Abstract
The vehicle air conditioning device includes a compressor, a radiator, an outdoor heat exchanger, and an air conditioning controller, and a cabin is, air conditioned with power supplied from a battery. The air conditioning controller can perform air conditioning operation that causes a refrigerant from the compressor to radiate heat in the radiator, decompresses the refrigerant, causes the refrigerant to absorb heat in the outdoor heat exchanger so as to heat the cabin, and defrosting operation that causes the refrigerant from the compressor to radiate heat in the outdoor heat exchanger so as to defrost the outdoor heat exchanger, and determines whether it is possible to perform the defrosting operation on the basis of outside humidity.
