Ngokuhamba kweminyaka, amathani ocwaningo akhombisa izinzuzo zokwandisa umthamo wokungenisa umoya ngaphezu kwesilinganiso esincane sase-US (20CFM/Umuntu), okuhlanganisa ukukhiqiza, ukuqonda, impilo yomzimba kanye nekhwalithi yokulala. Kodwa-ke, izinga eliphezulu lokungenisa umoya lamukelwa kuphela engxenyeni encane yezakhiwo ezintsha nezikhona. Kulo mbhalo, sizokhuluma ngezithiyo ezimbili eziyinhloko zokukhuthaza izinga eliphezulu lokungenisa umoya, okungokomnotho kanye nemvelo.
Ake sijule ndawonye!
Eyokuqala, singayihumushela ezindlekweni zokwamukela izinga eliphezulu le-IAQ. Izinga eliphakeme lizosho abalandeli bokungenisa umoya abaningi noma abakhulu, ngakho-ke ngokuvamile sivame ukukholelwa ukuthi kuzodla amandla amaningi. Kodwa, akunjalo. Bona ithebula elingezansi:
Kusuka ku-“Imithelela Yezomnotho, Eyemvelo kanye Nezempilo Yokungenisa Umoya Okuthuthukisiwe Ezakhiweni Zamahhovisi, nge Piers MacNaughton, James Pegues, Usha Satish, Suresh Santanam, John Spengler noJoseph Allen”
20CFM/umuntu kuzoba umugqa wethu osuselwe; khona-ke izindleko zonyaka zokusetshenziswa kwamandla kwenani elikhulayo lokungenisa umoya zibalwa ngokwesilinganiso sasendaweni futhi ziqhathaniswe nedatha yethu yomugqa esekelwe. Njengoba ubona, ukwandisa izinga lokungena komoya ngo-30% noma kabili, izindleko zamandla zizokhuphuka kancane ngonyaka, okungezona izinkulungwane zamaRandi esivame ukukholelwa. Ngaphezu kwalokho, uma sethula i-ERV esakhiweni, izindleko zizoba ngaphansi noma ngaphansi kwezindleko zangempela!
Okwesibili, imvelo, kusho umthelela wemvelo wokwandisa izinga lokungena komoya. Ake sibone ithebula elingezansi ukuze siqhathanise i-emission:
Kusuka ku-“Imithelela Yezomnotho, Eyemvelo kanye Nezempilo Yokungenisa Umoya Okuthuthukisiwe Ezakhiweni Zamahhovisi, nge Piers MacNaughton, James Pegues, Usha Satish, Suresh Santanam, John Spengler noJoseph Allen”
Ngokufanayo nezindleko, idatha ye-20CFM/umuntu izoba umugqa wethu osuselwe; bese uqhathanisa ukuphuma kwabo. Yebo, akungabazeki ukuthi ukwandisa izinga lokungena komoya kuzophinde kwandise ukusetshenziswa kwamandla esimweni esivamile, ngakho-ke ukwandisa ukukhishwa kwe-CO2, i-SO2 ne-NOx. Kodwa-ke, uma sethula i-ERV esivivinyweni, indawo ezungezile izosuswa!
Kusukela olwazini olungenhla, ungabona ukuthi izindleko nomthelela wokunyusa izinga lokungena komoya esakhiweni kwamukeleka kakhulu, ikakhulukazi uma i-ERV yethulwa ohlelweni. Empeleni, lezi zici ezimbili zibuthakathaka kakhulu ukuba zingasivimba. Okubonakala kuyisithiyo ngempela ukuthi asinawo umqondo ocacile wokuthi i-IAQ ephakeme inganikela ngani! Lezi zinzuzo zidlula kude izindleko zomnotho zomuntu ngamunye. Ngakho, ngizokhuluma ngalezi zinzuzo ngamunye ngamunye ezihlokweni zami ezilandelayo.
Kwangathi ungaba nomoya omusha nonempilo nsuku zonke!
