HVAC ndiyo chidimbu cheChirungu cheVentilation uye Air Conditioning iyo iri kupisa kufefetedza uye mhepo yekufemesa.Haingomiriri zviri pamusoro pezvidzidzo uye zvehunyanzvi zvemukati asi zvakare inomiririra kutengeserana kwakabatana uye maindasitiri anobatanidzwa muchidzidzo chiri pamusoro uye tekinoroji.HVAC zvakare inoreva chidzidzo chekushandisa chine pesvedzero yakakura padhizaini yezvivakwa zvepasirese, chirongwa uye indasitiri yekugadzira.Kune HVAC Association, HVAC bazi rekuvaka nzanga yeChina (iyo yepamutemo mumiriri weChina) munyika imwe neimwe.Iyo dzidziso yekupisa kupisa, engineering thermodynamics uye hydromechanics ndiwo dzidziso dzavo dzakakosha.Kutsvagisa kwavo nekusimudzira gwara kuri kuratidza nzvimbo yakasununguka yekushanda uye yekudzidza yevanhu.
Dzidziso yemamiriro emhepo yekupa kutonhora, kupisa, kana dehumidification yakafanana.Kushandiswa kwefiriji pasi pechiito checompressor, evaporation kana condensation, nokudaro zvichikonzera kubuda kana kunyunguduka kwemhepo yakapoteredza, kuzadzisa chinangwa chekushandura kupisa uye humidity.Zvakakosha kuziva kuti "muchina wekudziya" hauwanzo uye kupisa kwekushisa kwakanyanya kudarika 1 yakanakisa midziyo (Kana iyo "greenhouse effect" isingatariswe. Izvi zvinoita kuti isanyanya kubatsira munzvimbo dzinopisa kupfuura idzo dzinodziya.
HVAC inzvimbo yemhepo ine kudziyisa, kufefetedza uye mhepo inofefetera.
HAVC ndiyo pfupiso yakazara yebasa rayo guru matatu -Heating, Ventilating uye Air Conditioning.
HVAC ndiyo dhizaini yekudzora mhepo kana midziyo yakabatana inotungamira kupisa uye kufefetera mukati uye mumotokari.Dhizaini yeHVAC system ine chekuita neiyo thermodynamics, hydromechanics uye fluid muchina, inova yakakosha bazi nyaya yeMechanical engineering munda.Dzimwe nguva, "R" inowedzerwa muHVAC inomiririra Refrigeration.Saka kuti chidimbu chiri kushanduka kuita “HVAC&R” kana “HVACR”.Kana kuwedzera mu“R” wodzima “V” inomirira mhepo inofefetera, chidimbu chinova “HACR”.Iyo HVAC sisitimu inogona kudzora tembiricha yemhepo uye hunyoro, ichivandudza kunyaradza kwemukati.Iyo yakakosha maitiro epakati uye makuru maindasitiri zvivakwa kana hofisi zvivakwa (senge skyscraper).
Mukuvaka kwazvino, basa riri pamusoro (kusanganisira yayo yekudzora sisitimu uye dhizaini & yekumisikidza sisitimu) ichabatanidzwa mune imwe uye yakawanda HVAC masisitimu.Kune chivakwa chidiki, mugadziri achasarudza iyo HVAC system nemidziyo sezvinodiwa zvavo zvakananga.Kune iyo hombe, sarudzo yeHVAC system ichaongororwa uye dhizaini nevagadziri vezvivakwa uye mainjiniya emuchina uye chimiro, uye inoiswa nenyanzvi yemuchina kondirakiti.
Iyo HVAC sisitimu iindasitiri yepasirese iyo inosanganisira iyo sisitimu inoshanda, kuchengetedza, dhizaini & chimiro, mugadziri wemidziyo & bhizinesi, kudzidza & kusimudzira dzidzo.Indasitiri yeHVAC yaitungamirwa nemugadziri wemidziyo yeHVAC kare.Kune akawanda manejimendi epasirese uye akajairwa masangano ane hanya nenzvimbo iyi.Kusanganisira HARDI, ASHRAE, SMACNA, Air Conditioning Contractors of America, Uniform Mechanical Code uye International Building Code inoshandiswa kupa mabasa ane chokuita neHVAC uye kuvandudza mwero wayo.
