When the internal air conditioner provided in this application is specifically used, it needs to be controlled according to the following process:

In cooling mode:

The first control method: the air conditioner opens the lower air outlet (second air outlet 12) by default to let the air out, so that while the temperature in the environment (such as indoors or in the car, etc.) drops, the user can feel the cool breeze. (Or inside the car, etc.) when it drops to the set cooling temperature threshold, the temperature sensor of the air conditioner controls the air conditioner to automatically switch to the upper air outlet (first air outlet 11) for air outlet, and the lower air outlet (second air outlet 12) for air inlet to ensure that the cool air is not Will blow to users;

The second control method: the air conditioner defaults to the air outlet (second air outlet 12) when the air is turned on, so that while the room temperature drops, the user can feel the cool breeze. When the air conditioner runs to the time threshold (5 minutes or 10 minutes, etc.), The air conditioner is switched to the upper air outlet (the first air outlet 11) to discharge air to ensure that the cool breeze will not blow to the user.

In heating mode:

By default, the air conditioner first opens the lower air outlet (second air outlet 12) to let the air out, so that the temperature in the environment (such as indoor or car, etc.) rises. When it reaches the set heating temperature threshold, the air conditioner's temperature sensor controls the air conditioner to switch automatically The wind is discharged from the upper air outlet (the first air outlet 11), and the wind speed is controlled to decrease.
