Abstract
A vehicle air conditioner includes a duct in which a partition member forming a first flow path and a second flow path is provided, and a heat pump circuit. In the heat pump circuit, a first indoor heat exchanger that contributes to heating is located in the first flow path or faces an outlet of the first flow path, and a second indoor heat exchanger that contributes to cooling is located in the second flow path. The duct is provided with at least one heating exhaust port for discharging air cooled in the second indoor heat exchanger 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 to the outside of the vehicle interior in cooling operation.
Claims14
A vehicle air conditioner that cools and heats a vehicle interior, the vehicle air conditioner comprising:
- a duct having an internal air inlet port and an external air inlet port at one end portion thereof, and a blowing port at another end portion thereof, wherein an internal space of the duct is separated from the vehicle interior;
- and
- a heat pump circuit comprising
- a first indoor heat exchanger that is disposed in the duct,
- a second indoor heat exchanger that is disposed in the duct, and
- an outdoor heat exchanger disposed outside the vehicle interior,
- wherein the duct is provided with at least one of a heating exhaust port for discharging air cooled in the second indoor heat exchanger 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 to the outside of the vehicle interior in cooling operation, and
- a flow rate of the air discharged to the outside of the vehicle interior through the heating exhaust port or the cooling exhaust port is less than a flow rate of the external air drawn into the duct through the external air inlet port.
A method of controlling a vehicle air conditioner that cools and heats a vehicle interior, the vehicle air conditioner comprising:
- a duct having an internal air inlet port and an external air inlet port at one end portion thereof, and a blowing port at another end portion thereof, wherein an internal space of the duct is separated from the vehicle interior;
- and
- a heat pump circuit comprising a first indoor heat exchanger that is disposed in the duct, a second indoor heat exchanger that is disposed in the duct, and an outdoor heat exchanger disposed outside the vehicle interior,
- wherein the duct is provided with at least one of a heating exhaust port for discharging air cooled in the second indoor heat exchanger 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 to the outside of the vehicle interior in cooling operation,
- the method comprising adjusting a flow rate of the air discharged to the outside of the vehicle interior through the heating exhaust port or the cooling exhaust port and a flow rate of the external air drawn into the duct through the external air inlet port so that the flow rate of the air discharged to the outside of the vehicle interior through the heating exhaust port or the cooling exhaust port is lower than the flow rate of the external air drawn into the duct through the external air inlet port.
