Air conditioning is performed by distributing it to the air conditioning section.

るという問題がある。For this reason, heat is not necessarily distributed appropriately to the air-conditioned area. In other words, when there are air-conditioned parts with a difference between the room temperature and the set temperature of 1°C, 2°C, and 4°C, respectively, the air conditioner body receives heat equivalent to the total temperature difference from each air-conditioned part. Since a load request is issued, the air conditioner itself operates accordingly. Therefore, since the damper opening degree of the air-conditioned area is automatically determined based on the difference between the room temperature of the air-conditioned area and the set temperature, the damper opening degree of the air-conditioned area of each of the three rooms is 1 to 2 pairs. The ratio is not 4. In addition, in the case of the above example, it would be better if the damper opening degree of the air-conditioned part at 4°C was fixed at 100% until the temperature difference in the air-conditioned part was resolved. It goes without saying. In the conventional distributed processing method for each air-conditioned part, the damper is closed each time the temperature difference between the air-conditioned parts decreases. It is common for the damper opening of some parts to fall below 100% and the damper opening to be controlled at less than 100%. In addition, in the case of room operation, in the conventional method of opening and closing the damper opening depending on the temperature difference between the air conditioned parts, the damper opening closes each time the temperature difference is eliminated, and the air conditioner body However, due to the decrease in the capacity of the air conditioner itself, the speed at which the temperature difference in the air-conditioned parts is resolved decreases, so the damper opening degree opens. As the damper opens, more air conditioning is performed on the air-conditioned area, and the temperature difference decreases again. This time, the damper closes in accordance with the extent to which the temperature difference is eliminated. A characteristic of conventional distributed processing systems is that the damper frequently opens and closes to control the temperature of the air conditioned area, and at the same time, the air conditioner itself also increases or decreases its capacity according to the damper opening. At the same time, air conditioning was being carried out in the air-conditioned areas. For this reason, there is a problem in that the opening and closing of the damper is not in harmony with the air conditioner main body, and the damper is opened and closed so frequently that the damper sound becomes harsh, reducing the reliability of the damper.

sequentially transmits VAV information, which is control information for each damper opening adjustment mechanism 9, so this information is received (step 130). It is determined whether this received information is the setting address of each damper opening adjustment machine 19 (step 140), and if it is the setting address, the main controller 8
The storage device provided in [Step 1 to save to RAM]
50), the process is repeated until the information from all damper opening adjustment mechanisms 9 has been received (step 160). If information from all damper opening adjustment mechanisms 9 has been received, the operation mode of the main controller 8 is determined in step 17.
0), determine and command the amount of air blown by the indoor unit 2 for air conditioning (step 180), command the indoor unit 2 to determine cold air/warm air and its degree i (step 190);
Broadcast the information of indoor unit 2 by indoor unit information processing (
Step 200).

行う（ステップ２５０）。FIG. 6 is a detailed flowchart showing the indoor unit information processing at step 200 in FIG. In the indoor unit information processing shown in FIG. 6, the reception signal from each damper opening adjustment mechanism 9 is determined (step 210), and it is determined whether the damper opening adjustment mechanism 9 has the maximum load (step 220).
). In the case of the maximum load damper opening adjustment mechanism 9,
Set the damper fixed opening command (Step 230), and if the damper opening adjustment mechanism 9 is not at the maximum load, set the damper free opening command (Step 240), and adjust the damper opening in conjunction with other indoor unit information. Broadcast transmission is performed to mechanism 9 (step 250).

室外機制御が行えるようにしている。In FIG. 7, when power is applied to the damper opening adjustment mechanism 9 (step 310), it waits for information from the indoor unit 2 to be received (step 320), and then the room temperature is determined from the remote control 10 attached to the air conditioned part. (step 330), and further receives the set temperature from the remote controller 10 (step 34).
0). Then, the damper opening degree is determined from the difference between the received room temperature and the set temperature (step 350). It is determined whether a damper fixed opening command is issued based on the indoor unit information (step 360). If the damper fixed opening command has been issued, the damper is fixed fully open for damper fixed opening control (step 370). If the damper fixed opening command has not been issued, damper free opening control is performed (step 380). Then step 32
After receiving the indoor unit information at step 0, the main controller 8 waits for the damper opening adjustment mechanism information transmission order (step 390), transmits the information of the damper opening adjustment mechanism 9, and the main controller 8 sends the damper opening adjustment mechanism information to each damper opening adjustment mechanism 9. Optimal air blow control by obtaining information on

。In the step 360, if there is no damper fixed opening command, each damper opening adjustment mechanism 9 performs only distributed processing, and optimal air conditioning control is achieved by combining with other damper opening adjustment mechanisms 9. can't do it. Conventionally, no opening command means was considered in the main controller 8, so it was possible to integrate the ventilation control and outdoor unit control of the main controller 8 with the damper opening control by each damper opening adjustment mechanism 9. The experimental results show that the damper of the air-conditioned part that requires the most load is not necessarily at 100%, but is constantly opening and closing at 100% and below 100%. As it has become clear, each damper opening adjustment mechanism 1ll9 is integrated with the main controller 8 through distributed processing control, so that the damper opening of any one of the opening adjustment mechanisms is adjusted to 1.
00%, various control methods have been considered in order to effectively condition the air in the air-conditioned part of the damper opening adjustment mechanism 9 that requires the most load, but distributed processing control has been mainly considered. In the control described above, it is difficult to integrate the main controller 8 and each damper opening adjustment mechanism 9. However, by introducing a damper fixed opening command from the main controller 8 into distributed processing control and incorporating a partially centralized control mode, the control of the main controller 8 can be adjusted without becoming too complicated. Optimal damper opening control that integrates with the mechanism 9 has been realized, and since the damper is fixed, frequent opening and closing operations are eliminated, damper wear is reduced, and damper opening/closing noise is reduced and failures occur. It is possible to improve reliability by reducing the rate.
