サーバ室の温度監視・太陽光発電受電モニター(現在開発中)

計算機室の概略図 Ti = 21.5 °C , Ta = 22.5 °C , To = 22.1 °C, Psp = 1.75 kW
太陽光発電+Li電池蓄電システムの発電量は-0.29 kWで、計算機室への送電量はPsp = 1.75 kW(力率 f = cosφ = 0.83 ・)です。推定ですが、現在の外気吸入による冷却能力Poaは.1 kWです。
P oa = (To - Ti) × 0.288×500× 4.185÷ 3600

図 2026年05月13日 19:00から2026年05月14日 19:00のサーバ室の温度変化
青線、黒線、赤線、緑線は、それぞれ吸気温度、周辺温度、排気温度、米沢市の気温である。
