The temperature information of the indoor air and the outdoor air may be received, respectively, and the two temperatures may be compared to determine whether to perform total heat exchange or bypass. If heat exchange is required between indoor air and outdoor air, select the total heat exchange mode. If heat exchange between indoor air and outdoor air is not required, select the bypass mode.

When the total heat exchange mode is selected, as shown in FIG. 3 , heat exchange is performed between indoor air and outdoor air while passing through the total heat exchanger 115 .

Therefore, it is possible to heat the outdoor air flowing into the room using the high-temperature indoor air or cool the outdoor air flowing into the room by using the low-temperature indoor air, thereby improving energy efficiency.

In addition, the outdoor air supplied to the room exchanges heat with the exhausted indoor air, so that the difference between the indoor temperature and the outdoor air is not large. Therefore, it is possible to create a comfortable indoor environment because outdoor air with a small temperature difference is introduced.

When the bypass mode is selected, as shown in FIG. 4 , outdoor air flows into the room through the total heat exchanger 115 , and the indoor air passes through the bypass flow path 119 without going through the total heat exchanger 115 . exhausted to the outside Therefore, indoor cooling or heating is possible by using the temperature of the outdoor air.

On the other hand, when controlling in the ventilation mode, the air supply amount of the outdoor air supplied to the room by the air supply blower 117 and the exhaust amount of the indoor air exhausted to the outdoors by the exhaust blower 118 are different. can

The air supply and exhaust amount may be adjusted by adjusting the opening degree of dampers provided in the ducts 105, 106, 107, and 108, and the rotation speed of the air supply blower 117 and the rotation speed of the exhaust blower 118 are different from each other. You can also make it adjustable.

When exhaust is made by the exhaust device 10 , it is preferable to form a kitchen near the exhaust device 10 at a low negative pressure in order to ensure smooth exhaust through the exhaust device 10 . In addition, by maintaining a higher pressure than the weak negative pressure of the kitchen in the living room, it is possible to prevent the indoor diffusion of polluted air.

In the air conditioner 100, the indoor pressure can be set to a desired pressure by adjusting the air supply amount and the exhaust amount, thereby preventing smooth exhaust and diffusion of polluted air.
