To achieve heat recovery of air in a vehicle cabin while suppressing equipment cost.SOLUTION: A vehicle air conditioner includes: a refrigerant circuit; a heat medium circuit heat-exchanging with the refrigerant circuit; a main air conditioner; an auxiliary air conditioner provided with a heat exchange part of the heat medium circuit; and a control device controlling operations of the refrigerant circuit, the heat medium circuit, the main air conditioner and the auxiliary air conditioner. The control device executes a heat recovery mode recovering heat from the air in the vehicle cabin in the auxiliary air conditioner when the execution determination part determines that air conditioning by the auxiliary air conditioner is unnecessary.SELECTED DRAWING: Figure 1
