본 발명은 차량용 공조장치에 관한 것으로서, 저외기온 조건에서는 낮은 외기온도에 대응하여 "증발기 목표온도"를 하향 제어함으로써, "증발기 목표온도"보다 낮은 저외기온 조건에서의 에어컨 작동 제한과, 그로 인한 디포깅 장치 작동 제한을 방지할 수 있고, 이를 통해, "증발기 목표온도"보다 낮은 저외기온 조건에서의 창유리 김서림 발생 시, 디포깅 장치가 "증발기 목표온도"와 "외기온도"에 구애받지 않고 창유리의 김서림을 신속하게 제거 처리할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 미리 설정된 증발기 목표온도에 맞춰서 에어컨을 자동 제어하며, 창유리의 김서림 발생 시에 상기 에어컨을 작동시켜 창유리의 김서림을 제거 처리하는 차량용 공조장치에 있어서, 외기온도가 미리 설정된 저외기온 기준온도 이하인지의 여부에 따라 저외기온 조건인지를 판단하고, 판단 결과, 저외기온 조건일 시에, 상기 증발기 목표온도를 하향 제어하는 제어부를 구비한다.

    The present invention relates to a vehicular air conditioning device. According to the present invention, in a low outside air temperature condition, an ″evaporator target temperature″ is controlled downwards in response to a low outside air temperature. Accordingly, it is possible to prevent air conditioner operation limitation in the low outside air temperature condition lower than the ″evaporator target temperature″ and resultant defogging device operation limitation. As a result, during window glass fogging in the low outside air temperature condition lower than the ″evaporator target temperature″, the defogging device is capable of quickly removing and dealing with window glass fogging without being hindered by the ″evaporator target temperature″ and the ″outside air temperature″, which is an object of the present invention. In order to achieve the above object, the present invention is provided with a control unit in the vehicular air conditioning device. The vehicular air conditioning device automatically controls an air conditioner in accordance with a preset evaporator target temperature and removes and deals with window glass fogging by operating the air conditioner when the window glass fogging occurs. The control unit determines the presence or absence of the low outside air temperature condition based on whether the outside air temperature is equal to or less than a preset low outside air temperature reference temperature. When it is determined that the low outside air temperature condition is present, the control unit controls the evaporator target temperature downwards.
