Kuti kuve nechokwadi chekuti tembiricha yemhepo yemukati, hunyoro, kumhanya, uye kuchena zvinogutsa zvinodiwa pakushanda uye kunyaradzwa kwevashandi, hurongwa hwemhepo hunofanirwa kugadzirwa nenzira ine musoro kuitira kuti kufamba kwemhepo munzvimbo iyi kuenderane nezvinodiwa mukamuri rekuchenesa.
Kurongeka kwemhepo inoyerera mukamuri rekushambidzika kwakasiyana zvikuru nemhepo inotonhodza yakajairika. Basa guru remhepo inoyerera mukamuri rekushambidzika nderekupa mweya wakachena wakakwana kuti uderedze nekutsiva tsvina inobuda mumba, uchichengetedza kuchena mukati memiganhu inobvumirwa. Kusiyana neizvi, makamuri ane mhepo inotonhodza kazhinji anoshandisa nzira dzemhepo dzinoyerera dzakasimba, achishandisa mhepo shoma kuti tembiricha nehunyoro zvienzane. Ipai mhepo inosanganiswa zvakanaka nemhepo yemukamuri kuti pave netembiricha yakaenzana uye kumhanya kwakafanana. Nekuda kweizvozvo, dhizaini yemhepo inoyerera mukamuri rekushambidzika inofanira kutevedzera zvinotevera zvakakosha.
Zvinhu Zvakakosha Pakugadzira Mhepo Inofamba Nedivi Rimwe Chete
1. Dzivisa Kubuda Kwesefa
Kana mafirita akadonha, mukana mukuru wemhepo inoyerera nenzira imwe chete unokanganiswa. Saka, kudonha kwemvura kunofanira kudzivirirwa.
2. Iva nechokwadi chekuti mhepo inoyerera zvakaenzana
Wedzera chiyero chekufukidza firita kuti uderedze kukanganiswa kwenzvimbo dzisina kusimba dzemafuremu.
3. Kuvandudza Kuenzana kweKufambisa Kwemhepo
Kumhanya kwesimba remagetsi kusina kufanana kunowanzo kukonzerwa nekumanikidzwa kusina kuenzana pakati pemafirita neplenum, pamwe nekumhanya kwakanyanya kwekupinda muplenum. Matanho makuru ekudzivirira anosanganisira:
(1) Sarudza mafirita anoshanda zvakanyanya. Panguva yekuisa, enzanisa mayuniti zvichienderana nekupikisa kwega kwega kuitira kuti kusiyana pakati pekupikisa kwefirita chero ripi zvaro neavhareji yeboka kuve pasi pe5%.
(2) Isa zvidimbu zvekupfapfaidza pasi pemafirita—kunyangwe zvidimbu zvekupfapfaidza zvisina kufanana kana zvichidikanwa. Wedzera kukwirira kweplenum, zviri nani kupfuura 800 mm.
(3) Chinja kubva pakugoverwa kwenzira dzemagetsi dziri pakati kuenda ku plenum kuenda kugoverwa kwenzira dzemagetsi dziri pakati nepakati.
(4) Kana kumhanya kwekupinda kwemhepo kwakanyanya kana kuti kungokwanisa kupinda kwedivi rimwe chete, isa ma baffle anogadziriswa pamafirita ari pedyo nekupinda kwemhepo. Neimwe nzira, wedzerai kuramba kwemukati me plenum nekuisa plate yakaboorwa pedyo nepanobuda mhepo.
4. Kuvandudza Kudzoka Kwemhepo Inomhanya Kufanana
Matanho akafanana anoshandiswa pakupa ducts anogona kushandiswa pakudzorera ducts: kugoverwa kweducts, kuyera dampers, kunyorovesa jira pa return grilles, kuderedza return face velocity iri pasi pe5 m/s, uye kugadzirisa floor opening ratios.
Zvinhu Zvakakosha Pakugadzira Mhepo Isingaenderane Nedivi Rimwe
1. Ramba Uchimanikidzwa Zvakanaka
(1) Kuyerera kwemhepo ine pressurization Kuyerera kwemhepo ine pressurization kunonyanya kutariswa nekubuda kwemhepo muhamvuropu. Kana ichiratidzwa sekuchinja kwemhepo paawa (ACH), mareferensi anoratidzwa pazasi. Kuti muwane fungidziro dzakaoma, shandisai 2–3 ACH.
| Kudzvinyirirwa Mukamuri (Pa) | Inodiwa ACH (Musuwo Wakaviri) | ACH Inodiwa (Musuwo Mumwe Chete) |
| 9.8 (1.0 mmH₂O) | 4.0 | 2.6 |
| 14.7 (1.5 mmH₂O) | 5.1 | 3.3 |
| 19.6 (2.0 mmH₂O) | 6.0 | 4.0 |
| 29.4 (3.0 mmH₂O) | 7.5 | 4.9 |
| 44.1 (4.5 mmH₂O) | 9.5 | 6.2 |
(2) Kudzora Kudzvanywa Kwemhepo Funga nezvesimba remaumbirwo emahamvuropu uye nyore kwekuvhura magonhi. Kazhinji, dzora musiyano wekudzvanywa kwemhepo nemakamuri ari pedyo ari pakati pe5–20 Pa (0.5–2.0 mmH₂O).
2. Dzora Kugadzira Guruva Remunharaunda
Mumakamuri asina kuchena anoshandiswa nenzira imwe chete, mhepo inoyerera zvine simba inobvumira guruva kupararira chero kupi. Kana guruva rinogadzirwa munharaunda rikakanganisa imba yese zvakaenzana, mhedzisiro yacho haidiwi; kunyangwe kuwedzera kukuru kwekuchinja kwemhepo kunounza kuvandudzika kushoma. Nzira yakanakisisa ndeyekugadzirisa kurongeka kwemhepo yemunharaunda zvakananga nekuisa michina inogadzira guruva yemunharaunda uye kupa utsi hwemunharaunda.
3. Sarudzo yeMusoro weKudzvanywa kweFan
Tsika yekare yekusarudza kumanikidzwa kwefeni ine margin yakawandisa haina kukodzera. Nekuti mafirita anoshanda pasi pemhepo yakayerwa mukushanda chaiko, kusarudza feni kaviri, kuramba kwefirita kunogadzira margin yekutanga yekumanikidzwa yakawandisa, zvichikonzera kuyerera kwemhepo yakawandisa uye kumhanya. Kuderedza ma dampers zvakanyanya kunobva kwagadzira ruzha rwakakosha. Kana kuramba kwesisitimu kuchigona kuverengerwa zvakadzama, kuramba kwekupedzisira kubva kumafirita akaomarara kusvika kune anoshanda zvakanyanya kunogona kutorwa sekudzivisa kwekutanga pamwe ne50–120 Pa. Kana kuramba kwesisitimu kwakaoma kuverenga kana kungoda kufungidzira kwakaoma, nzira yemazuva ano yekuramba kwekutanga kaviri inogona kushandiswa.
4. Kusarudzwa kwevateveri
Sarudza mafeni anoshanda zvakanyanya uye asingashandise ruzha rwakanyanya. Zvakakosha kuti nzvimbo yekushanda ive pachikamu chakatetepa chemugero wekushanda kwefeni, uye kuti mugero wacho pachawo uve wakadzika kwete kuti wati sandara. Izvi zvinoita kuti shanduko huru dzekumanikidzwa dziite kuti mhepo ishanduke zvishoma, zvichidzivirira kukanganisa kukuru kwekushanda.
Pfupiso
Muchidimbu, kurongeka kwemafambiro emhepo chinhu chakakosha chedhizaini yekamuri rekuchenesaMapurogiramu mazhinji anoda software yekufananidzira yeCFD yekuongorora kufamba kwemhepo, achishandisa mufananidzo wemhedzisiro yekufananidzira kuti asimbise dhizaini.
