Kwemakore, matani ekutsvagisa anoratidza mabhenefiti ekuwedzera vhoriyamu yekufefetera pamusoro pehushoma hweUS mwero (20CFM/Munhu), kusanganisira kubereka, kuziva, hutano hwemuviri uye kunaka kwekurara. Nekudaro, yakakwira kufefetera mwero inongogamuchirwa muchikamu chidiki chezvivakwa zvitsva uye zviripo. Muchinyorwa ichi, tichataura pamusoro pezvipingamupinyi zviviri zvikuru zvekusimudzira chiyero chepamusoro chekufemesa, izvo zvehupfumi uye zvakatipoteredza.
Ngaticherei zvakadzama pamwechete!
Yekutanga, tinogona kuidudzira mumutengo wekutora yepamusoro IAQ standard. Yepamusoro mwero inozoreva yakawanda kana yakakura kufefetera mafeni, saka kazhinji isu tinowanzo kutenda kuti ichapedza rakawanda simba. Asi, hazvisi. Ona tafura iri pasi apa:

20CFM/munhu achava mutsara wedu wakavakirwa; zvino mutengo wepagore wekushandiswa kwesimba kwekuwedzera kwemhepo yemhepo inoverengerwa zvichienderana nereti yenzvimbo uye ichienzaniswa neyedu yakavakirwa mutsara data. Sezvauri kuona, kuwedzera kufefetedza kwemhepo ne30% kana kupetwa kaviri, mutengo wesimba unongowedzera zvishoma pagore, izvo zvisiri zviuru zvemadhora izvo isu tinowanzo kutenda. Uyezve, kana tikaunza ERV muchivako, mutengo uchave wakaderera kana kutoderera pane mutengo wekutanga!
Chechipiri, zvakatipoteredza, zvinoreva kukanganisa kwezvakatipoteredza kwekuwedzera mwero wemhepo. Ngationei pazasi tafura yekuenzanisa emission:

Zvakafanana nemutengo, data ye20CFM / munhu ichave yedu yakavakirwa mutsara; wobva waenzanisa kuburitsa kwavo. Hongu, hapana kupokana kuti kuwedzera chiyero chekufemesa kuchawedzerawo kushandiswa kwesimba mune yakajairika kesi, saka kuwedzera kubuda kwe CO2, SO2 uye NOx. Nekudaro, kana tikasuma ERV mukuyedza, nharaunda inozove isina kwayakarerekera!
Kubva pane ruzivo rwuri pamusoro apa, unogona kuona kuti mutengo uye kukanganisa kwekuwedzera chiyero chemhepo kune chivakwa chinogamuchirwa zvakanyanya, kunyanya kana ERV ikaunzwa muhurongwa. Chaizvoizvo, zvinhu zviviri izvi hazvina kusimba kuti zvitimise. Chinonyatsoita sechipingamupinyi ndechekuti isu hatina pfungwa yakajeka yezvipi zvakakwirira zveIAQ zvinogona kubatsira! Mabhenefiti aya anopfuura nekure mutengo wehupfumi hwemunhu. Nokudaro, ndichataura pamusoro peizvi zvikomborero chimwe nechimwe munyaya dzangu dzinotevera.
Dai uine mweya mutsva uye une hutano mazuva ese!
