Ukuze uzive ukhululekile kwaye ukhululekile kwikhaya lakhe kwaye unandiphe umoya ococekileyo, i-ventila esemgangathweni ephakathi kunye nemeko yomoya iyafuneka. Kunokwenzeka kuphela ukuba inkqubo ibonelelwe ngokuhamba okuqhelekileyo kweoksijini.
Iskimu se-ducts ventilation ducts: 1 - fan; 2 -ahloka; 3 -ukudideka; I-4-Cross; I-5-tee; I-6-Isuswa; Ukukhula kwesi-7 ngequbuliso; 8 I-Valling-dabs; 9 - Idolo; 10 -Nganyatha isiquphe; I-11, iguquguqukayo i-lolly tices; I-12-Inqwelomoya yenqwelomoya.
Utshintshiselwano olufanelekileyo lwenkqubo, ukubalwa kwe-aerodynamic ye-ducts zomoya kuyafuneka kuyilo lwenkqubo yenkqubo yokufihlakeleyo.
Umoya ohamba ecaleni kweendlela zomoya uthathwa njenge-fluid engacacanga. Oku kucingelwa kunokwenzeka, kuba uxinzelelo olukhulu aluvunyelwanga kwiindawo zomoya. Ingcinezelo yenziwa ngokungqinelana kobunzima bomoya kubuncwane bejelo, kwaye xa imvumelwano yendawo yenzeka, xa idlulise imilambo, xa i-Deameter Channel itshintshiwe, okanye Kwindawo yokufakwa kwezixhobo zolawulo.
Ukubala ukubala i-Aerodynamic kubandakanya inkcazo yobungakanani bamacandelo ayo yonke imimandla yenethiwekhi ye-ventilation, eqinisekisa ukuhamba kwenani lomoya. Ukongeza, kuyimfuneko ukufumanisa ukukhutshwa okwenzekayo xa i-supers ye-moya ihamba.
Iskimu sokudala umoya ovuthuzayo wendalo.
Njengokuziqhelanisa nokuziqhelanisa, ngamanye amaxesha ekubaleni, amanye amaxabiso adwelisiweyo sele ezaziwe. Ezi meko zilandelayo zifunyenwe:
- Uxinzelelo luyaziwa, kuyimfuneko ukubala icandelo lomnqamlezo wemibhobho yokuqinisekisa intshukumo yexabiso leoksijini. Le meko ingumlinganiswa weenkqubo zokwehla zendalo, xa uxinzelelo lokulahla olungenakutshintshwa.
- Icandelo lomnqamlezo seziteshi kwinethiwekhi liyaziwa, kuyimfuneko ukubala uxinzelelo oluyimfuneko ekuhambiseni inani elifunekayo legesi. Iimpawu zezo nkqubo ze-ventilations ezinamacandelo anqamlezileyo zibangelwa kukakhiwo okanye iimpawu zobuchwephesha.
- Akukho nanye yezinto eziguquguqukayo engaziwa, ke iyimfuneko ukubala icandelo lomnqamlezo kunye noxinzelelo kwinkqubo yokufihlakeleyo. Le meko yeyona ixhaphakileyo kwisakhiwo sendlu.

I-Aerodynamiting Calm
Cinga ngeyona ndlela iyonke yokubala i-aerodynamic ukubala kwingcinezelo engaziwayo kunye namacandelo. Ukubala i-aerodynamic kwenziwa emva kokuba inani elifunekayo lomoya limisiwe, nto leyo ekufuneka igqithile kwinethiwekhi yokuthwalela imeko, kunye nendawo eqikelelweyo yenkqubo ye-moya yenziwa.
Isekethe ye-ventilation exutywe.
Ukubala, iskimu se-AXONometric siyatsalwa, apho uluhlu kunye nobungakanani bazo zonke izinto zenkqubo zibonisiwe. Ngokwenkqubo yokufihlakeleyo, ubude bonke bemigca yomoya bugqityiwe. Okulandelayo, inkqubo ye-ducts zomoya yahlulahlulwe yangamacandelo e-homogeneous, apho ukuhamba komoya kugqitywa ngokwahlukeneyo. Ukubala i-aerodynamic yenzelwe indawo nganye yenethiwekhi yenethiwekhi, apho kukho ukusetyenziswa rhoqo kunye nobunzima bomoya. Yonke idatha ebaliweyo isetyenziswa kwiskimu se-axonometric, emva koko kwenziwe ngendlela ephambili.
Ukufumanisa isantya kwiziteshi
Njengoko eyona ndlela iphambili, olona nyango luyekisiweyo lwamacandelo e-serial yenkqubo anyuliweyo, abalwa kude. Iiparamitha zendawo nganye (inani, ubude bendawo, ukusetyenziswa komoya) zirekhodwa kwitheyibhile yobalo. Emva koko, khetha ubume becandelo lomnqamlezo kwaye ubale imilinganiselo yamacandelo.
Indawo enqamlezileyo yecandelo lomgca wendlela enkulu ibalwa yifomula:
Fp = lp / vt,
apho iFP yindawo enqamlezileyo yecandelo, m2; I-LP-Ukusetyenziswa komoya kwisiza, m3 / s; I-VT-isantya sokuhamba kwegesi kwicandelo, m / s. Isantya sentshukumo simiselwe ngokuqwalaselwa kwengxolo yenkqubo yonke kunye nokuqwalaselwa kwezoqoqosho.
Iskimu se-ventilation ekhaya.
Ngokwecandelo elifunyenweyo, i-duct yobukhulu obuqhelekileyo ikhethiwe, apho icandelo lomnqamlezo (FF) likufuphi nokubalwa.
Ngokweyona ndawo iyona, isantya sentshukumo sibalwa kwindawo:
Vf = lp / ff
Ngokusekwe kwesi santya, iitafile ezikhethekileyo zibala ukwehla koxinzelelo kwiindonga zezifundo zeenqwelomoya. Izivumelwano zalapha ekhaya zimiselwa kwindawo nganye kwaye ziyashwankathelwa kwixabiso ngokubanzi. Isixa selahleko ngenxa yokuphoxwa nokungaxhathiswa kwendawo lixabiso elipheleleyo lelahleko kwinethiwekhi yenethiwekhi ebonakalayo, ethathiweyo ukubala inani elifunekayo lomoya kwiziteshi ezifunekayo.

Ukubalwa koxinzelelo kwindawo enkulu
Uxinzelelo lokulahla indawo kwindawo nganye yendlela enkulu ibalwa yifomula:I-DPE = h * g (PH-PB),
Apho i-DPE iluxinzelelo lwendalo, i-PA; H - Umahluko kumanqaku eengcingo zengcingo kunye nomlomo wezam, m; Ph kunye ne-PB-igesi yegesi ngaphandle nangaphakathi kwe-ventilation, ngokulandelelana, kg / m3.
Ukuxinana ngaphandle nangaphandle kumiselwe ziitafile zenkcazo ngokusekwe kubushushu bangaphandle kunye nobushushu bangaphakathi. Ngokwesiqhelo, iqondo lobushushu langaphandle lithathiwe njenge- + 5 ° C, nokuba yeyiphi indawo yokwakha. Ukuba iqondo lobushushu langaphandle liphantsi, inaliti kwinkqubo yonyuka, ekhokelela kwivolumu yomoya ongenayo. Ukuba iqondo lobushushu langaphandle liphezulu, ingcinezelo kwinkqubo incitshisiwe, kodwa le meko ibuyiselwe zii-chants ezivulekileyo okanye iifestile.
Owona msebenzi ophambili wokubala i-aerodynamic kukhetho lwezinto ezinjalo apho ilahleko (σ (r * l * + z) ziya kulingana okanye zingaphantsi kweDPE:
Σ (r * l * + z) ≤ DE,
Apho yilahleko ye-filtions, p / m; Ngaba ubude bendawo, m; β-ukulingana kweendonga zodonga lokukhanya; Z-ukunciphisa ireyithi yerhasi ukusuka ekungaxhathisi kwasekuhlaleni.
Ixabiso lokuqhekeka β lixhomekeke kwinto eyenziwe ngayo amajelo.

Isitokhwe siyacetyiswa ukuba sithathelwe ingqalelo kwi-10 ukuya kwi-15%.
Ukubala ngokubanzi I-Aerodynamic
Kwibabalo le-aerodynamic, zonke iiparameter zemigodi ye-winntilation ithathelwa ingqalelo:
- Ukuhamba komoya l, m3 / h.
- Ububanzi beDucc D, mm, ezibalwa yiFomula: D = 2 * A * B / (A + B), apho i-A kunye ne-A kunye ne-A kunye ne-MM.
- Isantya v, m / s.
- Ilahleko yokulahleka kwe-factions r, p / m.
- Uxinzelelo lwe-Dynamic p = DPE2 / 2.
Ukubala kwenziwa kwijelo ngasinye kule dilesi ilandelayo:
- Indawo yokusebenza efunekayo igqityiwe: F = l / (3600 * vrek), apho i-F-indawo, m2; I-Vrek sisikhawulezi esicetyiswayo somoya, m / s (sithathwe ilingana ne-0.5-1 m / s kwiziteshi kunye ne-1-1.5 m yeemigodi).
- Icandelo eliqhelekileyo lomnqamlezo likhethiwe, kufutshane ne-F.
- Ububanzi obulinganayo be-DUCT D bugqityiwe.
- Sebenzisa iitafile ezikhethekileyo kunye ne-nomograms ye-L no-D, ukuncipha kwe-R, isantya V.
- Ngokweetafile ze-coefficients zokunganyangeki kwendawo, ukwehla kweoksijini kumiselwa ngenxa yezithixo zalapha ekhaya ze z.
- Ilahleko yonke kuzo zonke iindawo zimiselweyo.
Inqaku lesihloko: Indlela yokwenza i-eriyali yeTV ngezandla zakho
Ukuba ilahleko iyonke incinci kunengcinezelo yangoku, le nkqubo ye-ventilation inokuthathwa njengempumelelo. Ukuba ilahleko ingaphezulu, emva koko i-rattragm inokuthi ifakwe kwinkqubo yomoya, onokuyifumana ingcinezelo.
Ukuba inkqubo yokufihlakeleyo isebenza amagumbi aliqela apho kufuneka uxinzelelo olwahlukileyo, xa kubalwa, kuyafuneka ukuthathela ingqalelo ixabiso lecala okanye ukongezwa kwixabiso lelahleko eqhelekileyo.
Ukubala iAerodynamic yinkqubo eyimfuneko kuyilo lwenkqubo yokufihlakeleyo. Ibonisa ukusebenza kwamagumbi okudlula kwii-SITS ezichaziweyo. Kwaye umsebenzi ofanelekileyo wokwenza umoya ubonelela ngentuthuzelo yokuhlala kwakho.
