Abstract
To keep a temperature of an interior of an automotive vehicle at least at a level of an external atmospheric temperature even if the vehicle is parked with an engine being stopped for a long time, an automotive air-conditioning apparatus is composed of a cooling device 12 to be controlled by a controller 13, a pre-cooling device 20 for pre-cooling the interior of the vehicle, and a sub-controller 18 for controlling the pre-cooling device. The pre-cooling device is composed of a cooling thermoelectric element module 22, a ventilation fan 23, a solar battery 21 and a pre-cooling storage battery 24 charged by the solar battery. The sub-controller always operates the pre-cooling device 20 while the vehicle is stopped with the engine being stopped and starts the pre-cooling device 20, for example, one hour prior to a time when the vehicle starts to movement during parking for a long time in an interior parking lot or the like with the engine being stopped so that the temperature of the interior of the vehicle is kept at a temperature that does not so much exceed a set temperature, i.e., at least at the level of the external atmospheric temperature, until the engine is started.
