Vehicle air conditioning device

A vehicle air conditioning apparatus for air-conditioning inside of a cabin, the vehicle air conditioning apparatus comprising:

• a compressor for compressing a refrigerant;
• a radiator for causing the refrigerant to dissipate heat to heat air to be supplied into the cabin;
• a heat absorber for causing the refrigerant to absorb heat to cool air to be supplied into the cabin;
• an outdoor heat exchanger provided outside the cabin;
• a control device;
• and
• an equipment temperature adjusting device for circulating a heating medium to a battery and a predetermined temperature-adjusted object other than the battery, the battery and the temperature-adjusted object being mounted on a vehicle, to adjust a temperature of the battery and a temperature of the temperature-adjusted object, wherein
• the equipment temperature adjusting device includes:
• a circulating device for circulating the heating medium to the battery and the temperature-adjusted object;
• a refrigerant-heating medium heat exchanger for exchanging heat between the refrigerant and the heating medium to cause the refrigerant to absorb heat from the heating medium;
• an air-heating medium heat exchanger for exchanging heat between outdoor air and the heating medium;
• and
• a flow passage switching device for controlling circulation of the heating medium to the battery and the temperature-adjusted object,
• the control device is capable of executing at least an air conditioning operation for heating the inside of the cabin by causing the refrigerant discharged from the compressor to dissipate heat in the radiator, decompressing the refrigerant heat-dissipated, and then causing the refrigerant to absorb heat in the outdoor heat exchanger and
• an air conditioning operation for cooling the inside of the cabin by causing the refrigerant discharged from the compressor to dissipate heat in the outdoor heat exchanger, decompressing the refrigerant heat-dissipated, and then causing the refrigerant to absorb heat in the heat absorber in a switching manner, and
• the control device is capable of decompressing the refrigerant and then passing the refrigerant to the refrigerant-heating medium heat exchanger to cause the refrigerant to absorb heat from the heating medium in each of the air conditioning operations.
