Abstract: An air conditioning device for a vehicle has a compressor, an evaporator, a driving condition detector, a temperature detector, and a controller. The driving condition detector detects a driving condition of the vehicle. The evaporator has a cold storage portion storing the heat from the refrigerant and having phase-change energy in at least two different temperature ranges. The controller (i) maintains the compressor being stopped while a temperature detected by the temperature detector is lower than or equal to the first temperature when the vehicle is in a coasting operation and (ii) maintains the compressor being stopped while the temperature is lower than or equal to the second temperature when the vehicle is stopped. The coasting operation is a driving condition in which a vehicle speed is lower than or equal to a specified speed and an acceleration device of the vehicle is not operated.

Abstract: A cold storage heat exchanger that exchanges heat with air flowing therearound includes: a refrigerant passage through which refrigerant flows; and a cold storage body housing a cold storage medium that exchanges heat with refrigerant flowing through the refrigerant passage and stores an amount of heat from the refrigerant. The cold storage medium includes: a low carbon number paraffin comprising at least one of C12 paraffin and C13 paraffin; and a high carbon number paraffin comprising at least one of C15 paraffin and C16 paraffin. A concentration of the high carbon number paraffin in the cold storage medium is higher than 60 percent by weight and lower than 100 percent by weight. A concentration of the low carbon number paraffin in the cold storage medium is higher than 0 percent by weight and lower than 40 percent by weight.
