Description

[Technical field]

[0001] The present invention relates to a humidity control device and a humidity control method. [Background technology]

[0002] Conventionally, air conditioning control devices that control air conditioning equipment generally adjust the air environment by appropriately performing heating or cooling, or humidification or dehumidification depending on whether the temperature and humidity of the air in a room are high or low relative to the set values ​​of the target temperature and humidity (see, for example, Patent Document 1). In specific buildings to which Japan's Building Sanitation Act (law concerning the maintenance of sanitary environments in buildings) applies, the relative humidity in a room is required to be controlled within the range of 40 to 70% RH as one of the indoor environmental standards.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

[0011] (First embodiment) 1 is an overall view showing an example of an air conditioning system 1A according to a first embodiment. The air conditioning system 1A is a system that adjusts the air environment of a room 10 used by a user U.

[0012] The air conditioning system 1A includes, as the indoor environment of the room 10, a humidity control equipment 2 that adjusts the humidity in the room 10 to a target humidity, a sebum amount measuring device 3 that measures the amount of sebum of a user U using the room 10, an entry / exit management device 4 that manages the entry and exit of the user U to the room 10, a user terminal device 5 carried by the user U, a humidity control device 6A that controls the humidity control equipment 2 by setting a target humidity for the humidity control equipment 2 based on the amount of sebum of the user U, and a network 7 that connects each device so that they can communicate with each other.

[0013] The room 10 is an indoor space assumed to be used by one or more users U, and is used, for example, as an office or an open space. Note that the shape and size of the room 10, and the installation locations of the humidity control equipment 2, the sebum amount measuring device 3, and the entrance and exit management device 4 in the room 10 are not limited to the example shown in FIG.

[0014] The humidity control equipment 2 includes an indoor environment sensor 20 that detects the temperature and humidity of the air in the living room 10, an operation panel 21 that accepts setting operations from a user U or an administrator, and a control panel 22 that controls the operation of the humidity control equipment 2 under the control of the humidity control device 6A. The control panel 22 receives the target humidity set by the humidity control device 6A, and adjusts the humidity of the living room 10 by switching the operation mode (dehumidification mode or humidification mode, strong or weak, etc.) based on the target humidity and the detected temperature and humidity of the indoor environment sensor 20. Note that the humidity control equipment 2 is not limited to the above configuration, and may be configured as an air conditioning equipment that adjusts not only the humidity of the living room 10 but also the temperature of the living room 10 to a target temperature, and may be configured as an air conditioner having an indoor unit and an outdoor unit, for example.

[0015] The target humidity is expressed by a relative humidity, for example, on the premise that the temperature of the living room 10 is adjusted to a constant value. The target humidity is set by the humidity control device 6A within the air environment management standard defined by the Building Sanitation Act, that is, within the range of a relative humidity of 40 to 70% RH. In this case, the target humidity may be set as a target relative humidity of the humidity adjustment equipment 2 (e.g., a relative humidity of "60% RH"), or, when a reference relative humidity (e.g., "55% RH") is set on the operation panel 21, it may be set as a correction amount (e.g., "+5% RH") for the reference relative humidity (e.g., "55% RH").

[0016] The sebum amount measuring device 3 is installed, for example, at the entrance of the room 10, and is a device for measuring the amount of sebum on the skin of the user U, such as the face and arms. The sebum amount measuring device 3 includes a sebum amount sensor 30 according to a method for measuring the amount of sebum, and a display unit 31 for displaying various information including the measurement results by the sebum amount sensor 30. The method for measuring the amount of sebum can be any measuring method, such as an optical method or a method using image processing. The sebum amount measuring device 3 may be a stationary type in which the user U brings the face or arm close to the device to measure the amount of sebum, or a handheld type in which the user U brings a measuring probe held by hand close to the face or arm to measure the amount of sebum.

[0017] The entrance / exit management device 4 is installed, for example, at the entrance of the room 10, and manages the entrance and exit of the user U. The entrance / exit management device 4 acquires a user identifier of the user U who enters or leaves the room 10 by any identification method, for example, fingerprint authentication, face authentication, ID card, etc., and acquires the date and time of entry or the date and time of exit. The entrance / exit management device 4 may be configured as an integrated device with the sebum amount measuring device 3.

[0018] The user terminal device 5 is composed of a portable device such as a mobile phone, a smartphone, or a tablet, and various applications can be installed. The user terminal device 5 has, for example, a skin diagnosis application installed therein, and has a sebum amount measurement function that measures skin information including the sebum amount by analyzing an image of the face of the user U captured by an imaging unit such as a camera. The user terminal device 5 transmits the sebum amount of the user U measured by the sebum amount measurement function to the humidity control device 6A. At that time, the user terminal device 5 may transmit the sebum amount in response to a transmission operation by the user U, or may transmit the sebum amount as a response to a transmission request received from the humidity control device 6A.

[0019] The amount of sebum of the user U may be measured by either the sebum amount measuring device 3 or the user terminal device 5. Therefore, for example, if the user U does not have a user terminal device 5 or does not have a user terminal device 5 having a sebum amount measuring function, the amount of sebum may be measured by the sebum amount measuring device 3.

[0020] The humidity control device 6A controls the humidity control operation of the humidity adjustment equipment 2 by setting a target humidity based on the amount of sebum of the user U measured by the sebum amount measuring device 3 or the user terminal device 5. The humidity control device 6A is configured, for example, with a general-purpose or dedicated computer. The humidity control device 6A may be incorporated in the control panel 22 of the humidity adjustment equipment 2.

[0021] The network 7 may employ any communication method, and may be either wired or wireless.

[0022] (Configuration of humidity control device 6A) FIG. 2 is a block diagram showing an example of a humidity control device 6A according to the first embodiment.

[0023] The humidity control device 6A includes a storage unit 60 including a HDD, an SDD, a memory, etc., a control unit 61 including a processor such as a CPU, an MPU, a GPU, etc., and a communication unit 62 which is a communication interface with the network 7. The humidity control device 6A may further include an input unit including a keyboard, a touch panel, etc., and an output unit including a display, a touch panel, a speaker, etc.

[0024] The storage unit 60 stores a humidity control program 600A and user management information 601A.

[0025] The user management information 601A is information for managing users U who use the room 10. In the user management information 601A, for example, the amount of sebum of the user U and a record of the user U entering and leaving the room are registered in association with each other for each user U. Note that the user management information 601A may be stored in an external storage device capable of communicating with the humidity control device 6A instead of being stored in the storage unit 60.

[0026] The control unit 61 functions as a sebum amount acquiring unit 610, an entrance / exit recording unit 611, and a target humidity setting unit 612 by executing the humidity control program 600A.

[0027] The sebum amount acquisition unit 610 acquires the amount of sebum of the user U who uses the room 10. When there are multiple users U who use the room 10, the sebum amount acquisition unit 610 acquires the amount of sebum of each user U. In this embodiment, when the user U enters the room 10, the sebum amount acquisition unit 610 receives the amount of sebum of the user U measured by the sebum amount measuring device 3 or the user terminal device 5 via the network 7, and registers it in the user management information 601A. At that time, the sebum amount acquisition unit 610 cooperates with the entry / exit recording unit 611 to register the amount of sebum of the user U in association with the user identifier.

[0028] The entry / exit recording unit 611 receives the entry record of the user U (user identifier, entry date and time) acquired by the entry / exit management device 4 via the network 7, and registers it in the user management information 601A. Furthermore, when the user U leaves the room 10, the entry / exit recording unit 611 receives the exit record of the user U (user identifier, exit date and time) acquired by the entry / exit management device 4 via the network 7, and registers it in the user management information 601A.

[0029] The target humidity setting section 612 sets a target humidity based on the amount of sebum of the user U acquired by the sebum amount acquiring section 610.

[0030] In this embodiment, the target humidity setting unit 612 acquires the amount of sebum of each user U in the living room 10 and the number of users U in the living room 10 by referring to the user management information 601A, and sets the target humidity based on the information. For example, when there is one user U, the target humidity setting unit 612 sets the target humidity when the sebum amount of the user U is lower than the sebum amount standard value higher than the target humidity when the sebum amount of the user U is higher than the sebum amount standard value. When there are multiple users U, the target humidity setting unit 612 calculates the ratio of users U in the living room 10 whose sebum amount is lower than the sebum amount standard value based on the sebum amount of each user U, and sets the target humidity when the ratio is higher than the ratio standard value higher than the target humidity when the ratio is lower than the ratio standard value.

[0031] The method of setting the target humidity by the target humidity setting unit 612 is not limited to the above example, and may be changed as appropriate. For example, the target humidity setting unit 612 may set the target humidity to be higher in a stepwise or continuous manner as the sebum amount of the user U decreases, or may set the target humidity to be higher in a stepwise or continuous manner as the proportion of users U whose sebum amount is lower than the sebum amount reference value increases.

[0032] Furthermore, the method of setting the target humidity by the target humidity setting unit 612 when there are multiple users U is not limited to the above example. For example, the target humidity setting unit 612 may calculate statistical values ​​such as the minimum, maximum, and average sebum amount based on the sebum amount for each user U, and set the target humidity when the statistical values ​​are lower than the sebum amount standard value higher than the target humidity when the statistical values ​​are higher than the sebum amount standard value.

[0033] (Operation of humidity control device 6A) Next, the operation of the air conditioning system 1A having the above configuration will be described, focusing on the humidity control device 6A.

[0034] Fig. 3 is a flowchart showing an example of the operation of the humidity control device 6A according to the first embodiment. The series of processes (humidity control method) shown in Fig. 3 are executed by the humidity control device 6A, for example, when a new user U enters the living room 10. The series of processes shown in Fig. 3 may be executed at a predetermined time (e.g., 9:00, etc.) or at predetermined time intervals (e.g., every 3 hours, etc.), or when the number of users U exceeds a predetermined threshold or the change in the number of users U exceeds a predetermined threshold. In that case, steps S100 and S101 described later may be omitted.

[0035] First, when a new user U enters the living room 10, the sebum amount measuring device 3 installed at the entrance of the living room 10 measures the amount of sebum of the user U and transmits it to the humidity control device 6A. In addition, the entry and exit management device 4 installed at the entrance of the living room 10 acquires the user identifier and entry date and time of the user U as a record of the entry of the new user U, and transmits it to the humidity control device 6A. Note that if the new user U has a user terminal device 5 with a sebum amount measuring function, the user terminal device 5 may transmit the amount of sebum of the user U measured by the sebum amount measuring function to the humidity control device 6A.

[0036] As a result, in step S100, the sebum amount acquisition unit 610 receives (acquires) the sebum amount of user U from the sebum amount measuring device 3, and the entry / exit recording unit 611 receives (acquires) the user identifier and entry date and time of user U from the entry / exit management device 4.

[0037] Then, in step S101, the sebum amount acquiring section 610 and the entry / exit recording section 611 register the information received in step S100 (user identifier, sebum amount, and entry date / time) in the user management information 601A.

[0038] Next, in steps S110 to S119, the target humidity setting unit 612 refers to the user management information 601A to obtain the amount of sebum of each user U present in the room 10 and the number of users U present in the room 10, and sets the target humidity based on that information.

[0039] Specifically, if the number of users U present in the room 10 is one (S110: No), in step S111, the target humidity setting unit 612 determines whether the amount of sebum of the user U is equal to or lower than the sebum amount reference value (for example, 20 μg / cm 2 ) is determined.

[0040] Then, if the amount of sebum of user U is lower than the sebum amount standard value (step S111: Yes), in step S112, the target humidity of the humidity adjustment equipment 2 is set to a first relative humidity R1 (e.g., 60% RH), and if the amount of sebum of user U is equal to or greater than the sebum amount standard value (step S111: No), in step S113, the target humidity of the humidity adjustment equipment 2 is set to a second relative humidity R2 (e.g., 50% RH) lower than the first relative humidity R1.

[0041] On the other hand, if there are multiple users U in the room 10 (S110: Yes), in step S114, the target humidity setting unit 612 refers to the user management information 601A and determines whether the amount of sebum among the users U in the room 10 is greater than or equal to the sebum amount reference value (for example, 20 μg / cm 2 ) to calculate the percentage of users U that is lower than

[0042] Then, if the proportion of user U is higher than a first proportion reference value (e.g., 30%) (step S115: Yes), in step S116, the target humidity of the humidity adjustment equipment 2 is set to a first relative humidity R1 (e.g., 60% RH), and if the proportion of user U is lower than a second proportion reference value (e.g., 10%) (step S117: Yes), in step S118, the target humidity of the humidity adjustment equipment 2 is set to a second relative humidity R2 (e.g., 50% RH) lower than the first relative humidity R1.

[0043] Furthermore, if the proportion of users U is lower than the first proportion reference value (e.g., 30%) and higher than the second proportion reference value (e.g., 10%) (step S115: No and S117: No), in step S119, the target humidity of the humidity control equipment 2 is set to a third relative humidity R3 (e.g., 55% RH) that is lower than the first relative humidity R1 and higher than the second relative humidity R2.

[0044] Then, in step S120, the target humidity setting unit 612 transmits the target humidity for the living room 10 set in steps S110 to S19 to the humidity adjustment equipment 2. As a result, the control panel 22 of the humidity adjustment equipment 2 receives the target humidity for the living room 10 from the humidity control device 6, and performs a humidity adjustment operation by switching the operation mode (dehumidification mode or humidification mode, strong or weak, etc.) based on the target humidity and the detected temperature and humidity of the indoor environment sensor 20, so that the humidity in the living room 10 becomes the target humidity.

[0045] As described above, the humidity control device 6A according to this embodiment sets the target humidity for the humidity adjustment equipment 2 based on the amount of sebum of the user U who uses the room 10, and therefore provides an appropriate indoor environment suited to the skin condition of the user U. This can improve the user U's satisfaction with the indoor environment.

[0046] Second embodiment FIG. 4 is an overall view showing an example of an air conditioning system 1B according to the second embodiment. In the air conditioning system 1A according to the first embodiment, the humidity control device 6A adjusts the air environment of one living room 10. In contrast, in the air conditioning system 1B according to the second embodiment, the humidity control device 6B adjusts the air environment of each living room 10 based on the location of a user U in each living room 10, for multiple living rooms 10. Note that the basic configuration is the same as in the first embodiment, so the following description will focus on the differences.

[0047] The air conditioning system 1B includes a plurality of humidity control devices 2 that adjust the humidity of each room 10 to a target humidity, a plurality of user terminal devices 5 owned by each of a plurality of users U, a humidity control device 6B that controls the humidity control device 2 by setting the target humidity of each humidity control device 2 based on the sebum amount of the user U, and a network 7 that connects each device to each other so that they can communicate with each other. Note that the air conditioning system 1B may include a sebum amount measuring device 3 and an entrance and exit management device 4 at the entrance of a building having a shared passage to each room 10, for example. In addition, although two rooms 10 are illustrated in FIG. 4, the number of rooms 10 may be three or more, and the arrangement of each room 10 and the installation location of the humidity control device 2 relative to the rooms 10 are not limited to the example in FIG. 4.

[0048] The user terminal device 5 has a sebum amount measuring function similar to that of the first embodiment, and also has a current location identifying function that identifies the current location of the user terminal device 5 by a position detector such as a GPS. The user terminal device 5 transmits the amount of sebum of the user U measured by the sebum amount measuring function and the current location of the user U identified by the current location identifying function to the humidity control device 6B together with the user identifier of the user U. In this case, the user terminal device 5 may transmit the amount of sebum and the current location in response to a transmission operation by the user U, or may transmit the amount of sebum and the current location as a response to a transmission request when a transmission request is received from the humidity control device 6B.

[0049] 5 is a block diagram showing an example of a humidity control device 6B according to the second embodiment. The humidity control device 6B includes a storage unit 60, a control unit 61, and a communication unit 62, similarly to the first embodiment.

[0050] The storage unit 60 stores a humidity control program 600B, user management information 601B, and room management information 602.

[0051] The user management information 601B is information for managing the users U who use the room 10. In the user management information 601B, for each user U, for example, the amount of sebum of the user U and the location indicating the room 10 where the user U is located are registered in association with each other.

[0052] The room management information 602 is information for managing the room 10. In the room management information 602, for example, a target temperature, a target humidity, and the range of the indoor space of the room 10 are registered in association with each other for each room 10.

[0053] The control unit 61 functions as a sebum amount acquisition unit 610, a target humidity setting unit 612, a location acquisition unit 613, and a notification information generation unit 614 by executing the humidity control program 600B.

[0054] The sebum amount acquisition unit 610 acquires the amount of sebum of each user U. In this embodiment, the sebum amount acquisition unit 610 receives the amount of sebum of the user U measured by the user terminal device 5 via the network 7, and registers it in the user management information 601B.

[0055] The location acquisition unit 613 receives the current location of user U acquired by the user terminal device 5 via the network 7, identifies the location of user U from the current location of user U, and registers it in the user management information 601B. The location acquisition unit 613 acquires the location indicating the room 10 in which user U is located, by, for example, referring to the range of the room 10 registered in the room management information 602, identifying which room 10 the current location of user U falls within.

[0056] The target humidity setting unit 612 sets a target humidity for each room 10 based on the amount of sebum for each user U acquired by the sebum amount acquisition unit 610 and the location of each user U acquired by the location acquisition unit 613.

[0057] In this embodiment, the target humidity setting unit 612 acquires the amount of sebum and the location of each user U by referring to the user management information 601B, and sets the target humidity for each room 10 based on the amount of sebum of each user U residing in each room 10 and the number of users U residing in each room 10. For example, the target humidity setting unit 612 calculates the ratio of users U residing in the room 10 who have a lower amount of sebum than the sebum amount reference value based on the amount of sebum and the location of each user U, and sets the target humidity for the room 10 with a higher ratio than the target humidity for the room 10 with a lower ratio. Then, the target humidity setting unit 612 registers the target humidity for each room 10 in the room management information 602. Note that the specific method for setting the target humidity is the same as that of the first embodiment, and therefore a detailed description will be omitted.

[0058] When the sebum amount of the user U is newly acquired by the sebum amount acquisition unit 610, the notification information generation unit 614 generates notification information to notify the user U of a room 10 corresponding to the sebum amount among the multiple rooms 10. For example, when a new user U enters the building through an entrance of the building and the sebum amount of the user U is newly acquired, or when the sebum amount of a user U already in the room 10 is newly acquired, the notification information generation unit 614 determines whether the sebum amount of the user U is lower than the sebum amount standard value. Then, when the sebum amount of the user U is lower than the sebum amount standard value, the notification information generation unit 614 refers to the room management information 602 and generates notification information to notify the user U to enter or move to a room 10 with a high target humidity, and transmits the notification information to the user terminal device 5 carried by the user U.

[0059] (Operation of humidity control device 6B) Next, the operation of the air conditioning system 1B having the above configuration will be described, focusing on the humidity control device 6B.

[0060] Fig. 6 is a flowchart showing an example of the operation of the humidity control device 6B according to the second embodiment. The series of processes (humidity control method) shown in Fig. 6 are executed by the humidity control device 6B, for example, when a new user U enters any one of the rooms 10. Note that the series of processes shown in Fig. 6 may be executed at a predetermined time or at predetermined time intervals, as in the first embodiment, or may be executed when the number of users U exceeds a predetermined threshold or a change in the number of users U exceeds a predetermined threshold. In that case, steps S200, S201, and S220 described later may be omitted.

[0061] First, when a new user U enters any of the rooms 10, the user terminal device 5 carried by the new user U transmits the amount of sebum measured by the sebum amount measurement function to the humidity control device 6B together with the user identifier of the user U. As a result, in step S200, the sebum amount acquisition unit 610 receives (acquires) the user identifier and sebum amount of the user U from the sebum amount measurement device 3.

[0062] Then, in step S201, sebum amount acquisition section 610 registers the information received in step S200 (user identifier and sebum amount) in user management information 601B.

[0063] Next, in step S202, a user terminal device 5 carried by a user U who has entered one of the rooms 10 transmits the amount of sebum of user U measured by the sebum amount measuring function and the current location of user U identified by the current location identifying function together with user U's user identifier to the humidity control device 6B, whereby the sebum amount acquiring unit 610 and the location acquiring unit 613 receive the user identifier, sebum amount and current location of user U from the user terminal device 5. Note that if there is no change in the amount of sebum and the current location since the previous transmission and reception, the above transmission and reception may be omitted.

[0064] Then, in step S203, the sebum amount acquisition unit 610 updates the information already registered in the user management information 601B (user identifier, sebum amount, and current location) for each user U based on the information received in step S220 (user identifier, sebum amount, and current location).

[0065] Next, in steps S210 to S216, the target humidity setting unit 612 obtains the amount of sebum and location of each user U by referring to the user management information 601B, and sets the target humidity for each room 10 based on the amount of sebum of each user U present in each room 10 and the number of users U present in each room 10.

[0066] Specifically, in step S210, the target humidity setting unit 612 determines whether the amount of sebum of the users U present in the room 10 is greater than or equal to the sebum amount reference value (for example, 20 μg / cm ) based on the amount of sebum and the location of each user U. 2 ) is calculated for each 10 rooms.

[0067] Next, in steps S211A and S211B, the target humidity setting unit 612 executes a loop process for each room 10. That is, steps S212 to S216 surrounded by steps S211A and S211B are repeatedly executed for each room 10, thereby setting the target humidity for each room 10.

[0068] Based on the proportion of each room 10, if the proportion of user U is higher than a first proportion reference value (e.g., 30%) (step S212: Yes), the target humidity setting unit 612 sets the target humidity of the humidity adjustment equipment 2 to a first relative humidity R1 (e.g., 60% RH) in step S213, and if the proportion of user U is lower than a second proportion reference value (e.g., 10%) (step S214: Yes), the target humidity setting unit 612 sets the target humidity of the humidity adjustment equipment 2 to a second relative humidity R2 (e.g., 50% RH) lower than the first relative humidity R1 in step S215.

[0069] Furthermore, if the proportion of users U is lower than the first proportion reference value (e.g., 30%) and higher than the second proportion reference value (e.g., 10%) (step S212: No and S214: No), in step S216, the target humidity of the humidity control equipment 2 is set to a third relative humidity R3 (e.g., 55% RH) that is lower than the first relative humidity R1 and higher than the second relative humidity R2.

[0070] Next, in step S220, the target humidity setting section 612 registers in the room management information 602 the target humidity for each room 10 that was set in steps S210 to S216.

[0071] Next, in step S230, the notification information generating unit 614 refers to the room management information 602 and generates notification information to notify the new user U of a room 10 corresponding to the sebum amount of the user U received in step S200. For example, if the sebum amount of the new user U is lower than the sebum amount reference value, notification information is generated to notify the user U to enter a room 10 in which the target humidity is set high. The notification information generating unit 614 then transmits the notification information to the user terminal device 5 carried by the user U. The user terminal device 5 outputs the notification information, for example, on a screen or by audio, so that the user U can know which room 10 is suitable for him / her.

[0072] Then, in step S240, the target humidity setting unit 612 refers to the room management information 602 and transmits the target humidity for each room 10 to each of the multiple humidity control devices 2 that adjust the indoor environment of each room 10. As a result, the control panel 22 of each humidity control device 2 receives the target humidity for each room 10 from the humidity control device 6, and performs humidity control operation by switching the operation mode (dehumidification mode or humidification mode, strong or weak, etc.) based on the target humidity and the detected temperature and humidity of the indoor environment sensor 20, so that the humidity in each room 10 becomes the target humidity.

[0073] As described above, the humidity control device 6B according to this embodiment sets the target humidity for the humidity adjustment equipment 2 for each room 10 based on the amount of sebum of the user U who uses that room 10, thereby providing an appropriate indoor environment suited to the skin condition of the user U. This can improve the user U's satisfaction with the indoor environment.

[0074] (Other embodiments) Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and can be modified as appropriate without departing from the technical concept of the present invention.

[0075] For example, in the above embodiment, the sebum amount acquisition unit 610 has been described as acquiring the amount of sebum of the user U measured by the sebum amount measurement device 3 or the user terminal device 5, but the method of acquiring the amount of sebum is not limited to this. For example, a camera having a PTZ (pan-tilt-zoom) function may be installed in the living room 10, and the face of the user U present in the living room 10 may be recognized based on an image captured by the camera, and the amount of sebum of the user U may be measured, so that the sebum amount acquisition unit 610 acquires the amount of sebum of the user U as the measurement result. In this case, the camera installed in the living room 10 may also have a function of detecting the location of the user U.

[0076] In the above embodiment (particularly the examples of FIG. 3 and FIG. 6), the target humidity setting unit 612 has been described as setting the target humidity, for example, to a fixed three-stage value (first to third relative humidities R1 to R3) based on a comparison between the ratio of users U whose sebum amount is lower than the sebum amount reference value and the first and second ratio reference values, but the method of setting the target humidity by the target humidity setting unit 612 is not limited to the above example. For example, the target humidity setting unit 612 may set the target humidity in finer stages by dividing the ratio reference value more finely, or may linearly increase or decrease the target humidity according to the ratio for a specific section (for example, between the first ratio reference value and the second ratio reference value).

[0077] In addition, in the above embodiment, the sebum amount reference value, the ratio reference value, and the first to third relative humidity values ​​R1 to R3 used by the target humidity setting unit 612 are described as being predetermined, but at least one of these values ​​may be changed as appropriate, for example, manually by the manager of the room 10, or automatically by the target humidity setting unit 612.

[0078] As a first change method, for example, when the sebum amount acquisition unit 610 can acquire the sebum amount of the user U in the room 10 at time intervals by notifying the user U of the measurement of the sebum amount appropriately by a skin diagnosis application of the user terminal device 5 or by repeatedly measuring the sebum amount of the user U by a camera installed in the room 10, the target humidity setting unit 612 may change at least one of the sebum amount reference value, the ratio reference value, and the first to third relative humidities R1 to R3 based on the change over time of the sebum amount. For example, the target humidity setting unit 612 resets the target humidity based on the change over time of the sebum amount of the user U in the room 10 in which the target humidity is set, and when the sebum amount of the user U decreases as a change over time, the target humidity may be set higher, and when the sebum amount of the user U increases as a change over time, the target humidity may be set lower. The users U here may be some of the users U in the room 10 (for example, users U whose sebum amount is lower than the sebum amount reference value) or all of the users U. When there are multiple users U, the change in the sebum amount over time may be determined by using the change in the average sebum amount over time.

[0079] Therefore, in the above embodiment, the target humidity setting unit 612 sets the target humidity to a first relative humidity R1 (60% RH), for example, based on the amount of sebum of the user U obtained at a first time, and if the amount of sebum of the user U at a second time after a predetermined time has elapsed while the humidity control operation is being performed by the humidity control equipment 2, decreases, the first relative humidity R1 is changed to be 3% higher, and conversely, if the amount of sebum of the user U increases, the first relative humidity R1 is changed to be 3% lower.

[0080] As a second changing method, for example, the target humidity setting unit 612 may carry out a questionnaire regarding the comfort level of the indoor environment and changes in skin condition, etc., with the users U via the user terminal device 5, and analyze the correlation between the sebum amount of each user U and the questionnaire result by a statistical method or a machine learning method, thereby changing at least one value of the sebum amount standard value, the ratio standard value, and the first to third relative humidities R1 to R3. For example, when the target humidity setting unit 612 changes the sebum amount standard value (20 μg / cm 2 ), the first ratio reference value (30%), the second ratio reference value (10%), the first relative humidity R1 (60% RH), the second relative humidity R2 (50% RH), and the third relative humidity R3 (55% RH), if the questionnaire result of the user U is "dry and dissatisfied", the target humidity setting unit 612 sets the sebum amount reference value to 30 μg / cm 2 the first percentage reference value may be increased to 20%, or the first relative humidity R1 may be increased to 65% RH.

[0081] In the above embodiment, the humidity control programs 600A, 600B have been described as being stored in the storage unit 60, but they may be provided by being recorded in a computer-readable recording medium such as a CD-ROM or DVD as a file in an installable or executable format. The humidity control programs 600A, 600B may be provided by being stored on a computer connected to the network 7 and downloaded via the network 7. [Explanation of symbols]
