[0111] (Seventh Embodiment)

[0112] Figure 9 is a block diagram illustrating the thermal sensation distribution display device 700 of the seventh embodiment.

[0113] The functional configuration illustrated in Figure 9 includes a server 200, an administrator terminal 100, and a user terminal 110.

[0121] (Example 1)

[0122] Figure 10 shows the apparatus configuration of Embodiment 1 according to the first embodiment.

[0123] A portable thermal sensation acquisition terminal device 400 is provided on the user U11's side. A user body-side sensor unit 411 is positioned close to the user U11's body, for example, in a breast pocket. The user body-side sensor unit 411 detects the user's body temperature and humidity at a point close to the user U11's body. A desktop-side sensor unit 412 is positioned on the desk DK11 where the user U11 works. The desktop-side sensor unit 412 detects the desktop temperature, desktop humidity, and desktop illuminance of the work environment (task area) where the user U11 works. Depending on the temperature and humidity detection results, information on a desk with a comfortable thermal environment may be provided. Depending on the illuminance detection results, advice such as using an individual stand may be provided if the illuminance is insufficient.

[0124] The user body-side sensor unit 411 and the desktop-side sensor unit 412, and the receiver 413 of the thermal sensation acquisition terminal device 400 are wirelessly connected by a wireless communication standard such as Bluetooth®. The receiver 413 constitutes the thermal environment state quantity acquisition unit 410.

[0125] The user body temperature and user body humidity data detected by the user body-side sensor unit 411, and the desktop temperature, desktop humidity, and desktop illuminance data detected by the desktop-side sensor unit 412 are received wirelessly by the receiver 413 of the thermal sensation acquisition terminal device 400 and taken up by the thermal sensation acquisition terminal device 400. The user body temperature and user body humidity, as well as the desktop temperature and desktop humidity, are acquired sequentially at predetermined intervals and taken up sequentially by the thermal sensation acquisition terminal device 400.

[0126] Note that user body temperature and user body humidity, as well as desktop temperature and desktop humidity, are examples of thermal environment state quantities acquired by the thermal environment state quantity acquisition unit 410. The thermal environment state quantities acquired by the thermal environment state quantity acquisition unit 410 may also include the airflow generated by the air conditioning (cooling) fan 1111 of the user-side individual air conditioning equipment 1100, for example, the air conditioning (cooling) fan 1111 of the air-conditioned clothing 1110.

[0127] Figure 11 shows the transitions of the display screen 401 of the thermal sensation acquisition terminal device 400.

[0128] The thermal sensation acquisition terminal device 400 either has a thermal sensation acquisition program installed or can download it from the server 200 via the network 300.

[0129] When the thermal sensation acquisition program is activated, the processes shown in Figure 11 are executed sequentially.

[0130] At the beginning of the day, for example at the start of work, the workload selection screen 431 is displayed on the display screen 401. The workload selection screen 431 includes selection sections 431A, 431B, 431C, and 431D that indicate the current workload, such as "desk work (desk work with little movement)", "desk work with a lot of movement (desk work involving movement)", "assembly work in a standing position", and "work involving the transport of goods, etc.". When one of the selection sections 431A, 431B, 431C, and 431D is selected on the workload selection screen 431, the display screen 401 transitions to the clothing amount selection screen 432.

[0131] The clothing amount selection screen 432 includes selection sections 432A, 432B, 432C, 432D, and 432E that indicate the current amount of clothing worn, such as "short sleeves," "short sleeves + vest," "short sleeves + long-sleeved work clothes, etc.," "long-sleeved shirt," and "long-sleeved shirt + long-sleeved work clothes, etc." When one of the selection sections 432A, 432B, 432C, 432D, and 432E is selected on the clothing amount selection screen 432, the display screen 401 transitions to the thermal sensation selection screen 421.

[0132] The temperature selection screen 421 includes selection sections 421A, 421B, 421C, 421D, 421E, 421F, and 421G that indicate the current temperature, such as "hot," "warm," "slightly warm," "neutral," "slightly cool," "cool," and "cold." Each of these selection sections 421A, 421B, 421C, 421D, 421E, 421F, and 421G is associated with an icon 421AI, 421BI, 421CI, 421DI, 421EI, 421FI, and 421GI, respectively, that indicates the current temperature.

[0133] When one of the selection units 421A, 421B, 421C, 421D, 421E, 421F, or 421G is selected on the thermal sensation selection screen 421, the display screen 401 transitions to the thermal sensation survey results screen 422.

[0134] The thermal sensation survey results screen 422 displays the selection of the selection section that was selected on the thermal sensation selection screen 421 that was displayed immediately before, for example, the selection of selection section 421C, "slightly warm," along with the icon 421CI.

[0135] If the user presses the "Retry Answer" button 422A on the thermal sensation survey results screen 422, the display screen 401 transitions to the thermal sensation selection screen 421 that was displayed immediately before. The user can then retake their thermal sensation questions on the thermal sensation selection screen 421.

[0136] When the confirmation button (not shown) is pressed on the thermal sensation survey results screen 422, or after a predetermined time has elapsed, the selection made on the thermal sensation selection screen 421 is confirmed, and the display screen 401 transitions to the home screen 402.

[0137] Thereafter, at predetermined regular intervals, for example every hour, a display unit 402A prompting the user to display the temperature selection screen 401 will pop up on the display screen 401. When the user presses the button 402B on the display unit 402A, the display screen 401 transitions to the temperature selection screen 421. This allows the user to respond to the temperature selection question at predetermined regular intervals, for example every hour. Alternatively, the display screen 401 may be forcibly transitioned to the temperature selection screen 421 at predetermined regular intervals, for example every hour, to periodically prompt the user to respond to the temperature selection question. The interval for responding to the temperature selection question can be set arbitrarily. The interval for responding to the temperature selection question may also be irregular. For example, an irregular period during which the user U11 can respond may be set according to the user's work environment, and each time that period arrives, the display unit 402A prompting the user to respond to the temperature selection question may be displayed on the display screen 401, or the display screen 401 may be automatically transitioned to the temperature selection screen 421.

[0138] Alternatively, instead of users selecting their workload, clothing load, and temperature perception, they can also provide these values ​​as text input.

[0139] When data collection for the day ends, for example, at the end of the workday, the display screen 401 transitions to the user's surrounding environment comfort level screen 441.

[0140] The user environment comfort screen 441 displays the user environment comfort level P1 corresponding to the thermal environment state quantity (e.g., desktop temperature) TM and the thermal / cold sensation TF. The user environment comfort level P1 is displayed in association with the average value of the thermal environment state quantity (e.g., desktop temperature) TM acquired sequentially throughout the day and the average value of the thermal / cold sensation TF selected at predetermined periodic or irregular intervals.

[0141] Figures 12A, 12B, and 12C illustrate examples of the content displayed on the user's surrounding environment comfort level screen 441.

[0142] As shown in Figures 12A, 12B, and 12C, the user ambient comfort level screen 441 displays the user ambient comfort level P1, icons Z1I, Z2I, and Z3I indicating the user ambient comfort level P1, and a comment C1 corresponding to the user ambient comfort level P1. The comment C1 is automatically generated by adding the set temperature information of the overall air conditioning equipment 1000 to the user ambient comfort level P1 information.

[0143] The user's ambient environment comfort level P1 is represented by points plotted on a coordinate plane with the thermal environment state variable (e.g., desktop temperature) TM on the horizontal axis and the thermal / cold sensation TF on the vertical axis. The thermal / cold sensation TF is quantified as follows: "hot," "warm," "somewhat warm," "neutral," "somewhat cool," "cool," and "cold," with values ​​of 3, 2, 1, 0, -1, -2, and -3, respectively.

[0144] The comfort level of the user's surrounding environment P1 is evaluated based on whether it belongs to a first region Z1 located at a predetermined distance from the origin, a second region Z2 located beyond the first region Z1, or a third region Z3 located beyond the second region Z2.

[0145] As shown in Figure 12A, if the user's surrounding environment comfort level P1 belongs to the first region Z1, the user's surrounding environment comfort level P1 is evaluated as "comfortable". The first region Z1 is associated with the icon Z1I, which indicates "comfortable". The content of comment C1 is, for example, "Today's desk surrounding environment evaluation is a smiley face. The average desktop temperature is 25.4℃. The feeling of heat and cold at the average temperature is almost neutral. It is close to the air conditioner setting temperature of 26℃, so I feel it is neutral and have given it a smiley face."

[0146] As shown in Figure 12B, if the user environment comfort level P1 belongs to the second region Z2, the user environment comfort level P1 is evaluated as "somewhat uncomfortable". The icon Z2I, which indicates "somewhat uncomfortable", is associated with the second region Z2. The content of comment C1 is, for example, "Today's desk environment evaluation is not great. The average desktop temperature is 24.6℃. The feeling of warmth at the average temperature is warm. It is close to the air conditioner setting temperature of 26℃, but I feel warm, so I gave it a not-so-great mark."

[0147] As shown in Figure 12C, if the user's surrounding environment comfort level P1 belongs to the third region Z3, the user's surrounding environment comfort level P1 is evaluated as "uncomfortable". The third region Z3 is associated with the icon Z3I, which indicates "uncomfortable". The content of comment C1 is, for example, "Today's desk environment evaluation is an irritation mark. The average desktop temperature is 23.4℃. The feeling of warmth or coolness at the average temperature is considerably lower than the slightly cool air conditioner setting of 26℃, so it feels slightly cool, hence the irritation mark."

[0148] According to Example 1, the user can easily obtain the data necessary to display maps of the distribution of expected discomfort and the distribution of thermal sensation.

[0149] Furthermore, according to Example 1, users can easily recognize the level of comfort in their desk environment.

[0150] (Example 2)

[0151] The following describes Example 2 according to the second, third, fourth, fifth, and sixth embodiments.

[0152] Figure 13 shows a floor plan of a factory where a total air conditioning unit 1000 is installed in various locations. Areas AR1 to AR17 each represent user areas where one or more users perform work.

[0153] User area AR1 is the area where logistics-related work is performed, and it is an area where the overall air conditioning unit 1000 is not installed.

[0154] User area AR2 is the area where logistics-related work is performed, and it is an area where the overall air conditioning unit 1000 is not installed.

[0155] User area AR3 is the area where logistics-related work is performed, and it is an area where the overall air conditioning unit 1000 is not installed.

[0156] User area AR4 is the area where operations related to the receiving and dispatching of materials in the warehouse are performed, and it is an area where the overall air conditioning unit 1000 is not installed.

[0157] User area AR5 is the area where operations related to the receiving and dispatching of materials in the warehouse are performed, and it is an area where the overall air conditioning unit 1000 is not installed.

[0158] User area AR6 is the area where molding-related work is performed, and it is the area where the overall air conditioning unit 1000 is installed.

[0159] User area AR7 is the area where molding-related work is performed, and it is the area where the overall air conditioning unit 1000 is installed.

[0160] User area AR8 is the area where assembly work is performed and where the overall air conditioning unit 1000 is installed.

[0161] User area AR9 is the area where assembly work is performed and where the overall air conditioning unit 1000 is installed.

[0162] User area AR10 is the area where assembly work is performed and where the overall air conditioning equipment 1000 is installed.

[0163] User area AR11 is the area where assembly work is performed and where the overall air conditioning unit 1000 is installed.

[0164] User area AR12 is the area where subsequent work is performed and where the overall air conditioning equipment 1000 is installed.

[0165] User area AR13 is the area where weighing-related work is performed, and it is the area where the overall air conditioning equipment 1000 is installed.

[0166] User area AR14 is the area where quality-related work is performed and is the area where the overall air conditioning equipment 1000 is installed.

[0167] User area AR15 is the area where quality-related work is performed and is the area where the overall air conditioning equipment 1000 is installed.

[0168] User area AR16 is the area where inspection-related work is performed, and it is the area where the overall air conditioning unit 1000 is installed.

[0169] User area AR17 is the area where office work is performed and where the overall air conditioning unit 1000 is installed.

[0170] Returning to Figure 10, user U11 is provided with a user-side individual air conditioning unit 1100.

[0171] The user-side individual air conditioning device 1100 is, for example, an air-conditioned garment 1110 worn by user U11. The air-conditioned garment 1110 has a built-in air conditioning (cooling) fan 1111, and when the air conditioning (cooling) fan 1111 is driven, an airflow is generated on the surface of user U11's body, cooling the surface of user U11's body. Any device that provides personal air conditioning can be used as the user-side individual air conditioning device 1100. For example, a desktop fan that provides a cooling sensation to the user, or a heated vest or heated blanket that provides a warming sensation to the user can be used as the user-side individual air conditioning device 1100.

[0172] The airflow velocity generated by the cooling fan 1111 of the air-conditioned garment 1110 can be adjusted by manual operation or automatic control. For example, a suggested value for the airflow velocity is displayed on the display screen 401 of the thermal sensation acquisition terminal device 400. User U11 can manually adjust the airflow velocity generated by the cooling fan 1111 of the air-conditioned garment 1110 according to the suggested value for the airflow velocity displayed on the display screen 401 of the cooling sensation acquisition terminal device 400. Alternatively, the airflow velocity generated by the cooling fan 1111 of the air-conditioned garment 1110 can be automatically adjusted according to the control signal output from the thermal sensation acquisition terminal device 400.

[0173] (Display of predicted discomfort distribution)

[0174] Figure 14A illustrates the predicted discomfort distribution display screen 800A shown on the display screen 17A of the display device 17 of the administrator terminal 100.

[0175] The predicted discomfort distribution display screen 800A includes a predicted discomfort map display unit 801 and a predicted discomfort ratio display unit 802.

[0176] The expected discomfort map display unit 801 displays the expected discomfort level for each user area AR1 to AR17, using a different hue for each level. The expected discomfort map display unit 801 only needs to display the expected discomfort level for each user area AR1 to AR17 in a manner that allows identification by at least one of hue, saturation, or brightness. For example, if the expected discomfort level is "uncomfortable," the corresponding user area is displayed in "red" (shown as solid black in the figure). If the expected discomfort level is "somewhat uncomfortable," the corresponding user area is displayed in "orange" (shown as cross-hatching in the figure). If the expected discomfort level is "mostly comfortable," the corresponding user area is displayed in "orange" (shown as hatching in the figure). If the expected discomfort level is "quite comfortable," the corresponding user area is displayed in "blue" (shown as halftones in the figure).

[0177] The expected discomfort ratio display unit 802 shows, in pie chart form, the percentage of users with each expected discomfort level ("uncomfortable," "somewhat uncomfortable," "mostly comfortable," and "quite comfortable") relative to the total number of users in user areas AR1 to AR17.

[0178] Here, expected discomfort is an indicator that represents user comfort, such as the PPD (Predicted Percentage of Dissatisfied) index.

[0179] PPD can be calculated using an index called PMV (Predicted Mean Vote).

[0180] PMV, like PPD, is an index that represents user comfort and can be calculated based on the user's workload, amount of clothing worn, temperature, humidity, airflow velocity, etc., acquired by the cooling sensation acquisition terminal device 400. Airflow velocity is determined as the speed of the airflow generated by the cooling fan of the user-side individual air conditioning device 1100 (air-conditioned clothing 1110).

[0181] The user's workload, clothing load, user body temperature, desktop temperature, user body humidity, desktop humidity, and airflow velocity, acquired by the thermal sensation acquisition terminal device 400, are stored in the database 210 of the server 200 via the network 300.

[0182] Server 200 calculates metabolic rate M, mechanical work W, insensible perspiration Ed, evaporative heat loss E due to sweating, latent heat loss E due to respiration, sensible heat loss Cre due to respiration, radiant heat loss R, and convective heat loss C, based on the user's workload, clothing weight, user body temperature, desktop temperature, user body humidity, desktop humidity, and airflow velocity obtained from each user, in order to calculate PMV.

[0183] The calculated metabolic rate M, mechanical work W, insensible water loss Ed, evaporative heat loss E due to sweating, latent heat loss Ere due to respiration, sensible heat loss Cre due to respiration, radiant heat loss R, and convective heat loss C are substituted into Fanger's equation shown in equation (1) below to calculate the PMV value.

[0184] PMV value={0.303exp(-0.036M)+0.028}×{(MW)-Ed-Es-Ere-Cre-RC}···(1)

[0185] PPD (%) can be calculated using the PMV value from the following formula (2). Note that "^" means exponentiation.

[0186] PPD=100-95exp((-(0.03353·PMV^4+0.2179·PMV^2))···(2)

[0187] The method for calculating the PPD value described above is just one example; the PPD value may also be determined using fewer thermal environment conditions and a simpler calculation formula. Alternatively, the thermal environment conditions and PPD values ​​may be stored in association with each other, and the PPD value corresponding to the acquired thermal environment conditions may be read out.

[0188] The PPD value is an indicator that shows the percentage of people who feel thermally dissatisfied with their environment. When the PMV value is "0", the PPD takes its lowest value of 5% (maximum thermal satisfaction). The PPD (%) ranges from 0 to 100% and is divided into different levels of expected discomfort, with each of these levels of expected discomfort corresponding to "very comfortable," "almost comfortable," "somewhat uncomfortable," and "uncomfortable." For example, the average PPD value of all users belonging to the user area AR is calculated, and the level of expected discomfort to which this average PPD value of all users belongs (e.g., "almost comfortable") is determined to be the level of expected discomfort in that user area AR.

[0189] On server 200, a predicted discomfort distribution display screen 800A is generated based on the results of the above calculation process, and the predicted discomfort distribution display screen 800A is stored in an accessible location.

[0190] The administrator can access the server 200 via the administrator terminal 110 and request the display of the predicted discomfort distribution screen 800A, thereby causing the display screen 17A of the display device 17 of the administrator terminal 110 to display the predicted discomfort distribution screen 800A shown in Figure 14A.

[0191] As shown in Figure 14A, the predicted discomfort map display section 801 of the predicted discomfort distribution display screen 800A displays the current predicted discomfort level in the corresponding hue, corresponding to each of the user areas AR1 to AR17.

[0192] As shown in Figure 14A, the predicted discomfort map display section 801 of the predicted discomfort distribution display screen 800A displays the current set temperatures T1 to T17 of the overall air conditioning unit 1000, corresponding to each of the user areas AR1 to AR17. In user areas AR1, AR2, AR3, AR4, and AR5 where the overall air conditioning unit 1000 is not installed, the set temperatures T1, T2, T3, T4, and T5 are displayed as "None". In user areas AR6, AR7, AR8, AR9, AR10, AR11, AR12, AR13, AR14, AR15, AR16, and AR17, where the 1000-unit air conditioning unit is installed, the set temperatures T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, and T17 are displayed as 26, 25, 27, 24, 24, 24, 23, 20, 22, 22, 24, and 25 (°C), respectively.

[0193] For example, it can be predicted that users in user areas AR1, AR2, AR3, AR4, and AR5 of the logistics and material warehouses, where the overall air conditioning unit 1000 is not installed, and users in user areas AR6 and AR7 of the molding area, where the overall air conditioning unit 1000 is installed but the machinery generates heat, are currently experiencing high levels of discomfort ("uncomfortable"). Additionally, it can be predicted that users in user area AR8 of the assembly area, where the temperature setting of the overall air conditioning unit 1000 is set to the highest setting of 27°C, are currently experiencing "somewhat uncomfortable".

[0194] As shown in Figure 14A, the predicted discomfort distribution display screen 800A's predicted discomfort ratio display unit 802 displays the current number of users for each predicted discomfort level ("uncomfortable," "somewhat uncomfortable," "mostly comfortable," and "quite comfortable") relative to the total number of users in user areas AR1 to AR17. It can be predicted that the ratio of users who currently feel "uncomfortable" relative to the total number of users is 32%, and the ratio of users who currently feel "somewhat uncomfortable" is 11%.

[0195] (Virtual setting change of the set temperature of the central air conditioning unit 1000, acquisition of suggested values ​​for the airflow velocity of the user-side individual air conditioning unit 1100)

[0196] Therefore, we will conduct simulations to improve the level of discomfort in user regions AR1, AR2, AR3, AR4, AR5, AR6, AR7, and AR8, where the level of discomfort is rated as "unpleasant" or "somewhat unpleasant."

[0197] Figure 14B illustrates the predicted discomfort distribution display screen 800B after implementing measures to improve the predicted discomfort level (referred to as a simulation of implementing the measures).

[0198] The implementation simulation of countermeasures can be carried out, for example, according to the following conditions:

[0199] Condition (1): In order to achieve energy saving effects, for user areas AR1 to AR8 where the level of discomfort is "uncomfortable" or "somewhat uncomfortable," the set temperature of the overall air conditioning unit 1000 will not be lowered, but the comfort level will be adjusted to "somewhat uncomfortable" or higher by adjusting the airflow velocity of the individual user air conditioning units 1100 (air-conditioned clothing 1110). If an airflow velocity of 4 m / s is added without lowering the set temperature of the overall air conditioning unit 1000 for user areas AR1 to AR8 in logistics, material warehouse, and molding, it can be predicted from the above PPD calculation formula that user areas AR1 to AR7 will improve from "uncomfortable" to "somewhat uncomfortable," and user area AR8 will improve from "somewhat uncomfortable" to "quite comfortable."

[0200] Condition (2): In order to achieve energy saving effects, the set temperature of the overall air conditioning unit 1000 will be increased for user areas AR9 to AR17 where the level of discomfort is "almost comfortable" or "quite comfortable" to bring the level of comfort to "somewhat uncomfortable" or higher. Even if the set temperature of the overall air conditioning unit 1000 for user areas AR9 to AR17, which are "almost comfortable" or "quite comfortable," is increased by 1°C, it can be predicted that the assembly user area AR10 will become "somewhat uncomfortable," but the rest of the area will maintain a level of comfort of "almost comfortable" or higher.

[0201] The setting change value (+1°C) for the central air conditioning unit 1000 is displayed corresponding to user areas AR9 to AR17.

[0202] The suggested airflow velocity (4 m / s) for the user-side individual air conditioning unit 1100 (air-conditioned clothing 1110) is displayed on the suggested airflow velocity display unit 803.

[0203] Furthermore, it is also possible to provide a suggested value for the amount of clothing the user is wearing, either together with the user-side air conditioning device 1100 (air-conditioned clothing 1110) or in place of the user-side air conditioning device 1100 (air-conditioned clothing 1110).

[0204] As shown in the predicted displeasure ratio display unit 802, after the implementation simulation of countermeasures, it is predicted that the ratio of users who feel "unpleasant" will be 0% of the total number of users, and the ratio of users who feel "somewhat uncomfortable" will be 42%.

[0205] (Set temperature of the central air conditioner 1000 and manual control of individual user-side air conditioning units 1100)

[0206] Along with or without conducting a simulation of implementing countermeasures, the airflow velocity of the user-side individual air conditioning equipment 1100 (air-conditioned clothing 1110) and the set temperature of the overall air conditioner 1000 may be manually controlled to obtain the expected distribution of discomfort shown in Figure 14B.

[0207] In accordance with condition (1), a suggested airflow velocity of 4 m / s for the user-side individual air conditioning device 1100 (air-conditioned clothing 1110) is presented to each user belonging to user areas AR1 to AR8. That is, data indicating the suggested airflow velocity of 4 m / s is transmitted from the server 200 via the network 300 to the thermal sensation acquisition terminal device 400, which serves as the user-side terminal 110 for each user belonging to user areas AR1 to AR8. The suggested airflow velocity of 4 m / s is displayed on the display screen 401 of the thermal sensation acquisition terminal device 400. In accordance with this display, if the user is not already wearing the air-conditioned clothing 1110, they can put it on and manually adjust the airflow velocity generated by the cooling fan 1111 of the air-conditioned clothing 1110 so that it reaches the suggested value of 4 m / s.

[0208] Furthermore, in accordance with condition (2), a suggested set temperature for the overall air conditioning equipment 1000 in user areas AR9 to AR17, increased by 1°C, is presented to the administrator responsible for setting the overall air conditioning equipment 1000. That is, data indicating the suggested set temperature + 1°C is transmitted from the server 200 via the network 300 to the administrator's terminal 110, which manages the overall air conditioning equipment 1000 in user areas AR9 to AR17. The display screen of the display device 17 on the administrator's terminal 110 displays the suggested set temperature + 1°C. Following this display, the administrator can adjust the set temperature of the overall air conditioning equipment 1000 in user areas AR9 to AR17 to increase the current set temperature by +1°C.

[0209] According to Example 2, it is possible to grasp the changes in the distribution of expected discomfort in the user area in response to changes in the set temperature of the overall air conditioning equipment.

[0210] Furthermore, according to Example 2, the airflow velocity and / or clothing amount of the user-side individual air conditioning equipment necessary to maintain the expected level of discomfort in the user area at an optimal level can be easily obtained in response to changes in the set temperature of the overall air conditioning equipment.

[0211] Furthermore, according to Example 2, the proposed values ​​for the airflow velocity of individual user-side air conditioning equipment and / or the amount of clothing worn, as well as the set temperature of the overall air conditioner, necessary to maintain the expected level of discomfort in the user area at an optimal level, are obtained and presented to each user and / or the manager of the overall air conditioner, thereby enabling optimal adjustment of the thermal environment for each user.

[0212] (Example 3)

[0213] The comfort level of the environment surrounding each user's desk (DK) may be maintained at an optimal level.

[0214] Returning to Figures 12A, 12B, and 12C, depending on the evaluation of "comfortable," "somewhat uncomfortable," and "uncomfortable" shown by the user's surrounding environment comfort level P1, suggested values ​​for user-side air conditioning equipment 1100 (air-conditioned clothing 1110) and suggested set temperatures for the overall air conditioner 1000 may be presented to maintain the comfort level of the surrounding environment of each user's desk DK at an optimal level.

[0215] As shown in Figure 12A, if the user's surrounding environment comfort level P1 belongs to the first area Z1, the current user's surrounding environment comfort level P1 is evaluated as "comfortable". In this case, according to condition (2), a suggested set temperature, for example, one 1°C higher than the set temperature of the overall air conditioning unit 1000 in the user area AR to which this user belongs, is presented to the administrator who sets the overall air conditioning unit 1000. That is, data indicating the suggested set temperature + 1°C is transmitted from the server 200 via the network 300 to the administrator's terminal 110 of the administrator who manages the overall air conditioning unit 1000 in the user area AR. The display screen of the display device 17 on the administrator's terminal 110 displays the suggested set temperature + 1°C. In accordance with this display, the administrator can adjust the set temperature of the overall air conditioning unit 1000 in the user area AR to be 1°C higher than the current set temperature.

[0216] As shown in Figure 12B, if the user's surrounding environment comfort level P1 belongs to the second region Z2, the current user's surrounding environment comfort level P1 is evaluated as "somewhat uncomfortable". In this case, according to condition (1), a suggested airflow velocity of 2 m / s for the user's individual air conditioning device 1100 (air-conditioned clothing 1110) is presented to the user. That is, data indicating the suggested airflow velocity of 2 m / s is transmitted from the server 200 to the user's thermal sensation acquisition terminal device 400 via the network 300. The suggested airflow velocity of 2 m / s is displayed on the display screen 401 of the thermal sensation acquisition terminal device 400. In accordance with this display, the user can wear the air-conditioned clothing 1110 if not already wearing it, and manually adjust the airflow velocity generated by the cooling fan 1111 of the air-conditioned clothing 1110 so that it reaches the suggested value of 2 m / s.

[0217] As shown in Figure 12C, if the user's surrounding environment comfort level P1 belongs to the third region Z3, the current user's surrounding environment comfort level P1 is evaluated as "uncomfortable". In this case, according to condition (1), a suggested airflow velocity of 4 m / s for the user's individual air conditioning device 1100 (air-conditioned clothing 1110) is presented to the user. That is, data indicating the suggested airflow velocity of 4 m / s is transmitted from the server 200 to the user's thermal sensation acquisition terminal device 400 via the network 300. The suggested airflow velocity of 4 m / s is displayed on the display screen 401 of the thermal sensation acquisition terminal device 400. In accordance with this display, the user can wear the air-conditioned clothing 1110 if not already wearing it, and manually adjust the airflow velocity generated by the cooling fan 1111 of the air-conditioned clothing 1110 so that it reaches the suggested value of 4 m / s.

[0218] Furthermore, it is also possible to implement this by presenting a suggested amount of clothing worn by the user, either together with the user-side air conditioning device 1100 (air-conditioned clothing 1110) or as an alternative to the user-side air conditioning device 1100 (air-conditioned clothing 1110).

[0219] According to Example 3, the proposed values ​​for the airflow velocity of individual user-side air conditioning equipment and / or the amount of clothing worn, as well as the set temperature of the overall air conditioner, necessary to maintain the comfort level of each user's desk environment at an optimal level, are obtained and presented to each user and the setting manager of the overall air conditioner, thereby enabling optimal adjustment of each user's thermal environment.

[0220] (Example 4)

[0221] In Example 2, instead of manually adjusting the set temperature of the central air conditioner 1000 and the individual air conditioning units 1100 on the user side, they may be automatically controlled.

[0222] The following explanation will omit details that overlap with those in Example 2 as appropriate.

[0223] (Automatic control of the set temperature of the central air conditioning unit 1000 and the individual air conditioning units 1100 on the user side)

[0224] Along with or without conducting a simulation of implementing countermeasures, the airflow velocity of the user-side individual air conditioning equipment 1100 (air-conditioned clothing 1110) and the set temperature of the overall air conditioner 1000 may be automatically controlled to obtain the predicted discomfort distribution shown in Figure 14B.

[0225] In accordance with condition (1), the target value of 4 m / s for the airflow velocity of the user-side individual air conditioning equipment 1100 (air-conditioned clothing 1110) is transmitted to the thermal sensation acquisition terminal device 400 of each user belonging to user areas AR1 to AR8. That is, data indicating the target value of airflow velocity of 4 m / s is transmitted from the server 200 via the network 300 to the thermal sensation acquisition terminal device 400, which serves as the user-side terminal 110 of each user belonging to user areas AR1 to AR8. The thermal sensation acquisition terminal device 400 adjusts the airflow velocity of the user-side individual air conditioning equipment 1100 so that the target value of airflow velocity of 4 m / s is obtained. A control signal is transmitted to the user-side individual air conditioning equipment 1100 via wireless means such as Bluetooth, Wi-Fi, or infrared, and the airflow velocity of the user-side individual air conditioning equipment 1100 is adjusted to the target value of 4 m / s according to the control signal. For example, the current airflow velocity can be detected, and the airflow velocity can be adjusted so that the deviation between the target airflow velocity and the detected current airflow velocity becomes zero. Alternatively, the thermal sensation acquisition terminal device 400 and the user-side individual air conditioning equipment 1100 may be connected by a wired signal line or the like to transmit control signals to the user-side individual air conditioning equipment 1100.

[0226] Furthermore, in accordance with condition (2), a target set temperature, which is 1°C higher than the current set temperature of the overall air conditioning equipment 1000 in user areas AR9 to AR17, is transmitted to the overall air conditioning equipment 1000 in user areas AR9 to AR17. That is, data indicating a suggested set temperature + 1°C is transmitted from the server 200 to the overall air conditioning equipment 1000 in user areas AR9 to AR17 via the network 300. As a result, the set temperature of the overall air conditioning equipment 1000 in user areas AR9 to AR17 is changed to a set temperature that is 1°C higher than the current set temperature. For example, with a target set temperature that is 1°C higher than the current set temperature, the airflow generated by the overall air conditioning equipment 1000 is adjusted to achieve this target value.

[0227] (Example 5)

[0228] In Example 3, instead of manually adjusting the set temperature of the central air conditioner 1000 and the individual user-side air conditioning units 1100, they may be automatically controlled.

[0229] The following explanation will omit details that overlap with those in Example 3 as appropriate.

[0230] As shown in Figure 12A, if the user's surrounding environment comfort level P1 belongs to the first region Z1, the current user's surrounding environment comfort level P1 is evaluated as "comfortable". In this case, according to condition (2), a target set temperature, for example, 1°C higher than the set temperature of the overall air conditioning unit 1000 in the user region AR to which this user belongs, is transmitted to the overall air conditioning unit 1000. That is, data indicating a target set temperature of +1°C is transmitted from the server 200 to the overall air conditioning unit 1000 in the user region AR to which the user belongs via the network 300. As a result, the set temperature of the overall air conditioning unit 1000 in the user region AR to which the user belongs is changed to a set temperature that is 1°C higher than the current set temperature. For example, the airflow of the overall air conditioning unit 1000 is adjusted so that a set temperature 1°C higher than the current set temperature is obtained as the target value.

[0231] As shown in Figure 12B, if the user's surrounding environment comfort level P1 belongs to the second region Z2, the current user's surrounding environment comfort level P1 is evaluated as "somewhat uncomfortable". In this case, according to condition (1), the target value of 2 m / s for the airflow velocity of the user-side individual air conditioning device 1100 (air-conditioned clothing 1110) is transmitted to the user's thermal sensation acquisition terminal device 400. That is, data indicating the target value of 2 m / s for the airflow velocity is transmitted from the server 200 via the network 300 to the thermal sensation acquisition terminal device 400, which is the user's terminal 110. The thermal sensation acquisition terminal device 400 adjusts the airflow velocity of the user-side individual air conditioning device 1100 so that the target value of 2 m / s is obtained. A control signal is transmitted to the user-side individual air conditioning device 1100 via wireless means such as Bluetooth, Wi-Fi, or infrared, and the airflow velocity of the user-side individual air conditioning device 1100 is adjusted to the target value of 2 m / s according to the control signal. For example, feedback control can be used to adjust the target value to 2 m / s.

[0232] As shown in Figure 12C, if the user's surrounding environment comfort level P1 belongs to the third region Z3, the current user's surrounding environment comfort level P1 is evaluated as "uncomfortable". In this case, according to condition (1), the target value of 4 m / s for the airflow velocity of the user-side individual air conditioning device 1100 (air-conditioned clothing 1110) is transmitted to the user's thermal sensation acquisition terminal device 400. That is, data indicating the target value of 4 m / s for the airflow velocity is transmitted from the server 200 via the network 300 to the thermal sensation acquisition terminal device 400, which is the user's user-side terminal 110. The thermal sensation acquisition terminal device 400 adjusts the airflow velocity of the user-side individual air conditioning device 1100 so that the target value of 4 m / s is obtained. A control signal is transmitted to the user-side individual air conditioning device 1100 via wireless means such as Bluetooth, Wi-Fi, or infrared, and the airflow velocity of the user-side individual air conditioning device 1100 is adjusted to the target value of 4 m / s according to the control signal. For example, feedback control can be used to adjust the target value to 4 m / s.

[0233] Alternatively, the thermal sensation acquisition terminal device 400 and the user-side individual air conditioning equipment 1100 may be connected by a wired connection such as a signal line, and control signals may be transmitted to the user-side individual air conditioning equipment 1100.

[0234] (Example 6)

[0235] The following describes Example 6 according to the seventh embodiment.

[0236] (Set temperature distribution screen)

[0237] Figure 15A shows the set temperature distribution screen 810A displayed on the display screen of the display device 17 of the administrator terminal 100.

[0238] The temperature distribution screen 810A displays a layout diagram RT showing the arrangement of each desk DK in the office. The layout diagram RT is a floor plan of the office, with each desk DK associated with a user name. Each desk DK is divided into a first user area AR21 and a second user area AR22. The central air conditioning units 1000A and 1000B are installed in both the first user area AR21 and the second user area AR22, respectively.

[0239] The set temperatures for the 1000A and 1000B air conditioning units are both set to 26°C.

[0240] Users belonging to the first user area AR21 are affected by the air conditioning of the central air conditioning unit 1000A. The first user area AR21 is, for example, an area where 16 desks DK are arranged. For example, user U11 performing office work at desk DK11 and user U12 performing office work at desk DK12 are affected by the air conditioning of the central air conditioning unit 1000A.

[0241] Users belonging to the second user area AR22 are affected by the air conditioning of the central air conditioning unit 1000B. The second user area AR22 is, for example, an area where 10 desks DK are arranged. For example, user U13 performing office work at desk DK13 and user U14 performing office work at desk DK14 are affected by the air conditioning of the central air conditioning unit 1000B.

[0242] (Display of thermal sensation distribution)

[0243] The thermal sensation TF, workload, clothing amount, user body temperature, desktop temperature, user body humidity, and desktop humidity data for each user U11, U12, U13, and U14, acquired by the thermal sensation acquisition terminal device 400, are stored in the database 210 of the server 200 via the network 300.

[0244] Server 200 generates thermal sensation distribution screens 811A, 812A, 813A, and 814A, described later, based on thermal sensation TF, workload, clothing amount, user body temperature, desktop temperature, user body humidity, desktop humidity, as well as separately measured outside air temperature, outside air humidity, and separately collected set temperatures of the overall air conditioning equipment 1000A and 1000B. The thermal sensation distribution screens 811A, 812A, 813A, and 814A are stored in Server 200 so that they can be displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0245] On the set temperature distribution screen 810A shown in Figure 15A, if, for example, an operation PT is performed to specify a particular desk DK11, the display screen 17A of the display device 17 of the administrator terminal 100 transitions to a thermal sensation distribution screen 811A that includes the distribution of thermal sensation TF felt by user U11 who is working in the office at the specified desk DK11.

[0246] Figure 16A illustrates the thermal sensation distribution screen 811A displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0247] The thermal sensation distribution display screen 811A includes a thermal sensation map display unit 820, a user name display unit 821, a clothing amount / work amount display unit 822, and a set temperature display unit 823.

[0248] The thermal sensation map display unit 820 shows the daily fluctuation range of the level LV for each of the following items: thermal sensation TF, user body temperature UT, desktop temperature DT, user body humidity UH, desktop humidity DH, outside air temperature ET, and outside air humidity EH. The horizontal axis represents each of the items: thermal sensation TF, user body temperature UT, desktop temperature DT, user body humidity UH, desktop humidity DH, outside air temperature ET, and outside air humidity EH, and the vertical axis represents each level LV.

[0249] Each level of the thermal comfort TF (Temperature Factor) is divided into three categories: 3 ("Hot"), 2 ("Warm"), 1 ("Slightly Warm"), 0 ("Neutral"), -1 ("Slightly Cool"), -2 ("Cool"), and -3 ("Cold").

[0250] The user body temperature (UT) levels are divided into 32, 31, 30, 29, 28, 27, 26, 25, and 24 (°C). Level 28°C is neutral, levels 32, 31, 30, and 29°C belong to the hot range, and levels 27, 26, 25, and 24°C belong to the cold range.

[0251] The desktop temperature (DT) levels are divided into 30, 29, 28, 27, 26, 25, 24, 23, and 22 (°C). Level 26°C is neutral, levels 30, 29, 28, and 27°C belong to the hot range, and levels 25, 24, 23, and 22°C belong to the cold range.

[0252] The ambient temperature (ET) levels are divided into 30, 29, 28, 27, 26, 25, 24, 23, and 22 (°C). Level LV of 26°C is neutral, levels LV of 30, 29, 28, and 27°C belong to the hot range, and levels LV of 25, 24, 23, and 22°C belong to the cold range.

[0253] The user body humidity (UH) levels are divided into 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, and 35% (%). The 55% level is neutral, the 75%, 70%, 65%, and 60% levels belong to the hot range, and the 50%, 45%, 40%, and 35% levels belong to the cold range.

[0254] Desktop humidity levels DH are divided into 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, and 35% (%). Level 55% is neutral, levels 75%, 70%, 65%, and 60% belong to the hot range, and levels 50%, 45%, 40%, and 35% belong to the cold range.

[0255] The outdoor humidity levels EH are divided into 75%, 70%, 65%, 60%, 55%, 50%, 45%, 40%, and 35% (%). Level LV of 5% is neutral, levels LV of 75%, 70%, 65%, and 60% belong to the hot range, and levels LV of 50%, 45%, 40%, and 35% belong to the cold range.

[0256] For each of the following parameters, the daily fluctuation range of the Level LV is displayed in a different hue from the background color: Thermal Sensitivity TF, User Body Temperature UT, Desktop Temperature DT, User Body Humidity UH, Desktop Humidity DH, Outdoor Temperature ET, and Outdoor Humidity EH. If the Level LV of an item falls within the hot range, it is displayed in orange (indicated by cross-hatching in the figure). If the Level LV of an item falls within the neutral range, it is displayed in green (indicated by hatching in the figure). If the Level LV of an item falls within the cold range, it is displayed in blue (indicated by halftone dots in the figure).

[0257] The thermal sensation map display unit 820 only needs to display each of the items thermal sensation TF, user body temperature UT, desktop temperature DT, user body humidity UH, desktop humidity DH, outside air temperature ET, and outside air humidity EH in a manner that allows identification of the levels LV of the hot range, neutral range, and cold range by at least one of hue, saturation, and brightness.

[0258] The username display unit 821 displays the name or user ID of user U11, as well as the location information of desk DK11.

[0259] The clothing and work volume display unit 82 displays information on the user U11's clothing ("long-sleeved work clothes + long pants") and work volume ("desk work involving movement").

[0260] The set temperature display unit 823 displays information ("26°C") about the set temperature of the overall air conditioning unit 1000A, which affects the air conditioning for user U11.

[0261] From the information displayed on the thermal comfort distribution screen 811A, the administrator can confirm, for example, that when the set temperature of the overall air conditioning unit 1000A is 26°C, the user U11's thermal comfort TF falls within the range of 1 ("slightly warm"), 0 ("neutral"), -1 ("slightly cool"), and -2 ("cool") throughout the day.

[0262] While the thermal sensation distribution screen 811A was used as a representative example and explained in detail, the same applies to the other thermal sensation distribution screens 812A, 813A, and 814A.

[0263] On the set temperature distribution screen 810A shown in Figure 15A, if, for example, an operation PT is performed to specify a particular desk DK12, the display screen 17A of the display device 17 of the administrator terminal 100 transitions to a thermal sensation distribution screen 812A that includes the distribution of thermal sensation TF felt by user U12 who is working in the office at the specified desk DK12.

[0264] Figure 17A illustrates the thermal sensation distribution screen 812A displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0265] From the information displayed on the thermal comfort distribution screen 812A, the administrator can confirm, for example, that when the set temperature of the overall air conditioning unit 1000A is 26°C, the user U12's thermal comfort TF remains within the range of 0 ("neutral"), -1 ("slightly cool"), and -2 ("cool") throughout the day.

[0266] On the set temperature distribution screen 810A shown in Figure 15A, if, for example, an operation PT is performed to specify a particular desk DK13, the display screen 17A of the display device 17 of the administrator terminal 100 transitions to a thermal sensation distribution screen 813A that includes the distribution of thermal sensation TF felt by user U13 who is working in the office at the specified desk DK13.

[0267] Figure 18A illustrates the thermal sensation distribution screen 813A displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0268] From the display content of the warm / cold feeling distribution screen 813A, for example, when the set temperature of the overall air conditioner 1000B is 26°C, the administrator can confirm that the warm / cold feeling TF of the user U13 stays within the range of 3 ("hot"), 2 ("warm"), 1 ("slightly warm"), and 0 ("neutral") throughout the day.

[0269] On the set temperature distribution screen 810A shown in FIG. 15A, for example, when an operation PT for instructing a specific desk DK14 is performed, the display screen 17A of the display device 17 of the administrator-side terminal 100 transitions to a warm / cold feeling distribution screen 814A including the distribution of the warm / cold feeling TF felt by the user U14 who is performing office work at the instructed specific desk DK14.

[0270] FIG. 19A illustrates the warm / cold feeling distribution screen 814A displayed on the display screen 17A of the display device 17 of the administrator-side terminal 100.

[0271] From the display content of the warm / cold feeling distribution screen 814A, for example, when the set temperature of the overall air conditioner 1000B is 26°C, the administrator can confirm that the warm / cold feeling TF of the user U14 stays within the range of 2 ("warm"), 1 ("slightly warm"), 0 ("neutral"), and -1 ("slightly cool") throughout the day.

[0272] As a result, the administrator can make the following judgments.

[0273] 1) At the current set temperature of 26°C of the overall air conditioner 1000A, the warm / cold feeling TF of the users belonging to the first user area AR21 stays within a comfortable range. Therefore, it is presumed that for the users belonging to the first user area AR21, it is possible to raise the set temperature of the overall air conditioner 1000A by 2°C from the current temperature without proposing the use (wearing) of the user-side individual air conditioner 1100 (air conditioning suit 1110) or changing the amount of clothing.

[0274] 2) At the current set temperature of 26°C of the overall air conditioner 1000B, the temperature feeling TF of users belonging to the second user area AR22 may fall within an uncomfortable range. Therefore, regarding the users belonging to the second user area AR22, it is difficult to raise the set temperature of the overall air conditioner 1000B from the current set temperature of 26°C by 2°C without proposing wearing the user-side individual air conditioner 1100 (air conditioning clothing 1110) or changing the amount of clothing worn, and it is presumed that raising the set temperature requires attention.

[0275] (Change of set temperature)

[0276] FIG. 15B shows a set temperature distribution screen 810B in which the set temperatures of the overall air conditioners 1000A and 1000B are switched from the set temperature of 26°C in the set temperature distribution screen 810A to 28°C.

[0277] Corresponding to the set temperature distribution screen 810B shown in FIG. 15B, a temperature feeling distribution screen 811B shown in FIG. 16B, a temperature feeling distribution screen 812B shown in FIG. 17B, a temperature feeling distribution screen 813B shown in FIG. 18B, and a temperature feeling distribution screen 814B shown in FIG. 19B can be displayed on the display screen 17A of the display device 17 of the administrator-side terminal 100.

[0278] Note that the display contents of the temperature feeling distribution screen 811B, the temperature feeling distribution screen 812B, the temperature feeling distribution screen 813B, and the temperature feeling distribution screen 814B are the same as those of the temperature feeling distribution screen 811A, the temperature feeling distribution screen 812A, the temperature feeling distribution screen 813A, and the temperature feeling distribution screen 814A, respectively, except that the set temperatures of the overall air conditioners 1000A and 1000B are switched from the set temperature of 26°C to 28°C.

[0279] That is, on the set temperature distribution screen 810B shown in FIG. 15B, for example, when an operation PT for instructing a specific desk DK11 is performed, the display screen 17A of the display device 17 of the administrator-side terminal 100 transitions to a temperature feeling distribution screen 812B including the distribution of the temperature feeling TF felt by the user U11 performing office work at the instructed specific desk DK11.

[0280] Figure 16B illustrates the thermal sensation distribution screen 811B displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0281] From the information displayed on the thermal comfort distribution screen 811B, for example, if the set temperature of the overall air conditioning unit 1000A is switched from 26°C to 28°C, the administrator can confirm that user U11's thermal comfort TF shifted to the range of 2 ("warm") and 1 ("slightly warm") for the duration of the day.

[0282] On the set temperature distribution screen 810B shown in Figure 15B, if, for example, an operation PT is performed to specify a particular desk DK12, the display screen 17A of the display device 17 of the administrator terminal 100 transitions to a thermal sensation distribution screen 812B that includes the distribution of thermal sensation TF felt by user U12 who is working in the office at the specified desk DK12.

[0283] Figure 17B illustrates the thermal sensation distribution screen 812B displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0284] From the information displayed on the thermal comfort distribution screen 812B, for example, if the set temperature of the overall air conditioning unit 1000A is switched from 26°C to 28°C, the administrator can confirm that user U12's thermal comfort TF has shifted to the range of 1 ("slightly warm") and 0 ("neutral") for the duration of the day.

[0285] On the set temperature distribution screen 810B shown in Figure 15B, if, for example, an operation PT is performed to specify a particular desk DK13, the display screen 17A of the display device 17 of the administrator terminal 100 transitions to a thermal sensation distribution screen 813B that includes the distribution of thermal sensation TF felt by user U13 who is working in the office at the specified desk DK13.

[0286] Figure 18B illustrates the thermal sensation distribution screen 813B displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0287] From the information displayed on the thermal comfort distribution screen 813B, for example, if the set temperature of the overall air conditioning unit 1000B is switched from 26°C to 28°C, the administrator can confirm that user U13's thermal comfort TF shifted to the range of 3 ("hot") and 2 ("warm") for the duration of the day.

[0288] On the set temperature distribution screen 810B shown in Figure 15B, if, for example, an operation PT is performed to specify a particular desk DK14, the display screen 17A of the display device 17 of the administrator terminal 100 transitions to a thermal sensation distribution screen 814B that includes the distribution of thermal sensation TF felt by user U14 who is working in the office at the specified desk DK14.

[0289] Figure 19B illustrates the thermal sensation distribution screen 814B displayed on the display screen 17A of the display device 17 of the administrator terminal 100.

[0290] From the information displayed on the thermal sensation distribution screen 814B, for example, if the set temperature of the overall air conditioning unit 1000B is switched from 26°C to 28°C, the administrator can confirm that user U14's thermal sensation TF shifted to the range of 3 ("hot"), 2 ("warm"), and 1 ("slightly warm") throughout the day.

[0291] As a result, the administrator can make the following decisions:

[0292] 3) When the set temperature of the overall air conditioning unit 1000A is switched from 26°C to 28°C, the thermal comfort TF of users belonging to the first user area AR21 shifts from the comfortable range to the uncomfortable range. For this reason, it can be determined that it is desirable to gradually increase the set temperature of the overall air conditioning unit 1000A from 26°C in increments of 1°C for the first user area AR21. Furthermore, for users belonging to the first user area AR21, especially those whose thermal comfort TF falls into the uncomfortable range, it can be determined that it is desirable to increase the set temperature of the overall air conditioning unit 1000A from 26°C by 1°C and then suggest the use (wearing) of individual user-side air conditioning units 1100 (air-conditioned clothing 1110) or a change in the amount of clothing worn.

[0293] 4) When the set temperature of the overall air conditioner 1000B is switched from 26°C to 28°C, the temperature feeling TF of the users belonging to the second user area AR22 shifts to a more uncomfortable range compared to the users belonging to the first user area AR21. Therefore, regarding the second user area AR22, while gradually increasing the set temperature of the overall air conditioner 1000B from 26°C by 1°C at a time, it can be determined that it is essential to propose the use (wearing) of the user-side individual air conditioner 1100 (air conditioning clothing 1110) and the change of clothing amount to the users belonging to the second user area AR22.

[0294] As a result, the administrator can take the following measures.

[0295] 5) As a result of increasing the set temperature of the overall air conditioner 1000A or 1000B, for the users whose temperature feeling is in the uncomfortable range, it is possible to propose the use (wearing) of the user-side individual air conditioner 1100 (air conditioning clothing 1110) and the change of clothing amount via e-mail or the like. For example, when a user whose temperature feeling is in the uncomfortable range is indicated on the display screen 17A of the display device 17 of the administrator-side terminal 100, an e-mail containing information proposing the use (wearing) of the user-side individual air conditioner 1100 (air conditioning clothing 1110) and the change of clothing amount is transmitted to the temperature feeling acquisition terminal device 400 of the corresponding user via the server 200 functioning as a mail server and is received by the temperature feeling acquisition terminal device 400. As a result, the user can shift the temperature feeling TF to a comfortable range by checking the display content on the display screen 401 of the temperature feeling acquisition terminal device 400, using (wearing) the user-side individual air conditioner 1100 (air conditioning clothing 1110), or changing the clothing amount.

[0296] In the above description, the set temperature distribution screen 810A shown in FIG. 15A, the temperature feeling distribution screen 811A shown in FIG. 16A, the temperature feeling distribution screen 812A shown in FIG. 17A, the temperature feeling distribution screen 813A shown in FIG. 18A, and the temperature feeling distribution screen 814A shown in FIG. 19A are displayed on separate display screens. However, it is also possible to implement displaying any two or more of these screens on the same display screen.

[0297] For example, the set temperature distribution screen 810A shown in Figure 15A, the thermal sensation distribution screen 811A shown in Figure 16A, the thermal sensation distribution screen 812A shown in Figure 17A, the thermal sensation distribution screen 813A shown in Figure 18A, and the thermal sensation distribution screen 814A shown in Figure 19A may be simultaneously displayed in a list on the display screen 17A of the display device 17 of the administrator terminal 100. This allows the distribution of thermal sensation for each user U11, U12 belonging to the first user area AR21 and each user U13, U14 belonging to the second user area AR22 to be viewed in a list along with the layout diagram RT when the set temperature of the overall air conditioning equipment 1000A and 1000B is set to 26℃.

[0298] Similarly, the set temperature distribution screen 810B shown in Figure 15B, the thermal sensation distribution screen 811B shown in Figure 16B, the thermal sensation distribution screen 812B shown in Figure 17B, the thermal sensation distribution screen 813B shown in Figure 18B, and the thermal sensation distribution screen 814B shown in Figure 19B may be simultaneously displayed in a list on the display screen 17A of the display device 17 of the administrator terminal 100. This allows the distribution of thermal sensation for each user U11, U12 belonging to the first user area AR21 and each user U13, U14 belonging to the second user area AR22 to be viewed in a list along with the layout diagram RT when the set temperature of the overall air conditioning equipment 1000A and 1000B is set to 28℃.

[0299] Furthermore, if the administrator decides to raise the set temperature of the overall air conditioning unit 1000A or 1000B, and as a result the user's temperature is in an uncomfortable range, the administrator will send a suggestion via email or other means to use (wear) the user's individual air conditioning unit 1100 (air-conditioned clothing 1110) or change the amount of clothing worn. This process may also be performed automatically.

[0300] For example, if the computer automatically determines that the temperature setting of the overall air conditioning unit 1000A or 1000B has been increased, and the user's temperature sensation has entered an uncomfortable range, the computer may automatically send an email to the user's temperature sensation acquisition terminal device 400 that has entered that uncomfortable range, suggesting the use (wearing) of the user's individual air conditioning unit 1100 (air-conditioned clothing 1110) or a change in the amount of clothing worn.

[0301] According to Example 6, it is possible to easily understand the changes in the thermal sensation distribution according to the set temperature of the overall air conditioning equipment.

[0302] (Example 7)

[0303] The thermal sensation acquisition terminal device, air conditioning equipment adjustment system, and predicted discomfort distribution display device and thermal sensation distribution display device described herein are not limited to offices or factories, but can be applied to any space that has an air-conditioned environment. For example, they can be applied to transportation equipment such as automobiles and buses, hospitals, and general houses.

[0304] When applied to the interiors of automobiles or buses, the vehicle's air conditioner can be used as the overall air conditioning unit, and air-conditioned cushions with fans can be installed on the seats to serve as individual air conditioning units for the users.

[0305] When applied to shared hospital rooms, the air conditioner installed in the room can be used as the overall air conditioning unit, and a bed mattress with an air conditioning (cooling) fan can be provided on the bed to serve as the individual air conditioning unit for the user.

[0306] When applied to a bedroom in a typical house, the air conditioner installed in the bedroom can be considered the overall air conditioning unit, and a bed mattress with an air conditioning (cooling) fan can be installed on the bed and used as the individual air conditioning unit for the user.

[0307] Furthermore, in the above-described embodiment 1, it is assumed that the user directly operates the input device 16 of the thermal sensation acquisition terminal device 400, which is composed of a smartphone or the like, by moving their hand to select or input the user's thermal sensation TF, amount of clothing worn, and workload. However, the method of acquiring the user's thermal sensation TF, amount of clothing worn, and workload is arbitrary. The user's thermal sensation TF, amount of clothing worn, and workload may also be acquired by reading the area selected by the user on the display screen using information on the user's eye movement and vital information.

[0308] Alternatively, the user's thermal sensation TF may be obtained by analyzing the user's voice or by analyzing images of the user's face. By using such acquisition methods, information on the thermal sensation of users who are unable to manually select or input information due to being in the middle of work or driving can be automatically acquired.
