A frosting suppression device (10) for a vehicle is provided with: a grille shutter (12) disposed in front of an outdoor heat exchanger for heating the interior of a vehicle cabin; a shutter control unit (21) that controls the opening and closing of the grille shutter (12); and a weather information acquisition unit (18) that acquires weather information including a temporal change in the predicted outside air temperature at the current position of the vehicle. The shutter control unit (21) performs a frost prediction for predicting whether or not frost will occur in the outdoor heat exchanger using the predicted outside air temperature at the start of parking of the vehicle, and in the frost prediction, it is predicted that frost will occur in the outdoor heat exchanger when the predicted outside air temperature is equal to or less than a predetermined temperature. The shutter control unit (21) closes the grille shutter (12) before a predicted time during which the outdoor heat exchanger is frosted.
车辆用结霜抑制装置(10)包括:格栅开闭器(12),配置于比用于车厢内的制热的室外热交换器靠前侧;开闭器控制部(21),控制格栅开闭器(12)的开闭;以及气象信息获取部(18),获取包括车辆的当前位置处的预测外部空气温度的时间变化的气象信息。开闭器控制部(21)在车辆泊车开始时使用预测外部空气温度来进行预测在室外热交换器处是否会发生结霜的结霜预测,在结霜预测中,在预测外部空气温度成为规定温度以下的时间预测在室外热交换器处会发生结霜。开闭器控制部(21)在室外热交换器的结霜的预测时间之前关闭格栅开闭器(12)。
