Abstract: A vehicular air conditioning device is provided which is capable of cooling a heat medium of a battery temperature adjustment device by a refrigerant in a refrigerant circuit to improve operation efficiency when a battery is to be cooled. The vehicular air conditioning device includes a battery temperature adjustment device (61) for circulating a heat medium in a battery (55) to cool the same, a refrigerant-heat medium heat exchanger (64) for exchanging heat between at least part of the refrigerant flowing out from an outdoor heat exchanger (7) and the heat medium circulating in the battery temperature adjustment device, and an auxiliary expansion valve (73) for decompressing the refrigerant flowing into the refrigerant-heat medium heat exchanger. A control device controls a compressor (2) or the auxiliary expansion valve on the basis of a temperature Tw of the refrigerant of the refrigerant-heat medium heat exchanger to thereby adjust a battery temperature Tb to a target battery temperature TBO.

Abstract: An object of the present invention is to provide a vehicle air conditioning device that can solve the decrease of a circulation refrigerant quantity while effectively using the heat of a temperature control object in heating a cabin. The heating operation of a vehicle air conditioning device (1) includes an external air heat absorption heating mode for heating a cabin in a manner that a refrigerant discharged from a compressor (2) radiates heat in a radiator (4), the refrigerant is decompressed, and then the refrigerant absorbs heat in an outdoor heat exchanger (7), and a temperature control object heat absorption heating mode for heating the cabin in a manner that the refrigerant absorbs heat in a refrigerant-heat medium heat exchanger (64), and these modes are performed while being switched. The heating operation is started in the external air heat absorption heating mode.

Abstract: There is provided a vehicle air conditioning apparatus capable of removing frost formed on an outdoor heat exchanger at the same time as cooling of a battery. The vehicle air conditioning apparatus performs the operation in a first battery cooling mode, a second battery cooling mode, or a solo battery cooling mode, when it is determined that the battery needs to be cooled and also determined that the frost formed on the outdoor heat exchanger needs to be removed. By this means, it is possible to cool the battery and melt the frost formed on the outdoor heat exchanger at the same time by the battery cooling operation, and therefore it is possible to reduce the power consumption compared to the case where the battery cooling operation and the defrosting operation are performed individually.
