  Hereinafter, an air conditioning control device and an air conditioning control method according to an embodiment of the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration example of an air conditioning control system 10 according to Embodiment 1 of the present invention. The air conditioning control system 10 includes air conditioners 1-1 and 1-2, portable terminals 2-1 and 2-2, an air conditioning control device 3, and position measuring devices 4-1 and 4-2. The air conditioning control device 3 is connected to an air conditioning network in which the air conditioners 1-1 and 1-2 are connected by the communication line 6. The air conditioning network is a network including the air conditioners 1-1 and 1-2. However, the air conditioning network including the air conditioning control device 3 connected by the communication line 6 may be used. The portable terminals 2-1 and 2-2 possessed by the resident are connected to the air conditioning control device 3 by wireless communication. As a wireless communication system, for example, there is a wireless local area network (LAN), but is not limited thereto. The position measuring devices 4-1 and 4-2 are connected to the mobile terminals 2-1 and 2-2 and the air conditioning control device 3 by wireless communication. The position measuring devices 4-1 and 4-2 measure communication radio wave intensity in wireless communication with the mobile terminals 2-1 and 2-2 and transmit information on the communication radio wave intensity to the air conditioning control device 3.

  Note that the air conditioning control system 10 separately includes devices included in a general air conditioning control system, such as an air conditioner remote controller, and description thereof is omitted in the present embodiment. In the following description, when the air conditioners 1-1 and 1-2 are not distinguished from each other, the air conditioner 1 is referred to as the air conditioner 1. When the mobile terminals 2-1 and 2-2 are not distinguished from each other, the air conditioner is referred to as the mobile terminal 2. When 1 and 4-2 are not distinguished, they are referred to as a position measuring device 4.

  FIG. 2 is a block diagram illustrating a configuration example of the air conditioning control device 3 according to the first embodiment. The air conditioning control device 3 includes an air conditioning control adjustment unit 31, an air conditioning evaluation calculation unit 32, an air conditioning operation acquisition unit 33, and a resident position calculation unit 34.

  The air conditioning control adjustment unit 31 transmits a control signal to the air conditioner 1 via the communication line 6 to control the operation of the air conditioner 1.

  The air conditioning evaluation calculation unit 32 calculates an evaluation value of the comfort of the resident in the air conditioned space. Specifically, the air conditioning evaluation calculation unit 32 is the air conditioning evaluation value for the current air conditioning control of the resident who stayed in the air conditioning space for a longer period than the specified period in the period in which the current air conditioning control is being executed in the air conditioner 1. Is used to calculate the air conditioning evaluation value used when determining the content of the air conditioning control of the air conditioner 1. The period during which the current air conditioning control is being executed is the first period, and the specified period is the second period. The first period ≧ the second period. In addition, the air conditioning evaluation value for the resident's current air conditioning control is set as the first air conditioning evaluation value, and the air conditioning evaluation value used in determining the content of the air conditioning control of the air conditioner 1 is set as the second air conditioning evaluation value. .

  The air conditioning operation acquisition unit 33 acquires the internal state value of the air conditioner 1 via the communication line 6. The internal state value includes the suction temperature of the air conditioner 1, the humidity around the air conditioner 1, the internal control value of the air conditioner 1 in the current air conditioning control, and the like. The internal control value is, for example, a thermo-off time period, an operation time period of each air conditioner 1 when a plurality of air conditioners 1 are rotated.

  The resident position calculation unit 34 collects the communication radio wave intensity of the mobile terminal 2 from the position measurement device 4 and calculates the position of the mobile terminal 2 using the communication radio wave intensity, thereby the occupant possessing the mobile terminal 2, That is, the position of the resident in the air-conditioned space that is controlled by the air conditioner 1 is calculated.

  The configuration of the air conditioning evaluation calculation unit 32 will be described. The air conditioning evaluation calculation unit 32 includes an operation cycle calculation unit 321, a steady state determination unit 322, a stay time calculation unit 323, an air conditioning evaluation target extraction unit 324, and a occupant comfort counting unit 325.

  The operation cycle calculation unit 321 calculates the indoor temperature fluctuation cycle, that is, the operation cycle of the air conditioner 1 using the suction temperature included in the internal state value of the air conditioner 1 acquired from the air conditioning operation acquisition unit 33. The operation cycle of the air conditioner 1 is the above-described second period. The second period may be a fluctuation cycle of the humidity around the air conditioner 1 caused by the current air conditioning control, or may be a fluctuation cycle of the internal control value of the air conditioner 1 in the current air conditioning control.

  The steady state determination unit 322 determines whether or not the state of the air-conditioned space is a steady state after changing the content of the air conditioning control of the air conditioner 1. In the steady state, after changing the content of the air conditioning control of the air conditioner 1, the state of the air-conditioned space has reached the target condition of the air-conditioning control, or the fluctuation amount is defined within the target condition. State. The steady state determination unit 322 uses, for example, the suction temperature of the air conditioner 1 acquired from the air conditioning operation acquisition unit 33 to determine whether the suction temperature has reached the target condition, that is, the target temperature, or whether the suction temperature fluctuation amount is the target. It is determined whether or not the temperature is within a specified range. The steady state determination unit 322 determines that the steady state has been reached when the suction temperature reaches the target temperature or when the amount of fluctuation of the suction temperature falls within a range defined for the target temperature. The first period described above is a period excluding a period from when the content of the air conditioning control of the air conditioner 1 is changed to when it reaches a steady state, and is a period from when the steady state is reached until now.

  The stay time calculation unit 323 calculates the stay time of the resident in the air-conditioned space using the position information calculated by the resident position calculation unit 34.

  The air-conditioning evaluation target extraction unit 324 extracts the resident who is the target of the evaluation of the air-conditioning control from the operation cycle and the staying time of each resident in the steady state.

  The resident comfort totalization unit 325 totals the air conditioning evaluation values input to the mobile terminal 2 by the extracted occupants, and calculates the air conditioning evaluation values used when determining the content of the air conditioning control of the air conditioner 1. . In other words, the occupant comfort totaling unit 325 calculates the second air conditioning evaluation value using the first air conditioning evaluation value.

  Subsequently, the operation of the air conditioning control device 3 will be described. In addition, here, a thermal sensation that means the degree of “hot” or “cold” is used as the air conditioning evaluation value that is an evaluation of the air conditioning control of the resident, that is, the first air conditioning evaluation value and the second air conditioning evaluation value. In addition, an operation when the air conditioning control device 3 performs the same control on all the air conditioners 1 on the office floor where the plurality of air conditioners 1 are arranged will be described. FIG. 3 is a flowchart showing the operation of the air conditioning control device 3 according to the first embodiment.

  The resident position calculation unit 34 acquires the communication radio wave intensity in the wireless communication with each portable terminal 2 from the position measurement device 4 (step S1), and calculates the position of the resident who owns the portable terminal 2 (step S2). . The resident position calculation unit 34 derives the distance between the portable terminal 2 and the position measuring device 4 from the relational expression between the radio wave intensity and the distance, for example, as a method of calculating the resident position from the communication radio wave intensity. The position is determined by surveying. The resident position calculation unit 34 may determine the vicinity of the position measuring device 4 having the strongest communication radio wave intensity as the position of the mobile terminal 2, that is, the position of the resident. The air conditioning operation acquisition unit 33 acquires the indoor air suction temperature from the air conditioner 1 (step S3). The air conditioning evaluation calculation unit 32 collects the thermal sensation of the resident input to the portable terminal 2, that is, the first air conditioning evaluation value (step S4).

  The air conditioning evaluation calculation unit 32 uses the history of the suction temperature, the history of the occupant position, and the first air conditioning evaluation value of the occupant to sense the thermal sensation of the entire air conditioning space that is the air conditioning control target of the air conditioning control system 10. The process which calculates the air-conditioning evaluation value which shows, ie, the 2nd air-conditioning evaluation value, is performed (step S5). Note that the air conditioning evaluation calculation unit 32 may not calculate the second air conditioning evaluation value, such as when the air conditioning control adjustment unit 31 is not in a steady state immediately after changing the content of the air conditioning control. The detailed operation of step S5 in the air conditioning evaluation calculation unit 32 will be described later.

  The air conditioning control adjustment unit 31 determines the content of the air conditioning control of the air conditioner 1 using the second air conditioning evaluation value calculated by the air conditioning evaluation calculation unit 32. Here, when the second air conditioning evaluation value is not calculated by the air conditioning evaluation calculation unit 32, such as immediately after the content of the previous air conditioning control is changed (step S6: No), the air conditioning control adjustment unit 31 The process ends without changing the content of the air conditioning control. If the air conditioning evaluation calculation unit 32 has calculated the air conditioning evaluation value (step S6: Yes), the air conditioning control adjustment unit 31 checks the content of the second air conditioning evaluation value (step S7).

  When the content of the second air conditioning evaluation value is “cold” (step S7: cold), the air conditioning control adjustment unit 31 determines to raise the set temperature by 0.5 ° C. as the content of the air conditioning control, and sets the set temperature to 0. The air conditioner 1 is instructed to raise the temperature by 5 ° C. (step S8). When the content of the second air conditioning evaluation value is “comfortable” (step S7: comfortable), the air conditioning control adjustment unit 31 does not change the set temperature (step S9). In this case, the air conditioning control adjustment unit 31 ends the process without changing the content of the air conditioning control of the air conditioner 1 as in the case of step S6: No. When the content of the second air conditioning evaluation value is “hot” (step S7: hot), the air conditioning control adjustment unit 31 determines to lower the set temperature by 0.5 ° C. as the content of the air conditioning control, and sets the set temperature to 0. The air conditioner 1 is instructed to set the temperature lowered by 5 ° C. (step S10). The air conditioning control device 3 repeatedly executes the processing of the flowchart shown in FIG. 3 at specified time intervals.

  In addition, you may use the unpleasant person rate which shows the ratio of the resident who feels unpleasant instead of a thermal sensation as an air-conditioning evaluation value which is evaluation with respect to an air-conditioning control of a resident. The air conditioning control adjustment unit 31 includes, for example, a control list in which a plurality of air conditioning control contents arranged in advance in the order in which comfort is considered to be high are described. When the unpleasant person rate is higher than the prescribed threshold, the air conditioning control adjustment unit 31 sets, that is, instructs the air conditioner 1 on the air conditioning control content for which the unpleasant person rate is lowered by one in the control list. When the unpleasant person rate is lower than the prescribed threshold, the air conditioning control adjustment unit 31 sets, that is, indicates to the air conditioner 1 the air conditioning control content that increases the unpleasant person rate by one in the control list.

  Next, the operation of step S5 in the air conditioning evaluation calculation unit 32 will be described in detail. FIG. 4 is a flowchart showing the operation of the air conditioning evaluation calculation unit 32 according to the first embodiment.

  The steady state determination unit 322 refers to the suction temperature history and determines whether or not the current air conditioning control state is a steady state (step S21). For example, the steady state determination unit 322 determines that the suction temperature is not increasing or decreasing when the suction temperature is increasing or decreasing during the specified period. If the suction temperature is neither increasing nor decreasing during the specified period, for example. Determined as steady state. The steady state determination unit 322 compares the average value of the suction temperature of the first 15 minutes with the average value of the suction temperature of the second half 15 minutes when the specifically specified period is 30 minutes, and the difference is ± 1. If it is in the range of ° C., an operation for determining a steady state can be considered. When the current state of the air conditioning control is determined to be the steady state (step S22: Yes), the steady state determination unit 322 notifies the operation cycle calculation unit 321 that the current state of the air conditioning control is the steady state.

  The operation cycle calculation unit 321 refers to the history of the suction temperature, searches for a portion where the suction temperature periodically changes within a specified period, and calculates the change cycle as the operation cycle (step S23).

  FIG. 5 is a diagram illustrating a specific example of an operation in which the operation cycle calculation unit 321 according to Embodiment 1 calculates the operation cycle. For example, when the specified period is 30 minutes, the operation cycle calculation unit 321 first searches for a place where the suction temperature periodically changes in 30 minutes. The place where the suction temperature periodically changes is any one of the plurality of air conditioners 1. When the location where the suction temperature changes periodically is found, the operation cycle calculation unit 321 calculates the average temperature for 30 minutes at the found location. The operation cycle calculation unit 321 obtains the time at which the suction temperature becomes the average temperature in 30 minutes, and calculates the time width between the times at which the suction temperature becomes the average temperature. The operation cycle calculation unit 321 calculates the calculated time width, an average value of the time widths # 1 to # 6 in the example of FIG. 5, and calculates a value obtained by doubling the calculated average value as the operation cycle. As shown in FIG. 5, the average value is doubled, as shown in FIG. 5, the suction temperature is alternately up and down with respect to the average temperature, and the time width above and below the average temperature is set to 1 of the operation cycle. This is to make it a cycle. Note that the calculation method shown in FIG. 5 is an example, and the present invention is not limited to this. In the calculation of the operation cycle, the operation cycle calculation unit 321 may use the humidity around the air conditioner 1 included in the internal state value or the internal control value of the air conditioner 1 in the current air conditioning control, instead of the suction temperature. .

  The stay time calculation unit 323 extracts a resident in the air-conditioned space from the current position information of each resident calculated by the resident position calculation unit 34 (step S24). Specifically, the stay time calculation unit 323 stores the arrangement of the air conditioner 1 controlled by the air conditioning control device 3 in the floor, and a resident is included within a certain distance from the air conditioner 1, for example, within 3 m. If it is in a conditioned space.

  The stay time calculation unit 323 refers to the history of past location information of each resident, and the air conditioning control adjustment unit 31 changes the content of the previous air conditioning control in the process of step S8 or step S10 in the flowchart of FIG. Then, after the time when the steady state determination unit 322 determines that the steady state is in the steady state, the air-conditioning enjoyment time obtained by integrating the time existing in the air-conditioned space is calculated for each resident (step S25).

  The air conditioning evaluation target extraction unit 324 compares the operation cycle calculated by the operation cycle calculation unit 321 with the air conditioning enjoyment time of each resident calculated by the stay time calculation unit 323, and the operation cycle <air conditioning enjoyment time, that is, Residents whose air-conditioning enjoyment time is longer than the operation cycle are extracted as air-conditioning evaluation targets (step S26).

  The stay time calculation unit 323 calculates, for each resident, the continuous stay time, which is the time that the resident of the air conditioning evaluation target extracted by the air conditioning evaluation target extraction unit 324 has continuously stayed in the air conditioned space. (Step S27). The stay time calculation unit 323 may treat the absence of seats within a specified period, for example, 5 minutes or less as a continuous condition. Thereby, the stay time calculation part 323 can calculate a continuous stay time appropriately by excluding the seat leaving in the range which is not influenced by another air-conditioned space or outside air.

  The occupant comfort totaling unit 325 refers to the first air conditioning evaluation value of the air conditioning evaluation target resident extracted by the air conditioning evaluation target extracting unit 324, and according to the continuous stay time calculated by the stay time calculating unit 323. The first air conditioning evaluation value is corrected (step S28). The occupant comfort totaling unit 325 gives the occupant's thermal sensation that the continuous stay period in the conditioned space is shorter than the third period to the first air conditioning evaluation value, that is, the thermal sensation. If the air conditioning control is heating, correct it to a cold or uncomfortable direction. Specifically, if the continuous stay time is shorter than a third period, for example, 30 minutes, the occupant comfort totaling unit 325 corrects the occupant comfort totaling unit 325 to be colder than the input thermal sensation. For example, when the thermal sensation is evaluated in seven stages, the occupant comfort totaling unit 325 corrects one stage by a seven-stage evaluation to the cold side. The third period is an example and is not limited to 30 minutes. Further, the third period may be a time different between the cooling period and the heating period.

  The occupant comfort totaling unit 325 calculates and outputs the corrected average value of the first air conditioning evaluation values of the air conditioning evaluation target residents as the air conditioning evaluation value of the entire air conditioning space, that is, the second air conditioning evaluation value. (Step S29). The occupant comfort totaling unit 325 calculates the corrected first air conditioning evaluation value, that is, the average value of thermal sensation as the second air conditioning evaluation value, but is not limited to this, and the corrected first air conditioning evaluation value. The air conditioning evaluation value, that is, a value obtained by a statistical method such as the median value or the mode value of thermal sensation may be calculated as the second air conditioning evaluation value.

  In addition, when the steady state determination unit 322 determines that the current air conditioning control state is not the steady state (step S22: No), the second air conditioning evaluation value is not calculated, and the second air conditioning evaluation value is absent. It outputs to the air-conditioning control adjustment part 31 (step S30). The case of Step S22: Yes corresponds to the case of Step S6: Yes in the flowchart of FIG. 3, and the case of Step S22: No and Step S30 corresponds to the case of Step S6: No in the flowchart of FIG.

  Here, the hardware configuration of the air conditioning control device 3 will be described. The function of communicating with the air conditioner 1 in the air conditioning control adjustment unit 31 and the air conditioning operation acquisition unit 33 is realized by an interface circuit. The function of communicating with the position measurement device 4 in the resident position calculation unit 34 is realized by an interface circuit. The other functions of the air conditioning control adjustment unit 31, the air conditioning operation acquisition unit 33, the occupant position calculation unit 34, and the function of the air conditioning evaluation calculation unit 32 are realized by a processing circuit. The processing circuit may be dedicated hardware, or a CPU (Central Processing Unit) that executes a program stored in the memory and a memory.

  When the processing circuit is dedicated hardware, the processing circuit is, for example, a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, an ASIC (Application Specific Integrated Circuit), or an FPGA (Field Programmable Gate Array). Or a combination of these.

  When the processing circuit includes a CPU and a memory, each function of the air conditioning control device 3 is realized by software, firmware, or a combination of software and firmware. Software or firmware is described as a program and stored in a memory. In the processing circuit, each function is realized by the CPU reading and executing the program stored in the memory. Here, the CPU may be a processing device, an arithmetic device, a microprocessor, a microcomputer, a processor, a DSP (Digital Signal Processor), or the like. The memory is a nonvolatile or volatile semiconductor such as a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an EPROM (Erasable Programmable ROM), or an EEPROM (registered trademark) (Electrically EPROM). A memory, a magnetic disk, a flexible disk, an optical disk, a compact disk, a mini disk, a DVD (Digital Versatile Disc), or the like is applicable.

  About each function of the air-conditioning control apparatus 3, you may make it implement | achieve part by exclusive hardware and implement | achieve part by software or firmware. As described above, the processing circuit can realize the above-described functions by dedicated hardware, software, firmware, or a combination thereof.

  As described above, according to the present embodiment, the air conditioning control device 3 adjusts the content of the air conditioning control of the air conditioner 1 using the resident's evaluation of the air conditioning control being executed. Thereby, the air-conditioning control apparatus 3 can improve the comfort of the air-conditioning space which the air conditioner 1 of the air-conditioning control system 10 makes the object of air-conditioning control.

  Moreover, the air-conditioning control apparatus 3 adjusts the next air-conditioning control using the evaluation of the resident who fully enjoyed the air-conditioning effect of the air-conditioning control after the change with respect to the change of the air-conditioning control accompanying the adjustment of the air-conditioning control. Thereby, the air-conditioning control apparatus 3 can adjust the content of the air-conditioning control of the air conditioner 1 appropriately. Further, the air conditioning control device 3 can adjust the content of the air conditioning control based on the correct evaluation with respect to the air conditioner 1 having a constant operation cycle, that is, a fluctuation cycle. In addition, the air conditioning control device 3 can adjust the content of the air conditioning control based on the correct evaluation with respect to the air conditioner 1 even when the content of the air conditioning control is largely changed.

  Moreover, the air-conditioning control apparatus 3 can adjust the content of the air-conditioning control in consideration of the point that the occupant feels different thermal sensation compared to the case where the resident stays for a long time immediately after entering from the outside. Moreover, the air-conditioning control apparatus 3 can adjust the content of the air-conditioning control of the air conditioner 1 excluding the tendency that the resident's evaluation shifts to the hot side during heating and cooling, and the resident stays for a long time. A comfortable air-conditioned space can be formed. In addition, the tendency of residents' evaluation to shift to the hot side during heating and cooling is cool in summer due to the temperature difference immediately after entering and exiting, but the sweater quickly sweats and the resident's body temperature decreases and shifts to the hot side. In winter, the temperature difference immediately after entering and exiting makes it warmer and continues until the occupant's body cools down.

  In addition, although this Embodiment demonstrated the operation | movement in which the air-conditioning evaluation object extraction part 324 extracts a part of resident, it is not limited to this. For example, the air conditioning evaluation target extraction unit 324 gives a large weight to the residents corresponding to the extraction, and gives a small weight to the other residents, and the resident comfort totalization unit 325 gives the air conditioning evaluation target extraction unit 324. The air conditioning evaluation value may be calculated as a weighted average according to the weights. Thereby, the air-conditioning control apparatus 3 can consider the evaluation of the resident who does not correspond to the extraction standard at a certain ratio.

  Moreover, although the case where the air-conditioning control apparatus 3 performed determination of a steady state, determination of an operation period, etc. was demonstrated each time, it is not limited to this. The air conditioning control device 3 may be provided with a table indicating a correspondence relationship between the determination material and the determination result, and may perform each determination process, or may correct the table according to the results of the determination process.

  Further, the resident position calculation unit 34 may use the measurement result of the reception intensity of the beacon radio wave of the mobile terminal 2 as a method for calculating the resident position, and is operated when the position of the personal computer is known. The position of the resident may be specified by detecting a personal computer, or the position of the resident may be specified using a seat sensor.

Embodiment 2. FIG.
In Embodiment 2, instead of the suction temperature of the air conditioner 1, the room temperature around the occupant is used. A different part from Embodiment 1 is demonstrated.

  FIG. 6 is a diagram illustrating a configuration example of an air conditioning control system 10a according to the second embodiment. In the air conditioning control system 10a, the air conditioning control device 3 is deleted from the air conditioning control system 10 according to the first embodiment shown in FIG. 1, and an air conditioning control device 3a and environmental sensors 5-1 and 5-2 are added. The environmental sensors 5-1 and 5-2 are connected to the air conditioning control device 3a by wireless communication. The environmental sensors 5-1 and 5-2 are temperature / humidity sensors that are installed around the occupant's seat in the air-conditioned space and measure the temperature and humidity around the occupant. The environmental sensors 5-1 and 5-2 do not measure both temperature and humidity, and may measure at least one of temperature and humidity. In the following description, when the environmental sensors 5-1 and 5-2 are not distinguished, they are referred to as environmental sensors 5.

  FIG. 7 is a block diagram illustrating a configuration example of the air conditioning control device 3a according to the second embodiment. The air-conditioning control device 3a is obtained by deleting the air-conditioning evaluation calculation unit 32 and the air-conditioning operation acquisition unit 33 from the air-conditioning control device 3 according to the first embodiment shown in FIG. 2 and adding an air-conditioning evaluation calculation unit 32a and an environment measurement unit 35. is there. The air conditioning evaluation calculation unit 32a calculates an evaluation value of the comfort of the resident in the air conditioned space. The environment measurement unit 35 acquires the temperature and humidity around the occupant measured by the environment sensor 5.

  The configuration of the air conditioning evaluation calculation unit 32a will be described. The air conditioning evaluation calculation unit 32a includes an operation cycle calculation unit 321a, a steady state determination unit 322a, a stay time calculation unit 323, an air conditioning evaluation target extraction unit 324, and a resident comfort totalization unit 325a.

  The operation cycle calculation unit 321 a calculates the indoor temperature fluctuation cycle, that is, the operation cycle of the air conditioner 1, using the room temperature acquired from the environment measurement unit 35. Unlike the operation cycle calculation unit 321, the operation cycle calculation unit 321a uses the indoor temperature instead of the suction temperature. However, the operation cycle calculation method is the same as that of the operation cycle calculation unit 321.

  The steady state determination unit 322a uses the room temperature acquired from the environment measurement unit 35 to determine whether the steady state has been entered. Unlike the steady state determination unit 322, the steady state determination unit 322a uses the indoor temperature instead of the suction temperature. However, the steady state determination method is the same as that of the steady state determination unit 322.

  The occupant comfort totalization unit 325a estimates the first air conditioning evaluation value that is the thermal sensation of the extracted occupants, totals the estimated first air conditioning evaluation value, and controls the air conditioning control of the air conditioner 1. A second air conditioning evaluation value used in determining the content is calculated. In other words, the occupant comfort totaling unit 325a estimates the first air conditioning evaluation value, and calculates the second air conditioning evaluation value using the estimated first air conditioning evaluation value.

  It continues and demonstrates operation | movement of the air-conditioning control apparatus 3a. FIG. 8 is a flowchart showing the operation of the air conditioning control device 3a according to the second embodiment.

  The operation of the resident position calculation unit 34 in steps S1 and S2 is the same as the operation in the first embodiment. The environment measuring unit 35 acquires the temperature around the occupant, that is, the room temperature, from the environment sensor 5 (step S11). In the following description, the case where the air conditioning control device 3a uses the room temperature is described as an example, and the humidity around the occupant measured by the environmental sensor 5, that is, the room humidity may be used. Both temperature and room humidity may be used.

  The air conditioning evaluation calculation unit 32a estimates a first air conditioning evaluation value that is a thermal sensation of the occupant, and uses the indoor temperature history, the resident location history, and the resident first air conditioning evaluation value, A process of calculating an air conditioning evaluation value indicating the thermal sensation of the entire air conditioning space that is the air conditioning control target of the air conditioning control system 10a, that is, a second air conditioning evaluation value is performed (step S12). Note that the air conditioning evaluation calculation unit 32a may not calculate the second air conditioning evaluation value, such as when the air conditioning control adjustment unit 31 is not in a steady state immediately after changing the content of the air conditioning control. The detailed operation of step S12 in the air conditioning evaluation calculation unit 32a will be described later.

  The operation from step S6 to step S10 in the air conditioning control adjustment unit 31 is the same as the operation in the first embodiment. The air conditioning control device 3a repeatedly executes the processing of the flowchart shown in FIG. 8 at specified time intervals.

  Next, the operation of step S12 in the air conditioning evaluation calculation unit 32a will be described in detail. FIG. 9 is a flowchart showing the operation of the air conditioning evaluation calculation unit 32a according to the second embodiment.

  The steady state determination unit 322a refers to the indoor temperature history and determines whether or not the current air conditioning control state is a steady state (step S41). As described above, the determination method of the steady state determination unit 322a is the same as the determination method of the steady state determination unit 322 except that the room temperature is used. When the current air conditioning control state is determined to be the steady state (step S22: Yes), the steady state determination unit 322a notifies the operation cycle calculation unit 321a that the current air conditioning control state is the steady state.

  The operation cycle calculation unit 321a refers to the history of the room temperature, searches for a place where the room temperature periodically changes within a specified period, and calculates the change cycle as the operation cycle (step S42). As described above, the calculation method of the operation cycle calculation unit 321a is the same as the calculation method of the operation cycle calculation unit 321 except that the room temperature is used.

  The processing from step S24 to step S27 is the same as in the first embodiment.

  First, the occupant comfort counting unit 325a uses the history of the location information of the occupant to be air-conditioning evaluation extracted by the air-conditioning evaluation target extraction unit 324 and the history of the indoor temperature acquired by the environment measurement unit 35. The history of the ambient temperature of the occupants who are subject to air conditioning evaluation is calculated. The occupant comfort totaling unit 325a calculates an average ambient temperature obtained by averaging the ambient temperature for each driving cycle calculated by the driving cycle calculating unit 321a, using the calculated ambient temperature history. Then, the occupant comfort counting unit 325a estimates the thermal sensation of the occupants who are subject to air conditioning evaluation, that is, the first air conditioning evaluation value, from the calculated average ambient temperature (step S43).

  The occupant comfort totaling unit 325a uses, for example, a calculation formula such as a PMV (Predicted Mean Vote) index to set a part of parameters such as an activity amount and a clothing amount as a general value in a controlled air-conditioned space. Can be calculated as The general value in the air-conditioned space to be controlled is, for example, a standard value on the office floor. As described above, the occupant comfort totaling unit 325a estimates the occupant's first air conditioning evaluation value using the average value of the temperatures in the second period. The occupant comfort counting unit 325a may use humidity instead of temperature as described above, or may use both temperature and humidity.

  Further, the occupant comfort totaling unit 325a corrects the first air conditioning evaluation value according to the continuous stay time calculated by the stay time calculating unit 323 (step S44). The occupant comfort totaling unit 325a uses the air conditioning control for the estimated first air conditioning evaluation value, that is, the thermal sensation, for the occupant's thermal sensation in which the stay period in the air conditioned space is shorter than the third period. If the air conditioning control is heating, the warming or uncomfortable direction is corrected. Specifically, if the continuous stay time is shorter than a third period, for example, 30 minutes, the occupant comfort counting unit 325a corrects the occupant comfort totaling unit 325a to a hotter side than the estimated thermal sensation. For example, when the thermal sensation is evaluated in seven stages, the occupant comfort totaling unit 325a corrects one stage in the seven-stage evaluation to the hot side. The third period is an example and is not limited to 30 minutes. Further, the third period may be a time different between the cooling period and the heating period.

  The processing of step S29 and step S30 in the case of step S22: No is the same as in the first embodiment.

  The hardware configuration of the air conditioning control device 3a is the same as the hardware configuration of the air conditioning control device 3 of the first embodiment.

  As described above, according to the present embodiment, the air conditioning control device 3a estimates the occupant's evaluation for the air conditioning control being executed, and the air conditioning currently being executed is the same as the air conditioning control device 3 of the first embodiment. The content of the air conditioning control of the air conditioner 1 was adjusted using the resident's evaluation for the control. Thereby, the air-conditioning control apparatus 3a can improve the comfort of the air-conditioned space which the air conditioner 1 of the air-conditioning control system 10a makes the object of air-conditioning control.

  In addition, when the air conditioning control device 3a performs air conditioning control with a fixed operation cycle, the evaluation during the operation cycle prevents the evaluation from being shifted, and appropriately adjusts the content of the air conditioning control. Can do. In particular, when the time after switching the content of the air conditioning control is short and only several times of the operation cycle has elapsed, the influence of mixing in the middle of the operation cycle becomes large, so the air conditioning of the air conditioning control device 3a The effect obtained by the control is great.

  In addition, the air conditioning control device 3a can perform control adjustment in consideration of the point that the occupant feels a different feeling of warmth compared to the case where the resident stays for a long time immediately after entering from the outside. In addition, the air conditioning control device 3a can adjust the content of the air conditioning control of the air conditioner 1 by excluding the tendency that the resident's evaluation shifts to the hot side during heating and cooling.

  In the present embodiment, the occupant comfort counting unit 325a calculates an average ambient temperature obtained by averaging the ambient temperature for each operation cycle in the process of step S43, and the occupant for air conditioning evaluation from the average ambient temperature. However, the present invention is not limited to this. The occupant comfort totaling unit 325a may calculate the minimum ambient temperature that is the minimum value of the ambient temperature for each driving cycle, and estimate the thermal sensation of the occupant subject to air conditioning evaluation from the minimum ambient temperature. That is, the occupant comfort totaling unit 325a estimates the resident's first air conditioning evaluation value using at least one worst value of temperature or humidity in the second period. Thereby, the air-conditioning control device 3a can appropriately adjust the contents of the air-conditioning control by considering the evaluation at the worst value at which dissatisfaction is likely to occur when the air-conditioning control having a constant control cycle is executed. it can. For example, in the case of a system configuration in which a plurality of indoor units are connected to one outdoor unit, in the energy saving control in which each indoor unit is stopped for a certain period of time, the degree of temperature change during stoppage varies depending on the magnitude of the internal load. That is, when the internal load is large, the environment of the air-conditioned space deteriorates rapidly. The internal load is, for example, a resident in the air-conditioned space, and the internal load is large when there are many resident in the air-conditioned space. The air conditioning control device 3a can adjust the content of the air conditioning control by correctly reflecting the characteristics of each air conditioning space by considering the evaluation at the worst value.

  The configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention. It is also possible to omit or change the part.
