Kukhazikitsa dongosolo la HVAC la chipinda choyera kumaphatikizapo kuyesa kwa unit imodzi ndi kuyesa kulumikizana kwa dongosolo, ndipo kukhazikitsa kuyenera kukwaniritsa zofunikira za kapangidwe ka uinjiniya ndi mgwirizano pakati pa wogulitsa ndi wogula. Pachifukwa ichi, kukhazikitsa kuyenera kuchitika motsatira kwambiri miyezo yoyenera monga "Code for Construction and Quality Acceptance of Clean Room" (GB 51110), "Code for Construction Quality Acceptance of Ventilation and Air-Conditioning Projects (G1B50213)" ndi zofunikira zomwe zavomerezedwa mu mgwirizano. Mu GB 51110, kukhazikitsa dongosolo la HVAC la chipinda choyera kuli ndi zinthu izi: "Kugwira ntchito ndi kulondola kwa zida ndi mita zomwe zimagwiritsidwa ntchito pokhazikitsa dongosolo kuyenera kukwaniritsa zofunikira zoyeserera, ndipo kuyenera kukhala mkati mwa nthawi yovomerezeka ya satifiketi yowunikira." "Kugwiritsa ntchito njira yoyesera yolumikizirana ya HVAC yoyera chipinda. Asanayambe kugwira ntchito, zinthu zomwe ziyenera kukwaniritsidwa ndi izi: zida zosiyanasiyana mu dongosolo ziyenera kuyesedwa payekhapayekha ndikupambana mayeso ovomereza; makina ozizira (otentha) ofunikira pakuziziritsa ndi kutentha ayamba kugwira ntchito ndipo ayamba kugwira ntchito ndipo apambana mayeso ovomereza: Kukongoletsa chipinda choyera ndi mapaipi ndi mawaya a chipinda choyera (malo) kwatha ndipo kwapambana mayeso aumwini: chipinda choyera (malo) chatsukidwa ndikupukutidwa, ndipo kulowa kwa ogwira ntchito ndi zipangizo kwachitika motsatira njira zoyera; makina a HVAC oyera chipinda chatsukidwa mokwanira, ndipo mayeso opitilira maola 24 achitika kuti pakhale ntchito yokhazikika; fyuluta ya hepa yayikidwa ndipo yapambana mayeso otayikira.
1. Nthawi yoyambira ntchito yoyeserera kulumikizana kokhazikika kwa makina oyeretsera a HVAC okhala ndi gwero lozizira (lotentha) siyenera kupitirira maola 8, ndipo iyenera kuchitika pansi pa mkhalidwe wogwirira ntchito "wopanda kanthu". GB 50243 ili ndi zofunikira izi poyesa chipangizo chimodzi: ma ventilator ndi mafani m'mayunitsi oyendetsera mpweya. Njira yozungulira injini iyenera kukhala yolondola, ntchitoyo iyenera kukhala yokhazikika, sipayenera kukhala kugwedezeka kosazolowereka ndi phokoso, ndipo mphamvu yogwirira ntchito ya injini iyenera kukwaniritsa zofunikira za zikalata zaukadaulo wa chipangizocho. Pambuyo pa maola awiri ogwirira ntchito mosalekeza pa liwiro loyesedwa, kutentha kwakukulu kwa chipolopolo choyenda sikuyenera kupitirira 70°, ndipo kwa chogwirira chozungulira sikuyenera kupitirira 80°. Njira yozungulira injini ya pampu iyenera kukhala yolondola, sipayenera kukhala kugwedezeka kosazolowereka ndi phokoso, sipayenera kukhala kusinthasintha m'zigawo zolumikizira zomangiriridwa, ndipo mphamvu yogwirira ntchito ya injini iyenera kukwaniritsa zofunikira za zikalata zaukadaulo wa chipangizocho. Pambuyo poti pampu yamadzi yakhala ikugwira ntchito mosalekeza kwa masiku 21, kutentha kwakukulu kwa chipolopolo chotsetsereka cha bearing sikuyenera kupitirira 70° ndipo bearing yozungulira sikuyenera kupitirira 75°. Kuyesa kwa fan ya nsanja yozizira ndi kayendedwe ka madzi ozizira sikuyenera kupitirira maola awiri, ndipo ntchitoyo iyenera kukhala yanthawi zonse. Thupi la nsanja yozizira liyenera kukhala lokhazikika komanso lopanda kugwedezeka kwachilendo. Kuyesa kwa fan ya nsanja yozizira kuyeneranso kutsatira miyezo yoyenera.
2. Kuwonjezera pa mfundo zoyenera za zikalata zaukadaulo wa zida ndi muyezo wadziko lonse wa "Zida Zosungiramo Zinthu, Kukhazikitsa Zipangizo Zolekanitsa Mpweya ndi Zovomerezeka" (GB50274), ntchito yoyesera ya chipangizo choziziritsira iyeneranso kukwaniritsa mfundo izi: chipangizocho chiyenera kuyenda bwino, Sipayenera kukhala kugwedezeka kosazolowereka ndi phokoso: sipayenera kukhala kusinthasintha, kutuluka kwa mpweya, kutuluka kwa mafuta, ndi zina zotero mu zolumikizira ndi zotsekera. Kupanikizika ndi kutentha kwa kuyamwa ndi kutulutsa utsi kuyenera kukhala mkati mwa ntchito yanthawi zonse. Zochita za chipangizo chowongolera mphamvu, zolumikizira zosiyanasiyana zoteteza ndi zida zotetezera ziyenera kukhala zolondola, zomvera komanso zodalirika. Ntchito yanthawi zonse siyenera kukhala yochepera maola 8.
3. Pambuyo pa ntchito yoyeserera yogwirizana ndi kukhazikitsa makina a HVAC a chipinda choyera, magwiridwe antchito osiyanasiyana ndi magawo aukadaulo ayenera kukwaniritsa miyezo ndi zofunikira za mgwirizano. Pali malamulo otsatirawa mu GB 51110: Kuchuluka kwa mpweya kuyenera kukhala mkati mwa 5% ya kuchuluka kwa mpweya wopangidwa, ndipo kusiyana kwa muyezo kuyenera kukhala kopitirira 15%. Osapitirira 15%. Zotsatira za mayeso a kuchuluka kwa mpweya woperekedwa m'chipinda choyera chosakhala chautali umodzi ziyenera kukhala mkati mwa 5% ya kuchuluka kwa mpweya wopangidwa, ndipo kusiyana kwa muyezo (kusagwirizana) kwa kuchuluka kwa mpweya wa tuyere iliyonse sikuyenera kukhala kopitirira 15%. Zotsatira za mayeso a kuchuluka kwa mpweya watsopano siziyenera kukhala zochepera mtengo wa kapangidwe, ndipo siziyenera kupitirira 10% ya mtengo wa kapangidwe.
4. Zotsatira zenizeni za muyeso wa kutentha ndi chinyezi m'chipinda choyera (malo) ziyenera kukwaniritsa zofunikira pa kapangidwe; mtengo wapakati wa muyeso weniweni umachokera ku mfundo zowunikira zomwe zatchulidwa, ndipo mtengo wopatuka uyenera kukhala woposa 90% ya mfundo zoyezera mkati mwa mulingo wolondola womwe umafunikira pa kapangidwe. Zotsatira za mayeso a kusiyana kwa kuthamanga kwa mpweya pakati pa chipinda choyera (malo) ndi zipinda zapafupi ndi kunja ziyenera kukwaniritsa zofunikira pa kapangidwe, ndipo nthawi zambiri ziyenera kukhala zazikulu kuposa kapena zofanana ndi 5Pa.
5. Mayeso a kayendedwe ka mpweya m'chipinda choyera ayenera kuwonetsetsa kuti mitundu ya kayendedwe ka mpweya - kuyenda kolunjika mbali imodzi, kuyenda kosagwirizana mbali imodzi, malo olumikizirana matope, ndi kuyenera kukwaniritsa zofunikira pa kapangidwe ndi zofunikira zaukadaulo zomwe zavomerezedwa mu mgwirizano. Pa zipinda zoyera kayendedwe ka mpweya kolunjika mbali imodzi ndi kayendedwe kosakanikirana, kapangidwe ka mpweya kayenera kuyesedwa pogwiritsa ntchito njira yotsatirira kapena njira yotsatirira, ndipo zotsatira zake ziyenera kukwaniritsa zofunikira pa kapangidwe. Mu GB 50243, pali malamulo otsatirawa okhudza ntchito yoyesa kulumikizana: kuchuluka kwa mpweya wosinthasintha Pamene makina oziziritsira mpweya agwiritsidwa ntchito limodzi, chipangizo choyendetsera mpweya chiyenera kukwaniritsa kusintha kwa mafupipafupi ndi kuwongolera liwiro la fan mkati mwa magawo a kapangidwe. Chipangizo choyendetsera mpweya chiyenera kukwaniritsa zofunikira za kuchuluka kwa mpweya wonse wa dongosolo pansi pa kapangidwe ka mphamvu yotsalira kunja kwa makina, ndipo kusiyana kololedwa kwa kuchuluka kwa mpweya watsopano kuyenera kukhala 0 mpaka 10%. Zotsatira zazikulu za kusintha kwa kuchuluka kwa mpweya wa chipangizo chosinthira kuchuluka kwa mpweya ndi kusiyana kololedwa kwa kuchuluka kwa mpweya wa kapangidwe ziyenera kukhala . ~ 15%. Mukasintha momwe zinthu zilili kapena momwe kutentha kwa mkati kumakhalira m'nyumba mwa dera lililonse loziziritsira mpweya, ntchito (ntchito) ya netiweki ya mphepo (fani) ya chipangizo chosinthira mpweya m'deralo iyenera kukhala yolondola. Mukasintha momwe kutentha kwa mkati kumakhalira kapena kutseka zipangizo zina zoziziritsira mpweya m'chipinda, chipangizo chogwiritsira ntchito mpweya chiyenera kusintha voliyumu ya mpweya yokha komanso molondola. Magawo a momwe zinthu zilili m'dongosololi ayenera kuwonetsedwa bwino. Kusiyana pakati pa kayendedwe ka madzi ozizira (otentha) ndi makina ozizira komanso kayendedwe ka kapangidwe kake sikuyenera kupitirira 10%.
