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.

[ What is claimed is:] [1.] In an air-conditioning apparatus for cooling an internal passenger chamber of an automotive vehicle having a cooling device driven by an engine of the vehicle, a controller for controlling the cooling device, a pre-cooling device driven by an energy source other than the engine for pre-cooling the interior passenger chamber of the vehicle, and a sub-controller for controlling the pre-cooling device, the improvement wherein:the pre-cooling device comprises a cooling thermoelectric element module for cooling the interior passenger chamber of the vehicle, a ventilation fan for discharging air from the interior passenger chamber of the vehicle to the outside thereof, and a solar battery for supplying electric power to the cooling thermoelectric element module and the ventilation fan; andthe sub-controller includes means for performing a pre-cooling control operation during which the ventilation fan is made to operate to reduce the temperature in the interior passenger chamber of the vehicle when the temperature of the interior passenger chamber of the vehicle is equal to or higher than a first set temperature, and the cooling thermoelectric element module is made to operate to reduce the temperature in the interior passenger chamber of the vehicle when the temperature of the interior passenger chamber of the vehicle is equal to or higher than a second set temperature.
