Description

Technical Field

[0001] Embodiments of the present invention relate to a device and method for setting a combined desired temperature of a cooling and heating air conditioner installed in a target area, and a method for calculating basic relationship information of the target area for predicting a temperature change amount of the target area using the same. Background Art

[0002] A cooling and heating air conditioner (or air conditioner) is a device that maintains a comfortable indoor temperature using a refrigeration cycle to suit people's activities. The cooling and heating air conditioner cools the room by sucking in indoor hot air and discharging it into the room after heat exchange with a low-temperature refrigerant, or heats the room by the opposite action.

[0003] Generally speaking, the operation of a cooling and heating air conditioner is directly controlled by a person. For example, when the indoor temperature is high in summer, the user will turn on the cooling and heating air conditioner and set the desired temperature of the turned-on cooling and heating air conditioner low to quickly reduce the high indoor temperature.

[0004] On the other hand, in spaces such as restaurants, cafes, and offices where there are a large number of users, the operation of the cooling and heating air conditioner is generally directly controlled by the space manager. However, there is a problem that the manager does not know or does not pay attention, resulting in ineffective operation of the cooling and heating air conditioner.

[0005] For example, in summer, when the manager sets the desired temperature of the cooling and heating air conditioner high, the user may feel hot, and when the manager sets the desired temperature of the cooling and heating air conditioner low, the user may feel cold. Therefore, the user will feel inconvenient. In particular, when the desired temperature of the cooling and heating air conditioner is set low in summer, the power consumption of the cooling and heating air conditioner increases, so there is a problem of rising electricity bills for the space.

[0006] In particular, multiple cooling and heating air conditioners may be installed in a large space or area. At this time, when multiple cooling and heating air conditioners are all operating, there is a problem of unnecessary power consumption due to the operation of unnecessary cooling and heating air conditioners.

[0007] In addition, when multiple cooling and heating air conditioners are all operating, due to the operation of unnecessary cooling and heating air conditioners, the indoor temperature at a specific location in the area cannot reach a comfortable temperature, resulting in excessive cooling or heating and unnecessary power consumption. In addition, when only some of the multiple cooling and heating air conditioners are operating, there is also a problem that the indoor temperature at some locations in the area cannot reach a comfortable temperature. Therefore, a technology for effectively operating multiple cooling and heating air conditioners without the manager directly operating them is needed. Summary of the Invention

[0030] Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

[0031] Figure 1 is a diagram showing a brief configuration of a space 1 according to an embodiment of the present invention.

[0032] See Figure 1 , the space 1 includes a plurality of regions 10a, 10b. The plurality of regions 10a, 10b can be separated from each other by interior walls. Since they are separated by interior walls, the indoor temperature and humidity of each of the plurality of regions 10a, 10b may be different.

[0033] Each of the plurality of regions 10a, 10b can be respectively equipped with a heating and cooling air conditioner 20, a temperature and humidity sensor 30, and a control module 40. In addition, a gateway 50 can be installed in at least a part of the plurality of regions 10a, 10b, i.e., the region 10b. On the other hand, although Figure 1 not shown in the figure, an access point 60 can also be installed in a specific region of the plurality of regions 10a, 10b (see Figure 2 ).

[0034] Hereinafter, the region 10b in which the gateway 50 is installed will be assumed as the target region 10 to describe the present invention.

[0035] Figure 2 is a diagram showing a brief configuration of a heating and cooling air conditioner control system 2 according to an embodiment of the present invention.

[0036] See Figure 2 , the heating and cooling 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.

[0037] 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.

[0038] The temperature and humidity sensor 30 can be installed at a position where the temperature and humidity of the area where people mainly move can be measured, but it is not limited thereto. The temperature and humidity sensor 30 can also be built into the heating and cooling air conditioner 20.

[0039] The temperature and humidity sensor 30 can communicate with other electronic devices in the target area 10. To this end, the temperature and humidity sensor 30 can include a short-range communication module. For example, the temperature and humidity sensor 30 can have a Bluetooth communication module, but the present invention is not limited thereto.

[0040] The control module 40 can be a device for transmitting a drive control signal for controlling the drive of the heating and cooling air conditioner 20 to the heating and cooling air conditioner 20. The control module 40 can be installed in a specific part of the target area 10 adjacent to the heating and cooling air conditioner 20. As described below, the drive control signal is generated by the management server 70 and can be transmitted from the management server 70 to the control module 40 through the access point 60 and the gateway 50.

[0041] To this end, the control module 40 can include a short-range communication module and an infrared data association (IrDA) module. For example, the control module 40 can have a Bluetooth communication module, but the present invention is not limited thereto.

[0042] The gateway 50 can communicate with the temperature and humidity sensor 30, the control module 40, and the access point 60 respectively. To this end, the gateway 50 can 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. For example, the first short-range communication module can be a Bluetooth communication module, and the second short-range communication module can be a WiFi (Wireless fidelity) communication module, but the present invention is not limited thereto.

[0043] The gateway 50 can transmit the indoor temperature and humidity information received from the temperature and humidity sensor 30 to the access point 60. In addition, the gateway 50 can receive the drive control signal of the heating and cooling air conditioner 20 described below from the access point 60 and then transmit it to the control module 40. In addition, the gateway 50 can also receive the drive-related data of the heating and cooling air conditioner 20 from the control module 40.

[0044] The access point 60 can relay communication 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 remote communication module.

[0045] The management server 70 can be a device that actually controls the heating and cooling air conditioner 20. The management server 70 can be communicatively connected to the access point 60 and the weather server 80. The management server 70 can receive indoor temperature and humidity information of the target area 10 from the access point 60, and can receive weather information of the target area 10 from the weather server 80. The management server 70 can generate a drive control signal for the heating and cooling air conditioner 20 by using the indoor temperature and humidity information and the weather information of the target area 10, and transmit the drive control signal to the access point 60.

[0046] The weather server 80 can be a server that provides weather information (meteorological information) by administrative region. The weather information can be predicted information. The weather information can include outdoor temperature, cloud cover, precipitation probability, humidity, etc.

[0047] On the other hand, in order to include the indoor temperature of each location in the target area 10 within the comfortable temperature range, one or more of the plurality of heating and cooling air conditioners 20 can be driven in combination. The management server 70 that calculates the combined expected temperature of one or more heating and cooling air conditioners 20 in the case of driving one or more heating and cooling air conditioners 20 in combination and calculates basic relationship information based on basic information measured in the case of driving one or more heating and cooling air conditioners 20 at the set combined expected temperature will be described in more detail below.

[0048] Figure 3 is a diagram showing a brief configuration of the management server 70 according to an embodiment of the present invention, Figure 4 briefly shows Figure 1 a diagram of the target area 10 in Space 1.

[0049] Here, three heating and cooling air conditioners 20 (20a, 20b, 20c) and four temperature and humidity sensors 30 (30a, 30b, 30c, 30d) are installed in the target area 10. On the other hand, the number of heating and cooling air conditioners 20 and temperature and humidity sensors 30 installed in the target area 10 is not limited to Figure 4 , and for ease of explanation, the "temperature and humidity sensor 30" is referred to as the "temperature sensor 30".

[0050] See Figure 3 , the management server 70 can include a communication unit 710, a control unit 720, and a storage unit 730.

[0051] Hereinafter, the functions of each component will be described in detail.

[0052] The communication unit 710 may be a module that communicates with the access point 60. For example, the communication unit 710 may include a remote communication module implemented by wire or wirelessly, but the present invention is not limited thereto.

[0053] As described above, the communication unit 710 may receive the indoor temperature information and indoor humidity information measured by the plurality of temperature sensors 20 through the access point 60.

[0054] The control unit 720 may include a memory and a processor. The memory may be a 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.

[0055] The control unit 720 may control the communication unit 710 and may generate drive control signals for the plurality of air conditioners 20. Here, the drive control signal may be a first drive control signal for controlling the drive (i.e., test drive) of one or more of the plurality of air conditioners 20 on a test day, or may be a second drive control signal for controlling the drive of one or more of the plurality of air conditioners 20 on a target day.

[0056] In addition, the control unit 720 may set a combined desired temperature for one or more of the plurality of air conditioners 20 based on the test drive of one or more of the plurality of air conditioners 20. Here, the combined desired temperature of each of the one or more air conditioners 20 may be the desired temperature of each of the one or more air conditioners 20 when the one or more air conditioners 20 are driven in combination. For example, when two of the three air conditioners 20a, 20b are driven and one air conditioner 20c is not driven, a combined desired temperature may be set for the two air conditioners 20a, 20b, and no combined desired temperature may be set for the one air conditioner 20c. By using the combined desired temperature of one or more air conditioners 20, the indoor temperature at each location in the target area 10 reaches the comfortable temperature range and unnecessary driving of the air conditioners 20 can be prevented. For example, each location in the target area 10 may be the installation location of the plurality of temperature sensors 30 in the target area 10.

[0057] In addition, the control unit 720 may calculate basic relationship information based on the combined desired temperature of one or more air conditioners 20, and may predict the temperature change amount in the target area 10 when one or more air conditioners 20 are turned on at the combined desired temperature. Here, the basic relationship information may be defined as the relationship information between the indoor and 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 driven at the combined desired temperature.

[0058] The storage unit 730 can store various information related to the drive control of the air conditioner 20.

[0059] First, the concepts of the comfortable temperature range and the thermal influence degree of the air conditioner 20 will be defined below, and then the operations performed in the management server 70 will be described in detail with reference to Figure 5 etc.

[0060] 1. Comfort temperature range

[0061] The comfortable temperature range can be defined as the body-sensation temperature range in which the users located in the target area 10 feel comfortable.

[0062] The comfortable temperature range can be set in the form of a temperature interval. For example, the comfortable temperature range can be set to "23.5°C to 24.5°C".

[0063] The comfortable temperature range can be set according to seasons. For example, the comfortable temperature range in summer can be higher than that in winter.

[0064] The comfortable temperature range can be set according to the time periods included in a specific day. Here, the multiple time periods can refer to the consecutive time periods included in the target day. The multiple time periods can be set based on the operation plan of the target area 10.

[0065] Various settings can be made for the unit time defined by the time period length. For example, the unit time can be set to 1 hour. Therefore, the comfortable temperature range for the time period "7:00 to 7:59" and the comfortable temperature range for the time period "8:00 to 8:59" can be set separately.

[0066] On the other hand, a temperature range other than the comfortable temperature range, that is, an uncomfortable temperature range, can be defined. At this time, the first uncomfortable temperature range and the second uncomfortable temperature range can be defined based on the comfortable temperature range.

[0067] Here, the first uncomfortable temperature range can be defined as the temperature range with a higher cooling / heating load than the comfortable temperature range, and the second uncomfortable temperature range can be defined as the temperature range with a lower cooling / heating load than the comfortable temperature range.

[0068] That is, the first uncomfortable temperature range can have a temperature higher than the comfortable temperature range in the cooling mode of the air conditioner 20, and can have a temperature lower than the comfortable temperature range in the heating mode of the air conditioner 20. The second uncomfortable temperature range can have a temperature lower than the comfortable temperature range in the cooling mode of the air conditioner 20, and can have a temperature higher than the comfortable temperature range in the heating mode of the air conditioner 20.

[0069] For example, when the air conditioner 20 is driven in cooling mode and the comfortable temperature zone in summer is set to "23.5°C~24.5°C", the first uncomfortable temperature zone may be a temperature zone above 24.6°C, and the second uncomfortable temperature zone may be a temperature zone below 23.4°C. For another example, when the air conditioner 20 is driven in heating mode and the comfortable temperature zone in winter is set to "25.5°C~26.5°C", the first uncomfortable temperature zone may be a temperature zone below 25.4°C, and the second uncomfortable temperature zone may be a temperature zone above 26.6°C.

[0070] 2. Heat impact degree of the heating and cooling air conditioner 20

[0071] The heat impact of the air conditioner 20 may be defined as the impact on the indoor temperature of the target area 10. That is, the installation location, cooling capacity, power consumption, energy efficiency, etc. of each air conditioner 20 installed in the target area 10 may be different from each other, so the heat impact of the air conditioner 20 may be different from each other.

[0072] The heat impact of each air conditioner 20 can be achieved by performing the following Figure 5 The steps are pre-set by the management server 70. In particular, the management server 70 can set the air conditioner 20 with the greatest thermal impact on the indoor temperature of the target area 10 as the most prioritized air conditioner 20.

[0073] The heat influence degree of the cooling and heating air conditioner 20 may be set based on at least one of the first heat influence degree and the second heat influence degree.

[0074] The first thermal impact of the air conditioner 20 may correspond to the degree of uniformly changing the indoor temperature of each location in the target area 10. In other words, the first thermal impact of the air conditioner 20 may correspond to the degree indicating how the indoor temperature change amount of each location in the target area 10 is dispersed when the air conditioner 20 is driven. Here, each location may include a plurality of installation locations of the temperature and humidity sensors 30.

[0075] The first heat influence of the air conditioner 20 and the dispersion degree of the indoor temperature variation at each location of the target area 10 may have an inverse relationship. That is, the greater the first heat influence of the air conditioner 20, the smaller the dispersion degree of the indoor temperature variation at each location of the target area 10, and the smaller the first heat influence of the air conditioner 20, the greater the dispersion degree of the indoor temperature variation at each location of the target area 10.

[0076] The second heat influence degree of the heating and cooling air conditioner 20 can correspond to the degree of changing the overall indoor temperature of the target area 10 to be changed. In other words, the second heat influence of the heating and cooling air conditioner 20 can correspond to the change amount of the overall indoor temperature of the target area 10 when the heating and cooling air conditioner 20 is driven.

[0077] The greater the second heat influence degree of the heating and cooling air conditioner 20, the greater the change amount of the overall indoor temperature of the target area 10, and the overall indoor temperature of the target area 10 can change rapidly. In addition, the smaller the second heat influence degree of the heating and cooling air conditioner 20, the smaller the change amount of the overall indoor temperature of the target area 10, and the overall indoor temperature of the target area 10 can change slowly.

[0078] For example, the heat influence degree of the heating and cooling air conditioner 20 can correspond to the sum of the value obtained by adding the first heat influence value and the first weighting value and the value obtained by adding the second heat influence value and the second weighting value. The first weighting value and the second weighting value can be set differently based on the driving mode of the heating and cooling air conditioner (for example, energy-saving mode, energy equalization mode, etc.).

[0079] Hereinafter, the "heat influence degree" will be labeled as the "influence degree".

[0080] 3. Set the combined desired temperature and calculate the corresponding basic relationship information

[0081] Figure 5 It is the overall flowchart of the method for calculating the basic relationship information of the target area 10 according to an embodiment of the present invention.

[0082] As described above, the method for calculating the basic relationship information of the target area 10 can be executed in the management server 70.

[0083] Hereinafter, the executed process will be described in detail for each step. Here, it is assumed that the temperature sensor 20 is the temperature sensor 30 to describe this embodiment.

[0084] In step S10, the management server 70 can set a combined desired temperature so that both the indoor temperature of the target area 10 and the indoor temperature of the temperature sensor 30 are included in the comfortable temperature region, and the combined desired temperature is the desired temperature of each of one or more heating and cooling air conditioners 20 that are combined and driven in the heating and cooling air conditioner 20 installed in the target area 10.

[0085] Among them, the indoor temperature of the target area 10 can correspond to the overall indoor temperature of the target area 10, and the indoor temperature of the temperature sensor 30 can correspond to the indoor temperature of each location where the temperature sensor 30 is installed.

[0086] Step S10 can be executed during a specific time period on the test day.

[0087] Hereinafter, referring to Figure 6 The detailed process of step S10 will be described in detail.

[0088] Figure 6 is a diagram showing Figure 5 the flowchart of step S10.

[0089] In step S11, the management server 70 may set the desired temperature of the top-priority heating and cooling air conditioner 20 that achieves the indoor temperature of the target area 10 most similar to the comfortable temperature area as the combined desired temperature of the top-priority heating and cooling air conditioner 20.

[0090] Here, the indoor temperature of the target area 10 most similar to the comfortable temperature area may be the indoor temperature of the target area 10 included in the comfortable temperature area, or may be the indoor temperature of the target area 10 included in the first non-comfortable temperature area and closest to the comfortable temperature area.

[0091] Figure 7 is a diagram showing Figure 6 the flowchart of step S11. The processes performed in each step are described below.

[0092] In step S1101, the management server 70 may control the top-priority heating and cooling air conditioner 20 to be tested and driven by the default test desired temperature. Therefore, the top-priority heating and cooling air conditioner 20 can be tested and driven.

[0093] For example, the driving time for the test drive may be 40 minutes or more, and the preset default test desired temperature may be 24°C during the first test drive.

[0094] In step S1102, the management server 70 may determine whether the indoor temperature of the target area 10 in the current test is included in the first non-comfortable temperature area. When the indoor temperature of the target area 10 is included in the first non-comfortable temperature area, steps S1105 to S1108 may be executed. When the indoor temperature of the target area 10 is not included in the first non-comfortable temperature area, step S1103 may be executed.

[0095] On the other hand, the indoor temperature of the target area 10 may correspond to the average value of the indoor temperatures measured by the respective temperature sensors 30 installed in the target area 10. In addition, the indoor temperature of the target area 10 may be the convergence value of the indoor temperatures directly measured by the temperature sensors 30. That is, when the heating and cooling air conditioner 20 continues to be driven at a specific desired temperature, the indoor temperature of the target area 10 has the characteristic of decreasing by a certain value and then remaining unchanged. Therefore, the converged indoor temperature may correspond to the indoor temperature of the target area 10 that remains unchanged, which can be inferred based on the change rate of the indoor temperature of the target area 10 during the test drive. On the other hand, 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.

[0096] When the indoor temperature of the target area 10 is included in the first discomfort temperature area, in step S1105, the management server 70 can determine whether the indoor temperature of the target area 10 in the previous test was included in the second discomfort temperature area.

[0097] If the indoor temperature of the target area 10 in the previous test was not included in the second discomfort temperature area, then in step S1106, the management server 70 can change the test expected temperature of the most priority heating and cooling air conditioner 20 by the amount of the unit temperature (e.g., 0.5 °C or 1 °C) in the direction of increasing the power consumption of the most priority heating and cooling air conditioner 20, and in step S1107, can test-drive the most priority heating and cooling air conditioner 20 with the changed test expected temperature of the most priority heating and cooling air conditioner 20. After that, step S1102 can be executed again. On the other hand, in the case where the current test is the first test, there is no previous test, so step S1106 can be executed.

[0098] Specifically, when the cooling mode of the heating and cooling air conditioner 20 is driven, the direction of increasing the power consumption of the most priority heating and cooling air conditioner 20 can correspond to the amount of reducing the test expected temperature of the heating and cooling air conditioner 20 by the unit temperature. In addition, when the heating mode of the heating and cooling air conditioner 20 is driven, the direction of increasing the power consumption of the most priority heating and cooling air conditioner 20 can correspond to the amount of increasing the test expected temperature of the heating and cooling air conditioner 20 by the unit temperature.

[0099] On the contrary, when the indoor temperature of the target area 10 in the previous test was included in the second discomfort temperature area, in step S1108, the management server 70 can set the test expected temperature of the most priority heating and cooling air conditioner 20 in the current test as the combined expected temperature of the most priority heating and cooling air conditioner 20.

[0100] On the other hand, when the indoor temperature of the target area 10 is not included in the first discomfort temperature area, in step S1103, the management server 70 can determine whether the indoor temperature of the target area 10 is included in the second discomfort temperature area. When the indoor temperature of the target area 10 is included in the second discomfort temperature area, steps S1107, S1109, and S1110 can be executed. When the indoor temperature of the target area 10 is not included in the second discomfort temperature area, step S1104 can be executed.

[0101] If the indoor temperature in the target area 10 in the previous test is not included in the first uncomfortable temperature area, the management server 70 can change the amount of the unit temperature of the test expected temperature of the most-priority heating and cooling air conditioner 20 in the direction of reducing the power consumption of the most-priority heating and cooling air conditioner 20 in step S1110, and can test and drive the most-priority heating and cooling air conditioner 20 with the changed test expected temperature of the most-priority heating and cooling air conditioner 20 in step S1107. After that, step S1102 can be executed again. On the other hand, in the case where the current test is the first test, since there is no previous test, step S1109 can be executed.

[0102] Specifically, when the cooling mode of the heating and cooling air conditioner 20 is driven, the direction of reducing the power consumption of the most-priority heating and cooling air conditioner 20 can correspond to the amount of increasing the test expected temperature of the heating and cooling air conditioner 20 by one unit temperature. In addition, when the heating mode of the heating and cooling air conditioner 20 is driven, the direction of reducing the power consumption of the most-priority heating and cooling air conditioner 20 can correspond to the amount of decreasing the test expected temperature of the heating and cooling air conditioner 20 by one unit temperature.

[0103] On the contrary, when the indoor temperature in the target area 10 in the previous test is included in the first uncomfortable temperature area, in step S1111, the management server 70 can set the test expected temperature of the most-priority heating and cooling air conditioner 20 in the previous test as the combined expected temperature of the most-priority heating and cooling air conditioner 20.

[0104] On the other hand, when the indoor temperature in the target area 10 is not included in the second uncomfortable temperature area, it corresponds to the indoor temperature in the target area 10 being included in the comfortable temperature area. Therefore, in step S1104, the management server 70 can set the test expected temperature of the most-priority heating and cooling air conditioner 20 in the current test as the combined expected temperature of the most-priority heating and cooling air conditioner 20.

[0105] On the other hand, step S1102 and step S1103 can correspond to the step of determining whether the indoor temperature in the target area 10 is included in the comfortable temperature area. In addition, step S1106 and step S1110 can correspond to the step of changing the amount of the unit temperature of the test expected temperature of the most-priority heating and cooling air conditioner 20.

[0106] Hereinafter, Figure 7 an example will be described by dividing it into a cooling mode and a heating mode. Here, it is assumed that the unit temperature is 1 °C.

[0107] a) Driving of the cooling mode of the heating and cooling air conditioner 20

[0108] When the comfortable temperature range on the test day is set to 24.5°C to 25.5°C, the test expected temperature of the most preferred heating and cooling air conditioner 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 test expected temperature of 24°C of the most preferred heating and cooling air conditioner 20 in the current test (the first test) as the combined expected temperature of the most preferred heating and cooling air conditioner 20 through "Step S1102 -> Step S1103 -> Step S1104".

[0109] In addition, when the comfortable temperature range on the test day is set to 23.5°C to 24.5°C, the test expected temperature of the most preferred heating and cooling air conditioner 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 drives are executed. Through Step S1102 -> Step S1105 -> Step S1106 -> Step S1107 -> Step S1102 -> Step S1103 -> Step S1109 -> Step S1111, the management server 70 can set the test expected temperature (24°C) of the most preferred heating and cooling air conditioner 20 in the previous test (the first test) as the combined expected temperature of the most preferred heating and cooling air conditioner 20.

[0110] In addition, when the comfortable temperature range on the test day is set to 23.5°C to 24.5°C, the test expected temperature of the most preferred heating and cooling air conditioner 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 drives are executed. Through Step S1102 -> Step S1103 -> Step S1109 -> Step S1110 -> Step S1107 -> Step S1102 -> Step S1105 -> Step 1108, the management server 70 can set the test expected temperature (24°C) of the most preferred heating and cooling air conditioner 20 in the current test (the second test) as the combined expected temperature of the most preferred heating and cooling air conditioner 20.

[0111] b) Driving of the heating mode of the heating and cooling air conditioner 20

[0112] When the comfortable temperature range on the test day is set to 25.8°C to 26.3°C, the test expected temperature of the most preferred heating and cooling air conditioner 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 test expected temperature (26°C) of the most preferred heating and cooling air conditioner 20 in the current test (the first test) as the combined expected temperature of the most preferred heating and cooling air conditioner 20 through "Step S1102 -> Step S1103 -> Step S1104".

[0113] In addition, when the comfortable temperature range on the test day is set to 26.2°C to 26.7°C, the test expected temperature of the most preferred heating and cooling air conditioner 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 drives are executed. Through steps S1102 -> step S1105 -> step S1106 -> step S1107 -> step S1102 -> step S1103 -> step S1109 -> step S1111, the management server 70 can set the test expected temperature (26°C) of the most preferred heating and cooling air conditioner 20 in the previous test (the first test) as the combined expected temperature of the most preferred heating and cooling air conditioner 20.

[0114] In addition, when the comfortable temperature range on the test day is set to 26.2°C to 26.7°C, the test expected temperature of the most preferred heating and cooling air conditioner 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 drives are executed. Through steps S1102 -> step S1103 -> step S1109 -> step S1110 -> step S1107 -> step S1102 -> step S1105 -> step 1108, the management server 70 can set the test expected temperature (26°C) of the most preferred heating and cooling air conditioner 20 in the current test (the second test) as the combined expected temperature of the most preferred heating and cooling air conditioner 20.

[0115] In summary, in step S11, the management server 70 can, based on at least one test drive of the most preferred heating and cooling air conditioner 20, set the expected temperature of the most preferred heating and cooling air conditioner 20 that achieves the indoor temperature of the target area 10 most similar to the comfortable temperature range of the target area 10 as the combined expected temperature of the most preferred heating and cooling air conditioner 20. The combined expected temperature of the most preferred heating and cooling air conditioner 20 can be used when more than one heating and cooling air conditioner 20 is driven in combination.

[0116] See again Figure 6 , after setting the combined expected temperature of the most preferred heating and cooling air conditioner 20, in step S12, the management server 70 can determine whether the indoor temperature of each individual temperature sensor is included in the comfortable temperature range.

[0117] That is, due to the different installation positions of the temperature sensors 30, the indoor temperatures measured by the respective temperature sensors 30 may be different. Therefore, the indoor temperatures of some of the temperature sensors 30 may be included in the comfortable temperature range, while the indoor temperatures of some other temperature sensors 30 may not be included in the comfortable temperature range. This situation may occur regardless of whether the indoor temperature of the entire target area 10 is included in the comfortable temperature range. The object of the present invention is to include the indoor temperatures of all locations in the target area 10 in the comfortable temperature range. To achieve this object, step S12 can be executed.

[0118] When the indoor temperatures of the individual temperature sensors are not included in the comfortable temperature range, that is, when the indoor temperatures of at least some of the temperature sensors 30 in the temperature sensor 30 are included in the first non-comfortable temperature range or the second non-comfortable temperature range, step S12 can be executed after executing steps S13 to S15.

[0119] Specifically, in step S13, the management server 70 can calculate the ranking information of the temperature sensor 30 based on the indoor temperature of the individual temperature sensors and the comfortable temperature range.

[0120] According to the embodiment, the management server 70 can sort the indoor temperatures of the individual temperature sensors in descending order according to the difference value between the indoor temperature of the temperature sensor 30 and the comfortable temperature range, and calculate the ranking information of the temperature sensor 30 based on the sorted indoor temperatures of the individual temperature sensors 30.

[0121] In step S14, the management server 70 can select the first heating and cooling air conditioner 20 that has the temperature sensor influence degree ranking information most similar to the ranking information of the temperature sensor 30 among the heating and cooling air conditioners 20 that have not been set with the combined desired temperature.

[0122] Here, referring to Figure 6 , since steps S12 to S16 are repeatedly executed, the heating and cooling air conditioner 20 that has not been set with the combined desired temperature can refer to the heating and cooling air conditioner 20 other than the above-mentioned highest-rank heating and cooling air conditioner 20 that has been set with the combined desired temperature.

[0123] According to the embodiment, the management server 70 can compare the similarity between the temperature sensor influence degree ranking information of the heating and cooling air conditioner 20 that has not been set with the combined desired temperature and the ranking information of the temperature sensor 30 based on a known similarity comparison algorithm to select the first heating and cooling air conditioner 20.

[0124] For example, in Figure 4In the environment shown, when the cooling and heating air conditioner a 20a is the most prioritized cooling and heating air conditioner 20 set with a combined desired temperature, the cooling and heating air conditioners 20 not set with the combined desired temperature can be the cooling and heating air conditioner b 20b and the cooling and heating air conditioner c 20c. At this time, assuming that the ranking information of the temperature sensors 30 is "b, c, d, a", the influence degree ranking information of the temperature sensor of the cooling and heating air conditioner b 20b is "b, d, c, a", and the influence degree ranking information of the temperature sensor of the cooling and heating air conditioner c 20c is "c, d, b, a". On the other hand, a, b, c, and d respectively represent the temperature sensor a 30a, the temperature sensor b 30b, the temperature sensor c 30c, and the temperature sensor d 30d. Assuming that the indoor temperatures of the temperature sensor b 30b and the temperature sensor c 30c are not included in the comfortable temperature range. In this case, the management server 70 can calculate the cooling and heating air conditioner b 20b as the first cooling and heating air conditioner 20.

[0125] In short, step S14 can correspond to the step of selecting, among the cooling and heating air conditioners 20 not set with the combined desired temperature, the first cooling and heating air conditioner having the influence degree of the individual temperature sensor most similar to the indoor temperature of the individual temperature sensor when the indoor temperature of at least a part of the temperature sensors 30 is not included in the comfortable temperature range while the cooling and heating air conditioner 20 set with the combined desired temperature is driven at the corresponding combined desired temperature.

[0126] In step S15, when the management server 70 drives the cooling and heating air conditioner 20 set with the combined desired temperature at the corresponding combined desired temperature, it can set the desired temperature of the first cooling and heating air conditioner 20 that can achieve the indoor temperature of the target area 10 most similar to the comfortable temperature range as the combined desired temperature of the first cooling and heating air conditioner 20.

[0127] Figure 8 is a diagram showing Figure 6 the flowchart of step S15.

[0128] Refer to Figure 8 , step S15 can be executed similarly to step S11 of the above Figure 7 . That is, in steps S1501 and S1507, except that the cooling and heating air conditioner 20 set with the combined desired temperature during the test drive is driven together, Figure 8 steps S1501 to S1511 of Figure 7 correspond to steps S1101 to S1111 of

[0129] In summary, step S15 can be a step of testing and driving the first heating and cooling air conditioner 20 at least once to set the combined desired temperature of the first heating and cooling air conditioner 20 that can achieve the indoor temperature of the target area 10 most similar to the comfortable temperature area when the heating and cooling air conditioner 20 with the combined desired temperature set is driven at the corresponding combined desired temperature.

[0130] Referring again to Figure 6 , step S12 can be executed again after step S15 is executed. That is, the management server 70 can re-determine whether the indoor temperatures of the individual temperature sensors are each included in the comfortable temperature area.

[0131] On the other hand, when the indoor temperatures of the individual temperature sensors are each included in the comfortable temperature area, in step S16, the management server 70 can complete the setting of the combined desired temperature for each of the one or more heating and cooling air conditioners 20 driven in combination. At this time, it can be set that the heating and cooling air conditioner 20 for which the combined desired temperature is not set is not driven.

[0132] That is, i) when the indoor temperatures of the temperature sensors 30 in the target area 10 are all included in the comfortable temperature area when the most priority heating and cooling air conditioner 20 is driven at the corresponding combined desired temperature, it can be set that only the most priority heating and cooling air conditioner 20 is driven at the corresponding combined desired temperature, ii) when at least a part of the indoor temperatures of the temperature sensors 30 are not included in the comfortable temperature area when the most priority heating and cooling air conditioner 20 is driven at the corresponding combined desired temperature, it can be set that the most priority heating and cooling air conditioner 20 and at least a part of the heating and cooling air conditioners 20 are driven at the corresponding combined desired temperatures respectively, iii) it can be set that the heating and cooling air conditioners 20 other than the most priority heating and cooling air conditioner 20 and at least a part of the heating and cooling air conditioners 20 are not driven.

[0133] The above content is sorted out as follows:

[0134] The indoor temperature of the target area 10 can correspond to the average value of the individual indoor temperatures measured by the temperature sensors 30 respectively. In this case, even if the indoor temperature of the target area 10 is included in the comfortable temperature area, it is possible that some individual indoor temperatures are not included in the comfortable temperature area. Therefore, the management server 20 can make the indoor temperature of the target area 10 approach the comfortable temperature area based on the driving of the most priority heating and cooling air conditioner 20, and when there are some individual indoor temperatures not included in the comfortable temperature area, it can further drive only some of the heating and cooling air conditioners 20 that have a great influence on the individual indoor temperatures. Therefore, unnecessary driving of the heating and cooling air conditioners 20 can be prevented, excessive cooling or heating occurring at some locations can be prevented, and while the indoor temperatures at each location in the target area 10 satisfy the comfortable temperature area, the power consumption of the heating and cooling air conditioners 20 can be minimized to the greatest extent.

[0135] Referring again toFigure 5 In step S20, the management server 70 can collect the basic information measured when one or more heating and cooling air conditioners 20 are driven at corresponding combined desired temperatures.

[0136] Step S20 can be executed at a specific time period on an additional test day after the test day.

[0137] The basic information can be information on the temperature change amount of the target area 10 based on the indoor and outdoor temperature difference of the target area 10 when one or more heating and cooling air conditioners 20 are driven at the above-mentioned combined desired temperatures.

[0138] The indoor and outdoor temperature difference of the target area 10 can correspond to the difference T o -T i between the outdoor temperature of the target area 10 and the indoor temperature of the target area 10. Here, the outdoor temperature of the target area 10 can be collected from the meteorological server 80, and the indoor temperature of the target area 10 can be measured by the temperature sensor 30.

[0139] The temperature change amount of the target area 10 can be defined as the temperature change amount per unit time of the target area 10. For example, the unit time can be 1 hour, but the present invention is not limited thereto.

[0140] The basic information can be collected at a preset period. For example, when the length of the late-night time period is 1 hour, the basic information can be collected in units of 10 minutes.

[0141] In step S30, the management server 70 can calculate the basic relationship information of the target area 10 based on the basic information.

[0142] The basic relationship information can be defined as the relationship information between the indoor and outdoor temperature difference of the target area 10 and the temperature change amount of the target area 10 when one or more heating and cooling air conditioners 20 are driven.

[0143] According to an embodiment, the basic relationship information can be represented by a basic relationship function corresponding to a trend line regarding a plurality of basic information. According to an embodiment, the trend line can be a polynomial trend line, and in particular, a quadratic polynomial trend line. That is, the basic relationship information can correspond to a basic relationship polynomial function that outputs the temperature change amount of the target area 10 with the indoor and outdoor temperature difference of the target area 10 as a variable. Here, the basic relationship information can be set separately in the cooling mode and the heating mode of the heating and cooling air conditioner 20.

[0144] According to an embodiment, in the cooling mode and the heating mode, the function values of the basic relationship polynomial can be as shown in the following Mathematical Formula 1:

[0145]

Mathematical Formula 1

[0146]

[0147] Here, βT D（o-i） represents the indoor-outdoor temperature difference of the target area 10, f(βT D（o-i） ) represents the temperature change amount of the target area 10, a and b represent the coefficients of the variable terms defined by the thermal characteristic parameters of the target area 10, and c represents the constant term defined by the thermal characteristic parameters of the target area 10.

[0148] On the other hand, the basic relationship information can be used to predict the temperature change amount of the target area 10 on the target day. In particular, the management server 70 can reflect weather information (e.g., cloud cover information) of the target day into the basic relationship information to calculate the target relationship information, and predict the temperature change amount of the target area 10 based on the target relationship information.

[0149] In short, the temperature change amount information of the target area 10 can be accurately predicted by calculating the basic relationship information of the target area 10 when one or more of the heating and cooling air conditioners 20 are driven.

[0150] On the other hand, the above content can also be executed in the control module 40 instead of in the management server 70. In this case, the control module 40 includes a control unit based on a high-performance processor, and may further include the above-mentioned second short-range communication module and infrared communication module. The control module 40 can obtain the weather information of the target area 10 from the meteorological server 80 through the access point 60 and the gateway 50, and can obtain the indoor temperature and humidity of the target area 10 measured by the temperature and humidity sensor 30 through the gateway 50. In addition, the temperature and humidity sensor 30 and the control module 40 can be built into the heating and cooling air conditioner 20. In this case, the control module 40 can also directly obtain the indoor temperature and humidity from the temperature and humidity sensor 30. The execution operation of the control module 40 is similar to the above description, so the detailed description is omitted.

[0151] In addition, embodiments of the present invention can be implemented in the form of program instructions that can be run on various computer devices and recorded in a computer-readable medium. The computer-readable medium may include one or a combination of program instructions, data files, data structures, etc. The program instructions recorded in the medium may be specifically designed and configured for the present invention or may be well-known and used by those of ordinary skill in the computer software field.

Examples of program instructions include not only machine code created by a compiler but also high-level language code that can be run by a computer using a demodulator, etc. The above hardware devices can be configured to work as more than one software module to perform the operations of an embodiment of the present invention, and vice versa.
