It may be connected via.

FIG. 9 is a flowchart showing an example of the operation of a conventional rotation control. The operation of the conventional air conditioning rotation control system will be described below with reference to FIGS. Now, the contents of the program data 91e are such that the rotation time interval is 5 minutes, the control contents in the rotation state are stopped, the rotation release state is the original state, and the rotation switching destination is:
The case where the air conditioner 92 is set to the air conditioner 93 and the air conditioner 93 is set to the air conditioner 92 will be described. Furthermore, before the start of the rotation control, the air conditioner 9
2 and the air conditioner 93 are both operating.

In order to start the rotation control of the air conditioning equipment, when a rotation control start operation is performed on the operation unit 91a of the air conditioning system management unit 91, a rotation start command is transmitted to the management unit control means 91b ( Step 1). When receiving the rotation control start command, the management unit control unit 91b receives the rotation control start command.
Of the rotation control data 91f stored in the management unit storage unit 91d, and then creates a command content for transmission to the air conditioner. In this case, a stop command is issued by a command to change the air conditioner 92 to the rotation state (step 2). A stop command, which is a command to change the air conditioner 92 into a rotation state, created by the rotation control program 91e, is transmitted to the air conditioner 92 via the management unit communication unit 91c and the communication unit 92a. The air conditioner 92 that has received the stop command that is the command to change to the rotation state enters the rotation state according to the command and stops. At this time, the state before the rotation state is stored in the air conditioning system management unit 91 so that the air conditioner 92 can be returned to the original state when the rotation control is released again. In this case, the fact that the air conditioner 92 was in the operating state is stored (step 3). When five minutes, which is the rotation interval time, has elapsed since the air conditioning system management unit 91 transmitted the rotation state command to the air conditioning equipment 92, the management unit control unit 91b of the air conditioning system management unit 91 sets the rotation control program 91e.
With reference to the contents of the above, the contents of a command to be transmitted to the air conditioners 92 and 93 for switching the rotation are created. In this case, the operation command is a change command to change the rotation of the air conditioner 92 to the original state, and the stop command is a change command to the air conditioner 93 to change to the rotation state (step 4). The operation command to the air conditioner 92 created by the control program 91e is transmitted to the air conditioner 92 via the management unit communication unit 91c and the communication unit 92a. The air conditioner 92 that has received the operation command that is the command to change to the rotation release state enters the rotation release state and starts operation. The stop command, which is a command to change the air conditioner 93 to the rotation state, is transmitted to the air conditioner 93 via the management unit communication unit 91c and the communication unit 93a.
Sent to. The air conditioner 93 that has received the stop command that is the command to change to the rotation state is stopped. At this time, the state before the rotation state is stored in the air conditioning system management unit 91 so that the air conditioner 93 can be returned to the original state when the rotation control is released again (step 5). When 5 minutes, which is the rotation interval, has elapsed since the air conditioning system management unit 91 transmitted the rotation state command to the air conditioning equipment 93, the management unit control unit 91b of the air conditioning system management unit 91 refers to the contents of the rotation control program 91e. Then, a command content to be transmitted to the air conditioners 92 and 93 for switching the rotation is created. In this case, the operation command is a command to change the air conditioner 93 to the rotation release state for returning the air conditioner 93 to the original state, and the stop command is a command to change the air conditioner 92 to the rotation state (step 6). The operation command to the air conditioner 93 created by the control program 91e is transmitted to the air conditioner 93 via the management unit communication unit 91c and the communication unit 93a. The air conditioner 93 that has received the operation command that is the command to change to the rotation release state enters the rotation release state and starts operating. A stop command, which is a command to change the air conditioner 92 to the rotation state, is transmitted to the air conditioner 92 via the management unit communication unit 91c and the communication unit 92a. The air conditioner 92 that has received the stop command that is the command to change to the rotation state is stopped. At this time, the state before the rotation state is stored in the air conditioning system management unit 91 so that the air conditioner 92 can be returned to the original state when the rotation control is released again (step 7). Hereinafter, for each set rotation interval time (step 4) to (step 7)
Is repeatedly executed to perform rotation control (step 8). To end the rotation control, when a rotation control end operation is performed on the operation unit 1a of the air conditioning system management unit 91, a rotation end command is transmitted to the management unit control unit 91b. Upon receiving the rotation control end command, the management unit control unit 91b executes the rotation control program 91e stored in the management unit storage unit 91d, and creates a command content for transmission to the air conditioner. In this case, the operation command is a rotation cancellation state command for returning the air conditioner 93 to the original state before the rotation control. An operation command, which is a rotation release state command to the air conditioner 93 created by the rotation control program 91e, is transmitted to the air conditioner 93 via the management unit communication unit 91c and the communication unit 93a. The air conditioner 93 that has received the operation command starts operation according to the command (step 9).

At this time, the air conditioning system management unit stores that the air conditioner 93 was in the rotation state at the end of the current rotation control, and the control from the air conditioner 93 is started from the rotation state at the start of the next rotation control. I do. This is because, when the rotation control is started, the air conditioners that are initially in the rotation state are averaged so as not to be continuously the same device.
