Mugumisiro wacho: mhepo inofefetera uye kumanikidzwa zvine mwero pamwe nekudzoreredza simba uye kushanda kwayo kunosimbiswa.
5) Misungo yekudzivirira—uye maitiro ekugadzirisa
Kunhuwa kwemvura kubva muzvimbuzi kuenda kumahofisi kunowanzo konzerwa nekubuda kwemhepo isina simba, kusafambisa mhepo yekuzora, kana kutadza kudzora kumanikidzwa kwemhepo. Mushonga wacho uri nyore: tarisai kubuda kwemhepo kubva pachinhu chimwe nechimwe, ipai nzira yakajeka yemhepo yekuzora kubva munzvimbo dzakachena, uye simbisai kumanikidzwa kusina kunaka nekuverenga kweutsi nePa panguva yeTAB uye mukushanda nguva dzose.
Kupfupisa mafambiro emagetsi mumakamuri emisangano kunoitika kana majeti emagetsi achidonhedzwa zvakananga mukudzoka kana kuti ma diffuser agere mumakona asina kumira. Gadzirisa ma terminals kuti akurudzire kusanganiswa munzvimbo yese yakatorwa, tarisa kukanda uye kupinza kwemagetsi pakufamba kwedhizaini yako, uye shandisa CFD panzvimbo dzakaoma kana nzvimbo dzemisangano dzine njodzi huru.
Kukwira kwekumanikidzwa kwemafirita hakuwanzo kuverengerwa pakusarudzwa kwemafeni. Ipa mukana weDP yekupedzisira, trend nemasensor, uye stage filtration kuti uwedzere nguva. Kana mafeni akafamba nenzira yakakombama pakutanga, unenge uchitevera matambudziko ehupenyu hwese hwesystem.
MaERV anotonhora anogona kutonhora kana nzira dzekunyungudutsa kana kupwanya dzisina kugadziriswa. Simbisa kudzora kumhanya kwevhiri kana kuti preheat/bypass sequences, uye edza pasi pemamiriro ezvinhu akaedzwa. Wedzera maalamu ekutadza kuitira kuti bypass yakanamirwa isagare kwenguva yakati rebei.
Kupedzisa: Matanho ako anotevera
Sarudza nzira yako yekutevedzera mitemo (ASHRAE 62.1 VRP kana EN 16798 Nzira 1), nyora nhamba dzenzvimbo yako chaiyo, uye nyora pasi hwaro hwedhizaini.
Sarudza mhinduro yeERV/DOAS kana AHU ine mashandiro akasimbiswa uye kanenge MERV 13/ePM1 ≥50% yekusefa pasi; simbisa nzvimbo yefeni yeDP yekusefa.
Gadzirai ma ductwork, ma terminals, uye hukama hwekumanikidzwa kudzivirira kupfupika kwemhepo uye kufamba kwemunhuwi; rongai kuti mupinde uye mudzikise kunhuwa.
Komisheni kumitemo yeASHRAE 202 uye fambisa matanho akakosha.
Kana muchida rutsigiro rwakagadzirira kutsanangurwa kana mapakeji edata rezvigadzirwa zveERV/DOAS munzvimbo dzisina mahwindo, timu yedu yeinjiniya kuAirwoods inogona kubatsira kuenzanisa zvinangwa zvekugadzira nemidziyo ine zvitupa uye zvekudzora.
