Kodi Chiller, Cooling Tower ndi Air Handling Unit imagwirira ntchito limodzi bwanji kuti apereke zoziziritsa kukhosi (HVAC) ku nyumba.M'nkhaniyi tikambirana nkhaniyi kuti timvetse zoyambira za HVAC chapakati chomera.

Momwe chiller yozizira nsanja ndi AHU zimagwirira ntchito limodzi

Zigawo zazikulu za makina oziziritsira chapakati ndi awa:

• Chiller
• Gawo la Air Handling Unit (AHU)
• Cooling Tower
• Mapampu

Chiller nthawi zambiri amakhala pansi kapena padenga ndipo izi zimatengera mtundu wanji wa chiller womwe umagwiritsidwa ntchito.Zozizira pamwamba padenga nthawi zambiri zimakhala "zozizira mpweya" pomwe zozizira zapansi nthawi zambiri zimakhala "Madzi oziziritsidwa" koma onse amagwira ntchito yofanana yomwe ndikupanga madzi ozizira oziziritsa mpweya pochotsa kutentha kosafunikira mnyumbamo.Kusiyana kokha ndi momwe chiller amataya kutentha kosafunikira.

Mpweya wozizira wozizira udzagwiritsa ntchito mafani kuwomba mpweya woziziritsa wozungulira pa condenser yawo kuti achotse kutentha padongosolo, mtundu uwu sugwiritsa ntchito nsanja yozizirira.Mukhoza kuphunzira za dongosolo lino ndi kuona kanema phunziro mwa kuwonekera apa.Kwa otsala a nkhaniyi tiona madzi utakhazikika chillers ndi kuzirala nsanja.

Madzi ozizira ozizira amakhala ndi masilinda awiri akulu, imodzi imatchedwa evaporator ndipo inayo imatchedwa condenser.

Madzi ozizira:
Evaporator ya chiller ndi pamene "madzi ozizira" amapangidwira."Madzi ozizira" amachoka mu evaporator pafupifupi 6°C (42.8°F) ndipo amakankhidwa mozungulira nyumbayo ndi mpope wamadzi wozizira.Madzi ozizira amayenda kutalika kwa nyumbayo mpaka pansi pa mipope yotchedwa " risers ".Mapaipiwa amadziwika kuti okwera ngakhale madzi akuyenda mmwamba kapena pansi mkati mwake.

Madzi ozizira amatha kuchoka pazikwenjezo kukhala mapaipi ang'onoang'ono omwe amapita ku ma fan coil units (FCU's) ndi Air Handling Units (AHU's) kuti azipereka zoziziritsa kukhosi.Ma AHU's ndi FCU's kwenikweni ndi mabokosi okhala ndi mafani mkati mwake omwe amayamwa mpweya kuchokera mnyumba ndikukankhira paziwotcha kapena zoziziritsa kuti zisinthe kutentha kwa mpweya ndikukankhira mpweya uwu kulowa mnyumbamo.Madzi ozizira amalowa mu AHU/FCU ndikudutsa pa koyilo yoziziritsa (mipope yopyapyala) komwe imayamwa kutentha kwa mpweya womwe ukuwomba.Madzi ozizira amatenthedwa ndipo mpweya wodutsa pamwamba pake umazizira.Madzi ozizira akachoka pa koyilo yozizirirayo amakhala akutentha pafupifupi 12°C (53.6°F).Madzi ozizira ozizira amabwereranso ku evaporator, kudzera mu chokwera chobwerera, ndipo akangolowa mu evaporator mufiriji amayamwa kutentha kosafunikira ndikusunthira izi kupita ku condenser.Madzi ozizirawo amachokanso ozizira, okonzeka kuzungulira nyumbayo ndikusonkhanitsa kutentha kosafunikira.Zindikirani: madzi ozizira amatchulidwa kuti "madzi ozizira" mosasamala kanthu kuti ndi otentha kapena ozizira.

Madzi a Condenser:
Condenser ya chiller ndi pamene kutentha kosafunikira kumasonkhanitsidwa musanatumizidwe ku nsanja zozizirira.Firiji imadutsa pakati pa evaporator ndi condenser kusuntha kutentha kosafunikira.Mtsinje wina wamadzi, wotchedwa "madzi a condenser", amadutsa mumtsinje pakati pa condenser ndi nsanja yozizira.Firiji imasonkhanitsa kutentha kuchokera ku "madzi ozizira" kuzungulira mu evaporator ndikusunthira izi ku "condenser water" loop mu condenser.

Madzi a condenser amalowa mu condenser pafupifupi 27 ° C (80.6 ° F) ndipo amadutsa, kusonkhanitsa kutentha panjira.Ikadzachoka pa condenser idzakhala pafupifupi 32°C (89.6°F).Madzi a condenser ndi firiji samasakanikirana, nthawi zonse amasiyanitsidwa ndi khoma la chitoliro, kutentha kumangodutsa pakhoma.Madzi a condenser akadutsa mu condenser ndikutenga kutentha kosafunikira, amapita ku nsanja zoziziritsa kuti atayire kutentha uku ndikubwezeretsa ozizira okonzeka kutengera kutentha kwina.

Cooling Tower:
Nsanja yozizira nthawi zambiri imakhala pamwamba pa denga ndipo ndi malo omaliza a kutentha kosafunikira mnyumbamo.Chinsanja chozizira chimakhala ndi fani yayikulu yomwe imawomba mpweya kudzera mu unit.Madzi a condenser amaponyedwa mpaka ku nsanja zozizirira ndipo amawapopera mumtsinje wa mpweya.Mpweya wozizira wozungulira udzalowa ndikukhudzana mwachindunji ndi kupopera kwa madzi a condenser (mu nsanja yozizirira yotseguka) izi zidzalola kutentha kwa madzi a condenser kupita mumlengalenga ndipo mpweya uwu umawululidwa mumlengalenga.Madzi a condenser ndiye amasonkhanitsa ndikubwerera ku condenser yozizira kukonzekera kutengera kutentha kwina.Onani phunziro lathu lapadera la nsanja zoziziritsa pano.
