(Operation) Therefore, if the rotational speeds of the blowers 10a and 10b are individually adjusted to the left and right, even if the position of the air distribution door 24 is uniquely determined according to each mode, the total amount of air flowing through the air passages 3a and 3b is reduced. Since the air volume changes, the left and right temperature states of the air distribution chambers 17a and 17b can be widely varied. In addition to this, by independently operating the bypass doors to adjust the amount of air passing through the bypass passages 16a and 16b, the temperature of the air sent to the upper side of the air distribution windows 17a and 17b can be independently set up and down for each of the air passages 3a and 3b. Then, the temperature can be adjusted. Therefore, except the bypass doors 18a and 18b and the blowers 10a and 10b, the left and right air passages 3a and 3b are provided.
However, the above-mentioned problems can be achieved because the air conditioning control can be separately performed for the left and right sides and the upper and lower sides of the vehicle interior.

The differential door 22, the vent door 23, and the air distribution door 24 are arranged via the partition plate 2, and both air passages 3a, 3 are provided.
It is common in b. In particular, as shown in FIG. 3, the air distribution door 24 is of a type in which the parts arranged in the respective air passages 3a and 3b are provided coaxially and move in the same manner, and is arranged behind the heat exchanger for heating. Heat exchanger 1 for heating
3 is contacted with a guide piece 25 extending from the upper end of the air distribution chamber 1
The air distribution chambers 17a and 17b are separated by a first stationary position that divides the upper and lower parts 7a and 17b from each other and the substantially center of the heat exchanger for heating.
a second stationary position that divides b into upper and lower portions and a guide piece 26 that extends from the lower portion of the case 1 to be in contact with the foot outlet 21.

First, in the vent mode, open the vent door 23,
The differential door 22 is closed and the ventilation door 24 is placed in the third rest position. For example, if the right side of the vehicle is to be MAX vented and the left side is to be in the temperature control mode, the right side bypass door 18a may be fully opened and the left side bypass door 18b may be closed. As a result, on the right side, the air that has passed through the heat exchanger 12 for cooling receives the heat exchanger 13 for heating and the bypass passage 18a.
And then all of the air is delivered to the upper outlet 20. On the other hand, on the left side, all the air that has passed through the cooling heat exchanger 12 enters the heating heat exchanger 13 in which the heating medium has flowed, and the heating heat exchanger 13 adjusts the temperature as appropriate and then the upper part. It is sent to the outlets 20a and 20b.

In the bi-level mode, the vent door 23 is opened and the differential door 22 is closed. In the cold air mode, the bypass doors 18a and 18b are opened, and the air distribution door 24 is set to the first stationary position. In the same temperature mode, the air distribution door 24 may be set to the second stationary position and the bypass doors 18a and 18b may be set to arbitrary positions. As a result, in the cold air mode, all the air that has passed through the heating heat exchanger 13 in which the heat medium has flowed is sent to the foot outlets 21a and 21b, and the amount of cool air sent to the upper outlet 20 is the bypass passages 16a and 16b. It is determined by the opening degree of. That is, the temperature difference between the upper and lower sides can be made large in the cold air mode. On the other hand, in the same temperature mode, the air that has passed through the heat exchanger 13 for heating in which the heat medium has flown is distributed by the air distribution door 24, and about half of the air is guided downward by the air distribution door 24 and the foot outlet 21a, 2
Sent to 1b. About the other half is the air distribution chambers 17a, 17b
Is mixed with the air that has passed through the bypass passages 16a and 16b according to the positions of the bypass doors 18a and 18b, and is sent to the upper outlets 20a and 20b together.
Therefore, in each of the air passages 3a and 3b, the air sent to the upper side of the air distribution chambers 17a and 17b is the air distribution door 2
Bypass doors 18a, 18b even if the position of 4 is the same
The temperature can be adjusted by controlling the opening degree of. That is, in the same temperature mode, there is no difference between the upper and lower temperatures, or the difference can be reduced. If the rotational speeds of the blowers 10a and 10b are controlled separately, the left and right temperature control is controlled while affecting the upper and lower temperatures.

In the differential heat mode, the differential door 22 is opened, the vent door 23 is closed, and the air distribution door 24 is in the second stationary position. Bypass doors 18a, 18b in this case
May be set at any position. Then, the air heated by the heating heat exchanger 13 in which the heating medium is flowed is distributed by the air distribution door 2
4, the air is sent to the defrost outlets 19 and the foot outlets 21a and 21b approximately half by half, and the air passing through the bypass passages 16a and 16b is further sent to the defrost outlets 19 according to the positions of the bypass doors 18a and 18b. Therefore, even in this mode, the bypass door 18a,
By controlling 18b, the temperature of the air sent to the defrost outlet 19 can be adjusted, and by controlling the number of revolutions of the blowers 10a, 10b, the temperature of the air sent to the foot outlets 21a, 21b can be adjusted.

In the defrost mode, the bypass doors 18a, 1
8b and the vent door 23 are closed, the air distribution door 24 is set to the third stationary position, and the differential door 22 is opened. As a result, all the air that has passed through the heat exchanger 12 for cooling enters the heat exchanger 13 for heating in which the heat medium has flowed, where the temperature is adjusted appropriately and then sent to the defrost outlet 19. Also in this case, as in the heater mode, by adjusting the left and right rotation speeds of the blowers 10a and 10b separately, the temperature of the air blown out through the defrost outlet 19 can be individually controlled.

In the present embodiment, the case where the differential door 22 and the vent door 23 are separately arranged is shown. However, even if the defrost outlet 19 and the upper outlets 20a and 20b are switched by one door, the same operational effect can be obtained. Is what you get.

(Effects of the Invention) As described above, according to the present invention, even if the components other than the bypass door and the blower are common to the left and right air passages,
Depending on the opening of the bypass door and the rotation speed of the blower, the temperature of the air flowing upward in the air distribution chamber and the temperature of the air flowing downward can be adjusted separately for each air passage. The temperature can be controlled independently. Further, since the components other than the bypass door and the blower are common to the left and right air passages, the structure can be simplified and the cost can be reduced.
