Where is the air inlet of Honda Accord 6th generation air conditioner?

Before opening the air inlet of the Honda Accord 6th generation air conditioner, there is a plastic cover plate along the lower edge of the front windshield, and there are many small holes at one end of the cover plate, which is the air inlet.

The air inlet of a car should only be the air inlet and air outlet of the car engine. The air source of the engine is the atmosphere, which enters the air filter through the air inlet at the front end of the car (it is common in cars, and now the advanced car may be hidden), then enters the cylinder, and then enters through the air inlet of the cylinder.
