The opening and closing may be controlled by software.
Further, in the embodiment described above, the opening/closing of the ceiling window 3 is controlled by considering both the temperature and humidity inside the vehicle compartment 4, but instead of this, the opening/closing of the ceiling window 3 is controlled based only on either the temperature or the humidity. Opening and closing may be controlled. According to the present invention, in accordance with the outputs of the temperature sensor 7 and the humidity sensor 8, the air conditioner 30 is operated at the same time as the ceiling window 3 is closed so that the temperature and humidity become comfortable. 3 can be fully opened, the ceiling window 3 can be half-opened, or the ceiling window 3 can be closed. The interior of the vehicle compartment 4 can be air-conditioned very finely and with high precision by automatically switching between four ways: intake of outside air by the air, heat retention and humidity maintenance of the vehicle interior 4 by closing the ceiling window 3. Moreover, since the air conditioner 30 is activated at the same time as the ceiling window 3 is closed, there is no risk of the air cooled by the operation of the air conditioner 30 flowing out to the outside, and the interior of the vehicle compartment 4 can be cooled by taking in outside air. If there is enough, turn on cooling device 3.
Since the operation of the air conditioner 0 can be automatically stopped and the ceiling window 3 can be fully opened, unnecessary operation of the air conditioner 30 is eliminated, and air conditioning can be performed very efficiently, and its practical effects are significant. .
