Air conditioner for vehicle

An air conditioner for a vehicle, which conditions air of a vehicle interior, comprising:

• a compressor to compress a refrigerant;
• an air flow passage through which the air to be supplied to the vehicle interior flows;
• a radiator to let the refrigerant radiate heat, thereby heating the air to be supplied from the air flow passage to the vehicle interior;
• an outdoor heat exchanger disposed outside the vehicle interior to let the refrigerant absorb or radiate heat;
• a battery temperature adjustment device to let a heat medium circulate through a battery mounted in the vehicle, thereby adjusting a temperature of the battery;
• and
• a control device,
• wherein the battery temperature adjustment device has a refrigerant-heat medium heat exchanger to perform exchange of heat between the refrigerant and the heat medium, and
• wherein the control device executes:
• a first heating/battery cooling mode to let the refrigerant discharged from the compressor radiate heat in the radiator, decompress the refrigerant from which the heat has been radiated, and then let the refrigerant absorb heat in the outdoor heat exchanger and the refrigerant-heat medium heat exchanger, and
• a second heating/battery cooling mode to let the refrigerant discharged from the compressor radiate heat in the radiator and the outdoor heat exchanger, decompress the refrigerant from which the heat has been radiated, and then let the refrigerant absorb heat in the refrigerant-heat medium heat exchanger.
