Disclosed is an air conditioning apparatus for a vehicle. According to an aspect of the present invention, the air conditioning apparatus for a vehicle comprises: a first temperature sensor to sense an outside air temperature of a vehicle; a second temperature sensor to sense a temperature of a coolant flowing into a heater arranged in an air conditioning case; a third temperature sensor to sense a temperature of air passing through an evaporator arranged on the air conditioning case; a controller to receive temperatures from the first, second, and third temperature sensors; and a memory unit to store the temperature received from the first temperature sensor at the time when the engine of the vehicle is turned off. The controller predicts the outside air temperature of the vehicle based on the temperatures received from the second and third temperature sensors and the temperature stored in the memory unit if a temperature is not received from the first temperature sensor until the time when a preset first time elapses after starting the engine of the vehicle.

    차량용 공조장치가 개시된다. 본 발명의 일 측면에 따르면, 차량의 외기온도를 감지하는 제1 온도센서; 공조케이스 내부에 구비된 히터로 유입되는 냉각수의 온도를 감지하는 제2 온도센서; 상기 공조케이스에 배치된 증발기를 통과하는 공기의 온도를 감지하는 제3 온도센서; 상기 제1, 제2, 제3 온도센서로부터 온도를 수신하는 컨트롤러; 및 차량의 시동 오프(OFF) 시점에 상기 제1 온도센서로부터 수신된 온도를 저장하는 메모리부를 포함하고, 상기 컨트롤러는 차량의 시동 온(ON) 후 기 설정된 제1 시간이 경과된 시점까지 상기 제1 온도센서로부터 온도가 수신되지 않으면 상기 제2, 제3 온도센서로부터 수신된 온도와 상기 메모리부에 저장된 온도를 기초로 차량의 외기온도를 예측하는 차량용 공조장치가 제공될 수 있다.
