Ukukhanya Phakathi Kwezinqamlezo Zokuzalisa Izulu Nezinqamlezo Zokuphatha Izulu

Okuchazwe Kakhulu Namasiko Amanye Kakhulu Kusistim ka-HVAC

Izinqamlezo Zokuzalisa Izulu Ziyiphi? Inhloso, Indlela Yokusetyenziswa, Ngegama Lomlando

Izinqamleli zokugunya kwenja, noma ARUs njengoba sizobizwa khona, zisebenza njengezinqamleli ezithile ze-HVAC ukuthatha inja endaweni ebalulekile apho izinqamleli ezinhle ngempela azifanele. Lezi zinqamleli zihlinza into iyaziwa ngokuthi ukwahluka kwesilinganiso secala - ingcinga engakwazanga kukhumbuzwa ngabantu abaningi kodwa ihlinza yonke indawo yokusebenzela ne-factory enenja eliphakeme. Inja ebuhlungu iphakama phezulu emuva kwesilinganiso, ngelapho inja ephelele isalembelela phansi emuva kwezidingo lesebenzi. I-ARUs ilungisa le nto ngokumaqhuba amava wokugunya okuphephile okumiswe ngokujulile okunikeza isimo esijulile. Isebenzisa lezi zinkawu ezinzulu zomgwa ezigxilwayo ukuthi zibambisane nezinye izigaba zenja. Ngokusho kwe-ASHRAE 2022, lezi zinqamleli zingasusa ukwahluka kwegesi ngaproximately amade 15 Fahrenheit ngaphandle kokudinga izixhumanisi ezintsha zokuphepha noma zokucindezela. Abasebenzi besendustri baze bathi ngokuthi 'destratification fans' noma 'air circulators' xa bahlala behlala. Kodwa ngaphakathi, i-ARUs iyasingakanani imali kumalini wezinja. Xa izilinganiso senja sibaluleka ngokujulile, izindleko zokuphepha ziphula kakhulu—ngokuvamile phakathi kwe-20% kuze kube ngu-30% kumathuba apho izilinganiso ziphakama ngaphezu kwezinja ezingu-20.

I-Air Handling Units (AHUs): Isakhiwo, Isilinganiso, kanye Nezidingo Ze-HVAC Integration

Izinto zokulayisha yamagetsi (AHUs) sebenza njengezinhlayiya ezikhuthaza le-HVAC ezenzo imisebenzi yehlathi ngemigomo engaphezu kweyodwa ngaphambi kokugcwaliswa. I-AHU ejwayelekile iyatholakala nge:

• Izinhlelo zokuhlenga , okwenzeka MERV 8–16 (noma HEPA emakhaya aphathekayo), ekususa izinto eziphazanyayo ezingaphezu kwe-0.3 microns
• Amashilafu okushisa/okulahla isithelo , usebenzisa amanzi noma irefrigerant ukulawula ubude be-temperature
• Amayishumi kanye ne-dehumidifiers , ekugcinwa kwe-40–60% ye-relative humidity ukuze kubekwe ubuhle bokuphila komuntu kanye nokulungiswa kwesiseko
• I-Energy recovery ventilators (ERVs) , ekunika futhi 60–80% we-thermal energy kusuka ku-air exhaust

Izinqamlezo zokuphatha amahuba zilala kusengaphakathini kwezinkundla ezimodiweyo ezigxilwe ngokuthuthana okutshintshayo, zixhumanisa kuwo wonke amadoti aphinde aphinde kuzo zonke izindawo ukuze aphinde amahubo avumelekileyo lapho kudingeka.
