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 = 14 °C , Ta = 20.8 °C , To = 19.9 °C, Psp = 2.43 kW
太陽光発電+Li電池蓄電システムの発電量は-0.5 kWで、計算機室への送電量はPsp = 2.43 kW(力率 f = cosφ = 0.90)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。アメダスによると,2017年04月23日 22時00分の山形県米沢市の1時間の平均気温は,4.3℃です.アメダスデータは、MetBrokerからMetXML形式のデータを定期的に取得して、更新しております。
P oa = (To - Ti) × 0.288×500× 4.185÷ 3600
