Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for evaluating a condition of an air conditioner for a vehicle capable of precisely predicting occurence of a failure of the air conditioner in advance, using data acquired by monitoring a railway vehicle apparatus.SOLUTION: This evaluation method includes: a first step to receive and to store information of measured compartment temperatures collected by a data collection system mounted on a railway vehicle; a second step to calculate, per vehicle and per day, cycle time during which the measured compartment temperatures surpass a target temperature based on the stored information of the measured compartment temperatures and information of the target temperature; and a third step to evaluate a condition of an air conditioner for a vehicle using the cycle time as an indicator.SELECTED DRAWING: Figure 6 【課題】 鉄道車両の機器モニタリングデータを利用して、空調装置の故障発生を高い精度で事前に予測することができる車両用空調装置の状態評価方法を実現する。【解決手段】 鉄道車両に搭載されたデータ収集システムによって収集された車内実測温度情報を受信し記憶する第1ステップと、記憶された車内実測温度情報および目標温度情報に基づいて、車内実測温度が目標温度を超えているサイクル時間を車両ごとに日単位で算出する第2ステップと、前記サイクル時間を指標として車両用空調装置の状態を評価する第3ステップと、を含むようにした。【選択図】 図6
