Shiga hpe tawn da u
Closed-loop cooling system hta, laksan hka n-gun lahkawng lawm ai: pat da ai kata na process n-gun n-gun hte shinggan de hka n-gun n-gun n-gun. Hka lang ai lam hte sum ai lam hpe circuit lahkawng gaw tsep kawp garan ginhka da ai.
Hka ra kadawn ai lam yawng gaw daw lahkawng hpe shinggrup da ai: hka n-gun hpe hkam la ai static system hte shani shagu bungli galaw na matu makeup hka. Htunghking hpaw da ai katsi ai nta ni hte shingdaw yu yang, hka-hpe laklai ai hku hkye la lu ai atsam hpe jaw ya nna, n-gun nnan, tsi hpaga lam, hkrak tup galaw shapraw ai hte data center ni a matu madung katsi ai hparan ladat hku nna magam gun nga ai.
I. Yawng Static Holding Hka N-gun (Kalang-Kalang Hpring Ai N-gun)
Static water volume ngu ai gaw, shawng nnan lang galaw hpang ai aten (sh) gram lajang ai lam kaba galaw ngut ai hpang, hka hpe tup hkrak shapraw kau ai shaloi, hka yawng hpe jahpring na hpe tsun mayu ai, dai hka gaw, kata na process hka hte shinggan na hka garan ai hka hte hpawng de da ai.
Sealed kata na ladat hka hkawm ai lam
Ndai circuit hpe coil, pipeline, heat exchanger hte buffer hka tank ni kata kaw nbung n shang hkra tup hkrak shinggrup da ai majaw, bungli galaw ai shaloi shingra hka hpe n law htum sum mat ai. Lahta na masat da ai ladat:Process Hka Hkrang=Pipeline Hkringmang + Coil Hkringmang + Buffer Tank Hkringmang Standard bungli galaw ai masa hta, static holding n-gun gaw 100 m3/h hta 8–12 m3 grup yin de du wa ai. m3/h npu lwi ai unit kaji ni gaw hka 3–6 m3 hpe hkam la lu ai.
N-gun hpe mahkawng da na matu hte 1,000 m3/h jan lwi ai chemical galaw ai lam ni a matu closed-loop system kaba ni hpe -kalang lang jahpring na matu cubic meter latsa daram du hkra ra ai. Hka n-gun ja ai, san seng ai hka (sh) ethylene glycol hka n-gun rawng ai hka hpe shinggrup ai lam hku nna lang ma ai. Shawng nnan hka bang ngut ai hpang hka pru wa na matu, hka htung kaji kajaw ni hpe sha jat bang ra ai, hka htung kaba- hpe shaning ting galai shai na matu n ra ai.
Shinggan de na hka garan ai hka
Spray hka gaw, n-gun rawng ai nbung hpe galai shai na matu, pat da ai coil ni a shinggan ntsa de lwi nna, nbung n-gun rawng ai nta a npu na hka sump hta bang da ai. Shi a static volume gaw, 20%–50% daram sha, n-gun rawng ai hka lim ai lam hpe hkam la lu ai. 500 m3/h hpaw da ai-loop process cooling system hpe ga shadawn hku nna la ga: hka lim ai hka lim ai lam gaw 100 kaw nna 250 m3/h du hkra rai nna, sump kata na static hka lim ai hka gaw 5–15 m3 sha rai nga ai, hka lim ai cubic metre latsa daram hta grau n law ai.
Hkum tsup ai hpaw da ai-loop system a yawng lang -kalang hpring ai n-gun gaw, bung ai nbung hpe shapraw kau lu ai atsam nga ai hpaw da ai system a 30%–50% sha rai nna, shawng nnan na hka lang ai lam hpe grai shayawm kau ya ai.
II. Shani shagu bungli galaw ai hta Makeup Hka lang ai lam (Hka matut manoi sum mat ai a madung npawt nhpang)
Closed-loop system ni a shani shagu na hka sum ai lam gaw shinggan na hka lim ai circuit hta sha byin ai, kata na hka lim ai lam hpe mung n yu n hkan galaw mai ai. Total makeup hka n-gun hta hka lim ai lam, hka lim ai lam hte hka lim ai lam ni lawm ai.Madung Formula: Hkying hkum mi hta hka n-gun=Hka lim ai lam sum ai + Hka lim ai lam sum ai + Hka lim ai lam sum ai
Hka lim ai lam sum mat ai (70%–80% yawng sum mat ai, hka hpe madung jai lang ai)
Katsi ai hpe hka garan ai hka hpe hka lim ai hku nna shapraw kau nna, nbung katsi ai shai hkat ai lam gaw hka lim ai atsam hpe hkrak dawdan ya ai. Industrial empirical standard: shang wa ai hte pru wa ai hka garan ai hka lapran na nbung katsi ai shai hkat ai lam 5℃rai yang, hka garan ai hka lim ai lam yawng a 0.54% hte maren rai nga ai.Tengman ai hku sawn la ai ladat: WE=Δt×L×4.1868÷2520 Gara kaw Δt=hka garan ai hka n-gun shai hkat ai;
L=hkying hkum mi hta hka lim ai. Ga shadawn, 200 m3/h hka lim ai hte 5℃nbung katsi ai shai hkat ai hte, hkying hkum mi hta hka lim ai lam sum ai gaw 1.08 m3 daram hkrat sum ai.
Katsi ai nbung laru aten hta wet-bulb nbung katsi ai lam rawt jat wa ai shaloi, hka lim ai lam sum ai lam gaw loi mi rawt jat wa nna, hka lim ai lam hta 0.6%–0.8% du hkra rai nga ai.
Drift sum mat ai
Hka hpe yeng seng kau ya ai jak ni gaw hka n-gun hpe pat shingdang ya ai majaw, pat da ai-loop system ni a matu grai n law ai hka lim ai lam hpe byin shangun ai, hka lim ai hka n-gun a 0.001%–0.1% sha rai nga ai. Premium arung arai ni gaw 0.05% npu na drift sum ai hpe hkang lu ai, hka lit n nga ai daram byin shangun ai, 2%–3% drift sum ai hpaw da ai tower ni hta grau kaja ai.
Blowdown Dilution sum mat ai
Salt ni gaw aten galu-hka lim mat ai hpang, hka lim ai hka hta shinggyin hpawng nga ai, dai majaw, hka lim ai lam hpe hkang lu na matu, hka lim ai lam hpe 3 kaw nna 5 du hkra galaw ra ai.
Laksan masat masa galaw ai ladat: Hka lim ai n-gun=Hka lim ai n-gun yawm mat ai ÷ (Concentration Cycle − 1) Closed-loop system ni hta hka lim ai n-gun kaji ai majaw, nbung lim ai n-gun n law ai hte hka lim ai n-gun n law ai. Hka a hkam kaja lam hpe grai sadi maja let hkang zing ai ladat ni gaw, hka lim ai aten hpe galu shangun nna, makeup hka ra ai lam hpe grau shayawm ya lu ai..
Ndai zawn re ai sum mat ai lam masum hpe hpawng de dat yang, bungli galaw ai masa hta, pat da ai-loop system ni a hkying hkum shagu na makeup hka yawng gaw, hka lim ai hka lim ai hta 0.5%–1.5% sha rai nga ai. Madung process circulation flow de galai shai ai shaloi, hka jai lang ai lam yawng gaw, maren mara masat da ai hpaw da ai katsi ai nta ni a 10%–20% sha rai nga ai.
500 m3/h hpaw da ai-loop process cooling system hpe madung tawn nna shingdaw ai: hpaw da ai nta npawt ni hta hkying hkum mi hta 10–15 m3 makeup hka ra ai, pat da ai-loop ladat ni gaw hkying hkum mi hta 0.5–1.5 m3 sha jai lang ai. Shani shagu hkying hkum 20-matut manoi galaw ai a matu, hka ton 170 jan hpe hkye la lu ai, dai gaw shaning shagu hka ton 50,000 jan hpe hkye la lu ai hte maren rai nna, hka n law ai ginra ni hta hka quota n-gun hpe grai shayawm ya lu ai.
III. Hpaw da ai-Loop System Hka jai lang ai lam hpe hkra machyi shangun ai madung galai shai ai lam ni
Katsi ai n-gun hte grup yin na katsi ai-bulb a katsi ai: katsi ai hte katsi ai nbung laru aten hta hka lim ai lam sum ai lam gaw 20%–30% jat wa ai. Hka n-gun n law ai katsi majan aten hta, zero makeup hka jai lang ai lam hpe lu la na matu, hka lim ai ladat hpe spray shut down hte galaw mai ai.
Hpaji masa: n-gun kaba ai coil ni hte -density kaba ai hka hpe yeng seng kau ya ai jak ni gaw drift sum mat ai hpe shayawm ya ai, kaba ai-capacity sump ni gaw makeup hpe chyahkring hkring bai bang ai hpe shayawm ya ai.
Hka a hkam kaja lam hpe hkang zing ai lam: hka hpe n-gun ja hkra hka garan ai hpe hkap la ai gaw, hka garan ai lam hpe sharawt ya nna, blowdown- hte seng ai hka n-gun hpe shayawm ya ai.
System tightness: kata na hka hkawm ai pipeline ni hte valve ni kaw na hka pru wa ai majaw, san seng ai hka n-gun hpe loi mi jat shangun ai. Galoi mung jep yu ai shaloi, hka lim ai lam hpe 0.05% npu de pat shingdang lu ai.
IV. Hpaga lam hta jai lang ai lam hta tatut jai lang mai ai lam ni
800 m3/h hpaw da ai-loop hpe katsi shangun ai data center ni hte n-gun hpe shinggyin tawn na matu: yawng static hpring ai n-gun 90 m3 grup yin; 1.2–1.8 m3 daram hka lum ai aten hta hkying hkum mi hta makeup hka, katsi ai aten hta zero makeup hka.
400 m3/h hpaw da ai-loop unit gaw, n-gun n rawng ai hka hpe 45 m3, shaning ting hkying hkum mi hta 0.6–1.0 m3 hka hpe n-gun rawng hkra galaw ai.
Aten galu-bungli galaw ai aten hta, pat da ai-loop cooling system ni gaw hka -hkye la ai akyu lahkawng hpe jaw ya ai: kalang -hpring ai n-gun yawm ai hte matut manoi makeup hka ra ai lam n law ai. Dai aten hta, kata na process circulation hka gaw aten galu laman san seng ai hku nga nga ai, hka npawt kaw nna hka n-gun jai lang ai lam hte hka hpe jasan jaseng ai manu jahpu ni hpe shayawm kau ai, bungli galaw ai hka hpe makawp maga ai hte nbung dat dat ai lam hpe shayawm ai tara ni hpe hkan sa ai.
