<p>A vehicle air conditioner, which is capable of providing heat even without engine heat and is capable of quickly switching between heating and cooling, is provided. The vehicle air conditioner is provided with: a pressure reducing part for reducing the pressure of a refrigerant; a first heat exchanger for exchanging heat between pressure-reduced refrigerant and ambient air; a compression part for compressing the refrigerant; a second heat exchanger for exchanging heat between compressed refrigerant and ambient air; a first flow passage for leading air that has passed through the first heat exchanger to the vehicle interior; a second flow passage for leading air that has passed through the second heat exchanger to the vehicle interior; a first switching part that is capable of regulating the flow rate of air in the first flow passage; a second switching part that is capable of regulating the flow rate of air in the second flow passage; a third switching unit that is capable of regulating the flow rate of air that has passed through the first heat exchanger and is discharged outside of the vehicle; and a fourth switching part that is capable of regulating the flow rate of air that has passed through the second heat exchanger and is discharged outside of the vehicle.</p> |
