Dareereha kulaylka wareegga wareegga -Ubucda soo kabashada kulaylka ee AHU
Mabda'a Shaqada
Wareejinta kulaylka wareegga dareeraha ah waa dareere ku beddela kulaylka hawada, kulaylka beddelayaasha ayaa inta badan lagu rakibaa dhinaca hawada cusub (OA) iyo hawada qiiqa (EA), bamka u dhexeeya labada kulayl. beddelayaashu waxay sameeyaan dareeraha wareega, ka dibna kulaylka dareeraha ah ayaa horay u sii kululeynaya ama horay u qaboojiya hawada cusub. Caadi ahaan dareeruhu waa biyo, laakiin jiilaalka, si loo yareeyo barta qaboojinta. ethylene glycol dhexdhexaad ah ayaa lagu dari doonaa biyaha boqolkiiba macquul ah.
Tilmaamaha Holtop Dareereha kulaylka wareegga wareegga
(1) Hawo nadiif ah iyo kulaylka hawada qiiqa ee ay isweydaarsadaan tubooyinka dareeraha ah ee kala go'an, wasakhaynta eber. Waxay ku habboon tahay badbaadinta tamarta ka soo kabashada kulaylka ee habka hawo-mareenka ee isbitaalka, shaybaarka aan jeermiska lahayn iyo warshadaha sii daaya sun iyo gaas waxyeello leh.
(2) Deggan, la isku hallayn karo oo adeeg dheer
(3) Xidhiidh dabacsanaan leh oo ka dhexeeya hawo cusub iyo sariflayaasha hawada qiiqa, rakibid fudud, kaas oo sidoo kale ku habboon hagaajinta AHU hore.
(4) Sarriflayaasha kulaylku waa kharashyada dayactirka caadiga ah, fudud oo hooseeya.
(5) Codsiga ballaaran, hababka isku xirka kala duwan sida mid ka mid ah, mid ka badan, ama qaar badan oo badan.
Tilmaamaha
(1) Beddelayaasha kulaylka wareegga dareeraha waa kulaylka macquulka ah, hufnaantu waxay u dhaxaysaa 55% ilaa 60%.
(2) Nambarada safafka la soo jeediyay ee 6 ama 8, xawaaraha weji aan ka badnayn 2.8 m/s
(3) Doorashada bamka wareegeysa waxay tixraaci kartaa hawo cusub iyo qiiqa cadaadiska hawada iyo hoos u dhaca cadaadiska biyaha.
(4) Jihada socodka hawadu waxay saameyn weyn ku leedahay hufnaanta soo kabashada kulaylka, heerka saamaynta ilaa 20%.
(5) Bar qaboojinta ee ethylene glycol iyo biyuhu waa inay ka hooseeyaan 4-6 ℃ heerkulka ugu yar ee deegaanka ee jiilaalka, boqolkiiba isku-dhafka loo tixraaco shaxdan soo socota.
