Claim 2:
3. The air conditioner for the vehicle of claim 2, wherein passing of the coolant through said expansion valve for cooling and said heat exchanger for cooling and passing of the coolant through said expansion valve for battery and said heat exchanger for battery are respectively executed after the coolant passes through said external heat exchanger, there is provided a switching device to switch a flow pattern of the coolant after passing through the external heat exchanger among a first pattern, a second pattern, and a third pattern, the first pattern being configured such that the coolant passes through the expansion valve for cooling and the heat exchanger for cooling but the coolant does not pass through the expansion valve for battery and the heat exchanger for battery, the second pattern being configured such that the coolant passes through the expansion valve for battery and the heat exchanger for battery but the coolant does not pass through the expansion valve for cooling and the heat exchanger for cooling, the third pattern being configured such that the coolant passes through the expansion valve for cooling and the heat exchanger for cooling and the coolant pass through the expansion valve for battery and the heat exchanger for battery, and said pressure sensor is configured to detect the pressure of the coolant at a timing after the coolant passes through the external heat exchanger.
