Series Output ( kW ) Efficiency ( % ) Loss ( kW ) Power Consumption ofAir-Conditioning Unit ( kW )
Conventional UPS 80 88 10.9 3.9
8000 Series 80 98 1.6 0.45
Comparison in Electric Charge ( Example at 100kVA )
*When operated continuously all year around under 100% load.
Item Result Remarks
Difference in UPS loss 9.3kW =10.9kW-1.6kW
Difference in air-conditioning power consumption 3.45kW =3.9kW-0.45kW
Electric power improved 12.75kW =9.3kW+3.45kW
Annual electric energy reduced 111,690kWh =12.75kW x 24h x 365days
Electric charge saved (Annual) 1.68 million yen / year Electricity rate of 15 yen/kWh
Amount of CO2 cut back 41.4t CO2 emission rate of 0.371kg-amount of CO2/kWh
The 8000 Series leads to a substantial cutback of running cost and reduction of CO2 emissions.It can therefore be termed environment-friendly and suitable Green-IDC systems.
