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.
