    Abstract: A vehicle air conditioner has a compressor, a radiator, a pressure reducer, a cooling heat exchanger, a temperature detector, and a prohibition request output part. The compressor draws and discharges a refrigerant. The radiator dissipates heat of the refrigerant. The pressure reducer decompresses and expands the refrigerant. The cooling heat exchanger cools an air blown into a vehicle compartment. The temperature detector detects a temperature of the cooling heat exchanger. The prohibition request output part outputs a request, which prohibits the idle stop control, to an idle stop controller when the engine is operated. The request prohibits the idle stop control until the temperature of the cooling heat exchanger falls to a temperature being enough cool to cool the air and a required cooling time elapses. The required cooling time is estimated to be required to make a passenger feel cool by the air.

    Abstract: In an air conditioner, a heat medium circuit includes: a first branch part, a first merging part, a second branch part, and a second merging part. A first flow rate adjusting unit is disposed in the heat medium circuit between the first branch part and an outside-air heat exchanger or between the outside-air heat exchanger and the first merging part, and a second flow rate adjusting unit is disposed in the heat medium circuit between the first branch part and the first heater core or between the first heater core and the first merging part. At least one of the first flow rate adjusting unit or the second flow rate adjusting unit is configured to optionally adjust the flow rate of the heat medium, and a controller controls the at least one of the first flow rate adjusting unit or the second flow rate adjusting unit.
