Iyunithi yokuphatha umoya (AHU) ngowona mgangatho mkhulu, uninzi lwesiqhelo lomoya wokuthengisa umoya okhoyo, kwaye uhlala phezu kophahla okanye udonga lwesakhiwo. Olu ludibaniso lwezixhobo ezininzi ezivaliweyo ngokwemilo yebhloko emile okwebhokisi, esetyenziselwa ukucoca, ukungenisa umoya, okanye ukuhlaziya umoya kwisakhiwo. Ngamafutshane, iiyunithi zokuphatha umoya zilawula (iqondo lobushushu kunye nokufuma) imo yobushushu bomoya, kunye nokucoceka kokucoca kwayo, kwaye zikwenza oko ngokusasaza umoya ngemibhobho enabela kwigumbi ngalinye kwisakhiwo sakho. Ngokungafaniyo ne-air conditioners eqhelekileyo, i-ahu hvac yakhiwe ukuze ihambelane nezakhiwo zomntu ngamnye, yongeza izihluzi zangaphakathi, i-humidifiers, kunye nezinye izixhobo zokulawula umgangatho womoya kunye nokuzola ngaphakathi.

Imisebenzi ephambili ye-AHU

Iinkqubo zokufudumeza, ukuVela komoya, kunye nokuPholisa umoya (i-HVAC yezoRhwebo) zezona zisembindini weenjini zale mihla, ekufuneka zisebenze kusetyenziswa ukuphefumla ngeyona ndlela kunye nomgangatho womoya kwizakhiwo ezikhulu. I-Ahu kwi-hvac ngokuqhelekileyo ixhonywe eluphahleni okanye ngaphandle kwodonga kwaye isasaze umoya ococekileyo ngokusebenzisa imibhobho ukuya kumagumbi ahlukeneyo. Ezi nkqubo zenzelwe iimfuno ezithile zesakhiwo apho kufuneka ukuba zipholise, ukufudumeza, okanye ukukhupha umoya.

Iiyunithi zokuphatha umoya we-Hvac zibalulekile kucoceko lomoya kunye nolawulo lwenqanaba le-CO2 kwiindawo ezinetrafikhi ephezulu njengodederhu lweevenkile, iithiyetha kunye neeholo zenkomfa. Batsala umoya omtsha kwaye bancede ukunciphisa inani leefeni zokuvuthela ezifunekayo - i-ferre ezimbini ukugcina iindleko zamandla kunye nokuhlangabezana neemfuno zokuthotyelwa komgangatho womoya. Iimeko ezingqongileyo ezibalulekileyo, ezifana namagumbi okucoca, iithiyetha zokusebenza, njl.njl. azifuni kuphela ulawulo lobushushu, kodwa ucoceko olubalulekileyo olusoloko luququzelelwa ngeeyunithi zokuphatha umoya omtsha. Kwakhona, iisistim zokuphatha umoya ezingagqabhukiyo zikhusela kuqhushumbo lwerhasi kumaziko okuphatha iigesi ezinokutsha.

Iquka ntoni i-AHU?

Ⅰ. Ukungenwa komoya: Iyunithi yokuphatha umoya yesiqhelo ithatha umoya wangaphandle, ukuhluza, ukulungiswa, kunye nokuwujikeleza kwisakhiwo okanye ukujikeleza umoya wangaphakathi xa kufanelekile.

Ⅱ. Izihluzi zoMoya: Ezi zinokuba zizihluzi zoomatshini ezinokukhupha izingcolisi ezahlukeneyo zomoya-uthuli, umungu, kunye neebhaktheriya. Kwiikhikhini okanye kwiindibano zocweyo, izihluzi ezikhethekileyo zinokunceda ukulawula iingozi ezithile, ukukhuthaza umoya ococekileyo kunye nokuthintela ukwakhiwa kwezithako kwinkqubo.

Ⅲ. Umlandeli: Elona candelo libalulekileyo leyunithi yokuphatha umoya ye-hvac ifeni, ekhuphela umoya kumbhobho. Ukukhethwa kwefeni ngokohlobo kubandakanywa abalandeli be-front-curved, backward-curved kunye ne-airfoil ngokoxinzelelo lwe-static kunye neemfuno zokuhamba komoya.

Ⅳ. Isitshintshi sobushushu: Isitshintshi sobushushu sisetyenziselwa ukuvumela ukusebenzisana kwe-thermal phakathi komoya kunye nesipholisi, kwaye sincede ukuzisa umoya kubushushu obufunekayo.

Ⅴ. Ikhoyili yokupholisa: Iikhoyili zokupholisa ziwisa ubushushu bomoya ohamba phakathi kusetyenziswa amathontsi amanzi aqokelelwa kwitreyi yecondensate.

Ⅵ. I-ERS: I-Energy Recovery System (ERS) iphinda incede ukuphucula amandla ombane ngokuhambisa amandla ashushu phakathi komoya okhutshiweyo kunye nomoya wangaphandle, ukunciphisa ukufudumala okongeziweyo okanye imfuneko yokupholisa.

Ⅶ. Izinto zokufudumeza: Ukubonelela ngolawulo olongezelelweyo lobushushu, izixhobo zokufudumeza, kubandakanywa izifudumezi zombane okanye i-heat exchangers, zingabandakanywa kwi-AHU.

Ⅷ. IsiHumidifier (s)/De-Humidifier(s): Ezi zixhobo ezilawula ukufuma emoyeni kwiimeko ezifanelekileyo zangaphakathi.

Ⅸ. Icandelo lokuxuba: Oku kudala umxube olungelelanisiweyo womoya wangaphakathi kunye nomoya wangaphandle, ukwenzela ukuba umoya othunyelwe ukuba ulungelelaniswe kwiqondo lokushisa elifanelekileyo kunye nomgangatho ngelixa udla amandla amancinci ngokusemandleni.

Ⅹ. I-Causative: Izithulisi: Inciphisa ingxolo ukugcina indalo imnandi njengoko Ingxolo iveliswa ngexesha lokusebenza kweefeni kunye namanye amacandelo.

Ukusebenza kwamandla e-AHUs

Ukusebenza kwamandla (ukususela kwi-2016, imfuneko phantsi kwe-European Ecodesign Regulation 1235/2014) yinto ebalulekileyo yeyunithi yokuphatha umoya (AHU). Ikwenza oko ngeeyunithi zokubuyisela ubushushu ezixuba umoya wangaphakathi kunye nangaphandle, zisondeza umahluko wobushushu kunye, okonga amandla omoya opholileyo. Abalandeli banolawulo oluguquguqukayo olubanika amandla okumodareyitha kwiimfuno zokuhamba komoya njengoko kufuneka, okwenza ukuba iyunithi yokuphatha umoya ye-hvac isebenze ngakumbi kwaye ifune amandla amancinci ngokubanzi.
