Iyo mhepo inobata unit (AHU) ndiyo yakakura-chiyero, yakawanda tsika yekutengesa mhepo yekumisikidza iripo, uye kazhinji iri pamusoro pedenga remba kana madziro echivako. Uku kusanganiswa kwemidziyo yakati wandei yakavharwa muchimiro chebhokisi rakaita sebhokisi, rinoshandiswa kuchenesa, mhepo yekufemesa, kana kuzorodza mweya muchivako. Muchidimbu, mhepo inobata zvikamu zvinodzora (tembiricha & humidity) mamiriro ekupisa kwemhepo, pamwe nekuchena kwekusefa kwayo, uye vanozviita nekugovera mweya kuburikidza nemadhakisi anoenda kukamuri yega yega muchivakwa chako. Kusiyana neakajairika air conditioners, ahu hvac yakavakwa kuti ienderane nezvivakwa zvega, ichiwedzera mafirita emukati, humidifiers, uye zvimwe zviridzwa zvekudzora mwero wemhepo uye coziness mukati.

Mabasa makuru eAHU

Heating, Ventilation, uye Air Conditioning (Commerical Industrial HVAC) masisitimu ari pamwoyo weinjini dzemazuva ano, dzinofanirwa kuita dzichishandisa kufefetedza kwakakwana uye kunaka kwemhepo muzvivakwa zvikuru. Ahu muhvac inowanzoiswa padenga kana kunze kwemadziro uye inogovera mweya wakamisikidzwa kuburikidza nemadhakisi kumakamuri akasiyana. Aya masisitimu anogadzirirwa izvo zvinodikanwa zvechivako paanofanirwa kunge achitonhodza, kudziyisa, kana kufefetedza.

Hvac mhepo inobata zvikamu zvakakosha pakushambidzika kwemhepo uye CO2 nhanho kudzora munzvimbo dzepamusoro-traffic senge mashopu ezvitoro, theatre, uye horo dzemisangano. Ivo vanodhirowa mweya mutsva uye vanobatsira kudzikisa huwandu hwevanofuridza mafeni anodiwa - maviri-fer kuchengetedza pamitengo yesimba uye kusangana nemhando yemhepo zvinodiwa. Mamiriro ezvinhu akakosha, akadai sedzimba dzekuchenesa, dzimba dzemitambo, nezvimwewo zvinoda kwete kutonga tembiricha chete, asi hutsanana hwakakosha hunowanzo fambiswa kuburikidza neakazvitsaurira mweya mutsva wekubata zvikamu. Zvakare, kuputika-yemhepo inobata masisitimu anochengetedza kubva kune gasi kuputika kwezvivakwa zvinobata magasi anopisa.

Chii chinonzi AHU?

Ⅰ. Mhepo Intake: yakajairika mhepo inobata unit inotora kunze mhepo, kusefa, kugadzirisa, uye kuitenderedza muchivako kana kutenderedza mhepo yemukati kana zvakakodzera.

Ⅱ. Mafirita eMhepo: Aya anogona kunge ari mamecha mafirita anogona kubvisa zvakasiyana-siyana zvinosvibisa mhepo - huruva, mukume, uye kunyange mabhakitiriya. Mukicheni kana maworkshops, mafirita akasarudzika anogona kubatsira kubata njodzi dzakanangana, kusimudzira mweya wakachena uye kudzivirira kugadzirwa kwechinhu muhurongwa.

Ⅲ. Fani: Chikamu chinonyanya kukosha chehvac air handling unit iyo fan, iyo inoburitsa mweya muduti. Kusarudzwa kwefani nemhando inosanganisira kumberi-yakakomberedzwa, kumashure-yakakomberedzwa uye airfoil mafeni zvinoenderana neiyo static kumanikidza uye kuyerera kwemhepo zvinodiwa.

Ⅳ. Heat Exchanger: Iyo inopisa yekupisa inoshandiswa kubvumira kupindirana kwekupisa pakati pemhepo uye inotonhorera, uye kubatsira kuunza mweya kusvika kune inodiwa tembiricha.

Ⅴ. Kutonhodza Coil: Makoiri ekutonhodza anodonhedza tembiricha yemhepo inoyerera uchishandisa madonhwe emvura anounganidzwa mutireyi yecondensate.

Ⅵ. ERS: Iyo Energy Recovery System (ERS) inobatsirawo kuvandudza kushanda kwesimba nekufambisa simba rekupisa pakati pemhepo yakabviswa nemhepo yekunze, kuderedza kuwedzera kupisa kana kutonhora zvinodiwa.

Ⅶ. Heating Elements: Kupa imwezve tembiricha mutemo, kupisa zvikamu, zvinosanganisira maheta emagetsi kana kupisa kupisa, zvinogona kuiswa muAHU.

Ⅷ. Humidifier (s)/De-Humidifier(s): Izvi midziyo inogadzirisa hunyoro hwemhepo kuitira mamiriro akanaka emukati.

Ⅸ. The Mixing Section: Izvi zvinogadzira musanganiswa wakaenzana wemhepo yemukati nemhepo yekunze, kuitira kuti mhepo inotumirwa kuti igadzirwe ive patembiricha yakakodzera uye kunaka uku uchipedza simba shoma sezvinobvira.

Ⅹ. Causative: Silencers: Inoderedza ruzha kuti ichengetedze nharaunda ichinakidza sezvo Ruzha ruchigadzirwa panguva yekushanda kwevateveri uye zvimwe zvinhu.

Kushanda kwesimba kweAHUs

Kushanda kwesimba (kubvira 2016, chinodiwa pasi peEuropean Ecodesign Regulation 1235/2014) chinhu chakakosha cheiyo air handling unit (AHU). Inozviita nemayuniti ekudzoreredza kupisa anosanganisa mhepo yemukati nekunze, ichiunza musiyano wetembiricha padhuze, izvo zvinochengetedza simba rekugadzirisa mhepo. Iwo mafeni ane shanduko inodzora iyo inovapa kugona kuchinjika kune izvo zvinofema mhepo sezvinodiwa, zvichiita kuti iyo hvac mhepo inobata unit iite inoshanda uye yakazara kushoma simba rinoda.
