Description
[Technical Field]
[0001] The present disclosure generally relates to an environmental control system, an environmental control method, and a program, and more particularly to an environmental control system, an environmental control method, and a program for controlling the temperature of a space. [Background technology]
[0002] The central air-conditioning control system (environmental control system) described in Patent Document 1 includes an indoor water vapor pressure detection means, an outdoor water vapor pressure detection means, and a temperature detection means. The central air-conditioning control system compares the indoor water vapor pressure detected by the indoor water vapor pressure detection means, the outdoor water vapor pressure detected by the outdoor water vapor pressure detection means, the water vapor pressure inside the exterior wall calculated based on known property values of the exterior wall material, and the saturated water vapor pressure calculated based on the temperatures of the materials on both sides of the air layer inside the exterior wall detected by the temperature detection means. The central air-conditioning control system then flows air into the air layer inside the exterior wall when the water vapor pressure inside the exterior wall is approximately equal to the saturated water vapor pressure.
[0003] However, what kind of environment a user finds comfortable varies from person to person, and therefore the environmental control system described in Patent Document 1 may not be able to provide a comfortable environment for the user due to individual differences.

[0010] In the following embodiments, the environmental control system, the environmental control method, and the program of the present disclosure will be described with reference to the accompanying drawings. However, the following embodiments are merely a part of the various embodiments of the present disclosure. The following embodiments can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved.
[0011] (Embodiment 1) (overview) The environmental control system 1 of this embodiment shown in FIG. 1 is used to control a control target parameter such as the temperature of a space. The space is, for example, an indoor space of a facility. The facility is, for example, a building or a mobile object. Examples of buildings as facilities include homes, office buildings, factories, commercial complexes, libraries, art galleries, museums, amusement facilities, airports, train stations, hotels, nursing homes, and hospitals. Examples of mobile objects as facilities include ships, railroad cars, and aircraft.
[0012] As shown in FIG. 1, the environmental control system 1 of this embodiment controls at least one control target parameter, which is a part of multiple environmental values related to the environment of a space. The multiple environmental values include the temperature and water vapor pressure of the space. The environmental control system 1 includes a first acquisition unit 21, a second acquisition unit 22, a derivation unit 23, and a control unit 24. The first acquisition unit 21 acquires user information including information on the user's metabolic rate and information on the user's thermal resistance. The second acquisition unit 22 acquires default values of one or more environmental values from the multiple environmental values, excluding at least one control target parameter. The derivation unit 23 calculates at least one control value based on the user information acquired by the first acquisition unit 21 and the default values of the one or more environmental values acquired by the second acquisition unit 22. The at least one control value is a value of the at least one control target parameter when a predetermined relationship exists between the user information, the default values of the one or more environmental values, and the at least one control target parameter. The control unit 24 controls the environmental device 6 based on the at least one control value calculated by the derivation unit 23. The environmental device 6 adjusts at least one controlled parameter of the space.
[0013] According to this embodiment, the environmental control system 1 can control the environment of the space so that the predetermined relationship is satisfied. This makes it possible to maintain the comfort of the space. Since the predetermined relationship is related to user information, it is more likely that an environment that each user finds comfortable can be provided, taking into account differences in how each user feels about a certain environment.
[0014] In this embodiment, as an example, a case will be described in which the environmental control system 1 is used to control the environment in a space when a user goes to sleep. By using the environmental control system 1, an environment in which the user is likely to get a good night's sleep can be provided.
[0015] (detail) (1) Overall structure As shown in FIG. 1, the environmental control system 1 is used, for example, together with an information terminal 3, a gateway 4, a control unit 5, multiple (three in FIG. 1) environmental devices 6, and multiple (two in FIG. 1) sensors 7.
[0016] (2) Environmental control system The environmental control system 1 includes a processing unit 2, a communication unit 12, and a storage unit 13.
[0017] The communication unit 12 includes a communication interface device. The communication unit 12 is capable of communicating with the information terminal 3 and the gateway 4 via the communication interface device. In this disclosure, "capable of communication" means that signals can be sent and received directly or indirectly via a network, a repeater, or the like, by an appropriate communication method such as wired communication or wireless communication.
[0018] The storage unit 13 is, for example, a read-only memory (ROM), a random access memory (RAM), an electrically erasable programmable read-only memory (EEPROM), etc. The storage unit 13 stores information used in the environmental control system 1.
[0019] The processing unit 2 includes a computer system having one or more processors and a memory. At least some of the functions of the processing unit 2 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be provided by being recorded on a non-transitory recording medium such as a memory card.
[0020] The processing unit 2 has a first acquisition unit 21, a second acquisition unit 22, a derivation unit 23, a control unit 24, a metabolic rate derivation unit 25, and a thermal resistance derivation unit 26. Note that these merely indicate functions realized by the processing unit 2, and do not necessarily indicate actual configurations.
[0021] The first acquisition unit 21 acquires user information. More specifically, the first acquisition unit 21 acquires the user information via the communication unit 12. More specifically, the user information is input to the information terminal 3 by the user operating the information terminal 3, and is provided from the information terminal 3 to the first acquisition unit 21.
[0022] The second acquisition unit 22 acquires one or more default values of the environment values. More specifically, the second acquisition unit 22 acquires the one or more default values of the environment values via the communication unit 12.
[0023] Examples of environmental values are the temperature of the space, the humidity of the space, the wind speed in the space, and the radiation temperature of the walls that make up the space. The environmental values are preferably environmental values in the space near the user. For example, the temperature of the space as an environmental value is preferably specifically the temperature in the user's vicinity. Furthermore, the wind speed in the space as an environmental value is preferably specifically the wind speed in the user's vicinity.
[0024] The default value is a value that is determined before the derivation unit 23 performs processing to determine at least one control value. The default value is, for example, a default value, a setting value, or a measurement value. The default value or setting value is, for example, input to the information terminal 3 by the user operating the information terminal 3, and is provided from the information terminal 3 to the second acquisition unit 22. The setting value is a value that determines the operating state (output magnitude, etc.) of the multiple environmental devices 6. The setting value is, for example, output from the multiple environmental devices 6. On the other hand, the default value can be determined regardless of the operating state of the multiple environmental devices 6. The measurement value is, for example, output from the multiple sensors 7.
[0025] The derivation unit 23 determines at least one control value. The control unit 24 controls the environmental devices 6 to be controlled among the plurality of environmental devices 6 based on the at least one control value determined by the derivation unit 23. In this way, the control unit 24 adjusts at least one parameter to be controlled in the space. The control value is, for example, a value that specifies a setting value (such as a set temperature) of the parameter to be controlled (such as a temperature). In this case, the setting value of each environmental device 6 is set based on a command signal output from the control unit 24 based on the control value.
[0026] The metabolic rate derivation unit 25 calculates the metabolic rate of the user based on the user's physical information. The user's physical information is an example of information related to the user's metabolic rate. The user's physical information is input to the information terminal 3 by the user operating the information terminal 3, and is provided from the information terminal 3 to the first acquisition unit 21.
[0027] As an example, the user's physical information is information about at least one of the user's age, sex, height, and weight. As an example, the metabolic rate derivation unit 25 calculates the user's metabolic rate by referring to a correspondence table or a formula that indicates the relationship between the user's physical information and the user's metabolic rate.
[0028] The thermal resistance derivation unit 26 calculates the thermal resistance of the user based on clothing information about the user's clothes and bedding information about the bedding used by the user. The clothing information and bedding information are each an example of information about the user's thermal resistance. The clothing information and bedding information are input to the information terminal 3 by the user operating the information terminal 3, and are provided from the information terminal 3 to the first acquisition unit 21.
[0029] The user's clothing is specifically the clothing (nightwear) worn by the user when sleeping. The bedding used by the user is, for example, a comforter, a mattress, a blanket, a slatted floor, etc. As an example, the thermal resistance derivation unit 26 determines the user's thermal resistance by referring to a correspondence table or a calculation formula that shows the relationship between the clothing information, the bedding information, and the user's thermal resistance.
[0030] The environmental control system 1 is realized, for example, by cloud computing. The environmental control system 1 may also be realized, for example, by a server computer or a personal computer installed in a facility. Alternatively, the environmental control system 1 may be realized by a mobile terminal such as a mobile phone (smartphone, etc.) or a tablet terminal. Furthermore, an information terminal 3 having a function for accepting input of user information may also have the function of the environmental control system 1. Alternatively, an operation terminal (remote controller, etc.) used by a user to operate the environmental equipment 6 may also have the function of the environmental control system 1.
[0031] (3) Information terminal Examples of the information terminal 3 include a mobile terminal such as a mobile phone or a tablet terminal, and a personal computer. In this embodiment, the information terminal 3 will be described as a mobile phone (smartphone).
[0032] As shown in FIG. 1, the information terminal 3 includes a processing unit 31, a communication unit 32, a storage unit 33, a display unit , and an operation unit .
[0033] The processing unit 31 performs overall control of the information terminal 3. The processing unit 31 includes a computer system having one or more processors and a memory. At least some of the functions of the processing unit 31 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.
[0034] The communication unit 32 includes a communication interface device, and is capable of communicating with the environmental control system 1 via the communication interface device.
[0035] The storage unit 33 is, for example, a read only memory (ROM), a random access memory (RAM), an electrically erasable programmable read only memory (EEPROM), etc. The storage unit 33 stores information used by the information terminal 3.
[0036] The display unit 34 is a display that displays various types of information, such as a setting screen for inputting user information.
[0037] The operation unit 35 accepts user operations. The operation unit 35 is composed of, for example, a plurality of buttons, a touch panel or a touch panel display, a voice input interface, or a combination of these. The touch panel display of the operation unit 35 may also serve as the display unit 34.
[0038] (4) Gateway The gateway 4 is installed in a facility where multiple environmental devices 6 are installed. The gateway 4 relays communication between the environmental control system 1 and the control unit 5.
[0039] (5) Control unit The control unit 5 is installed in a facility where multiple environmental devices 6 are installed. The control unit 5 is capable of communicating with the environmental control system 1. In this embodiment, the control unit 5 communicates with the environmental control system 1 via a gateway 4. The control unit 5 is also capable of communicating with multiple environmental devices 6 and multiple sensors 7. The communication method between the control unit 5 and the environmental control system 1 is, for example, a communication method conforming to the Ethernet (registered trademark) standard, Wi-Fi (registered trademark), or the like. The communication method between the control unit 5 and the multiple environmental devices 6 and multiple sensors 7 is, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like.
[0040] The control unit 5 sets the setting values of each of the plurality of environmental devices 6 based on a command signal output from the control unit 24 of the environmental control system 1. The control unit 5 also collects detection signals output from each of the plurality of sensors 7 and transmits them to the environmental control system 1 via the gateway 4.
[0041] (6)Environmental equipment The plurality of environmental devices 6 are installed in a facility and adjust the plurality of environmental values of the facility's space. The plurality of environmental devices 6 may include an air conditioner or the like that adjusts the temperature of the space. The plurality of environmental devices 6 may include at least one of a humidifier and a dehumidifier that adjusts the humidity of the space. The plurality of environmental devices 6 may include a ventilation device that ventilates the space. The plurality of environmental devices 6 may include a floor heating device, a wall heating panel, or the like that adjusts the temperature of the space and the temperature of the walls that make up the space. However, the types of environmental devices 6 are not limited to these. Furthermore, the term "wall" as used in this disclosure does not only refer to components that make up a space and have surfaces perpendicular to the ground, but also includes components such as floors and ceilings that are not perpendicular to the ground.
[0042] The setting values of each of the plurality of environmental devices 6 can be determined by the control unit 24 of the environmental control system 1. The setting values can also be determined by user operation.
[0043] Furthermore, each of the multiple environmental devices 6 may provide information about its own setting values to the second acquisition unit 22 of the environmental control system 1. For example, if the environmental device 6 is an air conditioner, the setting values are the set temperature and set air speed, etc. If the environmental device 6 is a humidifier or dehumidifier, the setting value is the set humidity, etc. If the environmental device 6 is a ventilation device, the setting value is the set air speed, etc. If the environmental device 6 is a floor heating device and / or a wall heating panel, the setting value is the set temperature, etc.
[0044] (7) Sensor A plurality of sensors 7 are installed in a facility where a plurality of environmental devices 6 are installed. Each of the plurality of sensors 7 detects an environmental value and outputs a detection signal including information about the measured value of the environmental value.

The multiple sensors 7 may include a wind speed sensor that detects the wind speed in the space. The multiple sensors 7 may include a radiation temperature sensor that detects the radiation temperature of the walls that form the space.
[0046] At least one of the plurality of sensors 7 may be incorporated in any one of the environmental devices 6.
[0047] (8) Multiple environmental values and controlled parameters In this embodiment, as an example, the multiple environmental values used in the environmental control system 1 are the temperature of the space and the water vapor pressure of the space. Furthermore, among the multiple environmental values, the parameter to be controlled is the temperature of the space. In the following description, when simply referring to "temperature," it refers to the temperature of the space, when simply referring to "water vapor pressure," it refers to the water vapor pressure of the space, and when simply referring to "humidity," it refers to the humidity of the space.
[0048] In this embodiment, the plurality of environmental devices 6 includes an air conditioner, and the air conditioner adjusts the temperature of the space based on a command signal output from the control unit 24 of the environmental control system 1. The derivation unit 23 of the environmental control system 1 determines a control value for the temperature of the space based on user information and a default value for the humidity of the space.
[0049] (9) Deriving the control value Next, a process in which the derivation unit 23 determines the control value of the temperature as a parameter to be controlled, that is, the set value of the temperature, will be described.
[0050] As described above, the derivation unit 23 determines at least one control value, which is the value of at least one parameter to be controlled when there is a predetermined relationship between the user information, the one or more predetermined values of the environmental values, and the at least one parameter to be controlled, based on the user information acquired by the first acquisition unit 21 and the one or more predetermined values of the environmental values acquired by the second acquisition unit 22. In this embodiment, the derivation unit 23 determines the set value of the temperature based on the user information and the predetermined value (default value) of the humidity.
[0051] The predetermined relationship is a relationship that realizes an environment in which the user is likely to get a good night's sleep. Specifically, the predetermined relationship is a relationship when the user's metabolic rate is in equilibrium with the user's heat loss. The relationship in this case is expressed by [Equation 1], as shown in the literature "A study on the thermal comfort in sleeping environments in the subtropics - Developing a thermal comfort model for sleeping environments" (Zhongping Lin, Shiming Deng). However, when the user's metabolic rate is 40 [W / m 2 ]Assume that.
[0052]
number
[0053] R t [m 2 ·℃ / W] is the thermal resistance of the user, including the thermal resistance of air and bedding. r [℃] is the radiation temperature of the walls that make up the space. h c [W / (m 2 ·K)] is the heat transfer coefficient at the body surface. h c changes depending on the wind speed. a [℃] is the temperature of the space (room temperature). a [kPa] is the water vapor pressure in the space.
[0054] [Mathematical formula 1] is an equation that expresses the following relationship: (Metabolic rate) = (Sensible heat loss through the skin) + (Latent heat loss through the skin) + (Sensible heat loss through respiration) + (Latent heat loss through respiration) Metabolic rate M [W / m 2 ], [Number 1] is transformed into [Number 2].
[0055]
number
[0056] In this embodiment, t r =t a Then, [Number 1] and [Number 2] are c This is an equation that does not include [Equation 2]. r The value of is calculated as the control value by the derivation unit 23.
[0057] The metabolic rate M is calculated by the metabolic rate deriving unit 25 based on the user's physical information. Known formulas for calculating the metabolic rate M include the Ganpule formula, the Harris-Benedict formula, the Schofield formula, the FAO / WHO / UNU formula, and the DuBois formula. The metabolic rate in a specific situation (time period) can be calculated, for example, by multiplying the basal metabolic rate calculated from these formulas by a predetermined coefficient. When calculating the set temperature when the user goes to bed, the predetermined coefficient is set to, for example, 1, and when calculating the set temperature when the user wakes up, the predetermined coefficient is set to, for example, 1.4.
[0058] In the Ganpule formula, the basal metabolic rate BMR_M for men is expressed by [Equation 3], and the basal metabolic rate BMR_F for women is expressed by [Equation 4].
[0059]
number
[0060]
number
[0061] W [kg] is the user's weight, H [cm] is the user's height, and A [years] is the user's age.
[0062] Thermal resistance R t is calculated by the thermal resistance deriving unit 26 based on the user's clothing information and bedding information. The thermal resistance deriving unit 26 further calculates the thermal resistance R based on information about the user's sleeping position. t The thermal resistance R t An example of how to calculate this will be explained in the next section.
[0063] Water vapor pressure P a is calculated from the default humidity value, which is, for example, 55% RH.
[0064] From the above information, the derivation unit 23 calculates the temperature t a is calculated as a control value (setting value). Then, the control unit 24 calculates the temperature t a The control unit 5 outputs a command signal including the information to the control unit 5. The control unit 5 controls the air conditioner (environmental equipment 6) based on the command signal. For example, the control unit 5 sets the set temperature of the air conditioner (environmental equipment 6) to t r (As mentioned above, t r =t a ).
[0065] (10) Derivation of thermal resistance For example, the user selects the type of clothing and bedding to be used when sleeping from options displayed on the display unit 34 of the information terminal 3. Variable values corresponding to each type of clothing and bedding are stored in advance in the storage unit 13 of the environmental control system 1. Using these variables, the thermal resistance derivation unit 26 calculates the thermal resistance R t Ask for.
[0066] Examples of options for deriving thermal resistance are listed below. Options for clothing covering the upper body include long-sleeved clothing, short-sleeved clothing, a tank top, and no clothing. Options for clothing covering the lower body include long pants, shorts, and no clothing. Options for bedding (comforter) covering the body include a towel blanket, a thin comforter, a down comforter, a blanket, other bedding, and no bedding. Options for body parts covered by the bedding include below the face, below the chest, and only the abdomen. Options for bedding placed under the body include a futon, a mattress, and other bedding. Options for sleeping positions include lying on your back, on your side, and prone.
[0067] Corresponding to each answer to the clothing or bedding options, the cl0 value (amount of clothing worn) of that clothing or bedding is stored in the memory unit 13. The cl0 values of clothing and bedding are determined in advance, for example, by measuring the amount of heat generated using a thermal mannequin.
[0068] For options of body parts covered by bedding (comforter) that covers the body from above, a first coefficient to be multiplied by the cl0 value of the bedding is stored in the memory unit 13. The wider the area of the body that the bedding covers, the larger the first coefficient. For options of sleeping positions, a second coefficient to be multiplied by the cl0 value of the bedding laid under the body is stored in the memory unit 13. The larger the contact area between the bedding and the user is for a sleeping position, the larger the second coefficient is.
[0069] For example, the thermal resistance derivation unit 26 calculates the sum of the clO values from the responses as the clO value of the user. As a specific example, the thermal resistance derivation unit 26 calculates the clO value (CLO_TTL1) when the user is asleep using [Equation 5].
[0070]
number
[0071] Here, CLO_TOP is the clo value of the clothes covering the upper body, CLO_DWN is the clo value of the clothes covering the lower body, and CLO_UND is the clo value of underwear, which are constant values regardless of user input, for example. BED_TOP is the clo value of the bedding covering the body from above, BED_HTW is the first coefficient mentioned above, BED_DWN is the clo value of the bedding placed underneath the body, and BED_POS is the second coefficient mentioned above.
[0072] As a specific example, the thermal resistance derivation unit 26 obtains the clO value (CLO_TTL2) when the user wakes up (immediately after getting out of bed) using [Equation 6].
[0073]
number
[0074] Here, CLO_AIR is the thermal resistance between the skin and the air. CLO_AIR is a constant value regardless of the user's input, for example.
[0075] The thermal resistance derivation unit 26 multiplies the clO value of the user thus obtained by a predetermined coefficient to obtain the thermal resistance of the user. In this embodiment, the predetermined coefficient is 0.155.
[0076] It is possible to select multiple items of bedding to cover the body. When multiple items of bedding are selected, the thermal resistance derivation unit 26 calculates the user's clO value based on the clO values of each item of bedding. For example, in [Equation 5] and [Equation 6], BED_TOP (the clO value of the bedding that covers the body) can be set to the sum of the clO values of each item of bedding.
[0077] (11) Operation flow Next, the operation flow of the environmental control system 1 will be described with reference to Figures 2 and 3. Note that Figure 2 shows only one example of the operation flow of the environmental control system 1, and the order of processes may be changed as appropriate, and processes may be added or omitted as appropriate.
[0078] During the period before the user's bedtime t1, the set temperature of the air conditioner (environmental device 6) is the temperature Te1 set by the user's operation. Before bedtime t1, the user operates the operation unit 35 of the information terminal 3 to input user information. The user information includes information about the user's metabolic rate (age, gender, etc.) and information about the user's thermal resistance (clothing information, bedding information, etc.). Note that the next time the environmental control system 1 is used, the user information input the previous time may be applied, in which case input of user information can be omitted.
[0079] The user information is acquired by the first acquisition unit 21 of the environmental control system 1 (step ST1: Yes). Furthermore, for humidity as an environmental value, a predetermined value (here, a default value) is acquired by the second acquisition unit 22 (step ST2: Yes). The predetermined value is, for example, pre-stored in the storage unit 13 of the environmental control system 1 and is read out from the storage unit 13.
[0080] The derivation unit 23 calculates a temperature control value (set temperature) based on the user information acquired by the first acquisition unit 21 and the preset value acquired by the second acquisition unit 22. Specifically, first, the metabolic rate derivation unit 25 calculates the user's metabolic rate based on physical information included in the user information (step ST3). Furthermore, the thermal resistance derivation unit 26 calculates the user's thermal resistance based on clothing information, bedding information, and the like included in the user information (step ST4). Here, the thermal resistance derivation unit 26 calculates the thermal resistance using [Equation 5] out of [Equation 5] and [Equation 6]. Thereafter, the derivation unit 23 calculates a temperature control value using [Equation 2] based on the user's metabolic rate, the user's thermal resistance, and the preset value of humidity (water vapor pressure) (step ST5).
[0081] Next, the control unit 24 controls at least one environmental device 6 (step ST6). The control unit 24 starts controlling at least one environmental device 6, for example, when the current time reaches a predetermined bedtime t1 set by the user, or when the user performs a predetermined operation on the information terminal 3. Here, the control unit 24 transmits a command signal to the control unit 5, specifying the set temperature of an air conditioner, which is the environmental device 6. In response to this, the control unit 5 sets the set temperature of the air conditioner to the temperature Te2 calculated by the derivation unit 23. This makes it possible to provide an environment that each user finds comfortable when going to bed, and to promote a good night's sleep for the user. In the example shown in FIG. 3, Te2 <Te1である。
[0082] Thereafter, as shown in FIG. 3, at time t2, a predetermined time before the preset wake-up time t3, the control unit 24 increases the set temperature of the air conditioner. More specifically, the control unit 24 gradually increases the set temperature so that the set temperature reaches temperature Te3 at wake-up time t3. Temperature Te3 is equal to the set temperature Te1 up to bedtime t1. When gradually increasing the set temperature, the set temperature may be changed continuously or in a stepped manner. After wake-up time t3, the control unit 24 ends control of the air conditioner (step ST7), and the set temperature of the air conditioner is determined by user operation.
[0083] If the set temperature is Te2 at wake-up time t3, the user may feel cold when they get out of bed, but as described above, by raising the set temperature, the possibility of the user feeling cold can be reduced.
[0084] At least one of the temperatures Te1 and Te3 may be a temperature (control value) calculated based on the thermal resistance calculated using [Equation 6] out of [Equation 5] and [Equation 6]. [Equation 6] is an equation for calculating the thermal resistance of a user when the user is not wearing bedding. In other words, when the user wakes up, the control unit 24 may control the environmental device 6 based on the control value calculated based on the thermal resistance of the user when the user is not wearing bedding. This makes it possible to provide an environment in which each user feels comfortable when they wake up.
[0085] (Embodiment 2) The following describes an environmental control system 1 according to embodiment 2. The same components as those in embodiment 1 are denoted by the same reference numerals and the description thereof will be omitted.
[0086] In the above-described first embodiment, t r =t a On the other hand, in this embodiment, the control value (temperature setting value) is calculated by assuming that t r =t a The control value (temperature setting value) is calculated assuming that t r =t a does not necessarily hold, [Equation 2] is the radiation temperature t r and the heat transfer coefficient on the body surface h c Therefore, the radiation temperature t r and the heat transfer coefficient h c Further processing is required to identify the above.
[0087] radiant temperature t r may be obtained by measurement using a radiation thermometer (sensor 7), for example. rFor example, the temperature of the space (room temperature) t a、 It may be calculated using a predetermined formula based on the material and structure of the wall.
[0088] Heat transfer coefficient h c is the wind speed in space V a For example, the heat transfer coefficient h c is V a If it is >0.15, it is calculated by [Equation 7], and V a If ≦0.15, it can be calculated using [Equation 8].
[0089]

[0090]

[0091] In this way, the multiple environmental values used in the environmental control system 1 of this embodiment include the temperature of the space and the water vapor pressure of the space, and the multiple environmental values further include the wind speed in the space and the radiant temperature of the walls that make up the space. Furthermore, among the multiple environmental values, the parameter to be controlled is the temperature of the space, and the temperature control value is determined based on the environmental values other than temperature.
[0092] In this embodiment, the radiation temperature t r and the temperature of the space t a Since the control value can be calculated without ignoring the difference between the actual value and the actual value, it is more likely that a comfortable environment can be provided to the user.
[0093] (Modification of Embodiments 1 and 2) The following describes modifications of the first and second embodiments. The following modifications may be implemented in appropriate combination. Unless otherwise specified, the following modifications are applicable to both the first and second embodiments.
[0094] (Variation 1) First, this first modification is similar to the first and second embodiments in that at least one parameter to be controlled includes the temperature of the space. However, it differs from the first and second embodiments in that the user information further includes at least one of information regarding whether the user is sensitive to heat or not and information regarding whether the user is sensitive to cold or not. If the user is sensitive to heat, the derivation unit 23 makes a correction to decrease the control value of the space temperature. On the other hand, if the user is sensitive to cold, the derivation unit 23 makes a correction to increase the control value of the space temperature.
[0095] Information regarding whether the user is sensitive to heat or not and whether the user is sensitive to cold or not is input by the user's operation to the operation unit 35 of the information terminal 3, for example, and is provided to the first acquisition unit 21.
[0096] For example, the temperature control value (set temperature) calculated by [Equation 2] is Te2 (see FIG. 3). When the first acquisition unit 21 acquires information that the user is sensitive to heat, the derivation unit 23 changes the set temperature from Te2 to a temperature C1 that is lower than Te2 by a predetermined value. On the other hand, when the first acquisition unit 21 acquires information that the user is sensitive to cold, the derivation unit 23 changes the set temperature from Te2 to a temperature C2 that is higher than Te2 by a predetermined value.
[0097] According to the present first modification, the set temperature can be corrected depending on whether the user is sensitive to heat or cold, making the space even more comfortable for the user.
[0098] As a further modification of the present modification 1, the correction amount of the control value for the temperature of the space may be increased as the user's sensitivity to heat or cold increases.
[0099] (Variation 2) The controlled parameter is the temperature of the space, t a The controlled parameter is the water vapor pressure P a In the second embodiment, the parameter to be controlled may be the wind speed V a, or the radiation temperature t of the walls that make up the space r In these cases, the second acquisition unit 22 acquires a preset temperature value. The preset temperature value is, for example, the temperature of the space measured by a temperature sensor (sensor 7) or the set temperature of an air conditioner serving as the environmental device 6. The derivation unit 23 can calculate a control value, which is the value of the control target parameter when environmental values other than the control target parameter are fixed, using [Equation 2]. The control unit 24 controls the environmental device 6 based on the control value calculated by the derivation unit 23. For example, the control unit 24 controls a humidifier or a dehumidifier serving as the environmental device 6 to change the set value of humidity as the control target parameter. Furthermore, for example, the control unit 24 controls a ventilation device or an air conditioner serving as the environmental device 6 to change the set value of wind speed as the control target parameter. Furthermore, for example, the control unit 24 controls a floor heating device and a wall heating panel serving as the environmental device 6 to change the set value of radiant temperature as the control target parameter.
[0100] In the second embodiment, the plurality of environmental values include the temperature t a , water vapor pressure P a , wind speed V a , and radiant temperature t r Therefore, two or three of the multiple environmental values may be set as the controlled parameters. In other words, if the number of environmental values is M, two or more but less than M environmental values may be set as the controlled parameters. For example, if the two control parameters are a first control parameter and a second control parameter, the first control parameter may be controlled so that the change in the first control parameter falls within a predetermined range, while the second control parameter may be controlled so as to satisfy a predetermined relationship. To cite a specific example, when the wind speed V a The wind speed V is adjusted so that the change in a While controlling the temperature of the space t a may be controlled.
[0101] (Variation 3) At least one of the clothing information and the bedding information as information about thermal resistance may be a predetermined value. For example, this modification 3 is applied when the environmental control system 1 is used to control environmental devices 6 in a facility such as a hotel where clothing and bedding for a user at bedtime are prepared in advance.
[0102] The thermal resistance of the user corresponding to the thermal resistance of the clothing and bedding that are fixtures of the facility is stored in advance in the storage unit 13 of the environmental control system 1. The first acquisition unit 21 reads out the thermal resistance of the user from the storage unit 13. The derivation unit 23 calculates a control value using the thermal resistance read out from the storage unit 13.
[0103] (Variation 4) The user's metabolic rate used to calculate the control value may be, for example, a value calculated by a body composition meter. When the user measures their metabolic rate using the body composition meter, the body composition meter outputs the metabolic rate as a measurement result to the environmental control system 1, and the derivation unit 23 calculates the control value using the metabolic rate acquired from the body composition meter. Alternatively, the user may input the metabolic rate measured by the body composition meter into the information terminal 3, and the derivation unit 23 may calculate the control value using the metabolic rate input into the information terminal 3.
[0104] (Embodiment 3) An environmental control system 1 according to a third embodiment will be described below. The same components as those in the first embodiment will be denoted by the same reference numerals and will not be described again. The following embodiment may be realized by appropriately combining the modified example of the first embodiment and the second embodiment (including the modified example).
[0105] The environmental control system 1 of this embodiment conducts a questionnaire with the user when the user wakes up. The questionnaire is about the user's thermal sensation. Based on the results of the questionnaire, the environmental control system 1 corrects the control value of the temperature of the space when the user goes to bed. This can help the user sleep better.
[0106] For example, when the derivation unit 23 determines the control value for the temperature of the space, the user's metabolic rate and thermal resistance are referenced, as in the first embodiment. However, due to errors in the metabolic rate and thermal resistance, the control value for the temperature of the space may deviate from the temperature at which the user feels comfortable. Furthermore, due to factors such as the positional relationship between the environmental equipment 6 (such as an air conditioner) and the user, the temperature around the user may locally become lower or higher, and may deviate from the temperature at which the user feels comfortable. Therefore, the environmental control system 1 can provide a space in which the user feels more comfortable by correcting the control value for the temperature of the space.
[0107] First, the configuration of the environmental control system 1 of this embodiment will be described with reference to Fig. 4. Compared to the first embodiment, the processing unit 2 of the environmental control system 1 further includes an input determination unit 27, a correction unit 28, and a notification processing unit 29. Note that these merely indicate functions realized by the processing unit 2, and do not necessarily indicate a substantial configuration.
[0108] The input determination unit 27 determines whether or not a questionnaire should be administered to the user and the contents of the questionnaire based on the implementation status of the bedtime control. The bedtime control is a temperature control of a space that is implemented while the user is sleeping.
[0109] When the input determination unit 27 decides to conduct a survey, the communication unit 12 of the environmental control system 1 notifies the information terminal 3 of the decision made by the input determination unit 27. The information terminal 3 then presents the survey to the user. More specifically, the display unit 34 of the information terminal 3 displays the survey content. The user can respond to the survey by operating the operation unit 35 of the information terminal 3. The communication unit 32 of the information terminal 3 notifies the environmental control system 1 of the survey results.
[0110] The correction unit 28 corrects the control value of the space temperature obtained by the derivation unit 23 based on the results of the questionnaire. The control unit 24 controls the environmental equipment 6 based on the control value corrected by the correction unit 28.
[0111] Furthermore, when a predetermined condition is satisfied, the notification processing unit 29 causes the information terminal 3 to issue a notification urging the user to change at least one of the clothing information and the bedding information. That is, when a predetermined condition is satisfied, the notification processing unit 29 causes the communication unit 12 to transmit information related to the notification to the information terminal 3, and in response, the information terminal 3 notifies the user.
[0112] Various configurations of the environmental control system 1 of this embodiment can be embodied as an environmental control method, a (computer) program, or a non-transitory recording medium on which a program is recorded. That is, in one aspect of the environmental control method, at least one controlled parameter includes the temperature of the space. The environmental control method further includes an input step and a correction step in addition to a first acquisition step, a second acquisition step, a derivation step, and a control step. In the input step, input of thermal sensation information relating to at least one of the user's thermal sensation when going to sleep and the user's thermal sensation when waking up is accepted from the user. In the correction step, the control value of the space temperature calculated in the derivation step is corrected based on the thermal sensation information input in the input step. In the control step, the environmental device 6 is controlled based on the control value of the space temperature corrected in the correction step.
[0113] The environmental control method and environmental control system 1 of this embodiment will be described in further detail below.
[0114] In the derivation step, a control value for the space temperature is calculated so that a predetermined bedtime control is performed on the environmental equipment 6. In the bedtime control, temperature decrease control is performed from a first time t11, and then temperature increase control is performed from a second time t12. In the temperature decrease control, the control value for the space temperature is decreased to a first temperature Ta1. In the temperature increase control, the control value for the space temperature is increased to a second temperature Ta2. The bedtime control is performed when the user is sleeping. For example, the bedtime control is performed during a preset time period. Note that the bedtime control may also be performed at a time other than when the user is sleeping.
[0115] 5A and 5B show an example of bedtime control. Bedtime control begins at a first time t11. Temperature decrease control is control from the first time t11 to time t110. As an example, time t110 is a predetermined time (e.g., 60 minutes) after the first time t11. Temperature increase control is control from a second time t12 to time t140. As an example, the second time t12 is a predetermined time (e.g., 120 minutes) before the user's predetermined scheduled wake-up time t15.
[0116] In this embodiment, the plurality of environmental devices 6 includes an air conditioner. By adjusting the set temperature (control value) of the air conditioner, bedtime control is performed, which involves changing the temperature of the space (measured temperature). The measured temperature is measured by a temperature sensor (sensor 7).
[0117] During the period before the first time t11, the set temperature of the air conditioner is the temperature Ta0 set by the user's operation. Also, during the period before the first time t11, the temperature in the space (measured temperature) is the temperature Ta0. The first time t11 is the time when the user goes to bed.
[0118] The derivation unit 23 calculates a temperature control value (set temperature). More specifically, as in the first embodiment, the derivation unit 23 calculates the set temperature using Equation 2 based on the user's metabolic rate, the user's thermal resistance, and a predetermined value of humidity (water vapor pressure). In FIG. 5A, the set temperature is set to a first temperature Ta1. The first temperature Ta1 is lower than the temperature Ta0.
[0119] By setting the set temperature to the first temperature Ta1, the temperature of the space (measured temperature) decreases over time to the first temperature Ta1. In Fig. 5B, the temperature of the space (measured temperature) reaches the first temperature Ta1 at time t110.
[0120] The set temperature is maintained at the first temperature Ta1 from the first time t11 to the second time t12. At the second time t12, the control unit 24 increases the set temperature. More specifically, the control unit 24 gradually increases the set temperature so that the set temperature reaches the second temperature Ta2 at time t140. In this embodiment, the control unit 24 increases the set temperature discontinuously (in steps) over time. The time t140 is a time before the user's scheduled wake-up time t15. The scheduled wake-up time t15 is a preset time. The second temperature Ta2 is higher than the temperature Ta0.
[0121] Between the second time t12 and time t14, the control unit 24 increases the set temperature in multiple stages. Specifically, the control unit 24 sets the set temperature to Ta_a at the second time t12, then sets the set temperature to Ta_b at time t13, and then sets the set temperature to the second temperature Ta2 at time t14.
[0122] Thereafter, at the scheduled wake-up time t15, the control unit 24 sets the set temperature to temperature Ta0. That is, at the scheduled wake-up time t15, the control unit 24 sets the set temperature to a temperature equal to the set temperature up to bedtime t1. Because the second temperature Ta2, which is the set temperature immediately before the scheduled wake-up time t15, is higher than temperature Ta0, it is possible to reduce the possibility that the user will feel chilly when waking up.
[0123] As an example, each set temperature can be calculated using [Equation 9] to [Equation 12]. If the set temperature of an environmental device 6 such as an air conditioner can be set in increments of a fixed value (for example, 1°C), the set temperature is actually set to the set temperature closest to the value calculated using [Equation 9] to [Equation 12].

[0128] Ta1_init is the first temperature (control value) before correction calculated by the derivation unit 23. The first temperature before correction can be calculated, for example, by [Equation 2]. According to [Equation 2], the first temperature before correction is calculated based on the thermal resistance of the user. When calculating the first temperature before correction, the thermal resistance is calculated using [Equation 5] out of [Equation 5] and [Equation 6]. [Equation 5] is an equation for calculating the thermal resistance of the user when the user is wearing bedding.
[0129] Ta1_adjust is the amount of correction determined from the results of a questionnaire (a questionnaire during sleep, which will be described later).
[0130] Ta2_init is the second temperature (control value) before correction, calculated by the derivation unit 23. The second temperature before correction can be calculated, for example, by [Equation 2]. When calculating the second temperature before correction, the thermal resistance is calculated using [Equation 6] out of [Equation 5] and [Equation 6]. [Equation 6] is an equation for calculating the thermal resistance of a user when the user is not wearing bedding.
[0131] Ta2_adjust is the amount of correction determined from the results of a questionnaire (a morning questionnaire, described later).
[0132] Next, the questionnaire will be described. As described above, the display unit 34 of the information terminal 3 displays the contents of the questionnaire. The user can respond to the questionnaire by operating the operation unit 35 of the information terminal 3.
[0133] The questionnaire may include a sleep questionnaire and a wake-up questionnaire. In the sleep questionnaire, the user answers questions about their thermal sensations while sleeping. In the wake-up questionnaire, the user answers questions about their thermal sensations upon waking up.
[0134] When the user wakes up, the user performs a predetermined operation on the information terminal 3. In response to this, the information terminal 3 notifies the environment controlling system 1 that the user has woken up.
[0135] When the user wakes up, the input determination unit 27 determines whether or not a questionnaire is required, and if the input determination unit 27 determines that a questionnaire is required, the questionnaire is conducted by the information terminal 3.
[0136] Furthermore, the control unit 24 of the environmental control system 1 ends the bedtime control at the scheduled wake-up time t15. If, for example, the above-mentioned predetermined operation is performed on the information terminal 3 while the control unit 24 is performing the bedtime control, the control unit 24 interrupts the bedtime control. Furthermore, for example, if the operating mode of the environmental control system 1 is switched from automatic mode to manual mode by a user operation, the control unit 24 interrupts the bedtime control. In the automatic mode, the derivation unit 23 determines the control values of the environmental equipment 6, such as an air conditioner. In the manual mode, the user inputs the control values of the environmental equipment 6, such as an air conditioner, by operating the operation unit 35 of the information terminal 3.
[0137] The input determination unit 27 determines whether or not a survey is necessary based on the interruption status of the bedtime control. More specifically, when the user wakes up and ends the bedtime control, the input determination unit 27 determines whether or not a survey is necessary based on the time when the bedtime control was interrupted. In other words, the input determination unit 27 determines whether or not a survey is necessary based on the time when the user wakes up.
[0138] For example, if the predetermined operation is performed at a preset scheduled wake-up time t15, the bedtime control ends without interruption, and the input determination unit 27 determines to conduct both the sleep questionnaire and the wake-up questionnaire. Also, if the predetermined operation is performed within a predetermined time from the scheduled wake-up time t15, the input determination unit 27 determines to conduct both the sleep questionnaire and the wake-up questionnaire.
[0139] Furthermore, if the bedtime control is interrupted before the second time t12, the input determination unit 27 conducts only the sleeping questionnaire. However, as will be described later, if the bedtime control is interrupted before time t110, the input determination unit 27 does not conduct either the sleeping questionnaire or the wake-up questionnaire.
[0140] That is, if the bedtime control is interrupted before the second time t12, the input step omits input of information regarding the user's thermal sensation upon waking as thermal sensation information. Then, the input step accepts input of information regarding the user's thermal sensation while sleeping from the user. The user's thermal sensation upon waking corresponds to the thermal sensation under the temperature increase control after the second time t12. By omitting input of the user's thermal sensation upon waking if the bedtime control is interrupted before the second time t12, it is possible to prevent answers unrelated to the temperature increase control from being given.
[0141] When waking up, the user answers a sleep questionnaire. In the sleep questionnaire, the user answers about their thermal sensations while sleeping. In other words, the user answers whether they felt hot, cold, or the temperature was just right while sleeping.
[0142] Table 1 shows an example of the relationship between the response to the sleep questionnaire and the amount of change in the correction amount Ta1_adjust.
[0143] [Table 1]
[0144] The storage unit 13 of the environmental control system 1 stores a data table corresponding to, for example, Table 1. The correction unit 28 refers to the data table and determines a new correction amount Ta1_adjust from the responses to the sleep questionnaire. The new correction amount Ta1_adjust is the sum of the previous correction amount Ta1_adjust and the amount of change determined from Table 1. The initial value of the correction amount Ta1_adjust is 0.
[0145] Therefore, if the sleep questionnaire is completed multiple times, the correction amount Ta1_adjust will be the sum of the multiple changes corresponding to the responses to the multiple sleep questionnaires. For example, if the correction amount Ta1_adjust is 0 and the user responds "it's hot" to the sleep questionnaire twice in a row, the correction amount Ta1_adjust will be -2°C.
[0146] After the correction amount Ta1_adjust is calculated, the corrector 28 corrects the first temperature Ta1_init (set temperature) calculated by the deriver 23 using [Equation 9].
[0147] Furthermore, if the bedtime control is interrupted before time t110 when the measured temperature drops to the first temperature Ta1, the input determination unit 27 does not conduct either the sleeping questionnaire or the wake-up questionnaire. That is, if the bedtime control is interrupted before the space temperature drops to the first temperature Ta1 during the temperature reduction control (from the first time t11 to time t110), the input step is omitted. This makes it possible to prevent responses from being made even when the bedtime control has hardly been performed. Whether the space temperature has dropped to the first temperature Ta1 may be determined by monitoring the measured value of the space temperature, or it may be determined that the space temperature has not dropped to the first temperature Ta1 if the bedtime control is interrupted before time t110.
[0148] Furthermore, if the bedtime control is not interrupted before the second time t12, the input determination unit 27 conducts both the questionnaire during sleep and the questionnaire upon waking up. That is, in this case, in the input step, input of information regarding the user's thermal sensation while sleeping and the user's thermal sensation upon waking up is accepted from the user as thermal sensation information.
[0149] Table 2 shows an example of the relationship between the response to the wake-up questionnaire and the amount of change in the correction amount Ta2_adjust.
[0150] [Table 2]
[0151] The storage unit 13 of the environmental control system 1 stores a data table corresponding to, for example, Table 2. The correction unit 28 refers to the data table and determines a new correction amount Ta2_adjust from the responses to the wake-up questionnaire. The new correction amount Ta2_adjust is the sum of the previous correction amount Ta2_adjust and the amount of change determined from Table 2. The initial value of the correction amount Ta2_adjust is 0.
[0152] Therefore, if the wake-up questionnaire is completed multiple times, the correction amount Ta2_adjust will be the sum of the multiple changes corresponding to the responses to the multiple wake-up questionnaires. For example, if the correction amount Ta2_adjust is 0 and the user responds "it's hot" to the wake-up questionnaire twice in a row, the correction amount Ta2_adjust will be -2°C.
[0153] After the correction amount Ta2_adjust is calculated, the corrector 28 corrects the second temperature Ta2_init (set temperature) calculated by the deriver 23 using [Equation 10].
[0154] Furthermore, the environmental control system 1 may change the range of the correction amounts Ta1_adjust and Ta2_adjust in response to a user input. The range refers to the magnitude of the correction amounts Ta1_adjust and Ta2_adjust. For example, in Table 1 and Table 2, the correction amounts Ta1_adjust and Ta2_adjust are in the range of -1.0°C to +1.0°C. The user may operate the operation unit 35 of the information terminal 3 to change the correction amounts Ta1_adjust and Ta2_adjust to a range of, for example, -5.0°C to +5.0°C.
[0155] As in the first embodiment, the environment control method of this embodiment also includes a thermal resistance deriving step, in which the thermal resistance of the user is calculated based on clothing information about the user's clothes and bedding information about the bedding used by the user.
[0156] The environment control method of this embodiment further includes a notification step, in which a notification is given to prompt a user to change at least one of the clothing information and the bedding information.
[0157] The notification processing unit 29 determines whether or not a predetermined condition is satisfied. If the predetermined condition is satisfied, the notification processing unit 29 causes the communication unit 12 to transmit information related to the notification to the information terminal 3, and in response, the information terminal 3 notifies the user.
[0158] The predetermined condition is that at least one of a first condition and a second condition is satisfied. The first condition is that the absolute value of the correction amount of the control value (set temperature) of the space temperature in the correction step is greater than a threshold value. The threshold value is a preset value. For example, the threshold value is 4°C. The second condition is that the current date is a predetermined date.
[0159] When the first condition is satisfied, that is, when the set temperatures (Ta1_init and Ta2_init in [Equation 9] and [Equation 10]) calculated by the derivation unit 23 are significantly different from the temperature that is comfortable for the user, the information terminal 3 issues the above notification. This can prompt the user to adjust the temperature by changing their clothing and bedding.
[0160] Furthermore, with regard to the second condition, the predetermined date is, for example, a date that corresponds to the time when people change their clothes. For example, the days included in the predetermined periods of April to May and September to October respectively correspond to the predetermined dates. When the second condition is met, that is, when it is time to change their clothes, the information terminal 3 issues the above notification. This can prompt the user to adjust the temperature by changing at least one of their clothes and bedding.
[0161] Here, when at least one of the clothing information and the bedding information is changed, the environmental control system 1 may set the value obtained by multiplying the correction amount by X as the new correction amount. X is a value between 0 and 1. In other words, in this case, the correction amount may be changed according to the following [Equation 13] and [Equation 14]. In [Equation 13], Ta1_adjust is the new correction amount, and Ta1_adjust_before is the immediately preceding correction amount. In [Equation 14], Ta2_adjust is the new correction amount, and Ta2_adjust_before is the immediately preceding correction amount.

[0165] When the user changes at least one of their clothing and bedding, they must reset the correction amount. Therefore, by multiplying the correction amount by X and setting it as the new correction amount, the effect of the correction amount on the set temperature can be reduced, making it easier for the user to determine whether the set temperature before correction was high or low.
[0166] Regarding the environmental control method of this embodiment, the process flow for conducting a questionnaire and correcting the set temperature will be described with reference to Fig. 6. Fig. 6 merely shows one example of the environmental control method, and the order of the processes may be changed as appropriate, and processes may be added or omitted as appropriate.
[0167] At a first time t11, the environmental control system 1 starts bedtime control (step ST11). If the bedtime control is subsequently interrupted by a user operation (step ST12: Yes), the process proceeds to step ST17. On the other hand, if the bedtime control is not interrupted and the end time of the bedtime control arrives (step ST13: Yes), the environmental control system 1 conducts both a wake-up questionnaire and a sleep questionnaire (steps ST14 and ST15). Based on the answers to the questionnaires, the correction unit 28 corrects the set temperature (step ST16).
[0168] Even if the bedtime control is interrupted after the second time t12 (step ST17: No), the environmental control system 1 conducts both the wake-up questionnaire and the sleep questionnaire (steps ST14 and ST15). Based on the answers to the questionnaires, the correction unit 28 corrects the set temperature (step ST16).
[0169] If the bedtime control is interrupted after time t110 before the second time t12 (step ST17: Yes, step ST18: No), the environmental control system 1 conducts only the sleep questionnaire (step ST15). Based on the answers to the questionnaire, the correction unit 28 corrects the set temperature (step ST16).
[0170] If the bedtime control is interrupted before time t110 (step ST18: Yes), the environmental control system 1 does not conduct the survey, and therefore the set temperature is not corrected.
[0171] (Modification of the third embodiment) Below, we will list some modifications of the third embodiment. The following modifications may be implemented in appropriate combination.
[0172] In the third embodiment, when at least one of the clothing information and the bedding information is changed, the environmental control system 1 sets a new correction amount to a value obtained by multiplying the correction amount by X, where X is a value between 0 and 1. Here, X may be a value between 0 and 1. Alternatively, the value of X may be set within a range between 0 and 1. For example, the value of X may be set within a range between 0 and 1 in accordance with a user's operation on the operation unit 35 of the information terminal 3.
[0173] The correction amounts Ta1_adjust and Ta2_adjust may be a common value.
[0174] In the temperature increase control, the set temperature is not limited to increasing discontinuously (in steps) over time as shown in FIG. 5A, but may change continuously as shown in FIG.
[0175] The survey may be conducted at any time other than when the user wakes up.
[0176] The survey does not have to be conducted every day, but may be conducted only when the user wishes, or may be conducted every predetermined number of days, such as once a week.
[0177] In the third embodiment, if the bedtime control is interrupted before the second time t12, the wake-up questionnaire is not conducted. However, the condition for not conducting the wake-up questionnaire is not limited to this. For example, if the bedtime control is interrupted before a predetermined first intermediate time, the wake-up questionnaire may not be conducted. The first intermediate time is a time between the second time t12 and the scheduled wake-up time t15.
[0178] In the third embodiment, if the bedtime control is interrupted before time t110, the sleeping questionnaire and the waking-up questionnaire are not conducted. However, the conditions for not conducting the sleeping questionnaire and the waking-up questionnaire are not limited to this. For example, if the bedtime control is interrupted before a predetermined second intermediate time, the sleeping questionnaire and the waking-up questionnaire may not be conducted. The second intermediate time is a time between the first time t11 and the second time t12.
[0179] In addition to being corrected based on the sleep questionnaire and the wake-up questionnaire, the set temperature may also be corrected based on at least one of information regarding whether the user is sensitive to heat or not and information regarding whether the user is sensitive to cold or not, as in variant example 1 of embodiments 1 and 2.
[0180] (Other variations) Other variations of the first to third embodiments are listed below. The following variations may be implemented in appropriate combinations. The following variations may also be implemented in appropriate combinations with the above-described variations.
[0181] The environmental control system 1 may communicate with a plurality of environmental devices 6 and a plurality of sensors 7 without going through the control unit 5 and the gateway 4. Furthermore, at least some of the functions of the control unit 5 may be provided in the environmental control system 1.

For example, the derivation unit 23 may increase or decrease the set temperature (control value) of the environmental device 6, such as an air conditioner, the greater the distance between the user and the environmental device 6.
[0184] When calculating the user's metabolic rate at the time of waking up, the metabolic rate derivation unit 25 may correct the metabolic rate according to the user's activity. Information on the user's activity is input, for example, by the user operating the operation unit 35 of the information terminal 3, and acquired by the first acquisition unit 21. Examples of the user's activity include resting, office work, walking, carrying things, cooking, cleaning, and sports.
[0185] The configuration of the environmental control system 1 may be realized by an environmental control method. The environmental control method according to one embodiment controls at least one controlled parameter, which is a part of multiple environmental values related to the environment of a space. The multiple environmental values include the temperature and water vapor pressure of the space. The environmental control method includes a first acquisition step, a second acquisition step, a derivation step, and a control step. In the first acquisition step, user information including information on the user's metabolic rate and information on the user's thermal resistance is acquired.

In the derivation step, at least one control value is calculated based on the user information acquired in the first acquisition step and the default values of the one or more environmental values acquired in the second acquisition step. The at least one control value is a value of the at least one controlled parameter when a predetermined relationship exists between the user information, the default values of the one or more environmental values, and the at least one controlled parameter. In the control step, the environmental device 6 is controlled based on the at least one control value calculated in the derivation step. The environmental device 6 adjusts at least one controlled parameter of the space.
[0186] In an environmental control method according to one aspect, at least one controlled parameter includes a temperature of the space. The user information further includes at least one of information regarding whether the user is sensitive to heat or not and information regarding whether the user is sensitive to cold or not. In the deriving step, if the user is sensitive to heat, a correction is made to decrease the control value of the space temperature, and if the user is sensitive to cold, a correction is made to increase the control value of the space temperature.

[0189] A program according to one aspect is a program for causing one or more processors of a computer system to execute the environmental control method according to any of the above aspects. The program may be recorded on a computer-readable non-transitory recording medium.
[0190] The environmental control system 1 of the present disclosure includes a computer system. The computer system is primarily composed of a processor and memory as hardware. At least a portion of the functions of the environmental control system 1 of the present disclosure are realized by the processor executing a program stored in the computer system's memory. The program may be pre-stored in the computer system's memory, provided via a telecommunications line, or provided on a non-transitory recording medium readable by the computer system, such as a memory card, optical disk, or hard disk drive. The processor of the computer system is composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits, such as ICs and LSIs, are referred to by different names depending on the degree of integration, and include integrated circuits called system LSIs, very large-scale integrations (VLSIs), and ultra-large-scale integrations (ULSIs). Furthermore, field-programmable gate arrays (FPGAs), which are programmable after the LSI is manufactured, or logic devices that allow the reconfiguration of internal connections or internal circuit partitions of the LSI, can also be used as processors. The electronic circuits may be integrated into one chip or distributed across multiple chips. The chips may be integrated into one device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.
[0191] Furthermore, it is not essential for the environmental control system 1 that multiple functions in the environmental control system 1 are integrated into one device, and the components of the environmental control system 1 may be distributed across multiple devices. Furthermore, at least some of the functions of the environmental control system 1, for example, at least some of the functions of the derivation unit 23, may be realized by the cloud (cloud computing) or the like.
[0192] Conversely, in the embodiment, functions distributed among multiple devices may be consolidated into one device. For example, functions distributed between the environmental control system 1 and the information terminal 3 may be consolidated into one device.

The multiple environmental values include the temperature and water vapor pressure of the space. The environmental control system (1) includes a first acquisition unit (21), a second acquisition unit (22), a derivation unit (23), and a control unit (24).

[0195] According to the above configuration, the environment of the space can be controlled so that the predetermined relationship is satisfied. This makes it possible to maintain the comfort of the space. Since the predetermined relationship is related to user information, it is more likely that an environment that each user finds comfortable can be provided, taking into account differences in how each user perceives a certain environment. For example, it is possible to provide an environment that makes it easier for the user to get a good night's sleep.
[0196] In addition, in the environmental control system (1) according to the second aspect, in the first aspect, the plurality of environmental values further includes a wind speed in the space and a radiation temperature of a wall that constitutes the space.

[0199] According to the above configuration, the temperature of the space can be corrected depending on whether the user is sensitive to heat or cold, making the space even more comfortable for the user.

In the second acquisition step, default values of one or more environmental values excluding at least one controlled parameter are acquired from the multiple environmental values. In the derivation step, at least one control value is calculated based on the user information acquired in the first acquisition step and the default values of the one or more environmental values acquired in the second acquisition step. The at least one control value is a value of the at least one controlled parameter when the user information, the default values of the one or more environmental values, and the at least one controlled parameter have a predetermined relationship. In the control step, an environmental device (6) is controlled based on the at least one control value calculated in the derivation step. The environmental device (6) adjusts the at least one controlled parameter of the space.
[0208] According to the above configuration, it is possible to provide an environment that each user finds comfortable, in response to differences in how each user feels about a certain environment.

[0210] According to the above configuration, the temperature of the space can be corrected depending on whether the user is sensitive to heat or cold, making the space even more comfortable for the user.
[0211] Furthermore, the environmental control method according to a ninth aspect is the seventh or eighth aspect, further comprising a metabolic rate deriving step of determining the metabolic rate of the user based on physical information of the user.

[0215] In addition, an environmental control method according to an eleventh aspect is any one of the seventh to ninth aspects, wherein at least one parameter to be controlled includes a temperature of the space. The environmental control method further includes an input step and a correction step. In the input step, input of thermal sensation information relating to at least one of the user's thermal sensation while sleeping and the user's thermal sensation upon waking up is accepted from the user. In the correction step, the control value of the space temperature calculated in the derivation step is corrected based on the thermal sensation information input in the input step. In the control step, the environmental equipment (6) is controlled based on the control value of the space temperature corrected in the correction step.
[0216] According to the above configuration, it is possible to provide a space in which the user feels more comfortable.
[0217] In addition, in an environmental control method according to a twelfth aspect, in the eleventh aspect, in the derivation step, a control value for the space temperature is calculated so as to perform predetermined bedtime control on the environmental device (6). In the bedtime control, temperature decrease control is performed to decrease the control value of the space temperature to a first temperature (Ta1) from a first time (t11), and then temperature increase control is performed to increase the control value of the space temperature to a second temperature (Ta2) from a second time (t12).
[0218] According to the above configuration, it is possible to promote good sleep for the user.
[0219] In addition, in the environmental control method of the 13th aspect, in the 12th aspect, if the bedtime control is interrupted before the second time (t12), the input step omits inputting information regarding the user's thermal sensation upon waking up as thermal sensation information.
[0220] According to the above configuration, it is possible to prevent a user from giving an answer about the thermal sensation that is unrelated to the control that has actually been performed.
