Isimo esijwayelekile sokuthuthukiswa kwe-ventilation yokufuduka

Eminyakeni yamuva nje, indlela entsha yokungenisa umoya, ukufuduka komoya, iye yakhanga kakhulu ukunaka kwabaklami nabanikazi ezweni lami. Uma kuqhathaniswa nendlela yendabuko yokufaka umoya exubile, le ndlela yokuhlinzeka komoya yenza indawo yokusebenza yasendlini ithole izinga eliphezulu lomoya, ukunethezeka okuphezulu kokushisa kanye nokusebenza kahle komoya okuphezulu. Ngo-1978, indawo esungulwe eBerlin, eJalimane yamukela uhlelo lokufudumeza komoya okokuqala ngqa. Kusukela lapho, uhlelo lokungena komoya lokufuduka luye lwasetshenziswa kancane kancane ezakhiweni zezimboni, izakhiwo zomphakathi kanye nezakhiwo zomphakathi. Ikakhulukazi emazweni aseNordic, cishe amaphesenti angu-60 wezinhlelo zokungenisa umoya ezimbonini manje zisebenzisa amasistimu okungenisa umoya wokufuduka; cishe u-25% wezinhlelo zokungenisa umoya ehhovisi zisebenzisa amasistimu okungenisa umoya okususwayo.

Isingeniso somgomo wokukhipha umoya omncane

Ukungenisa komoya okususwayo kuqondisa umoya omusha endaweni yokusebenza futhi kwakha ichibi lomoya elincanyana phansi. Amachibi omoya akhiwa ngokusakazwa komoya opholile opholile. Imithombo yokushisa (abantu nemishini) esegunjini ikhiqiza ukugeleza komoya okhuphukayo okhuphukayo. Ngenxa yokugcwala komthombo wokushisa, umoya ohlanzekile ugeleza uye engxenyeni engenhla yegumbi futhi uholela ekugelezeni komoya okubusayo kokuhamba komoya wasendlini. Izimbobo zokukhipha umoya zibekwe phezulu kwegumbi futhi zikhiphe umoya ongcolile. Izinga lokushisa lomoya omusha ofakwe ekamelweni ngamapayipi okuhlinzeka ngokuvamile liphansi kunezinga lokushisa lendawo yokusebenza yasendlini. Ishona phezulu ngenxa yokuminyana komoya opholile. Isivinini sokuphakelwa komoya sokungenisa komoya osuswayo sicishe sibe ngu-0.25m/s. Umfutho womoya wokuhlinzeka uphansi kangangokuthi awunawo umphumela ongokoqobo ekugelezeni komoya okukhona ekamelweni. Umoya opholile opholile usakazeka phezu kwendawo yonke yasendlini njengokuthela amanzi futhi uholela echibini lomoya. Ukugeleza komoya kwe-convection eshisayo okubangelwa umthombo wokushisa kudala i-gradient eqondile yezinga lokushisa ekamelweni. Kulokhu, izinga lokushisa lomoya lokukhipha umoya liphakeme kunokushisa okusebenzayo kwangaphakathi. Kuyabonakala ukuthi ukugeleza komoya okubusayo kokungenisa komoya okususwayo kulawulwa umthombo wokushisa wasendlini. Ngakho-ke, lolu hlobo lwe-ventilation lubizwa nangokuthi i-heat displacement ventilation.
