An air-conditioning device for a vehicle is provided with: a condenser in which a high-temperature and high-pressure refrigerant discharged from a compressor flows and which heats air passing through the periphery thereof; an evaporator in which a low-temperature and low-pressure refrigerant flows and which absorbs heat from air passing through the periphery thereof; and a switching unit which switches air flow according to the time when the vehicle is heated, cooled, or dehumidified and heated. The switching unit causes the air passing through the periphery of the condenser to flow out into a vehicle interior when the vehicle is heated, causes the air passing through the periphery of the evaporator to flow out into the vehicle interior when the vehicle is cooled, and causes the air passing through the peripheries of the evaporator and the condenser in sequence to flow out into the vehicle interior when the vehicle is dehumidified and heated. According to the above aspect, switching between cooling, heating, and dehumidification heating can be performed only by switching the air flow in the air-conditioning device for the vehicle. |
