The invention provides: a vehicle air conditioning apparatus in which the evaporator temperature is controlled by using a fin thermal sensor, and that is provided with an independent temperature adjustment function for the left and right sections, wherein a structure capable of preventing an evaporator from freezing is provided; and a control method therefor. A contact temperature sensor 50B is disposed at an evaporator 8 in a region facing a passenger-side space 30 on the downstream side of the evaporator 8. Alternatively, a contact temperature sensor 50A is disposed in contact with the evaporator 8 in a region facing a driver-side space 20 on the downstream side of the evaporator 8, and, when a normal blowing mode is selected, the operating state of a compressor 10 is controlled so thatdetected temperatures (T8a, T8a') detected by the temperature sensor 50 fall between a lower limit (Tsd)min and an upper limit (Tsd)max of a threshold temperature (Tsd), and, when a strong blowing mode is selected, a threshold temperature (Tsp) is set at a greater value than the threshold temperature (Tsd) used when the normal blowing mode is selected.
提供一种在使用翅片感热式传感器来控制蒸发器的温度并且具备左右独立调温功能的车辆用空调装置中能够防止蒸发器冻结的构造以及控制方法。将接触式的温度传感器50B在蒸发器8的面向下游侧的同乘者侧空间30的区域配置于该蒸发器8。或者,将接触式的温度传感器50A在蒸发器8的面向下游侧的驾驶者侧空间20的区域配置为与该蒸发器8接触,在选择了普通吹出模式时,控制压缩机10的工作状态以使得由温度传感器50检测到的检测温度(T,T')处于阈值温度(Tsd)的下限值(Tsd)min与上限值(Tsd)max之间,在选择了集中吹出模式时将阈值温度(Tsp)设定为比选择了普通吹出模式时的所述阈值温度(Tsd)高的值。
