Evaluation of Estimation Method for the Fuel Consumption under the A/C Operating Condition in the Summer


It was known that the vehicle fuel consumption under the mobile air conditioner (A/C) operation is increased in accordance with increase of the specific enthalpy in the test cell. In this study, the authors evaluated the estimation method for the fuel consumption under the A/C operating condition in the representative summer condition based on the relationship between the specific enthalpy in the test cell and fuel consumption. It was found that the difference between the estimated fuel consumption and the measured fuel consumption in the environmental condition of 71 kJ/kg(DA) was approximately 1.6%.エアコン使用時の自動車の燃費は,エアコン設定や環境条件によって変化する.本研究では,乗用車8台を用いて,30℃環境における燃費を推計する方法を調査した.常温環境2点における燃費と試験室空気の比エンタルピの関係を用いて30℃環境のエアコン使用時燃費を推計した場合,実測値に対して1.6%程度の範囲で推計できた.
