Kutentha ndi chinyezi sensa kwa HVAC mpweya ducts kuti detector kutentha & chinyezi

HVAC ndi chidule cha Chingerezi cha Ventilation and Air Conditioning chomwe chimatenthetsa mpweya wabwino komanso zoziziritsa mpweya. Sizimangoyimira zomwe zili pamwambazi zamaphunziro ndi zaukadaulo komanso zimayimira malonda okhudzana ndi mafakitale omwe akukhudzidwa ndi nkhaniyi ndiukadaulo. HVAC imatanthawuzanso mutu wofunsira womwe umakhudza kwambiri kamangidwe ka dziko lonse lapansi, mapulojekiti ndi makampani opanga zinthu. Pali HVAC Association, HVAC nthambi ya zomangamanga ku China (oimira bungwe la China) m'dziko lililonse. Chiphunzitso cha kutentha kwa kutentha, engineering thermodynamics ndi hydromechanics ndi ziphunzitso zawo zoyambirira. Mayendedwe awo ofufuza ndi chitukuko akuwonetsa malo ogwirira ntchito komanso ophunzirira bwino kwa anthu.

Lingaliro la chikhalidwe cha mpweya kuti lipereke kuzirala, kutentha, kapena kuchepetsa chinyezi ndilofanana. Kugwiritsa ntchito refrigerant pansi pa zochita za kompresa, evaporation kapena condensation, potero kuchititsa evaporation kapena condensation wa ozungulira mpweya, kukwaniritsa cholinga kusintha kutentha ndi chinyezi. Ndizofunikira kudziwa kuti "makina otenthetsera" ndi osowa ndipo kutentha kwamafuta kumakhala kwakukulu kuposa zida zabwino kwambiri za 1 (Ngati "greenhouse effect" siyikuganiziridwa. Izi zimapangitsa kuti zisagwiritsidwe ntchito m'malo otentha kuposa momwe zimakhalira.

HVAC ndi mpweya wokhala ndi kutentha, mpweya wabwino komanso mpweya wabwino.
HAVC ndiye chidule chambiri cha ntchito zake zazikulu zitatu -Kutentha, Ventilating ndi Air Conditioning.

HVAC ndi njira yoyendetsera mpweya kapena zida zofananira zomwe zimayang'anira kutentha ndi mpweya wabwino m'nyumba ndi mgalimoto. Mapangidwe a dongosolo la HVAC akukhudzana ndi thermodynamics, hydromechanics ndi makina amadzimadzi, omwe ndi gawo lofunikira lanthambi ya Mechanical engineering field. Nthawi zina, "R" amawonjezeredwa mu HVAC yomwe imayimira Refrigeration. Kotero kuti chidulecho chikusandulika "HVAC&R" kapena "HVACR".Kapena kuwonjezera mu "R" ndikuchotsa "V" yomwe imayimira mpweya wabwino, chidulecho chimakhala "HACR". Dongosolo la HVAC limatha kuwongolera kutentha kwa mpweya ndi chinyezi, kuwongolera chitonthozo chamkati. Ndi njira yofunikira ya nyumba zapakati ndi zazikulu zamafakitale kapena nyumba zamaofesi (monga skyscraper).

Muzomangamanga zamakono, ntchito yomwe ili pamwambayi (kuphatikiza machitidwe ake olamulira ndi mapangidwe & kukhazikitsa dongosolo) idzaphatikizidwa mu machitidwe amodzi a HVAC. Panyumba yaying'ono, kontrakitala amasankha makina a HVAC ndi zida monga zofunikira zawo mwachindunji. Kwa wamkulu, kusankha kwadongosolo la HVAC kudzawunikidwa ndikupangidwa ndi opanga zomangamanga ndi mainjiniya a makina ndi kapangidwe, ndikuyikidwa ndi katswiri wamakina.

Dongosolo la HVAC ndi bizinesi yapadziko lonse lapansi yomwe imaphatikizapo magwiridwe antchito, kukonza, kapangidwe & kapangidwe kake, opanga zida & bizinesi, kuphunzira & kukwezera maphunziro. Makampani a HVAC adayendetsedwa ndi opanga zida za HVAC m'mbuyomu. Pali zambiri zoyang'anira mayiko ndi mabungwe omwe amakhudzidwa ndi derali. Kuphatikiza HARDI, ASHRAE, SMACNA, Air Conditioning Contractors of America, Uniform Mechanical Code ndi International Building Code amagwiritsidwa ntchito popereka mautumiki okhudzana ndi HVAC ndikuwongolera mlingo wake.
