Then, 11 is a microcomputer mainly composed of a central processing unit CPU (hereinafter, abbreviated as "microcomputer"), 12 is a non-volatile memory (an example of a storage means), 13 is a communication circuit of the outdoor unit 1, and 13A.

It is a setting input circuit for. Each control device 1A, 2A, 3A is preset with an address having a value that does not overlap with other control devices and stored in the non-volatile memory 12, and that unit of the outdoor unit 1, the indoor unit 2, and the remote controller 3 is stored. Attribute information for specifying which type of unit is also set in advance and stored in the non-volatile memory 12.

Generally, in the air conditioning system, the indoor unit 2 receives the setting data such as the operation start / stop and the target indoor temperature set and input from the remote controller 3, and the operating conditions for the indoor environment are changed. Therefore, the indoor unit 2 is the outdoor unit 1
The communication is performed, and the operation is performed by receiving the supply of the refrigerant according to the changed operating condition. Further, in the air conditioning system, the outdoor unit 1 to the indoor unit 2 are connected by a refrigerant pipe 6 so that the refrigerant can flow, or the central control remote controller 4 to the outdoor unit 1 to the indoor unit 2 to the remote controller 3 are connected to the transmission line 5B, It goes without saying that a physical connection such as a communicable connection by 5A is required, and in order to make the functions of a plurality of units organically and efficiently, for example, one unit and another unit ( The connection relation information indicating whether the connection is established via the refrigerant pipe 6 or the transmission lines 5B, 5A) is pre-calculated prior to the operation and stored in the non-volatile memory 12 of the outdoor unit 1, and the physical information is stored in the outdoor unit 1. It is necessary to set the information for the indoor unit 2 and the remote controller 3 that are physically connected.

As the connection relation information, in this air conditioning system, the outdoor units 1 to 1 connected via the refrigerant pipe 6 are connected.
Refrigerant system connection relation information between the indoor units 2 (an example of refrigerant pipe connection relation information) and operation system connection relation information (communication connection relation information) for communication such as control signals connected via the transmission lines 5B and 5A. Is set) and are set. In this air conditioning system, one or more indoor units 2 and a remote controller 4 around one outdoor unit 1 are connected via a refrigerant pipe 6 and a transmission line 5A to form one basic system. The system constitutes the entire air conditioning system. Even if the outdoor unit 1 of a certain basic system does not communicate with another basic system, the controller 1A calculates, stores, and sets the refrigerant system connection relation information and the operation system connection relation information in the basic system. Alternatively, it is possible to perform the air conditioning operation based on each connection relation information and the operation condition. However, the air conditioning system as a whole may be operated in conjunction with other basic systems.
In such a case, communication is performed between the plurality of basic systems via the transmission line 5B and the central control remote controller 4.

However, when calculating, storing, and setting the connection relation information in a certain basic system, if this basic system and another basic system are communicatively connected by a transmission line 5B, the other basic system Unwanted signals may be communicated. In this case, since the serial communication system is adopted between the basic systems as described above, it is impossible to simultaneously communicate two or more signals in parallel. Therefore, communication may be congested between the basic systems, and calculation, storage, and setting of connection relation information in each basic system will be delayed. In order to avoid such an inconvenience, the controller 1A of each outdoor unit 1 is provided with the switch circuit 14 for connecting / disconnecting the transmission line 5B used for communication with another basic system from / to the communication circuit 13. It is being done. As a result, the switch circuit 14 is held in an open state so that signals do not flow to another basic system until the calculation, storage, and setting of the connection relation information in its own basic system are completed, and after completion, the switch circuit 14 is completed. It is configured to connect.

Subsequently, the conventional outdoor unit 1 of the air conditioning system calculates connection-related information in the basic system.
The operation of storing / setting will be described. FIG. 7 is a flowchart showing a processing procedure for calculating / storing / setting the connection relation information in the basic system by the control device of the outdoor unit of the conventional air conditioning system. First, the control device 1 of the outdoor unit 1
The microcomputer 11 of A does not communicate with other basic systems until the calculation, storage, and setting of the connection relation information within its own basic system are completed.
Is kept open (step 27A). Next, in order to search for a unit connected to the outdoor unit 1 via the refrigerant pipe 6 or the transmission line 5A in its own basic system, an initial value of the address of the unit to be searched is set (step 27B). Then, a connection-related search signal is transmitted to the unit in which the address of that value is stored (step 27C).

Then, it is judged whether or not there is a response from the unit having the address of the search destination to this search signal (step 27D), and if there is no response, the value of the address is set to 1
Proceed (step 27K) and return to step 27C. If it is determined in step 27D that there is a response, the attribute information is extracted from the value of the address and the communication data and stored in the non-volatile memory 12 (step 27E). After that, the value of the address is advanced by 1 (step 27F), and it is judged whether or not the value of the address exceeds the maximum address value for performing search communication (step 27G). If not, the process returns to step 27C. If it is determined in step 27G that the maximum address value has been reached, the unit search is ended, and the refrigerant related to the refrigerant cycle is used as information indicating the connection relationship between the units based on the address and attribute information of the unit that responded. System connection relation information and operation system connection relation information for setting and controlling operating conditions are calculated and stored in the nonvolatile memory 12 (step 27H). Then, communication is performed with respect to the units that have responded, that is, the units that have some connection relationship, and the connection relationship information is set in these units (step 27I). When the above process is completed, the switch circuit 14 is connected to make the transmission line 5A and the transmission line 5B communicable (step 27J).

Hereinafter, for other basic systems as well, the control unit 1A of the outdoor unit 1 belonging to the basic system calculates, stores and sets the connection relation information in the basic system. Further, by the control device 4A of the centralized control remote controller 4, for each unit in all the basic systems, only the operation system connection relation information is recalculated in the same manner as the processing procedure of FIG. After being stored in, the unit is set again for the unit determined to have some connection relationship. Therefore, the microcomputer 11 (an example of control means) of the control device 1 is based on the refrigerant system connection relation information and the operation system connection relation information stored in the non-volatile memory 12 and the indoor air condition set and input from the remote controller 3. , Drive control of the indoor unit 2 and the outdoor unit 1.

[0010]

As described above, in the conventional air conditioning system, both the refrigerant system connection relation information and the operation system connection relation information of the units in each basic system are controlled by the control device 1A of each outdoor unit 1. Despite the calculation, storage, and setting of the above, the operation system connection relation information is then calculated, stored, and set again from the central control remote controller 4 for each unit of all basic systems. Was there. Therefore, there is a problem that it takes a long time to complete the calculation, storage, and setting of the refrigerant system connection relation information and the operation system connection relation information, and the startup time until the start of the air conditioning operation becomes long.

Further, when it is necessary to replace these control boards with new ones due to, for example, a failure of a control board which constitutes each of the control apparatus 1A, the control apparatus 2A, or the control apparatus 3A, or the transmission line 5A is replaced. Via remote control 3
You may want to change the connection destination of. Further, the connection relationship between the outdoor unit 1 and the indoor unit 2 via the refrigerant pipe 6 is rarely changed. In these cases, operation system connection relationship information between the replaced new control board and another control board connected thereto via the transmission line 5A, operation system connection relationship information of the remote controller 3 whose connection destination is changed, Alternatively, the refrigerant system connection relation information relating to the change of the connection destination of the refrigerant pipe 6 may be partially changed or may be changed. Such partial update / change processing of the operation system connection relation information or the refrigerant system connection relation information has been manually performed one by one. These partial update / change operations are extremely cumbersome operations because it is necessary to search for and execute update / change portions from a large amount of information data. In addition, there is a possibility of making a mistake in setting the wrong information, and there is room for improvement in terms of after-sales service.

The present invention has been made in order to solve the above-mentioned problems, and is a processing operation for calculating, storing, and setting the refrigerant system connection relation information and the operation system connection relation information necessary at the start of operation. The present invention provides an air conditioning system capable of quickly completing the calculation, storage, and setting of each connection-related information by rationally executing.

Further, even if it is necessary to update / change the refrigerant system connection relation information and the operation system connection relation information, it is possible to deal with them easily and surely, and an air conditioning system having excellent serviceability is provided. To do.

FIG. 2 is a flow chart showing a processing procedure of an operation program for calculating / storing / setting the connection relation information in the basic system by the controller of the outdoor unit of the air conditioning system according to the first embodiment of the present invention. Incidentally, the steps having the same processing contents as the steps of the flowchart showing the conventional processing procedure shown in FIG. 7 are designated by the same reference numerals. Here, the configuration including the communication circuit 13 of each unit and the transmission line 5A is an example of the first data communication unit, and the communication circuit 13 of the centralized control remote controller 4,
The configuration including the communication circuit 13 of the outdoor unit 1 and the transmission line 5B is an example of the second data communication unit. First, the microcomputer 11 of the control device 1A of the outdoor unit 1 completes the calculation, storage, and setting of the connection relationship information within its own basic system.
The switch circuit 14 is held in an open state so as not to communicate with another basic system (step 27A).

All of the refrigerant system connection relation information and the operation system connection relation information are erased from the nonvolatile memory 12. Only the refrigerant system connection relation information is erased from the non-volatile memory 12. If the determination at step 27Gc is YES, the unit that responds is communicated with the erase command signal of both the refrigerant system connection relation information and the operation system connection relation information (step 27Ge). In the case of the contents of the above, based on the address and attribute information of the responding unit, a delete command signal of only the refrigerant system connection relation information is communicated to the unit relating to the refrigerant system connection relation information (step 27G).
f). That is, steps 27Aa, 27Ga, 27Gc,

Only the relevant information is erased, and the contents of the non-volatile memory 12 are made blank. After that, the new refrigerant system connection relation information and the new operation system connection relation information are automatically calculated and set by the control device 1B of the outdoor unit 1 and the control device 4A of the centralized control remote controller 4. Therefore, even when it is necessary to change the refrigerant system connection relation information or the operation system connection relation information, for example, when the control board is replaced, the change process can be easily and accurately performed without human intervention. be able to. However, according to the second embodiment, when only one of the connection relationship information is erased, only the refrigerant system connection relationship information is erased. However, the invention is not limited to this, and only the operation system connection relationship information is erased. It goes without saying that it is also applicable to the case.
