[0007] An air conditioning control suggestion method according to one aspect of the present disclosure includes a control step and a suggestion step. In the control step, a control process is performed on an air conditioning unit that performs air conditioning processing. The air conditioning process is a process for adjusting one or more physical quantities including at least a temperature of the air in a room, and the control process includes a setting process. The setting process is a process for setting a target temperature for the air conditioning process during a sleeping period. The sleeping period is a period during which multiple users sleep in the room. In the suggestion step, suggestion information is acquired to suggest to each of the multiple users a heat resistance member that covers the bodies of the multiple users during the sleeping period and prevents heat dissipation from the bodies to the room, such that each of the multiple users' thermal sensation evaluation values ​​at the target temperature satisfy a comfort condition. Then, in the suggestion step, one or more pieces of suggestion information corresponding to one or more users are output via an output unit from among the multiple pieces of suggestion information corresponding to the multiple users.

[0010] (1) Overview First, the overview and main parts of the present disclosure will be described with reference to FIGS. 1 and 11.

[0011] (1-1) Air Conditioning Control Proposal System An air conditioning control proposal system 100 according to an embodiment of the present disclosure includes a control unit 121 and a proposal unit 122.

[0012] (1-1-1) Means for realizing the air conditioning control proposal system In this embodiment, as shown in Fig. 1, the air conditioning equipment 10 includes an air conditioning unit 101, and the control device 1 includes a control unit 121 and a proposal unit 122. In other words, the air conditioning control proposal system 100 in this embodiment is realized by the air conditioning equipment 10 and the control device 1.

[0013] The control device 1 is capable of communicating with the air conditioning equipment 10. Furthermore, the air conditioning control proposal system 100 or the control device 1 constituting the system is capable of communicating with each of a plurality of terminals 20.

[0014] Each of the air conditioning equipment 10, the control device 1, and the multiple terminals 20 has a processor, a memory, and a communication module. Each of the multiple terminals 20 further has an input device such as a touch panel and an output device such as a display. The processor operates based on programs and the like in the memory (and further cooperates with the communication module and the like), thereby realizing the functions of each of the air conditioning equipment 10, the control device 1, and the multiple terminals 20.

[0015] (1-1-2) Modified Examples of Means for Implementing the Air Conditioning Control Proposal System However, for example, the air conditioning equipment 10 may be equipped with the air conditioning unit 101, the control unit 121, and the proposal unit 122. In other words, the air conditioning control proposal system 100 can be implemented by the air conditioning equipment 10 alone. In this case, it is preferable that the air conditioning equipment 10 has an input device such as a touch panel and an output device such as a display.

[0016] (1-1-3) Air Conditioning Equipment The air conditioning equipment 10 is, for example, an air conditioner (hereinafter abbreviated as air conditioner) as shown in Fig. 11, preferably an air conditioner with a dehumidifying function, but may also be an air conditioner without a dehumidifying function. Alternatively, the air conditioning equipment 10 may be a combination of an air conditioner without a dehumidifying function with a humidifier and / or a dehumidifier, or may further include an electric fan.

[0017] (1-1-4) Control Device The control device 1 is, for example, a remote control attached to the air conditioning equipment 10, but may also be a multi-remote control that can control multiple devices including the air conditioning equipment 10 (air conditioning equipment 10 and lighting fixtures (not shown), etc.).

[0018] The control device 1 is connected to the air conditioning equipment 10 so as to be able to communicate with them via wired or wireless communication. The wireless communication here is, for example, infrared communication or short-range wireless communication such as Bluetooth (registered trademark), but may also be communication via a network such as a wireless LAN.

[0019] (1-2) Control Unit The control unit 121 controls the air conditioning unit 101 that performs air conditioning processing.

[0020] (1-3) Air Conditioning Process Air conditioning process is a process for adjusting one or more physical quantities including at least the temperature (current temperature) of the air in the room.

[0021] (1-3-1) "One or more physical quantities" to be subjected to air conditioning treatment In this embodiment, the one or more physical quantities to be subjected to air conditioning treatment further include humidity. The one or more physical quantities may further include wind speed. The one or more physical quantities are detected by an environmental sensor 21 arranged in the room.

[0022] (1-3-2) Environmental Sensor The environmental sensor 21 in this embodiment is a temperature and humidity sensor, but may be a temperature sensor or a multi-sensor including a temperature sensor, a humidity sensor, a wind speed sensor, a radiation temperature sensor, etc. Note that the environmental sensor 21 in the present disclosure is separate from the air conditioning equipment 10 and the control device 1, but may be built into either the air conditioning equipment 10 or the control device 1.

[0023] (1-4) Control Processing The control processing includes a setting processing. Note that the control processing may further include, for example, a period determination processing and an evaluation processing (both of which will be described later).

[0024] (1-4-1) Setting Process The setting process is a process for setting a target temperature for air conditioning during the sleeping period.

[0025] (1-4-2) Sleeping Period A sleeping period is a period during which multiple users sleep in a room.

[0026] (1-4-2a) Method for Determining Sleeping Periods In this embodiment, the wake-up time or sleeping duration of each of multiple users (hereinafter simply referred to as "multiple users") sleeping in a single room (hereinafter sometimes referred to as "each user") is registered in advance by the operation of each user. Meanwhile, each user's bedtime is detected by a sleep sensor 22 arranged in association with each user. Then, based on the multiple bedtimes corresponding to the multiple users, the start time of the sleeping period is determined. Furthermore, based on the multiple wake-up times corresponding to the multiple users, the end time of the sleeping period is determined.

[0027] (1-4-2b) Sleep Sensor The sleep sensor 22 is, for example, a pressure sensor, a heart rate sensor, an acceleration sensor, etc. The pressure sensor is provided, for example, in the mattress 202b, and outputs a signal corresponding to a change in pressure caused by the user going to bed or waking up. The control unit 121 can detect the user going to bed and waking up based on the output signal of the pressure sensor.

[0028] The heart rate sensor is attached to the user's arm, for example, and outputs a signal corresponding to the heart rate. The control unit 121 can detect changes in the heart rate, and thus falling asleep and waking up, based on the output signal from the heart rate sensor.

[0029] The acceleration sensor is attached to the user's arm, for example, and outputs a signal corresponding to the movement of the arm. Based on the output signal of the acceleration sensor, the control unit 121 can detect changes in movement, and therefore, falling asleep, waking up, and the like.

[0030] (1-4-2c) Modified Example of Method for Determining Sleeping Period Both the bedtime and the wake-up time may be automatically acquired based on the output of the sleep sensor 22. Alternatively, sleeping period specification information specifying the sleeping period may be registered in advance by a single user. The sleeping period information may be a set of a start time and an end time, or a set of a start time and a period length.

[0031] (1-4-3) Target Temperature The target temperature is, for example, a set temperature based on a user operation, but may also be a calculated or estimated temperature by the control unit 121. The operation is usually an operation on the terminal 20.

[0032] (1-4-4) Terminal The terminal 20 is, for example, a mobile terminal such as a smartphone or tablet terminal, and is carried by each of multiple users. However, the terminal 20 may also be a fixed terminal such as a personal computer. A fixed terminal may be shared by multiple users.

[0033] The terminal 20 is connected to the air conditioning control proposal system 100 (in this embodiment, the control device 1) so as to be able to communicate wirelessly. The wireless communication here is, for example, short-range wireless communication such as Bluetooth (registered trademark), but may also be communication via a network such as a wireless LAN.

[0034] (1-5) Proposal Unit The proposal unit 122 acquires proposal information for proposing to each of a plurality of users a heat-resistance member 200 that covers the body of each of the plurality of users during a sleeping period and prevents heat from radiating from the body to the room, so that the evaluation value related to the thermal sensation of each of the plurality of users satisfies the comfort condition at the target temperature set by the control unit 121. Then, the proposal unit 122 outputs, via the output unit 13, one or more pieces of proposal information corresponding to one or more users out of the plurality of pieces of proposal information corresponding to the plurality of users.

[0035] (1-5-1) Thermal Sensation Thermal sensation is a sensation related to warmth or cold that a user feels, such as comfortable, cold, hot, etc. A thermal sensation is comfortable (for example, PMV = 0) when the metabolic heat production in the body (described later) is equal to the amount of heat released to the outside of the body.

[0036] (1-5-2) Evaluation Value The evaluation value is a value obtained by evaluating the user's thermal sensation based on a predetermined standard.

[0037] (1-5-2a) Evaluation Value Based on PMV In this embodiment, the thermal sensation is an evaluation value based on PMV (Predicted Mean Vote). The evaluation value based on PMV is, for example, a seven-level value ranging from −3 to +3 (hereinafter, referred to as “PMV=0”).

[0038] PMV = 0 corresponds to "comfortable", PMV = -1 corresponds to "slightly cool", PMV = -2 corresponds to "cool", PMV = -3 corresponds to "cold", PMV = +1 corresponds to "slightly warm", PMV = +2 corresponds to "warm", PMV = +3 corresponds to "hot".

[0039] (1-5-3) Comfort Conditions Comfort conditions are conditions that make a user feel comfortable. For example, the comfort condition is "PMV=0", but it may also be "-1≦PMV≦+1", etc.

[0040] (1-5-4) Heat Dissipation In this embodiment, heat dissipation refers to the transfer of heat from the user's body to the room. Heat dissipation includes, for example, heat dissipation by convection and heat dissipation by radiation.

[0041] (1-5-5) Thermal Resistance Member The thermal resistance member 200 is a member that prevents the transfer of heat (i.e., has thermal resistance), and is, for example, clothing 201 (short-sleeved jacket and long-sleeved jacket, shorts and long pants) and bedding 202 (a comforter 202a and a mattress 202b, etc.).

[0042] (1-5-6) Proposal Information The proposal information is, for example, information indicating a combination of the type and usage mode of the heat resistance member 200 .

[0043] (1-6) Output Unit The output is usually a transmission to the terminal 20. However, the output may also be, for example, a display on a display in the control device 1 or storage in a storage medium.

[0044] The output unit 13 in this embodiment transmits one or more pieces of proposal information acquired by the proposal unit 122 to one or more terminals 20 corresponding to one or more users.

[0045] According to this aspect, by proposing to each of a plurality of users a thermal resistance member 200 whose evaluation value regarding the thermal sensation of each of the users satisfies the comfort conditions when air conditioning processing is performed during the sleeping period and the air temperature reaches the target temperature, it is possible to make each of the multiple users sleeping in one room more comfortable.

[0046] (2) Details Next, details of the air conditioning control proposal system 100 will be described using Figure 1 and Figures 11 to 14. Note that, in the following, descriptions of matters that have already been mentioned will be omitted or simplified.

[0047] 1 , the air conditioning control proposal system 100 of this embodiment includes air conditioning equipment 10 and a control device 1. The air conditioning equipment 10 includes an air conditioning unit 101. The control device 1 includes a reception unit 11, a processing unit 12, and an output unit 13.

[0048] The reception unit 11 receives various types of information. The reception by the reception unit 11 may be, for example, reception from the terminal 20, but may also be reception of information input via an input device such as a touch panel. The various types of information received by the reception unit 11 will be described as appropriate.

[0049] The processing unit 12 performs various types of processing, such as processing by the control unit 121, processing by the proposing unit 122, and processing by the correcting unit 123. The processing unit 12 also performs various types of judgment processing, which will be explained in the flowcharts.

[0050] The output unit 13 outputs various types of information. The various types of information include, for example, proposal information. The output by the output unit 13 is, for example, transmission to the terminal 20, but may also be display on a display, writing to a recording medium such as a memory card, etc.

[0051] The processing unit 12 includes a control unit 121, a proposing unit 122, and a correcting unit 123. The components of the proposing unit 122 will be described later. The correcting unit 123 will also be described later.

[0052] The air conditioning equipment 10 and the control device 1 are placed in a room (a bedroom) where multiple users (e.g., two users A and B) sleep, as shown in Fig. 11. An environmental sensor 21 is placed in the room. The environmental sensor 21 is capable of detecting temperature and humidity.

[0053] Additionally, a plurality of (e.g., two) sleep sensors 22 are arranged in the room in association with a plurality of users (e.g., two users A and B). The sleep sensors 22 are attached to the user's body or clothing 201, or arranged in the user's bedding 202 (e.g., under the mattress 202b).

[0054] (2-1) Details of Proposal Unit As shown in FIG. 1, the proposal unit 122 includes a first thermal resistance acquisition unit 122a, a second thermal resistance acquisition unit 122b, and a proposal acquisition unit 122c.

[0055] (2-1-1) First Thermal Resistance Acquisition Unit The first thermal resistance acquisition unit 122a acquires a first total thermal resistance value for each of multiple users (hereinafter simply referred to as "multiple users") sleeping in a single room, such as a bedroom in Figure 11.

[0056] The first thermal resistance acquisition unit 122a calculates the first total thermal resistance value using, for example, user information, thermal resistance information, and coefficient information (all of which will be described later) stored in the memory. Alternatively, a pre-calculated first total thermal resistance value may be stored in the memory, and the first thermal resistance acquisition unit 122a may acquire the first total thermal resistance value from the memory.

[0057] (2-1-1a) First Overall Thermal Resistance Value The first overall thermal resistance value is a thermal resistance value calculated based on the combination of the type and usage mode of the thermal resistance member 200 (hereinafter, sometimes simply referred to as "combination").

[0058] (2-1-1b) Types of Heat Resistance Members The types of heat resistance members 200 in this embodiment are clothing 201 and bedding 202.

[0059] (2-1-1c) Types of Clothing The types of clothing 201 are, for example, a short-sleeved jacket, a long-sleeved jacket, shorts, and long pants. The types of clothing 201 may also be, for example, sleepwear, underwear, or a yukata.

[0060] (2-1-1d) Types of Bedding The types of bedding 202 in this embodiment are a comforter 202a and a mattress 202b. The types of comforter 202a are comforter 1 (e.g., thick) and comforter 2 (e.g., thin). The types of mattress 202b are mattress 1 (e.g., medium thickness) and mattress 2 (e.g., thick). Note that mattress 1 may be a mattress placed on a tatami mat, and mattress 2 may be a mattress for a bed, etc.

[0061] (2-1-1e) Usage The usage of the heat resistance member 200 is, for example, the way in which the comforter 202a is put on (hereinafter, simply referred to as "how to put on the comforter" or "how to put on"), and the sleeping position on the mattress 202b (hereinafter, "sleeping position").

[0062] (2-1-1f) How to put on a futon There are seven ways to put on a futon, for example, as shown in Figure 12, such as ways a to g. Way a is a way of putting on a futon that covers all parts of the body except the head. Way b is a way of putting on a futon that covers all parts of the body except the head and arms. Way c is a way of putting on a futon that covers all parts of the body except the head and legs. Way d is a way of putting on a futon that covers all parts of the body except the head, arms, and legs (hereinafter referred to as the "torso"). Way e is a way of putting on a futon that covers only the legs. Way f is a way of putting on a futon that covers only part of the torso. Way g is a way of putting on a futon that does not cover any parts of the body.

[0063] (2-1-1g) Sleeping Position There are three types of sleeping positions on the mattress 202b: supine position, lateral position, and prone position.

[0064] (2-1-1h) Combinations A combination of type and usage mode is, for example, a combination of the "type" of the heat-resistance member 200, where the type of clothing 201 is "short sleeves" and "shorts," the type of bedding 202 is "duvet 1" and "mattress 2," and the "usage mode" is where the duvet is placed "duvet position a" and the sleeping position is "supine position." Note that, hereinafter, such a combination may be written as, for example, "{(short sleeves, shorts), (duvet 1, mattress 2), (duvet position a, supine position)}."

[0065] (2-1-2) Second Thermal Resistance Acquisition Unit The second thermal resistance acquisition unit 122b acquires a second total thermal resistance value for each of a plurality of users.

[0066] (2-1-2a) Second total thermal resistance value The second total thermal resistance value is a thermal resistance value such that the evaluation value satisfies the comfort condition when the air temperature is adjusted to the target temperature in an evaluation process that evaluates the thermal sensation based at least on the metabolic heat production, the thermal resistance value of the thermal resistance member 200, and one or more physical quantities including the air temperature, and obtains an evaluation value.

[0067] (2-1-2b) Metabolic Heat Production The metabolic heat production is the amount of metabolic heat (metabolic rate) produced in the user's body. In this embodiment, the metabolic rate is the basal metabolic rate, which is calculated from, for example, height, weight, gender, etc.

[0068] (2-1-2c) "One or more physical quantities" used in the evaluation process The "one or more physical quantities" used in the evaluation process are usually the same as the "one or more physical quantities" that are the target of the air conditioning process (for example, temperature and humidity). However, in addition to the "one or more physical quantities" that are the target of the air conditioning process, the evaluation process may also take into account other physical quantities (for example, wind speed, radiant temperature, etc. when the target of the air conditioning process is temperature and humidity).

[0069] (2-1-2d) Evaluation Process The evaluation process is a process for evaluating the user's thermal sensation based on at least one physical quantity including, for example, the metabolic heat production, the thermal resistance value of the thermal resistance member 200, and the air temperature, and obtaining an evaluation value.

[0070] (2-1-2e) Function for Evaluation Process In the evaluation process of this embodiment, an evaluation value is obtained using a function. The function is a function that uses at least metabolic heat production, thermal resistance, temperature, and humidity as parameters. Such a function is, for example, a function based on PMV, and is expressed as PMV=f(M, I, T, H), where M is metabolic heat production, I is thermal resistance, T is temperature, and H is humidity.

[0071] The parameters of the function may further include physical quantities other than the temperature and humidity (for example, wind speed, radiation temperature).

[0072] (2-1-3) Proposal Acquisition Unit The proposal acquisition unit 122c acquires proposal information regarding a new combination that satisfies the matching condition for one or more users among a plurality of users whose first total thermal resistance value does not satisfy the matching condition with the second total thermal resistance value, and outputs one or more pieces of proposal information corresponding to the one or more users via the output unit 13.

[0073] For example, multiple pieces of proposal information are stored in advance in memory, each of which is associated with a difference (e.g., 1, 2, 3, etc.) between the first total thermal resistance value and the second total thermal resistance value, and the combinations are changed so that the first total thermal resistance value and the second total thermal resistance value satisfy the matching condition, and the proposal acquisition unit 122c may select from the memory proposal information that satisfies the matching condition for the difference between the first total thermal resistance value and the second total thermal resistance value.

[0074] (2-1-3a) Matching Condition The matching condition is a condition under which it is determined that the first total thermal resistance value and the second total thermal resistance value match.

[0075] The matching condition in this embodiment is that the difference between the first total thermal resistance value and the second total thermal resistance value is less than a threshold value (this also includes the case where the first total thermal resistance value and the second total thermal resistance value are the same).

[0076] (2-1-3b) Proposal Information The proposal information may be, for example, information indicating the “combination” of the proposed item (for example, text information indicating the combination “short sleeves and shorts, comforter 1 and mattress 2, comforter style a and supine position,” or image information such as an icon).

[0077] (2-1-3c) Proposal Receiving Screen Alternatively, the proposal information may be, for example, a proposal receiving screen as shown in Fig. 13. The proposal receiving screen is a screen for proposing combinations and receiving the results of judgments on the proposals.

[0078] This suggestion reception screen includes four types of clothing 201 ("short sleeves," "long sleeves," "shorts," and "long pants"), four types of bedding 202 ("comforter 1," "comforter 2," "mattress 1," and "mattress 2"), and seven ways of putting on a futon ("way a" to "way g").

[0079] In addition, the suggestion reception screen further includes four check boxes corresponding to the above four types of clothing 201, four check boxes corresponding to the above four types of bedding 202, and seven check boxes corresponding to the above seven ways of putting on a futon.

[0080] On such a proposal reception screen, a combination of type and mode with a check mark in the corresponding check box indicates a proposal target.

[0081] The proposal acceptance screen also includes a character string such as an inquiry "What do you think of the proposal?" to accept the user's judgment on the proposal, and a response such as "OK," as well as a check box associated with the character string.

[0082] Furthermore, the proposal acceptance screen further includes strings such as "If revisions are necessary, please check the resubmission proposal after changing the checkbox of the above proposal" and "Recalculate" to accept revisions to the proposal content, as well as check boxes corresponding to the strings.

[0083] For example, if the checkbox corresponding to "recalculate" is checked, a new combination is obtained.

[0084] For example, the combination "{(short sleeves, shorts), (comforter 1, mattress 2), (covering style a, supine position)}" described above can be changed to a new combination, such as "{(short sleeves, long pants), (comforter 2, mattress 2), (covering style a, supine position)}." The new combination is then reflected on the proposal reception screen.

[0085] In this way, by comparing the first total thermal resistance value based on the combination of the type and usage mode of the thermal resistance member 200 with the second total thermal resistance value whose evaluation value at the target temperature satisfies the comfort conditions, new combinations can be proposed, thereby making it possible to improve the comfort of each user without obtaining an evaluation value.

[0086] (2-1-4) Calculation of the first total thermal resistance value In detail, the first thermal resistance acquisition unit 122a calculates the first total thermal resistance value for each of multiple users using thermal resistance information and coefficient information based on user information including type information regarding the type of thermal resistance member 200 and mode information regarding the usage mode.

[0087] (2-1-4a) User Information User information is information about a user. The user information is stored in advance in a memory based on the user's operation.

[0088] The user information includes type information and mode information, which indicate the type and mode of use of the heat resistance member 200 used by the user during sleep.

[0089] The user information typically includes a user identifier for identifying the user in addition to type information and mode information. The user information in this embodiment further includes metabolism-related information, which will be described later.

[0090] The user information may further include information for identifying the user's sleep period. The information for identifying the sleep period may be, for example, a set of a bedtime and a wake-up time, but may also be the sleep duration or the wake-up time.

[0091] (2-1-4b) Type Information: Clothing Type Information and Bedding Type Information Type information is information about the type of the heat resistance member 200. In this embodiment, the type information includes clothing type information, which is type information about the clothing 201, and bedding type information, which is type information about the bedding 202. Examples of clothing type information include "short sleeves," "long sleeves," "shorts," and "long pants."

[0092] The bedding type information includes comforter type information, which is type information about the comforter 202a, and mattress type information, which is type information about the mattress 202b. The comforter type information is, for example, "comforter 1" or "comforter 2," and the mattress type information is, for example, "mattress 1" or "mattress 2."

[0093] (2-1-4c) Behavior Information: How to Use the Comforter and Sleeping Position Information The behavior information is information related to the manner of use of the heat resistance member 200. In this embodiment, the behavior information includes how to use the comforter 201, which is information related to how the comforter 201 is used, and sleeping position information, which is information related to the sleeping position relative to the mattress 202.

[0094] The sitting style information includes, for example, "sit style a" to "sit style g." The sleeping position information includes, for example, "supine position," "side position," "face down," etc.

[0095] (2-1-4d) Thermal Resistance Information: Clothing Thermal Resistance Information and Bedding Thermal Resistance Values ​​Thermal resistance information is information relating to the thermal resistance values ​​of various thermal resistance members 200. The thermal resistance information in this embodiment includes clothing thermal resistance information, which is information relating to the thermal resistance values ​​of various clothing 201, and bedding thermal resistance information, which is information relating to the thermal resistance values ​​of various bedding 202.

[0096] Clothing thermal resistance information is a set of pairs of clothing type information and clothing thermal resistance values. Clothing thermal resistance values ​​are the thermal resistance values ​​of clothing 201 corresponding to the clothing type information. In this embodiment, the clothing thermal resistance information includes, for example, a pair "(short sleeves, R1)" of clothing type information "short sleeves" and clothing thermal resistance value "R1," a pair "(long sleeves, R2)" of clothing type information "long sleeves" and clothing thermal resistance value "R2," a pair "(shorts, R3)" of clothing type information "shorts" and clothing thermal resistance value "R3," and a pair "(long pants, R4)" of clothing type information "long pants" and clothing thermal resistance value "R4" (thermal resistance values ​​are measured in clo).

[0097]

[0098] The bedding thermal resistance information is a set of pairs of bedding type information and bedding thermal resistance values. The bedding thermal resistance values ​​are the thermal resistance values ​​of the bedding 202 corresponding to the bedding type information. For example, as shown in Table 2, the bedding thermal information in this embodiment includes a pair "(Duvet 1, B1)" of bedding type information "Duvet 2" and bedding thermal resistance value "B2", a pair "(Duvet 2, B2)" of bedding type information "Mattress 1" and bedding thermal resistance value "M1", a pair "(Mattress 1, M1)" of bedding type information "Mattress 2" and bedding thermal resistance value "M2" (thermal resistance values ​​are measured in clo).

[0099]

[0100] (2-1-4e) Type Information Included in User Information Type information included in user information includes clothing type information and bedding type information regarding the clothing 201 and bedding 202 used by the user during the sleeping period.

[0101] (2-1-4f) Coefficient Information: First Coefficient Information and Second Coefficient Information The coefficient information is information relating to a coefficient that is multiplied by the thermal resistance value of the thermal resistance member 200 and that corresponds to the aspect information of the thermal resistance member 200. The coefficient information in this embodiment includes first coefficient information and second coefficient information.

[0102] The first coefficient information is a set of pairs of multiplication information and first coefficients. For example, as shown in Table 3, the first coefficient information in this embodiment includes a pair "(a, Ka)" of multiplication information "multiplication a" and a first coefficient "Ka," a pair "(b, Kb)" of multiplication information "multiplication b" and a first coefficient "Kb," and a pair "(g, Kg)" of multiplication information "multiplication g" and a first coefficient "Kg."

[0103]

[0104] The second coefficient information is a set of pairs of sleeping position information and second coefficients. For example, as shown in Table 4, the second coefficient information in this embodiment includes a pair "(supine, Ks)" of sleeping position information "supine" and the second coefficient "Ks," a pair "(lateral, Kl)" of sleeping position information "lateral" and the second coefficient "Kl," and a pair "(prone, Kp)" of sleeping position information "prone" and the second coefficient "Kp."

[0105]

[0106] (2-1-4g) Method for calculating the first total thermal resistance value If the first total thermal resistance value is I1, the thermal resistance value of the clothing 201 is R, the thermal resistance value of the comforter 202 is B, the thermal resistance value of the mattress is M, the first coefficient is K1, and the second coefficient is K2, the first total thermal resistance value is calculated using the following formula (Formula 1): I1 = R + (K1 x B) + (K2 x M) ... (Formula 1)

[0107] That is, the first thermal resistance acquisition unit 122a acquires, for each of a plurality of users, the clothing thermal resistance value R paired with the clothing type information included in the user information using the clothing thermal resistance information. For example, if the clothing type information included in the user information corresponding to user A is "short sleeves," the clothing thermal resistance value R1 paired with "short sleeves" is acquired using the clothing thermal resistance information in Table 1.

[0108] Furthermore, the first thermal resistance acquisition unit 122a uses the bedding thermal resistance information to acquire the bedding thermal resistance value paired with the bedding type information included in the user information (i.e., the bedding thermal resistance value B paired with the comforter type information and the bedding thermal resistance value M paired with the mattress type information). For example, if the comforter type information included in the user information corresponding to user A is "comforter 1" and the mattress type information is "mattress 2," the bedding thermal resistance value B1 paired with "comforter 1" and the bedding thermal resistance value M2 paired with "mattress 2" are acquired using the bedding thermal resistance information in Table 2.

[0109] Next, the first thermal resistance acquisition unit 122a uses the first coefficient information to acquire a first coefficient K1 paired with the wearing style information included in the user information for each of the multiple users. Also, the first thermal resistance acquisition unit 122a uses the second coefficient information to acquire a second coefficient K2 paired with the sleeping position information included in the user information for each of the multiple users.

[0110] For example, if the user information corresponding to user A includes the seating style information "seating style a" and the sleeping position information "supine position," the seating style information in Table 3 is used to obtain the first coefficient Ka paired with "seating style a," and the sleeping position information in Table 4 is used to obtain the second coefficient Ks paired with "supine position."

[0111] Then, the first thermal resistance acquisition unit 122a performs a first multiplication by multiplying the bedding thermal resistance value B by a first coefficient K1 and a second multiplication by multiplying the bedding thermal resistance value M by a second coefficient K2 for each of the multiple users, and acquires a first total thermal resistance value I1 by adding the clothing thermal resistance value R, the result of the first multiplication (K1 x B), and the result of the second multiplication (K2 x M).

[0112] For example, in the above example of user A, the clothing thermal resistance value R1, the result of the first multiplication (Ka × B1), and the result of the second multiplication (Ks × M2) are added together to obtain the first total thermal resistance value I1 = R1 + (Ka × B1) + (Ks × M2).

[0113] In this way, the first thermal resistance acquisition unit 122a can acquire the first total thermal resistance value when the bedding 202 includes a duvet 202a and / or a mattress 202b by calculation based on type information, aspect information, thermal resistance information, and coefficient information.

[0114] (2-1-4h) Modification of the method for calculating the first total thermal resistance value In calculating the first total thermal resistance value, the distinction between the comforter 202a and the mattress 202b and the multiplication of the first and second coefficients may be omitted. In this case, the first total thermal resistance value is calculated using the following formula (Formula 2): I1=R+B+M (Formula 2)

[0115] Specifically, the first thermal resistance acquisition unit 122a uses clothing thermal resistance information to acquire, for each of a plurality of users, a clothing thermal resistance value paired with clothing type information included in the user information.

[0116] Furthermore, the first thermal resistance acquisition unit 122a uses the bedding thermal resistance information to acquire a bedding thermal resistance value paired with the bedding type information included in the user information.

[0117] Then, the first thermal resistance acquisition unit 122a acquires a first total thermal resistance value by adding up the clothing thermal resistance value and the bedding thermal resistance value for each of the multiple users.

[0118] This allows the first overall thermal resistance value to be obtained by calculation when the thermal resistance member 200 includes the clothing 201 and / or the bedding 202.

[0119] (2-1-5) Calculation of the second total thermal resistance value (2-1-5a) Metabolic-related information The user information further includes metabolic-related information. Metabolic-related information is information related to metabolic heat production. The metabolic-related information is, for example, information such as the height, weight, and gender of the user, and the metabolic heat production of the user is calculated based on this information. However, the metabolic-related information may also be metabolic heat production calculated in advance based on information such as the height, weight, and gender of the user.

[0120] (2-1-5b) Function for Evaluation Process In the evaluation process, an evaluation value is calculated using a function that uses at least metabolic heat production, thermal resistance, temperature, and humidity as parameters. Such a function is, for example, a function based on PMV, and is expressed as in the following equation (Equation 3), where PMV is the evaluation value, M is the metabolic heat production, I is the thermal resistance, T is the temperature, and H is the humidity. PMV=f(M, I, T, H) (Equation 3)

[0121] (2-1-5c) Method for calculating second total thermal resistance value The second thermal resistance acquisition unit 122b calculates the metabolic heat production M for each of multiple users based on metabolic-related information, and obtains the thermal resistance value I by substituting the calculated metabolic heat production M, the target temperature T set by the control unit 121, and the predetermined humidity H into a function (Equation 3), and sets the obtained thermal resistance value I as the second total thermal resistance value I2.

[0122] In this way, the second total thermal resistance value can be obtained by substituting the metabolic heat production calculated from the metabolic-related information, the set target temperature, and the predetermined humidity into a function for evaluation processing (e.g., a PMV function, etc.) to calculate the thermal resistance value.

[0123] (2-2) Receiving Multiple Modes and Selected Modes The air conditioning control proposal system 100 of this embodiment further includes a receiving unit 11.

[0124] The reception unit 11 can receive a selection mode based on an operation by one of a plurality of users (hereinafter, may be simply referred to as "one user").

[0125] (2-2-1) Selection Mode The selection mode is one mode selected from a plurality of modes.

[0126] (2-2-2) Multiple Modes In this embodiment, the multiple modes are five modes: manual mode, priority mode, standard mode, energy saving mode, and air conditioning stop mode.

[0127] (2-2-3) Modification of Multiple Modes However, the control unit 121 may perform control processing in a selected mode selected from multiple modes including two or more of the above five modes. The multiple modes including two or more of the above five modes may be, for example, four modes excluding the air conditioning stop mode, three modes excluding the energy saving mode and the air conditioning stop mode, or two modes excluding the manual mode, the energy saving mode, and the air conditioning stop mode, and any combination of multiple modes is acceptable.

[0128] (2-2-4) Control Processing According to Selected Mode The control unit 121 in this embodiment performs control processing according to the selected mode selected from the above five modes.

[0129] Furthermore, when the manual mode is selected, the reception unit 11 can receive a set temperature based on an operation by a single user. The operation by the single user is, for example, an operation on the terminal 20 (for example, a mobile terminal of the single user).

[0130] (2-2-5) Multiple Types of Operation by Air Conditioning Unit: Cooling Operation and Heating Operation The air conditioning unit 101 in this embodiment selectively performs one of multiple types of operation.

[0131] The multiple types of operation include cooling operation and heating operation. In cooling operation, air conditioning is performed to lower the temperature, and in heating operation, air conditioning is performed to raise the temperature. Note that in cooling operation, a dehumidifying operation may also be performed, and in heating operation, a humidifying operation may also be performed.

[0132] (2-3) Manual Mode When the manual mode is selected, the control unit 121 performs a first setting process.

[0133] (2-3-1) First Setting Process The first setting process is a process of setting the set temperature received by the receiving unit 11 as the target temperature.

[0134] (2-3-2) Advantages of Manual Mode In this way, by setting the target temperature to a temperature set by one user (manual mode), it is possible to ensure the comfort of at least one user out of multiple users sleeping in one room.

[0135] Furthermore, even if the target temperature does not provide comfort to one or more users other than the one user, the comfort of each of the multiple users sleeping in a room can be provided by proposing to each of the multiple users (preferably, each of the one or more users other than the one user) a thermal resistance member 200 whose evaluation value regarding thermal sensation of each of the multiple users (preferably, each of the one or more users other than the one user) satisfies the comfort conditions.

[0136] (2-4) Priority Mode When the priority mode is selected, the control unit 121 performs a second setting process.

[0137] (2-4-1) Second setting process The second setting process is a process of calculating the temperature T by substituting into the function (Equation 3) an evaluation value that satisfies the comfort conditions (e.g., PMV = 0), the metabolic heat production amount M included in the user information corresponding to one of multiple users, the first total thermal resistance value I1 acquired by the first thermal resistance acquisition unit 122a for that one user, and the predetermined humidity H, and setting the calculated temperature as the target temperature.

[0138] (2-4-2) Advantages of Priority Mode In this way, by setting the target temperature to a calculated temperature based on the user information of a single user (priority mode), it is possible to ensure the comfort of at least one user out of multiple users sleeping in a single room.

[0139] Furthermore, even if comfort for one or more users other than the one user cannot be ensured at the target temperature, the comfort of each of the multiple users sleeping in a single room can be ensured by proposing to each of the multiple users (preferably, each of the one or more users other than the one user) a thermal resistance member 200 whose evaluation value regarding thermal sensation for each of the multiple users (preferably, each of the one or more users other than the one user) satisfies the comfort conditions.

[0140] (2-4-3) Suggested Targets in Manual Mode and Priority Mode When either the manual mode or the priority mode is selected, the suggestion acquisition unit 122c acquires suggestion information for each of one or more users, excluding one user, among the multiple users.

[0141] In this way, by excluding the user who has already been made comfortable by setting the target temperature from the targets of suggestions regarding the heat resistance member 200, it is possible to improve the efficiency of suggestions.

[0142] (2-5) Standard Mode When the standard mode is selected, the control unit 121 performs a third setting process.

[0143] (2-5-1) Third setting process The third setting process is a process of calculating the temperature T for each of a plurality of users by substituting into a function (Equation 3) an evaluation value that satisfies the comfort conditions (e.g., PMV = 0), the metabolic heat production amount M included in the user information corresponding to each of the plurality of users, the first total thermal resistance value I1 acquired by the first thermal resistance acquisition unit 122a for each of the plurality of users, and a predetermined humidity H, and setting a representative value of the plurality of calculated temperatures corresponding to the plurality of users as the target temperature.

[0144] (2-5-2) Representative Value The representative value is a value that represents multiple calculated temperatures, for example, the average value of multiple calculated temperatures. However, if the number of users is three or more, the representative value may be the median value of the three or more calculated temperatures.

[0145] (2-5-3) Advantages of Standard Mode In this way, by setting the representative value of multiple calculated temperatures corresponding to multiple users as the target temperature (standard mode), it is possible to bring all users as close as possible to a state in which comfort conditions are satisfied.

[0146] (2-6) Energy Saving Mode When the energy saving mode is selected, the control unit 121 performs a fourth setting process.

[0147] (2-6-1) Fourth Setting Process The fourth setting process is a process of calculating the temperature T for each of a plurality of users by substituting into a function (Equation 3) an evaluation value that satisfies the comfort conditions (e.g., PMV = 0), the metabolic heat production amount M included in the user information corresponding to each of the plurality of users, the first overall thermal resistance value I1 acquired by the first thermal resistance acquisition unit 122a for each of the plurality of users, and a predetermined humidity H, and setting the highest calculated temperature among the plurality of calculated temperatures corresponding to the plurality of users during cooling operation and the lowest calculated temperature during heating operation as the target temperature.

[0148] (2-6-2) Advantages of Energy-Saving Mode In this way, in the energy-saving mode, by setting the calculated air temperature according to the cooling / heating operation as the target temperature, it is possible to achieve energy savings while improving the comfort of all users.

[0149] (2-7) Air Conditioning Stop Mode When the air conditioning stop mode is selected, the control unit 121 performs the fifth setting process and the stop setting process.

[0150] (2-7-1) Fifth Setting Process The fifth setting process is a process of obtaining an estimated temperature that estimates the temperature T during the sleeping period when the air conditioning process is stopped, and setting the estimated temperature as the target temperature.

[0151] In the fifth setting process, an estimated humidity is also preferably obtained. For example, the estimated temperature and humidity for the next sleeping period are obtained from the detection history (e.g., temperature and humidity for past sleeping periods) of the environmental sensor 21 (temperature and humidity sensor). The estimated temperature and humidity may be obtained based on information such as a weather forecast provided by a server (not shown) of a weather forecasting company or the like.

[0152] (2-7-2) Stop Setting Process The stop setting process is a process for setting the air conditioning unit 101 to stop air conditioning during the sleeping period.

[0153] (2-7-3) Advantages of air conditioning stop mode In this way, by proposing to each of multiple users a thermal resistance member 200 whose evaluation value for each of the multiple users' thermal sensation satisfies the comfort conditions when air conditioning processing is not performed during the sleeping period and the air temperature becomes the estimated temperature, it is possible to ensure the comfort of each of multiple users sleeping in a single room even when air conditioning processing is stopped.

[0154] (2-8) Acquisition and Output of Multiple Proposal Information The proposal acquisition unit 122c acquires the proposal information for each of the multiple users, and outputs the multiple pieces of proposal information corresponding to the multiple users via the output unit 13.

[0155] In this way, even if the set target temperature does not satisfy the comfort conditions of any of the users, the comfort of all users can be improved by providing suggested information for each user.

[0156] (2-9) Mode selection from multiple modes (Mode selection is possible among multiple modes including two or more of the following: manual mode, priority mode, average mode, and energy saving mode)

[0157] (2-10) Advantages of Mode Selection In this way, by making it possible to select from multiple modes, it is possible to ensure the comfort of each of multiple users sleeping in the same room by setting a target temperature according to the situation.

[0158] (2-11) Changing the combination in response to a user's negative judgment on a proposal The reception unit 11 can receive at least a negative judgment result from each of one or more users on each of one or more pieces of proposal information output via the output unit 13.

[0159] The receiving unit 11 may be capable of receiving not only a negative determination result but also a positive determination result. Furthermore, it is preferable that a determination result such as a negative determination result is received before the start of the sleeping period, but it may also be received after the start of the sleeping period.

[0160] The proposal acquisition unit 122c reacquires proposal information in which the above combination has been changed while the matching condition is still satisfied (for example, with PMV = 0) for one or more users among the one or more users for whom the reception unit 11 has received a negative judgment result, and outputs the proposal information via the output unit 13.

[0161] Note that the reacquisition of the proposed information with the changed combination may be repeated a predetermined number of times. That is, the proposal acquisition unit 122c may repeat a predetermined number of steps: outputting the proposed information, receiving the determination result, and reacquiring the proposed information with the changed combination while the matching condition is still satisfied based on the determination result.

[0162] In this way, by reacquiring suggested information in response to a user's negative judgment on the suggested information, it is possible to meet the needs of each user and improve the comfort of each user.

[0163] (2-12) Correction of Target Temperature or Suggestion Information According to User's Suggestion Implementation Results After the start of the sleeping period, the reception unit 11 can receive one or more pieces of thermal sensation information based on the operation of one or more users.

[0164] (2-12-1) Thermal Sensation Information The thermal sensation information is information relating to the thermal sensation of the user. In this embodiment, the thermal sensation information is information indicating the thermal sensation during the sleeping period, that is, the thermal sensation felt by the user wearing the proposed combination of clothing 201 and bedding 202 in a room where the air temperature is adjusted to the target temperature.

[0165] (2-12-2) Control Result Evaluation Screen Thermal sensation information is received, for example, through a control result evaluation screen such as that shown in Fig. 14. This control result evaluation screen includes a question, "How hot / cold was it last night?", three answers to the question, "It was comfortable," "It was hot," and "It was cold," and three check boxes corresponding to the three answers.

[0166] Image data of the control result evaluation screen is transmitted to the plurality of terminals 20 via the output unit 13, and a control result evaluation screen such as that shown in Fig. 14 is displayed on the display of each of the plurality of terminals 20. When a user performs an operation to check a checkbox on the control result evaluation screen displayed on the display of the terminal 20, thermal sensation information based on that operation is transmitted from the communication module of the terminal 20 to the control device 1, and received by the communication module of the control device 1, and the receiving unit 11 receives the received thermal sensation information.

[0167] In this embodiment, each of the one or more pieces of thermal sensation information received by the reception unit 11 is information input (usually afterwards) by each of one or more users, but it may also be information obtained automatically (usually in real time) based on the output of a sleep sensor 22 worn by each of one or more users.

[0168] Note that "after the start of the sleeping period" usually refers to the end of the sleeping period, but may also refer to the time during the sleeping period. In other words, the one or more users who are the target of the proposal basically perform an operation to input thermal sensation information after the end of the sleeping period (e.g., after waking up), but the operation to input thermal sensation information may also be performed during the sleeping period (e.g., before falling asleep).

[0169] (2-13) Correction Unit The air conditioning control proposal system 100 in this embodiment further includes a correction unit 123.

[0170] The correction unit 123 corrects at least one of the target temperature and the suggested information based on one or more pieces of thermal sensation information received by the reception unit 11 .

[0171] In detail, the correction unit 123 may acquire one or more evaluation values ​​corresponding to one or more users based on one or more pieces of thermal sensation information, and based on the acquired one or more evaluation values, perform at least one of correcting the target temperature via the control unit 121 and correcting the proposed information via the proposing unit 122. The correction of the proposed information is, for example, acquiring new proposed information in which the combination is changed while the matching condition is still satisfied.

[0172] In this way, by modifying the target temperature and / or the proposed information depending on the results of the user's implementation of the proposal, it is possible to reflect the modified results in the next proposal, thereby making each user even more comfortable.

[0173] (2-14) Correction of target temperature or proposed information according to the degree of agreement between thermal sensation information When the reception unit 11 receives two or more pieces of thermal sensation information, the correction unit 123 obtains the degree of agreement between the two or more pieces of thermal sensation information, and if the degree of agreement is equal to or greater than a threshold, causes the control unit 121 to correct the target temperature, and if the degree of agreement is less than the threshold, causes the proposal unit 122 to correct the proposed information.

[0174] (2-14-1) Degree of Matching The degree of matching is information indicating the degree of matching, for example, whether or not two pieces of thermal sensation information corresponding to two users match each other (e.g., "1" if they match, "0" if they do not match).

[0175] Alternatively, the degree of agreement may be, for example, the proportion of three or more pieces of thermal sensation information that are in agreement with each other (or whose difference is equal to or less than a threshold value).

[0176] In this way, by correcting the target temperature when the degree of agreement between the thermal sensation information is high, and correcting the suggested information when the degree of agreement is low, it is possible to efficiently improve the comfort of each user.

[0177] (2-14-2) Correction of Target Temperature Correction of the target temperature is, for example, adding a temperature correction value (ΔT) to the target temperature. The added temperature correction value ΔT may be a negative value.

[0178] The modifying unit 123 sets the temperature correction value ΔT to 0 when the degree of coincidence is equal to or greater than the threshold and the thermal sensation information for which the degree of coincidence is equal to or greater than the threshold indicates comfort.

[0179] Furthermore, when the degree of coincidence is equal to or greater than the threshold and the thermal sensation information for which the degree of coincidence is equal to or greater than the threshold indicates hotness, the modifying unit 123 sets the temperature correction value ΔT to a negative value.

[0180] Furthermore, if the degree of coincidence is equal to or greater than a threshold and the thermal sensation information for which the degree of coincidence is equal to or greater than the threshold indicates cold, the modifying unit 123 sets the temperature correction value ΔT to a positive value.

[0181] On the other hand, if the degree of match is less than the threshold, the correction unit 123 changes the evaluation value for users whose thermal sensation information indicates that they are hot to a value indicating that they are cold (for example, a negative value in the case of an evaluation value based on PMV), and causes the proposed information to be re-acquired with the changed combination while the match condition is met, and changes the evaluation value for users whose thermal sensation information indicates that they are cold to a value indicating that they are hot (for example, a positive value in the case of an evaluation value based on PMV), and causes the proposed information to be re-acquired.

[0182] This makes it possible to efficiently and accurately improve the comfort of each user.

[0183] (2-15) Period Determination Process The control unit 121 further executes period determination process.

[0184] The period determination process is a process for determining an air conditioning period. In this embodiment, the period determination process acquires the bedtime and wake-up time for each of multiple users, determines the start time of the sleeping period based on the multiple bedtimes corresponding to the multiple users, and determines the end time of the sleeping period based on the multiple wake-up times corresponding to the multiple users.

[0185] The start time of the sleep period is, for example, the first bedtime among the multiple bedtimes, but may also be the bedtime of one user among the multiple bedtimes. The end time of the sleep period is, for example, the last wake-up time among the multiple wake-up times, but may also be the wake-up time of one user among the multiple wake-up times.

[0186] (2-15-1) Bedtime The bedtime acquired by the period determination process is, for example, the time (detected value) when falling asleep is detected by the sleep sensor 22, but it may also be the time (input value) based on a user operation. Note that, for example, falling asleep means getting into bed if the sleep sensor 22 is a pressure sensor, but may also mean falling asleep if the sleep sensor 22 is a heart rate sensor.

[0187] (2-15-2) Wake-up time The wake-up time obtained by the period determination process is, for example, the time (calculated value) obtained by adding the bedtime (detected value) detected by the sleep sensor 22 to the sleep duration input in advance (input value: sleep duration included in the user information), but it may also be the time (detected value) detected by the sleep sensor 22.

[0188] (2-15-3) Start and End of Air Conditioning Process in Air Conditioning Period The air conditioning unit 101 starts the air conditioning process at the start time of the sleeping period and ends the air conditioning process at the end time of the sleeping period.

[0189] (2-15-4) Determining the sleeping period based on the bedtime and wake-up time In this way, by determining the sleeping period based on each user's bedtime and wake-up time, air conditioning processing can be performed throughout the sleeping period, including each user's sleeping period.

[0190] (2-16) Variant of time detection: Detection of bedtime and wake-up time using sleep sensor The control unit 121 obtains the bedtime and wake-up time for each of multiple users based on the output of the sleep sensor 22 corresponding to each of the multiple users.

[0191] For example, if the sleep sensor 22 is a pressure sensor, the control unit 121 may determine the time when the output signal from the pressure sensor rises as the bedtime and the time when the output signal from the pressure sensor falls as the wake-up time. Alternatively, if the sleep sensor 22 is a heart rate sensor, the control unit 121 may determine the time when the heart rate over a certain period based on the output signal from the heart rate sensor falls below a threshold as the sleep onset time and the time when the heart rate rises above the threshold as the wake-up time.

[0192] In this way, by detecting the bedtime and wake-up time of each user with the sleep sensor 22, the sleeping period can be automatically determined.

[0193] (2-17) Calculation of Wake-up Time Based on Bedtime and Sleeping Duration As described above, the receiving unit 11 can receive the sleeping duration or the wake-up time for each of a plurality of users.

[0194] The control unit 121 acquires the bedtime for each of the multiple users based on the output of the sleep sensor 22 corresponding to each of the multiple users. Then, for each user whose sleeping time has been accepted by the accepting unit 11, the control unit 121 calculates the wake-up time based on the bedtime and sleeping time.

[0195] In this way, the sleep time or wake-up time is accepted by each user through prior operation, and only the bedtime is detected by each user's sleep sensor 22. For users whose sleep time has been accepted, the wake-up time is obtained based on the bedtime and sleep time. This allows the sleep period to be determined semi-automatically while ensuring the freedom of each user in setting their wake-up time.

[0196] (2-18) Receiving Thermal Sensation Information Based on Sleep Information As described above, a plurality of sleep sensors 22 are arranged in the room in association with a plurality of users.

[0197] The control unit 121 further acquires sleep information for each of the users during the sleep period based on the output of the sleep sensor 22 corresponding to each of the users. The sleep information is information relating to at least one of the length and depth of sleep. Specifically, the sleep information may include, for example, the sleeping time and the frequency of turning over in sleep.

[0198] The control unit 121 then causes the receiving unit 11 to receive thermal sensation information for a user corresponding to sleep information that satisfies the deficiency condition, among the plurality of pieces of sleep information corresponding to the plurality of users.

[0199] The sleep deficiency condition is a condition for determining whether or not sleep is insufficient. Examples of the sleep deficiency condition include "time is below a threshold," "the frequency of turning over in sleep is above a threshold," and "time is below a threshold and the frequency of turning over in sleep is above a threshold."

[0200] In this way, by receiving thermal sensation information only from users who are determined to be sleep-deprived based on the output of the sleep sensor 22, it is possible to efficiently make each user feel even more comfortable.

[0201] (2-19) Evaluation Process by Control Unit The control process may further include evaluation process.

[0202] The control unit 121 may calculate an evaluation value for each of the multiple users by, for example, substituting into a function (Equation 3) the metabolic heat production amount contained in the user information corresponding to each of the multiple users, the first total thermal resistance value I1 acquired by the first thermal resistance acquisition unit 122a for each of the multiple users, and the temperature T and humidity H detected by the environmental sensor 21.

[0203] The calculated evaluation value may be output (e.g., displayed on a display) via the output unit 13. Alternatively, the target temperature may be controlled during periods other than the sleeping period based on the calculated evaluation value.

[0204] This allows various processes to be performed using the evaluation value, for example, it is possible to set a target temperature based on the evaluation value during periods other than the sleeping period.

[0205] (3) Operation Next, the operation of air conditioning control proposal system 100 will be described using Figures 2 to 10. Note that the processing according to the flowcharts in Figures 2 to 10 is started when air conditioning control proposal system 100 is started, and is ended when operation is stopped.

[0206] (3-1) Overall Operation When the process starts, the processing unit 12 constituting the control device 1 performs an initial process (step S1). The initial process includes, for example, accepting a selected mode and registering user information.

[0207] Note that the values ​​of various parameters, such as the selected mode, target temperature, and sleep period, immediately before the previous operation was stopped are stored in memory, and these stored values ​​become the initial values ​​of the various parameters at the current startup. When new values ​​of the various parameters are accepted during the initialization process, the stored values ​​of the various parameters are updated to the new values. For example, when a new selected mode is accepted during the initialization process, the stored value of the selected mode is updated to the newly accepted value.

[0208] After the initial process, the control unit 121 constituting the processing unit 12 performs a setting process (step S2). The setting process will be described with reference to FIGS.

[0209] When the setting process is completed, the proposing unit 122 makes a proposal (step S3). The proposal will be described with reference to FIG.

[0210] After the suggestion, the processing unit 12 determines whether the current time has reached the start time of the sleeping period (step S4). If it is determined that the start time has not yet been reached, the processing returns to step S4.

[0211] If it is determined in step S4 that the start time has been reached, the processing unit 12 determines (step S5) whether or not an air conditioning stop setting has been made for the air conditioning unit 101 that constitutes the air conditioning equipment 10. If it is determined here that an air conditioning stop setting has been made, the processing proceeds to step S7 (described below).

[0212] If it is determined in step S5 that the air conditioning stop setting has not been made, the processing unit 12 causes the air conditioning unit 101 to perform air conditioning processing (step S6). In the air conditioning processing, air conditioning operation is performed so that the air temperature detected by the environment sensor 21 approaches the set target temperature.

[0213] Next, the processing unit 12 determines whether the current time has reached the end time of the sleeping period (step S7). If it is determined that the end time has not yet been reached, the processing returns to step S5.

[0214] If it is determined in step S7 that the end time has been reached, the correction unit 123 makes a correction (step S8). The correction will be described with reference to Fig. 10. After the correction, the process returns to step S4.

[0215] (3-2) Setting Process The setting process in step S2 is executed, for example, according to the flowchart in FIG.

[0216] First, the control unit 121 determines whether the current mode is the air conditioning stop mode (step S201). If it is determined that the current mode is the air conditioning stop mode, the process proceeds to step S210 (described later).

[0217] If it is determined in step S201 that the current mode is not the air conditioning stop mode, the control unit 121 determines whether the current mode is the manual mode (step S202). If it is determined that the current mode is not the manual mode, the process proceeds to step S204.

[0218] If it is determined in step S202 that the mode is the manual mode, the control unit 121 performs a first setting process (step S203). The first setting process will be described with reference to Fig. 4. After that, the process returns to the upper flowchart.

[0219] If it is determined in step S202 that the current mode is not the manual mode, the control unit 121 determines whether the current mode is the priority mode (step S204). If it is determined that the current mode is not the priority mode, the process proceeds to step S206 (described below).

[0220] If the priority mode is determined in step S204, the control unit 121 performs a second setting process (step S205). The second setting process will be described with reference to Fig. 5. After that, the process returns to the upper flowchart.

[0221] If it is determined in step S204 that the current mode is not the priority mode, the control unit 121 determines whether the current mode is the standard mode (step S206). If it is determined that the current mode is not the standard mode, the process proceeds to step S208 (described below).

[0222] If it is determined in step S206 that the standard mode is selected, the control unit 121 performs a third setting process (step S207). The third setting process will be described later with reference to Fig. 6. After that, the process returns to the upper flowchart.

[0223] If it is determined in step S206 that the current mode is not the standard mode, the control unit 121 determines whether the current mode is the energy saving mode (step S208). If it is determined that the current mode is not the energy saving mode, the process returns to the upper flowchart.

[0224] If it is determined in step S208 that the power saving mode is selected, the control unit 121 performs a fourth setting process (step S209). The fourth setting process will be described with reference to Fig. 7. After that, the process returns to the upper flowchart.

[0225] If it is determined in step S201 that the air conditioning stop mode is selected, the control unit 121 performs a fifth setting process (step S210). The fifth setting process will be described with reference to FIG.

[0226] Next, the control unit 121 sets the air conditioning unit 101 to stop air conditioning (step S211). After that, the process returns to the upper flowchart.

[0227] (3-2-1) First Setting Process The first setting process in step S203 is executed, for example, according to the flowchart of FIG.

[0228] The control unit 121 receives the set temperature via the reception unit 11 (step S203a).

[0229] Next, the control unit 121 sets the set temperature received in step S203a as the target temperature (T) (step S203b), after which the process returns to the upper flowchart.

[0230] (3-2-2) Second Setting Process The second setting process in step S205 is executed, for example, according to the flowchart of FIG.

[0231] The control unit 121 obtains one calculated temperature corresponding to one user using a function (for example, Equation 3: the same applies below) (step S205a).

[0232] Next, the control unit 121 sets the calculated temperature acquired in step S205a as the target temperature (T) (step S205b), after which the process returns to the upper-level flowchart.

[0233] (3-2-3) Third Setting Process The third setting process in step S207 is executed, for example, according to the flowchart of FIG.

[0234] The control unit 121 uses a function to obtain a plurality of calculated temperatures corresponding to a plurality of users (step S207a).

[0235] Next, the control unit 121 obtains a representative value (for example, an average value) of the calculated temperatures obtained in step S207a (step S207b).

[0236] Next, the control unit 121 sets the representative value acquired in step S207b as the target temperature (T) (step S207c), and then the process returns to the upper-level flowchart.

[0237] (3-2-4) Fourth Setting Process The fourth setting process in step S209 is executed, for example, according to the flowchart of FIG.

[0238] The control unit 121 uses a function to obtain a plurality of calculated temperatures corresponding to a plurality of users (step S209a).

[0239] Next, the control unit 121 determines whether the current air conditioning operation of the air conditioner 101 is cooling operation (step S209b). If it is determined that the current air conditioning operation is not cooling operation (i.e., heating operation), the process proceeds to step S209d (described later).

[0240] If it is determined in step S209b that the cooling operation is in progress, the control unit 121 sets the highest calculated temperature among the plurality of calculated temperatures acquired in step S209 as the target temperature (T) (step S209c). After that, the process returns to the upper-level flowchart.

[0241] The control unit 121 then returns the processing to the upper flowchart.

[0242] If it is determined in step S209a that the operation is not cooling, the control unit 121 sets the lowest calculated temperature among the plurality of calculated temperatures acquired in step S209 as the target temperature (T) (step S209d). After that, the process returns to the upper-level flowchart.

[0243] (3-2-5) Fifth Setting Process The fifth setting process in step S210 is executed, for example, according to the flowchart of FIG.

[0244] The control unit 121 acquires an estimated temperature during the sleeping period based on the temperature and humidity detection history by the environment sensor 21 (step S210a).

[0245] Next, the control unit 121 sets the estimated air temperature acquired in step S210a as the target temperature (T) (step S210b), after which the process returns to the upper-level flowchart.

[0246] (3-3) Proposal The proposal in step S3 is executed, for example, according to the flowchart of FIG.

[0247] The first thermal resistance acquisition unit 122a, which constitutes the proposal unit 122, acquires a first total thermal resistance value (I1) calculated for each of multiple users based on a combination of the type and usage mode of the thermal resistance member 200 (step S301).

[0248] Next, the second thermal resistance acquisition unit 122b acquires a second total thermal resistance value (I2) for each of the multiple users, which is the thermal resistance value such that the evaluation value at the target temperature (T) satisfies the comfort condition (e.g., PMV = 0) (step S302).

[0249] Next, the proposal acquisition unit 122c acquires proposal information regarding a new combination that satisfies the matching condition for each of one or more users whose first total thermal resistance value (I1) acquired in step S301 and the second total thermal resistance value (I2) acquired in step S302 do not satisfy the matching condition, and outputs the information via the output unit 13 (step S303).

[0250] Next, the correction unit 123 reacquires the proposal information obtained by correcting the combination while keeping the matching condition satisfied for each of the one or more users who have received a negative determination result for the proposal information output in step S303, and outputs the proposal information via the output unit 13 (step S304). After that, the process returns to the upper-level flowchart.

[0251] (3-4) Correction The correction in step S8 is carried out, for example, according to the flowchart of FIG.

[0252] The correcting unit 123 determines whether the receiving unit 11 has received thermal sensation information (step S801). If it is determined that the thermal sensation information has not been received, the process returns to the upper flowchart.

[0253] If it is determined in step S801 that thermal sensation information has been received, the correcting unit 123 determines whether the number of pieces of thermal sensation information received is two or more (step S802). If it is determined that the number of pieces of thermal sensation information received is not two or more (i.e., one), the process proceeds to step S806 (described below).

[0254] If it is determined in step S802 that the number of pieces of thermal sensation information is two or more, the corrector 123 determines whether the degree of agreement between the two or more pieces of thermal sensation information is equal to or greater than a threshold (step S804). If it is determined that the degree of agreement is not equal to or greater than the threshold (i.e., less than the threshold), the process proceeds to step S6 (described below).

[0255] If it is determined in step S804 that the degree of coincidence is equal to or greater than the threshold value, the modifying unit 123 modifies the target temperature (step S805), after which the process returns to the upper-level flowchart.

[0256] If it is determined in step S802 that the number of pieces of thermal sensation information is not two or more, or if it is determined in step S804 that the degree of coincidence is not equal to or greater than the threshold, the suggestion acquisition unit 122c corrects the suggestion information (step S806). After that, the process returns to the upper-level flowchart.

[0257] (4) Method and Program Note that functions similar to those of the air conditioning control proposal system 100 according to this embodiment may be embodied as an air conditioning control proposal method, a (computer) program, or a non-transitory recording medium on which a program is recorded.

[0258] The air conditioning control proposal method is a method that includes at least step S2 (setting step) and step S3 (proposal step) from the steps described above (see FIGS. 2 to 10).

[0259] The program is a program for causing one or more processors to execute the air-conditioning control proposal method. The one or more processors may be a processor of the control device 1 alone, or may include a processor of the air conditioning equipment 10. The program may further include multiple processors corresponding to multiple terminals 20.

[0260] (5) Summary The air conditioning control proposal system (100) according to the first aspect of the present disclosure includes a control unit (121) and a proposal unit (122). The control unit (121) performs a control process on the air conditioning unit (101) that performs an air conditioning process. The air conditioning process is a process for adjusting one or more physical quantities including at least the temperature of the air in the room. The control process includes a setting process. The setting process is a process for setting a target temperature for the air conditioning process during a sleeping period. The sleeping period is a period during which multiple users sleep in the room. The proposal unit (122) acquires proposal information for proposing to each of the multiple users a thermal resistance member (200) that covers the bodies of each of the multiple users during the sleeping period and prevents heat dissipation from the bodies to the room, such that the evaluation value related to the thermal sensation of each of the multiple users at the target temperature satisfies a comfort condition. Then, the proposal unit (122) outputs, via the output unit (13), one or more pieces of proposal information corresponding to one or more users out of the plurality of pieces of proposal information corresponding to the plurality of users.

[0261] According to this aspect, by proposing to each of the multiple users a thermal resistance member (200) whose evaluation value regarding the thermal sensation of each of the multiple users satisfies the comfort conditions when air conditioning processing is performed during the sleeping period and the air temperature reaches the target temperature, it is possible to make each of the multiple users sleeping in one room more comfortable.

[0262] In the air conditioning control proposal system (100) according to the second aspect, in the first aspect, an environmental sensor (21) is disposed in the room. The environmental sensor (21) is capable of detecting at least the air temperature. The proposal unit (122) includes a first thermal resistance acquisition unit (122a), a second thermal resistance acquisition unit (122b), and a proposal acquisition unit (122c). The first thermal resistance acquisition unit (122a) acquires a first total thermal resistance value for each of the plurality of users. The first total thermal resistance value is a thermal resistance value calculated based on a combination of the type and usage mode of the thermal resistance member (200). The second thermal resistance acquisition unit (122b) acquires a second total thermal resistance value for each of the plurality of users. The second total thermal resistance value is the thermal resistance value such that the evaluation value satisfies the comfort condition when the air temperature is adjusted to the target temperature in an evaluation process that evaluates a thermal sensation based at least on metabolic heat production, the thermal resistance value of the thermal resistance member (200), and the one or more physical quantities including the air temperature, and acquires an evaluation value. The proposal acquisition unit (122c) acquires the proposal information regarding a new combination that satisfies the matching condition for one or more users among the plurality of users whose first total thermal resistance value does not satisfy the matching condition with the second total thermal resistance value, and outputs the one or more pieces of proposal information corresponding to the one or more users via the output unit (13).

[0263] According to this aspect, by comparing the first total thermal resistance value based on the combination of the type and usage mode of the thermal resistance member (200) with the second total thermal resistance value whose evaluation value at the target temperature satisfies the comfort conditions, new combinations are proposed, thereby making it possible to improve the comfort of each user without obtaining an evaluation value.

[0264] In the air-conditioning control proposal system (100) according to the third aspect, in the second aspect, the first thermal resistance acquisition unit (122a) calculates the first overall thermal resistance value for each of the plurality of users using thermal resistance information and coefficient information based on user information including type information on the type of thermal resistance member (200) and mode information on usage mode. The thermal resistance information is a set of pairs of the type information and the thermal resistance value. The coefficient information is a set of pairs of the mode information and a coefficient.

[0265] According to this aspect, the first total thermal resistance value can be obtained by calculation based on the type information, aspect information, thermal resistance information, and coefficient information.

[0266] In an air conditioning control proposal system (100) according to a fourth aspect, in the third aspect, the one or more physical quantities further include humidity. The environmental sensor (21) is further capable of detecting the humidity. The user information further includes metabolism-related information. The metabolism-related information is information related to the metabolic heat production. The evaluation process is a process of calculating the evaluation value using a function having at least the metabolic heat production, the thermal resistance value, the temperature, and the humidity as parameters. A second thermal resistance acquisition unit (122b) calculates the metabolic heat production for each of the multiple users based on the metabolism-related information, and calculates the second total thermal resistance value by substituting the calculated metabolic heat production, the target temperature, and the predetermined humidity into the function.

[0267] According to this aspect, the second total thermal resistance value can be obtained by calculating the thermal resistance value by substituting the metabolic heat production calculated from the metabolic-related information, the set target temperature, and the predetermined humidity into a function for evaluation processing (e.g., a PMV function, etc.).

[0268] In the air conditioning control proposal system (100) according to the fifth aspect, in the fourth aspect, the thermal resistance member (200) includes at least one of clothing (201) and bedding (202). The thermal resistance information includes clothing thermal resistance information and bedding thermal resistance information. The clothing thermal resistance information is a set of pairs of clothing type information and clothing thermal resistance value. The clothing type information is information regarding the type of clothing (201). The clothing thermal resistance information is the thermal resistance value of the clothing (201). The bedding thermal resistance information is a set of pairs of bedding type information and bedding thermal resistance value. The bedding type information is information regarding the type of bedding (202). The bedding thermal resistance value is the thermal resistance value of the bedding (202). The type information included in the user information includes the clothing type information and the bedding type information. The first thermal resistance acquisition unit (122a) acquires, for each of the plurality of users, the clothing thermal resistance value paired with the clothing type information included in the user information using the clothing thermal resistance information. The first thermal resistance acquisition unit (122a) also acquires the bedding thermal resistance value paired with the bedding type information included in the user information using the bedding thermal resistance information, which is the thermal resistance value of bedding (202). The first thermal resistance acquisition unit (122a) then acquires the first total thermal resistance value by adding the clothing thermal resistance value and the bedding thermal resistance value.

[0269] According to this aspect, the first overall thermal resistance value can be obtained by calculation when the thermal resistance member (200) includes clothing (201) and / or bedding (202).

[0270] In the air conditioning control proposal system (100) according to the sixth aspect, in the fifth aspect, the bedding (202) includes at least one of a comforter (202a) and a mattress (202b). The bedding type information includes comforter type information and mattress type information. The comforter type information is information related to the type of comforter (202a). The mattress type information is information related to the type of mattress (202b). The coefficient information includes first coefficient information and second coefficient information. The first coefficient information is a set of pairs of comforter style information and a first coefficient. The comforter style information is information related to the way the comforter (202a) is put on. The second coefficient information is a set of pairs of sleeping position information and a second coefficient. The sleeping position information is information related to the sleeping position relative to the mattress (202b). The bedding type information included in the user information includes the comforter type information and the mattress type information. The mode information included in the user information includes the comforter style information and the sleeping position information. The first thermal resistance acquisition unit (122a) uses the first coefficient information to acquire, for each of the multiple users, the first coefficient paired with the sleeping style information included in the user information. The first thermal resistance acquisition unit (122a) also uses the second coefficient information to acquire, for each of the multiple users, the second coefficient paired with the sleeping posture information included in the user information. The first thermal resistance acquisition unit (122a) then performs a first multiplication for each of the multiple users, multiplying the clothing thermal resistance value by the acquired second coefficient, and a second multiplication for each of the multiple users, multiplying the bedding thermal resistance value by the acquired second coefficient, and then acquiring the first total thermal resistance value by adding the clothing thermal resistance value, the result of the first multiplication, and the result of the second multiplication.

[0271] According to this aspect, the first overall thermal resistance value can be obtained by calculation when the bedding (202) includes a comforter (202a) and / or a mattress (202b).

[0273] According to this aspect, by setting the target temperature to a temperature set by one user (manual mode), it is possible to ensure the comfort of at least one user among multiple users sleeping in a single room. Also, even if the comfort of one or more users other than the one user cannot be ensured at the target temperature, it is possible to ensure the comfort of each of the multiple users sleeping in a single room by proposing to each of the multiple users a thermal resistance member (200) whose evaluation value regarding the thermal sensation of each of the multiple users satisfies the comfort condition.

[0275] According to this aspect, by setting the target temperature to a calculated temperature based on the user information of one user (priority mode), it is possible to ensure the comfort of at least one user among multiple users sleeping in one room. Also, even if the target temperature does not ensure the comfort of one or more users other than the one user, it is possible to ensure the comfort of each of the multiple users sleeping in one room by proposing to each of the multiple users a thermal resistance member (200) whose evaluation value regarding the thermal sensation of each of the multiple users satisfies the comfort condition.

[0276] In the air conditioning control proposal system (100) according to the ninth aspect, in the seventh or eighth aspect, the proposal acquisition unit (122c) acquires the proposal information for each of one or more users among the plurality of users, excluding the one user.
