeni wasendlini.Abanyeabahlanza umoyafuthi ibe nemisebenzi ekhethekile, njengokuvala inzalo nokubulala amagciwane noma ukuhlunga okuhlosiwe kokungcolisa okuthile.Abanye abantu bathi isihlanzi somoya kufanele sivulwe amahora angu-24 ukuze kuqinisekiswe ukuthi umoya osekhaya uhlezi uhlanzekile.
Abanye abantu bathi isihlanzi somoya akufanele sishiywe ngaso sonke isikhathi, ngoba lokhu kumosha kakhulu ugesi, futhi isihlungi sisebenzisa ngokushesha kakhulu, futhi izindleko zokushintshwa ziphezulu kakhulu, okuzokwandisa umthwalo wezomnotho;noma ukhathazeke ngokuthi umshini uzofinyeza impilo yesevisi uma ugcinwa uvuliwe.
Isihlanzi somoya sisetshenziswa ekamelweni elivaliwe.Isimiso sayo sokusebenza isimiso sokujikeleza kwangaphakathi, esihlanza umoya wangaphakathi wangaphakathi.Umshini udonsa umoya ongaphakathi emshinini ngokusebenzisa i-air inlet ukuze ucwenge futhi uhlanzwe, bese ukhipha umoya ohlungiwe nge-outlet yomoya, onganciphisa ngempumelelo izinto eziyingozi ezifana ne-PM2.5 kanye nephunga elingavamile ekamelweni.Lo mjikelezo ufeza injongo yokuhlanza umoya.Indlela yomoya ecutshungulwa isihlanzi somoya ithi: ngaphakathi.
Kusho ukuthini lokhu?Kusho ukuthi uma isihlanzi somoya sisetshenziswa isikhathi eside, ukugcwala kwe-carbon dioxide emoyeni wasendlini kuzoqhubeka nokukhula, futhi umoya-mpilo ngeke unele, ukuze umoya oshisayo ube yingozi empilweni yomuntu.
Abanye abantu bangase baphikise ngokuthi indlu ayivalwanga ngokuphelele, futhi kuzoba nezikhala phakathi kweminyango namafasitela, ngakho-ke umoya wangaphandle nomoya wangaphakathi kusengashintshaniswa.Kodwa-ke, izinga lokushintshisana elinjalo elingenamsebenzi alikwazi ukuhlangabezana nezidingo zokuphefumula okunempilo komzimba womuntu, futhi okuqukethwe kwe-carbon dioxide endlini kuzoqhubeka nokukhula.
Ngakho-ke, awukwazi ukugcina i-isihlanzi somoyaku.Ngemuva kwesikhathi sokusebenzisa, kufanele uvule amafasitela ukuze kungene umoya ukuze uqinisekise ukusha komoya wasendlini.Ngokuqondene nokuthi kuthatha isikhathi esingakanani ukukhipha umoya, kuncike kakhulu eqophelweni lomoya wendawo, ubukhulu bendawo yasendlini, inani labantu, kanye nezinga lokunukubezeka komoya endlini.
