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 = 23.9 °C , Ta = 23.1 °C , To = 23 °C, Psp = 1.71 kW
太陽光発電+Li電池蓄電システムの発電量は0.95 kWで、計算機室への送電量はPsp = 1.71 kW(力率 f = cosφ = 0.84 ・)です。推定ですが、現在の外気吸入による冷却能力Poaは-.2 kWです。
P oa = (To - Ti) × 0.288×500× 4.185÷ 3600

図 2026年10月03日 15:00から2026年10月04日 15:00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。
