FIG. 3 is a schematic view showing a main part of a floor in the building 1 when viewed from above. FIG. 3 shows the living room 2 and the passage 3 also shown in FIG. A plurality of indoor units 4a to 4h are attached to the ceiling of the living room 2. Further, a plurality of indoor units 4i to 4k are also attached to the passage 3. The contents common to the indoor units 4a to 4k are collectively referred to as "indoor unit 4". The living room 2 is provided with two entrances 6a and 6b. It should be noted that what is common to the doorways 6a and 6b is collectively referred to as "doorway 6". The number and position of the entrance 6 is an example, and it is not necessary to limit the number and position to this example. Further, one emergency exit 7 is shown in the passage 3.

Next, the operation in the present embodiment will be described.

During normal operation of air conditioning, the air conditioning control unit 11 controls on / off of the indoor units 4a to 4h according to the user operation of the remote controller installed in the living room 2, and operates at the set temperature, wind direction, and air volume when the indoor units 4a to 4h are in the ON state. Control the air conditioning so that it does. Further, predetermined operation control is performed for the indoor units 4i to 4k in the passage 3.

Here, it is assumed that a fire breaks out in the building 1. In this case, a fire monitoring device (not shown) transmits a fire detection signal to the air conditioning control device 10. Upon receiving the fire detection signal, the air conditioning control unit 11 reads the control information from the fire mode information storage unit 12 and controls the operation of the indoor unit 4 in the fire mode according to the read control information. In the control information, the on / off state and the wind direction and the air volume for the indoor unit 4 to be turned on are set for each indoor unit 4. In particular, for the indoor unit 4 in which the blowout from each outlet can be individually controlled, on / off, air volume and wind direction are set for each outlet.

As illustrated in FIG. 3, when the living room 2 is provided with two entrances 6a and 6b, the employees and the like in the living room 2 can move from their respective locations as shown by the arrows 8a and 8b shown by the broken lines. They will move toward the closer doorways 6a and 6b, exit from room 2 and evacuate. Therefore, the air conditioning control unit 11 controls the operation of each indoor unit 4 so as to blow out air as shown by the solid arrow 9a associated with the indoor unit 4a according to the setting contents of the control information. That is, as is clear from FIG. 3, the air conditioning control unit 11 evacuates the smoke generated from the fire source and entering the living room 2 (smoke generated in the living room 2 when the fire source is the living room 2) in the living room 2. The indoor units 4a to 4h are operated in cooperation with each other so as to be away from the paths 8a and 8b. Specifically, the indoor units 4a and 4b exhaust the intake air in the living room 2 in the direction away from the evacuation route 8a (upward in the drawing) to exhaust the smoke in the vicinity of the indoor units 4a and 4b to the end of the living room 2 (the end of the living room 2 (). Drive up to the drawing). Further, the air conditioning control unit 11 may blow out air so as to keep smoke away from the entrance / exit 6a as shown by the arrow 9b. An air outlet whose arrow is not shown means that the operation is stopped.

Similarly, the indoor units 4g and 4h are blown away from the evacuation route 8a (downward in the drawing) to drive smoke near the indoor units 4g and 4h to the end of the living room 2 (downward in the drawing).

The operation of the indoor units 4c to 4f is basically controlled in the same manner as described above. However, the arrow 9c is shown relatively shorter than the arrow 9d. This indicates that the air volume was kept low, but the air volume may be adjusted as in this example. Even if the exhaust gas indicated by the arrow 9d from the indoor unit 4e enters the evacuation route 8a, the indoor unit 4a or the like will eventually drive the exhaust gas to the end of the living room 2. In this way, it is preferable to adjust the air volume and the vertical direction of the blown air so that the evacuation routes 8a and 8b can be easily secured.

The same can be said for the control of the indoor unit 4 in the living room 2 described above in the passage 3. That is, when an employee or the like who has left the living room 2 evacuates from the emergency exit 7 according to a predetermined evacuation route, the operation of the indoor units 4i to 4k is controlled so as to keep smoke away from the emergency exit 7. The indoor unit 4j sends smoke in the direction of the doorway 6a, but the smoke sent in the direction of the doorway 6a is driven by the indoor unit 4i from the doorway 6a to the end of the passage 3 (upward in the drawing). Become.

As described above, according to the present embodiment, the smoke generated from the fire source can be kept away from the evacuation route by operating the indoor unit 4 in cooperation with each other.

When the air conditioning control unit 11 in the present embodiment receives the fire occurrence location information together with the fire detection signal (step 101), the air conditioning control unit 11 acquires each information registered in the position information storage unit 13 and the route information storage unit 14. (Step 102). Then, the air conditioning control unit 11 compares the fire occurrence location with the evacuation route candidates read from the route information storage unit 14, and determines the evacuation route of the person in the building 1 (step 103). Basically, the shortest evacuation route that can quickly leave the outdoors is selected with reference to the number of people evacuating, etc., but the air conditioning control unit 11 passes the evacuation route at or near the place where the fire broke out. If you do, you will have to select a detour route.

When the evacuation route is determined, the air conditioning control unit 11 cooperates with the indoor unit 4 so as to keep the smoke generated from the fire source away from the evacuation route (step 104). Specifically, as illustrated in the first embodiment, on / off control of the operation of each air outlet of each indoor unit 4, and when it is on, the wind direction and air volume are controlled.

As described above, according to the present embodiment, an evacuation route is determined with reference to the fire occurrence location, and the indoor unit 4 is operated in cooperation with each other so as to keep smoke away from the determined evacuation route.

In addition to the above-mentioned air-conditioning control, for example, in the room where the fire occurred, the air-conditioning control is performed so that the smoke does not diffuse from the fire source, or when it is confirmed that the window is open, the smoke is emitted from the building 1. It is preferable that the air conditioner is controlled so as to exhaust the air to the outside of the building, or the air conditioner control unit 11 performs appropriate air conditioner control according to the environment, the situation, and the like of the building 1.
