UNGADZORA SEI KUDZORA KUSIYANA KWEMHEPO YEKUDZORA MUMUKATI WAKANAKA?

Kudzora huwandu hwemhepo inomanikidzwa zvakasiyana-siyana kwakakosha kuti imba icheneswe uye kudzivirira kupararira kwehutachiona. Aya ndiwo matanho akajeka uye nzira dzekudzora huwandu hwemhepo kuti ikwanise kusiyanisa kumanikidzwa.

1. Chinangwa chikuru chekudzora vhoriyamu yemhepo inodzvanywa

Chinangwa chikuru chekudzora huwandu hwemhepo inoshanduka-shanduka ndechekuchengetedza musiyano wesimba pakati peimba yakachena nenzvimbo yakapoteredza kuitira kuve nechokwadi chekuchena kweimba yakachena uye kudzivirira kupararira kwezvinosvibisa.

2. Nzira yekudzora vhoriyamu yemhepo inosiyana-siyana

(1). Sarudza zvinodiwa pakusiyana kwekumanikidzwa

Zvichienderana nezvinodiwa pakugadzira uye zvinodiwa pakugadzira imba yakachena, sarudza kana musiyano wekumanikidzwa pakati peimba yakachena nenzvimbo yakapoteredza uchifanira kuva wakanaka kana kuti usina kunaka. Musiyano wekumanikidzwa pakati pemakamuri akachena emhando dzakasiyana uye pakati penzvimbo dzakachena nenzvimbo dzisina kuchena haufanirwe kunge uri pasi pe5Pa, uye musiyano wekumanikidzwa pakati penzvimbo yakachena nekunze haufanirwe kunge uri pasi pe10Pa.

(2). Verenga musiyano wemhepo inomanikidzwa

Huwandu hwemhepo inobuda inogona kuverengerwa nekufungidzira huwandu hwenguva dzekuchinja kwemhepo mukamuri kana nzira yemugodhi. Nzira yemugodhi ine musoro uye yakarurama, uye inotarisa kusimba kwemhepo nenzvimbo yemugodhi yechivakwa chakavharirwa.

Fomura yekuverenga: LC = µP × AP × ΔP × ρ kana LC = α × q × l, apo LC iri vhoriyamu yemhepo inodiwa kuti imba yakachena irambe iine musiyano wemhepo, µP ndiyo flow coefficient, AP inzvimbo yemukana, ΔP ndiyo musiyano wemhepo isingachinji, ρ ndiyo density yemhepo, α ndiyo safety factor, q ndiyo vhoriyamu yemhepo inobuda pahurefu hwemukana, uye l ndiyo kureba kwemukana.

Nzira yekudzora yakagamuchirwa:

① Nzira yekudzora vhoriyamu yemhepo inogara iripo (CAV): Kutanga sarudza nguva inoshandiswa ne air conditioner system kuti uve nechokwadi chekuti vhoriyamu yemhepo inopihwa inoenderana nehuwandu hwemhepo hwakagadzirwa. Sarudza chiyero chemhepo itsva wochigadzirisa kuti chienderane nehukuru hwedhizaini. Gadzirisa kona ye damper yemhepo inodzoserwa ye corridor yakachena kuti uve nechokwadi chekuti musiyano we pressure ye corridor uri mukati mehuwandu hwakakodzera, iyo inoshandiswa sechiratidzo chekugadzirisa musiyano we pressure yemamwe makamuri.

② Nzira yekudzora vhoriyamu yemhepo inoshanduka (VAV): Gara uchigadzirisa vhoriyamu yemhepo inobuda kana vhoriyamu yemhepo inobuda kuburikidza nedamper yemagetsi yemhepo kuti uchengetedze kumanikidzwa kwaunoda. Nzira yekudzora pressure yemhando ye "pure differential pressure" (OP) inoshandisa sensor yekudzora pressure yakasiyana-siyana kuyera musiyano wepressure pakati penzvimbo nenzvimbo yekutarisa, uye inoienzanisa nenzvimbo yakatarwa, uye inodzora vhoriyamu yemhepo inobuda kana vhoriyamu yemhepo inobuda kuburikidza nePID adjustment algorithm.

Kugadziriswa uye kugadziriswa kwesystem:

Mushure mekunge sisitimu yaiswa, kuisirwa kwemhepo inoyerera kunoitwa kuti ive nechokwadi chekuti huwandu hwemhepo inomanikidzwa hwakasiyana hunosangana nezvinodiwa zvekugadzira. Gara uchitarisa uye uchichengetedza sisitimu, kusanganisira mafirita, mafeni, madhimbi emhepo, nezvimwewo, kuti uve nechokwadi chekuti sisitimu inoshanda zvakanaka.

3. Pfupiso

Kudzora huwandu hwemhepo inomanikidzwa zvakasiyana-siyana chinhu chakakosha mukugadzirwa kwemakamuri akachena uye manejimendi. Nekuona kudiwa kwemusiyano wekumanikidzwa, kuverenga huwandu hwemhepo inomanikidzwa, kushandisa nzira dzakakodzera dzekudzora, uye kuisa nekuchengetedza sisitimu, kuchena nekuchengetedzeka kwekamuri rakachena kunogona kuve nechokwadi uye kupararira kwezvinosvibisa kunogona kudzivirirwa.
