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 wakakura ndewekuti tinoenda sei pakupa mweya weokisijeni wakakwana wekuvaka vagari uku tichichengetedza mazinga akaderedzwa eHVAC mashandisirwo emagetsi sekurairwa nemirairo yehurumende iripo.
Kufemerwa nekudonha-kubuda kweiyo embargo yemafuta mukutanga 1970s, iyo US Dhipatimendi reMagetsi (DOE) yakatanga chirongwa chese chekuchengetedza simba icho chakatungamira kuNorth America maregulator kugadzira inogara ichiwedzera HVAC miitiro inoshanda kana Minimum Efficiency Performance Standards. (MEPS).
Pamwe pamwe nemagetsi akawandisa eHVAC mamwe maitiro akonzera kuvhara dzimba dzakasimba sezvinobvira nemahwindo akasimba, magonhi, zvipingamupinyi zvemhute uye magaba ekuwedzera furo insulation.
Mune imwe ongororo yenguva ye90's era yekugadziridzwa kwekugara, imba iri kutaurwa yakadzvinyirirwa kupfuura 50 pascals kamwe chete midziyo inonetesa mhepo (mafeni ekugezera, kicheni siyana hood) ichimhanya.Ndizvo zvakapetwa ka10 depressurization pane inobvumirwa, kunyanya ne buoyancy vented fossil-fueled midziyo mukati mechimiro.Tinoda mweya!
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 kunyorova, kunhuhwirira, carbon dioxide, ozone, particulates uye mamwe makemikari anokuvadza.Uye uku kuvhura hwindo kunopa mhepo inodiwa yekufemesa, uku kufefetedza kusingadzorerwe kuchaita kuti masisitimu eHVAC apedze simba rakawandisa - simba ratiri kufanira kuchengetedza.
Make-up mhepo imhepo inopinda ichibva kunze yakanangana kutsiva mweya iwoyo uri kupera nemidziyo yakaita semahodhi emhando uye mafeni ekugezera, yepakati vacuum masisitimu uye zvekuomesa mbatya.Dzimba dzemazuva ano dzakavakwa nemakodhi achangoburwa pamwe hadzichadi mhepo yekugadzira kunze kunze kwekunge mahodhi akakura achifamba anofambisa mavhoriyamu makuru emhepo (anopfuura mazana maviri cfm) akaiswa nevabiki vanoshingaira.
Pakupedzisira, kunewo mhepo inopisa, mhepo yaifanirwa kushandiswa nemidziyo yefossil-fuel yakadai semavira egasi, zvidziva zvemvura, zvitofu uye huni dzinopisa moto.Nokuzadza gaka rose rinofungidzirwa rekubvinza kwemhepo mudzimba dzanhasi, midziyo yegasi inofanira “kukwereta” mweya wekufema nokudaro zvichikonzera dambudziko rine njodzi.Midziyo isingakwanise kubuda nekuda kwedepressurization, kana nzara yemhepo, inogona kutanga kupisa zvigadzirwa zvayo zveflue zvichigadzira zvinouraya kabhoni monoxide, dambudziko rakapedza hupenyu hwevanhu vakawandisa mumakore apfuura.

Zvivako zvekare zvainyudza zvekuti mweya waipinda waizadzisa zvese zvinodiwa zvekufemesa zviri nyore, asi kwete pasina zvirango.Mhepo yaipinda yaida kugadziriswa nekupisa uye pamwe hunyoro hunowedzera mari yehuturu nekugadzirisa.Dzimba dzaive dzakapfava, vanogaramo vaiwanzonzwa kusagadzikana sezvo mhepo yakaoma yaibuda yakawandisa yehunyoro kubva paganda ichigadzira kunzwa kwekunyanya kutonhora.Kuvakwa kwemagetsi mumakapeti nemidziyo kwakakonzera kuvhunduka kunorwadza apo muridzi wemba akachajiswa magetsi akabata pasi.Saka, ndezvipi zviri nani?
A heat recovery ventilator (HRV) is a mechanic ventilation solution iyo inoshandisa stale exhaust airstream preheat the same volume yechando ichipinda kunze kwemhepo yakachena.
Sezvo mafungu emhepo achipfuura pakati pepakati peHRV, inopfuura 75% kana zvirinani yekupisa kwemhepo yemukati ichaendeswa kumhepo inotonhora nokudaro ichipa mhepo inodiwa ichideredza mutengo we "kugadzira" kupisa kunodiwa kuunza izvo. mweya mutsva kusvika kune ambient room tembiricha.
Mune humid geographies, mumwedzi yezhizha HRV ichawedzera 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 nehunyoro hwekuwedzera, zvinobvumwa, nemutengo wakawedzerwa.
An energy recovery ventilator (ERV), inoshanda nenzira yakafanana neyeHRV, asi munguva yechando humwe hunyoro hwemhepo hunodzoserwa munzvimbo yemukati.Sezvinei, mudzimba dzakasimba, ERV ichabatsira kuchengetedza mwando wemukati muchikamu che40% zvichipikisa 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.
