After a predetermined period of time has elapsed from the time when the control of the damper (40) corresponding to the first space (11a1) to be air-conditioned is started according to a target temperature, if the changed temperature detected by a temperature sensor (50) is approaching the target temperature in the first space (11a1) to be air-conditioned, the controller (60) determines that the association between the controlled damper (40) and the temperature sensor (50) that detected the changed temperature is correct, but if the temperature detected by the temperature sensor (50) is not approaching to the target temperature in the first space (11a1) to be air-conditioned, the controller (60) determines that the association between the controlled damper (40) and the temperature sensor (50) that detected the changed temperature is incorrect. Then the controller (60) outputs the determination results.

Each of the plurality of dampers 40 can adjust the inflow amount of temperature-controlled air supplied to each of the plurality of target spaces 11 a based on the control of the controller 60 . For example, each of the plurality of dampers 40 is opened under the control of the controller 60 to supply temperature-controlled air to the target space 11a, or closed under the control of the controller 60 to close the target space. The supply of temperature-controlled air to 11a is stopped.

The air supplied via each of the plurality of dampers 40 circulates in each of the plurality of target spaces 11a and is supplied to the air conditioner 20 via the exhaust duct provided in each of the plurality of target spaces 11a. be.

Specifically, one or more temperature sensors 50 are provided in each of the plurality of target spaces 11a. That is, one or more temperature sensors 50 are provided in each of the plurality of target spaces 11a. Each of the plurality of temperature sensors 50 detects the room temperature of the target space 11 a and transmits temperature information indicating the detected temperature to the controller 60 .

The controller 60 can individually control a plurality of dampers 40, fans 30, air conditioners 20, and the like. Note that the controller 60 may be able to control new equipment added to the network of the central air-conditioning system 10 .

In addition, the controller 60 has a processor such as a CPU and a memory that stores programs and the like for executing predetermined processing. In addition, the controller 60 can communicate with the plurality of dampers 40, the fans 30, the air conditioners 20, etc. by wireless communication or wired communication.

The controller 60 includes an input section 61 , a display section 62 , a storage section 63 , a communication section 64 and a control section 65 .

The input unit 61 is a user interface that accepts the operations of the construction worker. The input unit 61 is realized by, for example, a touch panel, but may include hardware buttons other than the touch panel.

The display unit 62 is a monitor mounted on the controller 60, and displays the room temperature of each of the plurality of target spaces 11a, the opening degrees of the plurality of dampers 40, the operating state of the air conditioner 20, the operating state of the fan 30, and the like. In addition, the display unit 62 can also display the result determined by the control unit 65, which will be described later. The display unit 62 is, for example, a display panel such as a liquid crystal panel or an organic EL (Electro Luminescence) panel. The display unit 62 may constitute a GUI (Graphical User Interface) together with the input unit 61 .

The storage unit 63 is a storage device in which control programs and the like executed by the control unit 65 are stored. The storage unit 63 also stores setting information that associates one or more dampers 40 and one or more temperature sensors 50 provided in each of the plurality of target spaces 11a, which will be described later. The storage unit 63 is realized by, for example, a semiconductor memory or the like.

The communication unit 64 is a communication module (communication circuit) for communicating with each of the temperature sensor 50, the plurality of dampers 40, the fan 30, and the air conditioner 20 via the network. Communication performed by the communication unit 64 is, for example, wireless communication or wired communication. The communication standard used for communication is also not particularly limited.

The control unit 65 can control the plurality of dampers 40, the fans 30, the air conditioners 20, etc. by transmitting control commands to the plurality of dampers 40, the fans 30, the air conditioners 20, etc. via the communication unit 64. can. Specifically, after registering the plurality of temperature sensors 50, the plurality of dampers 40, the fans 30, the air conditioners 20, and the like in the network of the central air conditioning system 10, the control unit 65 transmits the plurality of temperature sensors 50 via the communication unit 64. Temperature information can be obtained from each of the sensors 50 . After the registration, the control unit 65 transmits control commands to the plurality of dampers 40, the fans 30, the air conditioners 20, etc. via the communication unit 64, thereby etc. can be controlled individually. The control unit 65 is implemented by, for example, a microcomputer, but may be implemented by a processor.

Also, the control unit 65 controls the opening degree of each damper 40 . Taking the first target space 11a1, which is one of the plurality of target spaces 11a, as an example, the control unit 65 adjusts the opening degrees of the one or more dampers 40 provided in the first target space 11a1. By controlling, it is possible to adjust the inflow amount of the air temperature-controlled by the air conditioner 20 into the first target space 11a1. Thereby, the room temperature of the first target space 11a1 can be adjusted. In the present embodiment, simply referring to the target space 11a is used as a generic term including the first target space 11a1 and the like.

The control unit 65 can also control the output of the air conditioner 20, the output of the fan 30 (the number of revolutions of the fan motor), and the like. For example, the control unit 65 adjusts the temperature of the air discharged from the air conditioner 20 by controlling the output of the air conditioner 20 based on the respective temperatures of the plurality of target spaces 11a detected by the respective temperature sensors 50. can also Further, the control unit 65 controls the number of revolutions of the fan 30 based on the temperature of each of the plurality of target spaces 11a detected by each temperature sensor 50, thereby controlling the amount of air conveyed whose temperature is adjusted by the air conditioner 20. It can also be adjusted.

From these, for example, when it is desired to raise the room temperature of the first target space 11a1, the control unit 65 increases the opening degree of the damper 40, increases the rotation speed of the fan 30, increase the output. As a result, the room temperature of the first target space 11a1 can be raised by supplying warm air to the first target space 11a1. Further, for example, when the room temperature of the first target space 11a1 is to be lowered, the control unit 65 increases the opening degree of the damper 40, increases the rotation speed of the fan 30, and increases the output of cold air from the air conditioner 20. . Accordingly, cold air is supplied to the first target space 11a1, so that the room temperature of the first target space 11a1 can be lowered.

In such a central air-conditioning system 10, a construction worker installs the heat exchanger 15, the air conditioner 20, the fan 30, the plurality of dampers 40, the plurality of temperature sensors 50, and the control unit 65 in the facility 1, and then installs the plurality of One or more dampers 40 and one or more temperature sensors 50 provided in each of the target spaces 11a are tied together, and after the work is performed, it is checked whether or not they are correctly tied. Therefore, the control unit 65 can execute the following processing by receiving an operation from the construction worker during the confirmation work of the tying.

The control unit 65 can set the target temperature of the first target space 11a1, which is one of the target spaces 11a. Therefore, the control unit 65 controls at least one or more dampers 40 so as to achieve the set target temperature. In other words, the controller 65 controls one or more dampers 40 corresponding to the first target space 11a1 according to the target temperature. In the present embodiment, the control unit 65 simultaneously controls the plurality of dampers 40, the fans 30, and the air conditioners 20 provided in the first target space 11a1.

In addition, the control unit 65 determines whether or not the link between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is correct for each target space 11a. After a predetermined period of time has passed since the control of the damper 40 corresponding to the first target space 11a1 was started in accordance with the target temperature, the control unit 65 (1) determines that the changed temperature detected by the temperature sensor 50 has reached the first target space. If the target temperature is approaching at 11a1, it is determined that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is correct, and (2) the temperature detected by the temperature sensor 50 is within the first target space. If the target temperature is not approached at 11a1, it is determined that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is incorrect.

That is, after a predetermined period of time has elapsed since the control of the damper 40 corresponding to the first target space 11a1 was started in accordance with the target temperature, the control unit 65 determines that the changed temperature detected by the temperature sensor 50 is the first target space 11a1. determines whether or not the target temperature is approached.

Specifically, as described in (1) above, the control unit 65 sets the temperature at the current point in the predetermined period to be higher than the temperature at the start point of the predetermined period, as detected by the temperature sensor 50. If the temperature is close to the temperature, it is determined that the temperature is close to the target temperature in the first target space 11a1. That is, the changed temperature detected by the temperature sensor 50 is the first difference value between the temperature at the start point of the predetermined period and the target temperature, and the difference value between the temperature at the end point of the predetermined period and the target temperature. If the first difference value is greater than the second difference value and the difference between the first difference value and the second difference value is equal to or greater than a predetermined value, the controller 60 sets the target temperature It is determined that it is approaching Then, the control unit 65 determines that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is correct. Here, the difference value is an absolute value. Also, the first difference value, the second difference value and the difference are also absolute values.

Further, as in (2) above, if the first difference value is greater than the second difference value and the difference between the first difference value and the second difference value is less than the predetermined value, It is determined that the target temperature is not approached in the first target space 11a1. Then, the control unit 65 determines that the connection between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is incorrect.

The control unit 65 outputs the determined result to the storage unit 63, the display unit 62, and the like. As a result, it is displayed on the display unit 62 that the damper 40 that is controlled and the temperature sensor 50 that has detected the changed temperature are incorrectly linked, and the information is also stored in the storage unit 63 .

Here, the predetermined period is an arbitrary period set in advance. Further, the difference between the start point and the end point of the predetermined period is, for example, the average value from the start point to the end point, the slope of the straight line connecting the start point and the end point, or the simple difference between the start point and the end point.

<Action>
Next, operations of the central air-conditioning system 10 and the confirmation method will be described with reference to FIG.

FIG. 3 is a flowchart showing the operation of the central air-conditioning system 10 according to the embodiment.

First, as shown in FIG. 3, the construction worker constructs the heat exchanger 15, the air conditioner 20, the fan 30, the plurality of dampers 40, the plurality of temperature sensors 50, and the control unit 65 in the facility 1. An operation of linking one or more dampers 40 and one or more temperature sensors 50 provided in each of the target spaces 11a is executed. For example, the construction worker operates using a dedicated terminal device or a terminal device in which an application for executing the tying work is installed to operate one or more terminals provided in each of the plurality of target spaces 11a. Then, the damper 40 and the one or more temperature sensors 50 are associated with each other. The control unit 65 generates setting information that links one or more dampers 40 and one or more temperature sensors 50 in each of the plurality of target spaces 11 a , and stores the generated setting information in the storage unit 63 . The terminal device here may be the controller 60 or a terminal device different from the controller 60 .

In the present embodiment, the construction worker operates the input unit 61 using the controller 60, thereby connecting the one or more dampers 40 and the one or more temperature sensors 50 provided in each of the plurality of target spaces 11a. Launch an application to perform the task of confirming the linking. After activating the application, the construction worker uses the controller 60 to confirm the linkage. This confirmation work is performed for each target space 11a. In this embodiment, confirmation work is started in order from the first target space 11a1 to the n-th target space 11an. In this flowchart, for convenience of explanation, "one or more dampers 40" and "one or more temperature sensors 50" are simply referred to as "damper 40" and "temperature sensor 50". n is a natural number of 1 or more.

Specifically, when the construction worker inputs the target temperature to the input unit 61, the control unit 65 of the controller 60 sets the target temperature of the first target space 11a1 (S11), and the set target temperature At least the damper 40 is controlled so that (S12). The control unit 65 controls the damper 40 linked to the first target space 11a1 based on the setting information stored in the storage unit 63 so that the room temperature of the first target space 11a1 reaches the target temperature. Then, these dampers 40 are opened. At this time, the controller 65 also controls the fan 30 and the air conditioner 20 at the same time. Moreover, these dampers 40 are closed by controlling the dampers 40 that are tied to areas other than the first target space 11a1.

Next, each of the plurality of temperature sensors 50 detects the temperature of the provided target space 11a, that is, the room temperature within the target space 11a (S13). Each of the plurality of temperature sensors 50 transmits temperature information indicating the detected temperature to the controller 60 at predetermined time intervals.

The control unit 65 of the controller 60 acquires the temperature information of each of the multiple target spaces 11a via the communication unit 64. In the first target space 11a1, which is one target space among the plurality of target spaces 11a, the control unit 65 determines whether or not the linkage between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is correct. judge. Specifically, based on the setting information, the control unit 65 controls the temperature sensor 50 (sometimes referred to as the first temperature sensor 50) linked to the first target space 11a1, the damper 40 (first damper ) are extracted. The control unit 65 controls the degree of opening of the first damper so as to reach the target temperature using the temperature indicated by the extracted temperature information acquired from the first temperature sensor. In the present embodiment, simply referring to the damper 40 is used as a general term including the first damper and the like. Also. In the present embodiment, simply referring to the temperature sensor 50 is used as a general term including the first temperature sensor and the like.

The control unit 65 determines whether or not a predetermined period of time has passed since the control of the opening degree of the first damper was started (S14).

When the control unit 65 determines that the predetermined period has not elapsed since the control of the opening degree of the first damper was started (NO in S14), the process returns to step S14.

When the control unit 65 determines that the predetermined period has passed since the control of the opening degree of the first damper was started (YES in S14), the changed temperature indicated by the temperature information acquired from the first temperature sensor is It is determined whether or not the first target space 11a1 is approaching the target temperature (S15).

The changed temperature detected by the first temperature sensor is a first difference value that is the difference value between the temperature at the start point of the predetermined period and the target temperature, and a second difference value that is the difference value between the temperature at the end point of the predetermined period and the target temperature. If the first difference value is greater than the second difference value and the difference between the first difference value and the second difference value is equal to or greater than a predetermined value, the first target It is determined that the room temperature of the space 11a1 is approaching the target temperature (YES in S15). Then, the control unit 65 determines that the first damper controlled in step S12 and the first temperature sensor that detected the temperature change in step S13 are correctly linked (S16).

The control unit 65 outputs the result determined in step S16 to the storage unit 63, the display unit 62, and the like. That is, the control unit 65 outputs to the storage unit 63, the display unit 62, etc., a result indicating that the first damper and the first temperature sensor provided in the first target space 11a1 are correctly linked. The storage unit 63 stores the result that the first damper and the first temperature sensor provided in the first target space 11a1 are correctly linked. In addition, the display unit 62 displays the result that the first damper and the first temperature sensor provided in the first target space 11a1 are correctly linked (S17). Then, the central air-conditioning system 10 ends the process.

Further, if the first difference value is greater than the second difference value and the difference between the first difference value and the second difference value is less than a predetermined value, the controller 60 sets the room temperature of the first target space 11a1 to the target. It is determined that the temperature has not approached (NO in S15). Then, the controller 65 erroneously associates the first damper controlled in step S12 and the first temperature sensor that detected the changed temperature in step S13 provided in the first target space 11a1 (that is, The first damper and the first temperature sensor are not linked) (S18).

The control unit 65 outputs the result determined in step S18 to the storage unit 63, the display unit 62, and the like. That is, the control unit 65 outputs to the storage unit 63, the display unit 62, etc., a result indicating that the first damper and the first temperature sensor provided in the first target space 11a1 are incorrectly linked. . The storage unit 63 stores the result that the first damper and the first temperature sensor provided in the first target space 11a1 are incorrectly linked. Further, the display unit 62 displays the result that the first damper and the first temperature sensor provided in the first target space 11a1 are incorrectly connected (S17). Then, the central air-conditioning system 10 ends the process.

In addition, since there are a plurality of target spaces 11a, by executing the above-described operation for each target space 11a, it is possible to check whether the linkage between the dampers 40 and the temperature sensors 50 provided in all the target spaces 11a is correct. It is possible to determine whether or not

Thus, the construction worker can recognize whether or not the linkage between the damper 40 and the temperature sensor 50 in each target space 11a is correct by viewing the determined result displayed on the display unit 62. will be able to

In addition, the controller 60 sets a target temperature of the first target space 11a1, which is one of the plurality of target spaces 11a, and controls the damper 40 corresponding to the first target space 11a1 according to the target temperature. , after a predetermined period of time has passed since the control of the damper 40 corresponding to the first target space 11a1 was started in accordance with the target temperature, (1) the changed temperature detected by the temperature sensor 50 reaches the target temperature in the first target space 11a1. (2) the temperature detected by the temperature sensor 50 is the target temperature in the first target space 11a1. is not approaching, it is determined that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is incorrect. The controller 60 then outputs the determined result.

According to this, the controller 60 can automatically determine whether or not the one or more dampers 40 and the one or more temperature sensors 50 in each of the plurality of target spaces 11a are correctly linked. can. For this reason, the construction worker is less likely to be forced to take a long time to check whether or not the one or more dampers 40 and the one or more temperature sensors 50 are correctly tied.

Therefore, in the central air-conditioning system 10, it is possible to suppress the lengthening of the time required for confirmation work by the construction worker.

In particular, in this central air-conditioning system 10, if the association is incorrect, the construction worker can confirm it by viewing the determination result output by the controller 60. Therefore, the construction worker can easily perform the work of confirming how the association is erroneous. Further, it is possible to prevent the work of confirming the connection between the one or more dampers 40 and the one or more temperature sensors 50 from taking a long time. Therefore, in the present embodiment, it is possible to facilitate the work of checking the connection between at least one or more dampers 40 and one or more temperature sensors 50 .

Further, the confirmation method according to the present embodiment is a confirmation method for confirming the connection between the temperature sensor 50 and the damper 40 in the central air-conditioning system 10 including the temperature sensor 50, the damper 40, and the controller 60 by using the controller 60. A target temperature is set for a first target space 11a1, which is one of a plurality of target spaces 11a provided with sensors 50 and dampers 40, and the damper 40 corresponding to the first target space 11a1 is controlled according to the target temperature. , after a predetermined period of time has passed since the control of the damper 40 corresponding to the first target space 11a1 was started in accordance with the target temperature, (1) the changed temperature detected by the temperature sensor 50 reaches the target temperature in the first target space 11a1. (2) the temperature detected by the temperature sensor 50 is the target temperature in the first target space 11a1. , it is determined that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is incorrect, and the determination result is output.

This confirmation method also has the same effect as the above.

Further, in the central air-conditioning system 10 according to the present embodiment, the changed temperature detected by the temperature sensor 50 is the first difference value, which is the difference value between the temperature at the start point of the predetermined period and the target temperature, and the end point of the predetermined period. and the second difference value, which is the difference value between the temperature and the target temperature, the controller 60 determines that the first difference value is greater than the second difference value and that the first difference value and the second difference value are equal to is equal to or greater than a predetermined value, it is determined that the temperature is approaching the target temperature.

According to this, it is possible to determine whether or not the target temperature is approaching. Therefore, whether or not the linking is correct can be accurately determined based on the difference.

In addition, in the central air-conditioning system 10 according to the present embodiment, the controller 60 determines whether or not the link between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is correct for each target space 11a. .

According to this, it is possible to determine the connection between the dampers 40 and the temperature sensors 50 in all the target spaces 11a. It is possible to suppress the need for a long time for the work of confirming the attachment.

The central air-conditioning system 10 according to the present embodiment also includes a display unit 62 that displays the results determined by the controller 60 .

According to this, by displaying the result of the determination, the construction worker recognizes, for example, that the stringing is wrong, that the stringing is correct, that the damper 40 has insufficient capacity, and the like. can do. Therefore, since the construction worker can easily recognize whether or not the stringing is correct, the confirmation work can be easily completed.

(Modification 1 of Embodiment)
Since the basic configuration of the central air-conditioning system 10 in this modification is the same as the basic configuration of the central air-conditioning system 10 of the embodiment shown in FIG. The same reference numerals are attached to the basic configuration, and the description thereof is omitted. This modification differs from the embodiment in that the second target space 11a2 that is approaching the target temperature is extracted. In this modified example, simply referring to the target space 11a is used as a generic term including the first target space 11a1 and the second target space 11a2 to the n-th target space 11an.

In the confirmation work, if the control unit 65 determines that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is incorrect, the first target space 11a1 of the plurality of target spaces 11a and the is a different space, when the changed temperature of the second target space 11a2 approaches the target temperature of the first target space 11a1, the controlled damper 40 and the changed temperature in the first target space 11a1 and the second target space 11a2 It is determined that the temperature sensor 50 that has detected is linked.

That is, when the control unit 65 determines that the connection between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is incorrect, the temperature sensor 50 provided in each of the plurality of target spaces 11a Based on the detected changed temperature, it is determined whether or not there is a change in the room temperature of the target spaces 11a other than the first target space 11a1 among the plurality of target spaces 11a. If there are other target spaces 11a with changes in room temperature, the control unit 65 extracts one or more other target spaces 11a with changes in room temperature.

Based on the changed temperature detected by the temperature sensor 50, the control unit 65 selects the second target space 11a1 that is approaching the target temperature set for the first target space 11a1 among the extracted one or more other target spaces 11a. It is determined whether or not the space 11a2 exists. When the control unit 65 determines that there is a second target space 11a2 whose temperature is approaching the target temperature set for the first target space 11a1, in the first target space 11a1 and the second target space 11a2, It is determined that the connection between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is incorrect. The control unit 65 outputs the determined result to the storage unit 63, the display unit 62, and the like. As a result, the display unit 62 displays that the damper 40 and the temperature sensor 50 are incorrectly linked in the first target space 11 a 1 and the second target space 11 a 2 , and the storage unit 63 also stores the error.

Next, the operations of the central air-conditioning system 10 and the confirmation method will be described using FIG. Note that the operation of this modified example is the same as the operation of the embodiment, so the same operation is denoted by the same reference numeral and the description thereof is omitted as appropriate.

FIG. 4 is a flowchart showing another operation of the central air-conditioning system 10 according to Modification 1 of the embodiment.

After construction, the construction worker carries out the work of confirming the connection between the one or more dampers 40 and the one or more temperature sensors 50 provided in each of the plurality of target spaces 11a. In this flowchart, for convenience of explanation, "one or more dampers 40" and "one or more temperature sensors 50" are simply referred to as "damper 40" and "temperature sensor 50".

As shown in FIG. 4, the controller 65 of the controller 60 performs the processing of steps S11 to S15 so that the first difference value is greater than the second difference value and the first difference value and the second difference value are equal to each other. If the difference from the difference value is less than the predetermined value, it is determined that the room temperature of the first target space 11a1 has not approached the target temperature (NO in S15). The control unit 65 determines that the first damper controlled in step S12 provided in the first target space 11a1 and the first temperature sensor that detected the temperature change in step S13 are incorrectly linked ( S18).

The temperature sensor 50 detects the temperature of all the target spaces 11a (S19). Each of the plurality of temperature sensors 50 transmits temperature information indicating the detected temperature to the controller 60 .

The control unit 65 of the controller 60 acquires the temperature information of all the target spaces 11a via the communication unit 64. The control unit 65 extracts a second target space 11a2, which is a target space in which the changed temperature approaches the target temperature, from among all the target spaces 11a. Based on the setting information, the control unit 65 controls the temperature sensor 50 (sometimes referred to as a second temperature sensor) and the damper 40 (sometimes referred to as a second damper) provided in the second target space 11a2. and extract

The control unit 65 determines that the controlled damper 40 in the first target space 11a1 and the second target space 11a2 is linked to the temperature sensor 50 that detects the changed temperature. That is, the control unit 65 determines that the damper 40 and the temperature sensor 50 provided in the first target space 11a1 and the damper 40 and the temperature sensor 50 provided in the second target space 11a2 are linked. (S20). Specifically, the first damper and the first temperature sensor in the first target space 11a1 and the second damper and the second temperature sensor in the second target space 11a2 are alternately linked.

The control unit 65 outputs the result determined in step S18 to the storage unit 63, the display unit 62, and the like. In other words, the control unit 65 displays the result indicating that the connection between the dampers 40 and the temperature sensors 50 provided in the first target space 11a1 and the second target space 11a2 is incorrect in the storage unit 63, the display unit 62, and the like. Output. The storage unit 63 stores the result that the dampers 40 and the temperature sensors 50 provided in the first target space 11a1 and the second target space 11a2 are incorrectly linked. In addition, the display unit 62 displays the result that the dampers 40 and the temperature sensors 50 provided in the first target space 11a1 and the second target space 11a2 are incorrectly linked (S17). Then, the central air-conditioning system 10 ends the process.

In the central air-conditioning system 10 according to this modified example, when the controller 60 determines that the connection between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is incorrect, the controller 60 determines that a plurality of target spaces When the changed temperature of the second target space 11a2, which is a space different from the first target space 11a1 in 11a, is approaching the target temperature of the first target space 11a1, the first target space 11a1 and the second target space 11a2 It is determined that the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature are linked. The controller 60 then outputs the determined result.

According to this, even if the temperature sensor 50 and the damper 40 are controlled, it is detected that the room temperature of the second target space 11a2, which is the target space 11a different from the first target space 11a1, is approaching the target temperature. In this case, it can be determined that the connection between the temperature sensor 50 provided in the first target space 11a1 and the damper 40 is incorrect. Therefore, the construction worker can recognize that the tying is incorrect by outputting the result of the determination.

This modified example differs from the embodiment in that it determines whether the damper 40 has insufficient capability.

In the confirmation work, if the control unit 65 determines that the connection between the controlled damper 40 and the temperature sensor 50 that has detected the changed temperature is correct, and the target temperature has not been reached after the elapse of the predetermined period, the damper 40 determined to be incompetent. The control unit 65 outputs the determined result to the storage unit 63, the display unit 62, and the like. As a result, the fact that the performance of the damper 40 in the first target space is insufficient is displayed on the display unit 62 and also stored in the storage unit 63 .

When the controller 65 determines that the room temperature of the first target space 11a1 has reached the target temperature after the predetermined period of time has elapsed (YES in S21), the controller 65 proceeds to step S17, stores the result of the determination in step S16 in the memory 63, Output to the display unit 62 or the like. Then, through step S17, the central air-conditioning system 10 terminates the process.

Further, when the control unit 65 determines that the room temperature of the first target space 11a1 has not reached the target temperature after the predetermined period of time has elapsed (NO in S21), the damper 40 provided in the first target space 11a1 has an ability of It is determined that there is a shortage (S22).

In the central air-conditioning system 10 according to the present modification, when the controller 60 determines that the linkage between the controlled damper 40 and the temperature sensor 50 that detects the changed temperature is correct, the target If the temperature has not been reached, it is determined that the performance of the damper 40 is insufficient. The controller 60 then outputs the determined result.

According to this, even if the damper 40 and the temperature sensor 50 are correctly linked in the first target space 11a1, if the target temperature is not reached within a predetermined period of time, it can be determined that the damper 40 has insufficient performance. can.
