東京とヨーロッパ5都市における空調機負荷特性の比較

Abstract

This paper describes the simulation results of annual air conditioning load in the model office building in Tokyo and five European cities, Rome, Zurich, Paris, Frankfurt and London. The purpose of this study is to describe the characteristic of heating and cooling energy consumption in Japan in comparison with Europe where space heating is considered more important than cooling. From the comparison of annual air conditioning loads in the office building, the total load in Tokyo showed the greatest value which is 1.4 times of the total load in Paris. Since the space cooling load of office buildings is affected by solar radiation through windows and internal heat gains, the annual space cooling load is much greater than the space heating load in all cities. However, for the air conditioning coil loads, the heating load is greater than the cooling load in the most European cities due to cooling effect of outdoor air for ventilation reauirment. From the simulation results, it was confirmed that cooling is primarily important in Tokyo in comparison with the European cities where the heating shared the largest portion even for the office building.
