I-Chiller, Cooling Tower kanye ne-Air Handling Unit isebenza kanjani ndawonye ukuze ihlinzeke ngesiphephetha-moya (HVAC) esakhiweni.Kulesi sihloko sizobe sihlanganisa lesi sihloko ukuze siqonde izisekelo ze-HVAC central plant.

Umbhoshongo wokupholisa obandayo kanye ne-AHU kusebenza kanjani ndawonye

Izingxenye zesistimu eziyinhloko zesitshalo sokupholisa esimaphakathi yilezi:

• Chiller
• Iyunithi Yokuphatha Umoya (AHU)
• Ukupholisa Tower
• Amaphampu

I-chiller ngokuvamile izotholakala endaweni engaphansi noma ophahleni futhi lokhu kuncike ekutheni hlobo luni lwe-chiller olusetshenziswayo.Izibandisi eziphezulu eziphahleni zivame ukuthi “zipholile emoyeni” kuyilapho izindawo zokupholisa ezingaphansi ngokuvamile zithi “Amanzi apholisiwe” kodwa zombili zenza umsebenzi ofanayo wokuphehla amanzi abandayo esipholisa umoya ngokususa ukushisa okungafuneki esakhiweni.Umehluko kuphela ukuthi i-chiller ikulahla kanjani ukushisa okungafuneki.

Ama-chiller apholile azosebenzisa amafeni ukuphefumula umoya opholile we-ambient phezu kwe-condenser yawo ukuze asuse ukushisa kusistimu, lolu hlobo alusebenzisi umbhoshongo wokupholisa.Ungafunda ngalolu hlelo futhi ubuke isifundo sevidiyo ngokuchofoza lapha.Esikhathini esisele salesi sihloko sizogxila emanzini apholise ama-chillers nemibhoshongo yokupholisa.

I-chiller epholile yamanzi inamasilinda amabili amakhulu, eyodwa ibizwa ngokuthi i-evaporator kanti enye ibizwa ngokuthi i-condenser.

Amanzi abandayo:
I-evaporator ye-chiller yilapho "amanzi abandayo" akhiqizwa khona.“Amanzi abandayo” ashiya i-evaporator cishe ku-6°C (42.8°F) futhi adudulwe ebhilidini ngephampu yamanzi epholile.Amanzi abandayo ageleza akhuphuke ngobude besakhiwo aye esitezi ngasinye ngamapayipi aziwa ngokuthi “izikhuphukeli”.Lawa mapayipi aziwa ngokuthi ama- riser noma amanzi ageleza phezulu noma phansi phakathi kwawo.

Amanzi abandayo asuka ezikhuphukeni abe amapayipi amancane aqonde kumayunithi wekhoyili yabalandeli (ama-FCU) kanye namaYunithi Okuphatha Umoya (AHU's) ukuze anikeze isiphephetha-moya.Ama-AHU kanye nama-FCU's amabhokisi anabalandeli ngaphakathi abamunca umoya ovela esakhiweni futhi bawuphushele kumakhoyili okushisa noma okupholisa ukuze ushintshe izinga lokushisa lomoya bese uphusha lo moya ubuyele esakhiweni.Amanzi abandayo angena ku-AHU/FCU bese edlula kukhoyili yokupholisa (uchungechunge lwamapayipi amancane) lapho ezomunca ukushisa komoya ovunguza ngaphesheya.Amanzi abandayo ayashisa futhi nomoya ovunguza kuwo uphole.Lapho amanzi abandayo eshiya ikhoyili yokupholisa azobe esefudumala cishe ku-12°C (53.6°F).Amanzi afudumele abandile abe esephindela emuva ku-evaporator, ngesikhuphukeli esibuyayo, futhi uma esengene ku-evaporator isiqandisi sizomunca ukushisa okungafuneki futhi sikudlulisele ku-condenser.Amanzi abandayo azophinde ashiye epholile, elungele ukuzungeza isakhiwo futhi aqoqe ukushisa okungafuneki okwengeziwe.Qaphela: amanzi abandayo abizwa ngokuthi "amanzi abandayo" kungakhathaliseki ukuthi afudumele noma apholile.

Amanzi e-Condenser:
I-condenser ye-chiller yilapho ukushisa okungafuneki kuqoqwa khona ngaphambi kokuthunyelwa emibhoshongweni yokupholisa.Isiqandisi sidlula phakathi kwe-evaporator kanye ne-condenser ukuhambisa konke ukushisa okungafuneki.Enye iluphu yamanzi, eyaziwa ngokuthi "amanzi e-condenser", idlula ku-loop phakathi kwe-condenser nombhoshongo wokupholisa.Isiqandisi siqoqa ukushisa kusuka ku-loop "yamanzi abandayo" ku-evaporator futhi sikuhambisa lokhu ku-loop "yamanzi e-condenser" ku-condenser.

Amanzi e-condenser angena ku-condenser cishe ku-27°C (80.6°F) futhi azodlula, aqoqe ukushisa endleleni.Ngesikhathi isuka ku-condenser izoba cishe ku-32°C (89.6°F).Amanzi e-condenser nesiqandisi awahlangani, ahlala ehlukaniswa udonga lwamapayipi, ukushisa kudlulisa nje odongeni.Uma amanzi e-condenser esedlule ku-condenser futhi athatha ukushisa okungafuneki, azokhuphukela emibhoshongweni yokupholisa ukuze alahle lokhu kushisa futhi abuyisele indawo epholile elungele ukuqoqa ukushisa okwengeziwe.

Umbhoshongo wokupholisa:
Umbhoshongo wokupholisa ngokuvamile utholakala phezulu ophahleni futhi uyindawo yokugcina yokushisa okungadingeki esakhiweni.Umbhoshongo wokupholisa uqukethe isiphephetha-moya esikhulu esiphephezela umoya ngeyunithi.Amanzi e-condenser ampontshelwa phezulu emibhoshongweni yokupholisa futhi afuthwe emoyeni.Umoya opholile we-ambient uzongena futhi uthintane ngqo nesifutho samanzi e-condenser (embhoshongweni wokupholisa ovulekile) lokhu kuzovumela ukushisa kwamanzi e-condenser ukuthi kudlulele emoyeni bese lo moya uphume uphumele emkhathini.Amanzi e-condenser abe eseqoqa futhi aphindele emuva ku-condenser yokupholisa elungele ukuqoqa ukushisa okwengeziwe.Bheka isifundo sethu esikhethekile semibhoshongo yokupholisa lapha.
