An air-conditioning apparatus for allowing the temperatures of a first air-conditioning zone and a second air-conditioning zone to quickly approach the respective set temperatures by properly controlling the air flow rate and the ratio of fresh/recirculated air, even when the set temperatures differ

An air-conditioning apparatus for allowing the temperatures of a first air-conditioning zone and a second air-conditioning zone to quickly approach the respective set temperatures by properly controlling the air flow rate and the ratio of fresh/recirculated air, even when the set temperatures differ from one another. The device includes a controller that determines whether the system is in a transitional period or in a steady state based on the deviation of the compartment temperature detected by the compartment temperature sensor from the first and second set temperatures for the first and second zones. If a determination is made that the system is in a transitional period, the controller acts to determine the flow rates of air being supplied to respective blowers as well as making the determination concerning the guidance ratio of the fresh to recirculated air.
