DETERMINATION DEVICE, REFRIGERATOR, DETERMINATION METHOD IMPLEMENTED BY DETERMINATION DEVICE, SETTING METHOD IMPLEMENTED BY REFRIGERATOR, AND PROGRAM

To provide a determination device capable of determining whether or not it is in a state where setting should be changed from backup operation OFF setting to backup operation ON setting.SOLUTION: A determination device comprises a determination section by which, on the basis of at least one of a time of operation stop of a refrigerator, coordinates of the refrigerator during the operation stop of the refrigerator, a first temperature difference that is a difference between an internal temperature of the refrigerator and a preset temperature of the refrigerator and a second temperature difference which is a difference between the internal temperature of the refrigerator and an outside air temperature of the refrigerator, it is determined whether or not it is in a state where setting should be changed from first setting in which power is prevented from being supplied to the refrigerator while a vehicle provided with the refrigerator is stopped to second setting in which power is supplied from a first power source included in the vehicle while the vehicle is traveled and power is supplied from a second power source dedicated to the refrigerator to the refrigerator while the vehicle is stopped.SELECTED DRAWING: Figure 2 【課題】バックアップ運転オフ設定からバックアップ運転オン設定へ設定を変更すべき状態であるか否かを判定することができる判定装置を提供する。【解決手段】判定装置は、冷凍機が運転停止している時間、前記冷凍機が運転停止しているときの前記冷凍機の座標、前記冷凍機の庫内温度と前記冷凍機の設定温度との差である第１温度差、及び、前記冷凍機の庫内温度と前記冷凍機の外気温度との差である第２温度差のうちの少なくとも１つに基づいて、前記冷凍機を備える車両が停車しているときに前記冷凍機へ電力が供給されないようにする第１設定から、前記車両が走行しているときに前記車両が備える第１電源から前記冷凍機へ電力が供給され、前記車両が停車しているときに前記冷凍機専用の第２電源から前記冷凍機へ電力が供給される第２設定へ設定を変更すべき状態にあるか否かを判定する判定部、を備える。【選択図】図２
