I-HVAC sisishunqulelo sesiNgesi se-Ventilation kunye ne-Air Conditioning ekufudumeza i-ventilating kunye ne-air conditioning.Ayimelanga kuphela imixholo yezifundo nezobugcisa engasentla kodwa ikwamele urhwebo olunxulumeneyo kunye namashishini abandakanyekayo kwesi sifundo kunye nethekhinoloji engasentla.I-HVAC ikwathetha isifundo sesicelo esinefuthe elibanzi kuyilo lwezakhiwo zehlabathi, iprojekthi kunye neshishini lemveliso.Kukho i-HVAC Association, isebe le-HVAC lombutho wokwakha waseTshayina (iqumrhu elisemthethweni elimele iTshayina) kwilizwe ngalinye.Ithiyori yokudlulisa ubushushu, ubunjineli be-thermodynamics kunye ne-hydromechanics ziithiyori zabo ezisisiseko.Umkhombandlela wabo wophando kunye nophuhliso lungqina indawo yokusebenza nokufunda ekhululekileyo yabantu.
Ithiyori yemeko yomoya ukubonelela ukupholisa, ukufudumeza, okanye ukukhutshwa kwamanzi kuyafana.Ukusetyenziswa kwefriji phantsi kwesenzo se-compressor, i-evaporation okanye i-condensation, ngaloo ndlela ibangela ukuba i-evaporation okanye i-condensation yomoya ojikelezileyo, ufezekise injongo yokutshintsha ubushushu kunye nomswakama.Kuyaphawuleka ukuba "umatshini wokufudumala" unqabile kwaye ukusebenza kakuhle kwe-thermal kukhulu kune-1 yesixhobo esihle kakhulu (Ukuba "impembelelo ye-greenhouse" ayiqwalaselwa. Oku kwenza ukuba kungabi luncedo kakhulu kwiindawo eziphantsi kwe-tropical kunokuba zifudumele.
I-HVAC yimeko yomoya enezifudumezi, i-ventilate kunye ne-air conditioning.
I-HAVC sisishunqulelo esibanzi semisebenzi yayo emithathu engundoqo -Ukufudumeza, ukungenisa umoya kunye nokupholisa umoya.
I-HVAC yinkqubo yolawulo lomoya okanye izixhobo ezinxulumeneyo eziphethe ukufudumeza kunye nokungenisa umoya ngaphakathi kunye nasemotweni.Uyilo lwenkqubo ye-HVAC inxulumene ne-thermodynamics, i-hydromechanics kunye noomatshini bamanzi, into ebalulekileyo yesebe lecandelo lobunjineli boomatshini.Ngamanye amaxesha, "R" yongezwa kwi-HVAC emele isikhenkcisi.Ukuze isishunqulelo sijike sibe ngu "HVAC&R" okanye "HVACR".Okanye ukongeza kwi-"R" kwaye ucime i-"V" emele i-ventilate, isishunqulelo siba yi-"HACR".Inkqubo ye-HVAC inokulawula ubushushu bomoya kunye nokufuma, ukuphucula induduzo yangaphakathi.Yinkqubo ebalulekileyo yezakhiwo zoshishino eziphakathi kunye nezikhulu okanye izakhiwo zeofisi (ezifana ne-skyscraper).
Kulwakhiwo lwangoku, umsebenzi ongentla (kubandakanya inkqubo yawo yokulawula kunye noyilo kunye nokufakwa kwenkqubo) iya kudityaniswa kwiinkqubo ezininzi zeHVAC.Kwisakhiwo esincinci, unokontraka uya kukhetha inkqubo yeHVAC kunye nezixhobo njengemfuno yazo ngokuthe ngqo.Kowona mkhulu, ukhetho lwenkqubo yeHVAC luya kuhlalutywa kwaye luyilwe ngabayili bezakhiwo kunye neenjineli zoomatshini kunye nolwakhiwo, kwaye lufakwe ngunokontraka wobuchwephesha oomatshini.
Inkqubo ye-HVAC lushishino lwamazwe ngamazwe olubandakanya inkqubo yokusebenza, ukugcinwa, ukuyila kunye nolwakhiwo, umenzi wezixhobo & neshishini, ukufunda nokukhuthazwa kwemfundo.Ishishini le-HVAC lalilawulwa ngumenzi wezixhobo ze-HVAC ngaphambili.Kukho ulawulo lwamazwe ngamazwe kunye nemibutho esemgangathweni echaphazelekayo malunga nalo mmandla.Kubandakanya i-HARDI, i-ASHRAE, i-SMACNA, i-Air Conditioning Contractors yaseMelika, iKhowudi ye-Uniform Mechanical Code kunye ne-International Building Code isetyenziselwa ukubonelela ngeenkonzo ezinxulumene ne-HVAC kunye nokuphucula umgangatho wayo.
