Abstract
A vehicle air conditioning device is provided which is capable of accurately judging the need for temperature regulation of an object of temperature regulation mounted in a vehicle and efficiently performing temperature regulation. A compressorto compress a refrigerant, an indoor heat exchanger (radiatorand heat absorber) for exchanging heat between air supplied to a vehicle interior and the refrigerant, an outdoor heat exchangerdisposed outside the vehicle interior, and a control deviceare provided to perform air conditioning of the vehicle interior. An equipment temperature adjusting devicefor adjusting the temperature of the object of temperature regulation mounted in the vehicle is provided. The control device controls the equipment temperature adjusting deviceon the basis of a gradient (ΔTw) of a change in an index indicating the temperature of the object of temperature regulation.
