ABSTRACT:
In accordance with this invention, an automotive air conditioner is provided in which operational efficiency of the air conditioner is enhanced and comfortable operation may be performed with little vibration. The automotive air conditioner comprises a front seat cooling apparatus, a rear seat cooling apparatus, an environment detection device for detecting air-conditioning environment conditions, and a controller for controlling the operation of the cooling apparatuses on the basis of air-conditioning environment conditions detected by the environment detection device. A compressor drive source for either one of the cooling apparatuses is a vehicle drive source, and a compressor drive source of the other cooling apparatus is a drive source that is independent of the vehicle drive source. More preferably, the drive source that is independent of the vehicle drive source uses an electric motor. Also, the air-conditioning environment conditions to be detected by the environment detection device includes at least one of a passenger compartment temperature, an outside temperature, a solar radiation amount and a passenger set compartment interior temperature.
