Indlela iChiller, iCooling Tower kunye neAir Handling Unit ezisebenzisana ngayo

I-Chiller, i-Cooling Tower kunye ne-Air Handling Unit zisebenzisana njani ukubonelela nge-air conditioner (HVAC) kwisakhiwo. Kweli nqaku siza kuthetha ngalo mba ukuze siqonde iziseko ze-HVAC central plant.

Indlela inqaba yokupholisa i-chiller kunye ne-AHU ezisebenzisana ngayo

Izinto eziphambili zenkqubo yesityalo sokupholisa esiphakathi zezi:

• I-Chiller
• Iyunithi yoLawulo loMoya (AHU)
• Inqaba Yokupholisa
• Iimpompo

I-chiller idla ngokuba kwi-basement okanye eluphahleni kwaye oku kuxhomekeke kuhlobo lwe-chiller esetyenziswayo. Ii-chillers eziphezulu zophahla zihlala "zipholile emoyeni" ngelixa ii-chillers ze-basement zihlala "zipholile ngamanzi" kodwa zombini zenza umsebenzi ofanayo wokuvelisa amanzi abandayo okupholisa umoya ngokususa ubushushu obungafunekiyo kwisakhiwo. Umahluko kuphela yindlela i-chiller elahla ngayo ubushushu obungafunekiyo.

Ii-air cooled chillers ziza kusebenzisa iifeni ukuvuthela umoya opholileyo ojikeleze i-condenser yazo ukuze zisuse ubushushu kwinkqubo, olu hlobo alusebenzisi i-cooling tower. Ungafunda ngale nkqubo kwaye ubukele ividiyo yesifundo ngokucofa apha. Kwinxalenye eseleyo yeli nqaku siza kugxila kwii-cooler ezipholileyo ngamanzi kunye nee-cooling towers.

Isixhobo sokuphola esipholileyo ngamanzi sineesilinda ezimbini ezinkulu, enye ibizwa ngokuba yi-evaporator kwaye enye ibizwa ngokuba yi-condenser.

Amanzi abandayo:
I-evaporator ye-chiller kulapho kuveliswa khona "amanzi abandayo". "Amanzi abandayo" ashiya i-evaporator malunga ne-6°C (42.8°F) aze atyhalelwe kwisakhiwo yipompo yamanzi abandayo. Amanzi abandayo ahamba phezulu kwesakhiwo ukuya kumgangatho ngamnye kwimibhobho eyaziwa ngokuba yi-"risers". Le mibhobho yaziwa ngokuba yi-risers nokuba amanzi ahamba phezulu okanye ezantsi ngaphakathi kuyo.

Amanzi abandayo aphuma kwii-risers abe yimibhobho emincinci enobubanzi eya kwiiyunithi ze-fan coil (ii-FCU) kunye nee-Air Handling Units (ii-AHU) ukuze zinike umoya opholileyo. Ii-AHU kunye nee-FCU ngokuyintloko ziibhokisi ezineefeni ngaphakathi ezifunxa umoya ovela kwisakhiwo kwaye ziwutyhale kwiikhoyili zokufudumeza okanye zokuphola ukuze zitshintshe ubushushu bomoya uze emva koko utyhale lo moya ubuyele kwisakhiwo. Amanzi abandayo angena kwi-AHU/FCU aze adlule kwikhoyili yokuphola (uthotho lwemibhobho emincinci) apho aya kufunxa ubushushu bomoya obuvuthelayo. Amanzi abandayo ayashushu kwaye umoya ovuthelayo uyaphola. Xa amanzi abandayo eshiya ikhoyili yokuphola ngoku aya kuba shushu malunga ne-12°C (53.6°F). Amanzi afudumeleyo abandayo emva koko abuyela kwi-evaporator, nge-return riser, kwaye xa engena kwi-evaporator, i-refrigerant iya kufunxa ubushushu obungafunekiyo ize ibuhambise kwi-condenser. Amanzi abandayo aya kuphinda aphume epholile, elungele ukujikeleza isakhiwo aze aqokelele ubushushu obungafunekiyo. Qaphela: amanzi abandayo abizwa ngokuba “ngamanzi abandayo” nokuba ashushu okanye apholile.

Amanzi e-condenser:
I-condenser ye-chiller kulapho ubushushu obungafunekiyo buqokelelwa khona ngaphambi kokuba buthunyelwe kwiinqaba zokupholisa. I-refrigerant idlula phakathi kwe-evaporator kunye ne-condenser ukuze ihambise bonke ubushushu obungafunekiyo. Enye i-loop yamanzi, eyaziwa ngokuba yi-"condenser water", idlula kwi-loop phakathi kwe-condenser kunye ne-cooling tower. I-refrigerant iqokelela ubushushu kwi-"cooled water" loop kwi-evaporator ize ibuhambise kwi-"condenser water" loop kwi-condenser.

Amanzi e-condenser angena kwi-condenser malunga nama-27°C (80.6°F) aze adlule, eqokelela ubushushu endleleni. Xa iphuma kwi-condenser iya kuba malunga nama-32°C (89.6°F). Amanzi e-condenser kunye ne-refrigerant azidibani, zihlala zahlulwe ludonga lombhobho, ubushushu budlula nje eludongeni. Nje ukuba amanzi e-condenser adlule kwi-condenser aze athathe ubushushu obungafunekiyo, aya kunyuka aye kwiinqaba zokupholisa ukuze alahle obu bushushu aze abuyisele i-cooler ilungele ukuqokelela ubushushu obuninzi.

Inqaba yokupholisa:
Inqaba yokupholisa idla ngokuba phezulu eluphahleni kwaye yindawo yokugqibela apho ubushushu obungafunekiyo bufumaneka khona kwisakhiwo. Inqaba yokupholisa inefeni enkulu evuthela umoya ngaphakathi kweyunithi. Amanzi e-condenser ampontshwa aye kwiinqaba zokupholisa aze atshizwe kumlambo womoya. Umoya opholileyo ojikelezayo uya kungena kwaye udibane ngqo ne-spray yamanzi e-condenser (kwinqaba yokupholisa evulekileyo) oku kuya kuvumela ubushushu bamanzi e-condenser ukuba budlulele emoyeni kwaye lo moya emva koko uvuthelwe emoyeni. Amanzi e-condenser ayaqokelelana aze abuyele kwi-condenser ye-chillers elungele ukuqokelela ubushushu obuninzi. Jonga isifundo sethu esikhethekileyo malunga neenqaba zokupholisa apha.
