Wajibaha Hawya iyo Awoodda HVAC Vent Diffuser

Sida Wajibaha Hawya (CFM) Ugu Sareeyso Awoodda HVAC Vent Diffuser

Helitaanka xaddiga saxda ah ee hawada ayaa muhiim u ah sida wanaagsan ee qalabka hawada ee HVAC uu u shaqeeyo si uu dadka ugu dhigo kuwo raaxo leh isla markaana uu yahay mid wax ku ool ah. Tirada ayaa sidoo kale muhiim ah maadaama nidaamyada guryaha ay caadi ahaan ka shaqeeyaan 800 ilaa 1,200 oo fuudh oo cubic daqiiqaddii. Taasi waxay ka dhigan tahay in rakibayaashu ay u baahan yihiin inay doortaan qalabka kala-goynta leh furitaanno waaweyn iyo xawaaraha hawada oo gaabis ah si hawada qaboojiyaha ay si siman u kala firdho iyadoon la samayn buuqyo dhibaya. Marka ay diffusers-ku aad u yar yihiin, waxay ka dhigaan iska caabin dheeraad ah nidaamka gudahiisa. Tani waxay ka dhigeysaa wax walba inay ka sii adagtahay waxayna dhab ahaantii kor u qaadi kartaa biilasha tamarta qiyaastii 15%, sida laga soo xigtay cilmi baarista REMARS ee sanadkii hore. Dhinaca kale, in aad wax badan u kordhiso sidoo kale ma fiicna. Qaybiyaha ballaaran ee hawada ayaa u oggolaanaya hawada inay si tartiib tartiib ah ugu dhex socoto, taas oo keenta heerkulka aan simanayn ee meel kasta iyo meelaha kulul / qabow oo dhibaatooyin la dareemi karo u noqonaya dadka deggan.

Isku-darka cabirka diffuser-ka iyo xawaaraha baxitaanka awoodda nidaamka

Xaqiiqsanaanka saamaynta diffuser iyo awoodda sistema HVAC ayaa noqon doona muhiim tahay sababtoo ah wuu xidhi kara in lagu dhex marayo fans iyo compressors si joogsan. Tusaale ahaan, qaybta gaaban ee caadiga ah oo 48 inch ilaa 12 inch. Kuwaasu mararka qaarkood waxay u fogaan karaan 1800 cubic feet per minute (cfm) sidaas darteed haddii hawga ka soo baxaysan ka yar ta 400 feet per minute. Marka laga duwan yahay, waxaan helnay "air dumping". Waa markii hawgii ku dhajiya ama ku xooreya lama guuldo inuu gaadhado meelaha in aan la kulmo dadka. Qodobka? Qaar ka mid ah meelaha way gurkaraan, laakiinna qaar kale way socdaan, taasoo abuura in ay kala jirto xaaladaha sare iyo hoose, waxayna abuura in aan la kulmin ama in ay soo kooriso mashakeliinta magaalooyinka.

Xisaabinta Fogaanta Saamaynta si loo gaaro Aqoonsiga Xaaladda Kala Duwan

Dhererka saafidda waa mahad sareeya markii hawada soo bixsaday ugu yaraayo ilaa 50 qiyam marqood (feet per minute), taas oo muujiya in macalinta hawada (diffuser) ay dhammaan kicis la'aanta loo baahan yahay. Tusaale ahaan, guri kulan ku tiirsan 15 ilaa 20 qiyam marqood (feet). Sidaas darteed in lagu helo saafid wanaagsan, in ka badan injiinierada isku dayaan in saafidda uu gaadhdo 12 ilaa 14 qiyam marqood. Siiyaaddan waxaa lagu gaadhi karaa macalinta jajab ah 8 duyun (inch) oo kororsaday 600 qiyam kagac (cubic feet) marqood (per minute). Marka lagu dhisaa arrimaha kan, waayahan-qaab-dhismeedka waxaa loo isticmaalaa xisaab farsamada ah sida Saafid wajib tahay 0.75 la wadaray jidka labaad ee CFM oo la wadaray daacadka. Xisaabtan waxay caawiyaan in la helo xagga wanaagsan ee loo hubiyo in dhammaan dadka ay heli doonaan hawada wanaagsan, halkaas oo kale in la ka bilaabo goobaha qurux badan ama meelaha aan si toos ah u diririn karin.

Sarrafaasha Habeenka Hawada iyo Ujeedinta Xagga Si Wanaagsan

Diffuser-ka maalintan ayaa ka soo saara in la xidho dhaadheerka hawada adoo isticmaalaya louvers ku badan iyo noocyada guduudka ah oo keliya inay caawiyaan in la macaamilo hawada si sax. Tusaale ahaan, diffuser-ka radiaaraha ku jira dhulka wuxuu bixiyaa hawada dhammaan dhexdooda 360 digrii, taas oo fideysanaysa meelaha weyn sida diwaankii hotel-ka. Diffuser-ka qaylka mar kale wuxuu bixiyaa hawada garbar-garbareed, wanaagsan meelaha toosan sida koridorka halkaas oo meeshiisu yahda mid aad u gaaban. Ijidda xoogga leh ee horumarsan kula dhexeeya noocan waxa uu si fiican u kala jar daacadaha barako ah 40% marka loo eexdo mudoolka cudurka ah ee blade-ka dhow. Oo ninka aan rabnin inuu galo guri oo walax walba isku daynayo inuu tahay biyaha iyo tokafka kale tahay sayn. Dhaadhiska waa muhiim, diffuser-kan cusubna waxa uu siinayaa kan.
