Inzwa yezinga lokushisa kanye nomswakamo yamapayipi okungenisa umoya e-HVAC kuya kudetector izinga lokushisa nomswakama

I-HVAC isifinyezo sesiNgisi se-Ventilation kanye ne-Air Conditioning efaka ukushisa komoya kanye ne-air conditioning. Ayimeli nje kuphela okuqukethwe okungenhla kwezemfundo nobuchwepheshe kodwa futhi imele ezohwebo nezimboni ezithintekayo kulesi sihloko nobuchwepheshe obungenhla. I-HVAC iphinde isho isihloko sohlelo lokusebenza esinomthelela omkhulu ekwakhiweni kwezakhiwo zomhlaba wonke, iphrojekthi kanye nemboni yokukhiqiza. Kukhona i-HVAC Association, igatsha le-HVAC lenhlangano yezokwakha yase-China(uhlaka olusemthethweni olumele i-China) ezweni ngalinye. Ithiyori yokudlulisa ukushisa, i-thermodynamics yobunjiniyela kanye ne-hydromechanics yimibono yabo eyisisekelo. Isiqondiso sabo socwaningo nentuthuko sifakazela indawo ekhululekile yokusebenza nokufunda yabantu.

Ithiyori yesimo somoya ukuze kuhlinzekwe ukupholisa, ukushisisa, noma ukususa umswakama uyafana. Ukusetshenziswa kwesiqandisi ngaphansi kwesenzo se-compressor, ukuhwamuka noma ukufingqa, ngaleyo ndlela kubangele ukuhwamuka noma ukufingqa komoya ozungezile, ukufeza inhloso yokuguqula izinga lokushisa nomswakama. Kuyaqapheleka ukuthi “umshini wokufudumala” awuvamile futhi ukusebenza kahle kokushisa kungaphezu kwemishini engu-1 encomekayo (Uma ungacatshangelwa “umphumela we-greenhouse.” Lokhu kwenza kungabi wusizo kakhulu ezindaweni ezishisayo kunalezo ezipholile.

I-HVAC iyisimo somoya esishisayo, i-ventilate kanye ne-air conditioning.
I-HAVC isifinyezo esibanzi semisebenzi yayo emithathu eyinhloko -Ukushisisa, I-Ventilating kanye ne-Air Conditioning.

I-HVAC iwuhlelo lokulawula umoya noma okokusebenza okuhlobene okuphethe ukushisisa nokufaka umoya ngaphakathi endlini nasemotweni. Idizayini yohlelo lwe-HVAC ihlobene ne-thermodynamics, i-hydromechanics nemishini ewuketshezi, okuyisihloko esibalulekile segatsha lenkambu yobunjiniyela beMechanical. Kwesinye isikhathi, u-“R” wengezwa ku-HVAC emele isiqandisi. Ukuze isifinyezo siguquke sibe “i-HVAC&R” noma “HVACR”.Noma singeza kokuthi “R” bese ususa u-“V” omele i-ventilate, isifinyezo siba “HACR”. Uhlelo lwe-HVAC lungalawula izinga lokushisa lomoya kanye nomswakama, luthuthukise ukunethezeka kwangaphakathi. Kuyinqubo ebalulekile yezakhiwo zezimboni eziphakathi nendawo nezinkulu noma izakhiwo zamahhovisi (njengesakhiwo esibhakabhakeni).

Ezakhiweni zesimanjemanje, umsebenzi ongenhla (okuhlanganisa nesistimu yawo yokulawula kanye nedizayini nokufakwa kwesistimu) izohlanganiswa ibe yisistimu eyodwa neziningi ze-HVAC. Ebhilidini elincane, usonkontileka uzokhetha uhlelo lwe-HVAC nezinto zokusebenza njengemfuneko yazo ngokuqondile. Kokukhulu, ukukhetha kohlelo lwe-HVAC kuzohlaziywa futhi kuklanywe abaklami bezakhiwo nonjiniyela bomshini nesakhiwo, futhi kufakwe usonkontileka ochwepheshe.

Uhlelo lwe-HVAC luyimboni yamazwe ngamazwe ehlanganisa uhlelo olusebenzayo, ukunakekela, ukuklama nokwakheka, umkhiqizi wezisetshenziswa nebhizinisi, ukufunda nokukhuthaza imfundo. Imboni ye-HVAC yayiphethwe umkhiqizi wemishini ye-HVAC ngaphambilini. Kuningi abaphathi bamazwe ngamazwe kanye nezinhlangano ezijwayelekile ezikhathazayo ngale ndawo. Kubandakanya i-HarDI, i-ASHRAE, i-SMACNA, I-Air Conditioning Contractors of America, I-Uniform Mechanical Code kanye ne-International Building Code zisetshenziselwa ukuhlinzeka ngezinsizakalo ezihlobene ne-HVAC futhi kuthuthukiswe izinga layo.
