Description

Embodiments of the present invention relate to air conditioning control systems, air conditioning control methods and programs.

When an air conditioner is used in a space such as an office or a residence, the temperature or the like may be set with priority given to efficient use of energy (energy saving). In such a case, it is conceivable that the user will be in an unpleasant situation of being hot or cold, and the possibility that the user will tolerate the set value will be low. On the other hand, if the user sets the temperature of the air conditioner to an arbitrary value, sufficient energy saving may not be achieved.

In recent years, a technique has been proposed in which the structure data and room temperature data of a building are acquired, the space inside the building is divided, the temperature change of each space is estimated, and the air conditioning control amount is calculated based on the estimation result to control the air conditioning. There is. In addition, the heat load in the building is estimated using the amount of power generated by the photovoltaic power generation device, the power consumption of home appliances, its location information, the occupancy information of the occupants and their location information, etc., and air conditioning is performed based on the estimation results. Control techniques have been proposed. In addition, a technique has been proposed in which feedback on the room temperature from the occupants is aggregated and reflected in the air conditioning control.
However, in these methods, the target temperature value is controlled toward one preset target temperature value in the system, or the target temperature value is controlled by one type of pattern with respect to the aggregated feedback value. However, it was not possible to follow the change in the thermal sensation of the occupants, and it was not always possible to say that the occupants were comfortable.

(First Embodiment)
FIG. 1 is a functional block diagram showing the overall configuration of the air conditioning control system 100 of the first embodiment. The air conditioning control system 100 controls indoor air conditioning based on the collected indoor and outdoor heat load conditions. The air conditioning control system 100 acquires information (for example, outside air temperature) representing the indoor and outdoor heat load status from, for example, a building energy management system (hereinafter referred to as “BEMS”) 200.

The air conditioning control system 100 is realized by, for example, a device including a CPU (Central Processing Unit) and a RAM (Random Access Memory). By executing the air conditioning control program, the air conditioning control system 100 functions as a scene determination unit 101, a cycle determination unit 102, an instruction condition determination unit 103, an instruction value determination unit 104, an instruction unit 105, and a set temperature history value management unit 106. To do. The air conditioning control system 100 may be built in an information processing device such as a server or a personal computer, or may be included in the BEMS 200. Further, the air conditioning control system 100 may be built on the cloud computing system. The air conditioning control system 100 may be configured on any other system.

The scene determination unit 101 determines the usage scene of the air conditioning control area at a predetermined timing based on the sensing information. The sensing information is information on the usage status of the air conditioning control area whose temperature is controlled by the air conditioner. The sensing information is, for example, the amount of power used and the amount of heat generation fluctuation. Sensing information is an aspect of indoor environment information. When deciding the usage scene, the scene determination unit 101 acquires the average value of the sensing information collected retroactively for a predetermined time. The predetermined time may be 1 hour, 30 minutes, or 2 hours. The predetermined time may be any time. The power consumption is the power consumption of the equipment arranged in the air conditioning control area. The scene determination unit 101 acquires the amount of activity fluctuation from the calorific value estimation unit 202. The amount of activity fluctuation is determined based on the number of people in the room or the room temperature in the air conditioning control area. The predetermined timing may be, for example, once a day or twice a week. The predetermined timing may be any timing. The air conditioning control area is an area where the air conditioner 400 controls the temperature. The usage scene shows how to use the air conditioning control area such as general desk work, window and reception. The usage scene is information that determines the cycle for accepting the intention to review the set temperature of the air conditioning control area.

The cycle determination unit 102 determines the cycle for accepting the intention to review the set temperature of the air conditioner 400 based on the usage scene determined by the scene determination unit 101 and the number of people information at the current time. The cycle determination unit 102 acquires information on the number of people in the air conditioning control area from the number determination unit 203. The intention to review the set temperature is an evaluation of the environment of the air conditioning control area collected from humans in the air conditioning control area. The time at the beginning and end of the cycle for accepting the intention to review the set temperature is called the review time. The review time is determined by the cycle determination unit 102 based on the determined cycle. At each review time, the next review time is determined based on the cycle determined by the cycle determination unit 102. The review time is the time for setting the set temperature review intention from the feedback unit 300 to the initial value, and the time between the two consecutive review times is the time when the set temperature review intention from the feedback unit 300 is accepted. is there. The intention to review the set temperature from the feedback unit 300 is given as a feedback evaluation value. The review time determined by the cycle determination unit 102 is set in the instruction condition determination unit 103 and the instruction value determination unit 104. The initial setting value of the review time may be a numerical value preset in the system, or may be configured so that the system administrator can arbitrarily change it.

The instruction condition determination unit 103 determines the first temperature control condition based on the outdoor environment information acquired from the outdoor environment detection unit 204 at each review time. The outdoor environment information is information about the environment outside the air conditioning control area. The outdoor environment information is, for example, the outside air temperature and the amount of solar radiation. The instruction condition determination unit 103 acquires outdoor environment information from the outdoor environment detection unit 204. The first temperature control condition defines a specific code and numerical value regarding the direction and width for changing the set temperature of the air conditioner 400. The instruction condition determination unit 103 is an aspect of the control condition determination unit. The first temperature control condition is one aspect of the temperature control condition.

The indicated value determination unit 104 determines the feedback evaluation threshold value based on the usage scene determined by the scene determination unit 101. The feedback evaluation threshold value is used to determine whether or not the instruction value determination unit 104 outputs a temperature control instruction. For example, when the feedback evaluation value received from the feedback unit 300 exceeds the feedback evaluation threshold value, the instruction value determination unit 104 outputs a temperature control instruction to the instruction unit 105. As for the temperature control instruction, the temperature control instruction is output only once at the interval between the review time and the review time. The temperature control instruction includes a set temperature value determined based on the current set temperature value acquired from the set temperature history value management unit 106 and the first temperature control condition received from the instruction condition determination unit 103. .. Specifically, the new set temperature value is determined by adding the first temperature control condition received from the instruction condition determination unit 103 to the current set temperature value acquired from the set temperature history value management unit 106. The feedback evaluation threshold is one aspect of the first threshold for the intention to review the set temperature.

The indicated value determination unit 104 updates the feedback evaluation value received from the feedback unit 300 at the review time determined by the cycle determination unit 102 and sets it as an initial value. For example, the initial value of the feedback evaluation value may be 0, or may be a numerical value preset in the system. For the time between the two consecutive review times, the feedback evaluation value received from the feedback unit 300 is integrated as the set temperature review intention. The initial value of the feedback evaluation value may be configured so that the system administrator can arbitrarily change it.

The indicated value determining unit 104 gives a reset instruction to the indicated unit 105 at a predetermined timing. The reset instruction is an instruction to change the set temperature of the air conditioner 400 to the initial set temperature. The predetermined timing may be twice a week (for example, Wednesday and Sunday), or may be any timing. The predetermined timing may be defined according to the usage pattern of the air conditioning control area. The indicated value determining unit 104 determines the initial set temperature of the air conditioner 400 instructed by the reset instruction. As the initial set temperature, a predetermined set temperature may be used, or the indicated value determination unit 104 acquires the set temperature from the set temperature history value management unit 106 to the time retroactive to a predetermined time, and the current time. The set temperature may be the average value or the minimum value of the temperature control instructions output from the above in a predetermined period. The predetermined period may be one day, one week, or the time from the time when the reset instruction was last issued to the current time.

The instruction unit 105 sets the set temperature in the air conditioner 400 based on the temperature control instruction or the reset instruction received from the instruction value determination unit 104. The instruction unit 105 records the set temperature registered in the air conditioner 400 based on the temperature control instruction in the set temperature history value management unit 106.

The set temperature history value management unit 106 may be configured by using a storage device such as a magnetic hard disk device or a semiconductor storage device, or may be configured by using a relay device capable of information communication with the BEMS 200 or an external storage device. Alternatively, it may be configured by a program reference file. The set temperature history value management unit 106 stores the set temperature set in the air conditioner 400 by the instruction unit 105 in itself or an external storage device or a file, and acquires the set temperature history value stored in itself or the external storage device. Is output to the indicated value determination unit 104.

The BEMS 200 is executed by a device including, for example, a CPU and RAM. By executing the building management program, the BEMS 200 functions as an electric energy detection unit 201, a calorific value estimation unit 202, a number of people determination unit 203, and an outdoor environment detection unit 204. The BEMS 200 may be built in an information processing device such as a server or a personal computer. The BEMS 200 may be built on a cloud computing system. The BEMS 200 may be configured on any other system.

The electric energy detection unit 201 obtains the electric energy of the equipment arranged in the air conditioning control area. The electric energy detection unit 201 outputs the electric energy used to the scene determination unit 101. Examples of the device include an information processing device such as a personal computer or a server, or an office processing device such as an MFP multifunction device or a shredder. The power consumption may be aggregated from software built into the device, or may be obtained from a watt-hour meter that measures the power consumption of the device.

The calorific value estimation unit 202 obtains the calorific value fluctuation amount based on the sensing information such as the number of people information and the room temperature information. The calorific value estimation unit 202 outputs the calorific value fluctuation amount to the scene determination unit 101. The number of people information is information obtained based on the number of people existing in the air conditioning control area. As the number of people information, for example, the number of people determined by the behavior estimation engine that estimates the amount of activity of occupants based on the amount of detection signals of the infrared motion sensor is used. As the number of people information, the number of people obtained from a single sensor such as an image motion sensor may be used. As the number of people information, the number of people managed by the admission management system or the number of people counting device may be used. Room temperature information is information obtained based on the room temperature in the air conditioning control area. As the room temperature information, the amount of change in room temperature that records the change over time in room temperature may be used. The amount of heat generation fluctuation may be determined, for example, from the heat load for the number of people. A heat load per person may be prepared for each room temperature, and the amount of heat generation fluctuation in the air conditioning control area may be determined by multiplying the acquired number of people. In addition, the heat load per person may be further divided according to the season such as summer, winter, and the middle period, and the heat load per person may be further divided for each time zone such as morning, noon, and afternoon. It may be divided into cases. The amount of heat generation fluctuation may be determined, for example, from the amount of change in room temperature during a predetermined period. The predetermined period is, for example, 30 minutes or 2 hours. For example, when the absolute value of the room temperature change amount exceeds 1 ° C. within 30 minutes, which is a predetermined period, the heat generation fluctuation amount is largely defined. For example, when the absolute value of the room temperature change amount is less than 2 ° C. within 2 hours, which is a predetermined period, the heat generation fluctuation amount is defined as small. The heat load per person for each room temperature, a specific numerical value for a predetermined period, and a threshold value for determining the magnitude of the change in room temperature may be configured to be arbitrarily changed by the system administrator.

The number of people determination unit 203 determines the number of people in the air conditioning control area based on the number of people information. The number of people determination unit 203 may be acquired from, for example, a behavior estimation engine that estimates the number of occupants based on the amount of detection signals of the infrared motion sensor. The number of people determination unit 203 may use the number of people information obtained from a single sensor such as an image motion sensor. The number of people determination unit 203 may use the number of people managed by the admission management system or the number of people counting device. The number of people determination unit 203 may use the instantaneous value at the time of program execution as the number of people information, or may use the average value for a certain period of time retroactively from the time of program execution. When the average value is used, the time interval for calculating the average value may be configured so that the system administrator can arbitrarily change it.

The outdoor environment detection unit 204 collects outdoor environment information. The outdoor environment detection unit 204 outputs the outdoor environment information to the instruction condition determination unit 103. In the first embodiment, the outdoor air temperature and the amount of solar radiation are used as the outdoor environment information, but any other information may be used. As the outdoor environment information, for example, PV (Photovoltaics) power generation amount or outdoor illuminance information may be used instead of the amount of solar radiation. For the outdoor environment information, for example, the outside air humidity may be used instead of the outside air temperature. As the outdoor environment information, the data aggregated from the environment sensors installed in the same building may be used, or the data acquired from the environment sensors installed in the area close to the air conditioning control area or the Meteorological Agency or an external database. It may be used.

The feedback unit 300 receives the opinions of the occupants regarding the temperature in the air conditioning control area. The opinions of the occupants are quantified as feedback evaluation values and output to the indicated value determination unit 104. The feedback unit 300 is an information processing device such as a personal computer. In the case of a place where specific people gather, such as an office, the feedback unit 300 is arranged in an employee seat in, for example, an air conditioning control area. The feedback unit 300 is arranged at the entrance / exit of a facility in the case of a place where unspecified people gather, such as a department store or a station. The feedback unit 300 may be a program executed in an information processing device such as a smartphone or an information processing device. The feedback unit 300 may be configured so as not to receive opinions from the same person a plurality of times within a certain period of time.

The case where the feedback unit 300 is a device managed by the system administrator and the identity of the sender of the opinion input to the feedback unit 300 cannot be specified or limited will be described. When the feedback unit 300 receives an opinion, the feedback unit 300 does not have to accept the next input for a predetermined time. The predetermined time is, for example, 3 seconds. The predetermined time may be configured so that the system administrator can arbitrarily change it. The device managed by the system administrator is a button, digital signage, tablet or personal computer installed in a public place such as a department store. The indicated value determining unit 104 may be configured to receive an opinion instead of the feedback unit 300.

A case where the identity of the sender of the opinion input to the feedback unit 300 can be specified or limited will be described. The feedback unit 300 may receive opinions from a specific person not only once but also a plurality of times within a predetermined period. For example, the feedback unit 300 may receive opinions from the same person up to twice within one hour. Further, when the feedback unit 300 accepts an opinion, it is not necessary to accept an input from the same person for a predetermined time. The predetermined time is, for example, 15 minutes. The predetermined time interval and the predetermined time may be configured so that the system administrator can arbitrarily change them. The specific person is, for example, a person identified by a login account for a website or application that functions as a feedback unit 300, a person who uses an assigned dedicated booth, and the like. The indicated value determining unit 104 may be configured to receive an opinion instead of the feedback unit 300.

The air conditioner 400 controls the temperature in the air conditioning control area to a set temperature. The set temperature of the air conditioner 400 is changed to the set temperature set by the indicator 105. The air conditioner 400 may have a plurality of air conditioning control areas. When the air conditioner 400 has a plurality of air conditioning control areas, the air conditioner 400 may have a set temperature for each air conditioning control area. The air conditioner 400 may control an environment other than temperature (for example, humidity).

FIG. 2 is a diagram showing a specific example of a parameter table for determining a usage scene of the first embodiment. The usage scenes are classified into four usage scenes according to the high and low power consumption and the high and low calorific value fluctuation. For example, when the amount of power used is high and the amount of heat generation fluctuation is low, the scene determination unit 101 determines the usage scene as A (for example, general desk work in a normal office or telephone reception work in a call center). Similarly, when the amount of power used is low and the amount of heat generation fluctuation is low, the scene determination unit 101 determines that the usage scene is B (for example, during lunch break or during a lecture in a conference room). Similarly, when the amount of electricity used is high and the amount of heat generation fluctuation is high, the scene determination unit 101 determines the usage scene as C (for example, active office work at a financial exchange, a television broadcasting station, or a newspaper company). To do. Similarly, when the amount of power used is low and the amount of heat generation fluctuation is low, the scene determination unit 101 determines the usage scene as D (for example, work in a reception desk or a mail room). The high and low threshold values for the amount of power consumption and the amount of heat generation fluctuation may be any numerical value defined by a specific numerical value, and may be configured to be arbitrarily changed by the system administrator. The threshold value may be three or more steps instead of two steps of high and low. A plurality of usage scenes may be determined in one day. The parameter table for determining the usage scene may be defined for each building or for each purpose of the building.

FIG. 3 is a diagram showing a specific example of a parameter table for determining a usage scene of the first embodiment. For example, when the amount of power used is 15 kWh or more and the amount of heat generation fluctuation is less than 1 kW, the scene determination unit 101 determines the usage scene as A (for example, general desk work in a normal office or telephone reception work in a call center). Similarly, when the amount of power used is less than 15 kWh and the amount of heat generation fluctuation is less than 1 kW, the scene determination unit 101 determines the usage scene as B (for example, during lunch break or listening to a lecture in a conference room). As the power consumption, the power consumption for a certain period of time retroactive from the time when the usage scene is determined may be used. As for the calorific value fluctuation amount, the average value of the calorific value fluctuation amount for a certain period of time retroactive from the time when the usage scene is determined may be used. Alternatively, the calorific value fluctuation amount at the time of determining the usage scene may be used.

FIG. 4 is a diagram showing a specific example of a cycle for determining the review time of the first embodiment. The cycle is classified into 8 patterns according to the usage scene and the amount of information on the number of people. For example, when the usage scene is A and the number of people information is large, the cycle determination unit 102 determines that the cycle is “short”. “Short” means, for example, that the period of the review time interval is 30 minutes. Similarly, when the usage scene is A and the number of people information is small, the cycle determination unit 102 determines that the cycle is “long”. “Long” means, for example, that the period of the review time interval is 2 hours. Here, the specific numerical values of "short" and "long" may be any defined numerical values, and may be configured so that the system administrator can arbitrarily change them. The threshold value of the number of people information may be three or more levels instead of two levels, or may differ depending on the day of the week, business days, regular holidays, seasons, and the like.

FIG. 5 is a diagram showing a specific example of a cycle for determining the review time of the first embodiment. For example, when the usage scene is A and the number of people information is 10 or more, the cycle determination unit 102 determines that the cycle, which is the interval of the review time, is 30 minutes. Similarly, when the usage scene is A and the number of people information is less than 10, the cycle determination unit 102 determines that the cycle, which is the interval of the review time, is 2 hours. The cycle pattern for determining the review time may be defined for each building or for each purpose of the building.

FIG. 6 is a diagram showing a specific example of the first temperature control condition of the first embodiment. The first temperature control condition in the first embodiment is classified into 6 patterns according to the outside air temperature and the amount of solar radiation. For example, when the outside air temperature is high and the amount of solar radiation is high, the instruction condition determination unit 103 determines that the temperature control instruction condition is “large”. “Large” means, for example, that the set temperature of the air conditioner 400 is controlled to be lowered by 1.5 ° C. in the case of operating the cooling control system. Similarly, when the outside air temperature is high and the amount of solar radiation is low, the instruction condition determination unit 103 determines that the temperature control instruction condition is “medium”. “Medium” indicates, for example, that the set temperature of the air conditioner 400 is controlled to be lowered by 1 ° C. in the case of operating the cooling control system. Here, the specific numerical values of "large", "medium", and "small" may be any defined numerical values, and all six patterns may have different values. In addition, the numerical value may be configured so that the system administrator can arbitrarily change it. The threshold value of the amount of solar radiation may be three or more levels instead of two levels of high and low, and the threshold value of the outside air temperature may be four or more levels instead of three levels.

FIG. 7 is a diagram showing a specific example of the first temperature control condition of the first embodiment. For example, when the outside air temperature is 30 ° C. or higher and the amount of solar radiation is 2 MJ / m2 or higher, the instruction condition determination unit 103 instructs the control to lower the set temperature of the air conditioner 400 by 1.5 ° C. when operating the cooling control system. Output to the value determination unit 104. Similarly, when the outside air temperature is 30 ° C. or higher and the amount of solar radiation is less than 2 MJ / m2, the instruction condition determination unit 103 controls to lower the set temperature of the air conditioner 400 by 1 ° C. in the case of operating the cooling control system. Output to the determination unit 104. It is desirable that the first temperature control condition is defined for each of cooling control and heating control. It may also be defined according to the location of the air conditioning control area. When defined for each air conditioning control area, the air conditioning control area with many windows and the control area adjacent to the doorway are easily affected by outdoor environmental information, and the air conditioning control area without windows and the control area away from the doorway. Can absorb the differences in each air-conditioning control area, such as being less affected by outdoor environment information, and control the temperature.

FIG. 8 is a diagram showing a specific example of the feedback evaluation threshold value of the first embodiment. The feedback evaluation threshold is classified according to the usage scene. In the first embodiment, it is classified into four usage thresholds according to four usage scenes. For example, when the usage scene is A, the indicated value determination unit 104 determines that the feedback evaluation threshold value is “low”. When "low" is, for example, when the feedback evaluation value received from the feedback unit 300 is larger than the numerical value specifically determined by "low", the indicated value determination unit 104 has acquired the current set temperature history value management unit 106. The set temperature value determined based on the set temperature and the first temperature control condition received from the instruction condition determination unit 103 is output to the instruction unit 105. Similarly, when the usage scene is C, the indicated value determination unit 104 determines that the feedback evaluation threshold value is “medium”. In this case, when the feedback evaluation value received from the feedback unit 300 is larger than the numerical value specifically determined by "medium", the indicated value determination unit 104 and the current set temperature acquired from the set temperature history value management unit 106 The set temperature value determined based on the first temperature control condition received from the instruction condition determination unit 103 is output to the instruction unit 105. Similarly, here, the specific numbers "low" and "medium" may be any defined number and may be configured to be arbitrarily changed by the system administrator. The feedback threshold may be 3 or 4 levels instead of 2 levels, and may differ depending on the day of the week, business day, regular holiday, season, and the like.

FIG. 9 is a diagram showing a specific example of the feedback evaluation threshold value of the first embodiment. For example, when the usage scene is A, the indicated value determination unit 104 sets the feedback evaluation threshold value to 25. When the feedback evaluation value received from the feedback unit 300 is larger than 25, the instruction value determination unit 104 receives the current set temperature acquired from the set temperature history value management unit 106 and the first temperature control received from the instruction condition determination unit 103. The set temperature value determined based on the conditions is output to the indicator 105. Similarly, when the usage scene is C, the indicated value determination unit 104 sets the feedback evaluation threshold value to 50. In this case, when the feedback evaluation value received from the feedback unit 300 is larger than 50, the instruction value determination unit 104 receives the current set temperature acquired from the set temperature history value management unit 106 and the instruction condition determination unit 103. (1) The set temperature value determined based on the temperature control condition is output to the indicator 105.

FIG. 10 is a diagram showing a specific example of an image displayed to the user in the feedback unit 300 of the first embodiment. The feedback unit 300 of the first embodiment receives the opinions of the occupants in, for example, three patterns of characters and colors of "hot", "just right", and "cold". Feedback evaluation values correspond to the opinions of the three patterns of occupants. The area 500 is a specific example of an image displayed to the user in the feedback unit 300. The user inputs an opinion by selecting the characters and colors or icons of the areas 501 to 503 included in the area 500. For example, when region 501 is selected, a "hot" opinion is entered and the feedback evaluation value is added as "+1". When the area 502 is selected, a "just right" opinion is input and the feedback evaluation value is added as "0". When region 503 is selected, a "cold" opinion is entered and the feedback evaluation value is added as "-1". The specific amount to be added once each area is selected is defined numerically and added in the plus or minus direction. In addition, the number of times all areas are selected is separately counted as the total number of receptions so that the effect of "just right" is not diminished, and the result of the addition is averaged by the total number of opinions received as the feedback evaluation value. It may be defined in.

FIG. 11 is a diagram showing a specific example when the cooling control system operation of the first embodiment is operated in a public place for one day. When the cooling control system is operated in a public place, the scene determination is performed once a day. The scene determination unit 101 determines the usage scene at 9 o'clock every day. The determined usage scene is used until the next usage scene determination time. The scene determination unit 101 determines the usage scene based on the average value of the sensing information collected retroactively for a predetermined time. The indicated value determination unit 104 determines the feedback evaluation threshold value based on the determined usage scene. Further, in the example of FIG. 11, 9 o'clock is the review time. Therefore, the cycle determination unit 102 determines the cycle for determining the next review time based on the number of people information received from the number determination unit 203. In the example of FIG. 11, it is determined that the cycle from 9 o'clock to the next review time is all 30 minutes, and the review time continues in a 30-minute cycle of 9:30, 10 o'clock, and so on. Further, in the example of FIG. 11, the cycle from 17:30 to the next review time changes to 2 hours. Therefore, the review time continues in a two-hour cycle of 19:30, 21:30, and so on. The review time and the usage scene determination time do not necessarily have to be the same time, but it is desirable to determine the cycle, which is the interval until the next review time, as the usage scene is updated.

In the cooling control system, the feedback evaluation value is counted as a positive direction (+1) when it is "hot", a negative direction (-1) when it is "cold", and 0 when it is "just right". In FIG. 11, the feedback evaluation value does not exceed the feedback threshold between 9 o'clock and 9:30 and 9:30 and 10 o'clock. Therefore, the feedback evaluation value is set to the initial value of 0 at 9:30 and 10:00, which are the review times. On the other hand, between 10:00 and 10:30, the feedback evaluation value exceeds the feedback evaluation threshold. When the feedback evaluation threshold is exceeded, the indicated value determination unit 104 determines a new set temperature value from the first temperature control condition and the current set temperature value, and outputs a temperature control instruction including the new set temperature value to the indicator unit 105. To do. Upon receiving the temperature control instruction, the instruction unit 105 sets the set temperature of the air conditioner 400 to a new set temperature and records it in the set temperature history value management unit 106.

FIG. 12 is a diagram showing a specific example of operating the air conditioning control system of the first embodiment in a public place for one week. In the example shown in FIG. 12, the scene determination unit 101 determines the usage scene at 9 o'clock every day. The determined usage scene is used until the next usage scene is determined, that is, until 9:00 the next day. In addition, the instruction value determination unit 104 gives a reset instruction to the instruction unit 105 at 23:00 every day. Based on the reset instruction, the instruction unit 105 changes the set temperature of the air conditioner 400 to the initial set temperature. The time and day of the week when the usage scene is determined and the reset instruction is given may be configured so that the system administrator can arbitrarily change it. There may be a modified operation pattern by registering events such as business days, regular holidays, and holidays as well as days of the week. The usage scene of the air conditioning control system and the determination time of the reset instruction may be set differently depending on the place where the air conditioning control system is installed. For example, a scene determination time may be set frequently in a place where the usage scene changes frequently, such as an exhibition hall or a meeting place, and a scene determination time may be set in a place where the usage scene changes little, such as a showroom or reception. May be set low.

FIG. 13 is a diagram showing a specific example when the cooling control system of the first embodiment is operated in an office for one day. When the cooling control system is operated in the office, the scene determination is performed twice a day. The scene determination unit 101 determines the usage scene at 9:00 and 13:30 every day. The determined usage scene is used until the next usage scene determination time. The method of determining the usage scene is the same as the example shown in FIG. The indicated value determination unit 104 determines the feedback evaluation threshold value based on the determined usage scene. Further, in the example of FIG. 13, 9:00 and 13:30 are also review times. Therefore, the cycle determination unit 102 determines the cycle for determining the next review time based on the number of people information received from the number determination unit 203 at 9:00 and 13:30. Similar to the example of FIG. 11, in the example of FIG. 13, it is determined that the cycle from 9 o'clock to the next review time is all 30 minutes, and the cycle is 9:30, 10 o'clock, ... The review time continues. The review time will be determined again at 13:30, but the review time will continue at 30-minute intervals thereafter. Further, in the example of FIG. 13, the cycle from 17:30 to the next review time changes to 2 hours. Therefore, the review time continues in a two-hour cycle of 19:30, 21:30, and so on. At the review time, the feedback evaluation value is set to 0, which is the initial value. The review time and the usage scene determination time do not necessarily have to be the same time, but it is desirable to determine the cycle, which is the interval until the next review time, as the usage scene is updated.

FIG. 14 is a diagram showing a specific example of operating the air conditioning control system of the first embodiment in an office for one week. In the example shown in FIG. 14, the scene determination unit 101 determines the usage scene at 9:00 and 13:30 every day. However, on Saturdays and Sundays, the usage scene will be decided only at 9:00. The determined usage scene is used until the next usage scene is determined, that is, until 13:30 on the same day or 9:00 on the next day. The instruction value determination unit 104 gives a reset instruction to the instruction unit 105 every Wednesday and Sunday at 23:00. Based on the reset instruction, the instruction unit 105 changes the set temperature of the air conditioner 400 to the initial set temperature. The time and day of the week when the usage scene is determined and the reset instruction is given may be configured so that the system administrator can arbitrarily change it. There may be a modified operation pattern by registering events such as business days, regular holidays, and holidays as well as days of the week. The usage scene of the air conditioning control system and the determination time of the reset instruction may be set differently depending on the place where the air conditioning control system is introduced. For example, a decision time may be set frequently in a place where the usage scene changes frequently, such as an exhibition hall or a meeting place, and a decision time may be set less in a place where the usage scene changes little, such as a showroom or reception. You may.

FIG. 15 is a flowchart showing a processing flow when determining a usage scene of the first embodiment. The instruction value determination unit 104 of the air conditioning control system 100 determines whether or not the current time is the time for issuing the reset instruction (step S101).

FIG. 16 is a flowchart showing a flow of processing for determining the review time and determining the temperature control condition of the first embodiment. The instruction condition determination unit 103 of the air conditioning control system 100 acquires outdoor environment information from the outdoor environment detection unit 204 (step S201). The instruction condition determination unit 103 determines the first temperature control condition based on the outdoor environment information (step S202).

The cycle determination unit 102 acquires the number of people information from the number of people determination unit 203 (step S204). The cycle determination unit 102 determines the review cycle based on the usage scene and the number of people information (step S205). Based on the determined cycle, the cycle determination unit 102 determines the next review time (step S206).

FIG. 17 is a flowchart showing the flow of the temperature setting process for the air conditioner 400 of the first embodiment. The indicated value determining unit 104 acquires a feedback evaluation value from the feedback unit 300 (step S301). The instruction value determination unit 104 determines whether or not the feedback evaluation value is larger than the feedback evaluation threshold value and the temperature control instruction is not executed from the previous review time to the current time (step S302). When the temperature control instruction is larger than the feedback evaluation threshold value and the temperature control instruction is not executed from the previous review time to the current time (step S302: Yes), steps S303 to S308 are executed. If the temperature control instruction is executed from the feedback evaluation threshold value or less, or from the previous review time to the current time (step S302: No), the transition to step S309 occurs.

The indicated value determining unit 104 receives the first temperature control condition from the indicated condition determining unit 103 (step S303). The indicated value determination unit 104 receives the current set temperature value from the set temperature history value management unit 106 (step S304). The indicated value determining unit 104 adds the first temperature control condition from the current set temperature value and determines a new set temperature value (step S305). The indicated value determining unit 104 outputs a temperature control instruction including a new set temperature value to the indicated unit 105 (step S306). The indicator 105 sets the set temperature in the air conditioner 400 based on the temperature control instruction (step S307). The instruction unit 105 records the temperature set in the air conditioner 400 based on the temperature control instruction in the set temperature history value management unit 106 (step S308). The air conditioning control system 100 waits until the next operation timing (step S309).

FIG. 18 is a flowchart showing the flow of processing of the reset instruction according to the first embodiment. The indicated value determination unit 104 acquires all the set temperatures from the set temperature history value management unit 106 by tracing back a predetermined period from the current time (step S401). The indicated value determination unit 104 determines the set temperature indicated by the reset instruction based on the set temperature acquired from the set temperature history value management unit 106 (step S402).

In the air conditioning control system 100 configured in this way, the indicated value determining unit 104 can perform temperature control triggered by the feedback evaluation value collected from the occupants based on the information acquired from the BEMS 200. Therefore, it is possible to maintain and provide a temperature that follows the experience of the occupant. Therefore, it is possible to provide a more comfortable environment for the occupants. Further, since the energy tends to increase if the temperature that follows the occupants is continuously provided, the instruction value determination unit 104 issues a reset instruction at a predetermined timing. An energy saving effect can be obtained by resetting the set temperature according to the reset instruction.

(Modification example)
FIG. 19 is a diagram showing a first modification example of the image displayed on the feedback unit 300 of the first embodiment. The feedback unit 300 of the first embodiment accepts three types of opinions of "hot", "just right" or "cold" and three patterns of icons divided into three colors of red, green and blue. Feedback evaluation values are defined to correspond to each of the three types of patterns. The area 500a is a specific example of an image displayed to the user from the feedback unit 300. The user can input an opinion by selecting the icons of the areas 501a to 503a included in the area 500a. For example, when the icon of the area 501a is selected, the opinion of "hot" is input, and the feedback evaluation value is added as "+1". When the icon of the area 502a is selected, the opinion of "just right" is input, and the feedback evaluation value is added as "0". When the icon of the area 503a is selected, the opinion of "cold" is input, and the feedback evaluation value is added as "-1". The feedback evaluation value corresponding to the opinion of the occupant may be configured to be arbitrarily changed by the system administrator. With this configuration, opinions can be received from users who cannot recognize characters or cannot read the displayed characters. The specific amount to be added once each area is selected is defined numerically and added in positive or negative reports. In addition, the total number of opinions received for all areas is separately counted so that the effect of "0" is not diminished if only the amount of addition is made when each area is selected once, and the result of the addition is commented. A value leveled by the total number of receptions may be defined as a feedback evaluation value.

FIG. 20 is a diagram showing a second modification of the image displayed on the feedback unit 300 of the first embodiment. The area 500b is a specific example of an image displayed to the user from the feedback unit 300. The area 504 is an input unit that receives the user's opinion. Region 504 includes a designated portion of the triangle and a line that can move the designated portion. Region 505 is a meter that expresses an opinion on room temperature. Region 505 includes regions 501b, 502b and 503b that represent opinions about room temperature. Region 501b is a region representing "hot". The region 502b is a region representing "just right". Region 503b is a region representing "cold". The area 506 is an icon in which the feedback unit 300 transmits an opinion to the indicated value determination unit 104. The user moves the indicator to a desired location by manipulating the indicator in area 504 along the line. For example, when the user wants to input "hot" as an opinion, the user moves the indicator to a place adjacent to the area 501b. The user moves the indicator to a desired location and operates the area 506. When the area 506 is operated, the feedback unit 300 transmits the feedback evaluation value to the instruction value determination unit 104. The “hot” feedback evaluation value may differ depending on the location of the region 501b. For example, when the indicator of the area 504 is moved to the upper part of the area 501b, the feedback evaluation value is input as "+3". On the other hand, when the indicator of the area 504 is moved to the lower part of the area 501b, the feedback evaluation value is input as "+1". Alternatively, there may be no leveling of evaluation values within the same area.

Further, the feedback evaluation value for the received input may differ depending on the human attribute. For example, a case where the gender of a human being is known will be described. In the case of men, when the opinion of "hot" is input, the feedback evaluation value is "1", and when the opinion of "just right" is input, the feedback evaluation value is "0" and the opinion of "cold" is input. Then, the feedback evaluation value may be input as "-1". In the case of women, when the opinion of "hot" is input, the feedback evaluation value is "2", and when the opinion of "just right" is input, the feedback evaluation value is "0" and the opinion of "cold" is input. Then, the feedback evaluation value may be input as "-2". In addition, the attribute may be information other than gender. For example, a case where users are classified into two types of attributes, general users and premium members, will be described. In the case of general members, when the opinion of "hot" is input, the feedback evaluation value is "1", and when the opinion of "just right" is input, the feedback evaluation value is "0" and the opinion of "cold". Once entered, the feedback evaluation value may be entered as "-1". For premium members, if the opinion of "hot" is input, the feedback evaluation value is "2", and if the opinion of "just right" is input, the feedback evaluation value is "0", the opinion of "cold" is input. Once entered, the feedback evaluation value may be entered as "-2".

The feedback evaluation value corresponding to the opinion of the occupant may be configured to be arbitrarily changed by the system administrator. The indicated value determining unit 104 may determine whether or not the feedback threshold value is exceeded by making a ratio between the physical quantity and the number of inputs. For example, a case where the feedback evaluation value of "hot" is "Xi", the feedback evaluation value of "just right" is "Yj", and the feedback evaluation value of "cold" is "Zk" will be described. “I, j, k” represent the index numbers of the feedback evaluation values of “hot”, “just right”, and “cold”, respectively. The count of "hot" feedback is Nh. The "just right" feedback count is Nm. The count of "cold" feedback is Nc. The aggregated value using these is obtained based on the following equation (1). The formula (1) is a formula representing an example of a formula for calculating the feedback evaluation value.

In equation (1), the denominators Nh, Nm, and Nc are the sum of the above-mentioned "hot", "just right", and "cold" indexes, and are the counts of each feedback evaluation value. In the formula (1), each term of the numerator is the sum of each feedback evaluation value itself.

The feedback evaluation threshold is determined based on the aggregated value. In addition, when the feedback evaluation values of "hot" and "cold" are weighted, the weight is also included in the count number.

The indicated value determining unit 104 may determine whether or not the feedback evaluation threshold value is exceeded based on the ratio A of various counts. For example, in the case of "hot", when Nh / Nm> A, the indicated value determination unit 104 outputs a temperature control instruction. In the case of "cold", when Nc / Nm> A, the indicated value determining unit 104 outputs a temperature control instruction. In this case, it is preferable to set an initial value for Nm. For example, the initial value may be three times. The ratio A and the initial value may be configured so that the system administrator can arbitrarily change them.

The indicated value determination unit 104 may determine whether or not the feedback evaluation threshold value has been exceeded based on the number of counts. For example, in the case of "hot", when the number of times of Nh exceeds a predetermined number of times and is the same as or exceeds the sum of the number of times of Nm and Nc, the indicated value determining unit 104 may output a temperature control instruction. Good. The predetermined number of times may be configured so that the system administrator can arbitrarily change it.

(Second Embodiment)
Next, the air conditioning control system 100a according to the second embodiment will be described. Hereinafter, the points different from the first embodiment will be described.

FIG. 21 is a functional block diagram showing the overall configuration of the air conditioning control system 100a of the second embodiment. The air conditioning control system 100a is different from the first embodiment in that it includes a feedback determination unit 107, but the other configurations are the same as those of the air conditioning control system 100 in the first embodiment. The feedback evaluation threshold in the first embodiment is hereinafter referred to as a "first threshold".

The feedback determination unit 107 outputs the set temperature instruction to the instruction value determination unit 104 when the feedback evaluation value exceeds the second threshold value a predetermined number of times and the temperature control instruction is not executed from the previous review time to the current time. To convey. The indicated value determining unit 104 receives the second temperature control condition from the indicated condition determining unit 103. Similar to the first temperature control condition, the second temperature control condition defines specific code symbols and numerical values relating to the direction and width for changing the set temperature of the air conditioner 400. The second threshold value may be any value as long as it is a value between the initial value of the feedback evaluation value and the first threshold value. For example, the second threshold value may be half the value of the first threshold value. That is, after the first threshold value is determined by the indicated value determination unit 104, one half of the value may be set as the second threshold value. The predetermined number of times may be any number as long as it can be counted by the feedback determination unit 107. The predetermined number of times is, for example, three times. The second threshold value and the predetermined number of times may be configured so that the system administrator can arbitrarily change them. When the air conditioner 400 has a plurality of air conditioning control areas, the second threshold value may be determined for each air conditioning control area. The second temperature control condition is one aspect of the temperature control condition.

The feedback determination unit 107 determines whether or not the feedback evaluation value exceeds the second threshold value. When the feedback evaluation value exceeds the second threshold value, the feedback determination unit 107 counts the number of times of excess. When the number of excesses exceeds a predetermined number and the temperature control instruction is not executed from the previous review time to the current time, the feedback determination unit 107 transmits to the instruction value determination unit 104 to output the set temperature instruction. To do. The indicated value determination unit 104 determines a new set temperature value based on the current set temperature acquired from the set temperature history value management unit 106 and the second temperature control condition received from the instruction condition determination unit 103, and this new set temperature value is determined. A temperature control instruction including a set temperature value is output to the indicator unit 105. Specifically, the indicated value determination unit 104 adds the new set temperature value to the current set temperature value acquired from the set temperature history value management unit 106 with the second temperature control condition received from the instruction condition determination unit 103. Determine by doing. Between the one review time and the next review time, the second or first temperature control conditions can be output only once, respectively or in combination. When the feedback determination unit 107 outputs the first temperature control condition to the indicated value determination unit 104, the number of times the second threshold value is exceeded is set to 0.

FIG. 22 is a diagram showing a specific example of the second temperature control condition of the second embodiment. The second temperature control condition may have a value different from the first temperature control condition determined by the instruction condition determination unit 103, and a condition relaxed from the first temperature control condition is desirable. For example, when the outside air temperature is 30 ° C. or higher and the amount of solar radiation is 2 MJ / m2 or higher, the instruction condition determination unit 103 outputs a control for lowering the set temperature of the air conditioner 400 by 1 ° C. to the instruction value determination unit 104. Similarly, when the outside air temperature is 30 ° C. or higher and the amount of solar radiation is less than 2 MJ / m2, the instruction condition determination unit 103 outputs control to lower the set temperature of the air conditioner 400 by 0.5 ° C. to the instruction value determination unit 104. To do. It is desirable that the temperature control conditions are defined for each of cooling control and heating control. It may also be defined according to the location of the air conditioning control area. The specific numerical value of the temperature control condition may be configured so that the system administrator can arbitrarily change it. When defined for each air conditioning control area, the air conditioning control area with many windows and the control area adjacent to the doorway are easily affected by outdoor environmental information, and the air conditioning control area without windows and the control area away from the doorway. Can absorb the differences in each air-conditioning control area, such as being less affected by outdoor environment information, and control the temperature. Similar to the second temperature control condition, the second temperature control condition is determined based on the outdoor environment information acquired from the outdoor environment detection unit 204 at each review time.

When the number of times the second threshold value is exceeded exceeds the predetermined number of times and then exceeds the first threshold value during the two consecutive review times, the indicated value determination unit 104 determines that the number of times the second threshold value is exceeded is the predetermined number of times. The difference value between the temperature control instruction condition when the temperature exceeds the above value and the temperature control instruction condition when the first threshold value is exceeded is added to the current set temperature acquired from the set temperature history value management unit 106, and the temperature including the new set temperature is added. It is output to the indicator 105 as a control instruction.

FIG. 23 is a diagram showing a specific example when the cooling control system of the second embodiment is operated in an office. In the cooling control system, the feedback evaluation value is added as a positive direction when it is "hot", a negative direction when it is "cold", and 0 when it is "just right". In FIG. 23, the predetermined number of times required for the feedback determination unit 107 to output the second temperature control condition is three times.

In FIG. 23, the scene determination unit 101 determines the usage scene at 9:00 in the morning. The indicated value determination unit 104 determines the first threshold value and the second threshold value based on the determined usage scene. Further, in the example of FIG. 23, 9:00 am is also the review time. Therefore, the cycle determination unit 102 determines the cycle for determining the next review time based on the number of people information received from the number determination unit 203. Similar to the example of FIG. 11, in the example of FIG. 23, it is determined that the cycle from 9 o'clock to the next review time is all 30 minutes, and the cycle is 9:30, 10 o'clock, ... The review time continues. At the review time, the feedback evaluation value is set to 0, which is the initial value. The review time and the usage scene determination time do not necessarily have to be the same time, but it is desirable to determine the cycle, which is the interval until the next review time, as the usage scene is updated.

In FIG. 23, the feedback evaluation value exceeds the second threshold value between 9:30 and 10:00, but does not exceed the first threshold value. Therefore, the feedback determination unit 107 has an excess number of times from 9:30 to 10:00. Similarly, when the review time is between 10:00 and 10:30 and between 11:00 and 11:30, the feedback evaluation value exceeds the second threshold but does not exceed the first threshold, respectively. It has occurred. Therefore, at 11:30, the number of excesses will be three.

In FIG. 23, the feedback evaluation value exceeds the second threshold value but does not exceed the first threshold value during the review time from 14:00 to 14:30. Therefore, the number of excesses counted by this excess is four, and the number of excesses is larger than the predetermined number. The feedback determination unit 107 outputs the second temperature control condition to the indicated value determination unit 104. The instruction value determination unit 104 determines a new set temperature value from the received second temperature control condition and the current set temperature value, and outputs a temperature control instruction including the new set temperature value to the instruction unit 105. Upon receiving the temperature control instruction, the instruction unit 105 sets the set temperature of the air conditioner 400 to a new set temperature and records it in the set temperature history value management unit 106.

FIG. 24 is a flowchart showing the flow of the temperature setting process for the air conditioner 400 of the second embodiment. The other processing flow is the same as that described in the first embodiment, A in FIG. 24 comes from A in FIG. 15, and B in FIG. 24 continues to B in FIG. The indicated value determining unit 104 acquires a feedback evaluation value from the feedback unit 300 (step S501). The instruction value determination unit 104 determines whether or not the feedback evaluation value is larger than the first threshold value and the temperature control instruction is not executed from the previous review time to the current time (step S502). If it is larger than the first threshold value and the temperature control instruction is not executed from the previous review time to the current time (step S502: Yes), the transition to step S507 occurs. When the temperature control instruction is executed from the first threshold value or less, or from the previous review time to the current time (step S502: No), the transition to step S503 occurs.

The feedback determination unit 107 of the air conditioning control system 100a determines whether or not the feedback evaluation value is larger than the second threshold value (step S503). If the feedback evaluation value is not larger than the second threshold value (step S503: No), the process proceeds to step S512. When the feedback evaluation value is larger than the second threshold value (step S503: Yes), the feedback determination unit 107 counts the number of times the second threshold value is exceeded (step S504). The feedback determination unit 107 determines whether or not the number of times the second threshold value has been exceeded is greater than the predetermined number of times and the temperature control instruction has not been executed from the previous review time to the current time (step S505). When the number of times the second threshold value is exceeded is equal to or less than a predetermined number of times, or when the temperature control instruction is executed from the previous review time to the current time (step S505: No), the transition to step S512 occurs. When the number of times the second threshold value is exceeded is larger than the predetermined number of times and the temperature control instruction is not executed from the previous review time to the current time (step S505: Yes), the feedback determination unit 107 determines the number of times the second threshold value is exceeded. It is set to 0 (step S506).

In the instruction value determination unit 104, when the feedback evaluation value is larger than the first threshold value and the temperature control instruction is not executed from the previous review time to the current time (step S502: Yes), or the feedback evaluation value is the second threshold value. If the temperature control instruction is larger and the temperature control instruction is not executed from the previous review time to the current time (step S505: Yes), the instruction condition determination unit 103 accepts the first temperature control condition or the second temperature control condition (step). S507). The indicated value determination unit 104 adds the first temperature control condition or the second control temperature condition from the current set temperature value, and determines a new set temperature value (step S508). The indicated value determining unit 104 outputs a temperature control instruction including a new set temperature value to the indicated unit 105 (step S509). The indicator 105 sets the set temperature of the air conditioner 400 based on the temperature control instruction (step S510). The instruction unit 105 records the temperature set in the air conditioner 400 based on the temperature control instruction in the set temperature history value management unit 106 (step S511). The air conditioning control system 100 waits until the next program operation timing (step S512).

(Modification example)
When the number of times the second threshold value is exceeded exceeds the predetermined number of times and the case where the first threshold value is exceeded are simultaneously established during the two consecutive review times, the indicator 105 causes the first threshold value to be exceeded. The temperature control instructions may be ignored. Alternatively, the indicated value determination unit 104 manages the set temperature history value of the difference value between the temperature control instruction condition when the number of times the second threshold value is exceeded exceeds a predetermined number of times and the temperature control instruction condition when the first threshold value is exceeded. It may be added to the current set temperature acquired from the unit 106 and output to the instruction unit 105 as a temperature control instruction including a new set temperature.

When the number of times the second threshold value is exceeded exceeds the predetermined number of times and the case where the first threshold value is exceeded are simultaneously established during the two consecutive review times, the indicated value determination unit 104 sets the first threshold value. You may change it. Specifically, the indicated value determining unit 104 may move the value of the first threshold value closer to the initial value of the feedback evaluation value so that the first threshold value approaches the second threshold value. The value to be collected may be configured so that the system administrator can change it arbitrarily.

(Modification example)
The number of times the second threshold value is exceeded, which is counted by the feedback determination unit 107, may be set to 0 at an appropriate timing. For example, it may be when a new scene is determined by the scene determination unit 101, or when the date read from the device on which the program is executed changes. The timing for zeroing the number of times the second threshold value is exceeded may be configured so that the system administrator can arbitrarily change it.

In the air conditioning control system 100a configured in this way, the feedback determination unit 107 sets the second threshold value, so that when there is a mistake in setting the first threshold value as compared with the first embodiment, or when there is a feedback many times. It is possible to alleviate the physical and psychological discomfort of the occupants who do not feel any improvement. Therefore, it is possible to provide a comfortable environment for more occupants.

In each of the above embodiments, the scene determination unit 101, the cycle determination unit 102, the instruction condition determination unit 103, the instruction value determination unit 104, and the instruction unit 105 are software function units, but a hardware function unit such as an LSI is used. There may be.

According to at least one embodiment described above, by having the indicated value determination unit 104, the feedback evaluation value collected from the occupants is reflected in the air conditioner 400, thereby creating a more comfortable environment for the occupants. Can be provided.
