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 = 7.4 °C , Ta = 19.9 °C , To = 16.8 °C, Psp = 2.69 kW
太陽光発電+Li電池蓄電システムの発電量は-0.49 kWで、計算機室への送電量はPsp = 2.69 kW(力率 f = cosφ = 0.92)です。推定ですが、現在の外気吸入による冷却能力Poaは1.6 kWです。アメダスによると,2018年01月22日 04時00分の山形県米沢市の1時間の平均気温は,-2.7℃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
