Imeko ngokubanzi yophuhliso lomoya wokufuduka

Kwiminyaka yakutshanje, indlela entsha yokungenisa umoya, ukufuduswa komoya, iye yatsala umdla wabayili kunye nabanini kwilizwe lam. Xa kuthelekiswa nendlela yokungenisa umoya exutyiweyo, le ndlela yokuhambisa umoya yenza ukuba indawo yokusebenza yangaphakathi ifumane umgangatho ophezulu womoya, intuthuzelo yobushushu obuphezulu kunye nokusebenza kakuhle kokungena komoya. Ngowe-1978, isiseko saseBerlin, eJamani samkela inkqubo yokukhupha umoya okwesihlandlo sokuqala. Ukusukela ngoko, inkqubo yokuphuma komoya yokufuduswa iye yasetyenziswa ngokuthe ngcembe kwizakhiwo zoshishino, izakhiwo zoluntu kunye nezakhiwo zikawonke-wonke. Ngokukodwa kumazwe aseNordic, malunga ne-60% yeenkqubo zokungenisa umoya kwimizi-mveliso ngoku zisebenzisa iinkqubo zokufudumeza umoya; malunga ne-25% yeenkqubo zokungena komoya kwiiofisi zisebenzisa iinkqubo zokufudumeza umoya.

Intshayelelo kumgaqo-siseko wokufuduswa komoya

I-ventilation yokufuduka iqondisa umoya omtsha kwindawo yokusebenza kwaye idala ichibi lomoya elincinci emgangathweni. Amachibi omoya enziwa kukusasazwa komoya opholileyo. Imithombo yobushushu (abantu kunye nezixhobo) kwigumbi ivelisa ukugeleza komoya onyukayo. Ngenxa ye-buoyancy yomthombo wokushisa, umoya omtsha ugeleza kwindawo ephezulu yegumbi kwaye ukhokelela kumoya olawulayo wentshukumo yomoya wangaphakathi. Imibhobho yokukhupha umoya ibekwe phezulu kwigumbi kwaye ikhuphe umoya ongcolileyo. Ubushushu bomoya ococekileyo obundliwa kwigumbi ngamaziko okubonelela ngokuqhelekileyo buphantsi kunobushushu bendawo yokusebenza yangaphakathi. Iyatshona kumphezulu ngenxa yokuxinana komoya opholileyo. Isantya sokuhanjiswa komoya sokufuduswa komoya simalunga ne-0.25m/s. Isantya somoya wonikezelo siphantsi kangangokuba asinayo nayiphi na impembelelo ebonakalayo ekuhambeni komoya okhoyo kwigumbi. Umoya opholileyo opholileyo unwenwela kuwo wonke umgangatho wangaphakathi njengokugalela amanzi kwaye ukhokelela kwichibi lomoya. I-airconvection convection airflow ebangelwa ngumthombo wobushushu yenza i-gradient yobushushu obuthe nkqo kwigumbi. Kule meko, ukushisa komoya womoya wokukhupha kuphezulu kunokushisa okusebenzayo ngaphakathi. Ingabonwa ukuba ukuhamba komoya okubalaseleyo kokuphuma komoya kulawulwa ngumthombo wobushushu wangaphakathi. Ngoko ke, olu hlobo lokungenisa umoya lukwabizwa ngokuba yi-heat displacement ventilation.
