Zusammenfassung
A data center(DC) demands air-conditioning power as large as the 1/3-1/2 of total electricity
consumption.Thus, energy saving of cooling power of DC yields considerable effect on both
economic and environmental views.Photovoltaic (PV) and absorption refrigerator with gas boiler or
cogeneration systems(CGS) are possible power saving options. The waste warm air from DC would be
utilized for greenhouse heating when DC and greenhouse locate near in the suburbs. In this study, the
authors develop an energy network model to assess the potential contribution of DC as a major electric
power and chilled air consumer as well as the warm air supplier in a district to the energy efficiency
improvement. The evaporation heat of LNG utilization is also considered as well as PV, CGS. This
model is applied to the cases of the urban area in Tokyo which involves athletic center, shops and
hospital and the suburbs including greenhouse and then compared.
Key word: data center, distributed energy systems, urban and suburbs
