Description

Apparatus and method for calculating the thermal influence of a plurality of air conditioners and heaters installed in the target area

Embodiments of the present invention relate to an apparatus and method for calculating the thermal influence of a plurality of air conditioners and heaters installed in a target area.

An air conditioner (or air conditioner) is a device that uses a refrigeration cycle to maintain a comfortable indoor temperature suitable for human activity. An air conditioner cools the room by taking in hot indoor air, exchanging heat with a low-temperature refrigerant, and discharging it into the room, or heating the room by doing the opposite.

Generally, the operation of air conditioners is controlled by direct human operation. For example, in summer, when the indoor temperature is high, the user turns on the air conditioner and sets the desired temperature of the turned on air conditioner low to quickly reduce the high indoor temperature.

Meanwhile, many users are located in spaces such as restaurants, cafes, and offices, and the manager of the space generally directly controls the operation of the air conditioner. However, there is a problem in which the air conditioner does not operate efficiently due to the manager's ignorance or indifference.

For example, in summer, if the administrator sets the desired temperature of the air conditioner to high, users may feel hot, and if the administrator sets the desired temperature of the air conditioner to low, users may feel cold. Accordingly, users feel uncomfortable. Moreover, when the desired temperature of the air conditioner is set low in the summer, the power consumption of the air conditioner increases, thereby increasing the electricity cost of the space. Therefore, there is a need for technology that efficiently operates air conditioners and heaters without managers directly manipulating the air conditioners.

The purpose of the present invention is to provide an apparatus and method for calculating the thermal influence of an air conditioner (i.e., the first thermal influence), which is defined as the degree to evenly change the indoor temperature of each point of the target area.

In addition, an apparatus for calculating the thermal influence of a plurality of air conditioners and heaters installed in a target area according to another embodiment of the present invention includes a memory that stores computer-readable instructions, and a processor implemented to execute the instructions. At this time, the processor controls, for each of the plurality of periods, to drive a corresponding air conditioner of the period among the plurality of air conditioners, and for each of the plurality of periods, a plurality of the target areas according to the operation of the corresponding air conditioner. The indoor temperature change amount for each temperature sensor may be calculated, and the thermal influence of each of the plurality of air conditioners may be calculated based on the indoor temperature change amount for each of the plurality of temperature sensors for each of the plurality of periods.

According to the present invention, by calculating the thermal influence (i.e., first thermal influence) of a plurality of air conditioners, which is defined as the degree to which the indoor temperature at each point of the target area is evenly changed, is present in the target area when the plurality of air conditioners are subsequently operated. It has the advantage of allowing all users to efficiently adapt to the changed indoor temperature.

Here, three air conditioners (20: 20a, 20b, 20c) and three temperature and humidity sensors (30: 30a, 30b, 30c) 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 FIG. 4 .

Referring to FIG. 3, the management server 70 may include a communication unit 710, a control unit 720, and a storage unit 730.

Below, the function of each component will be described in detail.

The communication unit 710 may be a module that communicates with the access point 60. For example, the communication unit 710 may include a long-distance communication module implemented in a wired or wireless manner, but the present invention is not limited thereto.

As described above, the communication unit 710 may receive indoor temperature information and indoor humidity information measured by the plurality of temperature and humidity sensors 30 through the access point 60.

Meanwhile, the thermal influence of the plurality of air conditioners 20 is a first thermal influence that evenly changes the indoor temperature of each point within the target area 10 and a second thermal influence that significantly changes the overall indoor temperature in the target area 10. May include influence. For example, each point within the target area 10 may be an installation point of a plurality of temperature and humidity sensors 30 of the target area 10 .

The thermal influence of the air conditioner 20 may be set based on the indoor temperature values measured by the plurality of temperature and humidity sensors 30 on the test day. At this time, there may be multiple test days, and the test date may be one that precedes the target date.

The storage unit 730 may store various information related to driving control of the air conditioner 20.

Meanwhile, in order to set the thermal influence of the plurality of air conditioners 20, the concept of thermal characteristics of the target area 10 must be defined. In the following, the concept of thermal characteristics of the target area 10 that affects the indoor temperature of the target area 10 will first be explained, and an embodiment of setting the thermal influence of a plurality of air conditioners 20 will be described. .

1. Thermal characteristics of the target area (10)

The thermal characteristics of the target area 10 may be defined as the influence that environmental changes inside and outside the target area 10 have on changes in the indoor temperature of the target area 10. The thermal characteristics of the target zone 10 may be substantially different from those of other zones.

The thermal characteristics of the target area 10 may be defined by a plurality of thermal characteristic parameters. According to an embodiment, the plurality of thermal characteristic parameters may include at least one of sunlight, the human body, a power consuming device, immersion, ventilation, and a wall.

Sunlight (S5unlight) is light that naturally shines on the target area 10 through a window provided in the target area 10 without the user's intention.

The human body is a user located in the target area 10 and is a natural heating element that emits heat.

A power consumption device is an electrical/electronic device that uses power to perform a specific operation, and heat is emitted when the power consumption device is driven. As an example, the power consumption device may be a lighting device, personal computer (PC), refrigerator, water purifier, TV, humidifier, air purifier, dishwasher, etc. At this time, the air conditioner 20 is defined to be excluded from the power consumption devices. Meanwhile, base power consuming devices such as refrigerators, water purifiers, etc. may be always turned on without being turned off in the target area 10 to emit heat.

Air infiltration is outdoor air that flows into the target area (10) through gaps in windows or doors. In other words, the infiltrating air is external air that naturally flows into the target area 10 without the user's intention.

Ventilation is outdoor air that flows into the target area 10 due to an open window, operation of a ventilation device, etc. In other words, ventilation may be air exchange between indoor and outdoor air in the target area 10 according to the user's intention.

Wall structures include doors, windows, walls, etc. Heat inside the target area 10 may leak to the outside of the target area 10 by radiation/convection/conduction through the wall structure, and heat outside the target area 10 may radiate through the wall structure. It may flow into the interior of the target area 10 by /convection/conduction.

Meanwhile, the target area 10 may be an area where a specific activity is performed. For example, the target area 10 may be an office where office activity is performed, a cafe or restaurant where service activity (S5service activity) is performed, etc. Additionally, an activity schedule or preset activity hours is set in the target area 10. For example, office hours may be set in offices, and service hours (S5service hours) may be set in cafes, restaurants, etc. Activity time can be defined as including time to prepare for the activity.

At this time, when the activity time of the target area 10 ends, all users performing activities in the target area 10 can leave the target area 10, and power consumption devices except the base power consumption device turn. It may be turned off and ventilation may not be performed. In addition, during late night hours, sunlight does not enter the target area 10 and all of the heat stored in the wall structure may be released due to the thermal inertia of the wall structure.

That is, the indoor temperature of the target area 10 in the middle of the night is the heat caused by sunlight passing through the target area 10, the heat emitted from the human body located in the target area 10, and the power consumption that is turned off in the middle of the night. It may not be affected by at least one of the heat emitted from the device and the heat caused by the inflow of external air into the target area 10 due to ventilation. However, the indoor temperature of the target area 10 during late-night hours may be affected by heat emitted by the operation of the underlying power consumption device, heat due to the inflow of outside air due to infiltration, and heat associated with the wall structure.

Meanwhile, the late-night time zone may be set based on at least one of activity schedule information, sunrise time, and sunset time of the target area 10.

According to an embodiment, the late-night time zone may be a time period between a first time point and a second time point. The second time point may arrive after the first time point. At this time, the first time may correspond to the later of the end time of the activity time of the target area 10 and the sunset time, and the second time may correspond to the earlier of the start of the activity time of the target area 10 and the sunrise time. It can correspond to the point of view.

For example, the target area 10 is an office, the office's activity hours are from 9:00 to 18:00, the sunset time is 19:50, and the sunrise time (i.e., the next day's sunrise time) is 5:10. In this case, the first time point may be 19:50 (sunset time), and the second time point may be 5:10 (sunrise time). As another example, if the target area 10 is a cafe, the activity hours of the cafe are from 7:00 to 20:00, the sunset time is 17:31, and the sunrise time is 7:50, the first time point is 20:00. 00 (the end time of the activity time), and the second time point may be 7:00 (the start time of the activity time).

In addition, the late-night time zone may be a time period in which a predetermined time has elapsed after the activity time of the target area 10 ends. The late-night time zone may begin at a predetermined time after the control point has passed. At this time, all of the heat stored in the wall structure can be released at a predetermined time. For example, the length of the predetermined time may be 40 minutes, but the present invention is not limited thereto.

2. Calculate the thermal impact of a plurality of air conditioners (20) installed in the target area (10)

The method of calculating the thermal influence of the plurality of air conditioners 20 can be performed in the management server 70, and the thermal influence of the air conditioners 20 can be calculated based on the indoor temperature value measured on a preset test day. . In particular, the indoor temperature value may be an indoor temperature value measured during late night hours within the test day. The indoor temperature value can be measured by a plurality of temperature and humidity sensors 30 installed in the target area. Hereinafter, for convenience of explanation, the present invention will be described assuming that the plurality of air conditioners 20 are operated in a cooling mode.

FIG. 5 is a diagram illustrating the overall flowchart of a method for calculating the thermal influence of a plurality of air conditioners 20 according to the first embodiment of the present invention. Here, the thermal influence is a first thermal influence corresponding to the degree to which the indoor temperature of each point within the target area 10 is evenly changed.

Hereinafter, the process performed for each step will be described in detail.

In step S510, the management server 70 may control one air conditioner 20 to be operated for each of a plurality of periods. That is, for each of the plurality of periods, the air conditioner 20 (hereinafter referred to as “corresponding air conditioner”) corresponding to the period among the plurality of air conditioners 20 may be driven. Meanwhile, the corresponding air conditioner 20 for each of the plurality of periods may be operated. (20) may be set randomly. Additionally, the period during which the air conditioner 20 is driven may also be referred to as the “driving period.”

Specifically, the plurality of periods may be sequential periods included in the late night hours of the test day. A plurality of waiting periods may exist between the plurality of periods, and the number of the plurality of periods may be equal to the number of the plurality of air conditioners 20. The corresponding air conditioner 20 may be driven in each of the plurality of periods, and all of the plurality of air conditioners 20 may be non-driven in the plurality of standby periods. The plurality of periods may have the same length of time, and in each of the plurality of periods the corresponding air conditioner 20 may be driven to the same desired temperature, i.e., a default desired temperature.

Additionally, “driving the corresponding air conditioner 20” may correspond to an operation in which the corresponding air conditioner 20 is turned on and then turned off. That is, the corresponding air conditioner 20 may be turned on at the beginning of the period and turned off at the end of the period. And, “non-driving of the corresponding air conditioner 20” may correspond to the operation of maintaining the corresponding air conditioner 20 in a turned-off state.

FIG. 6 is a diagram illustrating a concept in which a plurality of air conditioners 20 are driven in a plurality of periods according to an embodiment of the present invention. At this time, as shown in FIG. 4, it is assumed that there are three plurality of air conditioners 20.

Referring to FIG. 6, the first air conditioner 20a, which is the corresponding air conditioner 20, is driven in the first period, and the indoor temperature value for each of the plurality of temperature and humidity sensors 30 measured in the first period is the first air conditioner 20a. It corresponds to the indoor temperature value for each of the plurality of temperature and humidity sensors 30 according to the operation of , and the “first period” corresponds to the “first air conditioner 20a.” Then, in the second period, the second air conditioner 20b, which is the corresponding air conditioner 20, is driven, and the indoor temperature values for each of the plurality of temperature and humidity sensors 30 measured in the second period are determined according to the operation of the second air conditioner 20b. It corresponds to the indoor temperature value for each of the plurality of temperature and humidity sensors 30, and the “second period” corresponds to the “second air conditioner 20b.” In addition, in the third period, the third air conditioner 20c, which is the corresponding air conditioner 20, is driven, and the indoor temperature values for each of the plurality of temperature and humidity sensors 30 measured in the third period are based on the operation of the third air conditioner 20c. It corresponds to the indoor temperature value for each of the plurality of temperature and humidity sensors 30, and the “third period” corresponds to the “third air conditioner 20c.”

As an example, the time length of each of the three periods may be 20 minutes, the time length of each of the three waiting periods may be 20 minutes, and the three air conditioners 20 are operated at a desired temperature of 24°C (default desired temperature). It can be.

Meanwhile, as described above, in the late-night hours, heat caused by sunlight passing through the target area 10, heat emitted from the human body located in the target area 10, and heat emitted from power consumption devices that are turned off in the late-night hours. , is not affected by at least one of the following: heat caused by the inflow of external air into the target area due to ventilation. Therefore, when the air conditioner 20 is operated in the middle of the night, the minimal influence of the external environment can be reflected in the indoor temperature of the target area 10, and a plurality of Each of the air conditioners 20 may be operated during late night hours. However, the present invention is not limited to this, and each of the plurality of air conditioners 20 may be operated even during daytime hours.

Referring again to FIG. 5 , in step S520, the management server 70 may obtain indoor temperature values measured for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods.

That is, as the corresponding air conditioner 20 is driven in each of the plurality of periods, each of the plurality of temperature and humidity sensors 30 can measure the indoor temperature value, and the measured indoor temperature value can be received by the management server 70. .

Figure 7 is a diagram showing indoor temperature values measured over a plurality of periods, according to an embodiment of the present invention.

Here, it is assumed that the target area 10 in FIG. 7 is the situation in FIGS. 4 and 6.

Referring to FIG. 7 , the indoor temperature value of the target area 10 may decrease as the corresponding air conditioner 20 is driven in each of a plurality of periods. And, as the plurality of air conditioners 20 are not operated in each of the plurality of waiting periods, the indoor temperature value of the target area 10 may increase.

Meanwhile, since the first air conditioner 20a is driven in the first period, the indoor temperature value measured by the first temperature and humidity sensor 30a, which has the closest thermal distance to the first air conditioner 20a, may decrease to the greatest extent. . Similarly, since the second air conditioner 20b is driven in the second period, the indoor temperature value measured by the second temperature and humidity sensor 30b, which has the closest thermal distance to the second air conditioner 20b, may decrease by the greatest extent. there is. In addition, since the third air conditioner 20c is operated in the third period, the indoor temperature value measured by the third temperature and humidity sensor 30c, which has the closest thermal distance to the third air conditioner 20b, may decrease to the greatest extent. .

In step S530, the management server 70 may calculate the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 in the target area 10 for each of the plurality of periods.

According to the embodiment, the amount of change in indoor temperature is the difference between the indoor temperature value measured by the temperature and humidity sensor 30 at the end of the period and the indoor temperature value measured by the temperature and humidity sensor 30 at the start of the period and can be responded to.

In step S540, the management server 70 may standardize the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods.

Specifically, since the outdoor temperature of the target area 10 changes in real time, the outdoor temperature of the target area 10 in each of the plurality of periods is different. In addition, since the thermal efficiencies of the plurality of air conditioners 20 are different from each other, the amount of heat released in the wall structure in the plurality of standby periods caused by the operation of the plurality of air conditioners 20 is different from each other. Due to the outdoor temperature of the target area 10 and the heat release amount stored in the wall structure, the indoor temperature value of the target area 10 measured in each of the plurality of periods is the target area 10 by driving the corresponding air conditioner 20. There is a problem in that it does not accurately reflect the indoor temperature value. Therefore, in the present invention, the above-mentioned problem can be solved by standardizing the amount of change in indoor temperature of the plurality of temperature and humidity sensors 30 for each of the plurality of periods.

According to an embodiment, the management server 70 selects a reference indoor temperature change amount among the indoor temperature change amounts for each of the plurality of temperature and humidity sensors 30 for each of a plurality of periods, and selects a plurality of temperature and humidity changes based on the selected reference indoor temperature change amount. The amount of indoor temperature change can be standardized for each sensor 30. By standardizing the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30, the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 can be corrected to a value between 0 and 1.

According to an embodiment, the standardized indoor temperature change amount of the yth temperature sensor among the plurality of temperature and humidity sensors 30 for the xth period among the plurality of periods may be expressed as Equation 1 below.

Here, ΔT _{i,xy,n is} the normalized indoor temperature change of _the yth temperature sensor for the Each refers to the standardized indoor temperature change amount.

According to the embodiment, the reference indoor temperature change amount for the corresponding period may correspond to the maximum indoor temperature change amount among the indoor temperature change amounts of each of the plurality of temperature and humidity sensors 30.

Referring to FIG. 7, the maximum indoor temperature change in the first period may be the indoor temperature change of the first temperature and humidity sensor 30a, and the maximum indoor temperature change in the second period may be the indoor temperature change of the second temperature and humidity sensor 30b. It may be the amount of change in indoor temperature, and the maximum amount of change in indoor temperature in the third period may be the amount of change in indoor temperature of the third temperature and humidity sensor 30c.

As an example, in the situation of FIG. 7, when the indoor temperature changes of the three temperature and humidity sensors 30a, 30b, and 30c in the first period are 2.5°C, 1.8°C, and 2.1°C, respectively, the maximum indoor temperature change may be the amount of change in indoor temperature of the first temperature and humidity sensor 30a. Then, the management server 70 subtracts the indoor temperature change amount of the three temperature and humidity sensors 30a, 30b, and 30c by the indoor temperature change amount of the first temperature and humidity sensor 30a to determine the indoor temperature change amount of the three temperature and humidity sensors 30a, 30b, and 30c. The amount of change in indoor temperature can be standardized. Therefore, the standardized indoor temperature change for each of the three temperature and humidity sensors (30a, 30b, 30c) is 1 (=2.5°C/2.5°C), 0.72 (=1.8°C/2.5°C), and 0.84 (=2.1°). C/2.5°C).

Table 1 is a table summarizing the standardized amount of indoor temperature change in the situation of FIG. 7, and FIG. 8 shows the standardized amount of indoor temperature change for each temperature and humidity sensor 30 for a plurality of periods in the situation of FIG. 7. In Table 1 and Figure 8, "AC" is the air conditioner (20), "S" is the temperature and humidity sensor (30), "ΔTi" is the amount of indoor temperature change, "ΔTi,N" is the standardized amount of indoor temperature change, and "max" is Each represents the maximum value.

In step S550, the management server 70 may calculate the first thermal influence of each of the plurality of air conditioners 20 based on the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods. there is. In particular, the management server 70 may calculate the first thermal influence of each of the plurality of air conditioners 20 based on the standardized amount of indoor temperature change.

As described above, the first thermal influence of the air conditioner 20 may correspond to the degree to which the indoor temperature of each point within the target area 10 is evenly changed. In other words, the first thermal influence of the air conditioner 20 may correspond to a degree indicating how the amount of indoor temperature change at each point within the target area 10 is distributed when the air conditioner 20 is driven. Here, each of the above points may include installation points of a plurality of temperature and humidity sensors 30.

The first thermal influence of the air conditioner 20 and the degree of dispersion of the indoor temperature change at each point of 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 dispersion of the indoor temperature change at each point of the target area 10, and the smaller the first thermal influence of the air conditioner 20, the smaller the degree of dispersion of the indoor temperature change at each point of the target area 10. ) The degree of dispersion of the indoor temperature change at each point may increase.

According to an embodiment, the management server 70 calculates the total or average value of the normalized indoor temperature changes for each of the plurality of temperature and humidity sensors 30 in the xth period among the plurality of periods to the air conditioner 20 corresponding to the xth period. It can be calculated as the first thermal influence.

Hereinafter, for convenience of explanation, the total amount of indoor temperature change standardized for each of the plurality of temperature and humidity sensors 30 is assumed to be the first thermal influence of the air conditioner 20.

As an example, referring to FIG. 8, the sum of the standardized indoor temperature changes in the first period is the largest, the sum of the standardized indoor temperature changes in the third period is the second largest, and the standardized indoor temperature changes in the second period are the largest. The total is the smallest. Accordingly, the first thermal influence of the first air conditioner (20a) corresponding to the first period is the largest, the first thermal influence of the third air conditioner (20c) corresponding to the third period is the second largest, and the first thermal influence of the third air conditioner (20c) corresponding to the third period is the second largest, and the first thermal influence of the first air conditioner (20a) corresponding to the first period is the largest. The first thermal influence of the second air conditioner (20b) corresponding to is the smallest.

As the first thermal influence of the air conditioner 20 increases, the indoor temperature at each point in the target area 10 can change evenly, and the deviation in the indoor temperature at each point can be small. In addition, as the first thermal influence of the air conditioner 20 is smaller, the indoor temperature at each point of the target area 10 may not change evenly, and the deviation of the indoor temperature at each point may be large. Accordingly, the plurality of air conditioners 20 can be driven at the target date by considering the first thermal influence of the plurality of air conditioners 20 .

Meanwhile, there may be multiple test days, and steps S510 to S550 described above may be repeatedly performed on each of the plurality of test days. Therefore, the first thermal influence of the plurality of air conditioners 20 can be calculated for each of the plurality of test days, and the first thermal influence of the plurality of air conditioners 20 can be calculated by averaging the first thermal influence for each of the plurality of test days. The first thermal influence of (20) can be corrected. Accordingly, a more accurate first thermal influence of the plurality of air conditioners 20 can be calculated.

FIG. 9 is a diagram illustrating the overall flowchart of a method for calculating the thermal influence of a plurality of air conditioners 20 according to the second embodiment of the present invention. Here, the thermal influence is a second thermal influence corresponding to the degree to which the overall indoor temperature within the target area 10 is significantly changed.

Hereinafter, the process performed for each step will be described in detail.

In step S910, the management server 70 may control one air conditioner 20 to be operated for each of a plurality of periods.

In step S920, the management server 70 may obtain indoor temperature values measured for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods.

In step S930, the management server 70 may calculate the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 in the target area 10 for each of the plurality of periods.

Meanwhile, steps S910, S920, and S930 are the same as steps S510, S520, and S530 of FIG. 5 described above, so overlapping descriptions will be omitted.

In step S940, the management server 70 may calculate the indoor/outdoor temperature difference for each of the plurality of temperature and humidity sensors 30 in the target area 10 for each of the plurality of periods.

According to an embodiment, the outdoor temperature of the target area 10 may be obtained through the weather server 80 or may be obtained through an external temperature sensor installed outside the target area 10. And, the indoor temperature of the target area 10 may be the indoor temperature at the end of the period, but the present invention is not limited thereto. In addition, since the installation points of the plurality of temperature and humidity sensors 30 installed in the target area 10 are different, the indoor and outdoor temperature differences for each of the plurality of temperature and humidity sensors 30 in a specific period may not be the same.

In step S950, the management server 70 may correct the indoor temperature change amount for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods to the indoor temperature change amount in the case of a preset reference indoor/outdoor temperature difference.

Specifically, according to the research results of the inventor of the present invention, the indoor temperature of the target area 10 changes due to the operation of the air conditioner 20, and at the same time changes due to the temperature difference between the indoor and outdoor temperature of the target area 10. However, the outdoor temperature of the target area 10 changes in real time with the passage of time, and the indoor temperature of the plurality of temperature and humidity sensors 30 may not be the same due to different installation points of the plurality of temperature and humidity sensors 30. , Ultimately, the indoor and outdoor temperature differences for each of the plurality of temperature and humidity sensors 30 in each of the plurality of periods may not be the same. Therefore, a problem arises in which the influence of each of the plurality of air conditioners 20 on the target area 10 cannot be accurately determined due to different indoor and outdoor temperature differences.

Step S950 may be performed to solve this problem. Step S950 may be a step of calculating the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 when each of the plurality of air conditioners 20 is operated independently in an environment with the same indoor and outdoor temperature difference. For this purpose, the management server 70 determines the indoor temperature change amount for each of the plurality of temperature and humidity sensors 30 measured when each of the plurality of air conditioners 20 is operated independently as the preset “reference indoor/outdoor temperature difference”. It can be corrected by the amount of change.

Here, the reference indoor/outdoor temperature difference may be set as any one of the indoor/outdoor temperature differences for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods, but the present invention is not limited thereto.

According to an embodiment, the management server 70 applies the indoor and outdoor temperature differences for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods to preset basic relationship information to determine the plurality of temperature and humidity sensors 30 for each of the plurality of periods. ) The amount of change in indoor temperature can be corrected by the amount of change in indoor temperature in the case of the standard indoor/outdoor temperature difference.

Here, the basic relationship information may be defined as relationship information between the amount of change in indoor temperature in the virtual area according to the temperature difference between the indoor and outdoor temperatures in the virtual area. At this time, the virtual zone may correspond to a zone that integrates all previous zones that the management server 70 has jurisdiction over in advance, and the basic relationship information is based on the driving data of air conditioners installed in all of the previous zones. Can be created in advance.

According to an embodiment, basic relationship information may be expressed as a basic relationship polynomial function equation. In particular, the basic relational polynomial function may be a quadratic function, which can be expressed as Equation 2 below.

Here, ΔT _(oi) is the indoor and outdoor temperature difference in the virtual area, f _b (ΔT _(oi) ) is the amount of change in indoor temperature in the virtual area (i.e., ΔT _i ), and a, b, and c each refer to preset constant terms. do.

Hereinafter, with reference to FIG. 10, the operation of the management server 70 to correct the indoor temperature change amount A to the indoor temperature change amount A' in the case of the reference indoor/outdoor temperature difference will be described in detail. The content described in FIG. 10 can be applied to the correction process of the amount of change in indoor temperature for each of the plurality of temperature and humidity sensors 30 for each of the plurality of periods.

FIG. 10 is a diagram illustrating the concept of the operation of the management server 70 that corrects a specific indoor temperature change amount to the indoor temperature change amount in the case of a reference indoor/outdoor temperature difference, according to an embodiment of the present invention.

First, the management server 70 specifies the indoor temperature change amount A(△T _i,A ) according to the indoor/outdoor temperature difference A(△T ( _oi),A ) (process ① in FIG. 10). This can be performed based on steps S930 and S940 described above.

Next, the management server 70 substitutes the indoor/outdoor temperature difference A(△T _(oi),A ) into the basic relational polynomial function equation (f _b (△T _(oi) )) to determine the basic indoor temperature change amount A(△T _{i, b,A} ) is calculated (process ② of Figure 10).

Continuing, the management server 70 _uses the basic relational polynomial function equation ( _{f b} (△ T _(oi) )) is corrected to calculate the corrected basic relational polynomial function equation (f _C (△T _(oi) )) (process ③ in Figure 10).

That is, processes ①, ②, and ③ of FIG. 10 may be processes for correcting the basic relational polynomial function equation (f _b (△T _(oi) )) based on the indoor/outdoor temperature difference A and the indoor temperature change amount A.

Meanwhile, according to the research results of the inventor of the present invention, when a change in the regional environment such as a change in the desired temperature of the air conditioner occurs, the basic relational polynomial function equation (f _b (△T _(oi) )) changes the constant term but the variable term. has fixed characteristics. Considering these characteristics, the basic relational polynomial function (f _b (△T _(oi) )) and the corrected basic relational polynomial function (f _C (△T _(oi) )) have the same variable terms and do not change the constant term. have a relationship At this time, the constant term can be changed based on the difference between the indoor temperature change amount A(△T _i,A ) and the basic indoor temperature change amount A(△T _i,b,A ). In other words, the corrected basic relational polynomial function (f _C (△T _(oi) )) is a polynomial function in which the basic relational polynomial function (f _b (△T _(oi) )) is moved upward or downward by the above-mentioned difference value. You can.

Finally, the management server 70 calculates _the indoor temperature change amount _A (△ _{T i ,A} ) is corrected by the indoor temperature change amount A'(△T _i,A' ) in the case of the reference indoor/outdoor temperature difference (△T _(oi),R ) (process ④ in Figure 10).

In other words, the management server 70 substitutes the reference indoor/outdoor temperature difference (△T _{(oi) ,R} ) into the corrected basic relational polynomial function (f _C (△T (oi))), and the corrected basic indoor temperature change amount A' can be calculated. At this time, when the corrected basic indoor temperature change amount A' is the correction value of the indoor temperature change amount A(△T _i,A ), that is, the standard indoor/outdoor temperature difference (△T _(oi),R ), the indoor temperature change amount A'(△ It may be T _i,A' ).

FIG. 11 shows the amount of indoor temperature change for each corrected temperature and humidity sensor 30 in the situation of FIG. 7 .

Referring to FIG. 11, assuming that the indoor and outdoor temperature differences are the same, the indoor temperature change amount of the three temperature and humidity sensors 30 for the three air conditioners 20a, 20b, and 20c is expressed.

Referring again to FIG. 9, in step S960, the management server 70 operates the plurality of air conditioners 20 based on the amount of indoor temperature change for each of the plurality of corrected temperature and humidity sensors 30 for each of the plurality of periods. The second thermal influence can be calculated.

As described above, the second thermal influence of the air conditioner 20 may correspond to the degree of changing the overall indoor temperature of the target area 10. In other words, the second thermal influence of the air conditioner 20 may correspond to the amount of change in the overall indoor temperature of the target area 10 when the air conditioner 20 is driven.

As the second thermal influence of the air conditioner 20 increases, the amount of change in the overall indoor temperature of the target area 10 increases, and the overall indoor temperature of the target area 10 may increase rapidly. In addition, as the second thermal influence of the air conditioner 20 decreases, the amount of change in the overall indoor temperature of the target area 10 decreases, and the overall indoor temperature of the target area 10 may increase slowly.

According to the embodiment, the management server 70 calculates the total or average value of the indoor temperature changes corrected for each of the plurality of temperature and humidity sensors 30 in the x-th period among the plurality of periods to the air conditioner 20 corresponding to the x-th period. It can be calculated as the second thermal influence.

Hereinafter, for convenience of explanation, the total amount of indoor temperature change corrected for each of the plurality of temperature and humidity sensors 30 is assumed to be the second thermal influence of the air conditioner 20.

As an example, referring to Figure 11, the total amount of indoor temperature change corrected in the first period is the largest, the total amount of indoor temperature change corrected in the third period is the second largest, and the total amount of indoor temperature change corrected in the third period is The total is the smallest. Accordingly, the second thermal influence of the first air conditioner (20a) corresponding to the first period is the largest, the second thermal influence of the third air conditioner (20c) corresponding to the third period is the second largest, and the second thermal influence of the third air conditioner (20c) corresponding to the third period is the largest. The second thermal influence of the second air conditioner (20b) corresponding to is the smallest.

The greater the second thermal influence of the air conditioner 20, the greater or faster the overall indoor temperature of the target area 10 may change, and the smaller the second thermal influence of the air conditioner 20, the greater or faster the change in the overall indoor temperature of the target area 10. Indoor temperature may change little or slowly. Accordingly, the plurality of air conditioners 20 can be driven on the target day by considering the second thermal influence of the plurality of air conditioners 20 .

Meanwhile, there may be multiple test days, and steps S910 to S960 described above may be repeatedly performed on each of the plurality of test days. Therefore, the second thermal influence of the plurality of air conditioners 20 can be calculated for each of the plurality of test days, and the second thermal influence of the plurality of air conditioners 20 can be calculated by averaging the second thermal influence for each of the plurality of test days. The second thermal influence of (20) can be corrected. Accordingly, a more accurate second thermal influence of the plurality of air conditioners 20 can be calculated.

Meanwhile, the content described above may be performed in the control module 40 rather than the management server 70. In this case, the control module 40 includes a high-performance processor-based control unit and may further include the second short-range communication module and the infrared communication module described above. The control module 40 may acquire the indoor temperature value of the target area 10 measured by the temperature and humidity sensor 30 through the gateway 50. Additionally, the temperature and humidity sensor 30 and the control module 40 may be built into the air conditioner 20. In this case, the control module 40 may directly obtain the indoor temperature value from the temperature and humidity sensor 30. Since the operations performed by the control module 40 are similar to the above description, detailed description will be omitted.

Additionally, embodiments of the present invention may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, etc., singly or in combination. Program instructions recorded on the medium may be specially designed and constructed for the present invention or may be known and usable by those skilled in the art of computer software.
