PROBLEM TO BE SOLVED: To provide a low-costed vehicle air conditioning device capable of securing comfortableness inside a cabin during defrosting operation.SOLUTION: A vehicle air conditioning device includes: an indoor condenser where a heat exchanging medium compressed by a compressor flows into to radiate the heat; an outdoor heat exchanger where the heat exchanging medium flows into to exchange the heat with the outside of a cabin; and an indoor heat exchanger where the heat exchanging medium flows into to exchange the heat with the inside of the cabin. When a determination that the outdoor heat exchanger is frosted is done (S12-S16) during the operation with a first heating mode for heating the inside of the cabin (S10), after operating with a second heating mode stronger than the first heating mode (S18), operation is changed to a defrosting mode for defrosting by leading the high-pressure heat exchanging medium into the outdoor heat exchanger to radiate the heat (S20). |
