  • Vehicle air conditioner with flow area adjustment of fluid in heating heat exchanger
    Patent number: 6679434
    Abstract: In a vehicle air conditioner, a flow control member is disposed in an inlet tank of a heating heat exchanger for heating air to be blown into a passenger compartment using a fluid as a heating source. In the heating heat exchanger, a ratio between a first area where the fluid flows, and a second area where the fluid does not flow is changed by controlling an operation position of the flow control member. Thus, a flow ratio between hot air from the first area of the heating heat exchanger and cool air from the second area thereof can be adjusted, so that the temperature of air blown into the passenger compartment can be adjusted.
