Ukuqaliswa kwenkqubo ye-HVAC yegumbi elicocekileyo kuquka ukuqaliswa kovavanyo lweyunithi enye kunye nokuqaliswa kovavanyo lokudibanisa inkqubo, kwaye ukuqaliswa kufuneka kuhlangabezane neemfuno zoyilo lobunjineli kunye nesivumelwano phakathi komthengisi kunye nomthengi. Ngenxa yesi sizathu, ukuqaliswa kufuneka kwenziwe ngokuhambelana ngokungqongqo nemigangatho efanelekileyo efana ne "Code for Construction and Quality Acceptance of Clean Room" (GB 51110), "Code for Construction Quality Acceptance of Ventilation and Air-Conditioning Projects (G1B50213)" kunye neemfuno ezivunyelwene ngazo kwisivumelwano. Kwi-GB 51110, ukuqaliswa kwenkqubo ye-HVAC yegumbi elicocekileyo ikakhulu kunezi zibonelelo zilandelayo: "Ukusebenza kunye nokuchaneka kwezixhobo kunye neemitha ezisetyenziselwa ukuqaliswa kwenkqubo kufuneka kuhlangabezane neemfuno zovavanyo, kwaye kufuneka kube ngaphakathi kwexesha elifanelekileyo lesatifikethi sokulinganisa." "Ukusebenza okudibeneyo kwenkqubo ye-HVAC yegumbi elicocekileyo. Ngaphambi kokuba kuqaliswe ukusebenza, iimeko ekufuneka zifezekiswe zezi: izixhobo ezahlukeneyo kwinkqubo kufuneka zivavanywe ngokwahlukeneyo kwaye ziphumelele uvavanyo lokwamkelwa; iinkqubo ezifanelekileyo zomthombo obandayo (wobushushu) ezifunekayo ekupholiseni nasekufudumaleni zisebenze kwaye zigunyazisiwe kwaye ziphumelele uvavanyo lokwamkelwa: Ukuhombisa igumbi elicocekileyo kunye nemibhobho kunye neentambo zegumbi elicocekileyo (indawo) kugqityiwe kwaye kuphumelele uhlolo lomntu ngamnye: igumbi elicocekileyo (indawo) licociwe kwaye lisuliwe, kwaye ukungena kwabasebenzi kunye nezixhobo kwenziwe ngokweenkqubo ezicocekileyo; inkqubo ye-HVAC yegumbi elicocekileyo icociwe ngokupheleleyo, kwaye uvavanyo oluqhutywa iiyure ezingaphezu kwama-24 lwenziwe ukuze kufezekiswe ukusebenza okuzinzileyo; isihluzi se-hepa sifakiwe kwaye siphumelele uvavanyo lokuvuza.
1. Ixesha lokuqalisa ukusebenza kovavanyo lokudibanisa oluzinzileyo lwenkqubo ye-HVAC yegumbi elicocekileyo elinomthombo obandayo (ubushushu) akufuneki libe ngaphantsi kweeyure ezi-8, kwaye kufuneka lenziwe phantsi kwemeko yokusebenza "engenanto". I-GB 50243 ineemfuno ezilandelayo zovavanyo lweyunithi enye yezixhobo: ii-ventilators kunye neefeni kwiiyunithi zokuphatha umoya. Icala lokujikeleza kwe-impeller kufuneka libe lichanekileyo, ukusebenza kufuneka kuzinze, akufuneki kubekho ukungcangcazela okungaqhelekanga kunye nesandi, kwaye amandla okusebenza emoto kufuneka ahlangabezane neemfuno zamaxwebhu obuchwephesha bezixhobo. Emva kweeyure ezi-2 zokusebenza ngokuqhubekayo ngesantya esilinganisiweyo, ubushushu obuphezulu begobolondo lebhere elityibilikayo akufuneki lidlule kuma-70°, kwaye elo lebhere eliqengqelekayo akufuneki lidlule kuma-80°. Icala lokujikeleza kwe-impeller yepompo kufuneka libe lichanekileyo, akufuneki kubekho ukungcangcazela okungaqhelekanga kunye nesandi, akufuneki kubekho ukuyekelela kwiindawo zonxibelelwano ezibotshelelweyo, kwaye amandla okusebenza emoto kufuneka ahlangabezane neemfuno zamaxwebhu obuchwephesha bezixhobo. Emva kokuba ipompo yamanzi isebenza ngokuqhubekayo kangangeentsuku ezingama-21, ubushushu obuphezulu beqokobhe lebhereyi elityibilikayo akufuneki lidlule kuma-70° kwaye ibhereyi eqengqelekayo mayingadluli kuma-75°. Umsebenzi wovavanyo lokujikeleza kwefeni yenqaba yokupholisa kunye nenkqubo yamanzi okupholisa akufuneki ube ngaphantsi kweeyure ezi-2, kwaye umsebenzi kufuneka ube ngoqhelekileyo. Umzimba wenqaba yokupholisa kufuneka uzinze kwaye ungabi nokungcangcazela okungaqhelekanga. Ukusebenza kovavanyo lwefeni yenqaba yokupholisa kufuneka kuhambelane nemigangatho efanelekileyo.
2. Ukongeza kwimimiselo efanelekileyo yamaxwebhu obuchwephesha bezixhobo kunye nomgangatho wesizwe wangoku "Izixhobo zeFriji, Ulwakhiwo loBunjineli boKwahlula-hlula kweZixhobo zoMoya kunye neeNkcukacha zoKwamkela" (GB50274), ukusebenza kovavanyo lweyunithi yefriji kufuneka kuhlangabezane nemimiselo elandelayo: iyunithi kufuneka isebenze kakuhle, Akufuneki kubekho ukungcangcazela okungaqhelekanga kunye nesandi: akufuneki kubekho ukuyekelela, ukuvuza komoya, ukuvuza kweoyile, njl. kwiindawo zonxibelelwano kunye nokutywina. Uxinzelelo kunye nobushushu bokutsalwa kunye nokuphuma komoya kufuneka kube ngaphakathi koluhlu oluqhelekileyo lokusebenza. Izenzo zesixhobo esilawula amandla, iireyi ezahlukeneyo zokukhusela kunye nezixhobo zokhuseleko kufuneka zibe zichanekileyo, zinovelwano kwaye zithembeke. Ukusebenza okuqhelekileyo akufuneki kube ngaphantsi kweeyure ezi-8.
3. Emva kokusebenza ngokudibeneyo kunye nokuqaliswa kwenkqubo ye-HVAC yegumbi elicocekileyo, iiparameter ezahlukeneyo zokusebenza kunye nezobuchwephesha kufuneka zihlangabezane nemigangatho kunye neenkcukacha ezifanelekileyo kunye neemfuno zesivumelwano. Kukho le migaqo ilandelayo kwi-GB 51110: Umthamo womoya kufuneka ube ngaphakathi kwe-5% yomthamo womoya woyilo, kwaye ukuphambuka okuqhelekileyo akufanele kube ngaphezulu kwe-15%. Kungabi ngaphezu kwe-15%. Iziphumo zovavanyo lomthamo womoya wegumbi elicocekileyo lokuhamba elingekho kwicala elinye kufuneka zibe ngaphakathi kwe-5% yomthamo womoya woyilo, kwaye ukuphambuka okuqhelekileyo (ukungalingani) komthamo womoya we-tuyere nganye akufuneki kube ngaphezulu kwe-15%. Iziphumo zovavanyo lomthamo womoya omtsha mazingabi ngaphantsi kwexabiso loyilo, kwaye mazingabi ngaphezu kwe-10% yexabiso loyilo.
4. Iziphumo zokulinganisa zokwenyani zobushushu kunye nokufuma okunxulumeneyo kwigumbi elicocekileyo (indawo) kufuneka zihlangabezane neemfuno zoyilo; ixabiso eliqhelekileyo lokulinganisa lokwenyani livela ngokweendawo zokuhlola ezichaziweyo, kwaye ixabiso lokuphambuka kufuneka libe ngaphezulu kwe-90% yamanqaku okulinganisa ngaphakathi koluhlu lokuchaneka olufunekayo kuyilo. Iziphumo zovavanyo lomahluko woxinzelelo oluzinzileyo phakathi kwegumbi elicocekileyo (indawo) kunye namagumbi akufutshane kunye nangaphandle kufuneka zihlangabezane neemfuno zoyilo, kwaye ngokubanzi kufuneka zibe ngaphezulu okanye zilingane ne-5Pa.
5. Uvavanyo lwepateni yokuhamba komoya kwigumbi elicocekileyo kufuneka luqinisekise ukuba iintlobo zepateni yokuhamba - ukuhamba okuhamba ngendlela enye, ukuhamba okungahambanga ngendlela enye, ukudibana kodaka, kwaye kufuneka kuhlangatyezwane neemfuno zoyilo kunye neemfuno zobugcisa ezivunyelwene ngazo kwisivumelwano. Kwigumbi elicocekileyo ukuhamba okuhamba ngendlela enye kunye nokuhamba okuxutyiweyo, iphethini yokuhamba komoya kufuneka ivavanywe ngendlela yokulandelela okanye indlela yokufaka i-tracer, kwaye iziphumo kufuneka zihlangatyezwane neemfuno zoyilo. Kwi-GB 50243, kukho le migaqo ilandelayo yokusebenza kovavanyo lokudibanisa: ivolumu yomoya eguquguqukayo Xa inkqubo yomoya opholileyo iqaliswe ngokudibeneyo, iyunithi yokuphatha umoya kufuneka ifezekise ukuguqulwa kwamaza kunye nokulawulwa kwesantya kwefeni ngaphakathi koluhlu lweeparamitha zoyilo. Iyunithi yokuphatha umoya kufuneka ihlangatyezwane neemfuno zevolumu yomoya iyonke yenkqubo phantsi kwemeko yoyilo yoxinzelelo oluseleyo ngaphandle komatshini, kwaye ukuphambuka okuvumelekileyo kwevolumu yomoya omtsha kuya kuba yi-0 ukuya kwi-10%. Isiphumo esiphezulu sokulungisa ivolumu yomoya yesixhobo sesiphelo sevolumu yomoya eguquguqukayo kunye nokuphambuka okuvumelekileyo kwevolumu yomoya yoyilo kufuneka ibe yi-. ~15%. Xa kutshintshwa iimeko zokusebenza okanye iiparameter zokuseta ubushushu bangaphakathi kwindawo nganye yomoya opholileyo, isenzo (ukusebenza) kwenethiwekhi yomoya (ifeni) yesixhobo sesiphelo somoya esiguquguqukayo kwindawo leyo kufuneka sibe sesichanekileyo. Xa kutshintshwa iiparameter zokuseta ubushushu bangaphakathi okanye kuvalwa ezinye izixhobo zesiphelo somoya opholileyo kwigumbi, iyunithi yokuphatha umoya kufuneka itshintshe ngokuzenzekelayo nangokuchanekileyo ivolumu yomoya. Iiparameter zesimo senkqubo kufuneka ziboniswe ngokuchanekileyo. Ukuphambuka phakathi kokuhamba okupheleleyo kwenkqubo yamanzi abandayo (ashushu) omoya opholileyo kunye nenkqubo yamanzi okupholisa kunye nokuhamba koyilo akufuneki kudlule kwi-10%.
