Abstract
An vehicle air conditioner (A) includes a duct () in which a partition member () forming a first flow path (A) and a second flow path (B) is provided, and a heat pump circuit (A). In the heat pump circuit (A), a first indoor heat exchanger (A) that contributes mainly to heating is located in the first flow path (A) or faces an outlet of the first flow path (A), and a second indoor heat exchanger (B) that contributes mainly to cooling is located in the second flow path (B). The ratio between an internal air and an external air within air flowing through each of the first flow path (A) and the second flow path (B) is adjustable. The duct () is provided with at least one of a heating exhaust port () for discharging air cooled in the second indoor heat exchanger (B) to the outside of the vehicle interior in heating operation, and a cooling exhaust port () for discharging air heated in the first indoor heat exchanger (A) to the outside of the vehicle interior in cooling operation. This configuration enables the air within the vehicle interior, the temperature of which has been adjusted by heating or cooling, to be efficiently utilized without wasting energy by discharging the air as it is to the outside.
