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 () for circulating a heat medium in a battery () to cool the same, a refrigerant-heat medium heat exchanger () for exchanging heat between at least part of the refrigerant flowing out from an outdoor heat exchanger () and the heat medium circulating in the battery temperature adjustment device, and an auxiliary expansion valve () for decompressing the refrigerant flowing into the refrigerant-heat medium heat exchanger. A control device controls a compressor () 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.
