PROBLEM TO BE SOLVED: To provide a vehicle air-conditioning device capable of reducing workload of a compressor without deterioration in heating capability.SOLUTION: An air-conditioning control device, when its heating capacity is excess and a compressor is intermittently driven with the minimum rotation frequency by switching between a step 160 and a step 170 based on determination of a refrigerant pressure in a high pressure side in a step 150, drives an outdoor fan not only when a compressor is turned on but also when the compressor is turned off. This, even when the compressor is turned off and refrigerant circulation of a heat pump cycle is stopped, causes an outdoor heat exchanger to continue to evaporate refrigerant to increase a refrigerant pressure in a low pressure side. |
