Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for a vehicle, and more particularly to an air conditioner for cooling and heating a passenger compartment by using a Peltier element.

[0002]

2. Description of the Related Art Conventionally, a Peltier element has been known as a thermoelectric element having a heat exchange function. As shown in FIG.
The Peltier element 5 is an element in which N-type semiconductors 6 and P-type semiconductors 7 are alternately arranged, and by connecting them, PN connection points are continuously provided. When a current is passed, heat is dissipated at the connection point where the current flows from the P-type semiconductor 7 to the N-type semiconductor 6, and heat absorption is performed at the connection point where the current flows from the N-type semiconductor 6 to the P-type semiconductor 7. That is, when a current is passed in the direction of arrow A in FIG. 16, heat is dissipated on the upper surface 5b and heat is absorbed on the lower surface 5a. When an electric current is applied in the opposite direction, heat is absorbed on the upper surface 5b and heat is dissipated on the lower surface 5a. By sequentially removing the heat generated from the heat radiation side, the heat absorption on the heat absorption side is promoted.

Since such a Peltier element 5 exerts a heat exchange function by electric energy, if it is used, for example, in an air conditioner of a vehicle running by an engine, electric power is supplied from a power source even when the engine is stopped. This makes it possible to air-condition the vehicle interior. Further, if the power source is a solar cell, it is suitable for an auxiliary air conditioner that suppresses the temperature rise in the passenger compartment when the vehicle is parked.
An example of such an auxiliary air conditioner is the actual open sho 58-1368.
15 are described.

The air conditioner described in the above publication is provided with a solar cell on the roof of a vehicle, a Peltier element provided in a blower duct which is a part of an existing air conditioner used while the vehicle is running, and the same. In addition, by supplying power to the blower, which is a part of the existing air conditioner, from the solar cells according to the temperature inside the vehicle and the temperature outside the vehicle, it is possible to blow out cool air into the vehicle. It is possible to cool the passenger compartment even when the engine is not running. Such a configuration
It is possible to improve the comfort when a passenger gets into a car parked in the hot sun, and because it is realized by simply adding a solar cell and a Peltier element to the existing air conditioner configuration,
It is considered to be cost effective.

Needless to say, the air conditioner as described above needs to be supplied with sufficient electric power from the solar cell. However, if the roof area of the vehicle cannot be made large due to vehicle design restrictions, the solar cell installed on the roof must be small, and the electric power from the solar cell becomes insufficient, so You may not be able to secure sufficient comfort immediately after boarding the car. Also, since the Peltier element is added to the existing air conditioner,
It may be installed in a portion that is not necessarily good in terms of cooling efficiency. Although such a problem can be solved by improving the cooling capacity of the Peltier device, it leads to an increase in size of the Peltier device and an increase in cost.

[0006]

a Peltier element unit 610 attached to each a
And each heat absorption surface 61 of the Peltier element unit 610.
0a is exposed inside the vehicle compartment, and each heat radiation surface 610b is exposed outside the vehicle compartment. A garnish 684 having a notch is attached to the vehicle exterior side of the sub air conditioning unit 683 to improve the appearance of the vehicle appearance and prevent the heat radiation surface 610b of the Peltier element unit 610 from being exposed to direct sunlight. Further, a trim 685 having a notch is also provided on the vehicle interior side of the sub air conditioning unit 683.

With the above configuration, if the occupant turns on the manual switch 23 when the vehicle is parked, the Peltier element unit 610 is powered by the solar cell 3.
Can be driven to cool the vehicle interior. In particular,
Since the heat radiation surface 610b of the Peltier element unit 610 faces directly outside the vehicle interior and the heat absorption surface 610a directly faces the vehicle interior, it is possible to improve both the heat radiation efficiency and the heat absorption efficiency of the Peltier element, and eventually the Peltier element. This will improve the cooling efficiency. Further, in this embodiment, since the Peltier element unit 610 is attached to the rear quarter window opening 680 which is the existing configuration, the number of dedicated parts is small, which is advantageous in terms of cost.

In each of the above-described embodiments, the heat absorption of the Peltier element is used for cooling the passenger compartment, but the controller 21 is also configured to control the direction of the electric current supplied to the Peltier element. It is possible to selectively cool and heat the passenger compartment while maintaining the configuration. At that time, the controller 21 may determine the necessity of cooling or heating based on the input vehicle interior temperature, and control the direction of the current supplied to the Peltier element.

Further, in each of the above-mentioned embodiments, the air conditioning of the interior of the parked vehicle is performed. However, if the air conditioning is performed even when the vehicle 1 traveling by the engine is congested. The air conditioning of the vehicle compartment can be performed without imposing a load on the battery 20. For example, the determination of the traffic jam state may be configured such that the duration of the idling state of the engine is input to the controller 21 and the controller 21 performs the determination based on the duration.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the invention. There is no limit.
