Sezvo miitiro mitsva yekodhi yekuvaka ichitungamira kune dzakasimba mahamvuropu ekuvaka, dzimba dziri kuda michina yekufemesa mhepo kuitira kuchengetedza mweya wemukati mutsva.
Mhinduro iri nyore kumusoro wechinyorwa ichi ndewemunhu wese (munhu kana mhuka) anogara nekushanda mumba. Mubvunzo muhombe ndewekuti tinoenda sei pakupa mweya weokisijeni wakakwana wekuvaka vagari tichichengetedza mazinga akaderedzwa eHVAC mashandisirwo emagetsi sekurairwa nemirairo yehurumende iripo.
Mhepo Yerudzii?
Nemahamvuropu ekuvaka emazuva ano akasimba isu tinofanirwa kufunga nezvekuunza mweya mukati uye nei. Uye tingangoda marudzi akati wandei emhepo. Kazhinji kunongova nemhando imwe chete yemhepo, asi mukati mechivako tinoda mweya wekuita zvinhu zvakasiyana zvichienderana nemabasa edu emukati.
Mhepo yekufemesa ndiyo inonyanya kukosha kune vanhu nemhuka. Vanhu vanofema mamwe 30 lbs. yemhepo zuva nezuva isu tichipedza ingangoita 90% yehupenyu hwedu tiri mumba. Panguva imwecheteyo, zvakakosha kubvisa unyoro hwakawandisa, kunhuhwirira, carbon dioxide, ozone, particulates uye mamwe makemikari anokuvadza. Uye nekuvhura hwindo kunopa mhepo inodiwa yekufemesa, uku kufefetedza kusingadzoreki kuchaita kuti masisitimu eHVAC apedze simba rakawandisa - simba ratiri kufanira kuchengetedza.
Mechanical Ventilation
Dzimba dzemazuvano uye zvivakwa zvekutengesa zvinobhadhara zvakanyanya kumhepo uye hunyoro hunopinda mukati kana kunze kwechivako, uye nezviyero zvakaita seLEED, Passive House neNet Zero, dzimba dzakasimba uye envelopu yekuvaka yakavharwa nechinangwa chekudonha kwemhepo. kwete kupfuura 1ACH50 (imwe shanduko yemhepo paawa pa50 pascals). Ndakaona mumwe mubatsiri wePassive House achizvikudza nezve 0.14ACH50.
Uye masisitimu emazuva ano eHVAC akagadzirwa zvirinani ane zvitofu zvegasi uye maheater emvura achishandisa mweya wekunze wekupisa, saka hupenyu hwakanaka, kwete? Zvimwe hazvina kunaka, sezvo tichiri kuona mitemo yezvigunwe ichiita kutenderera kunyanya mumabasa ekugadzirisa uko masisitimu emhepo anowanzo kuwandisa, uye mahodhi ane simba emhando yepamusoro anogona kuramba achiyamwa angangoita mamorekuru ese emhepo kunze kwemba achimanikidza vangave-vabiki kuti vavhure. hwindo.
Kusuma HRV uye ERV
A heat recovery ventilator (HRV) is a mechanic ventilation solution iyo inoshandisa stale exhaust air stream preheat the same volume yekutonhora kupinda kunze kwemhepo yakachena.
Sezvo nzizi dzemhepo dzichipfuura pakati pepakati peHRV, inosvika makumi manomwe neshanu muzana kana zvirinani zvekupisa kwemukati memukati kunoendeswa kumhepo inotonhora zvichipa mhepo inodiwa uku ichideredza mutengo we "kugadzira" kupisa kunodiwa kuunza. iyo mweya mutsva kusvika kune ambient kamuri tembiricha.
Mune humid geographies, mumwedzi yezhizha HRV inowedzera humidity level mumba. Nekutonhora kuri kushanda uye mahwindo akavharwa, imba ichiri kuda mhepo yakakwana. Iyo yakanyatso saizi yekutonhodza sisitimu yakagadzirwa nechirimo yakadzika mutoro mundangariro inofanirwa kukwanisa kubata nehumwe hunyoro, zvinobvumwa, nemutengo wakawedzerwa.
ERV, kana simba rekudzorera mhepo, rinoshanda nenzira yakafanana neHRV, asi munguva yechando humwe hunyoro huri mumhepo hunodzorerwa munzvimbo yemukati. Sezvineiwo, mudzimba dzakasimba, ERV ichabatsira kuchengetedza mwando wemukati muchikamu che40% kupikisa kusagadzikana uye kusaita hutano hwemhepo yakaoma munguva yechando.
Kuvhiya kweZhizha kunoita kuti ERV irambe kusvika 70% yehunyoro iri kuuya ichiidzosera kunze isati yagona kurodha-update system. ERV haiite se dehumidifier.

Installation Kufunga
Nepo ERV/HRV mayunitsi akagadzirirwa kuiswa kwekugara anogona kuiswa mune yakapfava fashoni uchishandisa iripo mhepo yekubata system kugovera mhepo ine conditioned, usaite saizvozvo kana zvichiita.
Sekuona kwangu, zvakanakisa kuisa yakazvipira zvizere duct system mukuvaka kutsva kana kupedzisa mabasa ekugadzirisa. Chivako chinozobatsirwa kubva kune yakanakisa conditioned air kugovera uye yakaderera inogoneka mutengo wekushandisa, sezvo choto kana mhepo inobata fan isingazodiwi. Heino Muenzaniso wekumisikidzwa kweHRV nebasa rakananga duct. (chibviro: NRCan Publication (2012): Heat Recovery Ventilators)
