Chiller, Cooling Tower uye Air Handling Unit inoshanda sei pamwe chete kuti ipe air conditioning (HVAC) kuchivakwa.Muchinyorwa chino tichave tichivhara nyaya iyi kuti tinzwisise izvo zveHVAC yepakati chirimwa.

Iyo chiller inotonhorera tower uye AHU inoshanda pamwe chete

Iwo makuru masisitimu eiyo central kutonhora chirimwa ndeaya:

• Chiller
• Air Handling Unit (AHU)
• Cooling Tower
• Mapombi

Iyo chiller inowanzove iri mukamuri yepasi kana padenga uye izvi zvinoenderana nerudzi rwechiller runoshandiswa.Denga repamusoro rinotonhora rinowanzo "Air cooled" nepo pasi pepasi chillers kazhinji "Mvura yakatonhodzwa" asi ese anoita basa rimwe chete rekuburitsa mvura inotonhora yekufefetera nekubvisa kupisa kusingadiwe kubva muchivako.Musiyano chete ndewekuti chiller inorasa sei kupisa kusingadiwe.

Air cooled chillers achashandisa mafeni kuridza inotonhorera ambient mhepo pamusoro pecondenser yavo kubvisa kupisa kubva muhurongwa, iyi mhando haishandise shongwe yekutonhodza.Iwe unogona kudzidza nezve system iyi uye tarisa vhidhiyo tutori nekudzvanya pano.Kune kwasara kwechinyorwa chino tichatarisa pamvura yakatonhodzwa chiller uye shongwe dzekutonhodza.

Mvura inotonhorera inotonhorera ine macylinders makuru maviri, imwe inonzi evaporator uye imwe inonzi condenser.

Mvura inotonhorera:
Iyo evaporator yechiller ndipo panogadzirwa "mvura inotonhorera"."Mvura inotonhora" inosiya evaporator pane 6°C (42.8°F) uye inosairirwa kutenderedza chivako nepombi yemvura inotonhora.Mvura inotonhora inoyerera ichikwira kumusoro kwechivako ichienda kune imwe neimwe pasi mumapombi anozivikanwa se "riser".Mapombi aya anozivikanwa nekusimuka zvisinei kuti mvura irikuyerera ichikwira kana pasi mukati mawo.

Mapazi emvura yakatonhorwa kubva pazvikwiriso kuita mapaipi madiki dhayamita anonanga kumafan coil units (FCU's) uye Air Handling Units (AHU's) kuti ape mhepo yekufefetera.Iyo AHU neFCU's mabhokisi ane mafeni mukati anoyamwa mweya mukati kubva muchivako uye anoisundira painodziya kana kutonhora macoil kuti achinje tembiricha yemhepo uye wosundira mweya uyu uchidzokera kunze muchivako.Mvura yakatonhorwa inopinda muAHU/FCU uye inopfuura nepainotonhodza coil (nhevedzano yepombi dzakatetepa) iyo inotora kupisa kwemhepo inovhuvhuta.Mvura inotonhora inopisa uye mhepo inovhuvhuta pamusoro payo inotonhora.Kana mvura yakatonhorwa ichisiya koiri inotonhodza inenge yava kudziya inenge 12°C (53.6°F).Mvura inodziya yakatonhora inobva yadzokera kune evaporator, kuburikidza nemukwidza wekudzokera, uye kana yangopinda muevaporator firiji inotora kupisa kusingadiwi uye yoendesa izvi kune condenser.Mvura inotonhora inobva yasiya inotonhorera zvakare, yakagadzirira kutenderera muchivako uye kuunganidza kumwe kupisa kusingadiwi.Cherechedza: mvura inotonhora inonzi "mvura inotonhorera" pasinei nokuti inodziya kana kuti inotonhorera.

Condenser mvura:
Iyo condenser yechiller ndiyo iyo kupisa kusingadiwi kunounganidzwa kusati kwatumirwa kunotonhora shongwe.Firiji inopfuura pakati peevaporator necondenser kufambisa kupisa kusingadiwi.Imwe chiuno chemvura, inozivikanwa se "condenser mvura", inopfuura muchiuno pakati pe condenser uye shongwe inotonhorera.Iyo firiji inounganidza kupisa kubva mu "mvura inotonhora" muvharo mu evaporator uye inofambisa izvi kune "condenser water" loop mu condenser.

Mvura inogadzirisa inopinda mucondenser inenge 27 ° C (80.6 ° F) uye ichapfuura, ichiunganidza kupisa munzira.Painozobva mucondenser inenge yasvika 32°C (89.6°F).Iyo condenser mvura uye refrigerant haitombosanganiswa, inogara yakaparadzaniswa nemadziro epombi, kupisa kunongotamisa nemumadziro.Kana mvura yecondenser yapfuura nemucondenser uye yatora kupisa kusingadiwe, inokwira kumusoro kunotonhora shongwe kuti irase kupisa uku uye kudzorera inotonhorera yakagadzirira kuunganidza kumwe kupisa.

Cooling tower:
Iyo inotonhodza shongwe inowanzoiswa pamusoro pedenga uye ndiyo yekupedzisira nzvimbo yekupisa kusingadiwi muchivako.Iyo yekutonhodza tower ine hombe feni inofuridza mweya kuburikidza neyuniti.Mvura yecondenser inopombwa kusvika kushongwe dzekutonhodza uye inopfapfaidzwa mumhepo.Mhepo inotonhorera inotonhorera ichapinda uye inosangana yakananga nekupfapfaidza kwemvura yecondenser (munzvimbo yakashama yekutonhodza) izvi zvinotendera kupisa kwemvura yekonduri kuti iende mumhepo uye mweya uyu wobva wapeperetswa mumhepo.Mvura yecondenser inobva yaunganidza uye yodzokera kune inotonhorera condenser yakagadzirira kuunganidza kumwe kupisa.Tarisa uone yedu yakakosha tutorial pane inotonhorera shongwe pano.
