    • A vehicle air conditioner includes a cooling heat exchanger arranged in a casing, a compressor control portion which controls a compressor such that a cooling temperature at the cooling heat exchanger approaches a target cooling temperature, and a dryness determination portion which determines whether an outer surface of the cooing heat exchanger is dry or not based on a humidity in the casing. A target temperature determination portion determines the target cooling temperature to be any one of target temperatures including a first target temperature that is lower than a dew-point temperature in the casing, when the dryness determination portion determines that the cooling heat exchanger is not dry. The target temperature determination portion determines the target cooling temperature to be any one of the target temperatures other than the first target temperature, when the dryness determination portion determines that the cooling heat exchanger is dry.
    • 一种车辆用空调机,其具备:设置在壳体内的冷却热交换器,对冷却热交换器的冷却温度接近目标冷却温度的压缩机进行控制的压缩机控制部;以及干燥判定部, 冷却热交换器基于壳体中的湿度干燥或不干燥。 目标温度判定部,当所述干燥度判定部判断为所述冷却用热交换器不干燥时,将所述目标冷却温度判断为包括低于所述壳体的露点温度的第一目标温度的目标温度中的任意一个。 当干燥度确定部确定冷却热交换器干燥时,目标温度确定部分将目标冷却温度确定为除第一目标温度之外的目标温度中的任何一个。
