Is mounted with a data structure called "object" of the indoor unit to be controlled, based on the standard for building management system communication. This "object" has a plurality of "properties" as data imitation elements based on the standard, and consists of an object identification number and an object name. Further, in the air conditioning communication device 4, the PAC address and the object identification number are mapped so as to correspond one-to-one, and the writing / reading for the object designated by the object identification number from the building management host 1 side is mapped thereto. Software for transmitting / receiving an air conditioning control command corresponding to writing / reading to / from the indoor unit having the PAC address via the air conditioning control network is installed.

Next, the address setting operation will be described step by step with reference to FIGS. In the following description, it is assumed that only two indoor units P1 and P2 are connected to the air conditioning communication device 4, the indoor unit P1 is installed in the A conference room, and the indoor unit P2 is installed in the B conference room. It will be described as being installed. First, an operator of a company in charge of an air conditioner operates an address setting switch (not shown) provided in the indoor unit P1 to set a PAC address. Here, the PAC address of the indoor unit P1 is assumed to be "PAC_1". The address value to be set at this time does not need to be decided in advance, and may be set independently for the convenience of the operator in charge of the air conditioner. Then, the operator P of the indoor unit P2
Set the AC address. The address value set at this time may be any value as long as at least the indoor unit under the air conditioning communication device 4 can be uniquely specified. Here, the PAC address of the indoor unit P2 is “PAC_2”. The PAC address setting work by the address setting switch may be carried out at the time of factory shipment of the packaged air conditioner.

Next, the worker goes out to the A conference room and operates the key switch 21 of the remote controller R1 to input the installation place name (in this example, "A conference room"). The key input analysis unit 22 determines whether the input key is an input operation of the installation place name or an operation operation, and when the input operation is the input operation of the installation place name, each key of the key switch 21 is pressed. The kana data assigned to the control unit 23 is sent to the control unit 23. In response to this, the control unit 23 transfers this kana-data to the kana-kanji conversion unit 24 and performs kana-kanji conversion processing. Then, the control unit 23 holds the character string subjected to the Kana-Kanji conversion inside and sends it to the display unit 25. In response to this, the display unit 25 converts it into display data and outputs it to the display unit 26.
As a result, the name of the installation location (in this example, "A conference room") is displayed on the display 26. The operator refers to this display content and confirms whether the input content is correct or not.

Subsequently, if the input content is correct, the operator inputs the character string input by pressing a predetermined key switch 21. In response to this, the key input analysis unit 22 notifies the control unit 23 that the confirmation operation has been performed. In response to this, the control unit 23 transmits the input character string (installation place name) to the indoor unit P1 via the communication unit 27. This character string data is the indoor unit P
It is received by the remote control communication unit 32 of No. 1 and sent to the operation control unit 31.

Next, the operation control unit 31 reads the PAC address set by the address setting switch and generates address setting data that combines this PAC address and the character string transmitted from the remote controller R1. In this example, the PAC address is "PAC_1" and the character string is "A conference room", so the data generated here is
“PAC_1 =“ A meeting room ””. Then, the operation control unit 31 transmits the address setting data generated here to the air conditioning communication device 4 via the control network communication unit 33. The address setting data is received by the control network communication unit 43 of the air conditioning communication device 4 and output to the control unit 41.

Next, the control unit 41, among the objects 7 stored in the storage unit 42 in advance, corresponds to the PAC address (here, PAC_1) included in the address setting data transmitted from the indoor unit P1. The installation location name character string (here, A conference room) included in the address setting data is assigned to the “object name” property of the object 7 having the identification number 8.

Then, the worker goes to the B conference room and performs the above-mentioned work, whereby two objects are stored in the storage section of the air conditioning communication device 4. By performing this operation for all the indoor units Pn under the control of the air conditioning communication device 4, as many objects 7 as the number of indoor units are stored in the storage unit 42.

Next, the control unit 41 transmits an entry communication sequence of "initialization completed" to the building management host 1 via the building management network communication unit 44 based on the standard of the communication protocol. In response to this, the building management host 1 sequentially reads all the objects 7 stored in the storage unit 42 of the air conditioning communication device 4 in the order of the object identification number, and obtains the mapping information of the object identification number and the installation place name. get. As a result, the mapping information of the object identification number and the installation place name is stored in the building management host 1, and it is recognized in which room the indoor unit having the object identification number is installed. can do.

Next, the building management host 1 generates and displays a driving operation screen 11 based on the installation place name stored inside. Then, when a driving operation is performed, it is realized by performing an operation for this installation place name. For example, operations such as starting operation (ON) of the "A meeting room" and stopping operation of the "B meeting room" (OFF) are performed. In response to this driving operation, the building management host 1 sends a control command to the air conditioning communication device 4 using the object number corresponding to the name of the installation place where the driving operation was performed. For example, when starting the operation of the indoor unit P1 installed in the A conference room, the object identification number 8 corresponding to the A conference room is set.
And a control code meaning start of operation to the air conditioning communication device 4. In this example, "001 =" ON "". In response to this, the control unit 41 of the air conditioning communication device 4 receives the object identification number “00” transmitted from the building management host 1.
The PAC address "PAC_1" corresponding to "1" is read from the storage unit 42, and a control code that means the start of operation is transmitted to this PAC address. As a result, the indoor unit P1 starts operating.

As described above, in the building management host 1, it is possible to perform the driving operation based on the installation location name without paying attention to the PAC address of the indoor unit Pn. Also, since the PAC address can be determined by the convenience of the air conditioner side, consult with the building management host in advance and refer to "Installation place name (room name) -PAC address correspondence table".
It is possible to confirm the operation without exchanging.

Next, the operation of deciding the installation place name of each indoor unit Pn on the building management host 1 side, downloading the character string to the remote controller Rn via the air conditioning communication device 4, and displaying it on the remote controller will be described. First, building management host 1
Is the air-conditioning communication device 4 when the installation place name is changed.
Write the installation location name character string in the "object name" property of each object in the building management standard communication. In response to this, the control unit 41 of the air conditioning communication device 4 updates the contents of the object 7 stored in the storage unit 42, and at the same time, sets the installation location name character string written in the “object name” property of each object. Is transmitted to the indoor unit Pn having the PAC address corresponding to the object identification number. Here, it is assumed that the A conference room in which the indoor unit P1 is installed is changed to the C conference room.

Next, the operation controller 31 of the indoor unit P1 which has received the installation place name transmits the received installation place name (C conference room) to the remote controller R1. In response to this,
The control unit 23 of the remote controller R1 outputs the received installation place character string to the display unit 25. As a result, the remote controller R1
A new installation place name is displayed on the display 26 of.

In this way, by downloading from the building management host 1 to the remote controller Rn, if the installation place name is changed on the building management host 1 side after the above-mentioned operation, the building management host 1 changes the name. The character string of the subsequent installation location can be downloaded to the remote controller Rn via the air conditioning communication device 4, and the location recognized by the building management host 1 is displayed on the remote controller of each indoor unit. Can be easily found.

Next, an installation location name transmission type air conditioner according to another embodiment will be described with reference to FIGS. Figure 7
[Fig. 6] is a block diagram showing a configuration of another embodiment. In this figure, the same parts as those of the device shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. The configuration shown in FIG. 7 is different from the configuration shown in FIG. 1 in that the air conditioning communication device 4 is omitted and each indoor unit P1a, P2a is directly connected to the building management communication network 2, and in the configuration shown in FIG. Is that each indoor unit stores the object 7 stored in the air conditioning communication device 4. Further, since the current operation status is stored as the current value property 12, and the indoor unit is connected to the building management communication network 2, the packaged air conditioner outdoor unit P0 (not shown in FIG. 1) is also connected to the building management communication network 2. Connected to.

Next, the address setting operation will be described step by step with reference to FIGS. In the following description, the building management communication network 2 includes two indoor units P1a and P1.
It is assumed that only 2a is connected, and the indoor unit P1a is
It is assumed that the indoor unit P2a is installed in the A conference room and the indoor unit P2a is installed in the B conference room. First, the operator of the company in charge of the air conditioner operates the address setting switch (not shown) provided in the indoor unit P1a to set the PAC address. Here, the PAC address of the indoor unit P1a is “PAC_1”. The address value to be set at this time does not need to be decided in advance, and may be set independently for the convenience of the operator in charge of the air conditioner. Subsequently, the worker sets the PAC address of the indoor unit P2a. The address value set at this time may be any value as long as it can uniquely identify the indoor unit under the building management communication network 2. Here, the indoor unit P2a
The PAC address of the above is “PAC_2”.

Next, the worker goes to the A conference room and operates the key switch 21 of the remote controller R1 to input the installation place name (in this example, "A conference room"). The key input analysis unit 22 determines whether the input key is an input operation of the installation place name or an operation operation, and when the input operation is the input operation of the installation place name, each key of the key switch 21 is pressed. The kana data assigned to the control unit 23 is sent to the control unit 23. In response to this, the control unit 23 transfers this kana-data to the kana-kanji conversion unit 24 and performs kana-kanji conversion processing. Then, the control unit 23 holds the character string subjected to the Kana-Kanji conversion inside and sends it to the display unit 25. In response to this, the display unit 25 converts it into display data and outputs it to the display unit 26.
As a result, the name of the installation location (in this example, "A conference room") is displayed on the display 26. The operator refers to this display content and confirms whether the input content is correct or not.

Next, if the input content is correct, the operator inputs the character string by inputting a predetermined key switch 21. In response to this, the key input analysis unit 22 notifies the control unit 23 that the confirmation operation has been performed. In response to this, the control unit 23 transmits the input character string (installation place name) to the indoor unit P1a via the communication unit 27. The character string data is received by the remote control communication unit 32 of the indoor unit P1 and sent to the operation control unit 31.

Next, the operation control unit 31 reads the PAC address set by the address setting switch and generates address setting data that combines this PAC address and the character string transmitted from the remote controller R1. In this example, the PAC address is "PAC_1" and the character string is "A conference room", so the data generated here is
“PAC_1 =“ A meeting room ””. Then, the operation control unit 31 outputs the address setting data generated here to the control unit 41. Subsequently, the control unit 41 controls the indoor unit P1.
