Description

[Technical Field]

[0001] The present invention relates to an apparatus and method for setting a desired combined temperature of air conditioners and heaters installed in a target area, and a method for calculating basis relation information of the target area using the same, which is used to predict the amount of temperature change in the target area. [Background technology]

[0002] A heater / cooler (or air conditioner) is a device that uses a refrigeration cycle to maintain a comfortable indoor temperature suitable for human activity. A heater / cooler absorbs hot indoor air, exchanges heat with a low-temperature refrigerant, and then discharges the air back into the room to cool the room, or heat the room by doing the opposite. Generally, the operation of a heater or cooler is controlled by a direct human operation. For example, in summer, when the indoor temperature is high, the user turns on the heater or cooler and sets a desired temperature of the turned-on heater or cooler to a low value in order to quickly reduce the high indoor temperature.

[0003] Meanwhile, in spaces such as restaurants, cafes, and offices where many users are present, the manager of the space generally controls the operation of the air conditioner directly, but there is a problem that the air conditioner is not operated efficiently due to the manager's ignorance or indifference. For example, if a manager sets the desired temperature of a heater / cooler high in the summer, the user may feel hot, and if the manager sets the desired temperature of a heater / cooler low, the user may feel cold, which causes inconvenience to the user. Furthermore, if the desired temperature of a heater / cooler is set low in the summer, the power consumption of the heater / cooler increases, which increases the electricity cost of the space.

[0004] In particular, multiple air conditioners and heaters may be installed in a large space or area. In this case, if all of the multiple air conditioners and heaters are operated, unnecessary power consumption may occur due to the operation of unnecessary air conditioners and heaters.

[0005] Furthermore, when all of the multiple heaters and coolers are operated, the indoor temperature at a specific point in the zone cannot reach a comfortable temperature due to unnecessary operation of the heaters and coolers, resulting in overcooling and heating, and unnecessary power consumption. Furthermore, when only some of the multiple heaters and coolers are operated, the indoor temperature at a specific point in the zone cannot reach a comfortable temperature. Therefore, a technology is needed to efficiently operate multiple heaters and coolers without requiring an administrator to directly operate the multiple heaters and coolers. Summary of the Invention [Problem to be solved by the invention]

[0006] An object of the present invention is to provide an apparatus and method for setting a desired combined temperature of heaters and coolers installed in a target area, which prevents unnecessary operation of heaters and coolers among a plurality of heaters and coolers, prevents overcooling and overheating that occurs in some locations, and ensures that the indoor temperature at each location in the target area satisfies a comfortable temperature range, thereby minimizing power consumption. Another object of the present invention is to provide a method for calculating base relationship information of a target area, which is used to predict the amount of temperature change in the target area when one or more of a plurality of heaters and coolers are turned on. The objects of the present invention are not limited to the objects mentioned above, and other objects and advantages of the present invention not mentioned above can be understood from the following description and will become more clearly understood from the examples of the present invention. Furthermore, it is easily apparent that the objects and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims. [Means for solving the problem]

[0008] In addition, a method for calculating base relationship information used to predict a temperature change amount in a target area according to another embodiment of the present invention includes the steps of setting a desired combined temperature of one or more heaters and coolers that are operated in combination among the heaters and coolers installed in the target area, collecting a plurality of base information measured when the one or more heaters and coolers are operated at the corresponding desired combined temperatures, and calculating, based on the plurality of base information, base relationship information between the indoor / outdoor temperature difference in the target area and the temperature change amount in the target area when the one or more heaters and coolers are operated at the corresponding desired combined temperatures. In this case, the step of setting the desired combined temperature of the one or more heaters and coolers includes the steps of: setting, as the desired combined temperature of the highest priority heater and cooler, a desired temperature of the highest priority heater and cooler that embodies an indoor temperature of the target area that is most similar to a comfort temperature range of the target area, based on at least one test drive of a highest priority heater and cooler among the heaters and coolers; and, when the indoor temperatures of at least some of the temperature sensors of the target area are not within the comfort temperature range in a situation where the highest priority heater and cooler are driven at the corresponding desired combined temperature, setting, as the desired combined temperature of the at least some of the heaters and coolers, desired temperatures of at least some of the heaters and coolers other than the highest priority heater and cooler that make the indoor temperature of the target area and the indoor temperatures of the temperature sensors fall within the comfort temperature range, based on at least one test drive of the heaters and coolers other than the highest priority heater and cooler.

[Effects of the Invention]

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing a schematic configuration of a space 1 according to an embodiment of the present invention. 1, a space 1 includes a plurality of zones 10a and 10b. The zones 10a and 10b are separated from each other by interior walls. Because they are separated by the interior walls, the indoor temperatures and humidity levels of the zones 10a and 10b may differ from each other.

[0018] Each of the plurality of zones 10a, 10b may be provided with a heater / cooler 20, a temperature / humidity sensor 30, and a control module 40. A gateway 50 may be provided in at least one of the zones 10a, 10b. Although not shown in FIG. 1, an access point 60 (see FIG. 2) may be further provided in a specific zone of the plurality of zones 10a, 10b.

[0019] Hereinafter, the present invention will be described assuming that the area 10b in which the gateway 50 is installed is the target area 10. FIG. 2 is a diagram showing a schematic configuration of a cooling and heating machine control system 2 according to an embodiment of the present invention. Referring to FIG. 2, the air conditioner control system 2 includes a temperature and humidity sensor 30, a control module 40, a gateway 50, an access point 60, and a management server 70.

[0020] The temperature and humidity sensor 30 can measure the indoor temperature and humidity of the target area 10. To this end, the temperature and humidity sensor 30 can include a temperature sensor module and a humidity sensor module. The temperature and humidity sensor 30 may be installed in a position where it can measure the temperature and humidity in the area where people mainly perform activities, but is not limited thereto, and the temperature and humidity sensor 30 may also be built into the air conditioner 20.

[0021] The temperature and humidity sensor 30 can communicate with other electronic devices within the target area 10. To this end, the temperature and humidity sensor 30 can include a short-range communication module. As an example, the temperature and humidity sensor 30 can include a Bluetooth (registered trademark) communication module, but the present invention is not limited thereto.

[0022] The control module 40 may be a device that transmits a drive control signal to the air conditioner 20 to control the operation of the air conditioner 20. The control module 40 may be installed in a specific portion of the target area 10 adjacent to the air conditioner 20. As will be described later, the drive control signal may be generated by the management server 70 and transmitted from the management server 70 to the control module 40 via the access point 60 and the gateway 50.

[0023] For this purpose, the control module 40 may include a short-range communication module and an infrared data association (IrDA) module. As an example, the control module 40 may include a Bluetooth communication module, although the present invention is not limited thereto.

[0024] The gateway 50 can communicate with each of the temperature and humidity sensor 30, the control module 40, and the access point 60. To this end, the gateway 50 may include a first short-range communication module for communicating with the temperature and humidity sensor 30 and the control module 40, and a second short-range communication module for communicating with the access point 60. As an example, the first short-range communication module may be a Bluetooth communication module, and the second short-range communication module may be a Wi-Fi (Wireless fidelity) communication module, but the present invention is not limited thereto.

[0025] The gateway 50 can receive indoor temperature and humidity information from the temperature and humidity sensor 30 and then transfer the information to the access point 60. The gateway 50 can also receive a drive control signal for the air conditioner 20 (described later) from the access point 60 and then transfer the signal to the control module 40. The gateway 50 can also receive drive-related data for the air conditioner 20 from the control module 40.

[0026] The access point 60 can relay communications between the gateway 50 and the management server 70. To this end, the access point 60 can include a second short-range communication module and a long-range communication module.

[0027] The management server 70 may be a device that actually controls the air conditioner 20. The management server 70 may be communicatively connected to the access point 60 and the weather server 80. The management server 70 may receive indoor temperature and humidity information of the target area 10 from the access point 60, and may receive weather information of the target area 10 from the weather server 80. The management server 70 may generate a drive control signal for the air conditioner 20 using the indoor temperature and humidity information and the weather information of the target area 10, and may transmit the drive control signal to the access point 60.

[0028] The weather server 80 may be a server that provides weather information (meteorological information) for each administrative region. The weather information may be forecast information. The weather information may include outdoor temperature, cloud cover, probability of precipitation, humidity, etc.

[0029] Meanwhile, in order to make the indoor temperature at each point in the target area 10 fall within the comfortable temperature range, one or more of the heaters and coolers 20 may be operated in combination. Hereinafter, a more detailed description will be given of the management server 70 that calculates a desired combined temperature of one or more heaters and coolers 20 when one or more heaters and coolers 20 are operated in combination, and calculates base relation information based on base information measured when one or more heaters and coolers 20 are operated at the set desired combined temperature.

[0030] FIG. 3 is a diagram showing a schematic configuration of a management server 70 according to an embodiment of the present invention, and FIG. 4 is a diagram showing a simplified view of a target area 10 in the space 1 of FIG.

[0031] Here, three air conditioners 20 (20a, 20b, 20c) and four temperature and humidity sensors 30 (30a, 30b, 30c, 30d) are installed in the target area 10. Meanwhile, the number of air conditioners 20 and temperature and humidity sensors 30 installed in the target area 10 is not limited to that shown in FIG. 4, and for ease of explanation, the "temperature and humidity sensors 30" will be referred to as "temperature sensors 30."

[0032] Referring to FIG. 3, the management server 70 may include a communication unit 710, a control unit 720, and a storage unit 730. The function of each component will be described in detail below.

[0033] The communication unit 710 may be a module that communicates with the access point 60. As an example, the communication unit 710 may include a long-distance communication module implemented in wired or wireless communication, but the present invention is not limited thereto. As described above, the communication unit 710 can receive indoor temperature information and indoor humidity information measured by the plurality of temperature sensors 20 via the access point 60.

[0034] The control unit 720 may include a memory and a processor. The memory may be volatile and / or non-volatile memory and may store instructions or data related to at least one other component of the management server 70. The processor may include one or more of a central processing unit (CPU), an application processor, or a communication processor.

[0035] The control unit 720 can control the communication unit 710 and generate drive control signals for the plurality of coolers and heaters 20. Here, the drive control signal may be a first drive control signal that controls the drive (i.e., test drive) of one or more of the plurality of coolers and heaters 20 on a test day, or a second drive control signal that controls the drive of one or more of the plurality of coolers and heaters 20 on a target day.

[0036] In addition, the control unit 720 may set a desired combined temperature for one or more of the plurality of heaters and coolers 20 based on test driving of one or more of the heaters and coolers 20. Here, the desired combined temperature for each of the one or more heaters and coolers 20 may be the desired temperature for each of the one or more heaters and coolers 20 when the one or more heaters and coolers 20 are driven in combination at the same time. As an example, if two of three heaters and coolers 20, 20a and 20b, are driven and one heater and cooler 20c is not driven, a desired combined temperature may be set for the two heaters and coolers 20a and 20b, but a desired combined temperature may not be set for the one heater and cooler 20c. By using the desired combined temperature for one or more heaters and coolers 20, the indoor temperature at each point in the target area 10 may reach a comfortable temperature range, thereby preventing unnecessary operation of the heaters and coolers 20. As an example, each point in the target area 10 may be a location where a plurality of temperature sensors 30 are installed in the target area 10.

[0037] In addition, the control unit 720 can calculate base relationship information based on the desired combined temperature of one or more air conditioners 20, and can predict the amount of temperature change in the target area 10 when one or more air conditioners 20 are turned on at the desired combined temperature based on the base relationship information. Here, the base relationship information can be defined as relationship information between the indoor / outdoor temperature difference in the target area 10 and the amount of temperature change in the target area 10 when one or more air conditioners 20 are operated at the desired combined temperature.

[0038] The storage unit 730 may store various information related to the operation control of the cooler / heater 20 . In the following, the concepts of the comfort temperature region and the thermal influence of the air conditioner 20 will be defined first, and then the operations performed by the management server 70 will be described in detail with reference to FIG. 5 and the like.

[0039] 1. Comfortable temperature range The comfort temperature region can be defined as the temperature region in which a user positioned in the target area 10 feels comfortable. The comfort temperature range can be set in the form of a temperature range. For example, the comfort temperature range can be set as "23.5°C to 24.5°C." The comfort temperature zone may be set differently for each season. For example, the comfort temperature zone in summer may be higher than the comfort temperature zone in winter.

[0040] The comfort temperature zone may be set differently for each period included in a specific day. Here, the multiple periods may refer to sequential time intervals included in a target day. The multiple periods may be set based on an operation schedule for the target area 10. The unit time, defined as the length of a period, can be set in various ways. For example, the unit time can be set to one hour. Therefore, the comfort temperature range for the period "7:00 to 7:59" and the comfort temperature range for the period "8:00 to 8:59" can be set separately.

[0041] Meanwhile, an uncomfortable temperature region, which is a temperature region other than the comfortable temperature region, can be defined. In this case, first and second uncomfortable temperature regions can be defined based on the comfortable temperature region. Here, the first uncomfortable temperature region can be defined as a temperature region where the heating and cooling load is higher than that of the comfortable temperature region, and the second uncomfortable temperature region can be defined as a temperature region where the heating and cooling load is lower than that of the comfortable temperature region.

[0042] That is, the first non-comfortable temperature region can have a temperature higher than the comfortable temperature region in the cooling mode of the air conditioner 20 and can have a temperature lower than the comfortable temperature region in the heating mode of the air conditioner 20. The second non-comfortable temperature region can have a temperature lower than the comfortable temperature region in the cooling mode of the air conditioner 20 and can have a temperature higher than the comfortable temperature region in the heating mode of the air conditioner 20.

[0043] As one example, when the air conditioner 20 is operated in a cooling mode and the comfortable temperature range in summer is set to "23.5°C to 24.5°C," the first uncomfortable temperature range may be a temperature range of 24.6°C or higher, and the second uncomfortable temperature range may be a temperature range of 23.4°C or lower. As another example, when the air conditioner 20 is operated in a heating mode and the comfortable temperature range in winter is set to "25.5°C to 26.5°C," the first uncomfortable temperature range may be a temperature range of 25.4°C or lower, and the second uncomfortable temperature range may be a temperature range of 26.6°C or higher.

[0044] 2. Thermal impact of the air conditioner 20 The thermal impact of the air conditioners 20 can be defined as the impact on the indoor temperature of the target area 10. In other words, the air conditioners 20 installed in the target area 10 may differ from one another in terms of installation location, cooling capacity, power consumption, energy consumption efficiency, etc., and therefore the thermal impact of the air conditioners 20 may differ from one another. The thermal impact of each of the heaters and coolers 20 can be preset by the management server 70 before performing the step of Fig. 5 described below. In particular, the management server 70 can set the heater / cooler 20 that has the greatest thermal impact on the indoor temperature of the target area 10 as the highest priority heater / cooler 20. The thermal influence degree of the air conditioner 20 can be set based on at least one of the first thermal influence degree and the second thermal influence degree.

[0045] The first thermal influence degree of the air conditioner 20 may correspond to the degree to which the indoor temperature at each point in the target area 10 is changed in the same manner. In other words, the first thermal influence degree of the air conditioner 20 may correspond to the degree to which the indoor temperature change amount at each point in the target area 10 is distributed when the air conditioner 20 is operating. Here, each point may include a location where a plurality of temperature and humidity sensors 30 are installed.

[0046] The first thermal influence of the air conditioner 20 and the degree of variance of the amount of indoor temperature change at each point in the target area 10 may have an inversely proportional relationship. That is, the greater the first thermal influence of the air conditioner 20, the smaller the degree of variance of the amount of indoor temperature change at each point in the target area 10, and the smaller the first thermal influence of the air conditioner 20, the greater the degree of variance of the amount of indoor temperature change at each point in the target area 10. The second thermal influence degree of the air conditioner 20 can correspond to the degree of change in the overall indoor temperature of the target area 10. In other words, the second thermal influence degree of the air conditioner 20 can correspond to the amount of change in the overall indoor temperature of the target area 10 when the air conditioner 20 is operating.

[0047] The greater the second thermal influence of the air conditioner 20, the greater the change in the overall indoor temperature of the target area 10, and the faster the overall indoor temperature of the target area 10 may change. Also, the smaller the second thermal influence of the air conditioner 20, the smaller the change in the overall indoor temperature of the target area 10, and the slower the overall indoor temperature of the target area 10 may change.

[0048] For example, the thermal influence of the air conditioner 20 may correspond to a sum of a value obtained by adding a first weighted value to a first thermal influence and a value obtained by adding a second weighted value to a second thermal influence. The first and second weighted values ​​may be set differently depending on the operating mode of the air conditioner (for example, an energy saving mode, an energy uniform mode, etc.). Hereinafter, "thermal influence" will be referred to as "influence."

[0049] 3. Setting the desired temperature combination and calculating the base relation information FIG. 5 is a diagram showing an overall flowchart of a method for calculating basis relation information of a target area 10 according to an embodiment of the present invention. As described above, the method for calculating the base relation information for the target area 10 can be performed by the management server 70. Hereinafter, the process performed in each step will be described in detail. In this case, the present embodiment will be described assuming that the temperature sensor is the temperature sensor 30.

[0050] In step (S10), the management server 70 can set a combined desired temperature, which is the desired temperature of each of one or more heaters and coolers 20 that are operated in combination among the heaters and coolers 20 installed in the target area 10, so that all indoor temperatures of the temperature sensors 30 in the target area 10 are included in the comfortable temperature range. Here, the indoor temperature of the target area 10 corresponds to the indoor temperature of the entire target area 10, and the indoor temperature of the temperature sensor 30 can correspond to the indoor temperature of each point where the temperature sensor 30 is installed.

[0051] Step S10 can be performed at a specific time interval on the test day.

[0052] Hereinafter, the detailed process of step S10 will be described in detail with reference to FIG. FIG. 6 is a flowchart showing step (S10) of FIG. In step (S11), the management server 70 may set the desired temperature of the highest priority heater / cooler 20 that embodies the indoor temperature of the target area 10 that is most similar to the comfort temperature area as the combined desired temperature of the highest priority heater / cooler 20.

[0053] Here, the indoor temperature of the target area 10 that is most similar to the comfort temperature area may be the indoor temperature of the target area 10 that is included in the comfort temperature area, or it may be the indoor temperature of the target area 10 that is included in the first non-comfortable temperature area and is closest to the comfort temperature area.

[0054] Figure 7 is a flowchart of step S11 of Figure 6. The process performed in each step will now be described.

[0055] In step S1101, the management server 70 may control the highest priority heater / cooler 20 to be test-driven at the default desired test temperature. Thus, the highest priority heater / cooler 20 may be test-driven. For example, the test drive time may be 40 minutes or more, and the preset default desired test temperature may be 24° C. during the first test drive.

[0056] In step S1102, the management server 70 may determine whether the indoor temperature of the target area 10 in the current test is within a first uncomfortable temperature region. If the indoor temperature of the target area 10 is within the first uncomfortable temperature region, steps S1105 to S1108 may be performed. If the indoor temperature of the target area 10 is not within the first uncomfortable temperature region, step S1103 may be performed.

[0057] Meanwhile, the indoor temperature of the target area 10 may correspond to the average value of the indoor temperatures measured by each of the temperature sensors 30 installed in the target area 10. Alternatively, the indoor temperature of the target area 10 may be a converged value of the indoor temperatures directly measured by the temperature sensors 30. That is, when the air conditioner 20 is continuously operated at a specific desired temperature, the indoor temperature of the target area 10 has a characteristic of decreasing by a certain value and then being maintained. Therefore, the converged indoor temperature may correspond to the maintained indoor temperature of the target area 10, which may be inferred based on the rate of change of the indoor temperature of the target area 10 during test operation. However, the present invention is not limited thereto, and the indoor temperature of the target area 10 may also be the average value of the indoor temperatures directly measured by the temperature sensors 30.

[0058] If the indoor temperature of the target area 10 is within the first uncomfortable temperature region, in step (S1105), the management server 70 can determine whether the indoor temperature of the target area 10 in the previous test is within the second uncomfortable temperature region. If the indoor temperature of the target area 10 in the previous test is not within the second non-comfortable temperature range, the management server 70 may change the desired test temperature of the highest priority air conditioner 20 by a unit temperature (e.g., 0.5°C or 1°C) in step S1106 so that the power consumption of the highest priority air conditioner 20 increases, and may test drive the highest priority air conditioner 20 at the changed desired test temperature of the highest priority air conditioner 20 in step S1107. After this, step S1102 may be performed again. Meanwhile, if the current test is the first test, there is no previous test, so step S1106 may be performed.

[0059] Specifically, when the air conditioners 20 are operating in cooling mode, the direction in which the power consumption of the highest priority air conditioner 20 increases can correspond to decreasing the desired test temperature of the air conditioner 20 by a unit temperature. Also, when the air conditioners 20 are operating in heating mode, the direction in which the power consumption of the highest priority air conditioner 20 increases can correspond to increasing the desired test temperature of the air conditioner 20 by a unit temperature. Conversely, if the indoor temperature of the target area 10 in the immediately preceding test is within the second non-comfortable temperature region, in step (S1108), the management server 70 can set the desired test temperature of the highest priority heater / cooler 20 in the current test to the desired combined temperature of the highest priority heater / cooler 20.

[0060] On the other hand, if the indoor temperature of the target area 10 is not within the first uncomfortable temperature region, the management server 70 may determine whether the indoor temperature of the target area 10 is within a second uncomfortable temperature region in step S1103. If the indoor temperature of the target area 10 is within the second uncomfortable temperature region, steps S1107, S1109, and S1110 may be performed. If the indoor temperature of the target area 10 is not within the second uncomfortable temperature region, step S1104 may be performed.

[0061] If the indoor temperature of the target zone 10 in the previous test is not within the first non-comfortable temperature range, the management server 70 may change the desired test temperature of the highest priority cooler / heater 20 by one unit temperature in a direction that reduces the power consumption of the highest priority cooler / heater 20 in step S1110, and may test drive the highest priority cooler / heater 20 at the changed desired test temperature of the highest priority cooler / heater 20 in step S1107. After this, step S1102 may be performed again. Meanwhile, if the current test is the first test, there is no previous test, so step S1109 may be performed.

[0062] Specifically, when the air conditioners 20 are operating in cooling mode, the direction in which the power consumption of the highest priority air conditioner 20 decreases can correspond to increasing the desired test temperature of the air conditioner 20 by a unit temperature. Also, when the air conditioners 20 are operating in heating mode, the direction in which the power consumption of the highest priority air conditioner 20 decreases can correspond to decreasing the desired test temperature of the air conditioner 20 by a unit temperature.

[0063] Conversely, if the indoor temperature of the target area 10 in the previous test is included in the first non-comfortable temperature region, in step (S1111), the management server 70 can set the test desired temperature of the highest priority heater / cooler 20 in the previous test to the combined desired temperature of the highest priority heater / cooler 20.

[0064] On the other hand, if the indoor temperature of the target area 10 is not included in the second non-comfortable temperature area, this corresponds to the indoor temperature of the target area 10 being included in the comfortable temperature area, so in step (S1104), the management server 70 can set the test desired temperature of the highest priority heater / cooler 20 in the current test to the combined desired temperature of the highest priority heater / cooler 20.

[0065] Meanwhile, steps S1102 and S1103 may correspond to determining whether the indoor temperature of the target area 10 is within the comfort temperature range. Steps S1106 and S1110 may correspond to changing the desired test temperature of the highest priority air conditioner 20 by a unit temperature.

[0066] Hereinafter, the example of Fig. 7 will be explained by dividing it into a cooling mode and a heating mode, where the unit temperature is assumed to be 1°C.

[0067] a) Cooling mode operation of the air conditioner 20 If the comfort temperature range for the test day is set to 24.5°C to 25.5°C, the desired test temperature of the highest priority heater / cooler 20 in the first test is set to 24°C, and the indoor temperature of the target area 10 in the first test is 24.7°C, the management server 70 can set the desired test temperature (24°C) of the highest priority heater / cooler 20 in the current test (first test) to the desired combined temperature of the highest priority heater / cooler 20 via "Step (S1102) → Step (S1103) → Step (S1104)".

[0068] Furthermore, if the comfort temperature range on the test day is set to 23.5°C to 24.5°C, the desired test temperature of the highest priority heater / cooler 20 in the first test is set to 24°C, and the indoor temperature of the target area 10 in the first test is 24.9°C, two test runs are performed, and via step (S1102) → step (S1105) → step (S1106) → step (S1107) → step (S1102) → step (S1103) → step (S1109) → step (S1111), the management server 70 can set the desired test temperature (24°C) of the highest priority heater / cooler 20 in the previous test (first test) as the desired combined temperature of the highest priority heater / cooler 20.

[0069] Furthermore, if the comfort temperature range on the test day is set to 23.5°C to 24.5°C, the desired test temperature of the highest priority heater / cooler 20 in the first test is set to 23°C, and the indoor temperature of the target area 10 in the first test is 23.1°C, two test runs are performed, and via step (S1102) → step (S1103) → step (S1109) → step (S1110) → step (S1107) → step (S1102) → step (S1105) → step (S1108), the management server 70 can set the desired test temperature (24°C) of the highest priority heater / cooler 20 in the current test (second test) to the desired combined temperature of the highest priority heater / cooler 20.

[0070] b) Heating mode operation of the air conditioner 20 If the comfort temperature range for the test day is set to 25.8°C to 26.3°C, the desired test temperature of the highest priority heater / cooler 20 in the first test is set to 26°C, and the indoor temperature of the target area 10 in the first test is 25.9°C, the management server 70 can set the desired test temperature (26°C) of the highest priority heater / cooler 20 in the current test (first test) as the desired combined temperature of the highest priority heater / cooler 20 via "Step (S1102) → Step (S1103) → Step (S1104)".

[0071] Furthermore, if the comfort temperature range on the test day is set to 26.2°C to 26.7°C, the desired test temperature of the highest priority heater / cooler 20 in the first test is set to 26°C, and the indoor temperature of the target area 10 in the first test is 25.9°C, two test runs are performed, and via step (S1102) → step (S1105) → step (S1106) → step (S1107) → step (S1102) → step (S1103) → step (S1109) → step (S1111), the management server 70 can set the desired test temperature (26°C) of the highest priority heater / cooler 20 in the previous test (first test) as the desired combined temperature of the highest priority heater / cooler 20.

[0072] Furthermore, if the comfort temperature range on the test day is set to 26.2°C to 26.7°C, the desired test temperature of the highest priority heater / cooler 20 in the first test is set to 27°C, and the indoor temperature of the target area 10 in the first test is 26.9°C, two test runs are performed, and via step (S1102) → step (S1103) → step (S1109) → step (S1110) → step (S1107) → step (S1102) → step (S1105) → step (S1108), the management server 70 can set the desired test temperature (26°C) of the highest priority heater / cooler 20 in the current test (second test) as the desired combined temperature of the highest priority heater / cooler 20.

[0073] In short, in step S11, the management server 70 can set the desired temperature of the highest priority heater / cooler 20 that embodies the indoor temperature of the target area 10 most similar to the comfort temperature region of the target area 10 as the combined desired temperature of the highest priority heater / cooler 20 based on at least one test drive of the highest priority heater / cooler 20. The combined desired temperature of the highest priority heater / cooler 20 can be used when one or more heaters / coolers 20 are driven in combination.

[0074] Referring again to FIG. 6, after the desired combined temperature of the highest priority air conditioner 20 is set, in step (S12), the management server 70 can determine whether each indoor temperature for each temperature sensor is within the comfortable temperature range. That is, the indoor temperatures measured by each temperature sensor 30 may differ depending on the installation positions of the temperature sensors 30, and as a result, the indoor temperatures of some temperature sensors 30 may be within the comfortable temperature range, while the indoor temperatures of other temperature sensors 30 may not be within the comfortable temperature range. This situation may occur regardless of whether the entire indoor temperature of the target area 10 is within the comfortable temperature range. One of the objectives of the present invention is to ensure that the indoor temperatures of all points in the target area 10 are within the comfortable temperature range, and step S12 may be performed to achieve this.

[0075] If the indoor temperatures of the respective temperature sensors are not within the comfortable temperature range, i.e., if the indoor temperatures of at least some of the temperature sensors 30 are within the first or second uncomfortable temperature range, step (S12) may be performed again after steps (S13) to (S15) are performed.

[0076] Specifically, in step S13, the management server 70 may calculate ranking information of the temperature sensors 30 based on the indoor temperature and the comfortable temperature range for each temperature sensor. According to the embodiment, the management server 70 can sort the indoor temperatures of each temperature sensor in descending order of the difference between the indoor temperature of the temperature sensor 30 and the comfortable temperature range, and calculate the ranking information of the temperature sensors 30 based on the sorted indoor temperatures of each temperature sensor.

[0077] In step (S14), the management server 70 can select the first air conditioner 20 having the temperature sensor influence ranking information most similar to the temperature sensor 30 ranking information from among the air conditioners 20 for which the desired combined temperature is not set.

[0078] Referring to FIG. 6, steps S12 to S16 are repeated, so the heater / cooler 20 for which the desired combined temperature is not set may refer to a heater / cooler 20 other than the heater / cooler 20 for which the same desired combined temperature as the top heater / cooler 20 described above is set.

[0079] According to the embodiment, the management server 70 can select the first heater / cooler 20 by comparing the similarity between the ranking information of the temperature sensor influence degree of the heater / cooler 20 for which the desired combined temperature is not set and the ranking information of the temperature sensor 30 based on a publicly known similarity comparison algorithm.

[0080] As an example, in an environment like that shown in Figure 4, if the heater / cooler a (20a) is the highest-priority heater / cooler 20 for which a desired combined temperature is set, the heater / cooler 20 for which a desired combined temperature is not set is heater / cooler b (20b) and heater / cooler c (20c). Assume that the ranking information of the temperature sensors 30 is "b, c, d, a," the ranking information of the temperature sensor influence degree of the heater / cooler b (20b) is "b, d, c, a," and the ranking information of the temperature sensor influence degree of the heater / cooler c (20c) is "c, d, b, a." Meanwhile, assume that a, b, c, and d refer to the temperature sensors a (30a), b (30b), c (30c), and d (30d), respectively, and that the indoor temperatures of the temperature sensors b (30b) and c (30c) are not included in the comfortable temperature range. In this case, the management server 70 can calculate the air conditioner b (20b) as the first air conditioner 20.

[0081] In short, step (S14) corresponds to a step of selecting the first air conditioner having the temperature sensor-specific influence degree most similar to the indoor temperature of each temperature sensor among the air conditioners 20 for which the desired combined temperature is set, when the indoor temperature of at least some of the temperature sensors 30 is not included in the comfortable temperature range in a situation where the air conditioners 20 for which the desired combined temperature is set are operated at the corresponding desired combined temperature.

[0082] In step (S15), the management server 70 can set the desired temperature of the first air conditioner 20 as the combined desired temperature of the first air conditioner 20, which can realize the indoor temperature of the target area 10 that is most similar to the comfortable temperature area when the air conditioner 20 for which the combined desired temperature is set is operated at the corresponding combined desired temperature.

[0083] FIG. 8 is a flowchart showing step (S15) of FIG. Referring to Figure 8, step S15 may be performed similarly to step S11 of Figure 7. That is, steps S1501 to S1511 of Figure 8 correspond to steps S1101 to S1111 of Figure 7, except that in steps S1501 and S1507, the coolers / heaters 20 for which the desired combined temperatures are set are both driven during the test drive. Therefore, the description of step S11 above should be referred to for step S15.

[0084] In short, step (S15) may be a step of setting a desired combined temperature of the first air conditioner 20 that can realize the indoor temperature of the target area 10 that is most similar to the comfort temperature area by test-driving the first air conditioner 20 at least once while the air conditioner 20 for which the desired combined temperature is set is driven at the corresponding desired combined temperature.

[0085] 6, after step S15 is performed, step S12 may be performed again, i.e., the management server 70 may again determine whether the indoor temperatures of the respective temperature sensors are within the comfort temperature range.

[0086] On the other hand, if the indoor temperatures of the respective temperature sensors are within the comfort temperature range, the management server 70 may complete setting of the combined desired temperature for each of the one or more heaters and coolers 20 to be operated in combination in step S16. At this time, the heaters and coolers 20 for which the combined desired temperature is not set may be set as not being operated.

[0087] That is, i) when the highest priority heater / cooler 20 is operated at the corresponding desired combined temperature and all the indoor temperatures of the temperature sensors 30 in the target area 10 are within the comfort temperature range, only the highest priority heater / cooler 20 can be set to be operated at the corresponding desired combined temperature; ii) when the highest priority heater / cooler 20 is operated at the corresponding desired combined temperature and the indoor temperatures of at least some of the temperature sensors 30 are not within the comfort temperature range, the highest priority heater / cooler 20 and at least some of the heaters / coolers 20 can be set to be operated at the corresponding desired combined temperature; and iii) heaters / coolers 20 other than the highest priority heater / cooler 20 and at least some of the heaters / coolers 20 can be set not to be operated.

[0088] The above content can be summarized as follows: The indoor temperature of the target area 10 may correspond to the average value of the individual indoor temperatures measured by the temperature sensors 30. In this case, even if the indoor temperature of the target area 10 is within the comfort temperature range, some individual indoor temperatures may not be within the comfort temperature range. Therefore, the management server 20 can adjust the indoor temperature of the target area 10 to approximate the comfort temperature range by driving the highest priority air conditioner / heater 20, and if there are some individual indoor temperatures that are not within the comfort temperature range, can drive only the air conditioner / heater 20 that has a significant impact on those individual indoor temperatures. This prevents unnecessary driving of the air conditioner / heater 20, prevents overcooling and heating at some points, and minimizes power consumption of the air conditioner / heater 20 by ensuring that the indoor temperature at each point in the target area 10 satisfies the comfort temperature range.

[0089] Referring again to FIG. 5, in step S20, the management server 70 may collect baseline information measured when one or more coolers 20 are operated at the corresponding combined desired temperatures. Step S20 may be performed during a specific time period on an additional test date after the test date.

[0090] The base information may be information on the amount of temperature change in the target area 10 due to the difference between the indoor and outdoor temperatures in the target area 10 when one or more air conditioners 20 are driven at the desired combined temperature described above. The indoor / outdoor temperature difference of the target area 10 is the subtraction value (T o -T i ) In this case, the outdoor temperature of the target area 10 can be collected from the weather server 80, and the indoor temperature of the target area 10 can be measured by the temperature sensor 30.

[0091] The temperature change amount of the target area 10 may be defined as the temperature change amount per unit time of the target area 10. As an example, the unit time may be one hour, but the present invention is not limited thereto. The baseline information may be collected at a predetermined interval. For example, if the length of the midnight period is one hour, the baseline information may be collected every 10 minutes.

[0092] In step S30, the management server 70 can calculate the base relation information of the target area 10 based on the base information. The base relationship information can be defined as relationship information between the indoor / outdoor temperature difference in the target area 10 and the temperature change amount in the target area 10 when one or more air conditioners 20 are operated.

[0093] According to an embodiment, the basis relation information may be expressed as a basis relation function equation corresponding to a trend line for a plurality of pieces of basis information. According to an embodiment, the trend line may be a polynomial trend line, particularly a quadratic polynomial trend line. That is, the basis relation information may correspond to a basis relation polynomial function equation that outputs the temperature change amount of the target area 10 using the indoor / outdoor temperature difference of the target area 10 as a variable. In this case, the basis relation information may be set separately for the cooling mode and the heating mode of the air conditioner 20.

[0094] According to the embodiment, in each of the cooling mode and the heating mode, the function value of the basis relation polynomial can be expressed as the following Equation 1.

number

[0095] Meanwhile, the base relation information can be used to predict the amount of temperature change in the target area 10 on a target day. In particular, the management server 70 can calculate the target relation information by reflecting weather information (e.g., cloud cover information) on the target day in the base relation information, and predict the amount of temperature change in the target area 10 based on the target relation information. In short, by calculating the base relation information of the target area 10 when one or more of the air conditioners 20 are driven, the temperature change amount information of the target area 10 can be accurately predicted.

[0096] Meanwhile, the above-described operations may also be performed by the control module 40 rather than the management server 70. In this case, the control module 40 may include a high-performance processor-based control unit and may further include the second short-range communication module and infrared communication module described above. The control module 40 may obtain weather information for the target area 10 from the weather server 80 via the access point 60 and the gateway 50, and may obtain the indoor temperature and humidity for the target area 10 measured by the temperature and humidity sensor 30 via the gateway 50. The temperature and humidity sensor 30 and the control module 40 may also be built into the air conditioner 20. In this case, the control module 40 may directly obtain the indoor temperature and humidity from the temperature and humidity sensor 30. The operations performed by the control module 40 are similar to those described above, and therefore a detailed description thereof will be omitted.

[0097] Furthermore, embodiments of the present invention may be embodied in the form of program instructions that can be executed by various computer means and stored on a computer-readable medium. The computer-readable medium may include, alone or in combination, program instructions, data files, data structures, and the like.
