In this example, it is provided in the control unit 40 in the remote controller, but a similar one can be provided in the indoor unit.

Next, the operation of this embodiment of the multi-type air conditioner will be described. For example, as shown in FIG. 7, indoor units (A) 2, (B) 3, and (C) 4 are connected to the outdoor unit 1, and indoor units (D) 13 and (E) 14 are connected to the outdoor unit 12. There is. Local remote controllers 5 and 15 are connected to the indoor units (A) 2 and (D) 13, respectively, and the outdoor units 1 and 12 are connected to the air conditioning management device 16 via the transmission conversion device 11, respectively. The operation is controlled by the air conditioning management device 16. First, the operation will be described by taking the case where the operation setting of the indoor units (A) 2 to (C) 4 is performed by the air conditioning management device 16 as an example. Outdoor unit 1
8 has the configuration shown in FIG. 8, and when the outdoor unit 1 receives the operation setting contents from the air conditioning management device 16 by the transmission conversion device 11, the air conditioning unit operation setting means 23 controls all indoor units. The simultaneous operation content is determined, the outdoor unit processing unit 24 controls the outdoor unit in accordance with the determined operation content, and the indoor / outdoor communication transmitting means 22 is performed.
The operation details are displayed in the indoor unit (A) 2 and the indoor unit (B)
3, Send to the indoor unit (C) 4. Indoor unit (A) 2
As shown in FIG. 3, when the indoor / outdoor communication receiving means 31 receives the operation content, the operation setting means 35 determines the operation content, and the indoor unit processing section 3 to (C) 4 follow the determined operation content.
At 6, the indoor unit is controlled. At this time the indoor unit
(A) 2 transmits the operation content and operation status data to the local remote controller 5 by the remote controller communication transmitting means, and the local remote controller 5
As shown in FIG. 10, when the remote control communication receiving means 41 receives the operation content and the operation status from the indoor unit (A) 2, the remote control processing section 43 informs the display section or the like (not shown).

Next, the operation will be described by taking as an example the case of setting the operation by the remote controller 5 at hand. The indoor unit (A) 2
When the remote controller communication receiving means 33 receives the operation setting content transmitted from the local remote controller 5, the operation setting means 35 determines the operation content, and the indoor unit processing section 36 controls the indoor unit according to the determined operation content. At the same time, the indoor / outdoor communication transmitting means 32 and the remote controller communication transmitting means 34 transmit the operation content and the operation status data to the outdoor unit 1 and the local remote controller 5. In the outdoor unit 1, when the indoor / outdoor communication receiving means 21 receives the operation content, the air conditioning unit operation setting means 23 determines the simultaneous operation content of all the indoor units, and the outdoor unit processing unit 24 according to the determined operation content. The outdoor unit is controlled, the indoor / outdoor communication transmitting means 22 transmits the operation content to the indoor unit (A) 2, the indoor unit (B) 3, the indoor unit (C) 4, and the transmission conversion device 11 The operation content and operation status are transmitted to the air conditioning management device 16. When the indoor / outdoor communication receiving means 31 receives the operation content, the indoor units (A) 2 to (C) 4 determine the operation content by the operation setting means 35, and the indoor unit processing unit 36 follows the determined operation content. In this way, the air conditioner management device 16 can perform centralized management and operation control of the air conditioner without complicated construction by only providing the outdoor unit with the transmission conversion device. Such a transmission conversion device for performing signal conversion between indoor / outdoor communication and outdoor / upper controller communication may be incorporated in the control device in advance as shown in FIGS. 8 and 9, or after the configuration shown in FIGS. It may be added as an adapter.

The operation of this embodiment of the multi-type air conditioner will be described. The indoor unit (A) 2 to the indoor unit (C) 4 transmit preset functions (for example, louver function, vaneswing function, etc.) of the own unit to the outdoor unit 1 by the indoor / outdoor communication transmitting means 32. In the outdoor unit 1, when the indoor / outdoor communication receiving means 21 receives the function information of each indoor unit (A) 2 to (C) 4, the remote controller function setting means 71 sets the operation by the local remote controller or the controller of the air conditioning management system. The possible items are determined, and the indoor / outdoor communication transmitting means 22 transmits the function information to the indoor unit (A) 2. The indoor unit (A) 2 transmits the function information received by the indoor / outdoor communication receiving means 31 to the local remote controller 5 by the remote controller communication transmitting means 34, and the local remote controller 5 receives the indoor unit by the remote controller communication receiving means 42.
(A) When the function information from 2 is received, the function setting means 81
Set the items that can be operated by yourself. For example, when the outdoor unit 1 has the vane as the remote controller function information and no swing is set, the local remote controller 5 causes the remote controller processing unit 43 via the function setting means 81 to set the vane swing by the setting switch (not shown), that is, the up and down wind direction. Process to disable the continuous operation setting of. Also,
Similarly, in the case of the air conditioning management device, the outdoor unit 1 can set the operable items by transmitting the function information via the transmission conversion device 11. In this way, items that can be operated by the remote control can be set without being limited to the functions of the indoor units connected to the remote control. The function setting means 81 may be provided not in the remote controller but in the indoor unit, and the function information by remote control operation may be converted and operated by the indoor unit.

Furthermore, the operation of this embodiment of the multi-type air conditioner will be described. The indoor unit (A) 2 to the indoor unit (C) 4 have preset functions of their own unit (eg, louver function, vaneswing function, etc.)
Is transmitted to the outdoor unit 1 by the indoor / outdoor communication transmitting means 32. When the outdoor unit 1 receives the function information of each indoor unit (A) 2 to (C) 4 by the indoor / outdoor communication receiving means 21,
The remote-control function setting means 71 determines the items which can be set by the remote controller at hand or the controller of the air-conditioning management system by the logical sum of the functions of each indoor unit, and the indoor / outdoor communication transmitting means 22 determines the function information to the indoor unit ( A) Send to 2. The indoor unit (A) 2 uses the remote control communication transmitting means 34 to transmit the function information received by the indoor / outdoor communication receiving means 31.
When the remote controller 5 receives the function information from the indoor unit (A) 2 by the remote controller communication receiving means 42, the remote controller 5 sets the item which can be operated by the function setting means.

For example, the indoor unit (A) 2 is "with louvers and no swing", the indoor units (B) 3, (C) 4
Is set to “without louver, with swing”, the outdoor unit 1 sets the logical sum “with louver, with swing” as remote control function information, and the setting content is set via the indoor unit (A) 2. It transmits to the local remote controller 5, and the local remote controller 5 receives the remote controller communication receiving means 41,
If the louver setting, that is, the continuous operation setting in the left and right wind direction, and the vaneswing setting, that is, the continuous operation setting in the up and down wind direction are both enabled by the setting switch (not shown) through the function setting means 81, and both are set. Simultaneously transmits a louver setting = "ON" signal and a vane setting = "Swing" signal. The indoor unit (A) 2 to which the local remote controller 5 is connected simultaneously receives the louver setting = "ON" signal and the vane setting = "Swing" signal together with other operation setting information by the remote control communication receiving means 33. . Indoor unit (A) 2
Has information about his / her own function “with louvers and without swing”
Therefore, the louver, which is the content that can be controlled by the own unit = “ON”, that is, the continuous operation in the left and right wind direction is performed.
Further, since the indoor unit (A) 2 does not have a swing function, continuous operation in the up and down wind direction is not performed, but the indoor / outdoor communication transmitting means 32 together with other operation setting information together with the louver setting = "ON" signal and the vane setting. = "Swing"
Is transmitted to the outdoor unit 1.

The outdoor unit 1 has an indoor / outdoor communication receiving means 2
When the operation setting is received at 1, the indoor / outdoor communication transmitting means 22 sends a signal of louver setting = "ON" and a signal of vane setting = "Swing" together with other operation setting information to the indoor unit (A) 2 to the indoor unit ( C) Send to 4 at the same time.
Since the indoor units (B) 3 and (C) 4 have the function of “without louver and with swing”, when the operation setting is received by the indoor / outdoor communication receiving means 31, continuous operation in the left and right wind directions is not performed, and the vaneswing is performed. That is, continuous operation in the up and down wind direction is performed. In this way, in the conventional simultaneous operation multi air conditioner, if the model to which the remote control is connected does not have the swing function, the vane setting is required even if the other indoor units connected to the same outdoor unit are also the swing models. It is not possible to make the swing, and if the model to which the remote control is connected does not have the louver function, it is impossible to turn on the louver even if other indoor units are louver models. What was there is now possible with the simultaneous operation multi-air conditioner of this embodiment.

In the above example, the louver / swing models are mixed, but the same applies to the case where the models having two stages of wind speed switching function, the models having four stages, and the models without switching are mixed. Yes, the outdoor unit 1 sets “4 speeds of wind speed switching” which is a logical sum as remote control function information, and transmits the setting content to the local remote control 5 via the indoor unit (A) 2,
The remote controller 5 validates the wind speed setting of weak wind, medium weak wind, medium strong wind, and strong wind by the setting switch (not shown) in the remote control processing unit 43 via the remote control communication receiving means 41 and the function setting means 81. Works like. For example, if the indoor unit (A) 2 is a model without wind speed switching,
(B) 3 is a model with two-stage wind speed switching, indoor unit (C) 4 is a model with four-stage wind speed switching, and when the wind speed is set to "medium strong wind" with the remote control at hand, the indoor unit (A) 2 is Since there is no switching, the indoor / outdoor communication transmitting unit 32 transmits the wind speed = “medium strong wind” by operating in strong wind with the wind speed fixed. Since the indoor unit (B) 3 is a two-stage wind speed switcher, it is decided in advance that weak wind, medium weak wind, and medium strong wind settings are received, and weak wind is received and strong wind is received when strong wind is received. It is operated by weak wind by receiving "medium strong wind". Since the indoor unit (C) 4 has four stages of wind speed switching, it operates with the received "medium strong wind".

As described above, in the conventional multi air conditioner, when the model to which the remote controller is connected is the model without wind speed switching, the other indoor unit connected to the same outdoor unit is the model with two or four stages of wind speed switching. Even if there is, it is impossible to carry out the wind speed switching control, and if the model to which the remote controller is connected is the wind speed switching 2-stage model, even if the other indoor unit is the wind speed switching 4-stage model, Although it is impossible to perform the four-stage wind speed switching control, the multi-air conditioner of the present embodiment makes it possible. That is, the items that can be operated by the remote controller are not limited to the functions of a specific indoor unit, and all the functions originally possessed by the installed indoor unit can be set. Similarly, in the case of the air conditioning management device, the outdoor unit 1 can set the operable items by transmitting the function information via the transmission conversion device 11.

As described above, in this multi-type air conditioner,
Control information is transmitted and received between the transmission conversion device of the outdoor unit and the controller of the air conditioning management system that centrally manages a plurality of air conditioners, and the operation setting and management of the multi-type air conditioner is performed by the controller of the air conditioning management system. That is, the multi-type air conditioner is equipped with a transmission conversion device in the outdoor unit, transmits and receives control information to and from the controller of the air conditioning management system that centrally manages multiple air conditioners, and the multi-type air conditioner is controlled by the controller of the air conditioning management system. Since the operation setting and management are performed, the air-conditioning management device 16 can be provided inexpensively without complicated construction by providing a transmission conversion device in the outdoor unit instead of in the indoor unit with a large number and difficult to be post-constructed. This has the effect of enabling centralized management and operation control of air conditioners. Further, even in an indoor unit that does not have a space for installing the transmission conversion device, it is possible to perform centralized management and operation control of the air conditioner by the air conditioning management device 16.

Further, in this multi-type air conditioner, the function information of each indoor unit is collected by the indoor / outdoor communication receiving means of the outdoor unit, and the operation can be set by the remote controller function setting means by the local remote controller or the controller of the air conditioning management system. And send it to the local remote controller through the indoor unit,
The local remote controller automatically sets the function operable by the function setting means according to the information received by the remote control communication receiving means.

That is, in this multi-type air conditioner, the function information of each indoor unit is collected by the indoor / outdoor communication receiving means provided in the outdoor unit, and the operation can be set by the remote controller function setting means by the local remote controller or the controller of the air conditioning management system. It decides the item and sends it to the local remote controller through the indoor unit, and the remote controller function setting means automatically sets the operable function according to the information received by the local remote controller communication receiving means provided in the local remote controller. The operable item can be set without being limited by the function of the indoor unit connected to the remote controller.

Also, in this multi-type air conditioner, the indoor / outdoor communication receiving means of the outdoor unit collects the function information of each indoor unit, and the remote control function setting means performs the remote control function by the logical sum of the function information of each indoor unit. Set.

That is, in this multi-type air conditioner, the indoor / outdoor communication receiving means provided in the outdoor unit collects the function information of each indoor unit, and the remote control function setting means uses the logical sum of the function information of each indoor unit to obtain the above-mentioned information. Since the remote control function is set, all the functions originally possessed by the installed indoor unit can be set without limiting the items that can be operated by the remote control to specific indoor units.

The unit function setting changing means changes the setting of the function of the unit displayed in 3.

Next, the operation will be described with reference to the flowcharts of FIGS. First, the operation of the indoor unit will be described based on the flowchart of FIG. When the power supply of the indoor unit is turned on, the model of its own unit is set by inputting switches and jumper settings in step S111 (own unit model setting means 122).
Then, in step S112, the model data of the own unit stored in the own unit model storage means 123 such as a non-volatile memory is compared with the model data newly set in step S111. As a result of the comparison, if it is determined in step S113 that the model data is different, step S1
At 14, the model data newly set at step S111 is stored in the own unit model storage means 123, and at step S115, the function data initial for each model stored in the all model function initial value storage means 124 is initialized. The set value is read out, and in step S116, the function corresponding to the newly set model data is set as the function of the self unit from the function data initial value for each model (self unit function setting means 1
25) after that, in step S117, the function information of the self unit is stored in the self unit function storage means 12 such as a nonvolatile memory.
Remember at 6. As a result of comparing the model data in step S113, if the model data match, step S113
At 116, the previously set value is used as the function of the own unit. This setting is performed, for example, by changing the setting of the storage means (RAM) provided inside the control device 121 of FIG. 13 for controlling the operation of the indoor unit if the data is necessary for operating the indoor unit. Further, the contents are similarly set and changed in the own unit function storage means 126 which is a non-volatile memory. If it is determined in step S118 that the remote control communication unit 127 has received the function information data from the remote controller, and in step S119 that the received data is the function information data for the own unit, in step S120, according to the received content, The function information is newly set (updated), the function information is stored in the own unit function storage means 126 in step S121, and the function information is transmitted to the outdoor unit by the indoor / outdoor communication means 128 in step S122. Here, if it is determined in step S119 that the received data is not the function information data regarding the own unit, steps S120 and S121 are not performed, and step S122 is performed.
Send the received data to the outdoor unit at. Step S
After 122, or in step S118, the function information data is not received from the remote controller, it is determined in step S123 that the function information data is received from the outdoor unit by the indoor / outdoor communication unit 128, and the received data is sent to the own unit in step S124. When it is determined that the data is the function information data, the function information is newly set (updated) in step S125 according to the received content, and step S126.
The function information is stored in the own unit function storage means 126 at, the function information is transmitted to the remote controller by the remote control communication means 127 at step S127, and the process returns to the reception waiting state at step S118. Here, if it is determined in step S124 that the received data is not the function information data regarding the own unit, steps S125 and S126 are not executed, and the received data is transmitted to the remote controller in step S127.
In step S123, the function information data is not received from the outdoor unit, and in step S128, the remote controller communication means 12
7 or the operation control data is received by the indoor / outdoor communication unit 128, the operation control is performed according to the received contents in step S129, and the process returns to the reception waiting state in step S118. If the operation control data from the remote controller or the outdoor unit is not received in step S128, the process returns to the reception waiting state in step S118.

In this way, when the function information data whose setting is changed and transmitted from the remote controller is the content of the own unit, the function setting change process of the own unit is executed and another unit (outdoor unit or another indoor unit) Data is transmitted to the outdoor unit or another indoor unit through the indoor / outdoor communication unit 128, and each unit changes the setting of its own function when receiving information of its own unit, so the remote controller connection position is arbitrary. Well, no need to reconnect.

Next, the operation of the outdoor unit will be described with reference to FIG.
A description will be given based on the flowchart of FIG. When the power supply of the outdoor unit is turned on, the model of the own unit is set (the own unit model setting means 132) by inputting switches and jumper settings in step S131, and then in step S13.
In 2, the own unit model storage means 13 such as a non-volatile memory
The model data of the own unit stored in 3 is compared with the model data newly set in step S131.
As a result of the comparison, when it is determined that the model data is different in step S133, the model data newly set in step S131 is stored in the own unit model storage means 133 in step S134, and in step S135,
The function data initial setting values for each model stored in the function initial value storage means 134 for all models are read out, and step S136
In the function data initial value of each model, the function corresponding to the newly set model data is set to the function of the own unit (own unit function setting means 135), and then in step S137, the own unit is set. Function information is stored in its own unit function storage means 136 such as a non-volatile memory. As a result of comparing the model data in step S133, if the model data match, in step S136, the previously set value is used as the function of the own unit. If it is determined in step S138 that the indoor / outdoor communication unit 137 has received the function information data from the indoor unit, and in step S139 that the received data is the function information data for the own unit, the process proceeds to step S140 according to the received content. Function information is newly set (updated), and step S14
In step 1, the function information is stored in the own unit function storage means 136, and in step S142, the indoor / outdoor communication means 137 transmits the function information to all indoor units.
Return to the reception waiting state of 8. In step S138, the function information data is not received from the indoor unit,
When the operation control data is received by the indoor / outdoor communication unit 137 in step 3, operation control is performed according to the received contents in step S144, and the process returns to the reception waiting state in step S138. If the operation control data from the indoor unit is not received in step S143, the process returns to the reception waiting state in step S138.

Next, the operation of the remote controller will be described with reference to FIG. The remote controller, when the unit function setting changing means 144 shifts to the unit function setting changing mode by, for example, a switch operation, the remote controller communication means 142.
The functional information of all indoor units and outdoor units is collected from the indoor unit, and the unit function display means 143 displays the unit setting selected by the switch operation and the current setting data in the setting change item. Further, when there is a setting change input by a switch operation, it is transmitted to the indoor unit by the remote control communication means 142 and displayed by the unit function display means 143.

Next, another embodiment will be described with reference to FIG. In FIG. 18, reference numeral 141 is a remote controller control section for controlling each remote controller, 142 is a remote controller communication means for transmitting and receiving operation information and function information to and from the indoor unit, and 143 is a unit function display means for displaying functions of each indoor unit and outdoor unit. 144 to 146 are unit function setting changing means 1 to n for changing the setting of the function of the unit displayed on the unit function displaying means 143. The unit function setting changing means 1 to n are, for example, for each item to be changed. Different input means are provided. For example, a case will be described in which the item is divided into two types, an item set by an installation worker at the time of initial installation and an item set by a service provider in response to a request from a customer. At the time of initial installation, the item set by the installation operator shifts to the setting mode by pressing the unit function setting changing means 1, for example, the switch A, and the item set by the service provider in response to a request from the customer is the unit function setting change. By pushing the means 2, for example, the switch B, the mode is changed to the setting mode. The installation company changes the blown air volume according to the height of the installation location or the condition of dirt, or changes the filter clogging detection time in response to dirt. On the other hand, the service provider changes the function according to the customer's request such as setting of antifreezing temperature and presence / absence of swing. That is, in the remote controller of this embodiment shown in FIG. 20, when the mode is changed to the setting mode by the switch A (unit function setting changing means 144), only the items set by the installer, for example, item numbers 1 to 10 are displayed as unit functions. It is displayed by the means 143. For example, when selecting an item with the up / down keys 151, 152, item numbers 1-10 are sequentially displayed on the item display unit 153 every time the up / down key is input, and the item selected from the items 1-10 is displayed. The setting can be changed. Further, when the mode is changed to the setting mode by switch B (unit function setting changing means 145),
Items set by the service provider, for example, item numbers 11 to 20
Only the unit function display means 143 displays it. Similarly, when selecting an item with the up / down keys 151, 152, the item numbers 11 to 20 are sequentially displayed on the item display unit 153 each time the up / down key is input, and the item selected from the items 11-20 is displayed. The setting can be changed. By thus dividing the operation for shifting to the mode, it is possible to classify the items whose settings can be changed according to the types of the items whose settings are changed.

Next, another embodiment will be described with reference to FIGS. FIG. 20 is a block diagram showing a control device for an indoor unit using an embodiment of the multi-type air conditioner, and FIG. 21 is a flowchart showing an operation of the control device for the indoor unit. In FIG. 20, reference numeral 129 is a wireless signal receiving means for receiving an inspection signal including an address code from the wireless remote controller. The operation will be described with reference to the flowchart of FIG. When the indoor unit receives the inspection request signal including the address code from the wireless remote controller in step S151, the indoor unit determines whether the received address code matches the predetermined address in step S152. If the received address code matches the predetermined address, for example, 50, the function information setting change mode is entered in step S153. After shifting to the function information setting change mode, when the inspection request signal including the address code from the wireless remote controller is received again in step S154, the item whose setting is to be changed is determined in step S155 corresponding to the received address code. For example, when the address 3 is received, the mode is changed to the setting change mode of the air volume UP. When the inspection request signal including the address code from the wireless remote controller is received again in step S156, step S15 is performed corresponding to the received address code.
At 7, the contents to be changed are confirmed. For example, when the address 2 is received, the air volume UP setting 2 is set. In step S158, the function of the self unit is changed according to the confirmed setting change item and setting change content. In step S152, when the received address code does not match the predetermined address, for example, 50, it is recognized as a normal inspection request signal, and in step S160, the past abnormal code is output by the buzzer, LED, etc. After performing the self-diagnosis, the process returns to the reception waiting state of step S151.
Further, in step S151, the inspection request signal including the address code is not received from the wireless remote controller,
When the operation data is received in 161, the operation is controlled in step S162 according to the received data, and the operation is performed in step S1.
Return to the reception waiting state of 51. Even when the operation data is not received in step S161, the process returns to the reception waiting state in step S151.

In the present embodiment, an example in which the function of the unit that receives the wireless signal is changed has been shown. However, as in the present embodiment, by further receiving the inspection request signal including the address code from the wireless remote controller, the target The unit may be selected. In this case, if the content is other than the content of the own unit, the indoor / outdoor communication unit 128 transmits it to the outdoor unit or another indoor unit to set the other unit.

Further, when T0 has elapsed after receiving the data 10, all the indoor units finish the transmission processing and shift to the reception processing. The outdoor unit transmits the next control data (data 20) when T0 has elapsed after transmitting the data 10. Transmission timing T0 of the outdoor unit at this time
Is set based on the transmission time per indoor unit by the number of connected indoor units set by the connected number setting means. The above communication operation is an example of using an inexpensive communication circuit that cannot transmit and receive between indoor units, and is not limited to this.

Next, the operation will be described with reference to the flowcharts of FIGS. 24 and 25 and the timing chart of FIG. In this embodiment, the case where the predetermined logical code is "1" will be described, but the predetermined logical code may be "0" or a combination of "1" and "0". FIG. 24 is a flowchart showing the operation of the indoor unit connection number setting means in the outdoor unit. In the figure, after the outdoor unit 1 is powered on, in step S101, an identification code request is transmitted to all indoor units ((A) 2 to (C) 4 and indoor units (not shown)) by a transmission circuit 22 for indoor / outdoor connection. Send over lines 6-8. It waits until the identification code is received from the indoor unit in step S102, and when the reception circuit 21 receives the identification code via the indoor / outdoor connection lines 6 to 8, a predetermined logical code of the identification code received in step S103. (The number of logic "1" in this embodiment) is counted. In steps S104 to S103, the identification code is given a fixed number of times n1.
The process is repeated until it is determined that the identification code has been received, and if it is determined that the identification code has been received a predetermined number of times n1, step S10.
In step 5, the maximum value of the number of logic "1" counted in step S103, which is executed n1 times, is calculated. logic"
The maximum value of the number of 1 "is set to a constant value m1 in step S106.
In step S107, the quotient obtained by division is set as the number of connected indoor units connected to the own unit.

Here, the logic "1" means that when a plurality of indoor units simultaneously transmit the logic "1" and the logic "0",
The outdoor unit 1 is a code which is set by the receiving circuit 21 so as to receive the logic "1".

FIG. 25 is a flow chart showing the operation of the identification code setting means and the identification code transmission means in the indoor unit. Steps S111 and S112 show the operation of the identification code setting means, and steps S113 and S114 show the operation of the identification code transmitting means. In the figure, indoor units (A) 2 to (C)
4 and the indoor unit (not shown) stand by until the identification code request from the outdoor unit 1 is received in step S111 after the power is turned on, and the reception circuit 31 requests the identification code via the indoor / outdoor connection lines 6 to 8. Is received, step S112
At, the identification code is set so that the number of logic "1" s of the code string to be transmitted becomes a constant value m1. This constant value m1 is the same as the constant value m1 in step S106 of the outdoor unit shown in FIG. Further, the identification code is arbitrarily set every time the identification code request is received from the outdoor unit 1 in step S111, for example, by calculation from a random number or a timer count value of a microcomputer. Step S11
At 3, wait until the transmission timing of the identification code,
When it comes to the transmission timing of the identification code, step S11
At 4, the transmission circuit 22 transmits the identification code to the outdoor unit 1 through the indoor / outdoor connection lines 6 to 8. Here, the transmission timing of the identification code in step S113 is, for example, a certain time after the signal is received from the outdoor unit 1 so that the transmission timings of all the indoor units become the same.

FIG. 26 shows the number (m of logic "1" of the identification code.
2 is a timing chart showing the operation in the case where 1) is 2, and the number of indoor units connected to the outdoor unit 1 is three (A) 2 to (C) 4. The outdoor unit transmits the identification code request signal (signal 101) by the transmission circuit 22 via the indoor / outdoor connection lines 6 to 8. (FIG. 24 Step S10
1) The indoor units (A) 2 to (C) 4 set the identification code by the identification code setting means (step S112 in FIG. 25) so that the number of logic “1” s of the code string to be transmitted becomes a constant value 2. Then, in the identification code transmitting means (step S114 in FIG. 25), the outdoor unit 1 transmits the “identification code request” for a certain time t so that the transmission start timings of all the indoor units are the same, as shown in the figure. At the same time, the identification code is transmitted from bit 1 at the same time. (Signals 102 to 104) The outdoor unit receives the reception circuit 2 via the indoor and outdoor connection lines 6 to 8.
1 receives the OR code / signal 105 of the identification code (see FIG.
4 step S102), and the indoor unit connection number automatic setting means (steps S103 to S107 in FIG. 24)
Set the number of connected indoor units. In this embodiment, the number of logic "1" s of the counted signal 105 is 6 (step S105), and the signal 105 is divided by a constant value 2 (step S1).
06) and the quotient is 3, so the number of connected indoor units connected to the own unit is set to 3 (step S
107).

In this embodiment, the indoor unit operates in step S.
At 112, the identification code is set so that the number of logical "1" s in the code string is the constant value m1 = 2.
Then, since the quotient obtained by dividing the maximum value of the number of received logical "1" by 1 is set as the connected number, the maximum value of the number of received logical "1" is the connected number. In addition, transmission / reception of the identification code is performed by n1.
Although repeated, the probability of erroneous setting of the number of connected devices can be reduced by increasing n1. Further, by increasing the number m1 of the logic "1" of the identification code, the probability that the identification codes arbitrarily set by all the indoor units by the random numbers and the like will be reduced, and the probability of erroneous setting of the number of connected units can be further reduced. It is possible.

Further, in this embodiment, the outdoor unit 1 is
After transmitting the "identification code request", the indoor unit transmits the identification code from bit 1 at the same time when a predetermined time t has passed. Therefore, it may be possible to transmit at the same time at regular intervals.

Steps S201 to S206 are means for setting the number of connected indoor units,
Steps S207 to S211 show indoor unit identification number setting means, and step S212 shows the number of connected units, identification numbers and identification code transmission means. In the figure, after the outdoor unit 1 is powered on, in step S201 all indoor units ((A)
2 to (C) 4 and an indoor unit (not shown), an identification code request is transmitted by the transmission circuit 22 through the indoor and outdoor connection lines 6 to 8. In step S202, the process waits until the identification code from the indoor unit is received, and the indoor / outdoor connection lines 6 to 8 are connected.
When the receiving circuit 21 receives the identification code via the, the number of logic "1" of the received identification code is counted in step S203. This step S201 to step S203
Up to a certain number of times n in step S204
The process is repeated until it is determined that the identification code has been received once, and if it is determined that the identification code has been received a certain number of times n1, step S2
At 05, the maximum value of the number of logic "1" counted at step 203 is calculated. In step S206, the maximum value of the number of logical "1" is set to the number of connected indoor units connected to the own unit. When the number of connected indoor units is set in step S206, step S207
Then, the transmission circuit 22 transmits the identification code request to all the indoor units ((A) 2 to (C) 4 and the indoor unit (not shown)) via the indoor / outdoor connection lines 6 to 8. Step S20
Waiting until the identification code is received from the indoor unit at 8, and when the identification code is received at the receiving circuit 21 via the indoor / outdoor connection lines 6 to 8, the logic "1" of the identification code received at step S209 is set. Count the number. In step S210, the counted number of logic "1" is compared with the number of connected indoor units set in step S206. If they match, the identification number is set in step S211.
At this time, the identification numbers are set, for example, in ascending order of the identification code. The number of connected indoor units and identification numbers set in step S206 and step S211 and the identification code received last from each indoor unit are set in step S2.
At 12, the information is transmitted to each indoor unit (A) 2 to (C) 4 and an indoor unit (not shown). Logic "1" in step S210
As a result of the comparison between the number of No. and the number of connected indoor units, if they do not match, the identification code request transmission in step 207 is performed again.

FIG. 28 is a flow chart showing the operation of the identification code setting means, the identification code transmission means, the transmission identification code storage means and the own unit identification number setting means in the indoor unit. Steps S221 and S222 show the operation of the identification code setting means, steps S223 and S224 show the operation of the identification code transmitting means, step S225 shows the operation of the transmission identification code storing means, and steps S226 to S229 show the operation of the own unit identification number setting means. In the figure, indoor units (A) 2 to (C)
4 and the indoor unit (not shown) receive the identification code request from the outdoor unit 1 by the receiving circuit 31 in step S221 after the power is turned on, and in step S222, the number of logic "1" of the code string to be transmitted is changed. The identification code is set to be 1. The setting of the identification code is arbitrarily set by, for example, a random number, a calculation from the timer count value of the microcomputer, or the like each time the identification code request is received from the outdoor unit 1 in step S221. In step S223, the process waits until the transmission timing of the identification code is reached. When the transmission timing of the identification code is reached, the identification code is transmitted to the outdoor unit 1 by the transmission circuit 32 in step S224, and the transmitted identification code is transmitted in step S225. Memorize in step S2
Return to 21. Until it is determined that the identification code request from the outdoor unit 1 is not received in step S221 and the number of connected units, the identification number, and the identification code are received from the outdoor unit 1 in steps S221 to S22.
Repeat 5 At this time, the identification code stored in step S225 is updated every time the identification code is transmitted in step S224. When it is determined in step S226 that the number of connected units, the identification code, and the identification code are received from the outdoor unit 1, the received data is analyzed in step S227, and the identification code of the data received in step S228 is The identification code transmitted last time (step S225
(Identification code stored in step 1), and if they match, the identification number received from the outdoor unit 1 with the same data as the identification code is set as the identification number of the own unit in step S229. If they do not match, step S221
Return to Each indoor unit controls its own unit based on the number of connected indoor units and the identification number transmitted from the outdoor unit 1.

FIG. 29 is a timing chart showing the operation when there are three indoor units (A) 2 to (C) 4 connected to the outdoor unit 1. The outdoor unit 1 transmits the identification code request signal (signal 201) by the transmission circuit 22 via the indoor / outdoor connection lines 6 to 8. (FIG. 27 Step S20
1 or step S207) Indoor units (A) 2 to (C) 4
Sets the identification code by the identification code setting means (step S222 in FIG. 28) so that the number of logical "1" s in the code string to be transmitted becomes a constant value 1, and the identification code transmission means (step S224 in FIG. 28). Then, the outdoor unit 1 transmits the identification code from bit 1 at the same time when a certain time t has passed after the "identification code request" is transmitted from the outdoor unit 1 as shown in the figure so that the transmission start timings of all the indoor units are the same. . (Signals 202 to 204) The outdoor unit is connected to the indoor and outdoor connection lines 6 to 8
The receiving circuit 21 receives the logical sum code (signal 205) of the identification code through the indoor circuit, and the indoor unit connection number automatic setting means (steps S201 to S206 in FIG. 27) sets the number of connected indoor units, The identification number of each indoor unit is set by the identification number setting means (steps S207 to S211 in FIG. 27). In this embodiment,
If the signal when the maximum value of the number of logic “1” is calculated in step S205 of FIG. 27 in the outdoor unit 1 is FIG. 29, the number of logic “1” of the counted signal 205 is 3
(Step S205), the number of connected indoor units connected to the own unit is set to 3 (step S206). If the outdoor unit 1 receives the same signal as in FIG. 29 again in step S208 in FIG. 27 after setting the number of connected units, the count number of the logic “1” of the signal 205 is 3 (step S209), and is determined in step S206. Since the number of connected indoor units is 3 (step S210), an identification number is set in step S211. For example, the identification numbers 1, 2, and 3 are set in order from the unit whose bit position number of the transmitted identification code is "1". In this embodiment, the indoor unit (C) 4 which has transmitted the identification code / signal 204 with the bit number 3 as the logic “1”
Of the indoor unit (A) 2 which has transmitted the identification code / signal 202 with the identification number 1 of 1 and the bit number 11 of logic “1”, the identification number / signal 203 of the indoor unit (A) 2 with the bit number 12 of logic “1” The identification number of the transmitted indoor unit (B) 3 is set to 3.

In the present embodiment, the identification code is set so that the number of logic "1" s of the code string transmitted by the indoor unit becomes 1, but when the outdoor unit sets the number of connected units (FIG. 27 step). In S201 to S206), the number of logic "1" of the identification code transmitted by the indoor unit is a constant value m1.
(M1 ≧ 2), and when the outdoor unit sets the identification number (steps S207 to S21 in FIG. 27).
In 1), as in this embodiment, if the number of logic "1" of the identification code transmitted by the indoor unit is set to 1,
The probability of erroneous setting of the number of connected indoor units can be reduced without increasing the number n1 of transmission / reception of identification codes when the number of connected outdoor units is set, and startup time can be shortened. In this case, in the outdoor unit, the same processing as step S106 in FIG. 24 is added between the processing in steps S205 and S206 in FIG.
In addition, the processing of the indoor unit is different when the outdoor unit sets the number of connected indoor units and when the indoor unit identification number is set, which is complicated. If the constant value m1 = 1 is set as in this embodiment, the processing of the indoor unit is common when the outdoor unit sets the number of connected indoor units and when the indoor unit identification number is set. it can. In this case, it is possible to reduce the probability of erroneous setting of the number of connected indoor units by increasing the number of times n1 of transmitting and receiving the identification code.

Here, the logic "1" means that a plurality of indoor units are logic "1" and logic "as in the embodiment of the air conditioner.
It means a code set so that the outdoor unit 1 receives the logic "1" in the reception circuit 21 when 0 "is simultaneously transmitted.

Next, another embodiment will be described with reference to FIGS. In this embodiment, like the other embodiments, the case where the predetermined logical code is "1" will be described. FIG. 30 shows the indoor unit connection number setting means, the indoor unit identification number setting means, and the connection number in the outdoor unit. 3 is a flowchart showing the operation of the identification number / identification code transmission means and the indoor unit identification number duplication detection means. Step S301 is indoor unit connected number setting means, step S302 is indoor unit identification number setting means, step S303 is connected number, identification number and identification code transmission means, and steps S304 to S308 are indoor unit identification number duplication detection means. Shows the operation of. In the figure, after the outdoor unit 1 is powered on, the number of connected indoor units is set in step S301, and in step S302, each indoor unit ((A) 2 to (C) 4 and indoor units not shown) is set. Set the identification number. The details of step S301 are
The same as steps S101 to S107 in FIG. 24 or steps S201 to S206 in FIG.
27 is the same as step S207 to step S211 in FIG. After setting the identification number of each indoor unit in step S302, in step S303, the number of connected indoor units, the identification number, and the identification code last received from each indoor unit are set to the indoor units (A) 2 to (C). 4) and the indoor unit (not shown). After transmitting the number of connected units and the identification number, in step S304, the duplicate detection code request is individually transmitted to the indoor unit having the identification number 1 by the transmission circuit 22 via the indoor / outdoor connection lines 6 to 8. Step S3
When the duplicate detection code is received by the receiving circuit 21 via the indoor / outdoor connection lines 6 to 8, the process waits until the duplicate detection code is received from the indoor unit having the identification number 1 at 05 (step S3).
When the number of logic "1" of the duplicate detection code received in 06 is counted and it is determined in step S307 that the number of logic "1" exceeds a fixed number m2, the process returns to step S301, Start again from the setting. If the number of logic "1" does not exceed the fixed number m2, this step S304-
Steps S307 to S307 are repeated until it is determined in step S308 that the duplicate detection code has been received a certain number of times n2, and when it is determined that the identification code has been received a certain number of times n2, duplicate detection for the indoor unit with the identification number 1 is performed. The process ends. This step S304 to step S3
08 is repeated by the number of connected indoor units from the indoor unit with the identification number 1. When all the units in steps S304 to S308 are completed, in step S309, the startup is completed and the normal operation control is performed.

FIG. 31 is a flow chart showing the operation of the identification code setting means, the identification code transmitting means, the transmission identification code storing means, the own unit identification number setting means, and the duplicate detection code setting means in the indoor unit. Step S
321 and S322 are identification code setting means, and step S3
23 is an identification code transmitting means, step S324 is a transmission identification code storage means, steps S325 to S326 are own unit identification number setting means, and steps S327 and S32.
Reference numeral 8 shows the operation of the duplicate detection code setting means. In the figure,
When the indoor unit receives the identification code request from the outdoor unit 1 in step S321 after the power is turned on, the indoor unit sets the identification code in step S322, and then in step S323.
In step S, the identification code is transmitted to the outdoor unit 1
At S324, the transmitted identification code is stored and stored in step S3.
Return to 21. The identification code setting process of step S322 is
28, the identification code transmission processing of step S323 is performed in steps S223 and FIG. 28, the identification code storage processing of step S324 is performed in steps 223 to S224 of FIG.
The same as 225. In step S321, the identification code request from the outdoor unit 1 is not received, and the step S325 is performed.
When the number of connected units, the identification number, and the identification code from the outdoor unit 1 are received in step S326, the own unit identification number is set in accordance with the received identification number, and the process returns to step S321. The own unit identification number setting process in step S326 is the same as steps S227 to S229 in FIG. When the duplicated detection code request is received from the outdoor unit 1 in step S327 without receiving the connected number, the identification number and the identification code in step S325, the duplication detection code is set to the number of logical "1" in step S328. It is arbitrarily set to be a constant value m2, for example, by calculation from a random number, a timer count value of a microcomputer, etc., and step S3
At 29, the data is transmitted to the outdoor unit 1, and the process returns to step S321. In the duplication detection code setting process of step S328,
In step S327, the duplicate detection code is set each time the duplicate detection code request is received from the outdoor unit 1. In step S327, the duplication detection code request is not received,
When the start-up completion data is received in 330, the start-up process is completed in step S331, and the operation control shifts to normal operation. If the startup completion data has not been received in step S330, the process returns to step S321. The startup completion data does not have to be special data,
Ordinary operation control data may be used.

In this way, the indoor unit operates in step S3.
In 28, the number of logic "1" is set to a constant value m2 for the duplicate detection code.
Since the indoor unit identification number is not set redundantly, the logic of the duplicate detection code received by the outdoor unit 1 "
The number of 1 "is m2, and if multiple indoor units are set to be duplicated with the same identification number, the number of logic" 1 "of the duplicate detection code received by the outdoor unit 1 will be greater than m2, and the outdoor unit In step S307, the duplicate setting can be detected.

Further, the number m2 of logic "1" of the duplication detection code
By increasing, the probability of duplication detection codes arbitrarily set by all the indoor units, such as random numbers, decreases, and the probability of duplicate detection of the indoor unit identification number can be increased. Here, the logic "1" means that when a plurality of indoor units simultaneously transmit logic "1" and logic "0" as in the embodiments of the multi-type air conditioner according to claim 1 and claim 2, The unit 1 is a code which is set by the receiving circuit 21 so as to receive the logic "1".

Next, another embodiment will be described with reference to FIGS. 32 and 33. FIG. 32 is a block diagram showing a control device for an outdoor unit using one embodiment of the air conditioner.
Reference numeral 4 is a nonvolatile memory that stores the set number of connected indoor units. FIG. 33 is a flowchart showing the operation of the indoor unit connection number setting means, the indoor unit identification number setting means, the connected number, identification number and identification code transmission means, and the indoor unit identification number duplication detection means in the outdoor unit. In FIG. 33, when the outdoor unit determines that the number of connected indoor units is stored in the nonvolatile memory 214 in step S401 after the power is turned on,
The indoor unit connection number setting process of step S402 is not performed, but the indoor unit identification number setting process of step S403, the connected unit number, the identification number and the identification code transmission process of step S404, and the indoor unit identification number duplication detection process of step S405 are performed. If no overlap is detected, the startup is completed in step S406 and the normal operation control is performed. If duplicates are detected, the process returns to step S402. If it is determined in step S401 that the number of connected indoor units is not stored in the nonvolatile memory 214,
The process from the indoor unit connection number setting process of step S402 to the indoor unit identification number duplication detection process of step S405 is performed, and startup is completed at step S406, and normal operation control is entered. The indoor unit connection number setting process in step S402 is shown in FIG. 30 and the indoor unit identification number setting process in step S403 is shown in FIG.
In step S302, the connection number, identification number and identification code transmission processing in step S404 is performed in step S303 in FIG.
The indoor unit identification number duplication detection processing in step S405 is the same as in step S304 to step S308 in FIG.

Next, the operation of the air conditioner when the number of connected indoor units is once set and the number of connected indoor units is changed and the power is turned on again will be described. First, a case will be described in which more indoor units are connected than the number of connected indoor units stored in the nonvolatile memory 214. After the power is turned on, the outdoor unit 1 is step S4.
In 01, since it is determined that the number of connected indoor units is stored in the nonvolatile memory 214, the process of setting the number of connected indoor units in step S402 is not performed,
Although the indoor unit identification number setting processing of 03 is executed, since the number of indoor units is large, the number of logical "1" that is larger than the stored number of connected indoor units is received. In this case, the number of received logical "1" is set as the number of connected indoor units, the indoor unit identification number setting process of step S403 is performed again, and then the number of connected units, identification number and identification code transmission process of step S404, step S
405 indoor unit identification number duplication detection processing is performed,
If no overlap is detected, the start-up is completed in step S406 and the normal operation control is performed. If duplicates are detected, the process returns to step S402.

Next, the case where the number of indoor units connected is smaller than the number of connected indoor units stored in the nonvolatile memory 214 will be described. Since the outdoor unit 1 determines that the number of connected indoor units is stored in the nonvolatile memory 214 in step S401 after the power is turned on, the indoor unit connected number setting process of step S402 is not performed, and the indoor unit of step S403 is not executed. Although the unit identification number setting process is executed, the number of indoor units is small, so the number of logical units is smaller than the stored number of connected indoor units.
1 "is continuously received. When this state continues until the transmission and reception of the identification code is performed n3 times, the indoor unit connection number setting process of step S402 is performed, and step S4
After redoing the indoor unit identification number setting process of 03,
The number of connected units, the identification number and the identification code transmission process in step S404, and the indoor unit identification number duplication detection process in step S405 are performed. If no duplication is detected, step S404 is performed.
At 406, the startup is completed and the operation shifts to the normal operation control. If duplicates are detected, the process returns to step S402. In this way, even if the number of connected indoor units connected to the unit once installed is changed, it is possible to reliably set the number of connected indoor units.

Next, another embodiment will be described with reference to FIGS. FIG. 34 is a block diagram showing a control device for an indoor unit using one embodiment of an air conditioner, and in FIG.
Is a non-volatile memory that stores the set indoor unit identification number. FIG. 35 is a flowchart showing the operations of the identification code setting means, the identification code transmitting means, the transmission identification code storage means, the own unit identification number setting means, and the duplicate detection code setting means in the indoor unit. Step S5
01 to S504 are identification code setting means, and step S50
5, S506 is the identification code transmitting means, step S507
Is the transmission identification code storage means, and steps S508, S50
Reference numeral 9 designates its own unit identification number setting means, step S51.
0 and S511 indicate the operation of the duplicate detection code setting means. In the figure, after the indoor unit is powered on, step S50
When the identification code request from the outdoor unit 1 is received in 1 and it is determined in step S502 that the identification number of the own unit is not stored in the nonvolatile memory 224, a new identification code is created in step S503. , Step S
At 504, the identification code to be transmitted is set. Step S
If it is determined in 502 that the identification number of its own unit is stored in the non-volatile memory 224, the identification code new creation processing in step S503 is not performed, and the identification number stored in the non-volatile memory 224 is unique. In step S504, a uniquely determined identification code is set. For example, when the stored identification number is 1, only bit position 1 is logical "1".
In case of identification number 2, only bit position 2 is logical "1"
... In case of identification number i, only bit position i is logical "1"
The identification code is set so that In this case, in the new creation processing of the identification code in step S503, the code is created such that the bit positions 1 to i are logical "0" and the bit positions i + 1 and subsequent are logical "1". Step S5
After the identification code is set in 04, when the transmission timing comes in step S505, the identification code is transmitted to the outdoor unit 1 in step S506, and step S507.
The identification code transmitted in step S501 is stored and the process returns to step S501. Processing when the identification code request from the outdoor unit 1 is not received in step S501 (step S50)
8 to S514) are the same as steps S325 to S331 in FIG.

As described above, when the indoor unit stores the identification number of its own unit in the non-volatile memory 224, the identification code is uniquely set for the stored identification number and transmitted to the outdoor unit. For example, when the outdoor unit again sets the indoor unit identification number when the power is turned off and then turned on again, the identification number of each indoor unit is not changed.

FIG. 36 shows that when the number of indoor units connected to the outdoor unit 1 is three (A) 2 to (C) 4, the indoor unit does not store the identification number of its own unit in the nonvolatile memory 224. Timing chart showing the operation in the case, FIG.
7 is a timing chart showing the operation when the indoor unit stores the identification number of its own unit in the nonvolatile memory 224. For example, if the maximum number of indoor units connected is four, the identification code when the identification number is stored in the non-volatile memory 224 is such that the bit positions 1 to 4 are logical "
1 ”, the identification code when the identification number is not stored in the non-volatile memory 224 uses bit position 5 or later, and the identification code is stored when the identification number is not stored in the non-volatile memory 224. Based on the signal 505 received by the outdoor unit 1, the identification number of the indoor unit (C) 4 which has transmitted the identification code / signal 504 with the bit number 5 as logical “1” is 1 and the bit number. The identification number of the indoor unit (A) 2 which has transmitted the identification code / signal 502 with 7 as the logical “1” is 2, and the bit number 10
If the identification number of the indoor unit (B) 3 that has transmitted the identification code / signal 503 is set to 3 as "1", the identification code transmission / reception when the power is turned on again is as shown in FIG.
Based on the signal 515 received by the outdoor unit 1, the identification number of the indoor unit (C) 4 that transmitted the identification code / signal 524 with bit number 1 as logical “1” is 1 and the bit number 2 is
Of the indoor unit (A) 2 which has transmitted the identification code / signal 512 with "1" as the logic "1", and the indoor unit (B) 3 which has transmitted the identification code / signal 513 with the bit number 3 as the logic "1" Since the identification number is set to 3, it does not change from the setting at the time of installation. Therefore, for example, when an abnormality occurs in the indoor unit, the identification number of the abnormal unit is displayed on the remote controller or the like, the fan of the corresponding indoor unit is controlled at the time of self-diagnosis, or each LED is provided on the board. Even when the identification number set in the indoor unit is displayed to notify the abnormality occurrence unit, the identification number of the unit, and the details of the abnormality, the identification number of the indoor unit changes each time the power is reset. It does not cause confusion when servicing.

A case where this embodiment is applied to an air conditioner in which the number of indoor units connected to the outdoor unit is known will be described with reference to FIG. Since the number of indoor units is known, the same is true when it is determined in step S401 that the number of connected indoor units is stored in the nonvolatile memory 214, and the indoor unit connected number setting process of step S402 is not performed. For example, if the number of indoor units is set to one, the
If more than one unit is connected, the outdoor unit 1 performs the indoor unit identification number setting process of step S403 after power is turned on, but it receives a logic "1" that is larger than the number of connected indoor units (1 unit). . In this case, since the setting is erroneous, it is possible to prompt the correction by terminating the start-up process and notifying the erroneous setting using a remote controller, a display means such as an LED on the substrate, or the like. If the same number of logical "1" is received for the number of connected indoor units (1 unit) in the indoor unit identification number setting process of step S403, the indoor unit identification number setting process of step S403, the connected number of units of step S404 The identification number / identification code transmission process and the indoor unit identification number duplication detection process in step S405 are performed. If no duplication is detected, the startup is completed in step S406 and the normal operation control is performed. If duplicates are detected, the process returns to step S402. If the known number of connected indoor units is not 1,
In the indoor unit identification number setting process of step S403, when a logical "1" that is larger than the number of connected indoor units or a logical "1" that is smaller than the connected number of indoor units is received, the setting is erroneous. After the start-up process is completed, it is possible to notify the user of the erroneous setting by using a remote controller, a display device such as an LED on the board, and prompt correction. Here, the number of connected indoor units stored in the outdoor unit is programmed in advance or stored in a nonvolatile memory in advance. Alternatively, it may be set by a switch or the like. In this way, when applied to an air conditioner with a known number of indoor units, if the startup time is short and the number of connected indoor units is incorrect,
The serviceability can be improved by surely detecting and notifying by a display means or the like.

Even if the number of indoor units is unknown, if the maximum number of connected units is fixed, and if the number of connected indoor units exceeds the maximum number of connected units, an incorrect connection is similarly detected and displayed. It is possible to notify by means etc., and the serviceability can be improved.
