PROBLEM TO BE SOLVED: To suppress deterioration of an occupant's sense of being heated occurring when an exterior heat exchanger of a vehicular air conditioner, which includes a heat pump cycle, is defrosted.SOLUTION: When occurrence of frost deposition in an exterior heat exchanger 16 is recognized and pre-air conditioning is carried out, the exterior heat exchanger 16 is defrosted. Accordingly, even when the occurence of frost deposition in the exterior heat exchanger 16 is recognized, if an occupant stays aboard a vehicle compartment and pre-air conditioning is not carried out, switching to a refrigerant circuit in a defrosting mode is inhibited in order to thus suppress deterioration of an occupant's sense of being heated occurring when the exterior heat exchanger 16 is defrosted. |
