Tamarta xarunta xogta Qaabka tooska ah

Waxaad tahay injineerka xarunta hoolka xogta ee 1 MW: chiller-ro, wareeg biyo qabow, baytariyo UPS ah iyo koronto-dhaliye kayd ah. Kuleylku wuxuu ka socdaa server-yada ilaa hawada, biyaha iyo dibadda — wati kasta oo aad ku bixiso qaboojinta waxay ka muuqataa PUE.

Xakamayaal

Chiller #1…#n. Chiller cusub oo la bilaabay wuxuu u baahan yahay 5 daqiiqo ka hor inta uusan qaboojin.

Biyo ka kulul = waxtar chiller oo wanaagsan, laakiin albaabada gelitaanka server-yada oo kuleylan.

Shaqooyin xirmo ah oo dib loo dhigay: kuleyl iyo awood yar hadda.

Waxay isticmaashaa hawada qabow ee dibadda iyada oo dhex marta qaboojiye engegan marka ay qabow tahay si ku filan.

Waxay uumi-baxisaa biyo si ay u qaboojiso hawada condenser-ka: waxtarka way fiicnaadaa, laakiin biyo ayaa la isticmaalaa.

Waxaa loo baahan yahay oo keliya haddii bilawga toos ahi guuldareysto. Waxay qaadataa 3 daqiiqo.

Wuxuu tirtiraa go'idda badbaadada ee chiller marka cilladda la hubiyo; waa la aqbalaa laga bilaabo 15 daqiiqo kadib go'idda.

Xaaladaha dhibaatada

Heerka 1 · Chiller oo joogsada xilliga ugu sarreeya

Galab kulul, 32 °C dibadda. IT waxay qaadataa 850 kW iyadoo ku shaqaynaysa laba ka mid ah saddex chiller, biyaha qabowna waxay ku socdaan 16 °C si tamar loo badbaadiyo — taas oo gelitaannada server-ka uga tagta oo keliya qiyaastii 2 K ka hooseeya xadka ASHRAE ku taliyo. Hal chiller ayaa ku dhow inuu go'o. Gelitaannada ku hay xadka lagu taliyay, shaqada IT ha sii socoto, qalabkana ku soo celi kayd buuxa.

  • Gelitaanku marna ha ka badnaan 27 °C
  • Gelitaanka ≤ 25 °C dhammaadka (xaalad caadi ah)
  • Celceliska culayska IT ≥ 750 kW (ha damin server-yada oo keliya)
  • Saddexda chiller oo dhammi diyaar mar kale dhammaadka (cutubka go'ay dib loo dejiyay)

Heerka 2 · Mowjad kuleyl iyo codsi jawaab-celin dalab

Heerkulka dibaddu wuxuu ka kacaa 30 °C ilaa 42 °C. Chiller-aduna awood iyo waxtar way lumiyaan. Kadibna hawlwadeenka shabakaddu wuxuu soo saaraa codsi jawaab-celin dalab: ku hay awoodda xaruntan 900 kW ka hooseeya nus saac.

  • Gelitaanku marna ha ka badnaan 27 °C
  • Celceliska awoodda xarunta ≤ 900 kW inta codsigu socdo
  • Celceliska culayska IT ≥ 720 kW inta xaaladdu socoto

Heerka 3 · Shabakaddu way go'day, koronto-dhaliyuhu ma bilaabmo

Shabakaddu way go'daa. Koronto-dhaliyuhu waa inuu qabtaa toban ilbiriqsi gudahood — markan ma sameeyo. Server-yadu waxay ku shaqeynayaan baytariyo UPS ah oo leh tamar ku dhow toban daqiiqo, chiller-aduna way dhimatay.

  • Ma jiro joogsi IT ah
  • Baytarigu marna ha ka hoosayn 72 %
  • Gelitaanku marna ha ka badnaan 25 °C

Aasaas — moodelka ka dambeeya tirooyinka

Xiriir kasta oo jilaha isticmaalo, iyo ilaha uu ka yimid. Mudnaanta lagu calaamadiyay malo-awaal waa hagaajin muunad ah.

Isu-dheelitirka tamarta ee nood-ka hawada: server-yadu hawada way kululeeyaan, koyil-ada qaboojintu kuleylka way u gudbiyaan biyaha qabow.
C_air · dT_air/dt = P_IT + P_fans − Q_CRAH, Q_CRAH = UA · (T_air − T_chw)[4][11]Malo-awaal: awoodda kaydinta kuleylka, gudbinta koyilka, cabbirka chiller-ka iyo tamarta baytariga waa qiyam muunad ah oo loogu talagalay hoolka 1 MW.
Isu-dheelitirka tamarta ee nood-ka biyaha: culeyska kuleylka ee wareegga ayaa jebiya farqiga u dhexeeya culayska kuleylka iyo awoodda chiller-ka.
C_w · dT_chw/dt = Q_CRAH − Q_chillers − Q_econ, C_w = 20 m³ × 4186 J/(kg·K)[4]
Waxtarka chiller-ka oo ah qayb go'an oo ka mid ah xadka Carnot — wuu hoos u dhacaa marka hawada dibaddu kululaato. Heerkulka evaporator-ku wuxuu raacaa heerkulka dhabta ah ee wareegga biyaha qabow (2 K ka hooseeya), ma aha heerka la dejiyay, sidaas darteed wareeg kululaada go'idda kadib wuxuu wakhti gaaban kor u qaadaa COP-ga.
COP = 0.45 · T_evap / (T_cond − T_evap), T_evap = T_chw − 2 K, T_cond = T_air,out + 12 K [K][5]Malo-awaal: awoodda kaydinta kuleylka, gudbinta koyilka, cabbirka chiller-ka iyo tamarta baytariga waa qiyam muunad ah oo loogu talagalay hoolka 1 MW.
Waxtarka isticmaalka awoodda (PUE): awoodda guud ee xarunta oo loo qaybiyay awoodda IT (1.0 waa kan ugu fiican).
PUE = P_facility / P_IT[1][12][8]
Waxtarka isticmaalka biyaha (WUE); biyaha uumi-baxay marka loo eego tamarta loo baahan yahay qaboojinta hawada condenser-ka.
WUE = water (L) / IT energy (kWh); evaporation = m_air · c_p · ΔT / h_fg[2][7]
Xadka kuleylka ee ASHRAE ee hawada gelitaanka server-ka.
recommended 18–27 °C · A1 allowable 15–32 °C[3]
Tamarta baytariga UPS waxay dhammaataa iyadoo culayska la ilaaliyay la socdo ilaa koronto-dhaliyuhu qabto.
E_batt(t+Δt) = E_batt − (P_IT + P_fans + P_pumps)/η_UPS · Δt (energy balance); generator ≤ 10 s[6]Malo-awaal: awoodda kaydinta kuleylka, gudbinta koyilka, cabbirka chiller-ka iyo tamarta baytariga waa qiyam muunad ah oo loogu talagalay hoolka 1 MW.
Marka la beddelo isha awoodda, chiller-aduna way istaagaan oo waa in dib loo bilaabaa.
chiller restart after any power transfer = 5 min (quick-start; typical 10–15 min)[11]
Qiiqa ka imaanaya xoogga korontada shabakadda, ama dheeslada marka koronto-dhaliyuhu shaqeynayo.
CO₂ = P_facility × grid intensity (≈450–650 g/kWh in the scenarios); diesel ≈ 2.69 kg CO₂/L[9][10][13]
Mudnaanta kale ee hawlgalka ee uu moodelku isticmaalo.
chillers 3 × 450 kW, derate 2.5 %/K above 35 °C · adiabatic effectiveness 70 % · loop P-gain 150 kW/K · IT shutdown at 40 °C inlet · manual generator start 3 min · chiller trip reset accepted 15 min after the trip · battery 150 kWh (≈10 min at full load), recharge 10 %/h · UPS η 95 %Malo-awaal: awoodda kaydinta kuleylka, gudbinta koyilka, cabbirka chiller-ka iyo tamarta baytariga waa qiyam muunad ah oo loogu talagalay hoolka 1 MW.
