Description

  Embodiments of the present invention relate to an entire building air conditioning system that air-conditions a plurality of areas of a house with one air conditioning unit.

  Conventionally, in a whole building air conditioning system, there is a remote controller for operating the control contents of an air conditioning unit in which a master unit is installed in one area and a slave unit is installed in each other area. The master unit is a device that can instruct air conditioning for all areas. In addition, the slave unit is a device that can set the air conditioning of the installed area as a responsible area and can instruct the air conditioning of the responsible area. In this case, the slave unit transmits the setting content input by the user to the master unit. Then, the master unit controls the air conditioning unit according to the setting content received from the slave unit. Thereby, the user can control the air conditioning of the area in which the child device is installed by operating the child device without operating the parent device.

  In such a configuration, it is necessary to correctly set the correspondence relationship between the area where the air conditioning control is performed by the operation of each slave unit and the area where the slave unit is actually installed in advance as an initial setting. If this initial setting is not performed correctly, for example, when the user tries to control the air conditioning in a certain area and operates a slave unit installed in that area, the air conditioning in another area is erroneously controlled. This is because a situation occurs.

  Therefore, in the conventional configuration, when performing the initial setting, the user first determines which area the control area controlled by the air conditioning unit is actually assigned, that is, in which room the air conditioning duct of the air conditioning unit is actually assigned. Know if they are connected. This control area is grasped by, for example, arranging a person who operates the main unit and a person who confirms the air-conditioning operation in each area separately, and operating the main unit to actually operate the air conditioning unit. It was. Then, the user operates the parent device and the child device, and associates and stores each child device and each area in the parent device, thereby setting the planned installation area, that is, the responsible area for each child device, , And set up each handset according to the assigned area.

  However, in such a conventional configuration, each slave unit is actually installed in the assigned area after the assigned area is set. For this reason, the user sometimes installed the slave unit in a different area by mistake. Further, as described above, at least two workers are required to grasp the control area of the air conditioning unit, and the workers must check the air conditioning operation by operating the master unit one by one. Therefore, it took time and effort to grasp the control area of the air conditioning unit.

JP 2006-143275 A

  The present invention has been made in view of the above circumstances, and an object thereof is to save labor in the initial setting, and an area where air conditioning control is performed by each slave unit and a zone where the slave unit is actually installed. The purpose is to provide a building-wide air conditioning system that can reduce errors in correspondence.

(Claim 1)
The entire building air-conditioning system according to claim 1 is an air-conditioning unit capable of individually air-conditioning a plurality of areas, a parent machine that instructs the air-conditioning unit to control contents related to air-conditioning of each area, and communication with the parent machine. And a plurality of slave units that are installed in each of the areas and that transmit control contents input from a user to the master unit. The slave unit has an environment information acquisition unit that acquires environmental information of the area where the slave unit is installed. The master unit operates the air conditioning unit in cooperation with each slave unit as an initial setting for linking each slave unit and each zone in which each slave unit is installed. Environment change processing for changing the environment of the one area by air-conditioning for one of the areas, and handset specifying processing for specifying the handset whose environment information acquired by the environment information acquisition unit has changed among the handset And an area allocation process for allocating the one area air-conditioned in the environment change process to an installation area of the slave unit specified in the slave unit specifying process.

  That is, in the conventional configuration, after the user associates each slave unit and the area where the slave unit is scheduled to be installed, the user installs each slave unit in each associated region. That is, in the conventional configuration, when the user takes the handset to each area, the handset and the area are already associated with each other. Therefore, the situation where the user installed the cordless handset in a different area by mistake could occur. On the other hand, in this configuration, after each child device is installed in each area, the association between each child device and the area where the child device is actually installed is performed. Therefore, it is possible to suppress the occurrence of an error in the correspondence between the area where air conditioning control is performed by each slave unit and the area where the slave unit is actually installed.

  Furthermore, according to this configuration, unlike the conventional configuration, when the user takes the slave unit to each area, the slave unit and the area are not yet associated with each other. Therefore, the user can install each slave unit in an arbitrary area without being aware of the correspondence between each slave unit and the area. Moreover, according to this structure, the subunit | mobile_unit currently installed in each area is automatically identified by the main | base station. Therefore, the user does not need to grasp the control area of the air conditioning unit when performing the initial setting as in the conventional configuration. As a result, the workability at the time of installation of each slave unit, that is, the initial setting can be improved, and the labor required for the user's initial setting can be saved. As described above, according to this configuration, in the initial setting, it is possible to save the user's work, and the correspondence between the area where the air conditioning control is performed by each slave unit and the area where the slave unit is actually installed Mistakes can be reduced.

(Claim 2)
The whole building air conditioning system of Claim 2 WHEREIN: The said subunit | mobile_unit has at least any one of a temperature sensor, an atmospheric | air pressure sensor, or a humidity sensor as said environmental information acquisition part. Temperature, atmospheric pressure, and humidity are environmental information that is easily changed by air conditioning. For this reason, since the slave unit detects at least one of temperature, atmospheric pressure, and humidity, the slave unit can more accurately detect changes in the surrounding environment caused by the environmental change process, As a result, more accurate initial setting can be performed.

  Incidentally, temperature and pressure are more susceptible to air conditioning than humidity. Therefore, it is preferable that the subunit | mobile_unit has at least any one of a temperature sensor or an atmospheric | air pressure sensor as an environmental information acquisition part. According to this, compared with the case where the subunit | mobile_unit has only a humidity sensor, a more exact initial setting can be performed.

(Claim 3)
Here, it is assumed that one slave unit is installed in each area, and in the environment change process, air conditioning is performed for only one area. Nevertheless, the specification of two or more slave units in the slave unit identification process means that a plurality of identified slave units are installed in the same area where air conditioning has been performed, or It is considered that the environment has changed due to factors other than air conditioning due to, for example, the opening and closing of doors and windows in other areas where no air conditioning is performed.

  Furthermore, even though air conditioning is performed for one area in the environmental change process, no slave unit is identified even after a predetermined period of time in the slave unit identification process. In the area where the cordless handset is not installed or air-conditioning is performed, the air-conditioning air has flowed out to the outside due to the opening of doors and windows, etc. The situation is considered. In any case, since the one-to-one correspondence between each handset and each area cannot be specified, the assignment of the handset to the area fails.

  Therefore, in the entire building air conditioning system according to claim 3, when the master unit specifies two or more slave units in the slave unit specifying process, or when a single slave unit is not specified even after a predetermined period of time, Without performing the area allocation process, the initial setting is performed again for an area whose environment has been changed in the environment change process. According to this, when the association between the area where the child device is installed and the child device cannot be specified for some reason, the parent device automatically performs the initial setting for the area again. Thereby, even if it is a case where initial setting fails, it is not necessary for a user himself / herself to link a subunit | mobile_unit and an area, As a result, a user's effort can be saved.

(Claim 4)
The master unit executes the processes after the initial environment storage process on condition that all changes in the environment information received from the slave units are stabilized within a predetermined range. According to this, initial setting can be performed in a state where influences other than air conditioning by the air conditioning unit are eliminated as much as possible. Therefore, more accurate initial setting can be performed.

Hereinafter, an embodiment will be described with reference to the drawings.
A whole building air conditioning system 10 shown in FIG. 1 is provided in a house 100. The house 100 has a plurality of areas. This area is not limited to living rooms and bedrooms, but may include bathrooms, toilets, entrances and atriums. In the present embodiment, for simplicity of explanation, the house 100 having four areas 1 to 4 will be described as an example. However, the number of areas and the configuration thereof, that is, the number of rooms and the structure thereof are not limited to those of the house 100. .

  The entire building air conditioning system 10 air-conditions a plurality of areas in the house 100, in this case, four areas 1 to 4 by one air conditioning unit 20. In this embodiment, the entire building air conditioning system 10 includes an air conditioning unit 20, air conditioning ducts 111 to 114, a remote control parent device 30 (hereinafter referred to as a parent device 30), and a remote control child device 40 (hereinafter referred to as a child device 40). I have.

  The air conditioning unit 20 is configured by a known heat exchanger such as a heat pump having, for example, the indoor unit 21 shown in FIG. 1 and an outdoor unit (not shown). The air conditioning unit 20 uses the zones 1 to 4 as air conditioning control zones. Each air-conditioning duct 111-114 is provided corresponding to each area 1-4, and has connected the indoor unit 21 of each air-conditioning unit 20, and each area 1-4. The air conditioning unit 20 has a plurality, in this case, four on-off valves 221 to 224. Each of the on-off valves 221 to 224 corresponds to each of the areas 1 to 4 and is provided in the middle or end of each of the air conditioning ducts 111 to 114, and opens and closes each of the air conditioning ducts 111 to 114.

  The air conditioning unit 20 performs air conditioning in each of the areas 1 to 4 as follows, for example. That is, the air conditioning unit 20 takes in the air in each of the areas 1 to 4, that is, the inside air, exchanges heat with the indoor unit 21, and takes in outside air from the outside of the house 100 through a filter (not shown). Then, the air conditioning unit 20 mixes the heat exchanged inside air and outside air, thereby adjusting the humidity and temperature to generate air that has been conditioned. And the air-conditioning unit 20 selectively supplies the air by which air conditioning was performed with respect to each area 1-4 by carrying out open / close control of each on-off valve 221-224. In this way, the air conditioning unit 20 performs air conditioning for each of the areas 1 to 4.

  The air conditioning unit 20 can set the air conditioning target temperature for each of the areas 1 to 4. In this case, the air conditioning unit 20 adjusts the opening and closing and the opening degree of the on-off valves 221 to 224 according to the difference between the indoor temperature of each section 1 to 4 and the air conditioning target temperature, and supplies air to each section 1 to 4. Adjust the amount. Thereby, the air-conditioning unit 20 keeps the room temperature of each area 1-4 to the set air-conditioning target temperature. In this way, the air conditioning unit 20 is configured to be individually air conditioned for each of the areas 1 to 4.

  In the present embodiment, the air conditioning unit 20 includes one master unit 30 and four slave units 40 corresponding to the number of sections 1 to 4 as shown in FIG. In the following description, when each child device 40 is distinguished, it is indicated as child device 40 (A), child device 40 (B), child device 40 (C), and child device 40 (D). Each cordless handset 40 (A) to (D) has a unique identification ID set so as not to overlap each other.

  In the case of this embodiment, one of the four slave units 40 is incorporated in the master unit 30. That is, the slave unit 40 (A) of the four slave units 40 is also used as the master unit 30. Each child device 40 is configured to be able to communicate with the parent device 30 wirelessly or by wire. The base unit 30 is installed in an arbitrary area among the areas 1 to 4. The slave units (B) to (D) other than the slave unit 40 (A) incorporated in the master unit 30 are installed one by one in an area where the master unit 30 and the slave unit 40 (A) are not installed. Each cordless handset 40 receives setting contents such as an air conditioning target temperature from the user, and transmits the inputted setting contents to the parent machine 30.

  The base unit 30 is configured to be communicable with the air conditioning unit 20, and transmits the setting contents such as the air conditioning target temperature received from each slave unit 40 to the air conditioning unit 20. Thereby, the main | base station 30 instruct | indicates the control content regarding the air conditioning of each area 1-4 with respect to the air conditioning unit 20. FIG. And according to the control content received from the main | base station 30, the air conditioning unit 20 air-conditions with respect to each area 1-4.

  The subunit | mobile_unit 40 has the temperature sensor 41, the atmospheric | air pressure sensor 42, the humidity sensor 43, the operation part 44, the display part 45, the communication part 46, and the control part 47 as shown in FIG. The temperature sensor 41 detects the temperature around the child device 40, that is, the temperature of the area where the child device 40 is installed. The atmospheric pressure sensor 42 detects the atmospheric pressure around the child device 40, that is, the air pressure in the area where the child device 40 is installed. The humidity sensor 43 detects the humidity around the child device 40, that is, the humidity of the area where the child device 40 is installed. The temperature sensor 41, the atmospheric pressure sensor 42, and the humidity sensor 43 are the environment information around the child device 40, that is, the environment in which the temperature, pressure, humidity, and the like of the area are acquired as the environment information of the area where the child device 40 is installed. Functions as an information acquisition unit.

  The operation unit 44 receives an input operation from the user, and includes, for example, a mechanical switch, an electric touch switch, or the like. The display unit 45 is a liquid crystal panel or the like, for example, and displays various information such as input contents from the user, current setting contents, and environmental information around the slave unit 40 detected by the sensors 41 to 43. The communication unit 46 has a function of performing wireless or wired communication with the parent device 30, and the detection results of the sensors 41 to 43 and the setting information input by the operation unit 44 with respect to the parent device 30. Etc.

  The control unit 47 is configured mainly with a microcomputer having a storage area 472 such as a CPU 471, ROM, RAM, and rewritable flash memory, for example, and controls the entire slave unit 40. That is, the control unit 47 controls operations of the temperature sensor 41, the atmospheric pressure sensor 42, the humidity sensor 43, the operation unit 44, the display unit 45, and the communication unit 46.

  As shown in FIG. 4, the parent device 30 includes a temperature sensor 41, an atmospheric pressure sensor 42, a humidity sensor 43, an operation unit 44, and a display unit 45 as functions of the child device 40. In addition, the master unit 30 has a control unit 31. The control unit 31 is mainly configured by a microcomputer having a storage area 312 such as a CPU 311, a ROM, a RAM, and a rewritable flash memory, for example, and controls the entire master unit 30 and the air conditioning unit 20. ing. In this case, the base unit 30 is connected to the air conditioning unit 20 so as to be communicable, for example, by a communication line. In addition, the main | base station 30 may be connected with the air conditioning unit 20 by radio | wireless communication so that communication is possible.

  The storage area 312 stores various control programs for controlling the air conditioning unit 20 and an initial setting program for performing initial settings. The initial setting program includes an area where air conditioning control is performed by operating each of the slave units 40 (A) to (D), and a zone 1 to 4 where the slave units 40 (A) to (D) are actually installed. It is a program for setting correspondence. By performing initial settings, the parent device 30 associates and stores each child device 40 and each of the areas 1 to 4 in which each child device 40 is actually installed.

  That is, the control unit 31 executes the initial setting program in the CPU 311 so that the initial environment storage processing unit 32, the environment change processing unit 33, the slave unit specifying processing unit 34, the area allocation processing unit 35, etc. Realize. The initial environment storage processing unit 32, the environment change processing unit 33, the slave unit identification processing unit 34, the area allocation processing unit 35, and the like may be realized in hardware as an integrated circuit integrated with the control unit 31, for example. Good. The initial environment storage processing unit 32, the environment change processing unit 33, the child device identification processing unit 34, and the area allocation processing unit 35 constitute a function as the parent device 30.

  The initial environment storage processing unit 32 executes initial environment storage processing. The initial environment storage process is a process of storing the current environment information acquired from each slave unit 40 as the initial environment information or storing it in each slave unit 40. The environment change processing unit 33 executes environment change processing. The environment change process is executed after the initial environment storage process, and the air conditioning unit 20 is operated to perform air conditioning for one of the areas 1 to 4, that is, the environment of that one area, that is, temperature, atmospheric pressure, or This is a process for changing at least one of the humidity.

  The subunit | mobile_unit identification process part 34 performs a subunit | mobile_unit identification process. The slave unit specifying process is executed after the environmental change process. Among each slave unit 40, the environmental information acquired by the environmental information acquisition unit, that is, the temperature detected by the temperature sensor 41, and the atmospheric pressure sensor 42 are detected. A slave unit in which either the atmospheric pressure or the humidity detected by the humidity sensor 43 has changed is specified. And the area allocation process part 35 performs an area allocation process. The area allocation process is executed after the slave unit specifying process, and is a process of allocating one area air-conditioned in the environment change process to the slave unit installation area specified by the slave unit specifying process.

  Specifically, base unit 30 executes the control content shown in FIG. 5 at the time of initial setting. This initial setting is started, for example, when the user performs a predetermined operation on the operation unit 44 of the parent device 30. In addition, when initial setting is performed, each subunit | mobile_unit 40 shall already be installed in each area 1-4 as shown in FIG. Further, it is assumed that the air conditioning unit 20 is not operating when the initial setting is executed.

  When the initial setting is started, first, base unit 30 sets the number of areas N in step S11 shown in FIG. The number of areas N is set by, for example, the user operating the operation unit 44 of the master unit 30 and inputting the number of areas 1 to 4 of the house 100 targeted for the entire building air conditioning system 10, in this case “4”. To do.

  Next, in step S12, base unit 30 sets the area to be allocated as area (N). N is a variable, and the number of areas, in this case “4” is the maximum value. The area (N) is changed every time one slave unit 40 is allocated. In this case, the parent device 30 assigns each child device 40 in the order of area 4, area 3, area 2, and area 1.

  In step S <b> 13, base unit 30 receives the detection results of sensors 41, 42, and 43 from each handset 40. Thereby, the main | base station 30 acquires the environmental information of the areas 1-4 in which each subunit | mobile_unit 40 is installed, ie, temperature, atmospheric | air pressure, and humidity. In this case, the parent device 30 may request each child device 40 to transmit the detection results of the sensors 41, 42, and 43. Further, when the power of each slave unit 40 is turned on, the detection result of each sensor 41, 42, 43 may be automatically transmitted from each slave unit 40 to the master unit 30.

  Next, in step S <b> 14, base unit 30 determines whether or not the environmental information of each zone 1 to 4 acquired in step S <b> 13 is stable within a certain range. For example, as shown in FIG. 6, the base unit 30 determines that the environment of the area is stable when the environmental information, for example, the temperature change rate during a predetermined period is less than ΔT1. . If there is an area where the environment is not stable in any one of areas 1 to 4 (NO in step S14 in FIG. 5), base unit 30 waits until the environments of all areas 1 to 4 are stabilized. In this case, whether or not the environment is stable may be determined by using at least one of temperature, atmospheric pressure, and humidity as environmental information, but may be used in combination.

  If base unit 30 determines that the environment in each of areas 1 to 4 is stable (YES in step S14), it executes an initial environment storage process in step S15. Thereby, the main | base station 30 memorize | stores the initial environmental information of each area 1-4, ie, the initial environmental information in the state where the air-conditioning unit 20 is not operating. In addition, the main | base station 30 may memorize | store the initial environment information of each subunit | mobile_unit 40 in each subunit | mobile_unit 40, without memorize | storing itself.

  Next, base unit 30 executes environment change processing in step S16. In this case, for example, if the allocation target area is area 1, base unit 30 controls air conditioning unit 20 to perform air conditioning of area 1. Then, as shown in FIG. 7, the air conditioning unit 20 opens the on-off valve 221 corresponding to the area 1 and supplies air that has been air-conditioned to the area 1. Thereby, the environment, that is, the temperature, the atmospheric pressure, and the humidity of the area 1 in which the air conditioning is performed changes.

  Next, base unit 30 executes a handset specifying process in step S17. Thereby, the subunit | mobile_unit 40 from which the surrounding environment changed is pinpointed. In this case, in the initial environment storage process in step S15, if the parent device 30 stores the initial environment information, the parent device 30 can specify the child device 40 as follows.

  That is, in this case, the base unit 30 sets a threshold value ΔT2 for use in specifying the handset 40. The threshold value ΔT2 is, for example, a threshold value of the change rate of the current environmental information with respect to the initial environmental information stored in the initial environmental information processing. For example, after the start of the initial setting, the parent device 30 acquires environment information from each child device 40 as needed or periodically. Then, base unit 30 compares the acquired current environment information with the initial environment information stored in the initial environment storage process, and as shown in FIG. 8, the change rate of the environment information exceeds threshold ΔT2. By detecting the child device 40, the child device 40 whose surrounding environment has changed is specified.

  Further, in the initial environment storage process of step S15, if each child device 40 stores the initial environment information, the parent device 30 can specify the child device 40 as follows. That is, the parent device 30 sets a threshold value ΔT2 common to each child device 40 for each child device 40. The subunit | mobile_unit 40 acquires environmental information at any time or regularly by each sensor 41-43, for example after the start of initial setting. And the subunit | mobile_unit 40 compares the acquired present environmental information with the initial environmental information memorize | stored by the initial environment memory | storage process, and as shown in FIG. 8, the change rate of environmental information exceeded threshold value (DELTA) T2. In this case, a signal indicating that the change rate has exceeded the threshold value ΔT2 is transmitted to the parent device 30. When receiving a signal indicating that the rate of change has exceeded the threshold value ΔT2 from the slave unit 40, the master unit 30 identifies the slave unit 40 that has transmitted the signal.

  Next, base unit 30 determines whether or not there is only one slave unit 40 identified in step S17 in step S18 of FIG. That is, the parent device 30 determines whether or not two or more child devices 40 have been specified in the child device specifying process in step S17, and whether or not one child device 40 has been specified even after a predetermined period has elapsed. Determine whether.

  Here, it is assumed that each slave unit 40 is installed in each of the areas 1 to 4, and in the environment change process in step S16, air conditioning is performed for only one area. Nevertheless, the fact that two or more slave units are specified in the slave unit specifying process in step S17, that is, for example, as shown in FIG. The fact that the rate has changed beyond the threshold value ΔT2 means that the specified plurality of slave units 40 are installed in the same area where air conditioning has been performed or in other areas where air conditioning has not been performed, for example, It is thought that the environment has changed due to factors other than air conditioning, such as the opening of doors and windows to allow outside air to enter.

  Further, although one area is being air-conditioned, one slave unit is not specified in the slave unit specifying process in step S17, that is, for example, in all the slave units 40 as shown in FIG. The change rate of the surrounding environmental information does not exceed the threshold value ΔT2, which means that no handset 40 is installed in the air-conditioned area, or in the air-conditioned area, for example, a door or It is thought that the environment has changed due to factors other than air conditioning, such as the open air entering the window. In any case, since the one-to-one correspondence between each child device 40 and each of the areas 1 to 4 cannot be specified, the assignment of the child device 40 to the area fails.

  Therefore, when the number of the slave units 40 specified in step S17 in FIG. 5 is other than one (NO in step S18), the master unit 30 controls the air conditioning unit 20 in step S23 to control the environment in step S16. Stop individual air conditioning for one area that was changed. Thereafter, the base unit 30 displays a caution on the display unit 45 of the base unit 30 and the slave unit 40 as shown in step S24. This caution display eliminates influences other than the influence of air conditioning by the air conditioning unit 20 as much as possible, for example, in each of the areas 1 to 4, such as whether windows and doors are closed, and whether other air conditioning equipment is used. It is a display for prompting.

  Thereafter, base unit 30 returns the process to step S13. Thereby, the base unit 30 does not perform the area allocation process in step S19, but again performs the initial process for the area in which the environment has been changed in the environment change process in step S16, that is, the area to which the slave unit 40 is allocated. Set up.

  On the other hand, when there is one slave unit 40 identified in step S17 (YES in step S18), base unit 30 executes area allocation processing in step S19. Thereby, the main | base station 30 allocates one area which air-conditioned separately by the environmental change process of step S16 to the installation area of the subunit | mobile_unit 40 identified by the subunit | mobile_unit identification process of step S17. Next, the main | base station 30 controls the air conditioning unit 20 in step S20, and stops the individual air conditioning with respect to one area performed by the environmental change process of step S16.

  Next, in step S21, base unit 30 subtracts 1 from the number of areas N, and changes the area to be allocated. The master unit 30 repeats steps S12 to S22 until the number N of areas becomes 0, and assigns the corresponding slave units 40 (A) to (D) for all the areas 1 to 4 as shown in FIG. When the number of areas N becomes 0 (YES in step S22 in FIG. 5), the parent device 30 determines that the assignment of the child devices 40 has been completed for all the areas 1 to 4, and ends a series of processing ( End).

  Incidentally, in the case of the present embodiment, the allocation result of each slave unit 40 for each of the areas 1 to 4 is stored in the storage area 312 of the master unit 30 as shown in FIG. In this case, each slave unit 40 has an identification ID unique to each slave unit 40. When the user operates the child device 40, the child device 40 that has received the operation transmits its own identification ID to the parent device 30 together with the input operation command. And the main | base station 30 performs air-conditioning control about the areas 1-4 allocated to received identification ID based on the received operation command.

  According to the embodiment described above, the parent device 30 cooperates with each child device 40 as an initial setting for associating each child device 40 with each of the areas 1 to 4 where each child device 40 is installed. The initial environment storage process, the environment change process, the slave unit specifying process, and the area allocation process are sequentially executed. According to this, after each subunit | mobile_unit 40 (A)-(D) is installed in each area 1-4, each subunit | mobile_unit 40 (A)-(D) and its subunit | mobile_unit 40 (A)-(D) Is associated with the areas 1 to 4 in which they are actually installed. Accordingly, the correspondence relationship between the areas 1 to 4 where the air conditioning control is performed by each of the slave units 40 (A) to (D) and the areas 1 to 4 where the slave units 40 (A) to (D) are actually installed. No mistakes will occur.

  Furthermore, according to the present embodiment, when the user takes the slave units 40 (A) to (D) to each of the areas 1 to 4, the respective slave units 40 (A) to (D) and the respective areas are still in use. It is the state where the stringing with 1-4 is not carried out. Therefore, the user can connect each slave unit 40 (A) to (D) to any one of the zones 1 to 4 without being aware of the correspondence between each slave unit 40 (A) to (D) and each zone 1 to 4. 4 can be installed.

  Moreover, according to this embodiment, the subunit | mobile_unit 40 (A)-(D) installed in each area 1-4 is automatically specified by the main | base station 30. FIG. Therefore, the user does not need to grasp the control area of the air conditioning unit 20 when performing the initial setting. As a result, the workability at the time of installation of each of the slave units 40 (A) to (D), that is, the initial setting can be improved, and the labor required for the user's initial setting can be saved. As described above, according to the present embodiment, in the initial setting, the user's work can be saved and the areas 1 to 4 where the air conditioning control is performed by each of the slave units 40 (A) to (D) are actually performed. In addition, it is possible to reduce errors in correspondence with the areas 1 to 4 where the slave units 40 (A) to (D) are installed.

  In the entire building air conditioning system 10, the slave units 40 (A) to (D) have at least one of the temperature sensor 41, the atmospheric pressure sensor 42, and the humidity sensor 43 as an environment information acquisition unit. Temperature, atmospheric pressure, and humidity are environmental information that is easily changed by air conditioning. For this reason, the subunit | mobile_unit 40 (A)-(D) arises by an environmental change process because the subunit | mobile_unit 40 (A)-(D) detects at least any one of temperature, atmospheric | air pressure, or humidity. In addition, changes in the surrounding environment can be detected more accurately, and as a result, a more accurate initial setting can be performed.

  Incidentally, temperature and pressure are more susceptible to air conditioning than humidity. Therefore, it is preferable that the subunit | mobile_unit 40 (A)-(D) has at least any one of the temperature sensor 41 or the atmospheric | air pressure sensor 42 as an environmental information acquisition part. According to this, compared with the case where the subunit | mobile_unit 40 (A)-(D) has only the humidity sensor 43, a more exact initial setting can be performed.

  In addition, when the master unit 30 specifies two or more slave units in the slave unit specifying process shown in step S17 of FIG. 5 or when a single slave unit is not specified even after a predetermined period of time, the master unit 30 performs step S19. Without performing the area allocation process, the initial setting is performed again for the area (N) whose environment has been changed in the environment change process in step S16. According to this, when it is not possible to specify the association between the areas 1 to 4 where the slave units 40 (A) to (D) are installed and the slave units 40 (A) to (D) due to some factors, The base unit 30 automatically performs the initial setting for the areas 1 to 4 again. Thereby, even if it is a case where initialization is unsuccessful, it is not necessary for the user himself / herself to associate the slave units 40 (A) to (D) with the areas 1 to 4, and as a result, the user's trouble is saved. Can do.

  In addition, the master unit 30 performs the steps subsequent to the initial environment storage process shown in step S15 of FIG. 5 on the condition that all changes in the environment information received from the slave units 40 (A) to (D) are stabilized within a predetermined range. Execute the process. According to this, initial setting can be performed in a state where influences other than air conditioning by the air conditioning unit 20 are eliminated as much as possible. Therefore, more accurate initial setting can be performed.

The embodiment of the present invention is not limited to the above-described embodiment and can be variously modified and extended without departing from the gist thereof.
For example, in the above embodiment, the slave unit 40 (A) is built in the master unit 30, but the slave unit 40 (A) and the master unit 30 may be configured separately.

  In the above embodiment, the initial setting is configured to perform the environment change process shown in step S16 of FIG. However, the present invention is not limited to this. For example, when the target area N = 1, that is, when the number of unallocated areas becomes 1, the remaining one area is replaced with the remaining one slave unit. For example, a configuration of 40 may be used. According to this, the number of areas where the environment change process is performed can be reduced by one. Therefore, the time required for the initial setting can be shortened.

  Moreover, in the said embodiment, the main | base station 30 memorize | stores the result which tied each subunit | mobile_unit 40 (A)-(D) and each area 1-4, and each subunit | mobile_unit 40 is with the input operation command. It is configured to transmit its own identification ID to the parent device 30. However, the present invention is not limited to this, and may be configured as shown in FIG. 13, for example. That is, in the example of FIG. 13, each child device 40 stores its own assigned areas 1 to 4 that are associated with each other. In this case, when an operation is input to the child device 40 by the user, the child device 40 that has received the input transmits information regarding its own assigned areas 1 to 4 to the parent device 30 together with the input operation command. And the main | base station 30 performs air-conditioning control about the received areas 1-4 based on the received operation command. Also by this, the same operation effect as the above-mentioned embodiment is obtained.

  In the drawings, 10 is an entire building air conditioning system, 20 is an air conditioning unit, 30 is a master unit, 40 is a slave unit, 41 is a temperature sensor (environmental information acquisition unit), 42 is an atmospheric pressure sensor (environmental information acquisition unit), and 43 is a humidity sensor.
