  The storage unit 14 includes a storage device such as a hard disk or a memory, and has a function of storing processing information and programs 14P necessary for various types of processing in the arithmetic processing unit 15. The program 14P is a program that implements various processing units by being read and executed by the arithmetic processing unit 15, and an external device (not shown) or the like via a data input / output function such as the communication I / F unit 11 or the like. It is read in advance from a storage medium (not shown) and stored in the storage unit 14. The main processing information stored in the storage unit 14 includes a first sensor data group 14A, a second sensor data group 14B, a third sensor data group 14C, a first index value 14D, and a second index value 14E. , Third index value 14F, weight information 14G, total index value 14H, threshold information 14I, and air conditioning environment setting value 14J.

  The first index value 14D is an index value according to the state of the air-conditioned environment of the air-conditioned space 660. The first index value 14D is calculated from the first sensor data group 14A. The second index value 14E is an index value according to the evaluation of the person existing in the air-conditioned space 660 with respect to the air-conditioned environment. The second index value 14E is calculated from the second sensor data group 14B. The 3rd index value 14F is an index value according to the state of activity of the person who exists in the air-conditioned space. The third index value 14F is calculated from the third sensor data group 14C. Although the range of the first to third index values 14D to 14F is arbitrary, the following description will be made assuming that the value ranges from 0 to 1.

  The weight information 14G is a numerical value representing the importance of each of the first index value 14D, the second index value 14E, and the third index value 14F. When the weight of the first index value 14D is we, the weight of the second index value 14E is wh, and the weight of the third index value 14F is wp, we + wh + wp = 1 is set.

  The total index value 14H is a total index value calculated from the first index value 14D, the second index value 14E, the third index value 14F, and their weights we, wh, wp. Hereinafter, this comprehensive index value is referred to as QoWL.

  The threshold information 14I is a numerical value representing the lower limit value of the overall index value QoWL.

  The air conditioning environment set value 14J is a set value such as a temperature calculated based on the total index value QoWL. This spatial environment setting value 14J is transmitted from the air conditioning control device 10 to the air conditioning processing device 610 through the communication path L.

  The arithmetic processing unit 15 has a microprocessor such as an MPU and its peripheral circuits, and reads and executes the program 14P from the storage unit 14, thereby realizing various processing units by cooperating the hardware and the program 14P. It has a function to do. As main processing units realized by the arithmetic processing unit 15, a first index value calculation unit 15A, a second index value calculation unit 15B, a third index value calculation unit 15C, a weight setting unit 15D, and a threshold setting unit 15E. , A comprehensive index value calculation unit 15F, and a setting environment calculation unit 15G.

  The first index value calculation unit 15A periodically collects data detected by the first sensor group 630 through the communication I / F unit 11 and the air conditioning processing device 610, and stores the data as the first sensor data group 14A. The unit 14 has a function of saving. The first index value calculation unit 15A reads the first sensor data group 14A from the storage unit 14, calculates the first index value 14D using the read first sensor data group 14A, and stores it. The unit 14 has a function of saving. Hereinafter, details of the first index value calculation unit 15A will be described.

For example, the first index value calculation unit 15A calculates the first index value based on a deviation from a comfortable temperature and humidity range. Specifically, a value of ET * (new effective temperature), which is a kind of thermal index, is calculated, and an index value of 0 or more and 1 or less depending on a deviation from a comfortable range of a predetermined ET * value that is considered comfortable Is calculated. ET * is an index based on a thermal equilibrium formula that can comprehensively evaluate temperature, humidity, airflow, radiation, amount of clothing, and metabolism. The temperature, humidity, airflow, and radiation can be detected by an air temperature sensor, a humidity sensor, an airflow velocity sensor, and an average radiation temperature sensor as the first sensor group 630. In addition, the reference value previously input from the operation input unit 12 is used for the amount of clothing and metabolism. Of course, you may use the sensor which measures the amount of clothes and metabolism. The comfortable range of the ET * value uses a pre-input value. For example, at a summer humidity of 60%, 22.2-24.5 ° C. is a comfortable range. An example of a calculation formula for calculating an index value from the ET * value and its comfort range is shown below. In this calculation formula, it approaches 0 when the deviation is large, and approaches 1 when the deviation is small. That is, it is an indicator that the closer to 1, the more comfortable it is.
1st index value = 1- (22.2-ET *) / ET * if ET * <22.2 ° C
= 1 if 22.2 ℃ <= ET * <24.5 ℃
= 1- (ET * -24.5) /24.5 if 24.5 ℃ <ET * (1-3)… (1)

  Here, ET * (new effective temperature) was used as the thermal index, but instead of ET *, other thermal indices such as working temperature OT, discomfort index DI or THI, effective temperature ET, standard new effective temperature SET *, Predicted average temperature / cool feeling report PMV, wet bulb temperature WBGT, etc. may be used.

  The second index value calculation unit 15B periodically collects data detected by the second sensor group 640 through the communication I / F unit 11 and the air conditioning processing device 610, and stores the data as the second sensor data group 14B. The unit 14 has a function of saving. The second index value calculation unit 15B reads the second sensor data group 14B from the storage unit 14, calculates the second index value 14E using the read second sensor data group 14B, and stores it. The unit 14 has a function of saving. Details of the second index value calculation unit 15B will be described below.

  FIG. 4A shows a configuration example of a display screen of a tablet terminal as the second sensor group 640 used by the second index value calculation unit 15B. As shown in the figure, three types of buttons “hot”, “comfortable”, and “cold” are displayed on the display screen of the tablet terminal, and when a person in the air-conditioned space 660 presses any button, The hot / cold / comfortable subjective evaluation result is notified to the air conditioning processing device 610 via the network, and is further notified from the air conditioning processing device 610 to the air conditioning control device 10 through the communication path L. The second index value calculation unit 15B acquires and indexes the number of notifications acquired within a certain time (for example, 5 minutes).

FIG. 4B shows definitions of variables N0, N1, N2, and N3 used internally by the second index value calculation unit 15B and three cases. N0, N1, N2, and N3 are flagged according to the number of “hot” or “cold” times. For example, Case 1 is a case where there are two people who evaluate that it is hot within a certain time, 1 is set to N2, and 0 is set to the other values. Case 2 is set to N3 when there are 3 or more people who evaluate that it is hot. Even if 4 or 6 people evaluate that it is hot, 1 is set in N3. Case 3 is a case where one person evaluated as comfortable within a certain time and one person evaluated as cold. In the calculation of the second index value, as shown in the following expression, the value of N0 is not used, and any one or combination of N1, N2, and N3 is used.
Second index value = 1- (3 * N3 + 2 * N2 + 3 * N3) / 3 * (N3 + N2 + N1) (2)

  For each of Cases 1-3, find the second index value using Equation (2). In Case 1, 1- (0 + 2 + 0/3 * (1 + 0 + 0) = 1/3 = approximately 0.33. In Case 2, 1- (3 * 1 + 0 + 0 ) / 3 * (1 + 0 + 0) = 0 In the case of Case 3, 1− (0 + 0 + 1) / 3 * (0 + 0 + 1) = 2/3 = about 0.67. If there is no notification, the value is 1 when only a comfortable button is pressed.

  The third index value calculation unit 15C periodically collects data detected by the third sensor group 650 through the communication I / F unit 11 and the air conditioning processing device 610, and stores the data as the third sensor data group 14C. The unit 14 has a function of saving. The third index value calculation unit 15C reads the third sensor data group 14C from the storage unit 14, calculates the third index value 14F using the read third sensor data group 14C, and stores it. The unit 14 has a function of saving. Details of the third index value calculation unit 15C will be described below.

When the third index value calculation unit 15C calculates an index value according to the status of the meeting as the third index value according to the activity state of the person existing in the air-conditioned space 660, the third sensor group 650 A human detection sensor that measures the status of the meeting is used. Specifically, if the air-conditioned space 660 has a size of 8 m × 12 m, for example, as shown in FIG. 5, it is divided into 24 blocks of 2 m × 2 m, for example, and a human detection sensor is installed for each block. The presence / absence, number, and position of people in the block are detected by a human detection sensor. By cooperation between human detection sensors, it is possible to measure the distance between people even across blocks. The third index value calculation unit 15C assumes that the discussion is performed when the distance between the two persons is within 2 meters, and calculates the ratio of the number of blocks being discussed as shown in the following equation: The index value.
Third index value = number of blocks under discussion / total number of blocks (3-1)

  In FIG. 5, it is assumed that the discussion is performed in a place surrounded by a dotted line. A person in an unenclosed area cannot detect another person within 2 meters of the surrounding area, so it is not discussed. In this case, it is assumed that 5 of 24 blocks are being discussed, and 5/24 = about 0.208 is the third index value.

When the third index value calculation unit 15C calculates the index value according to the program creation as the third index value according to the state of the activity of the person existing in the air-conditioned space 660, the third sensor group 650 As described above, a program for periodically acquiring and notifying program line number data is used. Specifically, the number n of lines is acquired from the target program file in the storage, and the program to be notified is operated. The third index value calculation unit 15C sets the target program line number N, and calculates the third index value from the values of n and N using the following equation.
Third index value = 1- (Nn) / N if N> n
= 1 if N <= n (3-2)

  For example, when the target number of lines is 100 and the acquired number-of-rows data is 50, the third index value is 0.5. In the above description, the third index value is the number of lines in the program file, but it may be the number of lines added per unit time.

  The weight setting unit 15D has a function of determining the weights we, wh, and wp of the first to third index values and storing them in the storage unit 14 as the weight information 14G.

  FIG. 6 shows a configuration example of a weight setting screen displayed on the screen display unit 13 by the weight setting unit 15D. The weight setting screen 131 includes an input field 132 for the first index value weight we, an input field 133 for the second index value weight wh, an input field 134 for the third index value weight wp, and a setting button 135. It is displayed. The operator operates the operation input unit 12 to input numerical values in the input fields 132 to 134 and then presses the setting button 135. At this time, the operator inputs a numerical value in which the sum is 1 and each value is 0 or more and 1 or less in each input column. The weight setting unit 15D stores the numerical values input in the input fields 132 to 134 in the storage unit 14 as the weight information 14G of the weights we, wh, and wp.

  In the above example, the weight setting unit 15D receives the weight information from the operator of the air conditioning control device 10, but may input the weight information from a remote terminal device connected through the communication I / F unit 11. Good.

  The threshold value setting unit 15E has a function of determining a threshold value to be compared with the comprehensive index value and storing the threshold value information 14I in the storage unit 14. Similarly to the weight setting unit 15D, the threshold setting unit 15E may be configured to store values input from the operator through the graphical user interface in the storage unit 14 as threshold information 14I.

The total index value calculation unit 15F reads the first to third index values 14D to 14F and the weight information 14G from the storage unit 14, calculates the total index value QoWL based on the information, and calculates the total index value 14H. As a storage function in the storage unit 14. For example, the total index value calculation unit 15F calculates the total index value QoWL by weighted addition of each index value as shown in the following equation.
Total index value = Σ (each index weight * each index value) (4)
Here, each index value is the first to third index values, and each index weight is we, wh, wp.

  The setting environment calculation unit 15G reads the first to third index values 14D to 14F, the total index value 14H, and the threshold information 14I from the storage unit 14, and based on these information, the air conditioning environment setting value of the air conditioning space 660 It has the function to calculate. The setting environment calculation unit 15G has a function of transmitting the calculated air conditioning environment setting value to the air conditioning processing device 610 through the communication I / F unit 11.

  Next, the operation of the air conditioning control system according to this embodiment will be described.

  The air conditioning processing device 610 starts control of the air conditioning equipment 620 at the start of the operation of the air conditioning system 600, for example, according to the set temperature that is the air conditioning environment setting value received and held from the air conditioning control device 10 immediately before the previous operation stop. In addition, the air conditioning processing device 610 receives and holds sensor data output from the first to third sensor groups 630 to 650, and transmits the data to the air conditioning control device 10 through the communication path L spontaneously or according to a request. In addition, when the air conditioning processing device 610 receives the air conditioning environment setting value from the air conditioning control device 10 through the communication path L, the air conditioning processing device 610 retains the received air conditioning environment setting value and controls the air conditioning equipment 620 according to the retained air conditioning environment setting value. In this way, the air conditioning processing device 610 controls the air conditioning equipment 620 so that the temperature of the air conditioned space 660 matches the set temperature that is the air conditioning environment setting value received from the air conditioning control device 10.

  On the other hand, when the air-conditioning control device 10 is activated, execution of the processing shown in FIG.

  First, the weight setting unit 15D determines the values of the weights we, wh, and wp of the first to third index values and stores them as weight information 14G in the storage unit 14 (step S101). Next, the threshold value setting unit 15E determines a threshold value for comparison with the comprehensive index value, and stores it as threshold information 14I in the storage unit 14 (step S102).

  Next, 15 A of 1st index value calculation parts acquire the data detected by the 1st sensor group 630 from the air-conditioning processing apparatus 610, and preserve | save in the memory | storage part 14 as 14 A of 1st sensor data groups (step). S103). Subsequently, the first index value calculation unit 15A calculates the first index value 14D using the first sensor data group 14A, and stores it in the storage unit 14 (step S104).

  Next, the 2nd index value calculation part 15B acquires the data detected by the 2nd sensor group 640 from the air-conditioning processing apparatus 610, and preserve | saves it in the memory | storage part 14 as the 2nd sensor data group 14B (step). S105). Subsequently, the second index value calculation unit 15B calculates the second index value 14E using the second sensor data group 14B, and stores it in the storage unit 14 (step S106).

  Next, the third index value calculation unit 15C acquires the data detected by the third sensor group 650 from the air conditioning processing device 610, and stores it in the storage unit 14 as the third sensor data group 14C (step S1). S107). Subsequently, the third index value calculation unit 15C calculates the third index value 14F using the third sensor data group 14C, and stores it in the storage unit 14 (step S108).

  Next, the total index value calculation unit 15F calculates a total index value QoWL based on the first to third index values 14D to 14F and the weight information 14G, and stores the total index value QoWL in the storage unit 14 as a total index value 14H. (Step S109).

  Next, the setting environment calculation unit 15G determines whether or not the total index value QoWL is equal to or greater than the threshold given by the threshold information 14I (step S110). If the total index value QoWL is less than the threshold value, the setting environment calculation unit 15G calculates the spatial environment setting value so that the total index value QoWL is equal to or greater than the threshold value (step S111). Then, the setting environment calculation unit 15G stores the calculated air conditioning environment setting value in the storage unit 14 as the spatial environment setting value 14J, and transmits it to the air conditioning processing device 610 through the communication path L (step S112). On the other hand, if the total index value QoWL is greater than or equal to the threshold value, the setting environment calculation unit 15G does not perform the processes of steps S111 and S112.

  Thereafter, the weight setting unit 15D determines whether or not a request for changing the condition has occurred (step S113). For example, when detecting that the operator has performed a predetermined operation on the operation input unit 12, the weight setting unit 15 </ b> D determines that a request to change the condition has occurred. Alternatively, when the condition setting request message is received through the communication I / F unit 11, the weight setting unit 15D determines that a request for changing the condition has occurred. When the weight setting unit 15D detects that a request to change the condition has occurred, the weight setting unit 15D returns the control to step S101. Thereby, the weight of each index value and the threshold value of the total index value are reset to values different from the current values, and the control is continued. If the condition change request is not generated, the weight setting unit 15D returns the control to step S103. Thereby, control is continued using the present weight and threshold.

  FIG. 8 is a flowchart showing details of step S111 in FIG. First, the setting environment calculation unit 15G determines whether or not the weight wp of the third index value is the largest among the three weights (step S121). When the weight wp of the third index value is not the maximum, the setting environment calculation unit 15G determines whether or not the weight we of the first index value is greater than or equal to the weight wh of the second index value (step S122).

  If we ≧ wh (YES in step S122), the setting environment calculation unit 15G preferentially improves the first index value having the largest weight so that the total index value QoWL becomes equal to or greater than the threshold value. To do. First, the setting environment calculation unit 15G determines whether or not the value of the first index value 14D used for calculating the total index value QoWL is smaller than 1 (step S123). If the value of the first index value 14D is smaller than 1, the setting environment calculation unit 15G calculates a new spatial environment setting value so that the first index value increases (step S124). For example, in the present embodiment, since the first index value is an index of deviation of the ET * value from the comfortable range, what is the ET * value that matches the comfortable range when the temperature of the conditioned space 660 is increased? , And such a temperature or an intermediate temperature between such a temperature and the current set temperature is set as a new set temperature.

  On the other hand, if the value of the first index value 14D is not smaller than 1, further improvement of the first index value cannot be expected. Therefore, the setting environment calculation unit 15G does not set the weight wh of the second index value to be 0. If (NO in step S125) and the second index value is smaller than 1 (YES in step S126), a new spatial environment setting value is calculated so that the second index value increases (step S127). Since the second index value is an index of human evaluation of the spatial environment, it is estimated how the temperature can be increased or decreased to improve the evaluation. For example, in the case of Case 1 and Case 2 in FIG. 4B, if the set temperature is lowered, the number of evaluations that are hot is reduced, and the second index value is increased. For this reason, a temperature lower than the current set temperature by a predetermined temperature is calculated as a new set temperature. In addition, the setting environment calculation unit 15G determines whether the weight wh of the second index value is 0 (YES in step S125), or if the second index value is not smaller than 1 even if it is not 0 (NO in step S126). Since further improvement of the second index value cannot be expected, the air-conditioning environment set value is kept the same as the current state (step S128).

  If the setting environment calculation unit 15G is not we ≧ wh (NO in step S122), the setting environment calculation unit 15G preferentially improves the second index value having the largest weight, thereby obtaining a comprehensive index value. Make QoWL equal to or greater than the threshold. First, the setting environment calculation unit 15G determines whether or not the value of the second index value 14E used for calculating the total index value QoWL is smaller than 1 (step S129). If the value of the second index value 14E is smaller than 1, the setting environment calculation unit 15G calculates a new spatial environment setting value so that the second index value increases (step S127). If the value of the second index value 14E is not smaller than 1, further improvement of the second index value cannot be expected, so the setting environment calculation unit 15G does not have the weight we of the first index value not 0 (step If NO in S130 and the first index value is smaller than 1 (YES in Step S131), a new spatial environment setting value is calculated so that the first index value increases (Step S124). Further, the setting environment calculation unit 15G determines whether the weight we of the first index value is 0 (YES in step S130), or if it is not 0, the first index value is not smaller than 1 (NO in step S131). Since further improvement of the first index value cannot be expected, the air conditioning environment setting value is kept the same as the current state (step S128).

  In addition, when the weight wp of the third index value is maximum (YES in step S121), the setting environment calculation unit 15G improves the third index value preferentially, so that the total index value QoWL becomes equal to or greater than the threshold value. Like that. In the present embodiment, the third index value is improved by improving the second index value based on the knowledge that when the degree of satisfaction with warm feeling is high, the result of the intellectual work is good, the overall index value QoWL To be greater than or equal to the threshold. First, the setting environment calculation unit 15G determines whether or not the value of the second index value 14E used for calculating the total index value QoWL is smaller than 1, and whether or not the weight wh of the second index value is 0 ( Steps S132 and S133). Then, the setting environment calculation unit 15G calculates a new spatial environment setting value so that the second index value increases if the value of the second index value 14E is smaller than 1 and the weight wh is not 0. (Step S127). On the other hand, if the second index value is not smaller than 1 or the weight wh is 0 even if the second index value is smaller than 1, the setting environment calculation unit 15G can not expect further improvement of the second index value. The air-conditioning environment set value remains unchanged (step S128). Note that the set temperature may be intentionally increased / decreased over a certain period instead of the air conditioning environment set value that is the same as the current value.

  Thus, according to this embodiment, the balance of a plurality of indexes can be changed in air conditioning control based on a plurality of indexes. The reason for this is that the air conditioning control device 10 calculates a comprehensive index value from a plurality of index values and a weight for each index value, and sets an air conditioning environment setting value of the air-conditioned space 660 of the air conditioning system 600 based on the total index value. It is for calculating.

  For example, if we = 1, wh = 0, and wp = 0 as the weights of the first to third index values, air conditioning control that greatly depends on the first index value can be performed, and we = 0, wh = 1, wp When = 0, air-conditioning control that greatly depends on the second index value can be performed, and when we = 0, wh = 0, and wp = 1, air-conditioning control that largely depends on the third index value can be performed. Although an extreme example has been given so that the effect of the present embodiment can be easily understood, it is obvious that the above effect can be obtained even when a weight other than the above exemplified values is set.

Is set to be

  The arithmetic processing unit 25 has a microprocessor such as an MPU and its peripheral circuits, and reads and executes the program 24P from the storage unit 24, thereby realizing various processing units by cooperating the hardware and the program 24P. It has a function to do.

  Next, the operation of the air conditioning control system according to this embodiment will be described.

  The air conditioning processing device 710 starts control of the air conditioning equipment 720 according to the set temperature, which is the air conditioning environment setting value received and held from the air conditioning control device 20 immediately before the previous operation stop, for example, when the air conditioning system 700 starts to operate.

In addition, when the air conditioning processing device 710 receives the air conditioning environment setting value from the air conditioning control device 20 through the communication path L, the air conditioning processing device 710 retains the received air conditioning environment setting value and controls the air conditioning equipment 720 according to the retained air conditioning environment setting value. In this way, the air conditioning processing device 710 controls the temperature of the air-conditioned space 760 so as to coincide with the set temperature that is the air-conditioning environment setting value received from the air-conditioning control device 20.

  On the other hand, when the air-conditioning control device 20 is activated, execution of the processing shown in FIG.

  First, the weight setting unit 25D creates weight change schedule information 24N and stores it in the storage unit 24 (step S201). Thereafter, the weight setting unit 25D periodically repeats the operation of updating the weight information 24G according to the weight change schedule information 24N. Details of this operation will be described later. Next, the threshold value setting unit 25E determines a threshold value to be compared with the comprehensive index value, and stores it as threshold information 24I in the storage unit 24 (step S202).

  Next, the first index value calculation unit 25A acquires the data detected by the first sensor group 730 from the air conditioning processing device 710, and stores it in the storage unit 24 as the first sensor data group 24A (step) S203). Subsequently, the first index value calculation unit 25A calculates the first index value 24D using the first sensor data group 24A, and stores it in the storage unit 24 (step S204).

  Next, the 2nd index value calculation part 25B acquires the data detected by the 2nd sensor group 740 from the air-conditioning processing apparatus 710, and preserve | saves it in the memory | storage part 24 as the 2nd sensor data group 24B (step). S205). Subsequently, the second index value calculation unit 25B calculates the second index value 24E using the second sensor data group 24B, and stores it in the storage unit 24 (step S206).

  Next, the third index value calculation unit 25C acquires data detected by the third sensor group 750 from the air conditioning processing device 710, and stores it in the storage unit 24 as the third sensor data group 24C (step S40). S207). Subsequently, the third index value calculation unit 25C calculates the third index value 24F using the third sensor data group 24C, and stores it in the storage unit 24 (step S208).

  Next, the fourth index value calculation unit 25H acquires data detected by the wattmeter 770 from the air conditioning processing device 710, and stores it in the storage unit 24 as power consumption information 24K (step S209). Subsequently, the fourth index value calculation unit 25H calculates the fourth index value 24M using the power consumption information 24K and the power upper limit value 24L, and stores it in the storage unit 24 (step S210).

  Next, the total index value calculation unit 25F calculates a total index value QoWL ′ based on the first to fourth index values 24D to 24F and 24M and the weight information 24G, and stores the total index value QoWL ′ as the total index value 24H. (Step S211).

  Next, the setting environment calculation unit 25G determines whether or not the total index value QoWL ′ is equal to or greater than the threshold given by the threshold information 24I (step S212). If the total index value QoWL ′ is less than the threshold, the setting environment calculation unit 25G calculates the spatial environment setting value so that the total index value QoWL ′ is equal to or greater than the threshold (step S213). Then, the setting environment calculation unit 25G stores the calculated air conditioning environment setting value in the storage unit 24 as the spatial environment setting value 24J, and transmits it to the air conditioning processing device 710 through the communication path L (step S214). On the other hand, if the total index value QoWL ′ is equal to or greater than the threshold value, the setting environment calculation unit 25G does not perform the processes of steps S213 and S214.

  Thereafter, the weight setting unit 25D determines whether or not a request for changing the condition has occurred (step S215). For example, when detecting that the operator has performed a predetermined operation on the operation input unit 22, the weight setting unit 25 </ b> D determines that a request to change the condition has occurred. Alternatively, when the weight setting unit 25D receives the condition change request message through the communication I / F unit 21, it determines that a request for changing the condition has occurred. When the weight setting unit 25D detects that a request to change the condition has occurred, the weight setting unit 25D returns the control to step S201. Thereby, the weight change schedule information and the threshold value of the comprehensive index value are reset to values different from the current values, and the control is continued. If the condition change request is not generated, the weight setting unit 25D returns the control to step S203. As a result, the control is continued using the current weight change schedule information and the threshold value.

  FIG. 14 is a flowchart showing details of step S213 in FIG. First, the setting environment calculation unit 25G determines whether or not the weight ws of the fourth index value is the largest of the four weights (step S221). When the weight ws of the fourth index value is not the maximum, the setting environment calculation unit 25G performs the same process as the process illustrated in FIG. 8 (Step S222). On the other hand, if the weight ws of the fourth index value is maximum, the setting environment calculation unit 25G calculates a new space environment setting value so that the power consumption of the air conditioning system 700 is reduced by a unit amount (step S223). . That is, the set temperature is increased by a unit amount (for example, 1 ° C.) during cooling, and the set temperature is decreased by a unit amount during heating.

  On the other hand, the weight setting unit 25D performs the process shown in FIG. 15 at predetermined time intervals (for example, every minute) in parallel with the process shown in FIG. First, the weight setting unit 25D refers to the weight change schedule information 24N stored in the storage unit 24, and acquires the weight of the current time (step S231). For example, if the current time is 13:01, the weight setting unit 25D acquires we = 0.2, wh = 0.1, wp = 0.2, and ws = 0.5 from the weight change schedule information 24N in FIG. Next, the weight setting unit 25D compares the weight information 24G stored in the storage unit 24 with the acquired weight (step S232). If the two match, the weight setting unit 25D ends the process of FIG. On the other hand, if they are different, the weight setting unit 25D overwrites and updates the weight information 24G in the storage unit 24 with the acquired weight (step S233). Then, the current process in FIG. 15 ends.

  Thus, according to this embodiment, the balance of a plurality of indexes can be changed in air conditioning control based on a plurality of indexes. The reason is that the air conditioning control device 20 calculates a total index value from a plurality of index values and the weight for each index value, and sets the air conditioning environment setting value of the air conditioning space 760 of the air conditioning system 700 based on the total index value. It is for calculating.

  For example, if we = 1, wh = 0, wp = 0, ws = 0 as the weights of the first to fourth index values, air-conditioning control greatly depending on the first index value can be performed, and we = 0, wh = 1, wp = 0, ws = 0, air-conditioning control greatly depends on the second index value, and if we = 0, wh = 0, wp = 1, ws = 0, it becomes larger to the third index value. The air conditioning control depending on the third index value can be performed if we = 0, wh = 0, wp = 0, and ws = 1. Although an extreme example has been given so that the effect of the present embodiment can be easily understood, it is obvious that the above effect can be obtained even when a weight other than the above exemplified values is set.

  Moreover, according to this embodiment, the balance of a plurality of indexes can be automatically changed according to a predetermined schedule. The reason is that the weight setting unit 25D updates the weight information 24G according to the weight change schedule information 24N.
