KUDZORA SEI AKASIYANA KUDIRIRWA KWEMHEPO VOLUME MUMUMBA WAKACHENANA?

Differential pressure air volume control yakakosha kuti uve nechokwadi chekushambidzika kwekamuri yakachena uye kudzivirira kupararira kwekusvibiswa. Izvi zvinotevera matanho akajeka uye nzira dzekudzora mhepo yemhepo yekumanikidza kusiyana.

1. Chinangwa chikuru chekumanikidza kusiyanisa kudzora vhoriyamu yemhepo

Chinangwa chikuru chekumanikidza kusiyanisa mhepo yekudzora vhoriyamu kuchengetedza imwe static pressure musiyano pakati pekamuri yakachena nenzvimbo yakatenderedza kuve nechokwadi chekuchena kwekamuri yakachena uye kudzivirira kupararira kwezvinosvibisa.

2. Strategy for pressure differential air volume control

(1). Sarudza chinodiwa chekumanikidza musiyano

Zvinoenderana nemaitiro ekugadzira uye maitiro ekugadzira zvinodiwa zvekamuri yakachena, tarisa kana mutsauko wekumanikidza pakati pekamuri yakachena nenzvimbo yakatenderedza unofanirwa kuve wakanaka kana kuti usina kunaka. Musiyano wekumanikidza pakati pemakamuri akachena emagiredhi akasiyana uye pakati penzvimbo dzakachena nenzvimbo dzisina kuchena haifanire kunge iri pasi pe5Pa, uye mutsauko wekumanikidza pakati penzvimbo yakachena nekunze haufanire kunge uri pasi pe10Pa.

(2). Verenga musiyano wekumanikidzwa kwemhepo vhoriyamu

Huwandu hwemhepo yekudonha hunogona kuverengerwa nekufungidzira huwandu hwenguva dzekuchinja mhepo yemukamuri kana nzira yegeji. Iyo gap nzira inonzwisisika uye yakarurama, uye inofunga nezvemhepo yakasimba uye gap nzvimbo yeyakavharirwa chimiro.

Calculation formula: LC = µP × AP × ΔP × × kana LC = α × q × l, apo LC inotsikirira musiyano wemhepo inodiwa kuchengetedza kusiyana kwekukosha kwekamuri yakachena, µP ndiyo inoyerera coefficient, AP ndiyo gap nzvimbo, ΔP ndiyo static pressure factor, ρ ndiyo αqge ndiyo dhigirii yemhepo, iyo αq chiyero chemhepo yakachengetedzeka. yegap, uye ndini kureba kwegap.

Nzira yekudzora yakagamuchirwa:

① Constant air vhoriyamu yekudzora nzira (CAV): Chekutanga tarisa bhenji rekushandisa frequency yemhepo inofefetera system kuti uve nechokwadi chekuti mhepo yekugovera inoenderana neyakagadzirwa vhoriyamu yemhepo. Sarudza chiyero chemhepo yakachena uye chigadzirise kuti iite kukosha kwekugadzira. Rongedza kudzoka kwemhepo damper angle yemukoridho wakachena kuti uve nechokwadi chekuti corridor pressure mutsauko uri mukati memutsetse wakakodzera, uyo unoshandiswa sebhenji rekugadzirisa mutsauko wemamwe makamuri.

② Variable air vhoriyamu yekudzora nzira (VAV): Ramba uchigadzirisa mhepo yekugovera vhoriyamu kana kupera simba remhepo kuburikidza nemagetsi emhepo damper kuchengetedza yaunoda kudzvanywa. Iyo yakachena yekusiyanisa kudzvinyirira nzira yekudzora nzira (OP) inoshandisa yekusiyanisa kumanikidza sensor kuyera mutsauko wekumanikidza pakati pekamuri nenzvimbo yereferensi, uye inoienzanisa nenzvimbo yakatarwa, uye inodzora vhoriyamu yemhepo yekupa kana kupera simba kwemhepo kuburikidza nePID kugadzirisa algorithm.

System commissioning uye kugadzirisa:

Mushure mekuisirwa sisitimu, chiyero chemhepo chinomisikidzwa chinoitwa kuti ive nechokwadi chekuti kusiyanisa kudzvanywa kwemhepo vhoriyamu inosangana nezvinodiwa zvekugadzira. Gara uchitarisa uye chengetedza sisitimu, kusanganisira mafirita, mafeni, madhiraivha emhepo, nezvimwe, kuti ive nechokwadi chekugadzikana kwehurongwa hwekuita.

3. Pfupiso

Differential pressure air volume control ndiyo yakakosha link mukuchenesa kamuri dhizaini uye manejimendi. Nekuona mutsauko wemusiyano wekuda, kuverenga mutsauko wekumanikidzwa kwemhepo, kutora nzira dzakakodzera dzekudzora, uye kutumira nekuchengetedza sisitimu, kuchena uye kuchengetedzeka kwekamuri yakachena kunogona kuve nechokwadi uye kupararira kwezvinosvibisa kunogona kudzivirirwa.
