Esi sicwangciso ngamabomu sinceda ukugcina i-laminar kunye ne-airflow efanayo, ukuqinisekisa ukusebenza kwezixhobo ze-IT zokupholisa. Ingcamango yokwakha Kwiparadigm yokupholisa yasimahla, imibhobho yomoya yemveli ayisetyenziswanga ngaphakathi kwesakhiwo sesakhiwo. Ngokungafani neeseti eziqhelekileyo ezinemibhobho yomoya echongiweyo kwiindonga, iisilingi, okanye iindawo ezithile, amaziko okucubungula idatha athatha indlela engaqhelekanga. Isakhiwo ngokwaso sithathwa njengombhobho womoya, unikezela iiyunithi zesiqhelo zokupholisa umoya ukuba ziphelelwe lixesha. Umlinganiselo omkhulu wale mibhobho yomoya uyiguqula ibe ngamacandelo adibeneyo amagumbi kunye nemigangatho. Inkqubo yokuhamba komoya iqala njengoko umoya wangaphandle ungena kwisakhiwo, udlula kwiintlobo ezimbini zeefilitha - izihlungi ezinqabileyo kunye nezihlunu ezintle. Nje ukuba umoya uqhube inkqubo yokucoca, uqhutywa ngabalandeli ukuya kwimithamo ebanzi yokwakha, ephantse ilingane nemigangatho emine ukuphakama. Lo mthamo omkhulu usebenzela injongo yawo: ukunciphisa ukuhamba komoya, ukunciphisa isantya sawo kuluhlu olufunekayo lweemitha ezili-1-2 ngesekhondi. Emva koko, umoya wehlela kwigumbi lomatshini. Emva kokutyhutyha igumbi lomatshini, umoya uqhubeka nohambo lwawo kwii-racks ze-IT, uqhubela phambili kwi-aisle eshushu. Ukusuka apho, ingena kumqokeleli womoya oshushu ngaphambi kokuba igxothwe ngaphandle ngabalandeli be-exhaust. Le ndlela yomoya eyakhiweyo iqinisekisa inkqubo epholileyo yokupholisa ngelixa igcina isantya somoya esilawulwayo. Isantya somoya kunye neVolume Uyilo olwenziwa ngabom lokusebenzisa umthamo wolwakhiwo olwandisiweyo luneenjongo ezimbini. Okokuqala nokuphambili, ivumela ukunciphisa ngokuthe ngcembe kwi-airspeed, ukuqinisekisa ukuba ukuhamba komoya kufezekisa isantya esifunwayo se-1-2 yeemitha ngomzuzwana. Le santya somoya esilawulwayo siyimfuneko ekuthinteleni isiphithiphithi kunye nokugcina ukuhamba kwe-laminar, kubaluleke ngakumbi njengoko umoya uqhubela phambili ngokusebenzisa izixhobo ze-IT ezibuthathaka. Okwesibini, umthamo obalulekileyo uvumela umthamo womoya ofunekayo ukuze uchithe ubushushu obuveliswayo ngokufanelekileyo.
